Paratrigonoides , gen. nov.

Type species; Paratrigonoides mayri sp. n.

Diagnosis. Worker. a— Body length between 4.5 and 4.7 mm. b— integument mattemicroreticulate on head and thorax; metapostnotum alveolate. c— Body dark ferrugineous except vestiture and markings described below; mesoscutum black; wing membrane hyaline. d— Yellow markings pronounced on head, thorax and base of all tibiae. On the head, yellow markings on paraocular areas, clypeus, supraclypeal area and frons; frons with oblong mark on each side of median line and smaller mark anterior to lateral ocellus ( Fig. 1 ). On the thorax, yellow markings as follows: a transverse stripe on pronotum, entire pronotal lobe, one stripe each side of mesoscutum, axilla and distal margin of scutellum. e— Vestiture: erect hairs on body uniformly pale­whitish, slightly more yellowish on tarsi; in addition, a fine silvery gray micropilosity, branched, decumbent, covering face and mesoscutum; erect hairs lacking on lower half of face; row of robust setae, branched at apices, along preoccipital lamella, on upper part of occiput ( Fig. 2 ); metapostnotum glabrous; setae on abdominal sterna branched; f— Head ca. 1.09 x wider than long, slightly wider than thorax; maximum interorbital distance slightly greater than length of eye; inner orbit of eye somewhat convergent below; superior alveolar tangent slightly below middle of face; vertex rounded, not forming post­ocellar carina; malar space very short, approximately ¼ diameter of third flagellomere; preoccipital ridge having fine lamella on the upper part, curving forward ( Fig. 2 ); side rounded; gena, seen from side, narrower than compound eye. g— Clypeus ca. 1.96 x wider than long, convex; epistomal suture, between subantennal sutures a widely open V;
