Abstract
In a survey carried out on mesostigmatid mites associated with Coleoptera in north eastern Iran in 2005-2007, Eviphis cultratellus (Berlese, 1910) reared and identified from Scarabaeus sacerL. Phoretic deuotonymphs, females and males extracted from the neck of the beetle hosts which were captured by light trap in Sarakhs, Feizabad and Taibad regions (Khorasan Razavi province). These mites feed on nematodes and some of them distribute by means of phoresy to access a new habitat.
Adults and deutonymphs are pink in color; idiosoma nearly hemispherical; marginal setae thick and lanceolate; posteroventral seta of coxa II and III peg-like; peritrematal shield developed to posterior of coxa IV. Female: st1-2 simple and slender; st3, st4 and genital setae peg-like; idiosomal length 900 µm and width 750 µm. Male: sternoventral shield bearing 5 pairs of setae and 3 pairs of pores; st1-2 simple and slender; st3-5 peg-like; idiosomal length 840 µm and width 670 µm. Deutonymph: sternoventral shield bearing 5 pairs of setae; st1 simple and st2-5 peg-like; idiosomal length 715 µm and width 520 µm.
