Oplisa japonica Pape & Kurahashi, 1994: 477. Holotype ♂, Aburayama, Fukuoka, 8.X.1988, H. Shima leg. (BLKU; examined). Type locality: Japan, Kyushu, Fukuoka, Aburayama.
Material examined. Paratypes: JAPAN (Fukuoka): 1 ♀, Mt. Tachibanayama, 16–24.IX.1978 (yellow pan trap), K. Yamagishi leg.; 1 Ƌ, same data as previous except 25–30.IX.1978; 10 ƋƋ, 5 ♀♀, same data as previous except 8– 14.X.1978; 2 ƋƋ, 8 ♀♀, same data as previous except 15–21.X.1978; 1 ♀, Mt. Inunaki, 19.X.1969, M. Honda leg. Other specimens: JAPAN (Fukuoka): 3 ♀♀, Mt. Inunaki, 28.X.1995, T. Tachi leg.; 2 ♀♀, Mt. Sefuri, 13.X.1995, T. Tachi leg.; 1 Ƌ, Nishi Park, 10.X.1995, T. Tachi leg.; 1 ♀, same as previous except 25.X.1995 (all in BLKU).
Diagnosis. Body length 3.2–4.2 mm. Wing length: 3.0–4.0 mm. Body (Fig. 30) grayish brown. Parafacial bare. Antenna with first flagellomere tongue-shaped, about 1/3 as long as eye height; scape, pedicel and basal part of first flagellomere yellowish-orange. Wing (Fig. 34) brownish hyaline, calypteres whitish yellow; wing veins brown; vein M reaching wing margin or joining vein R4+5 at apex. Halter yellow. Abdomen brown with gray pruinosity on proximal portion of tergites 3–5; sternite 5 (Fig. 21) bilobed on posterior part, lobes longer than basal part. Male terminalia (Figs 22–26): surstylus widened in basal 1/ 2 in dorsal view, narrowing in apical 1/2 and curved ventrally at middle, apex rounded in lateral view; bacilliform sclerites fused at middle with 3 projections directed anteriorly, the middle one much smaller; cercus wide over its entire length, with outer margin medially concave in dorsal view; pregonite T-shaped, ventral lobe weakly widened at middle and with some short setae at rounded apex; postgonite straight, rod-shaped, with a long seta at apical 3/4; epiphallus pointed at apex in lateral view, middle part connected to base of basiphallus, pregonite, and hypandrium by membranes; apex of distiphallus trifurcated with a membranous flag dorsally; ejaculatory apodeme distinctly widened at apex.
Distribution. Japan (Honshu, Kyushu) (Pape & Kurahashi 1994).
Host(s). Unknown.
Remarks. Oplisa Rondani comprises 9 species from the Palaearctic Region Zeegers (2011). Herting (1961) established two subgenera within the genus, Oplisa (as “ Hoplisa ”) and Anoplisa Herting. Zeegers (2011) modified the definition of the subgenera. However, most authors do not use a subgeneric classification for this genus (Kugler 1978; Pape & Kurahashi 1994; Pape 1998). We follow the latter authors because the subgenera proposed by Herting are not clearly defined.
Oplisa japonica is similar to O. oldenbergi Herting and O. nudiseta Zeegers, but can be distinguished from them by the following combination of characters: short pubescence of arista (strongly plumose in O. oldenbergi), tergite 3 with lateral marginal setae (a row of marginal setae in O. oldenbergi, these setae indistinct in O. nudiseta), and syntergite 1+2 without pruinosity (syntergite 1+2 with a pair of small pruinose areas in O. nudiseta). The morphological differences and phylogenetic relationships of O. japonica with the other species of Oplisa were mentioned in Pape & Kurahashi (1994).
