Colour. Freshly collected fish. (Figure 9). Head and body ventrally white and ventro-laterally white or palegrey whitish with numerous red, brown or dark-grey dots of half pupil size or less, placed mostly on individual scales (Figure 9 A, B, E, F); in all six specimens shown in Figure 9 (least in holotype, Figure 9 A), red blotches of different form and size or larger red pigmentation patches below or behind eye on gill cover and/or on body ventrally or ventro-laterally either covering larger areas (Figure 9 B, C) or more restricted to smaller areas on or behind belly (Figure 9 E, F); some of these blotches and patches may have catch/treatment-related context; head from above snout and eye and body above lateral line red-brown or dark-grey mottled, bordered below by a mid-lateral stripe of pupil width which runs rather straight or only slightly bent from caudal-fin base to eye in yellow, beige, pale red or pale brown colour and continues from eyes (with red or pale-red iris) to snout either in similar colour and intensity (Figure 9 B–D), or slightly darker, but weaker (Figure 9 E, F), or rather faint and indistinct (Figure 9 A); on the mid-lateral body stripe from behind head to behind second-dorsal fin up to 4 sections with 1–3 red, brown or black dots of less than pupil width; behind head until below base of second dorsal fin in adults, a thin white or pale creamy stripe separates the dorsal body pigmentation from the mid-lateral body stripe (Figure 9 A, B, E); lateral line visible especially in subadult (Figure 9 C) and small adult (Figure 9 F) as a series of mostly red, dark-grey or black dots placed well above mid-lateral stripe in anterior half of body, then starting to cross the stripe just anterior of second dorsal-fin base, continuing behind dorsal fin just below stripe towards caudal-fin base; barbels entirely yellow; caudal fin with 9–13 red, dark brown or black oblique bars crossing mostly both lobes entirely, if not placed on fin base or fin tips; upper lobe covered by 4–6 (3–4 in subadults) red, red brown, or dark brown bars of pupil or slightly narrower width, the distal-most bar sometimes covering fin tip (Figure 9 A, F); bars separated by hyaline interspaces of similar width or slightly wider; in large adult (Figure 9 E) dark-brown blotches on three intermediate bars; lower caudal-fin lobe covered by 5–7 (3–5 in subadults) red, red brown or dark brown bars and hyaline interspaces of similar width or slightly narrower than on upper fin lobe in adults, whereas more variable in subadults; in four specimens (Figure 9 A–D), the lower caudal-fin lobe ends in a black tip; a red or brown stripe stretches entirely or only dorsally along the lower caudal-fin lobe covering partly the bars in both aduts and subadults; first dorsal fin almost entirely covered with pale-red, beige or pale-brown pigmentation; second dorsal fin with 3 red stripes of orbit width or less, one stripe at or close to fin base, one at or close to fin tip, the latter and in some fish also the middle stripe slightly darker; pelvic fins hyaline with up to 5 narrow red or brown stripes; anal fin with 1–3 red or brown stripes and hyaline or whitish interspaces; pectoral fins hyaline.
Live fish in situ. Active fish. (Figure 10 A–D). Head and body ventrally white, with numerous tiny red or beige dots associated with 4 scale rows and, in three of four fish, with additional, larger rounded and partly connected red blotches, ca. 25 of the latter visible in fish from the type locality which was kept in a tank (Figure10 A); fewer and more ventrally positioned blotches in two fish photographed in situ in Central Philippines (Figure 10 C, D); head from above snout and eye and body above lateral line pale-grey or rose mottled, bordered below by a mid-lateral stripe in red colour (that appears brown when photographed without flash, see Figure 10 B) of pupil width which runs rather straight from caudal-fin base to eye, continuing through eyes (with iris red-coloured in stripe shape) and then bending ventrally towards snout tip, becoming slightly narrower and weaker; 5 well separated, rectangular dark-red sections on mid-lateral body stripe (not well visible in Figure 10 B), one shorter behind gill cover, two longer ones below dorsal fins, one shorter behind second dorsal fin, and one less conspicuous, rather short section close to caudal-fin base; each section except for the posterior-most with a horizontal series of 2–4 black dots of a little less than pupil diameter; the dotted section behind the second dorsal fin connecting closely to red saddle in tank fish (Figure 10A), the latter reaching from dorsal body margin behind second dorsal fin to stripe in V-form; lateral line, as also observed in freshly collected fish, proceeds parallel above mid-lateral body stripe during first half of body, then crossing and continuing just below stripe to caudal-fin base; lateral line marked by several small red, beige or grey dots that become more conspicuous in positions of dots on mid-lateral body stripe below; barbels entirely yellow; caudal fin with 8–12 red-brown oblique bars which appear dark-brown in the small possibly adult specimen photographed at distance without flash (Figure 10 B); dorsal fin lobe crossed by 3–5 bars of pupil width, the distal-most bar covering fin tip in two specimens (Figure 10 A, D); in three specimens the bars are reduced to dark red or dark brown blotches (Figure 10 B, C, D) leaving the remaining parts of bars as pale, mostly hyaline traces (Figure 10 C, D); bars on upper lobe separated by hyaline interspaces of similar width; lower caudal-fin lobe crossed in adults by 5–7 dark red (dark brown in Figure 10 B) bars which are similarly shaped and sized as bars on upper lobe; while in the tank specimen the bars are of varying intensity but typically shaped, the bars in the other three active fish show a blotch-like concentration of intense colour in the middle of the lower lobe, leaving the ventral and dorsal areas of each bar rather inconspicuous (however still visible, e.g. Figure 10 C, D); in addition, a red stripe is formed on the lower lobe of the tank specimen that covers the lobe almost entirely (apart from ventral margin) and a pale red stripe is also weakly visible along the dorsal half of lobe in two of the three other specimens (Figure 10 C, D); the first dorsal fin (only well visible in Figure 10 A) is mostly weakly pale red, leaving the tip almost completely unpigmented hyaline; the second dorsal fin with 3-4 red to brown stripes of about pupil width or less, at least one of the distal two stripes more intensely coloured than the stripes (or single stripe) closer to fin base which appear rather pale red and partly hyaline; interspaces between stripes in part with white pigmented fin rays; pelvic and anal fins partly hyaline with weak pale grey pigmentation indicating stripes; pectoral fins hyaline, only very faintly visible.
Resting fish. (Figure 10 E, only differences from the above colour description indicated). Large areas on head and body covered with red, in particular below eye, on gill cover, above pectoral-fin base, two large red bands running from dorsal fins down to ventral margin, the anterior band rather straight from first dorsal fin, the posterior band obliqueand wider, covering also the area of and below saddle; the two bands connecting on ventral body margin with each other and covering most of ventral underside except for an inverted V-shaped pale area behind pelvicfin base and caudal peduncle; caudal peduncle mostly white with three round orbit-sized red blotches on ventral margin and one more elongated red blotch just above the last ventral-margin blotch; mid-lateral body stripe only visible in areas without red band markings and almost indistinct whitish on caudal peduncle, then orange anterior to second dorsal fin between the large red bands and behind head, turning into red on gill cover, then crossing eye (with iris red-colour in stripe shape) and bending towards snout tip, still in red colour; caudal fin with 9 oblique dark grey bars, on dorsal lobe 4 bars (including one on tip) which are dark pigmented only on dorsal margin of fin, while becoming ventrally pale grey and rather indistinct; the 5 bars on lower fin lobe entirely dark grey, slightly wider than whitish interspaces, with faint appearance of a grey stripe only close to caudal-fin base; area of red pigmentation on first dorsal fin concentrated centrally and in part of fin, leaving the tip entirely pale hyaline.
Preserved fish. Head and body mostly uniformly pale brown, pale greyish, greyish brown or brown, sometimes slightly darker dorsally, gill cover silvery or pale and partly transparent, lateral line, when intact, well visible in entire range from behind head to caudal-fin base; barbels pale brown or pale creamy; mid-lateral body stripe completely lost, but often remains of dark mid-lateral dots in the area of stripe below and posterior to dorsal fins (in 35 % of 100 adults vs. 33 % of 6 subadults); dark pigmentation remains also in other areas: saddle behind second dorsal fin (65 % vs. 67 %), caudal fin (98 % vs. 100 %) and second dorsal-fin distal stripe (92 % vs. 100 %); on caudal fin with retained pigmentation remains of up to 6 oblique bars visible on each lobe; in adults 96 % (of 101 fish) and all subadults show remains of bars on both lobes; of all adults only 2 % show no pigmentation remains (pigmentation degree 0) and 36 % have pigmentation in all body and fin regions (pigmentation degree 4); all studied subadults show pigmentation remains with pigmentation degree 4 occurring in 33 %. Unpigmented areas of caudal, second dorsal fins and other fins entirely pale and partly hyaline.
Etymology. The name refers to the variable number of 7 or 8 dorsal-fin spines in this species, which is in contrast to most other goatfish species and all other Indo-Pacific congeners which have either 7 or 8 dorsal-fin spines.
Distribution, habitat and size. W Pacific, from border to EIO in S Indonesia to Singapore, Gulf of Thailand, Vietnam, Central Philippines, South China, Taiwan, and S Japan; 6–24 m depth, sandy or muddy bottoms; maximum size 16 cm SL.
Intraspecific comparisons. To ensure that the dimorphic expression of seven and eight dorsal-fin spines in U. heterospinus n. sp. is indeed a single-species characteristic, as is unusual in goatfishes, the two morphs were compared using the entire set of studied characters. As was expected, no differences could be discovered in any single character (Table 8), nor in any combinations of characters or in statistical comparisons of morphometric, meristic and colour characters.
Subadults of U. heterospinus n. sp. differ from adults in slightly shallower body at anal-fin origin (especially when analyzing populations separately; Figure 11), fewer rudimentary gill rakers on lower limb (Figure 11; while total gill rakers do not differ among size classes), fewer oblique bars on caudal fin (Tables 2, 9), and the bars slightly wider, almost interconnected in fresh subadults (Figure 9 C) vs. narrower and more clearly separated in adults (Figure 9 A, B, D–F; Figure 10).
Among the three populations of Upeneus heterospinus n. sp. from N Vietnam, South-central Vietnam and the Gulf of Thailand no clear distinction was found in any single or combination of morphological or colour characters occurs that would support separation into different taxa. However, each population can be distinguished statistically (Table 11). For instance, the Gulf of Thailand population has a significantly higher maximum body depth than the other two populations. The N Vietnam population differs significantly from the two other populations in having a shallower body at anal-fin origin, shallower caudal peduncle, shallower maximum head and suborbital depth, shorter interorbital length, longer pectoral fins and higher second dorsal fin. The South-central Vietnam population has a significantly wider snout and longer barbels than the other two populations and differs in addition in pairwise comparisons with the northern population. As stated for U. margarethae, the considerable amount of significant differences among populations contrasts however with much greater differentiation among species, as revealed by the statistical comparisons among three of the five species (Table 4, see also section on Interspecific comparisons further below).
Regarding meristic characters, the Gulf of Thailand population has a significantly lower gill-raker count than the other two populations (Table 5). With respect to preserved colour patterns, the three populations differ significantly from each other with the South-central population showing the highest degree of dark pigmentation, followed by the N Vietnam and the Gulf of Thailand populations (Table 6). In none of the three populations, individuals that completely lack dark pigmentation remains (pigmentation degree 0) occur. When comparing the four examined pigmentation patterns individually, the only significant differences exist in the presence/absence of a saddle and mid-lateral dots (Table 7). The latter are completely lacking in the Gulf of Thailand population. Regarding fresh colour patterns, no clear population differences can be observed when comparing the available images (see also Figures 9, 10).
Remarks. Upeneus heterospinus n. sp. has been reported from many areas using various names and most recently as U. spottocaudalis from Japan (Bandai et al. 2018). From Vietnam, where it is a common species that is frequently encountered in fish markets, biological data have been recently collected and published using preliminary identification information (Emel’yanova & Pavlov 2014; Pavlov & Emel’yanova 2016).
