description: Menippus asahinai (Chûjô), new combination
(Figs 1, 2, 7, 9, 18, 19, 26, 33, 42)
Galerotella asahinai Chûjô, 1962: 33.
Issikia asahinai: Kimoto, 1966: 26; Kimoto, 1969: 24; Kimoto, 1991: 9; Takizawa et al., 1995: 10.
Male. Length 5.6–7.3 mm. Color (Figs 1–2): brown to dark brown; antennae and legs blackish brown. Sculpture: head and pronotum with large, extremely dense punctures, punctures on elytra relatively smaller. Antenna short, reaching mid-point of body, all antennomeres elongate, relative length of antennomeres II–XI about 1.0: 1.3: 1.2: 1.4: 1.2: 1.3: 1.2: 1.2: 1.1: 1.5. Pronotum widest at apical 2/5, abruptly narrowed at basal 1/3; pronotal disc with a pair of circular depressions, with shallow depression medially; hind margin medially and laterally slightly concave. Prosternal process reduced to a sharp keel between coxae (Fig. 7), with parallel sides 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 slender and weakly curved in lateral view (Fig. 9 a); in dorsal view, narrow and laterally parallel, subapically tapering, apex narrowly rounded (Fig. 9 b). Apex of endophallic sclerite curved with tiny teeth on apical margin (Fig. 9 b).
Female. Length 8.2–9.5 mm. Similar to male. Apex of last ventrite truncate. Sternite VIII medially weakly sclerotized (Fig. 18), apex truncate with dense long setae, spiculum short; however, well sclerotized in individuals from high mountains (Fig. 19) with spiculum apically widened, separated from apex, apex subdivided into two at middle. Spermathecal receptaculum strongly swollen (Fig. 26), abruptly narrowed between receptaculum and pump, pump narrow and curved, spermathecal duct wide, slightly projecting into receptaculum. Gonocoxae (Fig. 33) separated, tubular, apex truncate, with four or five long setae.
Diagnosis. This species is similar to Menippus hsuehleeae, sp. nov. with more prominent punctures on head and pronotum than elytra, but differs by lacking spots on pronotum and strong constriction at basal 1/3 of pronotum (Fig. 1).

Host plants. Betulaceae: Alnus formosana (Burkill ex Forbes & Hemsl.) Makino; Ulmaceae: Zelkova serrata (Thunb.) Makino; Urticaceae: Debregeasia orientalis C. J. Chen.
Distribution. This species is widespread in mountainous areas (Fig. 42) (elevation 1500–2500 m). A few specimens were also collected from areas below 1000 m elevation in north and east Taiwan during winter and early spring.
Biological notes. This species is apparently univoltine. Larvae were observed in spring. A few adults were collected in light traps.
