D e s c r i p t i o n:

Body length 8 mm. Flagellum long and slender, bristle-shaped, with 33 flagellomeres, all flagellomeres much longer than wide, first flagellomere (without anellus) about 5.0 times as long as wide. First and seconde flagellomeres together 1.1 times as long as the eye. Temples strongly narrowd behind the eyes. Ocelli moderately large, the lateral ones about 1.0 times as long as their distance to the eyes, frons with fine transverse rugulae above, its lower part smooth, face with longitudinal puncture-striation, matte, clypeus with dense puncture and almost shining. Malar space 1,0 times as long as the width of the mandibular base. Hypostomal carina not elevated.

Mesoscutum densely punctured, anterior part of middle field with granulation, otherwise smooth, mesopleura and metapleura very densely punctured, more or less shining, coxal carina distinct. Scutellum distinctly elevated, slightly wider than long, with strong lateral carinae to the apex. Propodeum punctured, without apophyses, its spiracles long-oval (index about 3). Area superomedia hexagonal, a little wider than long, with some coarse rugae, costulae indistinct, in the middle, area posteromedia with coarse irregular rugae. Coxae with dense puncture, hind coxa without scopa. Hind femur slender, about 5.3 times as long as high, with superficial dense puncture.

Metasoma amblypygous, postpetiole only slightly widened, with indistinct dorsal carinae, median field superficially rugulose, shining. Second tergite long, 1.25 times as long as wide, gastrocoeli slightly impressed, thyridia large, oblique, each about 2.0 times as wide as their interval, their interval narrower than the median field of postpetiolus, second and third tergites densely and superficially punctured, matte, following tergites densely granulated and more or less matte.

Colour reddish-brown and black. Ivory are stripes on flagellomeres 9-12, small spots on clypeus sides, facial and frontal orbits, stripe on outer orbits, collare and upper margin of pronotum, subalar ridge and small spot on coxa I. Reddish-brown are head except a blackish central spot on clypeus and blackish occiput, mesoscutum, upper half of pronotum, mesopleura except blackish front part anterior to epicnemia, mesosternum, scutellum and postscutellum, postpetiole and alle following tergites, sternites and legs including coxae.

T a x o n o m i c a l r e m a r k This new taxon runs to couplet 8: Platylabus charlottae HEINRICH in the key published by HEINRICH (1974: 109-112), but differs by its long second metasomal tergite and the coloration.
