Tiferonia Darlington, 1962: 560.

Type species.

Tiferonia parva Darlington, 1962: 562, by original designation.

Generic diagnosis.

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. 1 View Figure 1 ), smooth elytral margins, and lack of elytral discal setae.

Genus characteristics.

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. 1 View Figure 1 ). Elytra free, lateral margin smooth; border entire across base; parascutellar stria present, joined to stria 1; 13-15 umbilicate setae in stria 8; hind wings fully developed; humeri obtusely angled with very small, usually sharp denticle; anterior tarsi of male with three basal segments narrowly dilated and squamose beneath. Aedeagus (Fig. 2 View Figures 2, 3 ) with orifice on dorsum; parameres conchoid, the right smaller than the left.
