Trephionus babai Habu, 1978 View in CoL [Japanese name: Baba-hoso-hirata-gomimushi] Figs 5, 15
Trephionus babai : Habu (1978): 404, figs 802, 814, 815, 823, 829, 832, XXXIV-fig. 4 (holotype ♂, "Ishikiri Cave, Nakajô, Niigata Pref."); Yoshitake et al. (2011): 14; Hovorka and Sciaky ( 2017): 794.
Material examined.
1♂2♀, Mt. Ishikiri (entrance of the Ishikiri Cave), Haguro, Tainai-shi, Niigata Pref. (38.051608°N, 139.435625°E), 7-9.X.2017, H. Itô leg.
Diagnosis.
Similar to T. nikkoensis in general appearance and the absence of secondary setae on dorsal side of mid and hind tarsal segment 5, but distinguished by wider pronotum and elytral microsculpture, which is isodiametric in T. babai , but moderately transverse mesh in T. nikkoensis (see Habu, 1978). Distinguished from sympatric T. abiba sp. n. by larger body and less sinuate pronotal lateral margin near the base.
Description.
Body length: ♂, 9.3 mm (n = 1); ♀, 9.8-10.3 mm (n = 2). PI: ♂, 1.30 (n = 1); ♀, 1.34-1.37 (n = 2). Dorsal surface black. Pronotal lateral margins before hind angles barely sinuate (Fig. 5). Mid and hind tarsal segment 1 bisulcate, segment 5 lacks secondary setae on dorsal side. Apex of aedeagus rounded (Fig. 15c); endophallus (Fig. 15a, b) long oval, directed posteriorly; gonopore opening directed right-dorsolaterally; dorsobasal lobe widely swollen, with BD wider than AW; right laterobasal lobe absent; left laterobasal lobe widely swollen, with BD wider than AW; dorsoapical lobe narrowly swollen, with BD more than half of but less than AW; sclerotization of sclerotized lobe weaker than of aedeagus; sclerotized rim of gonopore not distinct.
