3.2.4. Tribe † Valaaini trib. nov.

Type genus.

† Valaa Perrichot, 2009.

Median mesoscutal sulcus crenulate; parapsidal lines absent; axillae not connected at inner angles, separated by two triangular foveae; propodeum carinate. Protibia with stout apical spines; pro-, meso- and metatibiae shorter than combined length of tarsomeres. Fore wing hyaline, with C, Sc+R, A, Rs+M, cu-a, Rs, M and R1 tubular; pterostigma reduced; M not reaching apical margin; Rs apically strongly angled, arched towards stigma; costal, submarginal, marginal and radial+first cubital cells closed. Hind wing with Rs short, barely projecting beyond R1. Metasoma compact, shorter than mesosoma.

Comments.

The tribe † Valaaini trib. nov. is erected based on the results of the phylogenetic analyses, because † Valaa is not retrieved within a clade with other Dinapsini s.s., contrary to what was suggested by Perrichot (2009).
