Cerritulus forticrura sp. nov.

( Figs 1 A–G).

Type material. Holotype. Female , “ Guyane, Montagne des Chevaux, 17.V.2014, piège à vitre, SEAG leg” ( IB- UNAM).

Description. Holotype. Female. Body length 4.0 mm; fore wing length 3.1 mm.

Head behind eyes weakly roundly narrowed, temple 0.7 × as long as transverse diameter of eye (dorsal view). Malar space height less than height of eye, 0.9 × basal width of mandible. Face width 1.3 × eye height and equal to height of face and clypeus combined. Clypeus with short flange along lower margin. Head slightly and roundly narrowed below eyes (front view). Antenna setiform, with 19 flagellomeres. First flagellar segment 2.8 × longer than its maximum width, 1.4 × as long as second segment; apical segment pointed apically, not sharp.

Mesosoma. Length 1.4 × its height. Subalar depression rugose with striation partly. Propodeum weakly curvedly sloping backward (lateral view).

Wing. Length of fore wing 3.6 × its maximum width. Pterostigma 3.3 × as long as wide, 0.8 × as long as R1 (metacarpus).

Legs. Hind femur 1.3 × as long as wide. Hind tarsus 0.7 × as long as hind tibia. Second tarsal segment 0.7 × as long as first segment, almost as long as fifth segment (without pretarsus).

Metasoma. Length of petiole 0.75 × its apical width, about equal to length of propodeum. Combined length of second and third tergites 0.6 × basal width of second tergite. Ovipositor sheath about the same length as metasoma, 4.0 × longer than petiole.

Sculpture and pubescence. Head mostly smooth, only face oblique subvertically strigate. Mesosoma and metasoma mostly smooth. Notauli wide and complete, deep and scrobiculate anteriorly, its remaining area shallow and smooth to slightly rugulose, not joining each other, obscuring in slightly rugulose area posteriorly. Mesopleuron, propodeum and a small portion of metapleuron with weak rugose-striate areas. All metasomal tergites entirely smooth and polished. Legs mostly smooth. Face and temple sparsely setose. Mesosoma, metasoma and legs sparsely pilose by short setae.

Colour. Body entirely honey yellow. Pterostigma brown. Veins honey yellow to brown. Ovipositor sheaths honey yellow, apical area black.

Male. Unknown.

Etymology. The name of this species (Latin fortis = strong and crura = leg) refers to its distinctly wide and thick femora and tibiae.
