Diagnosis. Adults of both sexes are distinguished by the distinctive light orange head and pronotum, black abdomen and elytra and by the elytra densely covered in pale, recumbent setae with their apices pointed.

Description (male). 3.8-3.9 mm long (mean = 3.85 mm; n = 2); 1.8-1.9 times as long as wide. Head, thorax, coxae and prothoracic legs orange; antennae black and orange; meso and metathoracic femora black, orange on distal fifth, meso and metathoracic tibiae orange; abdomen and elytra black; elytral striae and interstriae densely bearing pale recumbent setae.

Epistoma strongly excavated, excavated from epistoma to anterodorsal margin of the eyes, excavation bordering the ocular margin; expanded to greater than quarter length of head; surface shagreened; 5 rows of setae lateral epistomal margins to median line; each lateral margin with a sub-acute vertical costa and lined with setae; apical margin armed with a short, rectangular carina; basal margin tumid above scape insertion (Fig. 2b). Frons strongly excavated from epistoma to anterodorsal margin of the eyes, excavation bordering the ocular margin; surface shagreened; bearing eight rows of erect golden setae lateral to the median line, surface moderately covered; lateral margins setose. Antennal scape elongate, expanded distally, bearing dense setae on distal three-quarters, these equal to length of scape; segments 2-7 of funicle bearing setae on ventral margin, these equal to length of funicle; setae on dorsal margin, less than

to 1.5 times length of funicle; setae on dorsal margin, less than length of 5 segments; setae on ventral margin twice as thick as those on dorsal margin; anterior face of the club setose, with a partial septum.

Apical pronotal margin broadly rounded (Fig. 5a), area between eyes lined with scales; surface minutely granulate-punctate with minute, shallow punctures; anterior fifth bearing 2-3 rows of yellowbrown setae; 1 row of yellow setae above lateral carinae; base weakly recurved (Fig. 8b); carina on lateral margin type C (Fig. 7c).

Scutellum shape type B ( Fig. 12b ).

Elytral sides parallel, narrowing to a smooth apex; base never tumid from interstriae 7-9. Disk with shallow rugosities extending from striae 1 to interstriae 4 and from the base to just beyond the scutellum, the remaining elytral surface minutely granulate. Declivital interstriae bearing uniseriate rows of yellow-brown scales. Tenth interstriae with a carina encompassing elytra. Metepisternum shape type C ( Fig. 9c ); setae palmately divided into 4 or more filaments. Mesosternum shape type E ( Fig. 10e ). Second sternite strongly convex and protuberant, the height of declivity behind greater than length of sternite 3.

Male genitalia. Median lobe strongly arcuate, lateral and apical margins with more sclerotization, apex broad, apical orifice membranous with sclerotized veins; lateral folds on basal third nearly contiguous, invaginated, projecting apically and joining at apical third forming a bilobed apex. Median struts half of body length. Internal sac central area lightly sclerotized, basal and lateral areas of seminal valve sclerotized ( Fig. 63). Tegmen semi-circular, ventral side elongated proximally. Spicule destroyed in dissection.

Etymology. This species is named in honor of our colleague, Alex Petrov, who also shares a love of Camptocerus and has generously contributed important material for this study.
