Diagnosis.

Body dark orange, very finely setose, setae recumbent, impunctate; head subquadrate, posterior corners rounded, vertex slightly swollen above deeply impressed vertexal foveae; frons with oblique depressions mediad vertexal foveae; antennal bases weakly elevated in front of fine, oblique striae, striae nearly meeting across middle; eyes large, protuberant, diameter ~ 2 × post-ocular genal length; antennae short, antennomere I slightly curved, ~ 2 × as long as wide, II subquadrate, ~ 2 / 3 length of I, III subconical, slightly longer than wide, IV – VII weakly subquadrate, VIII transverse, shorter, IX – XI forming loose club, XI ~ 2 × as long as X; male pronotum (Fig. 4 M View Figure 4 ) wider than long, elevated across entire anterior margin, sides angulate at widest point, at sides of anterior elevation; deep triangular impression present behind middle of anterior elevation, with short, dense, transverse cluster of setae projecting backwards from anterior margin just laterad midline, a few longer setae projecting anterad from posterior edge of impression; depression shallowly continued in anterolateral, glabrous depressions; extreme sides of pronotal disk with irregularly ovoid, very shallow, glabrous depressions, their outer / lower edges forming lateral pronotal margin; each elytron with four basal fovea, the lateral pair in a common depression, barely distinguishable; no subhumeral fovea or stria; flight wings present; prosternum very short, with anterior prosternal foveae at anterior corner of hypomeron; legs simple, mesotrochanter slightly dentate at middle of posterior edge; male metaventrite setose posteriorly between metacoxae; male last abdominal ventrite densely setose along distal margin, depressed on either side of a thin, prominent median denticle; terminal male tergite with apical margin widened, flattened, and densely setose. Aedeagus (Fig. 6 L View Figure 6 ) slender, base slightly bulbous, with small, oval basal foramen; parameres free for basal 1 / 4, then fused with median lobe just beyond foramen; median lobe slightly constricted beyond paramere fusion, dorsally arched, with long median part a flattened cylinder, a shorter, slightly widening dorsal process over it, just shorter, and lateral ‘ wings’ with long, curved, articulated rods recurving toward middle at apices. TL 1.6–1.67 mm, EW 0.33–0.36 mm.
