(Figs 12, 22, 29, 37)
Issikia dimidiaticornis: Kimoto, 1989b: 13 (part).
Male. Length 7.2 mm. Color: brown; antennomeres III-XI apically darkened; legs brown. Sculpture: head, pronotum and elytra with small, extremely dense punctures. Antenna short, reaching mid-point of body, all antennomeres elongate, relative length of antennomeres II–XI about 1.0: 1.6: 2.1: 1.9: 1.9: 1.8: 1.6: 1.6: 1.6: 2.0. Pronotum widest at apical 1/3, gradually narrowed towards base; pronotal disc with a pair of circular depressions, with shallow depression medially, and transverse depression along hind margin laterally; hind margin slightly medially and laterally concave. Prosternal process reduced to a narrow keel between coxae, parallel-sided from base to apex; procoxal cavities closed, long thin hypomeral lobes reaching apex of posternal process. Elytra elongate, about 1.5X longer than wide, dorsally flat. Apex of last ventrite with a shallow concave excision. Penis extremely wide and weakly curved in lateral view, apically constricted (Fig. 12 a); in dorsal view apex slightly mucronate, extremely asymmetric; gonopore directed laterally (Fig. 12 b). Apex of endophallic sclerite curved, with dense short teeth on outer apical margin (Fig. 12 b).
Female. Length 7.8–9.5 mm. Similar to male. Apex of last ventrite truncate or weakly concave at middle. Sternite VIII well sclerotized (Fig. 22), apex slightly concave at middle, with dense extremely long setae along apical margin, spiculum extremely long. Spermathecal receptaculum strongly swollen (Fig. 29), strongly narrowed between receptaculum and pump, pump narrow and curved, receptaculum largely and laterally connected with pump; spermathecal duct narrow, slightly projecting into receptaculum. Gonocoxae separated, extremely reduced, subtriangular, single setae on tip present (Fig. 37) or absent (Fig. 36).
Diagnosis. Menippus gressitti sp. nov. is similar to M. nepalensis sp. nov. with the asymmetric penis and the toothed apex of the endophallic sclerite (Figs 12 b, 16b) but differs with relatively narrower penis in lateral view (Fig. 12 a) compared to the latter (Fig. 16 a).
