Selenogyrus foordi  Sherwood, Henrard & Spiegel, 2024.  DOI: 10.3897/afrinvertebr.64.113946

 

A new spider species, Selenogyrus foordi sp. nov. (♂♀), is described from Mount Nimba, Guinea. Consequently, we provide the first in vivo photographs of a selenogyrine in the scientific literature and the first record of Selenogyrinae Smith, 1990 from Guinea. We also record S. aureus Pocock, 1897, described from Sierra Leone, from Massif du Ziama Biosphere Reserve, Guinea, representing the second known species for this country.  

Key words: distribution, morphology, spider, tarantula, taxonomy

Diagnosis: Males of Selenogyrus foordi sp. nov. can be distinguished from S. aureus by the thinner apical taper of the embolus (embolus wider at apex in S. aureus) and the presence of darkened femora and white markings on the distal third tibiae in vivo (femora with golden tinge and lacking white markings on the distal third of the tibiae in S. aureus). Females of S. foordi sp. nov. can be distinguished from S. africanus, S. austini, and S. caeruleus by the medially flared receptacles of the spermathecae (not medially flared in S. africanus, S. austini, and S. caeruleus).

Etymology: The specific epithet is an eponym honouring our colleague the late Stefan Foord (1971–2023), in recognition of his significant contributions to African arachnology, and in remembrance of his kind and collaborative spirit.
