Casinaria parvula KRIECHBAUMER, 1894

Casinaria parvula KRIECHBAUMER, 1894: 253 ♀

Types lost (HORSTMANN 1995: 54). The short original description is not sufficient for an unequivocal diagnosis, therefore this taxon remains uninterpreted so far.

Face slightly narrowed ventrally, finely rugose-punctate, minimal width 0.68x eye length and 0.95 width of frons. Clypeus sometimes slightly protruding apically. Malar space length 0.4x width of mandibular bases. Genal carinae not bent outwards and obsolete ventrally, reaching hypostomal carinae near mandibular bases in an acute angle. Hypostomal carinae not elevated.

Mesopleural discs granulate and distinctly punctate, somewhat shining; specula granulate, matte; dorsal impressions with rows of granulae or fine striae. Prepectal carina not elevated and absent on the transversal parts. Metapleura finely rugose; coxal carinae not developed. Propodeum with basal carinae (area basalis+ basal part of area superomedia); area superomedia slightly longer than wide; area petiolaris slightly impressed, with fine irregular rugae. Hind femora length 4.5-5.4x width; length of inner spurs of hind tibiae 0.7x hind metatarsus length. Areolets stalked, 2 nd recurrent veins proximal or distal of the middle; nervuli postfurcal; postnervuli intercepted below its middle; external angle of discoidal cells 90°; nervelli of hind wing reclivous, intercepted in apical 0.4-0.6. 2 nd tergite length 1.2-1.5x width; thyridia roundish, distance to basal margins 0.5-1.0x their length; 3 rd tergite length 0.65-0.85x width.

Colour: Black. Palps yellow-red to brownish. Mandibles except reddish teeth and tegulae brown to blackish. Postpetiolus usually red apically, 2 nd tergite red in the apical 0.5-0.7, 3 rd tergite completely red, 4 th tergite completely red or with black apical margin, sometimes 5 th tergite red basally. All coxae and trochanters black; trochantelli reddish; legs otherwise red, (middle) and hind femora narrowly infuscate at apex; hind tibiae ± infuscate basally and/or apically; hind tarsi except narrow yellow basal spots of metatarsi brown to black. Pterostigmata brown.

♂: Flagella with 33-35 segments, all flagellomeres longer than wide. Temples moderately narrowed behind eyes. Hind femora length 4.6-5.3x width. 2 nd tergite length 1.05-1.3x width, 3 rd tergite length 0.6-0.8x width. Hind femora completely red or infuscate apically.
