Galerotella garoana Maulik, 1936: 271 ; Kimoto, 1979: 464 (synonymized with Pyrrhalta dimidiaticornis ). FIGURES 9–17. Male genitalia of Menippus species. a: lateral view; b: dorsal view. 9. M. asahinai ; 10. M. beeneni ; 11. M. dimidiaticornis ; 12. M. gressitti ; 13. M. hsuehleeae ; 14. M. issikii ; 15. M. murzini ; 16. M. nepalensis ; 17. M. sericea . Male. Length 8.3–8.6 mm . Color: brown; antennae blackish brown except two basal antennomeres pale; legs brown. Sculpture: head, pronotum and elytra with small, extremely dense punctures. Antenna short, reaching midpoint of body, all antennomeres elongate, relative length of antennomeres II–XI about 1.0: 1.4: 1.9: 1.7: 1.6: 1.7: 1.5: 1.6: 1.4: 1.9. Pronotum widest at apical 1/3, gradually narrowed towards base; pronotal disc with 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 close, 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 slender and weakly curved in lateral view, apically constricted ( Fig. 11 a); in dorsal view subapically tapering and slightly asymmetric, apex rounded ( Fig. 11 b). Apex of endophallic sclerite narrowly rounded ( Fig. 11 b). Female. Length 8.8–9.4 mm . Similar to male. Apex of last ventrite truncate. Sternite VIII well sclerotized ( Fig. 21 ), apex slightly concave at middle, with dense extremely long setae along apical margin, spiculum extremely long. Spermathecal receptaculum strongly swollen ( Fig. 28 ), strongly narrowed between receptaculum and pump, pump narrow and curved; spermathecal duct narrow, slightly projecting into receptaculum. Gonocoxae ( Fig. 35 ) separated, extremely reduced, very small, without setae. Diagnosis. This species can be distinguished from other members of Menippus dimidiaticornis group by the weakly curved and symmetric penis with apically tapering apex. Type material examined.

Notes. Menippus dimidiaticornis was transferred to the genus Pyrrhalta ( Kimoto 1979 ) , then to Issikia ( Kimoto 1989b ) . Now its status need to be restated as Issikia is a junior synonym of Menippus .
