The subfamily Cylapinae (Hemiptera: Heteroptera: Miridae) is first reviewed from Eastern continental region, the Korean Peninsula, with findings of four newly recorded species. The tribe Bothriomirini Kirkaldy is recognized for the first time based on the specimens of Bothriomiris gotohi Yasunaga, 2000. The genera Fulvius and Peritropis are also first reported with discoveries of F. ussuriensis Kerzhner, 1973, F. nozawai Yasunaga & Wolski, 2017, and P. advena Kerzhner, 1973. The record of genus Punctifulvius is confirmed on the basis of the species of Punctifulvius kerzhneri Schmitz, 1978. The variable character of F. nozawai between populations and ambiguous character of B. gotohi are discussed. The morphological information including diagnosis and brief biology of each species are presented. A key to the cylapine species in the continental region of Eastern Palaearctic Hemisphere is also provided.

Keywords: Cylapinae Continental region Eastern Hemisphere Miridae New record

Introduction The subfamily Cylapinae (Hemiptera: Heteroptera: Miridae) is a small group and considered as one of the basal groups in Miridae (Jung and Lee 2012). This group is also known to be associated with fungi on decaying wood or rotten logs, suggesting probably fungalinhabiting mycetophagous group (Yasunaga 2000; Yasunaga and Miyamoto 2006). This subfamily includes more than 360 described species and is distributed in all zoogeographical regions (Namyatova et al 2018; Schuh 2002e2013). However, many of them (ca. 100 species) are reported from the Oriental Region (Wolski and Gorczyca 2012). Although many groups and species have been revised and described in many regions over the last two decades (e.g., Carvalho and Costa 1994; Cassis et al 2003; Gorczyca 1998; Wolski 2010; Wolski and Henry 2015; Wolski et al 2016), taxonomic knowledge of this group is still poorly understood. In Eastern Palaearctic Hemisphere, Japanese fauna was recently investigated (Yasunaga 2000; Yasunaga and Miyamoto 2006; Yasunaga and Wolski 2017).

However, there has been no study for continental fauna since Kerzhner (1973) and Schmitz (1978) described some species from Far East Russia. In this study, the subfamily Cylapinae is first reviewed in continental region, the Korean Peninsula. The tribe Bothriomirini and two genera Peritropis and Fulvius are recognized for the first time. Redescription of three previously described species is provided. Diagnosis and description including male or female genitalia of each species are also presented with photographs and illustrations. A key to continental cylapine species in Eastern Palaearctic Hemisphere is provided. Photographs of dorsal habitus of each specimen were taken using a Leica M165C microscope (Leica, Germany). Measurements were taken using the software program of the same microscope. All measurements are given in millimeters (mm). Terminology mainly follows Yasunaga (2000) for general morphology. For general female genitalia, Pluot-Sigwalt and Matocq (2017) is followed. In case of female genitalia of Bothriomirini, terminology follows Namyatova et al (2018). Specimens are deposited at the Laboratory of Systematic Entomology, Chungnam National University (CNU), Daejeon, Korea. New distributional data were indicated with an asterisk.

Specimen examined. 2\\, Samdu-ri, Wando-gun, Jeollanam-do, Korea, 25 vii 2016 (J. Kim leg.)-coll. CNU. Distribution. Japan and Korea*. Biology. All specimens of this species were collected from mixed forest in the southernmost part of the Korean Peninsula. Remarks. Yasunaga (2000) described and illustrated female genitalia with a pair of sclerotized ring. However, the rings are absent in the specimens examined for this study, which is the same situation indicated in Namyatova et al (2018) based on paratype specimen. Because weak sclerotized rings sometimes could be absent during experiment depending on condition of specimen, more examination is needed to verify whether this ambiguous character can be a variable character or examined specimens here are not conspecific.

The nymph and adult of this species are usually found on bark of decaying or rotten logs with fungi (Figure 6AeB). This species is also attracted to artificial light trap. Remarks. In original description (and illustration) of this species, fore and mid femora are pale brown except for reddish apex (Yasunaga and Wolski 2017), while fore and mid femora of the specimens examined in Korean population are distinctly dark brown (Figure 2A). We considered this condition to be a variable character and finally identified this species as F. nozawai here, based on external characters (coloration of dorsal habitus and second antennal segment, proportion of pale part of hemelytra and body length) and distribution using female specimens. Therefore, future study based on male specimens is needed to verify whether Korean population is conspecific.

Kim leg.)-coll. CNU. Distribution. Japan, Russia, and Korea. Biology. This species is usually found on the bark of decaying or rotten logs with fungi and is distributed in the whole region in Korea, including subtropical Jeju Island (Figure 6D). This species is also attracted to artificial light trap. Key to continental species of Cylapinae in Eastern Palaearctic Hemisphere 1.
