Diagnosis. Compared to all the described species of Microbianor (see Logunov 2000), M. deltshevi sp. n. differs in having a straight embolus ( Fig. 20 ) and dark brown femora and tarsi I ( Fig. 17 ) in males and the complete absence of fossae in females ( Fig. 22 ).

Etymology. The new species is dedicated to Prof Christo Deltshev ( Bulgaria), for his life-long dedication to, and effective work on, spiders, and on the occasion of his 70 th anniversary.

Distribution. NE part of Madagascar (Tamatave).
