Clinocentrus nigripectus Enderlein  

( Figure 3 View Figure 3 ) Clinocentrus nigripectus Enderlein, 1920: 146   (type male, Museum and Institute of Zoology, Warsaw; examined)  


Body length. 4.5 mm.

Body colour. Mostly dark brown; head, lateral areas of pronotum, metapleuron, basal area of tergum I and legs except tarsi lighter; wings hyaline, veins brown.

Head. Almost entirely smooth, sligthly higher than long and 1.3 times as high as wide ( Figure 3C–E View Figure 3 ), occipital carina complete, reaching hypostomal carina; eye medium sized, 1.3 times higher than wide; temple 0.7 times as long as eye width, eye height 3.3 times longer than malar space; malar space about as long as basal width of mandible ( Figure 3C View Figure 3 ), mandibles slender; hypoclypeal depression slightly wider than basal width of mandible, ocello–ocular distance 2.0 times the diameter of lateral ocellus and 1.6 times posterior ocellar line ( Figure 3E View Figure 3 ); antenna with 35 segments, first flagellar segment 4.3 times longer than wide and 1.3 times longer than second flagellar segment.

Mesosoma   . 2.1 times longer than wide and slightly higher than wide. Mesoscutum smooth, notauli present and complete, scrobiculate, enclosing a rugulose median area posteriorly; prescutellar depression rugulose, scutellar disc subtriangular and mostly smooth. Mesopleuron mostly smooth, except for subalar depression and sternaulus which are scrobiculate. Metapleuron rugulose. Propodeum rugose–areolate without acinose–coriaceous basal areas.

Wings. Forewing ( Figure 3A View Figure 3 ) with marginal cell not shortened, first submarginal 2.1 times as long as broad, RS + Mb two-thirds the length of 2RS; r 0.6 times the length of 3RSa. Hindwing ( Figure 3B View Figure 3 ) with vein M + CU slightly longer than 1M; junction between veins 1A and cu-a rounded.

Metasoma. Tergum I about 1.2 times longer than wide ( Figure 3F View Figure 3 ), without spiracular tubercules, striate, with two more clearly defined anterior carinae converging posteriorly and enclosing a trianglar smooth area. Tergum II striate, striation parallel not convergent on median anterior area. Tergum III mostly smooth, with very weak transverse apical striations ( Figure 3F View Figure 3 ). Terga II and III uniformly covered with setae. Metasomal terga beyond tergum III not distinctly desclerotized as mentioned for C. roigi   and C. mamull   .




Known only from the State of Santa Catarina, Brazil.




Clinocentrus nigripectus   was described based on a single male specimen from an unknown locality in Santa Catarina, Brazil. The study of the holotype male allows the distinction of this species from the other South American species of Clinocentrus   based on body colour, wing pigmentation, mandible morphology, number of antennal segments and metasomal setae and sculpture   .
