Material examined

Holotype (♀). “Prov. Valdivia, Valdivia – CHILE 13.XI.80 E. Krahmer ” ( BMNH).

Female: whole insect, see Figure 9 ; fore wing length 16 mm. Antenna with 36 flagellomeres. Tergite I about 2.3 times as long as apically wide, tergite II 1.15 times as long as wide. Head and mesosoma with fine, regular punctation, except clypeus coriaceous. Mandible basally, medially coriaceous and medially strongly punctate, apically smooth. Head with background sculpture finely coriaceous, mesosoma lacking background sculpture. Propleurum with some transverse striation on lower part. Pronotum with striation and aciculation anteriorly / ventrally, anterior edge strongly punctate. Punctation strongest on mesosternum and epicnemium. Rear part of mesopleurum impunctate, propodeum (except metapleurum) impunctate. Coxae and femora regularly, finely punctate; legs with fine micro-reticulation. Metasoma with tergite I smooth but with some postero-lateral rugosity and anterior third of tergite II with rugosity. Hind edges of tergites I and II with shiny, transverse band, sculpture otherwise “satiny”. Metasoma progressively shinier posteriorly. Other characters as in generic description.

Colour: black, white in the following areas: 17.5 sub-apical flagellomeres (apical flagellomere black), tarsomere IV of fore leg, tarsomeres III–IV of mid leg, tarsomeres II–V of hind leg (except V black apically and I off-white apically). Fore femur with pale brown area apically on anterior face; mandible with brown medio-dorsal patch. Sternites mostly dark brown, sternites II–IV with antero-lateral oval, pale patches; membranous areas pale. Wings strongly infuscate, brown.

Etymology

The specific name is derived from the Latin noun for rain or cloud, nimbus , referring to its dark wings, and is to be treated as a noun in apposition.

Nothing is known of the biology of Valdiviglypta nimbus and we have no information on the habitat in which the one known specimen was collected.
