Type material

Holotype female: BRAZIL, Paraíba. Probably Campina Grande. Tranqüilino Leitão leg. Museu Nacional, Rio de Janeiro (13898), not examined.

Remarks

Hapalotremus exilis was described by a single female from Campina Grande (Paraíba) ( Figure 4 ) and the type material has been listed as ‘not located’ in the annotated check list by Silva-Moreira et al. (2010) of Arachnida type specimens deposited in the Museu Nacional, Rio de Janeiro. According to the geographical distribution and many of the morphological characteristics from the original description, such as the small size of the female and the reduced number of labial and maxillary cuspules, together with the shape of the spermathecae presented by Bücherl et al. (1971) and Schmidt (2002) it could be a junior synonym of Oligoxystre ( Guadanucci 2011) or Guruyita ( Guadanucci et al. 2007) ( Ischnocolinae ). Unfortunately, the original description does not warrant recognition of the species, and, therefore the identity of H. exilis cannot be confirmed. The species is here considered species inquirenda, pending the finding of the type material or availability and careful examination of material from the type locality.
