Athacryvac alternatus Braet and van Achteberg 2011: 285
Diagnosis. Antenna brown with apical segments white; body entirely honey yellow, frequently with metasomal terga 1–3 brown basally and pale yellow apically, and mesoscutum and base of propodeum brown; occipital carina complete and evenly rounded dorsally, ventrally not reaching hypostomal carina; scutelar sulcus with one pair of longitudunal carina, withou median carina; fore wing vein r-m absent; fore wing vein 1-CU1 about 2 times longer than vein cu-a; hind wing vein RS virtually straight; frequently with at least first and second flagellomeres fused; antenna long, 2.5 times longer than fore wing; hind coxa transverselly costate dorsally.
Additional characters. First two or three flagellomeres partially to completely fused; POL:OD:OOL = 4:3:6 (ocell-ocular distance about 2.0 times as long as diameter of lateral ocellus); malar space 1.8–2.2 times longer than basal width of mandibles and about 0.4 times eye height in frontal view; pronotal collar granular-coriaceous with a pair of virtually transverse carina; scutelar sulcus with 1–3 longitudinal carinae; ventral midline of mesopleuron set within more or less deep and crenulate sulcus; fore wing veins 1-CU1:2-CU1:cu-a = 10:23:5 (vein 1-CU1 about 0.4 times as long as vein 2-CU1 and 2.0 times vein cu-a); petiole long and basally narrowing, about 2 times wider apically than basally, length of first tergum 1.53–1.76 times its apical width, base of petiole without lamelliform lateral flanges; apex of ovipositor sheaths with thin and pointed projection.

Discussion. In the original description and key, the first tergum is described as 1.9 times longer than apical width. For all the specimens available for comparison, and measurements made based on drawing of the holotype, these proportions varies from 1.55–1.78, the holotype’s petiole 1.76 times longer than apical width. The first two or three flagellomeres are fused in variable degrees, but never completely separated, in the Brazilian specimens. The spaces within the rugose-costate sculpturing of second metasomal terga are filled with finely reticulate sculpturing in all specimens observed. The eye length is 3.2–3.8 times longer than temples in dorsal view (including the holotype). Aleiodes alternatus is similar to A. achterbergi sp. nov., A fuscatus and A. paradoxus sp. nov. by having a dorsally complete and evenly rounded occipital carina, ventrally not meeting hypostomal carina, the fusion of first and second flagellomeres, fore wing vein 1-CU1 long, at least 2.0 times longer than cu-a, hind wing vein RS virtually straight, and ventral midline of mesopleuron set in a crenulate sulcus. These four species agree entirely with the original description of Athacryvac. Aleiodes alternatus is the only species lacking the fore wing vein r-m.
Distribution. Brazil, Colombia, French Guiana and Peru.
