Diagnosis. Apterous ♀ of Gonatopus with palpal formula 6/3; temple without sharp carina; mesosoma black; pro- notum crossed by strong transverse furrow; mesoscutum less than twice as long as broad, laterally with two strong pointed apophyses; mesopleuron without lateral pointed prominence; metanotum deeply excavated behind mesos- cutellum; meso-metapleural suture distinct and complete; metapectal-propodeal disc without strong median furrow; protarsomere 1 as long as 4; enlarged claw ( Fig. 234B View FIGURE 234 ) long, straight and slender, with one small subapical tooth and one row of peg-like setae; subapical tooth of enlarged claw situated very near apex ( Fig. 234B View FIGURE 234 ).
