R e m a r k: This species is closely related to Casinaria mesozosta (GRAVENHORST) and C. ischnogaster THOMSON, but differs by the black metasoma, darker hind femora, interstitial nervelli and straight and ventrally obsolete genal carinae.

D e s c r i p t i o n: ♀: Body length 5.5-8.0 mm. Flagella with 26-29 segments; 1 st flagellomere length 3.0x width; preapical flagellomeres slightly wider than long. Temples narrow, strongly narrowed behind eyes; head 2.2x wider than long. Ocelli large, distance of lateral ocelli to eyes 0.5-0.7x and between them 1.0x their diameter. Face moderately to strongly narrowed ventrally, finely rugose-punctate, minimal width 0.45- 0.6x eye length and 0.8-0.9x width of frons. Malar space length 0.2-0.4x width of mandibular bases. Genal carinae not bent outwards, obsolete ventrally, reaching hypostomal carinae far from mandibular bases in acute angle. Hypostomal carinae not elevated.

Mesopleural discs granulate and with superficial puncture; specula largely shining, almost smooth; dorsal impressions strongly striate; metapleura granulate. Prepectal carina narrow, absent on transversal parts. Metapleura finely rugose; coxal carinae not developed. Propodeum with short basal carinae (usually area basalis+basal half of area superomedia); area petiolaris slightly impressed medially, finely rugose or granulate. Hind femora length 4.4-4.8x width; length of inner spurs of hind tibiae 0.73x hind metatarsus length. Areolets stalked, 2 nd recurrent veins lateral of the middle; nervuli postfurcal; postnervuli intercepted below middle; external angles of discoidal cells acute (70-80°); nervelli of hind wing interstitial, not distinctly intercepted. 2 nd tergite length 1.7-1.8x width; distance of thyridiae from basal margins 1x their length; 3 rd tergite length 0.90-0.95x width.

Colour: Black. Palps, mandibles and tegulae reddish-yellow. Coxae black, sometimes fore and middle coxae ± reddish; fore and middle trochanters and trochantelli yellow; hind trochanters blackish; legs otherwise reddish; fore and middle femora ± darkened basally; hind femora red, often infuscate basally and/or apically, or completely brown to blackish; hind tibiae pale brown, ivory basally and externo-medially, brownish subbasally and apically; hind tarsi except ivory bases of metatarsi brownish-black. Pterostigmata brown.

♂: Flagella with 28-29 segments, preapical flagellomeres wider than long or almost square. Hind femora length 4.5x width. Metasoma rather stout; 2 nd tergite length 1.5-1.9x width; 3 rd tergite length 0.9-0.95x width. Fore and middle coxae sometimes ± reddish. Hind femora reddish or ± blackish. Fore and middle tibiae red, yellowish externally; hind tibiae red, yellow basally and externo-medially, black subbasally and apically.
