( Figs 190 , 192G, H , 194A )

Diagnosis. Apterous ♀ of Gonatopus with palpal formula 6/3; head excavated; pronotum crossed by strong transverse furrow; metapectal-propodeal disc and propodeal declivity totally ferruginous; metapectal-propodeal disc sculptured by irregular longitudinal keels; protarsomere 1 longer than 4; enlarged claw ( Fig. 194A ) with one large subdistal tooth and one row of lamellae.

Description. ♀ ( Fig. 190 ). Apterous; body length 3.0 mm. Ferruginous, except petiole black and metasoma brown. Antenna clavate; antennomeres in following proportions: 11:7:14:9:7:5:5:4:4:7. Head excavated, shiny, granulate, except two large unsculptured areas on sides of frontal line; frontal line complete; occipital carina absent; temple distinct; POL = 1; OL = 3; OOL = 9; greatest breadth of lateral ocelli shorter than OL (2:3). Palpal formula 6/3. Pronotum shiny, with many slight longitudinal striae on disc and lateral regions; rest of surface unsculptured; pronotum crossed by strong transverse furrow. Mesoscutum shiny, sculptured with some longitudinal striae and with two strong, pointed apophyses laterally ( Fig. 192G ). Mesoscutellum shiny, smooth, sloping strongly anteriorly. Metanotum deeply excavated behind mesoscutellum ( Fig. 192H ), flat, strongly rugose, with sides protruding (lat- eral protrusions slightly pointed ( Fig. 192G )). Metapectal-propodeal disc shiny, strongly sculptured by numerous irregular longitudinal keels and partly rugose; propodeal declivity transversely striate. Mesopleuron partly granulate and partly transversely striate. Metapleuron dull, transversely striate. Meso-metapleural suture distinct and com- plete, step shaped. Protarsomeres in following proportions: 17:3:5:14:22. Enlarged claw ( Fig. 194A ) with one large subdistal tooth and one row of five lamellae. Protarsomere 5 ( Fig. 194A ) with two rows of 14 lamellae; apex with at least 20 lamellae. Tibial spurs 1/0/1.
