(figs 9, 10, 76–87, 365)  
 Diagnosis. This species is very similar to C. olivaceus sp. n. and C. grebennikovi sp. n.; differs by very short erect setae on elytral intervals: anterior declivity with setae up to a third of interval width (in C. olivaceus sp. n. and C. grebennikovi sp. n. —0.5). From C. bellus it differs by setae of elytral intervals 1–6 subrecumbent and very short (a third to half as long as interval width); genae bare, with oblique stripes of green scales; background coloration of body dorsal surface brownish-olivaceous; pale stripes of elytral intevals 2 and 4 interrupted at disk; eyes smaller and strongly convex [FW/ELD: 1.36–1.5 (1.43)].   
 Description.   
 Measurements. BL: 3.55–3.92 (3.69) mm; BW: 1.87–1.97 (1.93) mm; BH: 1.62–1.82 (1.73) mm.   
 Vestiture. Body densely covered only with overlapping, round scales, setose. Setae of head form rows along lateral edges of epifrons (recumbent or subrecumbent) and above the eyes (erect). Subocular row consists of 4 setae. Temples with broad bare stripe. Elytral intervals 1–6 with distinct row of subrecumbent setae. Anterior half of elytra with rather short setae (one third as long as interval width), posterior declivity with rather long, erect, thick, truncate spatulate setae (half as long as interval width). Genae bare, with oblique green stripes, occasionally densely squamulate. Ventrites densely squamose, anal ventrite with apical setal comb. Antennal scape setose and densely squamose; scales round; setae long, slender, acute, and erect. Funicle setose, funicular segments 1–3 with elongate scales Metatibiae with small grooming brush; hairs short. Tarsi setose and squamose.   
 Coloration. Background scaling brownish-olivaceous; striped pattern formed by green and cupreous scales. Dark and pale scales both with slightly pronounced pearl shine. Head dorsal surface brown, with green stripes around eyes and antennal sockets; temples, anterior portion of epifrons, and pterygia green. Pronotum with deepbrown background scaling and 3 longitudinal cupreous stripes (fused; sides with green scales. Elytra background scaling brown. Intervals 1, 5–7 (subdeclivital portion), 9–11 green. Discal portion of intervals 1–3 brown, declivital portion grayish-cupreous. Occasionally anterior portion of intervals 2–6 with alternate brown and gray striped pattern. Ventral side of head (except for hls-ptp callosity) and pronotum green, meso- and metapleura cupreous. Femora brown-cupreous, proximal portion and ventral surface with green scales. Tibiae external surface cupreous or greenish-cupreous.   
 Head. Rostrum weakly elongate to elongate [RL/RW: 1.11–1.22 (1.17)], parallel-sided. Pterygia not extended beyond contour of rostrum. Lateral carinae scarselly convex. Epifrons very narrow, parallel-sided, at the level of antennal articulation 2.8–3 x narrower than vertex, distinctly sloping at sides, with convex median carina. Transverse sulcus deep, concealed by dense scaling at dorsal surface and at sides. Anterior portion of epifrons not steep, without median sulcus. Frons horizontal, glabrous, bare. Epistome convex, broadly arcuate, delimited by narrow carina. Eyes small, broadly oval, sublateral, strongly convex, highest at the middle [FW/ELD: 1.36–1.50 (1.43)]. Vertex broad, flat. Frontal fovea concealed by scales.   
 Antennae. Scape extended behind anterior edge of pronotum, evenly curved and widened. funicular segment 1 as long as 2nd; 3rd–7th oblong.   
 Thorax. Pronotum strongly transverse, evenly slightly convex at sides, constricted at apex, widest at middle [PL/PW: 0.80–0.81 (0.81)]. Disc weakly convex longitudinally and transversally. Tergosternal and Metanepisternal sutures concealed by scales. Metanepisternal suture obsolete posteriorly.   
 Elytra. Oval to broadly-oval [EL/EW: 1.20–1.33 (1.26)], anterior edge arcuate, vertical, narrowly rounded; disc strongly convex [EL/BH: 1.34–1.45 (1.41)]. Subscutellar callosity hidden by scales, with 2 tiny tubercles. Elytral intervals flat. Anterior portion of 1st striae with regular row of tiny tubercles.   
 Legs. Protibiae and mesotibiae moderately curved, not widened at the apex. Interior edge C-shaped, without teeth in distal portion. Metatibiae with small teeth on interior edge. Mucro well developed, thorn-shaped, acute. Setal comb of protibiae consists of sparse 8–9 black setae not extending beyond external edge of tibiae; bevel of metatibiae narrowly enclosed; its surface bare. Tarsi robust; tarsomere 2 triangular, 1.5 x as long as wide; tarsomere 3 with two wide lobes; tarsomere 5 of metatarsus extending beyond apical lobes of 3rd by length of the last one.   
 Abdomen. Posterior margin of 1st ventrite straight. 2nd ventrite 1.5 x as long as 3rd one, posterior margin of 2nd ventrite straight. 5th ventrite weakly convex near the apex; apical edge acute.   
 Male genitalia. Male unknown.   
 Female genitalia. Coxites heavily sclerotized dorso-ventrally curved, with heavily sclerotized dorsal baculi, evenly covered with pores, without sensilla. Styli well developed, stick-shaped, bearing 1 seta. Spermatheca moderately sclerotized, with oblong, thick ramus; collum slender, as long as ramus; corpus large, slightly swollen. cornus thick, extended beyond corpus. Tergite 8 subtrapezoid, with sparse arcuate setal fringe; setae tenuous, short. Sternite 8 thick. Lamella sharply narrowed and acute, without setae, knife-shaped, heavily sclerotized. Apodeme thick; caput small.   
 Distribution. Burundi (Ruvube River) (Fig. 365).   
 Bionomics. Unknown.   
 Material examined. Burundi: Holotype, ♀, dissected (TAU) “102673 BURUNDI / Muyinga Province, / Ruvube Nat. Park / 2° 59'S 30° 28'E / 1350m 31.i.2011 / A. Freidberg ”. Paratypes 2♀, (TAU, ZMUN) labeled as holotype, 1 female dissected.   
 Etymology. The name is a noun and refers to the Burundi, a country in Central Africa, where this species occurs.
