Introduction The family Cerophytidae Latreille, 1834 (Coleoptera: Elateroidea), known as rare click beetles, consists of 22 species in four genera worldwide: a monotypic Afrotropical genus Afrocerophytum, four species of Holarctic genus Cerophytum, and 17 species of Neotropical genera Brachycerophytum and Phytocerum (Costa et al 2003; Costa et al 2014). Among them, Cerophytum japonicum Sasaji, 1999 is a single species that is distributed in East Asia (Bocák 2007). This group can be easily distinguished from other Elateroidea families by expressing a combination of the following characters: (i) antennae 11-segmented, serrate or pectinate from antennomere 3; (ii) prosternal process wide, laterally gradually expanded at the middle on each side, then abruptly narrowed to form acute apex; (iii) metacoxal plate absent; (iv) mesotrochanters and metatrochanters elongate, more than one-half as long as the length of the corresponding femora; (v) tarsal formula 5-5-5, tarsomere 4 with ventral lobe; (vi) pretarsal claws with comb at base; (vii) abdominal ventrite 1e4 strongly connate, 5 fairly free (Sasaji 1999; Costa et al 2003).

Adults of Nearctic species, Cerophytum pulsator (Haldeman), were considered to be active and well flying based on collection records using Lindgren, malaise, and light traps in mature deciduous forests (Steiner 2000). European species, Cerophytum elateroides Latreille, were also reported from broad-leaved forests, consisting of Acer (Aceraceae), Betula (Betulaceae), Fagus and Quercus (Fagaceae), Juglans (Juglandaceae), Salix and Populus (Salicaceae), Tilia (Tiliaceae), and Ulmus (Ulmaceae) (Costa et al 2010). Cerophytid larvae were described from rotten wood associated with fungi (Rey 1887; Mamaev 1978; Lawrence 1991). In this study, we first recognized family Cerophytidae, based on a male specimen of Cerophytum japonicum Sasaji, 1999, which was collected from the deciduous forest of Yangyang-gun, Gangwon-do, Korea, in 2018. Morphological comments and photos for the species are provided. Also, male genitalia structure is described for the first time in this study. Material and methods The material examined in this study was collected using a flight interception trap (FIT) from Gangwon-do in 2018 and now deposited in the insect collection of the College for Agriculture and Life Sciences, Seoul National University (CALS, SNU, Seoul, Korea). Images for morphological characteristics were taken using a digital camera (EOS-600D, CANON, Japan) through MP-E 65-mm lens. The morphological terminology mostly follows Costa et al (2003).
