Genus Sifraneurus gen. n.

Type species: Sifraneurus strigifer sp. n.

Diagnosis

Flagellum with two funicular and three claval segments (figure 138); malar sulcus strong, wide just below eyes and narrows off towards mouth opening (figures 137, 138); mid lobe of mesoscutum with numerous scattered setae, side lobes with a marginal carina at ‘shoulders’ which separates upper and lower surfaces of mesoscutum; scutellum 0.9× as long as wide, with two pairs of setae; prepectus triangular, smooth and shiny; dorsellum visible in dorsal view; propodeal callus with many (25) setae; fore wing (figure 10) speculum ± covered with setae; postmarginal vein absent; submarginal vein with three setae on dorsal surface; costal cell with a complete row of setae on ventral surface; first gastral tergite with strong striations anteromedially (figure 10).

Monophyly and relationships

Sifraneurus belongs in the Entedononecremnus genus group, indicated through: frontal, vertexal and occipital sutures absent; eyes bare; posterolateral propodeum extended in a point. The generic status of Sifraneurus is justified through a set of apomorphies not present in any other genus of this genus group: malar sulcus strong, wide just below eyes and narrows off towards mouth opening; with a carina on side lobe of mesoscutum which separates upper surface from lower surface (also present in Xenopomphale in the Euderomphale genus group); postmarginal vein absent; fore wing speculum ± covered with setae; first gastral tergite with strong striations anteromedially, otherwise smooth and shiny.

Description

Flagellum with one small discoid anellus, two funicular segments, F1 distinctly smaller (narrower and shorter) than F2, and three claval segments. Mandibles with two large teeth. Clypeus delimited by a groove. Eyes bare. Frontal, vertexal and occipital sutures absent. Frons and vertex with weak reticulation, shiny.

Pronotum reduced and strongly narrowed medially, not visible in dorsal view. Prepectus triangular, smooth and shiny, completely delimited from mesopleuron. Thoracic dorsum with strong and engraved reticulation. Side lobes of mesoscutum with a blunt carina at ‘shoulders’ which separates upper surface from lower surface; mid lobe with numerous scattered setae; notauli absent. Axillae partly advanced in front of scuto-scutellar sulcus, separated from mesoscutum by a distinct groove. Scutellum with two pairs of setae; 0.9× as long as wide. Transepimeral sulcus curved. Propodeum with posterolateral part drawn out in a point; spiracular sulcus absent; propodeal callus with 25 setae; with a complete median carina, carina becoming wider and reticulate with small meshes posteriorly, also with a carina from apex of median carina to spiracle; surface above lateral carina smooth and shiny, below carina reticulate with small meshes. Fore wing with three setae on dorsal surface of submarginal vein; submarginal vein smoothly joining marginal vein; costal cell with a complete row of setae on ventral surface; speculum ± absent; postmarginal vein absent.

Petiole not visible, presumably small. First gastral tergite with strong striations anteromedially, otherwise smooth and shiny, without basal carina; remaining tergites smooth and shiny. Female hypopygium 0.9× as long as length of gaster.
