Clinocentrus mamull sp. nov.

( Figure 1 )

Female

Body length. 3.2–3.8 mm.

Body colour. Mostly honey yellow, antenna, apex of mandibles and ovipositor sheaths black; lateral lobes of mesoscutum and axillar depression usually with black or dark brown markings, sometimes uniformly yellow; metasomal tergum III always brown, often terga II and IV also brownish; hind tibia gradually darkened towards apex; tarsi brownish; wings hyaline, veins brown.

Head. Almost entirely smooth, as high as it is long and 1.4–1.7 times higher than wide ( Figure 1C–E ); occipital carina complete, reaching hypostomal carina; eye large, 1.4–1.8 times higher than wide; temple 0.3–0.4 times as long as eye width, eye height about 8.0 times longer than malar space; malar space one-half to one-third basal width of mandible ( Figure 1C ); mandibles subtriangular in lateral view; hypoclypeal depression slightly wider than basal width of mandible; ocello–ocular distance 1.5–2.3 times the diameter of lateral ocellus and 1.5–1.7 times posterior ocellar line ( Figure 1E ); antenna with 28–30 segments, first flagellar segment 3.0 times longer than wide and only slightly longer than second flagellar segment.

Mesosoma . 1.8–2.0 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 1A ) with marginal cell elongate; first submarginal cell 2.0 times as long as broad or longer; RS + Mb one-half to more than two-thirds the length of 2RS; r about two-thirds the length of 3Rsa. Hindwing ( Figure 1B ) 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 1F ), without spiracular tubercules, striate, with two more clearly defined anterior carinae converging posteriorly and enclosing a triangular smooth area. Tergum II striate, striations slightly convergent on median anterior area. Tergum III vith transverse and broadly curved striations ( Figure 1F ). Terga II and III mostly devoid of setae anteriorly and medially. Metasomal terga beyond tergum III weakly sclerotized and collapsed in airdried specimens. Ovipositor sheaths about 0.4 times the total body length.

Male

Unknown.

Distribution

Central Argentina. This species was always collected in the Espinal biogeographical province, as defined by Cabrera and Willink (1973), in semiarid forests dominated by the legume genus Prosopis .

Biology

Unknown.

Etymology

The specific epithet derives from the native word “ mamüll ”, meaning wood or stick, which is also used to describe animal or plant species from the deciduous semiarid forests in which this species was collected, meaning “from the monte ”.
