LL. 65–71, V. 38–39.</p><p>Males greyish brown with metallic sheen, straight pale bars, and conspicuous rows of large dorsal-fin spots; females ivory with distinct Y-shaped or curved bars and transparent paired and caudal fins with striped rows.</p><p>Description</p><p>Body proportions as shown in Table 1, meristic counts of holotype marked with asterisk. Body depressed anteriorly, deepest at dorsal fin origin; cross section merely oblate to elliptical; anterior end tapered, snout gently sloped anterior to eye. Body stout, depth of caudal peduncle greater than length. Head width greater than head depth; nostrils with short flap; gill opening slit-like, located below lateral line with lower edge not extending to ventral side of head; numerous large cone-shaped nuptial tubercles located upon snout and below eye in male individuals. Mouth inferior; rostral lobe covering 1/3 of upper lip, with 4 short barbels interspaced between, forming 3 major portions with pedal-like edges. Upper lip with papillose or granular surface. Lower lip possesses a pad with cutaneous ridges lined upon (Fig. 2), median posterior edge with a notch and two pointy protrusions; 1 st lower lip ridge lined along the posterior edge of the lower lip pad, interrupted medially; 2 nd ridge interrupted near mouth corner at both ends while forming an arch medially, with a blunt median hump; 3 rd ridge lies anterior to the arch of 2 nd ridge, not fusing with the 2 nd ridge hump. Centre of the lower lip pad with short, extra proliferated ridges which varies in position, numbers and length. Both mouth corners with one short barble (Fig. 2).</p><p>Fins. D. iii, 7*; A. ii, 5*; P1. i, 17*(4)–18(3); P2. i, 9*. Dorsal fin without any inflexible spines; lateral profile convexed; fin origin anterior to pelvic fin origin. P1 length greater than head length; fin origin anterior to gill opening, posterior end exceeds pelvic fin origin and reaches to the vertical position of 2 nd or 3 rd branched dorsal ray. Axillary pelvic lobe present; both P2 unfused, with its posterior tip just reaching anus. Anal fin with a convex posterior margin. Caudal fin obliquely truncate; lower lobe slightly longer than the upper one. Numerous minute nuptial tubercles can be seen lined along fin rays in male individuals, with tubercles on dorsal, pectoral, and pelvic fins largest.</p><p>Scales. LL. 65(1), 67(1), 68*(2), 69(1), 70(1), 71(1). Scales all cycloid, size uniform throughout body. Lateral line with pored scales, extends anteriorly until pectoral fin base. Head, pectoral fin base and the ventral side of body naked.</p><p>Axial osteology. Vertebrae 38*(4)–39(3) (Fig. 3).</p><p>Colouration while fresh. (Fig. 4-5)</p><p>In life, body overall in a greyish shade and head appears to be greenish. In fresh postmortem specimens, body greyish brown with a metallic shade in males, while in females and juveniles the body color is rather ivory. Midbody marked with a series of transverse white stripes, in males the stripes tend to be fainter in the anterior portion of body and always vertically straight, in females and juveniles the bars are always distinct and sometimes become Y-shaped or curvy. Head uniformly dusky in males, dark brownish with reticulated patterns in females. For dorsal fin, male with a broad margin and rather large spots lined in 4–5 rows, while in females and juveniles there are no distinctly coloured margin and with 3–4 rows of moderately sized spots. For P1 and P2, is male uniformly dusky with darker spotted stripes, female and juveniles transparent with 4–5 spotted rows, and pectoral fin base only dark brownish with white reticulated patterns in female and juveniles. Anal fin uniformly dusky with a dark posterior margin in male, while in females and juveniles there are no significant colourations. Caudal fin dusky with fainted rows of spots in males, in females and juveniles it’s transparent and with 5 rows of stripes.</p><p>Colouration in preservatives. In alcohol preservation, all colourations or shade faded to greyish black, all metallic colours faded.</p><p>Etymology</p><p>The specific name, putienensis, refers to Putien PrefCity of Fujian Province, PRC, where is the type locality of the new species.</p><p>Distribution and habitat</p><p>Pseudogastromyzon putienensis sp. nov. has so far only known from its type locality.</p><p>Remarks</p><p>Compared to other Pseudogastromyzon species, the morphology of the 2 nd lower lip dermal ridge can be employed to differentiate it from its congeners including P. myersi (2 nd ridge exceeding the 4 th ridge vs. not exceeding), P. laticeps (2 nd ridge unimodal vs. bimodal) and P. cheni (body with numerous stripes vs. with circular spots).</p><p>Pseudogastromyzon putienensis sp. nov. is most similar with P. fasciatus including dorsal fin elements (both iii, 7), anal fin elements (both ii, 5), overlapping lateral line scale counts (65–71, modally 68 vs. 67–80) and the patterns of numerous vertical stripes along body (9–10 stripes vs. 10–19 stripes). However, P. putienensis can be differentiated from the latter by having a metallic greenish body colour (vs. gradient from pale yellow to deep brown) and greyish fin coloration (vs. translucent or semi-transparent white).</p></div>	https://treatment.plazi.org/id/78317242FFEA142F63B4923DFFCBF9CC	Public Domain	No known copyright restrictions apply.
