description: <i>Phallotorynus pankalos</i> Lucinda, Rosa, Reis, 2005 <b>Fig. 36</b> Body elongated; greatest depth contained 4.0 to 5.0 and caudal peduncle depth 6.6 to 7.6 times in SL; head length 4.3 to 4.8, predorsal distance 1.5 to 1.6 in SL; snout length 3.3 to 3.9, horizontal orbital diameter 2.2 to 2.8 and least interorbital width 2.1 to 2.8 in HL. Mouth superior; premaxilla with 12 and dentary with 13 teeth. Longitudinal series with 28-30 scales and transverse series with 8 scale rows. Dorsal fin with 8 rays, pectoral fin with 10 or 11, pelvic fin with 5 and anal fin with 10 (males) or 11 (females) rays (Lucinda <i>et al.</i>, 2005; Lucinda, Graça, 2015). Ground color pale brown; scales with dark-brown border, conferring reticulate pattern to body; six to nine dark-brown rounded to irregular spots aligned on lower half of flank, alternated with dark-brown stripes. <b>Maximum standard length.</b> 27.9 mm. <b>Biological data.</b> First maturation size estimated at 18.2 mm SL for females, which possess small fecundity and high mortality rate after the first reproduction (Súarez <i>et al</i>., 2009). <b>Distribution.</b> Only known from córrego Sossego, córrego Mirim and córrego Piraí, rio Iguatemi drainage. <b>Remarks.</b> <i>Phallotorynus pankalos</i> has been captured in the rio Iguatemi drainage, right bank of the upper rio Paraná, since 2000 by Y. R. Súarez and collaborators. Lucinda <i>et al.</i> (2005), in a systematic and biogeographic study of <i>Phallotorynus</i> Henn, 1916, described the new species.Another <i>Phallotorynus</i> species, possibly new according to P.H. Lucinda (in an e-mail, lucinda@mail.uft.edu.br, 2014), was captured in the rio Amambaí, right bank of the upper rio Paraná in 2014, also by Y. R. Súarez and collaborators. This species is similar to <i>P. pankalos</i> in the number of dark-brown spots on flank, but the first ones can be fused, forming a dark-brown stripe. Despite this, only two females were captured, and considering the major importance of males’ gonopodium morphology as diagnostic character, it was not included herein.
