Dilobocondyla gaoyureni Bharti & Kumar, 2013: 32, figs 5–7. (Holotype worker images examined, AntWeb, ANTWEB1008026, photoed by H. Bharti).
Diagnosis. The species can be distinguished from D. fouqueti by the acutely angled posterior head corners, relatively lower petiolar dorsum, distinct micro-reticulations on the gaster, and the lighter body color. It also can be distinguished from D. rufida by the acutely angled posterior head corners, relatively longer petiole, and the lighter body color.
Material examined. 2 workers, CHINA: Hainan, Wuzhishan, Hudiemuchang Scenic Spots, 18.86°N, 108.67°E, 715 m, 5.IV.2016, leg. Zhilin Chen, No. G 160335.
Description. Worker (Figs 4–6). TL 4.5–4.6, HL 1.03–1.04, HW 0.99, CI 95–96, SL 0.64–0.65, SI 64–65, ED 0.25, PW 0.76–0.77, MSL 1.43–1.45, PL 0.52, PH 0.27, DPW 0.25, LPI 52, DPI 48 (n = 2).
In full-face view, head nearly rectangular, a little longer than width, posterior margin slightly concave medially, posterior corners acutely angled, lateral margins weakly convex. Mandible triangular, masticatory margin 6-toothed, with large apical and preapical teeth, and 4 additional small teeth. Clypeus without longitudinal median carina, anterior margin notched in the center. Frontal carinae conspicuous, curved outward, reaching to 3/4 of head length. Antennae 12-segmented, with distinct 3-segmented club, scapes reaching to 3/4 of head length. Eyes large and convex.
In lateral view, promesonotal dome convex, a little higher than propodeum, promesonotal suture absent. Metanotal groove moderately impressed. Dorsum of propodeum weakly convex, forming a rounded corner with declivity. Propodeal lobes well developed, with rounded apices. Petiole relatively longer, 2 times as long as high, dorsal margin moderately convex, anteroventral corner minutely toothed. Postpetiole roughly triangular, incrassate posteriorly, dorsum strongly convex, higher than petiole. Gaster ovate.
In dorsal view, pronotum trapezoidal, narrowed posteriorly, humeral corner forming a blunt tooth. Promesonotal suture absent. Mesonotum short and narrower than pronotum. Metanotal groove indistinct. Propodeum roughly rectangular and narrower than pronotum. Petiole narrow and rectangular, weakly widened posteriorly, lateral margins straight. Postpetiole broader than petiole and widening posteriorly, with convex lateral margins. Gaster ovate.
Mandibles longitudinally striate. Clypeus and vertex of head longitudinally rugose, the rest of head rugose-reticulate. Mesosoma, petiole and postpetiole rugose-reticulate, reticulation became weaker on mesopleura and metapleura. Gaster distinctly micro-reticulate and dull, first gastral tergite with abundant basal costulae. Whole body surface with abundant erect to suberect hairs. Head and legs brown; scapes, mesosoma and waist segments brownish yellow; gaster blackish brown.
Distribution. China (Guangdong, Hainan).
