Hingstoniella: Newton & Chandler, 1989: 37 (catalog); Yin, Li & Zhao, 2011: 390 (diagnosis, redescription, illustrations).
Diagnosis: Head triangular; frontal rostrum low; with punctiform vertexal foveae; antennomeres XI elongate and conical. Pronotum transversely octagonal, with only punctiform lateral antebasal foveae; lacking antebasal spines. Elytra each with one large basal fovea and shallow discal stria. Abdomen with lateral margins of tergite IV edged by marginal carinae; tergite IV longest.
Redescription: General body form robust; Length 3.09- 3.56 mm. Head triangular (Fig. 1 A); with low frontal rostrum, antennal tubercles low; vertexal foveae small and punctiform, connected by indistinct U-shaped vertexal sulcus; antennae with 11 antennomeres, clubs formed by apical three antennomeres, antennomeres XI elongate and conical; ocular-mandibular carinae faint; eyes reniform (Fig. 1 B); maxillary palpi with palpomeres III transverse and triangular, IV fusiform; with gular foveae merged into single opening (Fig. 1 C). Pronotum (Fig. 1 D) transversely octagonal; lateral antebasal foveae punctiform, lacking median antebasal fovea and antebasal spines; disc only slightly convex; lacking basolateral foveae; lacking paranotal carinae; lateral procoxal foveae (Fig. 1 E) present. Each elytron (Fig. 1 F) with one large basal fovea, discal striae shallow, sutural striae complete; lacking subhumeral foveae, marginal stria present from basal one-fourth toward posterior margin; lateroapical notch indistinct. Thorax (Fig. 2 A) with small median and lateral mesoventral foveae; with lateral mesocoxal foveae; prepectal foveae present; lateral metaventral foveae punctiform, metacoxae narrowly separated; posterior margin with narrow median notch. Abdomen (Fig. 2 B-D) has tergites IV-VI (first to third visible tergites) with marginal carinae extending through tergal length; tergite IV longest, V-VII slightly shorter and subequal in length; tergite IV with basolateral foveae at lateral ends of sulcus, lacking mediobasal foveae and discal carinae, V-VII each with one pair of basolateral foveae. Sternite IV (second visible ventrite) twice length of V at midlength, with one pair of mediobasal foveae and three pairs of basolateral foveae, lacking basal sulcus, V-VII lacking foveae. Legs short, second and third tarsomeres subequal in length.
Male (Fig. 3 A-B) with vertex modified. Aedeagus with paramere fused to median lobe to form elongate ventral lobe; articulated dorsal lobe present; basal capsule with strongly constricted base.
