Etymology.The epithet of this new species is formed from the Latin “panthera” (panther or leopard), which is derived from its characteristic pronotal maculation species.
Diagnosis.This species differs from other congeners by the following combination of characters: pronotum and elytra different in color; pronotum fully dark reddish brown (rarely reddish yellow), with six blackish spots; if coloration of pronotum dark reddish brown, lateral and basal margins of pronotum always paler; elytral interstices extremely densely punctate; subcoxal lines on abdominal sternite III present; pro- and mesotarsal segments of males feebly dilated; TL/TW = 1.45 ( n= 1); lateral margins of tegmen in ventral view subparallelsided from base to basal 1/2, then strongly convergent apically; apical margin of tegmen in ventral view rounded; median lobe in ventral view subparallel-sided from base to apical 1/5, then gradually converging anteriorly; apical margin of median lobe in ventral view widely rounded; apices of gonocoxites square, with apicolateral corners widely rounded. Similar Species.This new species is similar to C. oenorubensin having a similar body shape and similar sclerites of the internal sac, but can be distinguished by the following combination of characters: pronotum with blackish spots (rarely fully blackish, but if so, lateral margins of pronotum always paler); elytral interstices densely punctate; apical margin of median lobe widely rounded in ventral view. It is also similar to C. brevicollis, known from Costa Ricaand Panama, but can be distinguished by the following combination of characters: pronotum usually with blackish spots; elytral interstices densely punctate; subcoxal lines on abdominal sternite III present.
Description.Length 1.73–2.02 (1.87) mm, width 1.44–1.65 (1.56) mm, depth 0.83–0.99 mm(0.91) ( n= 4). Male.Body ( Fig. 10D–F) round; dorsal disc of head usually dark reddish brown, rarely reddish yellow with blackish maculation on each inner margin of eye; pronotum dark reddish brown, rarely reddish yellow with 6 blackish spots;, lateral and basal margins of pronotum always paler in darker specimens; scutellum reddish yellow to dark reddish brown; elytra reddish brown to dark reddish brown, usually darker laterally than middle; antennal club dark brown except for paler apex; antennal segments I–VIII, venter, legs, and elytral epipleura reddish yellow. Head:Dorsal disc densely punctate; interspaces reticulate. Labrum feebly notched at middle. Antenna ( Fig. 14C) with club long and large, ACL/ASI-VIII = 0.80; antennal segment XI with 2 oval antennal sensillae; approximate ratio of each segment ( n= 1) 2.86: 2.33: 1.93: 1.46: 1.61: 1.00: 1.01: 1.22: 3.04: 3.03: 4.68. Pronotum:2.50–3.33 (2.93) times as wide as long ( n= 4); disc densely punctate; interspaces reticulate. Scutellum:Disc densely punctate; interspaces reticulate. Elytra:0.86–0.91 (0.90) times as long as wide ( n= 4), 2.67–3.33 (3.01) times as long as pronotum ( n= 4), widest at basal 1/3; each elytron with 9 regular rows of punctures about as large as eye facet; interstices with extremely dense, minute punctures. Venter:Prosternum feebly convex along midline. Metaventrite strongly convex. Abdominal sternite III with subcoxal lines ( Fig. 11I). Legs:slender; pro- and mesotarsal segments I to III slightly dilated; tarsal claws simple. Genitalia:Tegmen ( Fig. 14A) subparallel-sided at basal 1/2, then strongly convergent apically in ventral view; TL/TW = 1.45 ( n= 1); apical margin of tegmen rounded in ventral view; median lobe ( Fig. 14B) subparallel-sided at basal 4/5, then strongly converging anteriorly in ventral view; apical margin of median lobe widely rounded in ventral view; sclerites of internal sac as in Fig. 14B. Female.Pro- and mesotarsal segments I–III more weakly dilated than those of males. Ovipositor ( Fig. 14D) with squared apices of gonocoxites; apicolateral corners of gonocoxites widely rounded. Variability.This species varies in the pronotal maculation. The pronotum usually has 3–6 blackish spots ( Fig. 10F). However, spots are often connected ( Fig. 10E) and sometimes the pronotal disc becomes fully blackish ( Fig. 10D); if the coloration of the pronotal disc is fully blackish, then the lateral and basal margins of the pronotum are always paler.
Distribution. Ecuador, Peru, and Bolivia(Map 4).
