Diagnosis. Gephyrocharax chocoensis differs from its congeners by having the posteriormost section of hypaxialis and epaxialis muscles of caudal peduncle well developed and laterally extending over flexor ventralis in adult males (vs. posteriormost section of these muscles reduced, nearly absent, and not laterally extending over flexor ventralis, except in G. major ) and by not having the distal portion of the fourth ventral procurrent ray of caudal fin in adult males flattened in sagittal plane (vs. distal portion strongly flattened sagittally, except in G. m a j o r and G. valencia ). The species is also distinguished from most congeners by the position and extent of the caudal peduncle blotch which is more concentrated on the middle caudal-fin rays than on caudal peduncle, reaching the midlength of those rays (vs. caudal peduncle blotch situated more on caudal peduncle than on middle caudal-fin rays, not reaching midlength of these rays, except in G. sinuensis and G. m a r t a e) and the dorsal margin of the pouch scale in adult males located on the caudal-fin ray 12 or ventral to it (vs. dorsal margin of pouch scale located dorsal to this ray, except in G. atracaudatus and G. venezuelae ). The possession of a lobe on the posteroventral margin of the pouch scale in adult males differentiates Gephyrocharax chocoensis from G. atracaudatus , G. intermedius , and G. major . Additionally, Gephyrocharax chocoensis is distinguished from G. major by the absence of accessory scales on the pouch scale of adult males (vs. presence of these scales) and by having the second and third ventral procurrent rays strongly curved dorsally and ventrally in adult males (vs. second and third rays straight). It can be distinguished from G. melanocheir , G. t o r re s i, and G. valencia by the possession of a terminal lateral-line tube between caudal-fin rays 10 and 11 (vs. absence of this tube). Gephyrocharax chocoensis differs from G. caucanus , G. sinuensis , and G. valencia by not presenting dark pigmentation around pelvic-fin origin in adult males (vs. presence of this pigmentation) and from G. martae by the snout to pectoral-fin length (24.5–28.6 % SL vs. 20.7 % SL).

Sexual dimorphism. Males with bony hooks on anal-, caudal-, and pelvic-fin rays. Caudal fin with short, slender, anterodorsally oriented hooks, especially on branched portions of rays 14–18 ( Fig. 11 View FIGURE 11 C). Pelvic-fin rays (rarely first ray without hooks) with short, slender, anteroventrally oriented hooks, more numerous on branched portion of rays; hooks usually paired or one per segment (few and unpaired on bases of rays). Anal fin with slender, anterodorsally or anterolaterally placed hooks with broad bases; from 3 to 24 pairs per ray located from posteriormost unbranched ray and up to ten anterior branched rays, larger hooks on middle rays of this range (one male with pair of minute hooks on posteriormost ray). In adult males, usually middle anal-fin rays slightly longer than remaining rays, resulting in convex-shaped anal-fin margin. In females, anal-fin rays gradually decreasing in length from anteriormost branched ray to posteriormost branched ray; anal-fin margin somewhat concave or straight. Anal-fin base of adult males slightly concave or curved along its midlength, this base straight in females. Adult females without externally developed urogenital papillae.

Males with anal and dorsal fins reddish in life; these fins yellowish and grayish in females. Mature males with hypertrophied scale forming pouch on lower caudal-fin lobe and with ventral procurrent rays 2 and 3 forming spurshaped structure. Scarce small aggregations of apparent glandular tissue located on caudal-fin rays and medially to pouch scale. First ventral procurrent ray with moderate or strong concavity on its ventral margin ( Fig. 11 View FIGURE 11 c). Second ventral procurrent ray somewhat longer than third ray, reaching distally two thirds of first ventral procurrent ray, and flattened in sagittal plane (especially on its distal portion). Posterior portion of third ventral procurrent ray weakly developed laterally. Pouch scale with 22–39 radii, usually located between caudal-fin ray 16 and third ventral procurrent ray. Posteroventral pouch-scale lobe well developed, extending along third ventral procurrent ray ( Figs. 11 View FIGURE 11 C–D). Dorsal margin of pouch scale attached via soft tissue (apparently connective) to caudal-fin rays 11 or 12 to 14. Posterior margin of pouch scale located between caudal-fin ray 14 or 15 and third ventral procurrent ray. Four scales in vertical series situated ventral to terminal lateral-line scale, overlaying posterior portion of pouch scale. Dorsal margin of pouch scale usually with small notch. Females with large scale with 19 (1), 21 (1), 21 (1), 23 (1), 24 (1), 26 (1), 29 (2), or 34 (1) radii on lower caudal-fin lobe.

Mature males with gill gland, formed by fusion of 2 (1), 7 (3), 8 (4), 9 (3), 10 (8), 11 (7), or 12 (4) anterior gill filaments of ventral limb of first gill arch. Total number of ventral limb gill filaments 21 (1), 22 (1), 23 (1), 24 (1), 25 (3), 26 (5), 27 (5), 28 (6), 29 (4), 30 (1), or 31 (2). Gill-gland length 2.5–4.0 % SL (mean = 3.2 % SL). Regression comparisons of morphometric data by sex with more pronounced differences in pectoral fin to pelvic fin length (higher values in females than in males), larger specimens separating on SL axis ( Fig. 12 View FIGURE 12 ).

Distribution. Gephyrocharax chocoensis is distributed in numerous drainages of the Atrato, León, and San Juan rivers basins in Colombia ( Fig. 1 View FIGURE 1 ).

Remarks. Eigenmann (1912) stated that the holotype of G. chocoensis was collected in Istmina (Chocó region), but he did not provide the precise river or creek where the fish was captured. According to the expedition itinerary provided by Eigenmann (1912: 7–8), he collected fishes in Istmina at night (within the limits of the San Juan River basin) and then he travelled northward arriving at Tambo (within the limits of the Atrato River basin). From these observations, it is possible to infer that the holotype could be collected in some drainage within the San Juan River basin or more probably in this river itself, since Istmina is located near the river. However, the precise drainage cannot be ascertained on the basis of this information.

Gephyrocharax chocoensis has a geographic variation in the presence/absence of humeral blotch, which is unique in the genus. The populations of the Atrato and León rivers basins possess a humeral blotch (although not intensely pigmented), whereas the populations of the San Juan River basin (e. g. holotype) lack this blotch. This difference between the populations is herein considered intrapopulational variation due to the fact that the presence/absence of the humeral blotch does not seem to be a sufficient reason for distinguishing two populations as distinct species. In the SPCA of the morphometric data, the populations were not differentiated along its components ( Fig. 13 View FIGURE 13 ). Additionally, the meristic, osteological, and myological data of both populations greatly overlap, which again reveal little evidence for the recognition of more than one species.
