Opisthacanthus lourencoi Ythier, 2022

Abstract:
A new species of Opisthacanthus Peters, 1861, subgenus Monodopisthacanthus Lourenço, 2001, is described on the basis of six specimens collected in the dry savannah formations of Beraketa, Androy region, in the south of Madagascar. The new species is mainly characterized by a moderate size with a total length of 45-47 mm, a general coloration brownish with some dark variegated zones on the body and metasoma, two vestigial carinae on sternite VII, a genital operculum with an almost oval shape in female, without any incision as its base, leg tarsi with two lateral rows of spines and trichobothrium em2 distal to em1 on patella. The new taxon described here raises the number of known species for the genus Opisthacanthus (Monodopisthacanthus) in Madagascar to 14, and the total number of currently recognized species for the genus to 36.
