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 View FIGURES 9 – 17 a); in dorsal view apex slightly mucronate, extremely asymmetric; gonopore directed laterally ( Fig. 12 View FIGURES 9 – 17 b). Apex of endophallic sclerite curved, with dense short teeth on outer apical margin ( Fig. 12 View FIGURES 9 – 17 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 View FIGURES 18 – 25 ), apex slightly concave at middle, with dense extremely long setae along apical margin, spiculum extremely long. Spermathecal receptaculum strongly swollen ( Fig. 29 View FIGURES 26 – 32 ), 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 View FIGURES 33 – 41 ) or absent ( Fig. 36 View FIGURES 33 – 41 ).

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 View FIGURES 9 – 17 b, 16b) but differs with relatively narrower penis in lateral view ( Fig. 12 View FIGURES 9 – 17 a) compared to the latter ( Fig. 16 View FIGURES 9 – 17 a).
