Genus Guyotemaimetsha Perrichot, Nel & Neraudeau, 2004a

Guyotemaimetsha Perrichot, Nel & Néraudeau, 2004a: 159 [ Incertae sedis in Ceraphronoidea sensu Rasnitsyn 2002]. Type species: Guyotemaimetsha enigmatica Perrichot, Nel & Néraudeau, 2004a. Rasnitsyn and Brothers 2009: 192 [in Maimetshidae ]; Ortega-Blanco et al. 2010: 266; Vilhelmsen et al. 2010a: 661.

Revised diagnosis.

Male: total body length (excluding mandibles and parameres) 1.7 to 2.9 mm; compound eyes oval and bulging, large, 0.66 × height of head; vertex without longitudinal medial line; fine occipital carina present; mandibles asymmetrical, right with four teeth and left with three teeth; scape flattened laterally, short, its maximal width 0.9 × its length; pedicel nearly as broad as long, 0.75 × length of scape; 14 flagellar articles cylindrical in shape and progressively shortening and slightly narrowing; maxillary palpus apparently with five palpomeres; labial palpus apparently with three palpomeres, all short; forewing with pterostigma moderately long, shorter than [2R1]; r-rs originating within apical one-third of pterostigmal length; 2R present as long stub, about half length of 1R; [1M] small, nearly rhombic, with first abscissa of Rs+M one-half length of second abscissa (2Rs+M), so that apical corner (junction of Rs+M and 1m-cu crossvein) positioned anterior to pterostigma; [1Rs] triangular, with Rs and 1rs-m crossvein both fade to become nebulous posteriorly; cross-veins 2rs-m and 2m-cu at most spectral, generally absent; hind wing with cells [R] and [Cu] enclosed by nebulous veins, with free apex of Cu.

Female: very similar to male but larger, total body length (excluding mandibles and ovipositor) 3.7 to 4.1 mm; pedicel more elongate, 0.75 × as broad as long, 0.85 × length of scape; legs with tarsal plantulae; ovipositor apparently simple, not serrate or toothed.

Comments.

Guyotemaimetsha is most similar to Maimetsha in the absence of cell [2Rs]. It differs in cell [1Rs] being anteriorly petiolate instead of sessile, the hind wing with a free apex of Cu, the absence of a medial line on the vertex, and the presence of tarsal plantulae in females.
