Dilobocondyla fouqueti Santschi, 1910 View in CoL

Dilobocondyla fouqueti Santschi, 1910: 283 View in CoL . (Syntype worker images examined, AntWeb, CASENT0912885 , photoed by Z. Lieberman).

Dilobocondyla fouqueti var. lighti Wheeler, W.M., 1927: 6 . Synonymized by Wang & Wu, 1992: 562. (not examined).

Diagnosis. The species can be distinguished from other species of Dilobocondyla by the imperceptible hexagonal microreticulations. Its micro-reticulations on gasteral dorsum are also much more subtiler than other species, which can be easily observed.

Material examined. 1 worker, CHINA: Hainan, Wuzhishan, Hudiemuchang Scenic Spots , 18.86°N, 108.67°E, 715 m, 5.IV.2016, leg. Zhilin Chen, No. G 160376; GoogleMaps 2 workers, CHINA: Hainan, Wuzhishan, Redaiyulin Scenic Spots , 18.87°N, 108.69°E, 850 m, 5.IV.2016, leg. Zhilin Chen, No. G 160302 GoogleMaps .

Description. Worker ( Figs 1–3 View Figures 1−6 ). TL 5.6–5.7, HL 1.28–1.31, HW 1.27–1.28, CI 99–100, SL 0.81–0.83, SI 64–65, ED 0.24–0.26, PW 0.86–0.87, MSL 1.73–1.75, PL 0.54–0.55, PH 0.31–0.34, DPW 0.27–0.28, LPI 57–58, DPI 50–52 (n = 3).

In full-face view, head nearly quadrate, posterior margin concave medially, posterior corners bluntly angled, lateral margins weakly convex. Mandibles triangular, masticatory margin 6-toothed, with large apical and preapical teeth, and 4 additional small teeth. Clypeus flat, without median longitudinal 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; apices of scapes reaching to 3/4 of head length. Eyes large and convex.

In lateral view, promesonotal dome weakly convex, a little higher than propodeum. Metanotal groove weakly impressed. Dorsum of propodeum slightly convex, posterodorsal corner rounded. Propodeal lobes well developed, with rounded apices. Petiole relatively longer, 1.7 times as long as high, dorsal margin strongly convex, anteroventral corner toothed. Postpetiole roughly triangular, incrassate posteriorly, dorsum strongly convex, higher than petiole. Gaster ovate.

In dorsal view, pronotum roughly trapezoidal and narrowed posteriorly, humeral corner forming a small pointed denticle. Promesonotal suture absent. Mesonotum short and narrower than pronotum. Metanotal groove indistinct. Propodeum roughly rectangular and narrower than pronotum. Petiole narrow and rectangular, with 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 reduced on mesopleura and metapleura. Dorsum of gaster finely micro-reticulate and shining, first gastral tergite with sparse basal costulae. Whole body surface with abundant erect to suberect hairs. Head and gaster darkish brown to black, mesosoma and waist segments yellowish brown to reddish brown, scapes yellowish brown, legs blackish brown.
