Material examined. Specimens were examined from the following collections:
Locality information for holotypes of the species described here is verbatim. Text as it appears on the labels is contained in quotation marks. The text for each label is delimited by double forward slash marks.
Images. Habitus photos of beetles were taken as image stacks that were aligned and assembled with Helicon Focus version 5.3 and image files were edited to enhance clarity using standard image editing software.
Dissection and measurements. Male genitalia were prepared using the same methods as
With a combination of typical abacetine characters such as clearly defined frontal impressions on the head; deeply impressed, linear basolateral pronotal impressions; no angular base of stria 1 on elytra; setose puncture at the base of elytral stria 2; well-developed elytral plica; metacoxal sulcus sinuate; abdominal ventrites without transverse sulci; ostium of aedeagus dorsal; and aedeagus left side dorsal in repose. Recognizable from other abacetine genera that share the character states listed above by the combination of deep post-ocular sulcus (Fig.
Small size beetles (3.8–4.3 mm), castaneous or darker, nearly piceous colored, parallel sided, somewhat convex body form; apical segment of labial palpi elongate and fusiform. Mentum narrow triangular, shallowly emarginate; epilobes long and narrow, not prominent; median tooth prominent and entire, not reaching tips of lobes, mentum paramedial pits absent; paraglossae short, glabrous; submentum narrow, posteriorly sculpted; antennae of moderate length, somewhat thickly filiform, three basal segments glabrous except for apical ring of setae; postocular orbits moderately pronounced, with deep post-ocular sulcus (Fig.
