title: Descriptions Of Two New Species Of The Genus Colon Herbst (Coleoptera: Leiodidae: Coloninae) From Korea And Japan

description: This dataset contains the digitized treatments in Plazi based on the original journal article Park, Sun- Jae, Hoshina, Hideto, Ahn, Kee- Jeong (2005): Descriptions Of Two New Species Of The Genus Colon Herbst (Coleoptera: Leiodidae: Coloninae) From Korea And Japan. The Coleopterists Bulletin 59 (4): 407-413, DOI: 10.1649/787.1AbstractTwo new species, Colon (Myloechus) koreanus new species (type locality— Mt. Odaesan, Pyeongchang-gun, Gangwon Prov., Korea) and C. (M.) shini new species (type locality— Mt. Odaesan, Pyeongchang-gun, Gangwon Prov., Korea), of the genus Colon Herbst are described from Korea and Japan. Types and paratypes of the new species are designated. The subfamily Coloninae and the genus Colon are reported for the first time in Korea. Colon (Myloechus) shini is the eighth species recorded from Japan. A key to the species of Colon in Korea and Japan, and illustrations of diagnostic features of the two new species are presented.The genus Colon Herbst contains about 150 species in nine subgenera and is worldwide in distribution except for Antarctica (Peck and Stephan 1996; Newton 1998; Peck 1999). Members of Colon inhabit moist temperate forests, open tropical and temperate scrub, and grassland. Larvae are not known. Food of both larvae and adults is not known but suspected to be subterranean fungi or molds (Newton 1984; Peck and Stephan 1996).Peck and Stephan (1996) revised the North American Colon and hypothesized phylogenetic relationships of the subgenera and species groups. Seven species of the genus Colon are known to occur in Mongolia and China (Schweiger 1960; Szymczakowski 1964, 1971, 1981). In Japan, seven species have been recorded from Honshu, Shikoku, Kyushu, and Ryukyus (Hisamatsu 1970, 1985; Nakane 1982; Nishikawa 1988; Hoshina 2003). The subfamily Coloninae and the genus Colon are reported here for the first time in Korea.The genus is characterized by the following features: body length around 2–3 mm, mostly dark-brown or brown, elliptically elongate, covered with dense pubescence on dorsum; head without an occipital carina or crest; mandible with reduced and smooth molar lobes; antenna with a three-, four-, or five-articles clubbed, antennomere 8 not smaller than 7; tarsal formula 5-5- 5 in both sexes; intersegmental membranes between abdominal sternites long and brick-wall surface pattern; female with four visible abdominal sternites and male with five visible abdominal sternites; aedeagus highly specialized with median lobe reduced and with a very enlarged basal capsule (Peck and Stephan 1996).In this paper we describe two new species of the genus Colon [Colon (Myloechus) koreanus and C. (M.) shini] from Korea and Japan, provide a key to the species of Colon in Korea and Japan, and present illustrations of diagnostic features of the two new species. The terminology of taxonomic characters used in this study follows Peck and Stephan (1996). Materials for this study were collected by flight intercept trap (FIT) and sifting forest floor litter, and are deposited in the Chungnam National University Insect Collection (CNUIC, Daejeon) and at Fukui University, Fukui Prefecture.
