Description of Rhinusa exigua sp.n. from Turkey (Coleoptera: Curculionidae: Curculioninae)

R. CALDARA & B.A. KOROTYAEV

Abstract Rhinusa exigua sp.n. (Coleoptera: Curculionidae: Curculioninae) from Turkey is described and figured. The differences from the very closely related R. antirrhini (PAYKULL, 1800) are reported.

Key words: Coleoptera, Curculionidae, Curculioninae, , Rhinusa exigua sp.n., Turkey.

Introduction

A very small of Rhinusa STEPHENS, 1829 related to R. antirrhini (PAYKULL, 1800) has been collected in Turkey, where it was found only on a single species of Linaria with very small pale blue flowers. After examination of the species belonging to the R. antirrhini group sensu REITTER (1908), FREMUTH (1972) and BEHNE (1988), we describe it as new to science. Acronyms CAL Coll.

middle to apex, with scrobe clearly visible, moderately striate-punctate in basal 0.5, smoother and shining in apical 0.5, in medial 0.3 with wide median sulcus, from base to middle covered with subrecumbent to suberect, moderately dense scales. Frons slightly wider than base of rostrum, without fovea. Eyes weakly convex. Antennae dark brown, inserted at middle of rostrum; scape three times as long as wide; funicle distinctly longer than scape, with first segment 1.5 times as long as wide, distinctly more robust than and 1.5 times as long as second segment, which is two times as long as wide, third-fifth segments becoming gradually more transverse; club short, oval, uniformly pubescent.

Legs moderately robust, with scales sparse and distinctly shorter than width of tibia; all femora with minute tooth; tibiae with moderately robust unci; tarsi with first segment two times as long as wide, second segment 1.5 times as long as wide, third segment bilobed and distinctly wider than second; claws connate in basal 0.5. Abdomen with dense and moderately regular punctures, with recumbent to subrecumbent, mode- rately dense scales; length ratio of ventrites 1+2/3+4: 2.12. Median lobe of aedeagus long, in dorsal view with parallel sides as in Fig. 6. Female: As male except rostrum slightly longer (rostrum length/pronotum length 0.82), in lateral and dorsal view (Figs. 4–5) narrower and finer in apical 0.5. Uncus of metatibia very small. Spermatheca as in Fig. 7. VARIABILITY: Length 1.3–1.6 mm (rostrum excluded). In some specimens pronotum and elytra are widest at middle, whereas the scales on the elytral interstriae may be partly arranged in two irregular rows. Fig. 1: Rhinusa exigua, holotype, habitus.

vestiture whitish brown with sericeous reflections and suberect to erect; median lobe of aedeagus with sides narrowed at middle. The rostrum and the aedeagus of R. antirrhini were well illustrated by FREMUTH (1972) and Bemerkenswerte Käferfunde aus Österreich (XVII) BEHNE (1988). It is noteworthy that the aedeagus of R. exigua is similar to that of R. florum (Coleoptera) (RÜBSAAMEN, 1895) (= R. smreczynskii (FREMUTH, 1972)), which however differs clearly from the new species in the shape of the rostrum, which in lateral view is regularly and not abruptly narrowed at the antennal insertion. There are no differences in the shape of the female genitalia R. SCHUH & I.S. PLONSKI between these three species. Finally R. exigua revealed extensive genetic differentiation from R. antirrhini and R. florum in a sequence of 696 base pairs of the mitochondrial cytochrome oxidase II (COII) gene (Toševski, Abstract unpublished data).
