Name

Trephionus kinoshitai Habu, 1954 – Wikispecies link – Pensoft Profile

  • Trephionus kinoshitai: Habu (1954)[1]: 272, fig. 5 (holotype ♀, “Mt. Ôrenge (Hakuba), Nagano Prefecture” [Mt. Shirouma]); Habu (1978)[2]: 397, figs 799, 811, 822, 827, 832 (part); Tanaka (1985)[3]: 135, plate 25-fig. 10 (part); Yoshitake et al. (2011)[4]: 13 (part); Hovorka and Sciaky (2017)[5]: 794.
  • Synuchus nikkoensis kinoshitai: Lindroth (1956)[6]: 526, figs 21B, 22C.

Material examined

5♂1♀, Kamishiro asl. ca. 1084 m, Mt. Shirouma, Hakuba-mura, Nagano Pref. (36.739801°N, 137.813480°E), 7–16.IX.2014 (Pitfall traps baited with 10% acetic acid), K. Sasakawa leg.

Diagnosis

Similar to T. cylindriphallus sp. n. and T. niumontanus sp. n. in having secondary setae on dorsal side of mid and hind tarsal segment 5, but distinguished from the former by distinctly sinuate lateral margin of pronotum near base and from the latter by smaller body.

Description

Body length: ♂, 8.7–10.2 mm (mean ± SD: 9.5 ± 0.61 mm, n = 5); ♀, 9.0 mm (n = 1). PI: ♂, 1.21–1.29 (mean: 1.27, n = 5); ♀, 1.25 (n = 1). Head and pronotum black; elytra blackish brown to black. Pronotal lateral margins sinuate before hind angles (Fig. 2). Mid and hind tarsal segment 1 bisulcate, segments 5 with two secondary setae on dorsal side. Apex of aedeagus rounded; endophallus (Figs 10, 11) stout, directed posteriorly at basal 2/3, strongly bent right-laterally at apical 1/3; gonopore opening directed right-anterodorsolaterally; dorsobasal lobe slightly swollen; both sides of laterobasal lobe widely swollen, with BD as wide as AW; dorsoapical lobe semi-ellipsoid, with BD half of AW; sclerotization of sclerotized lobe weaker than that of aedeagus; anteroposterior length of sclerotized rim of gonopore twice longer than proximodistal length of sclerotized lobe.
