( Figs 235View FIGURE 235 GView FIGURE 235, 236View FIGURE 236 AView FIGURE 236, 237View FIGURE 237, 239View FIGURE 239 D, EView FIGURE 239)

Diagnosis. Apterous ♀ of Gonatopus  with palpal formula 6/3; temple without sharp carina; mesosoma black; pronotum crossed by strong transverse furrow; mesoscutum less than twice as long as broad, with two lateral pointed apophyses; mesopleuron without lateral pointed apophyses; metanotum deeply excavated behind mesoscutellum, with sides rounded (metapectal-propodeal disc fusiform); meso-metapleural suture distinct and complete; metapectal-propodeal disc without strong median furrow, only with slight track of median furrow, sculptured by some longitudinal keels; protarsomere 1 slightly shorter than 4; enlarged claw ( Figs 235GView FIGURE 235, 236AView FIGURE 236) with one small subapical tooth, situated very far from apex, and proximal peg-like setae.

Description. ♀ ( Fig. 237View FIGURE 237). Apterous; body length 2.5–3.0 mm. Head black, except mandible, clypeus and malar space (with stripe along orbits) testaceous; antenna brown, except ventral side of antennomere 1 whitish; mesosoma black; metasoma and legs brown. Paratypes with head black, except mandible, clypeus and anterior surface of frons testaceous; mesosoma black, except part of prothorax, part of mesoscutum and metanotum testaceous-brown. Head excavated, dull, granulate; frontal line complete; occipital carina absent; POL = 1.5; OL = 2; OOL = 8. Palpal formu- la 6/3. Pronotum crossed by strong transverse furrow, shiny, slightly granulate (unsculptured in paratypes). Mesos- cutum shiny, with some longitudinal keels, with two lateral pointed apophyses ( Fig. 239DView FIGURE 239). Mesoscutellum sloping anteriorly. Metanotum excavated behind mesoscutellum ( Fig. 239EView FIGURE 239), not protruding laterally. Metapectal-propodeal disc fusiform, dull, granulate, sculptured by some longitudinal irregular keels, with slight median longitudinal fur- row; propodeal declivity strongly transversely striate. Paratypes with metapectal-propodeal disc shiny, sculptured by longitudinal striae, unsculptured among striae. Mesopleuron slightly granulate, not transversely striate. Meta- pleuron strongly transversely striate. Meso-metapleural suture distinct and complete, step shaped. Protarsomeres in following proportions: 12:2.5:4:5:14:22. Enlarged claw ( Figs 235GView FIGURE 235, 236AView FIGURE 236) with one small subapical tooth and two proximal peg-like setae + 1–2 bristles. Protarsomere 5 ( Figs 235GView FIGURE 235, 236AView FIGURE 236) with inner side proximally not serrate and two rows of 3–4 (proximal) + 17–18 lamellae; apex with about 15 lamellae. Tibial spurs 1/0/1.
