Type locality. Australia, Western Australia, 17.5 km SE Burranbar Pool, on Savory Creek, 24°55'23.1"S, 120°31'51.6"E.

Description (male, holotype). Head and pronotum reddish brown, head moderately darker; elytra brown black, with paler, rufous brown lateral margins, suture (except apical third) and two transverse bands (Fig. 77); bands more or less fused with rufous brown strip on suture and paler lateral margin, the anterior one widened laterally; legs and palpi rufous, antennae darker, rufous brown.

Head 1.3 times as long as wide, moderately widely rounded posteriorly in dorsal view; posterior temporal angles indicated. Eyes small, moderately convex. Dorsal surface nearly matte, densely punctured (Fig. 77); punctation double, rather evenly developed. Setation short, appressed, with a few slightly longer, inconspicuous, erect setae. Antennae only moderately enlarged in terminal third; antennomere III 1.8 times as long as wide, about as long as IV; antennomere X 1.5 times, XI 2.1 times as long as wide.

Pronotum nearly as long as wide, distinctly wider than head, widely rounded anteriorly in dorsal view. Pronotal disc moderately convex, rather conspicuous, ist lateral margins forming blunt edge, lateral outlines slightly sinuously narrowing towards base in dorsal view. Dorsal surface nearly matte, densely punctured; punctation similar to that on head, punctures slightly denser, larger and rather oval shaped. Setation as on head.

Elytra 1.8 times as long as wide, conjointly rounded apically. Surface nearly matte, rather densely punctured (Fig. 77); basal punctation double, but coarse punctures somewhat less distinct, smaller than those on head. Setation longer than on head, subdecumbent setae mostly dark coloured and evenly directing posteriad, setae of transverse bands whitish/silvery and partly oblique (swirled medially), forming setose bands; erect setae sparsely scattered and less conspicuous.

Metafemora unidentate (Fig. 78), subapical process pointed apically, facing inner side of tibia. Mesotibiae with slight denticle on inner side apically. Setation rather uniformly short, fine, appressed.

Abdominal sternum III with small protuberance medially at about mid-length. Sternum VII simple, evenly rounded posteriorly. Tergum VII simple. Sternite VIII (Fig. 79); paired prongs strongly widened, their distal, flattened portion triangular, simply rounded apically, rather densely, finely setose ventrally, and with conspicuous, dense fringe of blunt, stiff setae near postero-median angle. Tergite VIII simple, with posterior margin evenly rounded.

Aedeagus (Figs 80); apical portion of tegmen 1.1 times as long as basal-piece, rather wide, moderately, sinuously narrowing towards truncate apex in dorsal view, moderately bent in lateral view, with small, rounded apical process/lobe; median lobe of aedeagus simple, its ventral side more sclerotized in apical third.

Female. Unknown.

Body length (♂). 3.1−3.4 mm (holotype 3.4 mm).

Variation. The paratype specimen is generally paler coloured.

Differential diagnosis. C. comes sp. nov. differs from most species by the combination of the unidentate metafemora, generally rather short body setation (erect setae inconspicuous), and the simply punctured elytra, with paler markings and setose bands. It shares these external characters with C. paganus sp. nov., C. quadrimaculatus, C. tuberculifer sp. nov. and C. volselifer sp. nov., but differs by the rather sharply defined lateral margins of the pronotal disc (closely posterior to the widest point) and by all the male characters.

Etymology. From Latin comes (attendant, companion); named in reference to its sympatric occurrence with C. communis sp. nov.

Distribution. Australia (Western Australia).
