The genus Anaedus Blanchard, 1842 from China is revised. Anaedus serratus sp. nov. (Yunnan) and Anaedus nonedgus sp. nov. (Anhui, Hubei, Zhejiang) are described and illustrated. In addition to, a key to Chinese Anaedus species is given, and their geographical locations have been mapped. www.zoobank.org/urn:lsid:zoobank.org:pub:479055B1-08F6-4A35-8D45-999D46B0AEC9
Introduction Anaedus Blanchard, 1842 is distributed in the tropical and subtropical regions of Asia, and the tropical Africa, North and South America. A total of 81 species have been described by Champion (1886, 1892), Pic (1917a, b, c, 1921, 1922, 1938), Ardoin, 1973, 1976, Kaszab, 1973, 1979, Makhan, 2013, 2017; Makhan and Saeizad, 2013; Schawaller, 1994; Wang and Ren, 2007; Ardoin, 1969; Gebien, 1911; Gebien, 1920; Makhan, 2011. Ardoin (1969) synonymised two species Anaedus diversithorax Pic (1917a, b, c) and Anaedus niger Pic, 1932. Furthermore, Kaszab (1979, 1983) transferred Luprops marginicollis Fairmaire, 1896 to Anaedus and Anaedus orientalis Motschulsky, 1868 to the genus Luprops Hope, 1833. Similarly, Schawaller (2007) transferred Anaedus andohahelae Ferrer, 1998 to the genus Antennoluprops Schawaller, 2007. Arndt (1993) described the larva of A. camerunus Gebien, 1920. Ferrer (1998), Schawaller (2011) and Ferrer et al. (2016) placed Anaedus into the tribe Lupropini Ardoin (1958). Aalbu et al. (2017) constructed the phylogeny Lagriinae assigning, Anaedus to the tribe Goniaderini. In this paper, we followed this last systematic placement. Nine species of Anaedus have been recorded in China by Pic (1938) 1 species; Kaszab (1968, 1973) 2 species; Wang and Ren, 2007 4 species; Makhan and Saeizad (2013) 2 species. Most species are found in south China, except Anaedus mroczkowskii Kaszab, 1968 which was recorded in the Liaoning Province. Recent study of the Lagriinae specimens from China in the HBUM and IZCAS collection allowed the identification of two species new to science, which are here described and illustrated: A. serratus sp. nov. (Yunnan) and A. nonedgus sp. nov. (Anhui, Hubei, Zhejiang). A new identification key to Chinese Anaedus ⁎
is provided in this paper. It does not include A. aschnae Makhan, 2013 (possibly belonging to the genus Sphingocorse, and widely distributed in the Chongqing, Henan, Sichuan, Yunnan Province of China) and A. maryame Makhan, 2013 since the validity of these two species needs further confirmation and the authors did not revised the types. The geographical locations of the Chinese Anaedus species are mapped (Fig. 51). Materials and methods All specimens were examined, illustrated, photographed and measured using a Leica M205A stereomicroscope equipped with a drawing tube and Leica DFC450 camera. All measurements are in millimetres. The following abbreviations used in the text represent the studied collections. DMPC

punctatissimus Blanchard, 1842, monotypy. Synonymy: Lacordaire (1859: 396). Anaedes Agassiz, 1846: 36. Unjustifed emendation of Anaedus Blanchard, 1842, not in prevailing usage. Aspidosoma Agassiz, 1846: 36. Unjustifed emendation of Aspisoma Duponchel and Chevrolat, 1841, not in prevailing usage. Diagnosis. Body flat, brown to black. Clypeus convex; frontoclypeal suture distinctly deep; frons with irregular punctures. Antennomeres cylindrical. Pronotum with irregular punctures; anterior margin emarginate; lateral margins in most species flat and laterally expanded (expect A. nonedgus sp. nov., A. striatus Gebien, 1921 and some North American species); posterior angles acute. Elytral base slightly wider than pronotal base. Elytral surface with irregular punctures, lateral margins serrated at the base. Basal metatarsus elongated, longer than the following tarsomeres combined together. In the tribe Goniderini, the genera Pseudolyprops and Anaedus are distinguishable from other goniderine genera by the following caharcters: body wide, flat, pubesent; head prognathous; antenna filform, antennomere IX to XI not enlarged; tentorium with the transverse bridge present; pronotum strongly transverse, lateral margins of pronotum simple, often laterally expanded; lateral margins of elytra finely serrate in basal portion; disc of pronotum and elytra not sculptured; tibiae simple; basal metatarsus distinctly elongated. However, The Anaedus species can be separated from Pseudolyprops species using the following characters: body larger; anterior margin of pronotum distinctly emarginated; lateral margins of pronotum smooth and laterally expanded; basal metatarsus distinctly longer than the following tarsomeres combined together; coxite lobe IV of ovipositor much shorter than that of Pseudolyprops.

Distribution. China (Anhui, Chongqing, Hubei). Comments. The holotype of A. maryame Makhan, 2013 is a female. The females of A. mroczkowskii Kaszab, 1968 from Anhui and Hubei are similar to those of A. maryame Makhan, 2013. We retain that A. maryame Makhan, 2013 and A. mroczkowskii Kaszab, 1968 could be potentially synonyms, but since our deduction is based only on photos and original description and not type revision we prefer to remand this conclusion to another paper. 3 Anaedus mroczkowskii Kaszab, 1968 (Figs. 6–15) Anaedus mroczkowskii Kaszab, 1968: 10; Wang & Ren, 2007: 34.

Chinese species on account of its distinctly serrated lateral margins of pronotum, while the other species present smooth or toothed lateral margins (A. unidentatus Wang and Ren, 2007 with one tooth on each lateral margin of pronotum). A. serratus sp. nov. resembles A. buricus Schawaller, 1994 due to the serrated lateral margins of pronotum, but the new species differs from the later in the following characters: (1) basal margin of the pronotum without teeth, (2) male anterior tibiae without oval excavation on inner side. Etymology. The specific name is derived from “serrate”, referring to the serrate lateral margins of pronotum. Description. Body (Fig. 24) elongate-oval, flat; head and pronotum black, elytra brown, antennae and legs blackish brown; body dorsum covered with dense and long setae, erect on head and pronotum, while those on elytra and abdomen posteriorly recumbent.

Diagnosis. Pronotal lateral part of this species without distinctly extended laterally, unique character among all Chinese species. It can be separated from the others using the following characters: (1) body with indistinctly short and sparse setae in dorsal view; (2) apex of the parameres truncated and lateral margins of apicale nearly paralleled; (3) each elytron with four indistinct longitudinal carinae. Etymology. The specific name is derived from “non”and “edge”, referring to pronotum without flat, edged lateral margins. Description. Body (Fig. 41) elongate-oval, flat; body blackish brown with shining, maxillary palpus brown; doral surface of body with indistinctly short and sparse setae. Labrum subquadrate, transversely produced in the middle, with coarse punctures and erect setae; clypeus strongly convex, with straight anterior margin, apical portion without punctures, basal portion with dense coarse punctures; frontoclypeal suture straight and deep; genae strongly raised, without punctures; frons covered with coarse punctures.

Antennae (Fig. 42) robust, extending base of pronotum, terminal antennomere 1.8 times longer than width, antennomeres III–IV longer than antennomeres V–X, ratio of length of antennomeres II–XI as follows: 12.8: 28.6: 34.3: 28.4: 27.9: 29.1: 26.6: 26.6: 26.6: 40.9. Pronotum (Fig. 43) strongly transverse, 1.6 times as wide as long, widest in middle; anterior margin shallowly emarginated; lateral margins slightly flat and not expanded laterad, strongly convergent in apical half, strongly sinuous before posterior angles; posterior margin arcuate in middle, posteriorly produced; anterior angle obtuse and protruding; posterior angles acute and point outwards. Pronotal surface between lateral margins convex, with moderately dense and deep punctures on disc. Prothoracic hypomere glossy, with punctuations smaller than those on disc. Prosternal process with shallow punctuations, and slightly expanded apex. Scutellum triangular, without punctures. Elytra elongate-oval, 1.4 times as long as wide, and 1.2 times as wide as pronotum, lateral margins finely serrated in basal fifth and rounded at humeri. Elytral surface with dense and irregular punctures, disc convex, each elytron with four indistinct longitudinal carinae. Epipleura with shallow punctures. Visible abdominal ventrites I–V with sparse punctures with long setae, apex of ventrite V triangular. Legs short and thin. Tibiae straight, gradually broadening towards apex, inner apex with setae denser than outer one. Length ratio of pro-, meso- and metafemora is 1.6: 1.9: 2.2, and that of corresponding tibiae is 1.4: 1.5: 2.0. Aedeagus (Figs. 44–45): length 1.61 mm, width 0.36 mm, flat in

The genus Anaedus Blanchard, 1842 from China is revised. Anaedus serratus sp. nov. (Yunnan) and Anaedus nonedgus sp. nov. (Anhui, Hubei, Zhejiang) are described and illustrated. In addition to, a key to Chinese Anaedus species is given, and their geographical locations have been mapped. www.zoobank.org/urn:lsid:zoobank.org:pub:479055B1-08F6-4A35-8D45-999D46B0AEC9
Introduction Anaedus Blanchard, 1842 is distributed in the tropical and subtropical regions of Asia, and the tropical Africa, North and South America. A total of 81 species have been described by Champion (1886, 1892), Pic (1917a, b, c, 1921, 1922, 1938), Ardoin, 1973, 1976, Kaszab, 1973, 1979, Makhan, 2013, 2017; Makhan and Saeizad, 2013; Schawaller, 1994; Wang and Ren, 2007; Ardoin, 1969; Gebien, 1911; Gebien, 1920; Makhan, 2011. Ardoin (1969) synonymised two species Anaedus diversithorax Pic (1917a, b, c) and Anaedus niger Pic, 1932. Furthermore, Kaszab (1979, 1983) transferred Luprops marginicollis Fairmaire, 1896 to Anaedus and Anaedus orientalis Motschulsky, 1868 to the genus Luprops Hope, 1833. Similarly, Schawaller (2007) transferred Anaedus andohahelae Ferrer, 1998 to the genus Antennoluprops Schawaller, 2007. Arndt (1993) described the larva of A. camerunus Gebien, 1920. Ferrer (1998), Schawaller (2011) and Ferrer et al. (2016) placed Anaedus into the tribe Lupropini Ardoin (1958). Aalbu et al. (2017) constructed the phylogeny Lagriinae assigning, Anaedus to the tribe Goniaderini. In this paper, we followed this last systematic placement. Nine species of Anaedus have been recorded in China by Pic (1938) 1 species; Kaszab (1968, 1973) 2 species; Wang and Ren, 2007 4 species; Makhan and Saeizad (2013) 2 species. Most species are found in south China, except Anaedus mroczkowskii Kaszab, 1968 which was recorded in the Liaoning Province. Recent study of the Lagriinae specimens from China in the HBUM and IZCAS collection allowed the identification of two species new to science, which are here described and illustrated: A. serratus sp. nov. (Yunnan) and A. nonedgus sp. nov. (Anhui, Hubei, Zhejiang). A new identification key to Chinese Anaedus ⁎
is provided in this paper. It does not include A. aschnae Makhan, 2013 (possibly belonging to the genus Sphingocorse, and widely distributed in the Chongqing, Henan, Sichuan, Yunnan Province of China) and A. maryame Makhan, 2013 since the validity of these two species needs further confirmation and the authors did not revised the types. The geographical locations of the Chinese Anaedus species are mapped (Fig. 51). Materials and methods All specimens were examined, illustrated, photographed and measured using a Leica M205A stereomicroscope equipped with a drawing tube and Leica DFC450 camera. All measurements are in millimetres. The following abbreviations used in the text represent the studied collections. DMPC

punctatissimus Blanchard, 1842, monotypy. Synonymy: Lacordaire (1859: 396). Anaedes Agassiz, 1846: 36. Unjustifed emendation of Anaedus Blanchard, 1842, not in prevailing usage. Aspidosoma Agassiz, 1846: 36. Unjustifed emendation of Aspisoma Duponchel and Chevrolat, 1841, not in prevailing usage. Diagnosis. Body flat, brown to black. Clypeus convex; frontoclypeal suture distinctly deep; frons with irregular punctures. Antennomeres cylindrical. Pronotum with irregular punctures; anterior margin emarginate; lateral margins in most species flat and laterally expanded (expect A. nonedgus sp. nov., A. striatus Gebien, 1921 and some North American species); posterior angles acute. Elytral base slightly wider than pronotal base. Elytral surface with irregular punctures, lateral margins serrated at the base. Basal metatarsus elongated, longer than the following tarsomeres combined together. In the tribe Goniderini, the genera Pseudolyprops and Anaedus are distinguishable from other goniderine genera by the following caharcters: body wide, flat, pubesent; head prognathous; antenna filform, antennomere IX to XI not enlarged; tentorium with the transverse bridge present; pronotum strongly transverse, lateral margins of pronotum simple, often laterally expanded; lateral margins of elytra finely serrate in basal portion; disc of pronotum and elytra not sculptured; tibiae simple; basal metatarsus distinctly elongated. However, The Anaedus species can be separated from Pseudolyprops species using the following characters: body larger; anterior margin of pronotum distinctly emarginated; lateral margins of pronotum smooth and laterally expanded; basal metatarsus distinctly longer than the following tarsomeres combined together; coxite lobe IV of ovipositor much shorter than that of Pseudolyprops.

Distribution. China (Anhui, Chongqing, Hubei). Comments. The holotype of A. maryame Makhan, 2013 is a female. The females of A. mroczkowskii Kaszab, 1968 from Anhui and Hubei are similar to those of A. maryame Makhan, 2013. We retain that A. maryame Makhan, 2013 and A. mroczkowskii Kaszab, 1968 could be potentially synonyms, but since our deduction is based only on photos and original description and not type revision we prefer to remand this conclusion to another paper. 3 Anaedus mroczkowskii Kaszab, 1968 (Figs. 6–15) Anaedus mroczkowskii Kaszab, 1968: 10; Wang & Ren, 2007: 34.

Chinese species on account of its distinctly serrated lateral margins of pronotum, while the other species present smooth or toothed lateral margins (A. unidentatus Wang and Ren, 2007 with one tooth on each lateral margin of pronotum). A. serratus sp. nov. resembles A. buricus Schawaller, 1994 due to the serrated lateral margins of pronotum, but the new species differs from the later in the following characters: (1) basal margin of the pronotum without teeth, (2) male anterior tibiae without oval excavation on inner side. Etymology. The specific name is derived from “serrate”, referring to the serrate lateral margins of pronotum. Description. Body (Fig. 24) elongate-oval, flat; head and pronotum black, elytra brown, antennae and legs blackish brown; body dorsum covered with dense and long setae, erect on head and pronotum, while those on elytra and abdomen posteriorly recumbent. Male. Labrum transverse, transversely produced in the middle, with coarse punctures; clypeus strongly convex, anterior margin straight, surface with coarse punctures; frontoclypeal suture straight and deep; 93

Diagnosis. Pronotal lateral part of this species without distinctly extended laterally, unique character among all Chinese species. It can be separated from the others using the following characters: (1) body with indistinctly short and sparse setae in dorsal view; (2) apex of the parameres truncated and lateral margins of apicale nearly paralleled; (3) each elytron with four indistinct longitudinal carinae. Etymology. The specific name is derived from “non”and “edge”, referring to pronotum without flat, edged lateral margins. Description. Body (Fig. 41) elongate-oval, flat; body blackish brown with shining, maxillary palpus brown; doral surface of body with indistinctly short and sparse setae. Labrum subquadrate, transversely produced in the middle, with coarse punctures and erect setae; clypeus strongly convex, with straight anterior margin, apical portion without punctures, basal portion with dense coarse punctures; frontoclypeal suture straight and deep; genae strongly raised, without punctures; frons covered with coarse punctures. Eyes transversely reniform, slightly divided by genal canthus; in dorsal view, temple length about 2 times as long as eye diameter; width at narrowest point of eye equal to 3–4 ommatidia in lateral view. Antennae (Fig. 42) robust, extending base of pronotum, terminal antennomere 1.8 times longer than width, antennomeres III–IV longer than antennomeres V–X, ratio of length of antennomeres II–XI as follows: 12.8: 28.6: 34.3: 28.4: 27.9: 29.1: 26.6: 26.6: 26.6: 40.9. Pronotum (Fig. 43) strongly transverse, 1.6 times as wide as long, widest in middle; anterior margin shallowly emarginated; lateral margins slightly flat and not expanded laterad, strongly convergent in apical half, strongly sinuous before posterior angles; posterior margin arcuate in middle, posteriorly produced; anterior angle obtuse and protruding; posterior angles acute and point outwards. Pronotal surface between lateral margins convex, with moderately dense and deep punctures on disc. Prothoracic hypomere glossy, with punctuations smaller than those on disc. Prosternal process with shallow punctuations, and slightly expanded apex. Scutellum triangular, without punctures. Elytra elongate-oval, 1.4 times as long as wide, and 1.2 times as wide as pronotum, lateral margins finely serrated in basal fifth and rounded at humeri. Elytral surface with dense and irregular punctures, disc convex, each elytron with four indistinct longitudinal carinae. Epipleura with shallow punctures. Visible abdominal ventrites I–V with sparse punctures with long setae, apex of ventrite V triangular. Legs short and thin. Tibiae straight, gradually broadening towards apex, inner apex with setae denser than outer one. Length ratio of pro-, meso- and metafemora is 1.6: 1.9: 2.2, and that of corresponding tibiae is 1.4: 1.5: 2.0. Aedeagus (Figs. 44–45): length 1.61 mm, width 0.36 mm, flat in
