+
+ + +Remarks + + +Koeda & Teramura (2019) +re-described + +T. pacificus + +based on +two specimens +( +96.2–122.5 mm +SL) from the Pacific Ocean, noting that in the Indian Ocean, the species was previously recorded only from early juveniles ( +9–21 mm +SL) (see also +Anderson 2022 +). An exception to this was the record of +nine adult +specimens ( +140–204 mm +SL) reported by +Parin & Piotrovsky (2004) +, who provided some meristic and morphometric data; however, no detailed descriptions were given, or voucher specimens preserved. Therefore, the specimens analyzed in this study represent the largest + +T. pacificus + +individuals examined in detail with vouchers deposited in a scientific institution. Morphological data obtained from the +Sri +Lankan specimens align with most morphological characters of + +T. pacificus + +, including the +holotype +. The few morphological discrepancies, such as preorbital depth and first anal-fin spine length ( +Table 1 +), may be attributed to ontogenetic growth, intraspecific variation, body distortion or shrinking caused by preservation, and/or slight differences in measuring methodologies. Our study confirms most of the meristic characters previously reported to distinguish + +T. pacificus + +from its congeners. These characters include 75 (72–80) longitudinal scale rows along body axis (vs. +83–95 in + +T. atlanticus + +and +97–114 in + +T. cuvieri + +); 39 (39–43) vertebrae (vs. +44–51 in + +T. atlanticus + +and +52–58 in + +T. cuvieri + +); 11 or 12 (9–12) first dorsal-fin spines (vs. +13–17 in + +T. atlanticus + +and +15–21 in + +T. cuvieri + +) and extends the known upper and lower ranges for other characters: 12 (6–9) gill rakers on upper limb (vs. +5–8 in +both + +T. cuvieri + +and + +T. atlanticus + +) and 9 or 10 (12–16) gill rakers on lower limb (vs. +9–14 in + +T. cuvieri + +and +10–14 in + +T. atlanticus + +). The new data obtained from the three +Sri +Lankan specimens also variously extend the upper ranges of some body ratios in + +T. pacificus + +such as head length, body width, snout length, pectoral fin length, caudal peduncle length, dorsal and anal-fin spines length ( +Table 1 +). Furthermore, morphological analyses herein ( +Sri +Lankan specimens + literature data) provide new characters that may be useful to distinguish + +T. pacificus + +from + +T. cuvieri + +: head length (25.3–28.7% SL vs. 18–25% SL); orbit diameter (6.0–9.6% SL vs 2.7–4.5% SL or 26.2–28.7 vs. 14.1–26.0% HL). + + +Notably, the head length, body depth and pectoral-fin ratios for the +holotype +of + +T. pacificus + +provided by +Anderson (2022) +, are not congruent with the values provided by the original description ( +Abe, 1953 +) (see +Table 1 +). It is also interesting to note that the +Sri +Lankan specimens of + +T. pacificus + +appear to have a darker fresh coloration relative to the Taiwanese specimen figured in +Koeda & Teramura (2019) +. + + +Genetics +. Pairwise sequence divergence based on the COI gene region for + +T. pacificus + +was comparatively high with + +T. atlanticus + +(14.3%) and + +T. cuvieri + +(8.6%). Further, there was a clear genetic divergence between + +T. cuvieri + +and + +T. atlanticus + +(pairwise K2P, 8.8%) ( +Table 2 +). The Maximum Likelihood phylogenetic tree, inferred from the mitochondrial COI nucleotide sequences supports two distinct lineages of + +Tetragonurus +. + +One lineage contains two sister species namely + +T. cuvieri + +and + +T. pacificus + +, while the other lineage has a single species + +T. atlanticus + +( +Fig. 5 +). The Sri Lankan sample ( +2023.09.01 +NH) clustered with a sequence of + +T. pacificus + +( +Japan +) published in + +Teramura +et al +. (2022) + +with a pairwise distance of 0.04%. + +Tetragonurus cuvieri + +has an intraspecies pairwise distance of 1.3%. This intraspecies variation within + +T. cuvieri + +could be explained by its wide distribution as well as larger number of available sequences for the species. Whereas + +T. atlanticus + +has an intraspecies variation of 0.63% pairwise distance. + + +
