Etymology. I have great pleasure in naming this species after Dr Dmitri Logunov, Curator of Arthropods at the MM, who has always responded very willingly to my many requests for advice and loans.

Remarks. The almost black colour, very short posterior margin of the metaventrum between the metacoxae and the bulbous form of the female spermatheca will distinguish this species.
