Diagnosis. Apterous ♀ of Gonatopus with palpal formula 6/3; pronotum crossed by strong transverse furrow; metanotum about coplanar to mesoscutellum ( Fig. 192B ); metapectal-propodeal disc brown-black, with disc slightly humped ( Fig. 189A ); enlarged claw with apex very broad ( Fig. 191A ) and one big subdistal tooth; protarsomere 5 with one short row of lamellae ( Fig. 191A ).

Description. ♀ ( Figs 186D , 188 , 189A ). Apterous; body length 3.7 mm. Head brown-black, except mandible testaceous and one ferruginous longitudinal stripe between antennal toruli; antenna brown (antennomere 10 missing); mesosoma brown-black, except mesoscutum testaceous; metasoma brown; legs brown, except tarsi, part of procoxa and protrochanter testaceous.Antenna clavate; antennomeres in following proportions: 11:6:25:16:13:12:9:8:7 (antennomere 10 missing in holotype). Head ( Fig. 188D ) excavated, dull, granulate; frontal line complete; occipital carina absent; POL = 1; OL = 2.5; OOL = 9; greatest breadth of lateral ocelli longer than POL (2:1). Palpal for-mula 6/3. Pronotum shiny, finely punctate, unsculptured among punctures, crossed by strong transverse furrow. Mesoscutum shiny, unsculptured, with two strong lateral pointed apophyses ( Figs 188B , 192A ). Mesoscutellum shiny, flat. Metanotum about coplanar to mesoscutellum ( Figs 188C , 192B ). Metapectal-propodeal disc swollen, shiny, finely punctate, unsculptured among punctures; propodeal declivity transversely striate. Mesopleuron shiny, unsculptured. Metapleuron transversely striate. Meso-metapleural suture distinct and complete. Protarsomeres in following proportions: 19:3:7:20:34. Enlarged claw ( Fig. 191A ) with apex very broad, one big subdistal tooth and one row of eight lamellae + two bristles. Protarsomere 5 ( Fig. 191A ) with one row of 10 lamellae situated in distal half of protarsomere 5; apex with at least 25 lamellae. Tibial spurs 1/0/1.
