Figs 1F , 2E , 3F , 4F , 7B Diagnosis Body 4.3 mm long. LFW 2.5 mm . Wings bi-banded; head and mesosoma dark castaneous nearly black; metasoma dark castaneous. Head longer than wide. Malar space shorter than VOL, convergent anteriorly. Eye very small. Frons foveolate. Ocelli large. Mesosoma with pronotal disc as long as wide, foveolate, with side slightly concave, posterior margin concave; longitudinal pronotal sulcus hardly distinct, incomplete. Metapectal-propodeal complex shorter than metapectal-propodeal complex halfwidth, with longitudinal ridge between metaposnotal median carina and metaposnotal-propodeal suture; metaposnotal surface areolate; posterior spine of metapectal-propodeal complex present, short, thick, parallel. Propodeal declivity areolate. Lateral surface of metapectal-propodeal complex areolate. Metasoma with hypopygium longer than wide; anterior stalk slender and short; posterior margin with branches short and wide. Genitalia with paramere apex glabrous; aedeagus slender, with apex aligned with paramere apex, apical margin rounded, lateral margin of basal portion slightly convex. Material examined Holotype VIETNAM • ♂ ; Djiring; alt. 1200 m ; 22–28 Apr. [19]60; Grasse, L.W . Quate leg.; BPBM . Remarks This species was originally described in Sulcomesitius and recorded from Vietnam ( Móczár 1977 ). We examined the holotype male deposited at BPBM, and the analyses reveal that it fits the concept of Astromesitius gen. nov. , mainly because of the hypopygium shape. Thus, we propose a new combination for this species from Sulcomesitius to Astromesitius gen. nov.
