Wappesleg. ( ARCC).   Etymology.The specific epithet is named in honor of Dr. Richard A. B. Leschen, who is a specialist of Nitidulidae, among other families of Coleoptera.   Diagnosis.This species differs from other congeners by the following combination of characters: pronotum and elytra different in color, without any maculation on dorsal disc; anterior and lateral margins of elytra, lateral margins of pronotum and abdominal sternites always paler; metathoracic discrimen present in apical fourth; subcoxal lines on abdominal sternite III present; pro- and mesotarsal segments II and III of males strongly dilated; tegmen elongate, subparallel-sided in ventral view; TL/TW = 3.05 ( n= 1); apical margin of tegmen widely rounded in ventral view; median lobe subparallel-sided; apical margin of median lobe widely rounded and shallowly emarginate at middle; apices of gonocoxites square, with apicolateral corners widely rounded; valvifer baculus widely separated at base.  Similar Species.This new species is rather similar to  C. morulusin having similar shapes of antennal segment XI and male genitalia, but can be distinguished by the following combination of characters: pronotum and elytra different in color; anterior and lateral margins of elytra, lateral margins of pronotum, and abdominal sternites always paler; shape of sclerites of the internal sac different.   Description.Length 2.15–2.70 (2.44) mm, width 1.67–2.14 (1.94) mm, depth 1.00–1.28 (1.14) mm ( n= 4). Male.Body ( Fig. 15A) oval; dorsal and ventral disc of head (except paler dorsoapical area), antennal segments I–VIII, pronotum, scutellum, anterior and lateral margins of elytra, hypomera, elytral epipleura, and legs reddish yellow to dark reddish brown; lateral margins of pronotum and abdominal sternites always paler; antennal club dark reddish brown except paler apex, and elytra dark reddish brown except paler laterally and basally. Head:Dorsal disc densely punctate; interspaces reticulate. Labrum feebly notched at middle. Antenna ( Fig. 17C) with club long and large, ACL/ASI-VIII = 0.58 ( n= 1); antennal segment XI with 2 oval antennal sensillae; approximate ratio of each segment ( n= 1) 4.31: 2.45: 2.74: 1.81: 2.08: 1.13: 1.40: 1.00: 2.66: 2.71: 4.52. Pronotum:2.69–3.26 (2.84) times as wide as long ( n= 4); disc densely punctate; punctures on disc large, slightly smaller than eye facets; interspaces feebly reticulate. Scutellum:Disc densely punctate; punctures on disc about as large as those of pronotum; interspaces reticulate. Elytra:0.93– 0.96 (0.95) times as long as wide ( n= 4), 2.84–3.69 (3.10) times as long as pronotum ( n= 4), subparallel-sided from base to basal 1/2; each elytron with 9 regular rows of punctures about as large as eye facet; interstices with dense minute punctures. Venter:Prosternum strongly convex along midline, with tuft of setae at middle. Metaventrite strongly convex; metathoracic discrimen present in apical 1/4. Abdominal sternite III with subcoxal lines; abdominal sternite VII with dense punctures and short setae at middle of apical area; lateral margins of abdominal sternite VII strongly serrate. Legs:Robust; pro- and mesotarsal segments I–III strongly dilated; tarsal claws simple. Genitalia:Tegmen ( Fig. 17A) subparallel-sided; TL/TW = 3.05 ( n= 1); apical margin of tegmen widely rounded in ventral view; median lobe ( Fig. 17B) subparallel-sided in ventral view; apical margin of median lobe widely rounded, shallowly emarginate at middle in ventral view; sclerites of internal sac as in Fig. 17B. Female.Prosternum without tuft of setae at middle. Pro- and mesotarsal segments I–III more weakly dilated than those of males. Ovipositor ( Fig. 17D) with squared apices of gonocoxites; apicolateral corners of gonocoxites widely rounded; valvifer baculus widely separate at the base.  Variability.Coloration rarely darker; if so, lateral margins of pronotum and abdominal segments and anterior margin of elytra always paler.   Distribution. Peruand Bolivia(Map 5). 1989-06-17 SEMC R.
