Casinaria morionella HOLMGREN, 1860: 48 ♀♂

Types lost, interpretation according to original description and former authors.

D e s c r i p t i o n: ♀: Body length 6 mm. Flagella stout, with 23-26 segments; 1 st flagellomeres length 3.0x width; preapical flagellomeres slightly wider than long. Temples narrow, strongly but roundly narrowed behind eyes; head 2.2-2.4x wider than long. Distance of lateral ocelli to eyes 0.9x and between them 1.6x their diameter. Face slightly narrowed ventrally, finely granulate, minimal width 0.67x eye length. Malar space length 0.3-0.5x width of mandibular bases. Genal carinae not bent outwards, obsolete ventrally, reaching hypostomal carinae far from mandibular bases in an acute angle of 70°. Hypostomal carinae not elevated.

Mesopleural discs finely granulate, not distinctly punctate (rarely with superficial punctures); specula granulate; dorsal impressions slightly developed, only with fine rows of granulae. Prepectal carina not elevated and absent on the transversal parts. Metapleura finely granulate; coxal carinae absent or sometimes partly present. Propodeum with complete strong carinae; area superomedia about as long as wide; area petiolaris slightly but very widely impressed, with irregular transversal rugae. Hind femora stout, length 3.9-4.0x width; length of inner spurs of hind tibiae 0.8x hind metatarsus length. Areolets stalked, 2 nd recurrent veins distal of the middle; nervuli distinctly postfurcal; postnervuli intercepted below middle; external angles of discoidal cells acute (70-75°); nervelli of hind wing not or weakly intercepted in apical 0.8. 2 nd tergite length 1.1-1.2x width; thyridia transversely oval or roundish, distance to basal margins 0.5-1x their diameter; 3 rd tergite length 0.75-0.85x width.

Colour: Black. Palps, mandibles except teeth, tegulae and fore and middle trochantelli yellowish. Scapes and pedicels partly reddish. Metasoma black. Fore and middle coxae brownish to blackish, sometimes reddish frontally; legs otherwise red; hind femora sometimes darkened basally; hind tibiae red, usually yellowish-red (rarely reddishbrown) basally, pale brownish subbasally and in apical 0.2; hind tarsi dark brown, hind metatarsi narrowly yellow at base. Pterostigmata brown.

♂: Flagella with 26 segments, preapical flagellomeres slightly longer than wide. Sometimes fore and middle coxae ± reddish. Sometimes scapes and pedicels reddishyellow ventrally. Structure and colour otherwise as described for the ♀.
