Ibotyporanga naideae – Huber 2000: 94, figs 38–39, 60, 78, 104, 109, 128, 174, 357–366 (♂ ♀). — Carvalho & Avelino 2010: 6. — Astrin et al. 2007: table 1 (molecular data). Diagnosis Males are easily distinguished from most known congeners (except I. kanoe sp. nov. and I. diroa) by long and slender procursus without dorsal branch (Fig. 62A–C); from I. kanoe and I. diroa by long cheliceral apophysis directed upwards (Fig. 63A–D) and by details of genital bulb: strongly developed retrolateral tubercles (Fig. 11E–F) and tip of embolus with small pointed dorsal process (arrow in Fig. 62F); from I. diroa also distinguished by presence of prolateral process proximally on procursus (arrow in Fig. 62B) and by very short and indistinct prolateral sclerite on bulbous part of genital bulb (Fig. 62D). Females differ from known congeners by relatively long and narrow epigynum with very indistinct, weakly curved anterior pocket (Fig. 64A–C); from most congeners (except I. sertao sp. nov.) also by pair of long tubes in internal genitalia (Figs 63F–H, 64G–H) (present but much shorter in the similar I. kanoe). Remark We found considerable variation among specimens from different localities, concerning mainly size (body size, leg length, male palp and female epigynum size) and the length of the male cheliceral apophysis (see Variation below). Some of this variation may indicate species limits. We do not split this species for several reasons. First, in its current circumscription, the species is easily diagnosable by numerous morphological details, especially when males are available. A split into two or more species would currently result in poorly diagnosable species. Second, topotypical males are not available. The males from Maranhão listed below are from localities more than 600 km from the type locality in Pará. Third, while there are quite substantial differences between the extremes, i.e., between the most northern (Maranhão) and most southern (Mato Grosso do Sul) specimens, our limited sample of intermediate localities suggests that this may be a clinal, continuous variation. We thus suggest that this species should not be split until more data become available, in particular: (1) topotypical males; (2) samples from further localities in poorly sampled regions like Mato Grosso and Goiás; (3) molecular sequence data from specimens across the entire geographic range.
