Male
Body length.

.
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.

Clinocentrus nigripectus
Enderlein.
(A) Forewing; (B) hindwing; (C) head in lateral view; (D) head in anterior view; (E) head in dorsal view; (F) metasomal terga I to III in dorsal view.
Head.
Almost entirely smooth, sligthly higher than long and 1.3 times as high as wide (
Figure 3C–E
), 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
), 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
); 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
) 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
) 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
), 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
). Terga II and III uniformly covered with setae. Metasomal terga beyond tergum III not distinctly desclerotized as mentioned for
C. roigi
and
C. mamull
.
Female
Unknown.
Distribution
Known only from the State of
Santa Catarina
,
Brazil
.
Biology
Unknown.
Comments
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
.
