First description of male (fig. 12, <i>a–e</i>; 13, <i>a–d</i>). M a t e r i a l e x a m i n e d. 1 Ơ, Uzbekistan, Kuldzhuktau, 9.05.1961 (ZMMU). Head somewhat wider than length, broadly rounded above eyes, occipital margin convex. Anterior clypeal margin slightly prominent medially. Eyes big, situated distinctly below midlength of sides of head, so that genae very short. Scape length about half of head width. Mandibles with five sharp teeth, apical one much longer than others. Sculpture of head dorsum quite coarse: frons and clypeus with longitudinal rugosity, surface between and behind lateral ocelli with transversal rugae, remaining part of head dorsum coarsely and densely punctated. Occipital margin and temples with not abundant, relatively short erect to suberect hairs. Mesosoma very long and low, scutum and scutellum very feebly convex, forming with propodeum more or less regular arch, notauli well developed. Petiole very long and low, twice longer than height, with almost straight anterior face and very widely rounded node dorsum. Petiole quite narrow, its node subcircle (seen from above), postpetiole&gt; 1.6 times wider than petiole. Scutum and scutellum finely and densely longitudinal ruguloso-striated, surface between rugulae finely, but densely punctated, lateral parts of dorsum of scutum smooth and shiny. Sides of mesosoma finely, but densely longitudinally striato-punctated. Petiolar node laterally with short longitudinal rugulae, its dorsum finely punctated, postpetole dorsally quite coarsely longitudinally rugose. Stipites of genitalia very smoothly curved inward apically (seen dorsally or ventrally), their apices convex, not excavated (seen from behind). Mesosoma and waist with sparse and quite short erect hairs. In contrast to known males of other species from <i>striativentre</i> -group, surface of first gastral tergite finely, but densely longitudinally striato-punctated (this sculpture is similar to that in workers and queens, but is much finer), remainder tergites with fine, but very obvious superficial microreticulation. Body colour dark reddish-brown, clypeus, mandibles and appendages brownish-yellow. Measurements of male (in mm): HL 0.61, HW 0.63, OL 0.26, GnL 0.04, SL 0.31, PL 0.443, PW 0.22, PH 0.22, PPL 0.24, PPW 0.36, PPH 0.32, HTL 0.83, ML 1.69, MH 0.94, SCL 1.20, SCW 0.94. Indices: CI 0.96, SI 1 0.51, SI 2 0.49, OI 1 0.42, OI 2 6.00, PI 1 2.00, PI 2 0.35, PPI 1 0.67, PPI 2 0.58, MI 1.81, SCI 1.28. T a x o n o m i c n o t e s. Emery (1898) described <i>T. schneideri</i> based on the single worker from Bukhara (Uzbekistan), collected by Prof. Oskar Schneider. As this species by the many diagnostic features (especially by the sculpture of the fist gastral tergite) is similar to <i>T. striativentre</i>, later on Emery had some objections to the taxonomic status of this species and requested Ruzsky to compare <i>T. schneideri</i> with the type specimens of <i>T. striativentre</i>. As a result, Ruzsky (1905 a: 766 <i>–</i> 767; 1905 b) confirmed heterospecificity of these taxa and proposed to consider <i>T. schneideri</i> as a subspecies of <i>T. striativentre</i>. The status of <i>T. schneideri</i> as a species was revived by Dlussky and Zabelin (1985). Karawajew (1912) described <i>T. striativentre</i> subsp. <i>schneideri</i> var. <i>longispina</i> from Turkmenistan (Repetek). Despite this name is unavailable (quadrinomen), we examined 2 “ syntype ” workers of this form with the labels: “Transkaspien, Repetek. Nr. 1741 W. Karawajew”, “ <i>Tetramorium striativentre</i> Em. <i>schneideri</i> Em. v. <i>longispina</i> Kar. Typus”, “ Syntypus <i>Tetramorium striativentre schneideri</i> v. <i>longispina</i> Kar. ” (SIZK). Here we may only confirm the opinion of Dlussky et al. (1990) that these specimens are <i>T. schneideri</i> with the very long propodeal spines. For the differences of <i>T. schneideri</i> and <i>T. striativentre</i> see Taxonomic notes to the latter species, above. <i>T. schneideri</i> well differs from two other species with the completely sculptured first gastral tergite (<i>T. saudicum</i> and <i>T. sabatinellii</i>) first of all by the subcircle petiolar node (it is distinctly transversal in the latter species), and by the finer longitudinal rugosity on the head dorsum (number of rugae between the frontal carinae level with the eyes&gt; 15, mean 23, same in the latter species &lt;15, means 12 … 13). D i s t r i b u t i o n. Central Asia, southern Kazakhstan, Afghanistan, Iran. E c o l o g y. In contrast to the previous species, distributed mainly on plains and foothills, it prefers desert and semi-desert biotopes and is one of the commonest ant species in many places. Nests build in a soil, sometimes under stones. Consumes mainly plant seeds, but also collects living and dead small invertebrates. Nuptial flight is in May — early June (for more details see Zakharov, 1976; Dlussky, 1981; Dlussky et al., 1990).
