Polydesmus parvulus Porat, 1894: 31 (original description).

Type material.

Syntypes 2 ♀ (NHRM-GULI000069465), Kamerun, Yngve Sjöstedt leg.

Remarks.

Porat (1894) described this species, based on two syntypes deriving from an unspecified locality in Cameroon. We have revised both syntypes and found them to be adult females, one incomplete, the other one complete and with 20 segments ( Fig. 1D ). Since Cameroon appears to support solely species of the trichopolydesmid genus Hemisphaeroparia (24 at the moment), we tentatively transfer the above species to Hemisphaeroparia , comb. nov., even though the spiracles located next to coxa 1 or 2 are not enlarged ( Fig. 1D ). Characteristically enlarged spiracles 1 appear to be restricted to far from all species of Hemisphaeroparia (see below under H. spiniger ). We doubt though that the identity of this enigmatic species will ever be properly established, as superficially the females of most species of Trichopolydesmidae look very much alike. Only the everted vulvae of one of the syntypes might be helpful in the future, but first their comparative study must be accomplished.
