Fig. 7 a, b

Material examined.

Bulgaria • 2 ♂♂, 1 ♀, Pirin Mountains, Hut Kamenitsa , 1800 m a. s. l., 15. 06. 1988, P. Beron leg.

Taxonomic notes.

Observations under the microscope of the studied material have shown several previously unknown features not mentioned in its original description ( Condé 1956, 1966). The antennae have 27 antennomeres in a 3.8 mm female, and 25 in 3.95 mm and 4.2 mm males. The apical antennomere has four simple spheroidal olfactory chemoreceptors on the cupuliform organ. A large bacilliform sensillum is present on the third antennomere in tergal position (between b-c macrosetae). Notal tergites bear microdenticles, and the clothing setae are either smooth or have a distal tiny barb (Fig. 7 a ). The marginal setae are slightly longer and thicker than clothing setae, with a few bars on distal half to two-thirds. The pronotal macrosetae have a few thin tiny barbs on the distal half, with the longest lp macrosetae with one or two thin tiny barbs at the distal position. No trochanteral setae were observed in any of the specimens studied.

The male urosternite I (Fig. 7 b ) features slightly spherical appendages, each with an apical field containing ≤ 40 glandular a 1 setae; a continuous posterior field of ~ ≤ 240 g 1 glandular setae arranged in 7–9 rows.

Remarks.

New record for Bulgaria.

Habitat and distribution.

A soil-dwelling species that inhabits high altitudes. It is known from two localities in the Austrian Alps ( Condé 1954, 1966) and a single locality in the Pirin Mountains of Bulgaria.
