Pseudophallus starksi mindi: Lüling, 1974: 200 (as a geographic race of P. starksii ).

Diagnosis. Pseudophallus mindii differs from species of Pseudophallus from the Pacific coastal drainages, P. starksii and P. elcapitanensis , in having 78.9% of specimens with 13 trunk rings (vs. 14 trunk rings).

Pseudophallus mindii can be distinguished from P. brasiliensis by the following combination of characters: 13– 16 pectoral-fin rays (88.2% of specimens with 14–15), and 15–23 brood-pouch rings (93.8% adult male specimens with 15–21) vs. 12–15 pectoral-fin rays (82.4% of specimens with 13), 28–41 dorsal-fin rays (98.5% of specimens with 28–37) and 13–17 brood-pouch rings (87.7% of the adult male specimens with 14–16) in P. brasiliensis .

Pseudophallus mindii differs from P. galadrielae in having 32–42 dorsal-fin rays (96.4% of specimens with 34–42), all specimens with 7.5–10.5 subdorsal rings, 45–51 total body rings (94.4% of specimens with 46–51) vs. 27–34 dorsal-fin rays (91.6% of specimens with 27–34), 6.0–8.25 subdorsal rings (92.9% of specimens with 6.0–7.25) and 41–45 total body rings (97.1% of specimens with 41–44) in P. galadrielae .

Description. Meristic and morphometric characters detailed in table 1. General appearance in Figures 2C View FIGURE 2 and 3C View FIGURE 3 . Body without scales, covered with bony plates forming rings along its axis, bony plates horizontally oval, with an elevation in midline forming bony ridges along body. Trunk rings 12–14 (80.3% of specimens with 13). Tail rings 32–37 (90.7% of specimens with 34–35). Body rings 45–51 (85.1% of specimens with 46–48). Subdorsal rings 7.5–10.25 (93.0% of specimens with 7.75–9.75). Subdorsal trunk rings 0–0.25. Subdorsal tail rings, from 7.5–10.25 (91.0% of specimens with 7.75–9.75). Dorsal-fin origin between posterior half of posteriormost trunk ring and anteriormost caudal ring. Posterior tip of superior trunk ridge at vertical through superior tail ridge, between 7.0 and 10.0 anteriormost tail rings. Lateral trunk ridge continuous with superior tail ridge with origin on first caudal ring. Inferior trunk ridge continuous with inferior tail ridge.

Body slender and cylindrical, transversal section of trunk heptagonal, with transition to quadrangular in tail at end of superior trunk ridge. Maximum body depth of females and juveniles at middle of trunk; in males at anterior region of the brood pouch. Body depth decreasing posteriorly along superior trunk ridge to minimum depth on caudal peduncle. Dorsal profile of head straight or slightly inclined at snout region, more inclined at orbital region and straight at posterior region, with two nuchal plates between occipital region and first trunk ring. Ventral profile of head straight.

Dorsal fin not elevated, curved on first rays, straight along median portion with pointed end. Dorsal-fin rays of similar length, except the first two rays. Dorsal-fin rays 32–42 (76.7% of specimens with 35–38), posteriormost two rays closer to each other, difficult to distinguish in some specimens. Pectoral fin small, middle rays longer than outer and inner rays. Pectoral-fin origin on anteriormost trunk ring, and distal margin rarely extending beyond third trunk ring. Pectoral fin rays 13–16 (88.2% of specimens with 14 –15). Caudal fin small and fan like, with 10 rays (5 rays in each hypural plate). Pelvic and anal fins absent.

Mouth terminal, slightly inclined dorsally, jaws edentulous. Lower jaw slightly prognathous. Snout short, tubular, without dorsal or lateral ridges. Dorsal profile of snout with slight inclination following dorsal margin of eyes. Eyes located longitudinally at middle of head. Opercle occupying most of lateral surface of head posterior to eye, opercular opening reduced to pore on posterodorsal margin of opercle. Opercular ridge generally indistinct, except for some specimens with small protuberance on anterior region of opercle, following superior margin of bone. Lateral line and lateral line canals absent.

Sexual dimorphism. Males with brood pouch. Origin of brood pouch on posteriormost trunk rings, brood pouch rings extending along 15–23 body rings (93.3% of specimens with 15–21 brood pouch rings). Bony plates of the brood pouch well developed and T-shaped encasing entire lateral portion of pouch, decreasing in size posteriorly and parallel with the inferior tail ridge. Ventral region of pouch with contralateral dermal folds extending towards the midline, dividing brood pouch longitudinally. Adult females with anal papilla on anal ring with small, barely visible spicules.

Color in alcohol. Ground color of head and body usually uniform, from light beige to brown, sometimes with mottled patterns formed by different tones of brown spots. Thicker bony regions at body ridges with less or no chromatophores, forming nearly white longitudinal lines. Some specimens with series of dark arch-shaped blotches in lateral view, at every two or four rings. Bony rings with one or two white spots underneath bony plates; spots circular in shape when single spot present and oval shaped when two spots present, due to proximity of spots. Dorsolateral part of snout with layer of skin and mesethmoid forming light stripe. Dorsal-fin rays with scattered brown chromatophores. Pectoral fin hyaline. Caudal fin with same general coloration of body, sometimes in slightly different tone. ( Figs. 2C View FIGURE 2 and 3C View FIGURE 3 ).

Distribution. Freshwater Atlantic coastal drainages, from Río Cumboto, Ocumare, Venezuela, to Río Hondo, San Antonio, Belize, including freshwater drainages in the Caribbean islands ( British Virgin Islands, Puerto Rico, Jamaica and Cuba) ( Fig. 4 View FIGURE 4 ).

Remarks. The species Syngnathus mindii Meek & Hildebrand was described based on a specimen captured in a creek near Mindi, Canal Zone, Panama (USNM 81770). A tag inside the jar of the specimen has the name Siphostoma mindii , however, to our knowledge, such combination has never been used in the literature.
