03E83A01FFBCFFD0FC087DE7FE2FFC23.taxon	distribution	Distribution. Probolodus heterostomus is known to occur in the tributaries of rio Paraíba do Sul basin, southeastern Brazil (Fig. 2). Ecological notes. Probolodus heterostomus was studied by Sazima (1977; 1983) because of its habit of tearing off and eating scales of other fishes. Pieces of leaves, insects and scales were observed in the mouth of many specimens preserved in alcohol (MZUSP 44110, 5, 40.2 - 46.7 mm SL; MZUSP 7904, 6, 42.3 - 56.6 mm SL). However, ctenoid and many cycloid fish scales were found in the stomach contents and between gill rakers of the cleared and stained specimens (LIRP 6296, 2, 72.7 - 88.5 mm SL; ZUEC 5498, 2, 77.3 - 100.8 mm SL).	en	Santos, Osmar, Castro, Ricardo M.

03E83A01FFBCFFD0FC087DE7FE2FFC23.taxon	discussion	Remarks. Roberts (1970) examining stomach contents of some lepidophagous characids, such as Catoprion, Exodon, Roeboides, and Roeboexodon, was the first author to observe a large number of scales in the stomachs of specimens of Probolodus heterostomus and commented on the absence, until then, of knowledge about the relationships among the lepidophagous genera aforementioned (see more details about the lepidophagous taxa in Sazima, 1977; Géry, 1980; Sazima & Uieda, 1980; Sazima & Machado, 1982; Sazima, 1983; Vari, 1986; Janovetz, 2005). Still, Roberts (1970) considered the genus P. heterostomus very similar to the tetras of the genus Astyanax. Therefore, Géry (1977) based in Eigenmann (1911, 1915) and Roberts (1970), considered P. heterostomus morphologically very similar to the tetras of the genus Astyanax, especially A. fasciatus, but both with different dentitions. According to the cited author, the tricuspidate teeth of P. heterostomus are few in number and directed outward, especially on the prominent dentary, enabling it to remove rows of scales of other fishes, possibly from the bottom up. However, Sazima (1977) suggested that A. fasciatus is the main prey of P. heterostomus, which are externally very similar and sympatric species occurring in the drainage of the rio Paraíba do Sul. In addition, Sazima (1977; 1983) hypothesized that the similarity between these two genera is a form of disguise or aggressive mimicry.	en	Santos, Osmar, Castro, Ricardo M. C.

03E83A01FFB8FFDFFE837CE8FE48FBEC.taxon	distribution	Distribution. Probolodus oyakawai is known to occur in the rio Ribeira de Iguape basin, southeastern Brazil (Fig. 2). Ecological notes. Ctenoid and cycloid fish scales were observed in the stomach contents of three P. oyakawai specimens (MZUSP 53499, 2, 31.7 - 64.3 mm SL; MZUSP 55006, 1, 37.9 mm SL). No other item could be identified, possibly due to their advanced state of decomposition.	en	Santos, Osmar, Castro, Ricardo M. C.

03E83A01FFB8FFDFFE837CE8FE48FBEC.taxon	etymology	Etymology. The species name, oyakawai, is in honor of Osvaldo T. Oyakawa from MZUSP, the collector of many of the specimens that served as the basis of this paper, in appreciation of his major contributions to our knowledge of the fishes of the rio Ribeira de Iguape basin.	en	Santos, Osmar, Castro, Ricardo M.

03E83A01FFB8FFDFFE837CE8FE48FBEC.taxon	discussion	Remarks. Probolodus oyakawai has been previously cited as P. heterostomus by various authors who have studied specimens collected in the rio Ribeira de Iguape basin (see synonymy). However, as shown on the item “ Ecological notes ”, P. oyakawai also shows preference by fish scales. Thus, as hypothesized by Sazima (1977), Astyanax fasciatus is not found over the entire range of Probolodus, being probable that in other drainages there is an association with other similar species of Astyanax. In the rio Ribeira de Iguape basin, A. ribeirae is a likely candidate, as Deuterodon iguape, which also have the general appearance of Astyanax (Sazima, 1977; Oyakawa et al., 2006).	en	Santos, Osmar, Castro, Ricardo M.

Dorsal-fin origin situated along vertical located approximately at middle of SL. Origin of adipose fin located slightly anterior of vertical through posterior terminus of base of anal fin. Profile of adpressed pectoral fin distinctly acute. Tip of pectoral fin extending approximately to vertical through insertion of pelvic fin. Profile of expanded pelvic fin pointed, with first branched ray either longest in fin or subequal to unbranched ray. Insertion of pelvic fin located distinctly anterior to vertical through origin of dorsal fin. Tip of adpressed pelvic fin extending approximately to vertical through insertion of anal fin. Some larger, apparently male, specimens with posteriorly-directed hooks along posterior margins of second through seventh pelvic-fin rays; hooks rarely also present on first ray. Hooks limited to posterior branch of hook-bearing rays. Each hook-bearing segment typically with one hook, although two hooks occasionally present on some segments. Distal margin of anal fin slightly concave in which fourth or fifth unbranched and first and second branched rays longest and subequal or first through third branched rays longest with subsequent branched rays gradually decreasing in length. Some larger, apparently male, individuals with hooks present on various rays gradually of anal fin. Hooks most often arise along posterior margin of posterior branch of second through seventh branched rays. Hooks extending onto unbranched segments of some rays. Caudal fin forked, with distal margins of lobes obtusely pointed. Color in alcohol. Overall ground color of body in specimens fixed in formalin yellowish brown. Guanine remaining on lateral and ventral portions of head and on ventral and, to a variable degree, lateral surfaces of body. Snout and dorsal portion of head relatively dark. Middorsal and immediately adjoining portions of body relatively dark. Distinct, wedge-shaped, ventrally-attenuated humeral blotch with irregular margins extending from approximately five scales dorsal of lateral line to about two scales ventral of lateral line. Pigmentation of humeral blotch typically most intense in region dorsal of lateral line, with pigmentation of remaining ventral portion of blotch variably lighter, but still quite obvious. Dark midlateral pigmentation more conspicuous on portion of body beginning at vertical through anterior portion of dorsal fin, with stripe widening posteriorly on caudal peduncle into distinct, horizontally-elongate, ovoid blotch. Pigmentation of blotch more intense than that of remainder of stripe. Chromatophores of dorsal portion are concentrated at the base and middle region of the scales, its margins being free of chromatophores. Region below the lateral line decreases the concentration of chromatophores, and, between the anal fin and caudal peduncle, sparse chromatophores are present in greater proportion. Dorsal, anal, and caudal fins with interradial membranes covered by small dark chromatophores, with chromatophores often more concentrated proximate to margins of fin rays. Dark pigmentation on caudal fin more intense along middle fin-rays in most specimens and forming stripe variably continuous anteriorly with midlateral dark blotch on caudal peduncle. Anal fin with unbranched rays and all branched rays pigmented. Distal half of remainder of fin with dark chromatophores in all individuals, with fields of chromatophores extending nearly to base of fin membranes. Adipose fin lightly colored overall, but often freckled with small dark spots. Pectoral and pelvic fins with small, dark spots located both along fin-ray margins.	en	Santos, Osmar, Castro, Ricardo M.

03E83A01FFB7FFDBFE867B92FDC9FBCB.taxon	distribution	Distribution. Probolodus sazimai is known to occur in the rios Itapemirim and Doce basins (Espírito Santo and Minas Gerais states, respectively), southeastern Brazil. (Fig. 2). Ecological notes. Ctenoid and cycloid fish scales were observed in the stomach contents and between gill rakers of one specimen (MCP 13813, 1, 43.5 mm SL). No other items could be identified, possibly due to their advanced state of decomposition. Leaf fragments, insects and scales were observed in the oral cavity of three specimens preserved in alcohol (LBP 3433, 1, 45.1 mm SL; MCP 13813, 2, 36.8 - 54.4 mmSL).	en	Santos, Osmar, Castro, Ricardo M.

03E83A01FFB7FFDBFE867B92FDC9FBCB.taxon	etymology	Etymology. The species name, sazimai, is in honor of Ivan Sazima from Museu de Zoologia of UNICAMP (ZUEC-PIS), in appreciation of his contributions to our knowledge of the Neotropical lepidophagous caraciforms. Notes on phylogenetics relationships and biogeography of Probolodus The monophyly of Probolodus is supported by five exclusive characteristics, and three non-exclusive characteristics. Of all the characteristics shared among species of the genus, there are at least two exclusive characteristics, such as the presence on premaxillary and dentary of tricuspid teeth, with median cusp greatly developed and pointed outward, most probably related to the lepidophagous habit these species (Fig. 1 a-c). The genera of Neotropical characiforms Bryconexodon, Catoprion, Exodon, Roeboexodon, Roeboides, and Serrabrycon also exhibit specialized dentitions favoring the lepidophagous habit, such as pointed by Sazima (1977), Sazima & Uieda (1980), Sazima & Machado (1982) and Sazima (1983). However, specialized teeth directed out of the mouth is a diagnostic characteristic which allows easy recognition of lepidophagous taxa, although, the shape, number and the differential arrangement these conical and mammiliform, or cuspidate teeth on premaxillary, maxillary and dentary in these species are fundamental for understanding of evolution this character in independent lineages of Neotropical lepidophagous characiforms, as demonstrated by some authors (e. g., Roberts, 1970; Géry, 1980; Sazima, 1983; Vari, 1986; Lucena, 1998; Mirande, 2010; Mattox & Toledo-Piza, 2012). Thus, the specialized dentition of Probolodus, as well as the predatory behavior of plucking and eating scales could have evolved independently in Bryconexodon, Exodon, and Roeboexodon. Among the shared characteristics that support evolutionary relationships among these three taxa, we highlight some related to the structure and arrangement of teeth, mainly: the teeth of these characids are stout with hypertrophied bases, conical, and especially in the dentary, the larger teeth have compressed and cuspidate crowns, being unicupidate or bicuspidate and directed upwards; larger cuspidate teeth arranged with conical smaller teeth, and are recurved posteriorly relative to the body; in the premaxillary there is a outward mammiliform tooth developed and directed forward. Probolodus has been treated as a monophyletic group of lepidophagous characids evolutionarily related to the Tetragonopterinae (sensu Roberts, 1970; sensu Géry, 1977; 1980; and sensu Mirande, 2010). Thus, the hypothesis of Sazima (1977), considers the similarity of Probolodus with the Tetragonopterinae (sensu Géry, 1977) a form of aggressive mimicry, (i. e., similarity due to mimicry and not to phylogenetic proximity), whereas the Tetragonopterinae (sensu Géry, 1977), Astyanax fasciatus and coastal sympatric species of the genus Deuterodon are probably the usual prey of the species of Probolodus. The species of the genus Probolodus are distributed throughout the coastals drainages of eastern Brazil (from Espírito Santo to São Paulo states) which according to Ribeiro (2006) corresponds to an area of great biogeographical significance due to high degree of endemism in its fish fauna (Fig. 2). Meanwhile, the eastern coastal systems have already been considered as areas of endemism by various authors (e. g., Eigenmann, 1909; Géry, 1969; Vari, 1988; Weitzman et al., 1988; Menezes, 1996) and recognition of these areas in the coastal drainages of South and Southeast of Brazil is similar or quite congruent with the distribution of the genus Deuterodon by Lucena & Lucena (1992; 2002) and Pereira (2010), Mimagoniates by Menezes & Weitzman (1990), Spintherobolus by Weitzman & Malabarba (1999), Hemipsilichthys by Pereira & Reis (2002), Hollandichthys by Bertaco (2003), Phalloptychus by Lucinda (2005), Phalloceros by Lucinda (2008). However, the coastal streams have been historically connected with the adjacent upland crystalline shield. Thus, geological events were responsible to the capture of adjacent upland high areas, and consequently the capture of upland streams, such as the formation of the upper rio Paraíba do Sul by capturing streams of the rio Tietê (cf., Ab’Saber, 1957; Menezes, 1972; Weitzman et al., 1988; Langeani, 1989; Bizerril, 1994; M. Malabarba, 1998; Weitzman & Malabarba, 1999; Bizerril & Lima, 2000; Oliveira & Britski, 2000; Quevedo & Reis, 2002; Oyakawa et al., 2005; Ribeiro et al., 2006; Lucinda, 2008). Therefore, possible effects of tectonics, changing the topography of the terrain and, thus, influencing the capture of coastal streams, especially in the southeastern (Ab’Saber, 2003; Cobbold et al., 2001; Ribeiro, 2006) and fluctuations in sea level in the Pleistocene, allowing the union of several rivers and coastal streams, favoring the isolation of populations and speciation events (Weitzman et al., 1988; Weitzman & Malabarba, 1999; Ribeiro, 2006), are, probably, related to the divergence of the species of Probolodus.
