( Figs 183 C, D , 185 , 187 B )

Diagnosis. Apterous ♀ of Gonatopus with palpal formula 5/3; pronotum crossed by strong transverse furrow; me- soscutum without two lateral pointed apophyses; meso-metapleural suture distinct and complete; metapectal-propo- deal disc without strong median longitudinal furrow; enlarged claw ( Fig. 187B with apex tapering, one big subdistal tooth and one row of lamellae (subdistal tooth located very close to more distal lamella).

Description. ♀ ( Fig. 185 ). Apterous; body length 2.8 mm. Head brown, except mandible and clypeus testa- ceous; antenna brown; mesosoma, metasoma and legs brown. Antenna clavate; antennomeres in following proportions: 7:5:15:10:8:6:6:5:5:7. Head excavated, dull, granulate; frontal line complete; occipital carina absent; POL = 2; OL = 2; OOL = 10; greatest breadth of lateral ocelli about as long as OL. Palpal formula 5/3. Pronotum shiny, crossed by strong transverse impression, unsculptured, except many longitudinal striae on disc and lateral regions. Mesoscutum dull, sculptured by many longitudinal striae, laterally without two pointed apophyses ( Fig. 183C ). Metanotum rugose, deeply excavated behind mesoscutellum ( Fig. 183D ), with sides protruding; lateral protrusions slightly pointed ( Fig. 183C ). Metapectal-propodeal disc dull, sculptured by many slight longitudinal striae; propodeal declivity, mesopleuron and metapleuron transversely striate. Meso-metapleural suture distinct and complete. Protarsomeres in following proportions: 14:3:6:14:23. Enlarged claw ( Fig. 187B with one big subdistal tooth and one row of seven lamellae (subdistal tooth located very close to more distal lamella).
