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.
