Diagnosis

Males of P. caatinga resemble those of P. microzoporus , P. curtipes Schubart, 1960 , and P. leopoldoi by having gonopod with subtriangular internal branch, and solenomere with ectal and apicomesal processes ( Fig. 57D–F ). Pseudonannolene caatinga can be distinguished from those species by having a distal projection on the internal branch ( Fig. 57D ).

Etymology

Noun in apposition, taken from the semi-arid biome ‘Caatinga’ where the species is widely distributed ( Iniesta & Ferreira 2014).
