Taxonomy remarks. The male of K. couriae  is characterized by the penial armature with the gonopore elongate, surpassing the hooks, and with an apex forming a globular and membranous structure, ventrally curved, hooks moderately long, and curved ventrally. This species is similar to K. tenebrosa KlapÁlek  , especially in the morphology of the penial armature (see Zwick 1972, fig. 9 AAbout A – BAbout B). Kempnyia tenebrosa  was described from females from ‘TheresÓpolis’ and subsequent authors considered that this material originated from Rio de Janeiro State (RJ) ( Froehlich 2010, 2011; Nessimian et al. 2009). However, Lecci (2013) revising the genus, stated that this locality, ‘TheresÓpolis’ is also an old name for the city of Águas Mornas, Santa Catarina State ( SCAbout SC). Zwick (1972) illustrated two males from Brazil, one from CorupÁ (SC) and another from Tijuca (RJ), even though he observed differences in the length of the hooks and gonophores of these specimens, attributed in part to the teneral condition of the second specimen. Froehlich (2011) examining material from Blumenau deposited in Museu de Zoologia de SÃo Paulo ( MZSPAbout MZSP) concluded that the material belongs to K. tenebrosa  (Froehlich, fig. 5–6). Froehlich (2011) also examined a female of Nedenta fusca NavÁs, 1932 and concluded that this female was also K. tenebrosa  . Froehlich (2011) additionally pointed out that the specimens from Rio de Janeiro are different from specimens from CorupÁ especially in the shape of the gonopore tube. The specimen noted by Zwick (1972, fig. 9A) based on specimen from Rio de Janeiro is similar to K. couriae  , especially in the shape and length of the gonopore tube, the complete base of the penial ring, and by the protuberances at the base of the hooks. It is possible that this male may belong to the new species described herein. Unfortunately, Zwick (1972) did not illustrate the base of the penial ring of specimens from CorupÁ. Recently, Novaes & Bispo (2014, figs. 40–42) found an exemplar of K. tenebrosa in GrÃo  ParÁ (SC) and their illustration are very similar to the figures presented by Zwick (1972) and Froehlich (2011). Unfortunately, specimens of K. tenebrosa  were not included in our molecular analyses, preventing any speculation on the relationship of this species with K. couriae  and other Kempnyia  . Nevertheless, specimens of K. couriae  from RBU are different from K. tenebrosa  illustrated by these authors. Nymphs of K. couriae  are very similar to nymphs of K. reticulata (KlapÁlek)  , but are distinguished by head length, larger in K. reticulata  (head length: 3.7mm—see Avelino-Capistrano et al. 2011) and smaller in the new species (head length: 2.74 mm).
