Anillinus acutipennis Sokolov & Reddell 2014

Medium-sized for genus (SBL range 1.62–1.84 mm, mean 1.74±0.116 mm, n=3). Habitus. Body form (Fig. 5E) subdepressed, subparallel, markedly elongate (WE/SBL 0.33±0.009), head large for genus compared to pronotum (WH/WPm 0.80±0.006), pronotum wide in comparison to elytra (WPm/WE 0.88±0.013). Color. Body rufotestaceous, appendages testaceous. Microsculpture. Distinct over all dorsal surfaces of head, pronotum and elytra, with slightly transverse polygonal meshes of more or less scaly appearance on elytra. Head. Labium (Fig. 3B). Mental tooth present; mentum and submentum separated by suture. Glossal sclerite with distinct paraglossae laterally and with two setae apically. Prothorax. Pronotum (Fig. 2F) relatively long (LP/LE 0.42±0.016) and markedly elongated (WPm/LP 1.23±0.080), with lateral margins shallowly sinuate and moderately constricted posteriorly (WPm/WPp 1.28±0.020). Anterior angles indistinct, posterior angles nearly rectangular (90–100°). Width between anterior and posterior angles of approximately equal length (WPa/WPp 1.02±0.024). Basal margin straight. Elytra (Fig. 2J). Widely depressed along suture, comparatively short (LE/SBL 0.57±0.004) and narrow for genus (WE/LE 0.59±0.020), with traces of 4-5 striae. Humeri distinct, rounded, in outline forming obtuse angle with longitudinal axis of body. Lateral margins subparallel, slightly divergent at basal fourth, evenly rounded to apex in apical fourth, without subapical sinuation. Vestiture of elytra short (less than one-third length of discal setae). Apex of elytron deeply emarginate, the notch with a distinct spine laterally. Male unknown. Female genitalia. Spermatheca with distal part of cornu only slightly dilated, gradually tapered to proximal part. Nodulus short, ramus undifferentiated (Fig. 7G).
