Mimonemophas multimaculatus Xie & Wang , sp. nov.

( Figs. 5–6, 10–14 )

Material examined. Holotype (female): CHINA, Hubei, Yingshan, Wujiashan, 13 July, 2007, leg. Wenjuan Tao (YZU).

Distribution. CHINA (Hubei).

Female. Length 22.0 mm, humeral width 8.0 mm. Body completely black, clothed with dense appressed bright iridescent bluish to bluish-grey scale-like pubescence and thick semirecumbent to suberect black bristle-like hairs. Head clothed with bright iridescent bluish pubescence on anterior margin of frons, labrum, outer side of basal mandible, gena and around low eye lobe margin. Antenna with basal two antennomeres and extreme base of 3rd antennomere clothed with bright iridescent bluish to pale blue pubescence. Pronotum mostly glabrous, decorated with a rather vague (hardly notice but really exist) oblique stripe of sparse bright iridescent bluish pubescence on each side of mid-line between anterior and posterior transverse grooves, and several black short hairs behind lateral spine. Scutellum clothed with pale blue pubescence at the edge. Elytra mostly clothed with dense bluish to bluish-grey pubescence and the remaining clothed with dense black bristle-like hairs, scattered with numerous thinner and shorter inconspicuous bristle-like hairs throughout bluish-grey pubescent area except for epipleuron which is completely clothed with bright iridescent bluish to pale blue pubescence. Each elytron decorated with a black basal transverse band interrupted by two vague longitudinal stripes of pale blue pubescence, and 14 to 17 black patches of variable size approximately arranged in 5 to 6 transverse rows. Ventral surface clothed with thin bright iridescent bluish pubescence, pubescence on metasternum, metapleura and sternite slightly dense, pro- and mesosternum clothed with black hairs; apex of distal abdominal segment fringed with black hairs. Legs mostly clothed with bright iridescent bluish to pale blue pubescence except meso- and metatibiae with about apical half clothed with black setae dorsally.

Head finely punctate; frons wider than tall, with a central sulcus extending to occiput; interantennal region deeply impressed; eye coarsely faceted, low lobe taller than wide, about 2 times as long as gena. Antenna slightly robust, about 1.4 times as long as body; antennal tubercles moderately elevated, scape stout, slightly flat and sparsely punctate, with a broad cicatrix; 3rd antennomere longer than 4th, about 1.5 times as long as scape, 4th to 10th antennomere successively decreased in length, 11th antennomere about as long as 8th. Pronotum wider than long; lateral spine coniform, short; disc sparsely and thinly punctate laterally, provided with five calli, of which the posteromedial one moderate with flattened top, the anterolateral two distinct and posterolateral two less distinct. Scutellum triangular, rounded apically. Elytra about 2 times as long as width across humeri, with sides subparallel and apex broadly rounded; disc finely punctate throughout and finely granulate basally. Mesosternal process moderately tuberculate. Sterna, pleura and sternite 1–4 barely punctate. Distal sternite sparsely punctate, with apex nearly straight. Legs moderately long, femur slightly clavate and sparsely punctate; tarsal claw divaricate.

Female genitalia. Bursa copulatrix long, bursiform, not thickened apically, longer than vagina. Spermatheca inserts in the bursa copulatrix near middle at the side of blind end. Spermathecal duct short. Spermathecal capsule completely membranous, lunate basally, strongly curved and reversed medially, gradually expanded and slightly sinuate apically, apex of blind end rounded. Spermathecal gland long, strongly constricted and sclerotized basally.

Remarks. The species is different from M. quadrifasciatus Breuning by the elytra which are mostly clothed with bright iridescent bluish to bluish-grey pubescence and decorated with lots of black patches arranged in 5 to 6 transverse rows. The spermathecal capsule is completely membranous, which is quite unique in Monochamini .

Etymology. The species is named for the elytra with a lot of black spots. Chinese name is spelled Duōbān Sìjūtiānniú in Chinese phonetic alphabet.
