Cosmiomorpha (Cosmiomorpha) nigripedis Qiu & Xu, new species

( Figs. 5 , 29–30 , 44 , 57 , 73 , 143–144 , 155, 162 , 169 , 172 )

Diagnosis. This species is more similar to C. sauteri than C. decliva : body luster is weaker; the tarsi and tibiae black ( Fig. 143 ); the deflexed tooth larger than C. sauteri but smaller than C. decliva ( Fig. 57 ); the clypeal margin strongly raised ( Fig. 29 ).

Holotype (male). TL: 23.5 mm, TW: 10.0 mm, CW/CL: 1.09. Head: Black, flat, vertex with a slightly raised longitudinal ridge; dorsal surface densely microsculptured, punctures small, round or elliptical; few punctures with sparse, radially distributed, short scales. Clypeus subtrapezoidalal in ventral view, margin evidently raised, anterior margin with a deep central depression. Gula smooth, almost without puncture ( Fig. 30 ). Antenna dark brown.

Pronotum: Dark orange, with 3 confluent black maculae. Black macula on disc large, occupying most of the surface and confluent with the two small elliptical maculae close to the lateral margins respectively; dorsal surface with numerous small round setiferous punctures, sparser, comparatively larger and deeper on disc; scales small, long elliptical, yellow ( Fig. 73 ); margins smooth and black. Scutellum: Black, with few setiferous punctures, scales yellow. Elytra: Dark orange with humeral umbone, basal and anteromesal portion and sutural costa black; with numerous setiferous punctures, punctures denser on postdiscal portion; scales short, long elliptical, yellow. Sternum: Clad with linear scales, dense on mesosternum and both sides of metasternum; scales comparatively short, fulvous. Mesosternal process long with a constriction in the middle, apex truncate, glabrous ( Fig. 5 ). Pygidium: Dark orange, rugose; with sparse, short, yellow scales. Abdomen: Sternites dark brown; a longitudinal groove between abdominal sternites 3–5; the sternites 2–6 with numerous linear scales except for medial area, the medial area with few setiferous punctures, scales inapparent; the last sternite almost glabrous, with a few setiferous punctures on both sides and a row of short fulvous setae along posterior margin. Legs: Black, with central portion of femora dark brown. Coxae densely clad with linear scales. Trochanters glabrous. Ventral surface of femora covered with short, sinuous striolae and sparse, tiny, yellow scales. Tibiae with numerous punctures and sparse, tiny scales. Protibia slim; three teeth along outer margin of which the proximal tooth nearly absent, the distance between the middle and proximal teeth about 1.5 times between the distal and middle teeth ( Fig. 44 ); a row of mastoid teeth on ventral surface; the deflexed tooth distinct, short, blunt ( Fig. 57 ). Mesotibia and metatibia with a blunt spine in the middle of outer margin; a row of sparse brush-like, yellow setae along inner margin. Protarsus slim; basitarsus slightly clavate. Parameres: Elongate, outer margins slightly expanded in apical view; apex slightly rounded with a tuft of long golden setae ( Figs. 155, 162 ). Female. Unknown.

Type material. Holotype: CHINA: Guizhou: ♂ (SWUC, ex QCCC, No.538), 11.VIII.2012, Maolan National Nature Reserve, Libo County, alt. 740 m, Jian-Yue Qiu & Hao Xu leg, on pear ( Pyrus species; Rosaceae ).

Etymology. The species epithet comes from the Latin words “ niger ” and “ pes ” meaning “black” and “leg” respectively, for this species is similar to C. decliva in Asian continent, but with black legs.

Distribution. China: Guizhou.

Natural history. This specimen was collected from a pear tree as it was feeding on a pear fruit with Cosmiomorpha (Microcosmiomorpha) setulosa Westwood , one Parapilinurgus species, and more than one Protaetia species.
