Clinocentrus roigi   sp. nov.

( Figure 2 View Figure 2 )

Female

Body length. 3.8–4.0 mm.

Body colour. Mostly yellow; antenna, apex of mandibles and ovipositor sheaths black; mesopleuron with distinct well-defined black ventral area; lateral lobes of mesoscutum with black or dark brown markings; metasomal terga uniformly yellow; hind tibia dark brown apically, tarsi dark brown; wings infuscate basally, veins dark brown to black.

Head. Almost entirely smooth, as high as long and 1.3–1.7 times higher than wide ( Figure 2C–E View Figure 2 ); occipital carina complete, reaching hypostomal carina; eye large, 1.2–1.3 times higher than wide; temple 0.5 times as long as eye width, eye height 7.8–8.0 times longer than malar space; malar space one-half to one-third the basal width of mandible ( Figure 2C View Figure 2 ); mandibles subtriangular in lateral view; hypoclypeal depression slightly wider than basal width of mandible; ocello-ocular distance 1.5–3.0 times the diameter of lateral ocellus and 1.2–1.7 times posterior ocellar line ( Figure 2E View Figure 2 ); antenna with 30 to 32 segments, first flagellar segment 2.5 times longer than wide and only slightly longer than second flagellar segment.

Mesosoma   . 2.0 to 2.1 times longer than wide and slightly higher than wide. Mesoscutum smooth, notauli present and complete, scrobiculate, enclosing a rugulose–striate median area posteriorly; prescutellar depression rugulose, scutellar disc subtriangular and smooth. Mesopleuron mostly smooth, except for subalar depression and sternaulus which are scrobiculate, sternaulus weakly sinuate. Metapleuron rugulose. Propodeum mostly rugose areolate but with two distinct acinose–coriaceous basal areas.

Wings. Forewing ( Figure 2A View Figure 2 ) with marginal cell elongate, first submarginal cell 2.0 times as long as broad or longer, RS + Mb about two-thirds the length of 2RS; r about two-thirds the length of 3RSa. Hindwing ( Figure 2B View Figure 2 ) with vein M + CU slightly longer than 1M; junction between veins 1A and cu-a broadly rounded and desclerotized.

Metasoma. Tergum I 1.0–1.1 times longer than wide ( Figure 2F View Figure 2 ), without spiracular tubercules, striate, with two more clearly defined anterior carinae converging posteriorly and enclosing a triangular anterior smooth area. Tergum II striate, striations slightly convergent on median anterior area. Tergum III vith transverse and broadly curved striations ( Figure 2F View Figure 2 ). Terga II and III devoid of setae anteriorly and medially. Metasomal terga beyond tergum III weakly sclerotized and collapsed in air-dried specimens. Ovipositor sheaths about 0.4 times the total body length.

Male

Essentially as in female, slightly smaller and lighter in body colour.

Distribution

Eastern Argentina. This species was collected in one locality at the Delta of the Parana river.

Biology

Unknown.

Etymology

This species is named after the hymenopterist Arturo Roig-Alsina, for his support and advice during my work.
