Tribe Palaeocharmontini nov.

Type genus: Palaeocharmon gen. nov., see below.

Description.—Occipital carina possibly complete, but very fine medio−dorsally. Eyes very large; malar space very narrow, almost non−existent. Ocelli enlarged ( Figs. 1A, B , 2A). Maxillary palpi 6−segmented; labial palpi 4−segmented, with third segment very small and suboval. Scape weakly thickened (Fig. 2B). Apical segment of antenna with long and slender apical spine (Fig. 2D). Scuto−scutellar suture indistinct. Scutellum posteriorly without furrow ( Fig. 1C ). Sternaulus very shallow ( Figs. 1B , 2B, C). Prepectal and postpectal carinae absent ( Figs. 1B , 2B, C, E). Propodeum possibly without propodeal bridge between metasomal and coxal cavities. Tibial spurs and claws short and simple (Fig. 2D). Discoidal (discal) cell of fore wing anteriorly distinctly petiolate (Fig. 2G). Nervulus (cu−a) weakly antefurcal (Fig. 2G). First transverse anal vein (2A) present but fine and spectral; second transverse anal vein (a) absent. Brachial (subdiscal) cell closed apico−posteriorly by brachial (CU1b) vein (Fig. 2G). In hind wing, first transverse anal (2A) and recurrent (m−cu) veins present (Fig. 2F); anal (plical) lobe not separated and rather narrow. Metasoma without carapace ( Fig. 1B, C ). First tergite with distinct laterope and distinct dorsal carinae (Fig. 2B, C).
