Pterostichus (Morphohaptoderus) primitivus Fedorenko, sp.n.

Fig. 3 .

MATERIAL. Holotype ♀ ( ZMMU) with the label same as for the holotype of P. glabellus sp.n.

DIAGNOSIS. No significant differences from P. glabellus sp.n. other than the elytra with parascutellar seta and three discal setae, d 1 in stria 3, d2 and d 3 in stria 2; fe 3 not sexually dimorphic.

DESCRIPTION. Body as in Fig. 3 , BL 9 mm. Labrum without median impression. Pronotum broadest two fifths from apex, with base nearly straight and a third wider than apex. Elytra with humeral toothed a bit larger. Striae subpunctate, stria 7 inside humeral angle; parascutellar striole entire, stria 1 adjoining parascutellar seta. D1/EL 0.25, D2/ EL 0.55, D3/EL 0.77. USS: 13–15. Propleura impunctate.

Gonopode IX slightly larger, gonocoxite more elongated toward apex, with ensiform setae inserted close to base.

DISTRIBUTION. Known from the type locality only.

NAME. Refers to the complete setation of the elytra, which seems to be primary, plesiomorphic, primitive for at least the three species described here.

HABITATS AND HABITS. Holotype was hand collected in a habitat similar to that of P. glabellus sp.n.
