Genus Lysodinotrema Fischer, 1995

Lysodinotrema Fischer, 1995: 717; Fischer 2002: 103; Yu et al. 2016.

Type species.

Lysodinotrema madli Fischer, 1995, by original designation (Figs 24, 25).

Material examined.

Holotype ( Lysodinotrema madli) Madagascar: • ♀, Ste. Marie Flues Manandriana, 14–25. xi. 1994 (Fischer leg.) (NHMW).

Diagnosis.

Mandible small, simple, tridentate. Paraclypeal fovea short, remaining far from the inner margin of eyes. Mesoscutum without mesoscutal pit; notauli present only in anterior half of mesoscutum; precoxal sulcus present; propodeum mainly sculptured, without areola. In fore wing, marginal cell never shortened; vein r originating from basal quarter of pterostigma; vein 2 - SR present and sclerotised; veins m-cu and cu-a always postfurcal; first subdiscal cell completely open posteriorly and without vein 2-1 A. Hind wing without closed cells. Metasoma of ♀ more or less distinctly compressed. Ovipositor sheath shorter than metasoma.

Remarks.

This rare genus, with only three described species from the tropical areas ( L. madli Fischer, 1995, L. minimum Fischer, 2004, L. sarawakense Fischer, 1995), is considered to be related with Dinostigma Fischer, 1966, because of sharing the open first subdiscal cell in the fore wing. However, the combination of closed cells in the hind wing (absent in Dinostigma), presence of vein 2 - SR of fore wing (absent in Dinostigma) and of the precoxal sulcus (absent in Dinostigma) makes it possible to maintain Lysodinotrema as a valid genus.
