No. of bitstreams: 0 Previous issue date: 2020-11-16 Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) This study describes the main ontogenetic changes in the armored catfish Pterygoplichthys ambrosettii from newly hatched larva to adult. The relationship between the degree of development of newly hatched larvae and post-larvae and parental care is discussed. Ontogenetic series containing newly hatched larvae, post-larvae, and juveniles of P ambrosettii were obtained from the Fish Culture Station of Universidade Estadual Paulista. Adult specimens were collected from the Preto River in the upper Parana River basin. Morphological, osteological, morphometric, and meristic data and color pattern were analyzed. The species exhibited indirect development, with a distinct post-larval stage after the larval stage. Newly hatched larvae had a well-developed yolk sac and lacked pigmentation. The following characters underwent less change during development and can therefore be useful in taxonomical analyses: odontodes located posteriorly to the preopercle, number of plates on the lateral line, lower lip with three series of papillae, spots on the upper ray of the caudal fin, caudal fin similar to that of the adult, body ventrally covered with dermal plates and odontodes, small irregular spots on head, and typical ventral color pattern of the adult. The morphometric data revealed that most variation in body proportions occurred during less advanced developmental stages. Parental care influenced the ontogenetic development of newly hatched larvae.

Fins translucent or light brown, darker basally. Caudal peduncle with a longitudinally elongated light brown spot (Figs. 1–3). From a subsample of 38 specimens, ranging from 27.3 to 119.8 mm SL, a total of 20 (52.6%) specimens showed the herein called coloration pattern or phenotype I (i.e., body light brown with a black lateral band; Figs. 2A–C, E); 12 (31.6%) specimens showed the coloration pattern II (i.e., body light brown uniform, without a black lateral band or spots); and six (15.8%) specimens showed the coloration pattern III [i.e., body light brown without a black lateral band but with several small (less than eye diameter) dark brown spots on dorsal surface and sides, more evident in the posterior half of the body]. In small specimens (less than 65.0 mm SL; n = 18) the coloration pattern I was dominant (83.3%; i.e., 15 specimens), while no specimens with the coloration pattern II where recorded; only 16.7% (three specimens) showed the coloration pattern II. In medium-sized specimens (65.0–100.0 mm SL, n = 14), the coloration pattern II was the least frequent (21.4%; i.e., three specimens); whereas the coloration patterns I and III were displayed by 5 (35.7%) and 6 (42.9%) specimens, respectively. On the other hand, the color pattern III was displayed in all large specimens (more than 100.0 mm SL; n = 6). Such results could suggest an ontogenetic change in the coloration pattern from state I, predominant in small (juvenile) specimens, to state III, predominant in large (adult) specimens, condition that has already been reported in other congeneric species [see da Silva et al. (2010) and Nascimiento et al. (2017)]. Color in life. Body brown, light brown, yellowish or light orange, darker on dorsal surface, and paler ventrally, usually with a continuous black lateral band (of variable thickness), extending from opercle to caudal-fin base. Lateral band absent in some specimens, having a coloration pattern more or less uniform (usually light brown or yellowish) with or without small (less than eye diameter) dark brown spots on dorsal surface and sides. Paired, dorsal and anal fins light brown, yellowish (usually darker at base) or translucent; caudal fin brown or yellowish, usually darker than other fins. Caudal peduncle with a longitudinally elongated light brown to black spot (Fig. 3). Geographic distribution. Trichomycterus striatus was originally described from the Cana River (Tuyra River basin) in eastern Panama, later being recorded in most of the main river basins in both the Pacific and Atlantic versants of the country (Behre 1928, Hildebrand 1938, Loftin 1965, Smith & Bermingham 2005). This species has also been reported from Costa Rica (Bussing 1967, 1998, Angulo et al. 2013), along the Pacific slope from the Térraba and Coto River basins, making it the trichomycterid species with the northern-most distribution. Specimens collected in Uvita, Puntarenas, Costa Rica (DZSJRP 21188; Fig. 3) represents the first documented record of the species in the Pirrís River basin, sensu Angulo et al. (2015), which expands, slightly, the northern geographic limit of the species (genus and family) in lower Central American waters (Fig. 9). On the other hand, there are numerous records of occurrence of T. striatus in Colombian waters [e.g., Eigenmann (1918), Mojica-C. (1999), Maldonado-Ocampo et al. (2005, 2008, 2012), Ortega-Lara et al. (2006), Villa-Navarro et al. (2006), Jaramillo-Villa et al. (2008), Castellanos-Morales & Galvis (2012), among others]; however, the examination and direct comparison of specimens collected from both the Atrato and Magdalena River basins identified as T. striatus with specimens from Panama and Costa Rica, have revealed some morphological differences, raising doubts on the actual occurrence of the species in Colombia. The resolution of the taxonomic status of the Colombian populations of T. striatus is currently under study by one of the authors (CD), thus we herein opt to defer the inclusion of these previous records of T. striatus from Colombian river basins. Ecological notes. Trichomycterus striatus inhabits forest brooks and creeks, of low to moderate current velocity, with bottoms consisting mainly of sand or small to medium sized rocks, with periphytic and/or submerged vegetation usually present (Bussing 1998). In Costa Rica, T. striatus has been reported at elevations ranging from 20 to 660 m (Bussing 1998, Angulo et al., Published as part of Angulo, Arturo, Donascimiento, Carlos, Lasso-Alcalá, Oscar M., Farah-Pérez, Aldo, Langeani, Francisco & Mcmahan, Caleb D., 2018, Redescription of Trichomycterus striatus (Meek & Hildebrand, 1913) (Siluriformes: Trichomycteridae), with notes on its geographic distribution, pp. 530-550 in Zootaxa 4420 (4) on pages 532-541, DOI: 10.11646/zootaxa.4420.4.5, http://zenodo.org/record/1251003, {"references":["Meek, S.

This study investigated the morphology, morphometric and meristic characters of 117 larval Pimelodus britskii showing early development of head, eye, barbel and snout. Body and mouth pigmentation increased throughout development; the mouth was ventrally situated in the yolk-sac stage, becoming subterminal afterwards, and an embryonic fin was visible in all four stages observed. Post-flexion larval P. bristskii are distinguished from larval P. ortmanni by having 47-50 myomeres (v. 36).

Oyakawa, M. Toledo-Piza, I. Fichberg, C. Chamon. Diagnosis. Microlepidogaster negomata differs from all congeners by having two to five unperforated platelets on skin covering swimbladder opening, anterior to the median lateral series of plates (Fig. 2) (vs. absence of these platelets in M. discontenta, M. discus, M. longicolla, and M. perforata; and none or one platelet in M. arachas and M. dimorpha); and ventral laminar expansion of coracoid enclosing totally or almost totally the arrector fossa of pectoral girdle (Fig. 3 E) (vs. ventral laminar expansion of coracoid enclosing partially the arrector fossa, Fig. 3 A���D). In addition, M. negomata can be distinguished from all congeners, except for M. discus, by having the ventral laminar expansions of cleithrum and coracoid bearing 20���35 odontodes restricted to the lateral portion of pectoral girdle (vs. more than 35 odontodes, generally around 100, reaching the middle portion of pectoral girdle). The following features are also useful to diagnose M. negomata within the genus: snout with many irregularshaped platelets, eventually with a naked area at the most anterior portion (vs. snout broadly naked anteriorly in M. discontenta and M. longicolla; snout with paired rostral plate in M. dimorpha and M. perforata; and snout with variable coverage of plates, from many platelets to a pair of rostral plates in M. arachas); iris operculum present (vs. absent in M. perforata); pectoral axillary slit present only in juveniles (vs. pectoral axillary slit persistent, in both juveniles and adults in M. dimorpha and M. perforata); odontodes at anterior plates of snout small and slightly pointed (vs. leaf-shaped odontodes in M. dimorpha and M. perforata); anterior portion of compound supraneural plus first dorsal-fin proximal radial contacting the neural spine of the eighth or ninth vertebra (vs. seventh vertebra in M. discus and M. dimorpha, tenth vertebra in M. discontenta, and tenth or eleventh vertebra in M. longicolla); mid-dorsal lateral series of plates surpassing the vertical through the end of dorsal fin (vs. mid-dorsal lateral series reduced, never surpassing that point in M. longicolla and M. perforata); median series of lateral plates complete, reaching the end of the caudal peduncle (vs. median series of lateral plates terminating two plates before the end of the caudal peduncle in M. perforata); and first anal-fin pterygiophore covered by skin only, not bearing odontodes (vs. bearing odontodes in M. dimorpha and M. perforata). Description. Morphometric and meristic data given in Tables 1 and 2. Dorsal body profile slightly convex from tip of snout to tip of parieto-supraoccipital; almost straight to caudal-fin origin. Ventral body profile almost straight from tip of snout to pelvic-fin origin; ascending from pelvic-fin origin to end of anal-fin base; straight to caudal-fin origin. Greatest body depth variable, at parieto-supraoccipital tip or at dorsal-fin origin. Greatest body width at posterior margin of opercle, gradually tapering towards to caudal fin. Caudal peduncle ellipsoid in transverse section, slightly flattened dorsally and ventrally. Anterior margin of snout rounded in dorsal view; tip of snout bearing many small irregular-shaped plates, or with naked areas at most anterior portion (more evident in juveniles). Eye small, dorsolaterally placed. Iris operculum present. Compound pterotic quadrangular in shape, its posterior extension poorly-developed, not reaching to rib of sixth vertebra; compound pterotic fenestrae irregular in shape and variable in size, smaller in dorsal and larger in ventral portion of bone. Infraorbital canal entering infraorbital series via sphenotic. Parietosupraoccipital not forming dorsal wall of swimbladder capsule. Odontodes on head and body small and slightly pointed, not forming conspicuous rows. Bony crests and hypertrophied odontodes on parieto-supraoccipital and compound pterotic absent. Lips oval, papillose; lower lip not reaching pectoral girdle; papillae gradually smaller toward lip edges. Maxillary barbel reduced, free from oral disk. Teeth slender and bifid; median cusp larger and rounded, lateral cusp smaller and pointed. Premaxillary teeth 16���26 (19). Dentary teeth 14���25 (22). Accessory teeth present only in juveniles. Dorsal-fin rays II,6���7; originating approximately at vertical through end of pelvic-fin base; tip of adpressed rays almost reaching vertical through end of anal-fin base; spinelet small, somewhat elliptical in shape, locking mechanism non-functional. Anterior portion of compound supraneural plus first dorsal-fin proximal radial contacting neural spine of eighth or ninth vertebra. Supraneural anterior process absent. Pectoral-fin rays I,6; originating immediately behind opercular opening; tip of adpressed rays reaching to vertical through end of pelvicfin base. Pectoral-fin unbranched ray without ossified segments distally. Cleithrum and coracoid only exposed laterally, restricted to area near to pectoral-fin insertion, with lower number of odontodes (20���35) compared to congeners; remaining portions of pectoral girdle covered by skin and abdominal plates. Arrector fossa totally or almost totally enclosed. Pectoral axillary slit present only in juveniles. Pelvic-fin rays i,5; unbranched ray shorter than branched rays. Anal-fin rays i,5. Caudal-fin rays i, 13-15(14), 1; concave; lobes equal in size; 3���5 (4) dorsal and 2���5 (3) ventral procurrent rays. Adipose fin absent; some specimens with one or two rounded or elongate azygous plates in place of adipose fin. Body entirely covered by dermal plates, except for ventral part of head, region overlying opening of swimbladder capsule, around pelvic-fin origin, and region anterior urogenital opening. Abdomen entirely covered with small-sized plates irregularly distributed; lateral abdominal plate series absent. Mid-dorsal series of lateral plates surpassing vertical through end of dorsal fin. Median lateral plate series complete and uninterrupted with 27��� 31 (29) plates. Two to five reduced unperforated platelets on skin covering swimbladder opening, anterior to median series of plates. Vertebrae 32 (32). Ventral lateral plates 22(3), 23(5), 24(3), 25(12), 26(11)*, 27(3), 28(2), 29(6), 30(1) 22���30 25 Premaxillary teeth 16(1), 17(0), 18(4), 19(10), 20(6), 21(1), 22(5), 23(6)*, 24(4), 16���26 19 25(1), 26(1) Color in alcohol. Ground color of head and body light-brown on dorsal, lateral and ventral portions. Head dark brown along parieto-supraoccipital and area from anterior border of snout to eye. Rectangular, longitudinally elongate, dark-brown blotch between compound pterotic and posterior portion of cleithrum process and plates at mid-ventral series. Dark brown lateral stripe inconspicuous in most specimens, approximately two plates wide, extending from anterior portion of snout and fading on caudal peduncle. Four dorsal dark brown blotches, conventionally arranged as other congeners; more conspicuous in melanic specimens. Pectoral, dorsal, pelvic, and anal fins mostly hyaline, with tiny light-brown chromatophores along rays. Caudal fin almost entirely dark brown, except for distal tip of rays and a hyaline blotch in each lobe; greater specimens with blotches inconspicuous, darkened. Sexual dimorphism. Males with conspicuous urogenital papilla immediately posterior to anus (vs. absent in females) and also with a dermal flap on dorsal surface of unbranched pelvic ray and first branched pelvic-fin rays (vs. absent in females). Males with longer pelvic-fin extending to or surpassing anal-fin origin (vs. pelvic-fin never reaching anal-fin origin in females). Distribution. Microlepidogaster negomata is known from the Ribeir��o Bebedouro and Rio Curral das ��guas, Rio Abaet�� drainage, tributary to left side of the Rio S��o Francisco, Minas Gerais state, southeastern Brazil (Figs. 4 and 5). Ecological notes. The type locality of Microlepidogaster negomata (Fig. 5) is a very small stream near the Arapu�� municipality, in a stretch between 912 to 1032 meters above sea level. The stream is about 0.8 m wide, up to 0.4 m deep, with bottom composed of gravel, stones, and sand. The riparian vegetation is mainly composed of grasses and herbs and surrounded by a grazing area with a few palms and shrubs, which favors bank erosion and great penetration of light. Microlepidogaster negomata was collected mainly associated with marginal vegetation and other species collected in the same stream include Astyanax bimaculatus (Linnaeus, 1758) (DZSJRP 20137), A. rivularis (L��tken, 1875) (DZSJRP 20126), Cetopsorhamdia iheringi Schubart & Gomes, 1959 (DZSJRP 20131), Harttia sp. (DZSJRP 20129), Imparfinis sp. (DZSJRP 20133), Parotocinclus prata (DZSJRP 20130), Trichomycterus sp. 1 (DZSJRP 20136), and Trichomycterus sp. 2 (DZSJRP 20132). Etymology. The specific epithet, negomata, is in reference of a locality in Ribeir��o Bebedouro where the species was captured, the Fazenda Nego Mat��. The denomination, Nego Mat��, was the nickname of the former owner of the farm, Mr. Esli Domingues.
