Review of subtribe Singilina Jeannel, 1949, of the Middle East and Central Asia (Coleoptera, Carabidae, Lebiini) Author Anichtchenko, Alexander text ZooKeys 2011 155 1 50 http://dx.doi.org/10.3897/zookeys.155.1779 journal article http://dx.doi.org/10.3897/zookeys.155.1779 1313-2970-155-1 Singilis kryzhanovskii sp. n. Material examined. Holotype: ♂, Iran, Khorasan prov., Gonobad area, 10 km SW Khezri, 1800m, 22.V.2009 Kolesnichenko K. leg.; Paratype: ♂, Kopetdag, 12 km SW Kizyl-Arvat, light trap, 5.VII.1953 Kryzhanovskii leg. (ZIN). Diagnosis. This new species shares with Singilis klimenkoi and Singilis saeedi the overall appearance and uniformly brownish yellow body coloration. It differs from Singilis klimenkoi by its larger size and by the short and thin setae on elytral intervals. From Singilis saeedi it is differentiated by the presence of weak setiferous pores along only odd elytral intervals, i.e. all elytral intervals of Singilis saeedi with pores along striae. The aedeagus also differs dramatically. Description. Length 6.3-6.5 mm. Uniformly yellowish red-brown (Fig. 20). Head very coarsely and deeply irregularly punctate, with distinct isodiametric microsculpture, punctures confluent near eyes, separated by over three diameters on the frons. Clypeus smooth, with a few small punctures near base. Eyes very large and bulging. Second supraocular seta just before the level of the posterior margin of the eye. Temples very short, smooth. Scape smooth, with one very long and 3-4 short subapical setae; pedicel with the usual band of apical setae; antennomere III with two bands of apical setae. Antennae pubescent from the basal third of antennomere IV. Pronotum 1.16 times as wide as head, 1.36-1.42 times as wide as long, widest just behind marginal setae. Anterior margin straight, anterior angles effaced, sides broadly and evenly rounded, slightly sinuate towards posterior angles, which are rectangular and protrude as minute denticle. Punctation irregular, punctures (especially on disc) shallower and sparser than on head, confluent at basal grooves. Lateral explanate margin even from apex to marginal setae, then rapidly widened and flat. Posterior pore right in front of angle. Basal grooves shallow. Pronotal base extended in a rounded median lobe. Furrow deep. Microsculpture as on head. Elytra subparallel, 1.4 times as long as wide. Intervals 1, 3, 5 and 7 with small pores bearing minute inconspicuous setae. Microsculpture as on pronotum. Apical edge straight, rounded at suture. Striae deep, slightly punctate. Intervals 4-8 convex in basal half, gradually flattened towards apex; other intervals slightly convex at base and flat at apex. Legs pale brownish yellow. Tarsomere V with 5 pairs of ventral setae. Claws with 5 teeth. Episterna all smooth. Abdominal sterna with long pubescence. Aedeagus - Fig. 45. Aedeagal median lobe moderately broad, ventral surface straight at midlength, apical fourth of lobe slightly downturned. Apex of median lobe long and expanded slightly near rounded tip. Internal sac with numerous long and large spines. Variation. In the holotype, elytral intervals are more convex and striae more crenulate than in the paratype, whose striae are almost smooth. However the aedeagal configuration is identical, and so the two specimens are considered conspecific. Name derivation. Named after the eminent Russian coleopterist Oleg Kryzhanovsky. Distribution. Iran, Turkmenistan.
