Mortoniella (Nanotrichia) pacuara ( Flint, 1974)

Fig. 83

Mexitrichia pacuara Flint 1974: 11 ; Flint et al. 1999: 27 [distribution].

Mortoniella pacuara (Flint) : Blahnik and Holzenthal 2008: 39 [reillustration, redescription, member of ormina group].

This species was redescribed in Blahnik and Holzenthal (2008) and the reader is referred to that publication for a description. It is refigured in the current paper for comparative purposes. Mortoniella pacuara is generally similar to M. aries (Flint) , M. paucispina , n. sp., and M. zamora , n. sp., as noted in the diagnoses for those species, but is easily recognized by the large rounded, saddle-like, lateral protrusions of the dorsal phallic spine and the distinctly recurved apex of the same structure.
