Serrapinnus aster is distinguished from all congeners except S. potiguar, by the scimitar-shaped ventral procurrent caudal-fin rays of mature males, almost all of which form a semicircle, resulting in a portion of the ventral procurrent caudal-fin rays having a multi-pointed partial star-shaped margin (Fig. 2a) vs. ventral procurrent caudal-fin rays rod-shaped or spatulate, usually parallel to each other, except for the anteriormost procurrent rays being inclined forward in some species. Furthermore S. aster can be diagnosed from S. potiguar and other species of the genus by the presence of 7–9 cusps on the premaxillary teeth (vs. 5 cusps in S. microdon and S. potiguar, 9 to 11 in S. lucindai, S. sterbai and S. tocantinensis and 10 to 12 in S. gracilis and S. littoris), the incomplete lateral line (vs. complete in S. heterodon), the hyaline dorsal fin (vs. with a proximal black blotch in S. notomelas), and the absence of a black spot on the posteroventral region of the abdomen (vs. the presence of a black spot in that region in S. kriegi).</p> <p>Description. Morphometric data in Table 1. Body short and compressed. Greatest body depth at dorsal-fin origin. Snout slightly pointed in profile. Dorsal profile of head gently convex from snout to anterior portion of supraoccipital bone. Posterior portion of supraoccipital slightly concave. Predorsal profile slightly convex from posterior end of supraoccipital to dorsal-fin origin. Dorsal-fin origin located at midbody. Dorsal profile from base of last dorsal-fin ray to caudal-fin origin straight to slightly convex in females and ventrally arched in preserved mature males. Ventral profile of caudal peduncle straight in females, distinctly convex due to hypertrophy of ventral procurrent caudal-fin rays in males. Caudal peduncle slightly longer than deep. Ventral profile of head and body from tip of mouth to pelvic-fin origin convex, then straight until anal-fin origin on females but slightly concave in mature males. Anal-fin base straight to slightly concave in females, anteriorly convex and distinctively concave posteriorly in mature males.</p> <p>Head relatively small. Posterior margin of opercle sinusoidal with upper portion concave and lower portion convex. Mouth terminal, mouth slit situated immediately below horizontal through middle of pupil. Maxilla angled posteroventrally; posterior tip reaching vertical close to anterior border of eye and horizontal through ventral border of eye. All teeth pedunculated, distally expanded. Premaxilla with 4(1) or 5(1) teeth in single row and bearing 7–9 cusps. Midcentral cusp higher and wider than lateral cusps. Maxilla with 2(2) teeth bearing 5–7 cusps. Dentary with 7(2) large teeth bearing 5 or 7 cusps, followed by one smaller tooth with 3 cusps and one conical tooth. Smaller lateral cusps of dentary teeth sometimes overlapping adjacent tooth cusps; overlap usually absent between posteriormost teeth. All dentary tooth cusps upwardly pointed or slightly directed towards interior of mouth (Fig. 3).</p> <p>Dorsal-fin rays ii,8(1), 9*(16). Dorsal-fin origin at midlength of body. First unbranched dorsal-fin ray about one-half length of second unbranched ray; following branched rays progressively decreasing in size. Adipose-fin origin slightly posterior to vertical through end of anal-fin base. Anal-fin rays iii,16(2), 17*(6), 18(7) or 19(2). First unbranched anal-fin ray only observable in cleared and stained specimens. Distal profile of anal-fin slightly concave in females, deeply concave in males. Last unbranched and first 5–6 branched anal-fin rays longer, remaining rays progressively decreasing in size. Tip of longest anal-fin rays of mature males laterally overlapping last anal-fin rays, and sometimes reaching ventral procurrent caudal-fin rays when caudal peduncle arched. Analfin origin posterior to vertical through base of last dorsal-fin ray. Males with acute, elongate, retrorse hooks, posterolaterally arranged on last unbranched to 8 th, 9 th or 10 th branched anal-fin rays (Fig. 4a). Two unpaired hooks present per lepidotrichia ray segment of on each lateral half of ray. Hooks situated along posterior margin and posterior branches of rays; extending from distal half of proximal lepidotrichia segment to distal end of ray. Hookbearing rays with segments and branches progressively fused with increasing maturation of males. Mature males with hypertrophied soft tissue associated with hook-bearing anal-fin rays. Pectoral-fin rays i,9*(6), 10(9), 11(2). Pectoral-fin ray falling short of pelvic-fin origin in females, but extending beyond that point in males. Pelvic-fin rays i,7*. Pelvic-fin origin anterior to vertical through dorsal-fin origin. Pelvic-fin rays of males with 1 or 2 acute, elongate hooks per lepidotrichia segment. Hooks ventromedially placed on all rays, and associated with hypertrophied soft tissue. Principal caudal-fin rays 18(1), 19*(14). Procurrent caudal-fin rays 11(2) dorsal, 13(2) ventral. Ventral procurrent caudal-fin rays hypertrophied in mature males, extending beyond ventral muscles and skin of caudal-peduncle resulting in multi-pointed semicircular star-shaped structure. Hypertrophied ventral procurrent ray scimitar-shaped: anteriorly bent, proximally acute, expanding distally and ending abruptly in pointed distal tip (Fig. 2a).</p> <p>Scales cycloid, similar in size over all of body. Lateral line partially pored with 6*(2), 8(5), 9(8), 11(1), 13(1) pored scales; scales in lateral line scale row 31(3), 32*(6), 33(4), 34(3), 35(1). Predorsal scales 9(7), 10(6), 11(2), 12(1). Scale rows between lateral line and dorsal-fin origin 5(1) or 6*(16). Scale rows between lateral line row and pelvic-fin origin 4*(16) or 5(1). Scale rows around caudal peduncle 12(1), 13*(8), 14(8). Scales along anal-fin base 6(1), 8*(2), 9(3), 10(6), 11(3), 12(1), 13(1).</p> <p>Supraneurals 4 or 5; abdominal vertebrae 15; caudal vertebrae 19 in two clear and stained specimens.</p> <p>Color in alcohol. Overall background body color yellow (Fig. 1). Head with numerous and large melanophores on dorsal and opercular regions. Small, dark melanophores surrounding mouth opening and over maxilla. Scales on dorsum and on rows above lateral line with subtle reticulated color pattern due to concentration of melanophores along distal border of scales. Body with faint dark midlateral stripe, usually in form of narrow black line along middle longitudinal body axis, beginning anterior to dorsal-fin origin and ending in caudal spot. Body with scattered pigmentation ventral of lateral line. Melanophores aligned along myosepta on posteroventral region of body. Black to brown, rounded spot on caudal-fin base; spot not reaching upper or lower margin of caudal peduncle and extending posteriorly over one-half to two-thirds of middle caudal-fin rays. Dorsal, anal, pectoral and pelvic fins scattered with few melanophores between rays. Adipose fin unpigmented. Caudal fin covered with diffuse dark chromatophores along fin rays, except for clear areas on base of caudal-fin lobes just posterior of caudal-fin spot. No humeral spot; triangular, darkened area in humeral region due to presence of pseudotympanum within musculature.</p> <p>Sexual dimorphism. Sexually mature males with hooks on pelvic- and anal-fin rays, ventrally arched caudal peduncle in preserved specimens; hypertrophied hook bearing anal-fin rays, expanded in sagittal plane usually with fused ray segments; and hypertrophied ventral procurrent caudal-fin rays (Figs. 1, 2a–b, 4a).</p> <p>Distribution. Serrapinnus aster is distributed on the upper portions of the rio Tocantins basin, mainly in the tributaries of the rio Paraná and rio Tocantins (Fig. 5a).</p> <p>Etymology. The species name, aster, refers to the star-shaped ventral profile of the set of hypertrophied procurrent caudal-fin rays present in the mature males of the species.</p> </div>	http://treatment.plazi.org/id/03BCEF20EC01FF9CFF68F9DFFC00423E	Public Domain	No known copyright restrictions apply.

Caudal fin covered with diffuse melanophores along fin rays, except for clear areas at base of each caudal-fin lobe just posterior of caudal-fin spot. Humeral region with triangular, dark area due to pseudotympanum within muscular hiatus (Fig. 8).</p> <p>Sexual dimorphism. Sexually mature males have the following dimorphic characters: the presence of hooks on the pelvic and anal-fin rays; the ventrally arched caudal peduncle; the hypertrophied hook bearing anal-fin rays, expanded in the sagittal plane, and sometimes with a fusion of ray segments; the slightly elongate dorsal- and pelvic-fin rays; and the hypertrophied ventral procurrent caudal-fin rays extending ventrally through the musculature and skin (Figs. 2e–f, 4c, 8).</p> <p>Distribution. Serrapinnus sterbai was described based on aquarium specimens. Zarske (2012) states that the imprecise type locality was the “region of Araguaia, eastern Brazil? (our translation). Our new records extend the distribution of S. sterbai to several tributaries and the main course of the rio Tocantins drainage (Fig. 5c).</p> <p>Remarks. Zarske (2012) figured the holotype, a male specimen, three times in his paper: as a preserved specimen (Zarske, 2012: fig. 1), as a radiograph (Zarske, 2012: fig. 3) and as a live specimen in an aquarium (Zarske, 2012: fig. 4). The three images belong, however, to at least two different specimens, since the shape and profile of the procurrent fin rays in the alcohol preserved specimen is clearly different from that in the radiographed and live specimens. The same seems to occur with the female paratype shown as a preserved specimen in Zarske´s fig. 2 and as a radiograph in his fig. 3, since the body shape and body proportions differ between the figured specimens. The holotype catalogued as UFRJ 8516 was examined and photographed by Fernando R. Carvalho at the Museum für Tierkunde, Dresden. The shape and number of anal fin hooks allowed him to recognize it as the specimen showed in radiograph (Zarske, 2012: 7, fig. 3), but not as the specimen labeled as holotype in Zarske (2012: 6, fig. 1). Examining the radiograph in Zarske (2012: fig. 3) we observe that the second and longest unbranched ray of dorsal fin is anomalous at its midlength and near the tip of the first unbranched ray of dorsal fin. The same anomaly can be seen in the specimen photographed alive in Zarske (2012: 8, fig. 4). Accordingly, specimens labeled as the holotype in Zarke´s figs. 3 and 4 are actually images of the holotype. The specimen erroneously listed as the holotype in Zarske (2012: fig. 1) is a paratype male of MTD F 32658 -32664. The female labeled as the allotypus of fig. 2 in Zarske (2012) also does not correspond to the specimen catalogued as allotype under MTD F 32657, but rather to one of the paratypes at MTD F 32658 -32664.</p> <p>Material examined.

C. Starnes, M. Ribeiro, R. Mendonça, et al.</p> <p>Diagnosis. Serrapinnus tocantinensis can be diagnosed from its congeners by the elongation of the unbranched dorsal and pelvic-fin rays into filaments in mature males. Furthermore S. tocantinensis can be distinguished from S. sterbai by the absence of a continuous mid-lateral black stripe extending from the opercular region to the caudalpeduncle spot, and from the remaining species of the genus by the presence of 9 to 11 cusps in the premaxillary teeth (vs. 5 in S. microdon and S. potiguar, 7 in S. aster, 7 to 9 in S. calliurus, S. heterodon, S. kriegi, S. micropterus, S. notomelas and S. piaba and 10 to 12 in S. gracilis and S. littoris), dentary teeth without expanded cusps forming a sharp cutting edge (vs. dentary teeth with expanded cusps forming a sharp cutting edge in S. heterodon), hyaline dorsal fin (vs. with a proximal black blotch in S. notomelas), and the absence of a black spot on the posteroventral region of the abdomen (vs. the presence of a black spot in that region in S. kriegi).</p> <p>Description. Morphometric data presented in Table 4. Body elongated and compressed. Greatest body depth at dorsal-fin origin. Snout anteriorly rounded in lateral profile. Dorsal profile of head gently convex from vertical through posterior margin of posterior nares to base of supraoccipital spine, then straight to slightly concave to tip of supraoccipital spine. Predorsal profile slightly convex between tip of supraoccipital spine and dorsal-fin origin. Straight to slightly convex along dorsal-fin base. Dorsal profile from insertion of last dorsal-fin ray to adipose fin slightly convex in immatures and females; deeply convex in mature males with ventrally arched caudal peduncle. Dorsal profile straight to slightly concave from adipose-fin base to most anterior dorsal procurrent caudal-fin ray. Distal tip of lower jaw convex. Ventral profile of head straight to gently convex along ventral profile lower jaw to vertical through posterior margin of eye; convex from that point to pelvic-fin origin. Ventral region from pelvic-fin insertion to anal-fin origin slightly concave to straight in immature and females; deeply concave in mature males. Anal-fin base slightly concave in immature and females; distinctly convex anteriorly and straight posteriorly in mature males. Ventral profile of caudal-peduncle slightly concave in females; distinctly convex in mature males due to hypertrophied procurrent caudal-fin rays extending ventrally through muscles and skin (Figs. 2g –h, 10). Caudal peduncle slightly longer than deep; ventrally arched in alcohol preserved mature males. Head anteriorly tapered in lateral view. Posterior margin of opercle sinusoidal with upper portion concave and lower portion convex. Mouth terminal, mouth slit just below horizontal through middle of pupil. Maxilla angled posteroventrally; posterior tip reaching vertical through anterior border of orbit and horizontal through ventral border of orbit.

Dorsal-fin origin slightly anterior to vertical through midlength of standard length. First unbranched dorsal-fin ray about one-half length of second unbranched dorsal-fin ray. Second unbranched dorsal-fin ray longest in fin with branched rays slightly decreasing in size posteriorly. Second unbranched dorsal-fin ray elongated into small filament in mature males. Adipose-fin origin slightly anterior to vertical through base of last anal-fin ray in females and slightly posterior to that point in males. Anal-fin origin posterior to vertical through base of last dorsal-fin ray. Anal-fin rays iii–iv,15*(1), 17(2), 18(19), 19(33), 20(10) or 21(1). Distal border of anal-fin concave; last unbranched and anterior 5–6 first branched rays longest; ray length abruptly decreasing after sixth ray with remaining rays decreasing in size to end of anal fin. Distal tip of longest anal-fin ray of mature males reaching to vertical through base of last anal-fin ray; sometimes reaching ventral procurrent caudal-fin rays when caudal peduncle deeply arched. Males with acute, elongate, retrorse hooks on distal half of anal-fin rays; hooks posterolaterally arranged on last unbranched to 11 th or 17 th branched rays. Two or 3 unpaired hooks per ray segment of each contralateral lepidotrichia (Fig. 4d). Hooks generally situated on posterior margin of posterior ray branches. Hook bearing ray segments and branches progressively fused during maturation of males. Mature males with hypertrophied soft whitish tissue on interradial membrane anterior to analfin hooks. Pectoral-fin rays i,9*(18), 10(36) or 11(13). Pectoral-fin ray reaching pelvic-fin origin in immatures and females, but extending beyond that point in adult males. Pelvic-fin rays i,6(2) or 7*(65). Pelvic-fin origin slightly anterior to vertical through dorsal-fin origin. Pelvic fin falling short of anal-fin origin in immature and females; extending far beyond that point in adult males. Males with one or two acute, elongate, ventral-medially situated hook per lepidotrichia segment on all pelvic-fin rays. Adult males with hypertrophied soft whitish tissue anterior to hooks on ventral surface of pelvic fin. Principal caudal-fin rays 17(2) or 19*(65). Procurrent caudal-fin rays: dorsal 12(2), 13(1) or 15(3); ventral 12(1), 13(2) or 14(3). Adult males with ventral procurrent caudal-fin rays hypertrophied, commonly fused, with distal tips extending beyond muscles and skin of caudal-peduncle. Hypertrophied ventral procurrent caudal-fin rays elongated, rod-shaped, anteriorly bent, proximally acute and slightly expanded distally (Fig. 2g).</p> <p>Scales cycloid; similar in size over all body. Lateral line partially pored with 8(1), 11(5), 12(2), 14(7), 15(4), 16(2), 17(6), 18(2), 19(2), 20(2), 21(1), 23(1), 32(5), 33(7), 34(11), 35*(7) or 36(2) pored scales.

Overall ground coloration of body pale yellow, darker dorsally from head to caudal peduncle. Body with faint dark, sometimes silver, midlateral stripe usually forming black line along middle longitudinal body axis. Longitudinal stripe extending from region slightly anterior to vertical through dorsal-fin origin to caudal spot. Scale series above longitudinal line with darker chromatophores mostly on posterior border of scales, resulting in faint reticulated pattern. Abdominal region ventral to longitudinal line more lightly colored and without pigmentation. Caudal spot rounded, black, situated over posterior of caudal peduncle and base of middle caudal-fin rays, but falling short of upper or lower margin of peduncle. Fins mostly hyaline with scattered, sparse, dark chromatophores. Adipose fin unpigmented. Caudal fin with dark chromatophores along fin rays, except for clear areas on base of each caudal-fin lobe. Humeral region with triangular, dark area due to pseudotympanum in musculature (Fig. 10).</p> <p>Sexual dimorphism. Mature males of S. tocantinensis have hooks on the pelvic and anal-fin rays. The caudal peduncle is ventrally arched, as commonly observed in species of Serrapinnus. The hook bearing anal-fin rays are hypertrophied, expanded in the sagittal plane, and sometimes have fused ray segments. Adult males also have the last unbranched dorsal-fin ray and the first pelvic-fin ray elongated, sometimes in a short filament. The ventral procurrent caudal-fin rays are hypertrophied in mature males, and extend ventrally through the caudal peduncle muscles and skin (Figs. 2g –h, 4d, 10).</p> <p>Distribution. Serrapinnus tocantinensis is distributed throughout the rio Tocantins-Araguaia basin, from the upper to the lower portions of the system (Fig. 5d).</p> <p>Etymology. The species name, tocantinensis, refers to the restricted geographic distribution of the species to the rio Tocantins-Araguaia basin.
