Casinaria cultellator AUBERT, 1959: 159 ♀♂

Lectotypus: (♀) 21.8.1953 Cap d´Ail (A.M.) (Lausanne), studied and herewith designated.

Paralectotypus: (♂) 31.7.1957, Castellar/Menton (A.M.) (Lausanne), studied and herewith designated.

D e s c r i p t i o n: ♀: Body length 8-10 mm. Flagella with 33 segments; 1 st flagellomeres length c.2.3x width; preapical flagellomeres slightly longer than wide. Temples narrow, roundly narrowed behind eyes, length 0.7x eye width; head 2.2x wider than long. Ocelli large, distance of lateral ocelli to eyes 0.7-0.8x and between them 1.6x their diameter. Face slightly narrowed ventrally, coarsely rugose-punctate, minimal width 0.55x eye length and 0.95 minimal width of frons. Malar space length 0.2x width of mandibular bases. Genal carinae strongly bent outwards ventrally, reaching mandibular bases in an angle of 90°. Hypostomal carinae not elevated.

Mesopleural discs finely granulate and distinctly punctate, more or less shining; specula striate; dorsal impressions wide and deep, strongly striate. Prepectal carina not elevated. Propodeum without distinct carinae, coarsely rugose; area petiolaris with rather deep and narrow impression, the impression with coarse transverse rugae. Hind femora rather stout, length 4.2x width; length of inner hind tibial spur 0.7x length of hind metatarsus. Areolets stalked, 2 nd recurrent veins lateral of their middle; nervuli postfurcal; postnervuli intercepted in the middle; external angles of discoidal cells acute (70-80°); nervelli of hind wing slightly reclivous, not distinctly intercepted. Metasoma very slender, apical tergites strongly compressed. 2 nd tergite length 2.3x width; distance of thyridia from basal margin 2x their length; 3 rd tergite length 1.7x width.

Colour: Black. Palps and mandibles except teeth brown; scapes reddish internally. Tegulae cream-yellow. 2 nd tergite with diffuse reddish-brown band subapically. All coxae and trochanters black; legs otherwise red; fore femora apically and fore tibiae externally yellow; middle tibiae yellow externally, slightly darkened apically; middle tarsi brownish; hind tibiae reddish, ivory basally, brown subbasally and apically; hind tarsi except basal ivory ring of hind metatarsi blackish. Pterostigmata brown.

♂: Body length 9 mm. Flagella with 34 segments, all flagellomeres longer than wide. Mesopleural discs granulate and strongly punctate; specula partly striate, partly smooth and shining. Hind femora length 4.7x height. Metasoma strongly compressed; 2 nd tergite length 2.4x width; 3 rd tergite length 1.8x width; thyridia roundish, distance from basal margin 1x their length. Metasoma black; hind tibiae yellowish externo-medially; fore tarsi infuscate apically. Structure and coloration otherwise as in ♀.
