Anteris atriceps Kieffer, 1913a: 428 . Original description, preoccupied by Paratrimorus atriceps Kieffer (1910) ; Kelner-Pillault, 1958: 149 (type information); Masner, 1976: 41 (description, taxonomic position).

Psilanteris atriceps: Kieffer, 1916: 177 (generic transfer); Kieffer, 1926: 433, 434 (description, keyed).

General (Figs. 35, 36): Female body length: 1.5–2.6 mm (n=14). Male body length: 1.5 mm (n=1). Head: Color of female head: black. Mandible color: mostly yellow to amber or orange yellow. Body color of male: yellow laterally and ventrally, darkening to light brown to brown dorsally. Lateral ocellus position: touching compound eye. Pilosity of medial frons between anterior ocellus and apex of torular triangle: present. Sculpture of medial glabrous area of frons: inapplicable, glabrous patch absent (Fig. 39). Mesosoma (Figs. 37, 38): Color of female mesosoma: yellow to amber or orange yellow. Dorsal surface of lateral pronotal area adjacent to mesoscutal suprahumeral sulcus: with uniform microsculpture only, or with conspicuous crenulations or scrobes. Setae on netrion: absent. Notaulus: indicated by a row of pits. Metascutellum: projecting, particularly medially where it comes to a truncated point or projecting, truncated throughout, roughly rectangular. Mesopleural depression sculpture: upper half more or less nitid, lower rugulose (smaller individuals) to irregularly foveate (larger individuals). Pilosity bounding anterior margin of posterior mesepimeral area: completely absent, or partially present dorsally. Legs: Coxae color: yellow (as in remainder of leg). Color of legs beyond coxae: uniformly yellow, without infuscations. Wings: Length of fore wing: not http://atbi.biosci.ohio-state.edu/HymOnline/map-large.html?id=223470 http://www.morphbank.net/?id=226858

or just reaching posterior margin of metasoma or surpassing posterior margin of metasoma. Hind wing submarginal vein: tubular from wing base to hamuli. Metasoma: Color of female metasoma: yellow to amber or orange yellow. Longitudinal sculpture of T1: carinate, parallel to subparallel, interspersed with fine rugulose sculpture. Female T1 horn: absent, sculpture more or less uniform throughout T1. Anterior strip of T2: nitid. Female T6 width to length ratio: wider than long (striplike). Female T6 carinate basal extension of

T6 posterolateral margin: without short spine or carinate expansion absent or apparently so (Fig. 40). S6 shape at tip: broadly rounded to very slightly angular, without obvious lobe.

Diagnosis. Differs from other species in which the hind wing submarginal vein is present by the bluntly pointed metascutellum (Fig. 19).

Comments. Axea atriceps has a relatively broad distribution throughout Southeast Asia. Though there is noticeable size variation we were unable to discern corroborating characters which might suggest the existence of more than one species. The species is remarkably similar to the new species described here from India, A. yama . If variation in the form of the metascutellum is ultimately observed then the distinction between A. atriceps and A. yama should be revisited.
