Diagnosis. Apterous ♀ of Gonatopus with palpal formula 5/3; mesosoma black; pronotum crossed by strong trans- verse furrow; mesoscutum with two strong lateral pointed apophyses; meso-metapleural suture distinct and com- plete; metanotum without lateral protrusions; metapectal-propodeal disc fusiform, without strong median longitudi- nal furrow; enlarged claw ( Fig. 182A ) with one large subdistal tooth, one row of lamellae, apex tapering.

Description. ♀ ( Fig. 181 ). Apterous; body length 3.7 mm. Head black, except mandible, lateral surfaces of clypeus and part of malar space (short stripe along orbits) testaceous; antenna brown, except antennomeres 7–10 testaceous; mesosoma black; metasoma and legs brown. Antenna clavate; antennomeres in following proportions: 10:6:15:10:8:7:5:5:5:8. Head excavated, shiny, unsculptured, partly slightly granulate; frontal line complete; oc- cipital carina absent; POL = 1; OL = 2; OOL = 9. Palpal formula 5/3. Pronotum shiny, unsculptured, crossed by strong transverse furrow. Mesoscutum with two lateral pointed apophyses, situated on sides of anterior margin of mesoscutellum ( Fig. 180E ). Mesoscutellum sloping anteriorly. Metanotum short, excavated behind mesoscutellum ( Fig. 180F ), with sides rounded ( Fig. 180E ). Metapectal-propodeal disc fusiform, shiny, unsculptured; propodeal declivity transversely striate. Mesopleuron and metapleuron transversely striate. Meso-metapleural suture distinct and complete, step shaped. Protarsomeres in following proportions: 15:3:5:15:26. Enlarged claw ( Fig. 182A ) with one large subdistal tooth and one row of seven lamellae and one bristle. Protarsomere 5 ( Fig. 182A ) with two rows of 9 + 13 lamellae; apex with about 20 lamellae. Tibial spurs 1/0/1.
