Description
Summary:Casinaria compressiventris nov.sp. (figs 8, 20, 42) Holotypus: (♀) SP, Pipineos Contr. 23 km E Viella, Valencia d´Aneu 21.7.1990 Mart. Schwarz (coll. SCHWARZ). Paratypus: (♂) same location and date (coll. SCHWARZ). R e m a r k: This new species is closely related to C. cultellator AUBERT. It differs by transverse preapical flagellomeres, matte mesopleura with strong granulation and superficial punctures, and yellowish colour of the mandibles. D e s c r i p t i o n: ♀: Body length 7.5 mm. Flagella with 29 segments; 1 st flagellomeres length c.3.2x width; preapical flagellomeres wider than long. Head transverse, width 2.3x length. Temples narrow, strongly and roundly narrowed behind eyes. Distance of lateral ocelli to eyes 0.9x and between them 1.2x their diameter. Face strongly narrowed ventrally, finely rugose-punctate, minimal width 0.55x eye length and 0.9x width of frons. Malar space length 0.25x width of mandibular bases. Genal carinae not bent outwards ventrally, reaching hypostomal carinae in an acute angle. Hypostomal carina not elevated. Mesopleural discs granulate and superficially punctate, matte; specula granulate, matte; dorsal impressions with fine striae. Prepectal carina narrow, absent on transversal parts. Metapleura finely rugose; coxal carinae absent. Propodeum without distinct carinae, finely rugose-punctate; area petiolaris with moderately deep central impression, with fine transverse striation in apical third. Hind femora length 5.0x width, length of inner spurs of hind tibiae 0.7x hind metatarsi length. Areolets stalked, 2 nd recurrent veins distal to their middle; nervuli postfurcal; postnervuli intercepted in their middle; external angles of discoidal cell acute (75-80°); nervelli of hind wings slightly reclivous, not distinctly intercepted. Metasoma very slender; 2 nd tergite length 2.7x width; distance of thyridia from basal margins 1.5x their length; 3 rd tergite length c.2.3x width; following tergites strongly compressed laterally. Colour: Black. Palps yellow; mandibles except teeth and tegulae yellowish. Scapes reddish ventrally. Metasoma black, 2 nd to 7 th tergites with reddish suffusion laterally. Fore and middle coxae brownish; hind coxae and trochanters black; legs otherwise reddish; middle and hind trochantelli reddish-yellow; hind tibiae reddish, pale yellow basally, blackish subbasally and apically; hind tarsi except yellow base of metatarsi blackish. Pterostigmata dark brown. ♂: Body length 6.3 mm. Flagella with 30 segments, preapical flagellomeres about square. Impression of area petiolaris rather narrow and deep, transverse rugae stronger than in the ♀. 2 nd tergite length 2.0x width; 3 rd tergite length 1.7x width. Coxae black; hind femora narrowly infuscate apically. Structure and coloration otherwise as described for the ♀. H o s t s: unknown.
