( Figs 5, 6 , 17 , 25 , 32 , 40, 41 , 44 )

Galerucella sericea Weise, 1889: 622 ; Kimoto, 1979: 464 (synonymized with Pyrrhalta dimidiaticornis ).

Menippus canellinus: Chûjô, 1935: 161 ( Taiwan) .

Pyrrhalta sericea: Gressitt & Kimoto, 1963: 464 ; Kimoto, 1969: 24.

Issikia dimidiaticornis: Kimoto, 1989a: 248 ; Kimoto, 1991: 9.

Male. Length 8.0– 8.7 mm. Color ( Figs 5–6 ): brown to dark brown; antennae blackish brown except two basal antennomeres; 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: 1.3: 1.5: 1.5: 1.5: 1.5: 1.5: 1.4: 1.3: 1.4. Pronotum widest at apical 2/5, 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 sharp keel between coxae, parallel-sided from base to apex; procoxal cavities almost closed, long thin hypomeral lobes almost 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 wide and weakly curved in lateral view, abruptly constricted towards tip ( Fig. 17 a); in dorsal view apex slightly mucronate, extremely asymmetric; gonopore directed laterally ( Fig. 17 b). Apex of endophallic sclerite broad, margin smooth without tooth ( Fig. 17 b).

Female. Length 8.5–10.0 mm. Similar to male. Apex of last ventrite truncate. Sternite VIII ( Fig. 25 ) medially weakly sclerotized, apex truncate and slightly concave at middle, with dense extremely long setae along apical margin, spiculum long. Spermathecal receptaculum strongly swollen ( Fig. 32 ), abruptly narrowed between receptaculum and pump, pump narrow and curved, spermathecal duct slightly projecting into receptaculum. Gonocoxae ( Figs 35, 36 ) separated, triangular, apex with one or two long setae.

Diagnosis. Menippus sericea is similar to M. nepalensis sp. nov. and M. gressitti sp. nov. with the extremely asymmetric penis and prominent tectum ( Figs 12, 16, 17 ). This species is characterized by the smooth apex of the endophallic sclerite of the penis ( Fig. 17 b).

Host plants. Ulmaceae : Celtis sinensis Pers ; Moraceae : Morus australis Poir. , Broussonetia papyrifera (L.) L'Herit. ex Vent.; Rosaceae : Rubus swinhoei Hance ; Betulaceae : Alnus formosana (Burkill ex Forbes & Hemsl.) Makino ; Aquifoliaceae : Ilex formosana Maxim. ; Lythraceae : Lagerstroemia subcostata Koehne ; Fagaceae : Quercus variabilis Bl.

Distribution. China (Fujian, Sichuan, and Hunan) and Taiwan. This species is widespread from lowlands to elevations up to 1500 m in Taiwan ( Fig. 44 ).

Notes. Taiwanese population was originally recorded as Menippus canellinus by Chûjô (1935). Kimoto (1969) identified it as Pyrrhalta sericea . Latter Kimoto (1989a, 1991) recorded it as Issikia dimidiaticornis due to synonymy. Acutally M. sericea is a distinct species which is different from M. dimidiaticornis .

Biological notes. This species is apparently univoltine. Larvae were found in spring. A few adults were collected in light traps
