Zootaxa 2020 2020-11-30 4888 1 1 84 Baker & Heraty 2020 [151,397,1878,1904] Insecta Eucharitidae Orasema Animalia Hymenoptera 49 50 Arthropoda species acuminata  ( Figs 26–28)   Diagnosis.Recognized by the following combination of characters: antenna with 7 funiculars ( Figs 27D, E, 28D), mesoscutum and mesoscutellum coarsely rugose-areolate and mesoscutum in dorsal view with curvature of lateral lobe discontinuous with curvature of midlobe ( Figs 27F, 28G), eyes bare ( Figs 27B, 28B), antecostal sulcus smooth ( Fig. 28E).   Description. Female.Length 2.6–3.7 mm. Color.Scape yellow; anellus pale brown; flagellum dark brown. Mandible pale brown with dark edges; maxilla and labium pale brown. Coxae brown with iridescence; tibiae yellow. Fore wing hyaline; venation pale brown. Petiole same as mesosoma; gaster dark brown with iridescence. Head.Head in frontal view subtriangular; scrobal depression shallow, laterally rounded, with transverse striae; longitudinal groove between eye and torulus absent; eyes bare; clypeus smooth; epistomal sulcus vaguely defined; anterior tentorial pits deeply impressed. Labrum with 4 digits. Mandibular formula 3:2; palpal formula 3:2. Occiput imbricate, emarginate in dorsal view, dorsal margin rounded; temples present. Scape not reaching median ocellus. Pedicle small and globose. Flagellum with 7 funiculars; anellus disc-shaped. Mesosoma.Mesoscutal midlobe rugose-areolate, moderately setose; lateral lobe rugose-areolate, curvature of lateral lobes discontinuous with curvature of midlobe in dorsal view; notauli deep. Axilla rugose-areolate; scutoscutellar sulcus broad, regularly foveate; mesoscutellar disc as long as broad, rugose-areolate; frenum and axillula rugose-areolate. Propodeal disc flat, without depression or carina, areolate; callus areolate, with several long setae. Propleuron convex, imbricate. Prepectus triangular dorsally, strongly narrowed ventrally, rugose-areolate. Mesepisternum areolate, broadly rounded anterior to mid coxa; postpectal carina weak. Transepimeral sulcus distinct. Hind femur densely setose laterally. Fore wing with marginal fringe relatively long; marginal vein setose; stigmal vein slightly longer than broad; postmarginal vein several times longer than stigmal vein. Hind wing costal cell setose. Metasoma.Petiole cylindrical, linear in profile, rugose, ventral sulcus absent. Antecostal sulcus smooth; acrosternite posteriorly rounded ( Fig. 28E).  Male.Length 2.6–3.2 mm. (Known only for  O. acuminata).  Phylogenetics.Only one species,  O. acuminata, has been sampled for molecular data, and was referred to as “ Orasema_nsp_nr_brasiliensis_PER_AE_D4889” by Baker et al. (2020). This species was the sister to the majority of the  Orasema xanthopusgroup in most analyses ( Baker et al. 2020).   Key to species of the  Orasema acuminataspecies group     1)Clava strongly pointed ( Fig. 27D, E); sculpture on face more rugose than reticulate ( Fig. 27B); upper mesepimeron areolate ( Fig. 27C); femora mostly light brown ( Fig. 27A); body color green-blue-purple ( Ecuadorand Peru)...................................................................................................  Orasema acuminata  n. sp.   -Clava subovate ( Fig. 28D); sculpture on face more reticulate than rugose ( Fig. 28B); upper mesepimeron smooth ( Fig. 28C); femora dark brown ( Fig. 28A); body color dark blue ( Honduras)..............................  Orasema cerulea  n. sp.
