Description

Female

Body elongate oval, up to 2 mm long. Antennae 8–segmented. Legs well developed, without translucent pores; claw with a denticle. Anal apparatus complicated, with inner row of pores, double outer row of spinulae and 6 setae, about two time as long as diameter of anal ring. Ostioles and circuli absent. Multilocular pores numerous, forming groups (each group includes 3–7, mostly 5 multilocular pores, one tubular duct and several simple pores) on all tergites and in marginal zone of thoracic sternites and transverse bands on abdominal sternites. Quinquelocular pores scattered throughout medial zone of venter. Trilocular pores scattered on entire body surface, excluding medial zone of thoracic sternites; dorsal trilocular pores slightly larger than ventral ones; occasional trilocular pores present also in mamelons. Simple discoidal pores scattered on venter and present in dorsal groups with multilocular pores and tubular ducts. Tubular ducts of one size, about two times as long as diameter of multilocular pore, present in dorsal groups (one duct per group), forming transverse rows on abdominal sternites and scattered on thoracic sternites ( Fig. 2 ). Mamelons each with 3–7 stout thick conical setae, several simple pores and occasional trilocular pores, forming a row along entire body margin, a row along midline of dorsum and additionally present in submarginal and submedial zones of thoracic and anterior abdominal tergites ( Fig. 2 ). Minute conical setae sparsely scattered on dorsal surface of body.

Males and larvae

Unknown.

Comments

The new species differs from all congeners in the presence of numerous dorsal groups of wax glands (each with 3–7 multilocular pores, one tubular duct and several simple pores). See the modern identification key for the world fauna of the genus in Gavrilov-Zimin (2016).

All collected females were very young, before oviposition and without eggs inside the body.
