Pella reuteri, Assing, 2008

Assing, V., 2008, Three new species of Pella STEPHENS from Turkey and Iraq, with a checklist of the species recorded from Turkey (Coleoptera: Staphylinidae: Aleocharinae: Lomechusini), Linzer biologische Beiträge 40 (1), pp. 235-243 : 241-242

Pella reuteri nov.sp. ( Figs 14-17 , 20-21 )

T y p e m a t e r i a l: Holotype ♀: "N-Irak, N Mosul - SW Hakkari, Al-Amadiya, 28.IV.2007, 1200 m, leg. C. Reuter / Holotypus ♀ Pella reuteri sp. n. det. V. Assing 2007 " (cAss). Paratype ♀: same data as holotype (cFel).

D e s c r i p t i o n: Measurements (in mm) and ratios (holotype, paratype): AL: 1.92, 1.87; HL: 0.68, 0.69; HW: 0.92, 0.94; PW: 1.21, 1.27; PL: 0.85, 0.88; EL: 0.85, 0.88; EW: 1.53, 1.57; AW: 1.45, 1.48; TiL: 0.89, 0.91; TaL: 0.68, 0.71; TL: 6.1, 6.3; HW/HL: 1.36, 1.35; PW/HW: 1.31, 1.35; PW/PL: 1.42, 1.45; EL/PL: 0.99, 1.00; EW/PW: 1.26, 1.24; AW/EW: 0.95, 0.94; TiL/TaL: 1.31, 1.28.

Externally (coloration, size, shape) as in P. ruficollis (GRIMM 1845) - see illustrations of habitus and forebody ( Figs 14-16, 18 ) for comparison -, but distinguished as follows:

Elytra with dense, fine, but distinct puncturation ( Fig. 15 ). Abdomen with less pronounced microsculpture, distinctly less dense and more distinct puncturation, and more glossy ( Fig. 16 ; for an illustration of the abdomen of P. ruficollis see Fig. 19 ); puncturation of tergite VI very sparse (in P. ruficollis dense and fine).

6: unknown.

♀: posterior margin of tergite VIII ( Fig. 21 ) distinctly concave in the middle (in P. ruficollis only indistinctly concave at most ( Fig. 24 )); spermatheca larger ( Fig. 20 ), duct proximally more abruptly curved and subproximally straighter (see Figs 22-23 for spermatheca of P. ruficollis).

C o m p a r a t i v e n o t e s: The species is doubtlessly the adelphotaxon of P. ruficollis, the sole representative of the P. ruficollis group ( MARUYAMA 2006). For characters separating the two species see the description above.

E t y m o l o g y: The species is dedicated to Christoph Reuter, who discovered the types, in appreciation of his courage in collecting insects in such a perilous region.

D i s t r i b u t i o n a n d b i o n o m i c s: The types were collected in northern Iraq, in the area north of Mosul, at an altitude of 1200 m in April. Additional bionomic data are unknown.
