Diagnosis. A species of Trachinotus in which adults have 3–5 silvery gray (in fresh specimens) oval or vertically oblong spots above or slightly touching lateral line (spots usually absent in specimens <15 cm FL); only the first spot positioned above the pectoral fin and several of the larger spots much larger than eye diameter; dorsal fin VI- or VII-I, 22–24; anal-fin II-I, 19–22, rarely 22; vomerine tooth patch round or triangular-shaped and palatine tooth patch relatively short ( Fig. 2A View TABLE 2 , Table 2 View TABLE 2 ). Selected mensural data mostly for specimens> 200 mm FL are given in Table 8 View TABLE 8 and selected measurements are plotted in Figs. 6–8 View FIGURE 6 View FIGURE 7 View FIGURE 8 .

Comparisons. Trachinotus botla is superficially similar to the allopatric T. coppingeri but adults differ in having one large spot above the pectoral fin (vs. two spots above lateral line); segmented anal-fin rays 19–22, rarely 22 (vs. 22–24 rays); vomerine tooth patch round or oval-shaped (vs. vomerine tooth patch frequently chevron-shaped, Table 2 View TABLE 2 ); and ratio of pelvic-fin length to pectoral-fin length greater than in the three other species ( Fig. 8 View FIGURE 8 ). Adults of Trachinotus botla differ most noticeably from both T. baillonii and T. macrospilus in having much larger spots on the sides, the largest about equal to or larger than eye diameter (vs. smaller than or only a little larger than iris diameter), and in fresh specimens the spots are silvery gray (vs. black).

Size. Largest specimen examined 56 cm FL, 75 cm TL. The Australian Anglers Association (WA Division) reported a maximum weight of 3.5 kg for Trachinotus botla based on a fish from Quabbo, Western Australia, caught in August 1983.

Ecology and life-history. In a study of the biology and life history of Trachinotus botla in South Africa, Parker and Booth (2015:251) stated “it appears to be the only ‘permanent’ surf zone carangid species that completes its entire life cycle inshore.” Based on age determinations from otoliths, these investigators determined that Trachinotus botla is a fast-growing and short-lived species. Fish attained 132 mm FL within two months and the oldest male and female were both six years old and measured 434- and 495-mm FL respectively. Age at 50% sexual maturity was calculated as 247 mm FL. Spawning season was between November and February. Small fish were restricted to shallow areas of the inshore surf zone and fed predominantly on copepods, small teleosts, and mole crabs. Larger fish fed on mussels, gastropods, and crab megalopae in deeper areas of the surf zone. In South Africa 45% of Trachinotus botla 10–35 cm FL had a large parasitic isopod, Cymothoa borbonica Schioedte and Meinert , attached to the tongue ( Parker and Booth, 2013). Although the isopod restricts the mouth cavity, damages the basihyal (tongue), and causes a decrease in growth rates, parasitized fish seem to feed effectively.

Distribution. ( Fig. 13 View FIGURE 13 ) South Africa (Algoa Bay), to Somalia, Madagascar, Gulf of Oman to Pakistan, India, Sri Lanka and Myanmar, and south to Indonesia (West Java, Pelabuhanratu) and Western Australia. All records of T. botla from Papua New Guinea and New Britain ( Munro, 1956, 1967) apparently are based on misidentifications of T. baillonii ; however, Munro’s (1967, pl. 26, fig. 393) drawing of Trachinotus russelli appears to be a slight modification of previously published ones of T. coppingeri based on New South Wales specimens. The four “Fairwind” specimens available from New Britain ( CSIRO C176, Jacquinot Bay and C1053, Pulie) and Papua New Guinea ( CSIRO C241, Woodlark Island) and ( CSIRO C868, Daugo Island) collected during 1948 and 1950 are all T. baillonii .

Etymology. The specific epithet botla is based on the common name used by native people in India for fishes during the early 1800s.

Nomenclatural history. Shaw’s (1803) Scomber botla , a composite species, was based primarily on Russell’s (1803) plate 142 of “botla parah” from Vizagapatam, India, here reproduced as Fig. 14 View FIGURE 14 . When an original description relates to more than one taxon the availability of a name is not affected (Article 17 of the International Code of Zoological Nomenclature, ICZN 1999). In his brief original description Shaw referred to two of Russell’s plates, with plate 142 clearly referable to Trachinotus botla and plate 137 to the carangid now known as Scomberoides commersonnianus Lacepède. In contrast to plate 142, Shaw preceded his reference to plate 137 by a question mark indicating uncertainty about their conspecificity although his text description included characters of both genera. In the original description of Trachinotus russelii (misspelling of Russell), Cuvier in Cuvier and Valenciennes (1832:436) did not mention Shaw’s earlier description (perhaps unaware of it) but cited Russell’s plate 142 indicating that it was a drawing of his new species, hence adoption of the patronym. Day (1875) also recognized T. russelii as a senior synonym, as did Weber and de Beaufort (1931:289). In a footnote the latter authors specifically rejected Shaw’s name based on the composite nature of the description; other authors followed that opinion or unquestionably adopted Cuvier’s name. In contrast, Ogilby (1915:95) concluded that Shaw’s name has priority over T. russelii Cuvier because both descriptions were based on the same Russell figure. All Australian ichthyologists have followed Ogilby in recognizing Trachinotus botla as a senior synonym of T. russelii and since the 1980s most authors who published on Indo-West Pacific Trachinotus have done likewise (see synonymy).

According to Fricke et al. (2019) no types of T. botla are known. In view of the above nomenclatural inconsistency and following qualifying conditions of Article 75.3 of the Code ( ICZN, 1999), we designate CAS-SU 14445 as the neotype ( Fig. 15 View FIGURE 15 ) of Scomber botla Shaw. This 342 mm FL (316 mm SL) specimen was obtained from Vizagapatam, India, by A.W. Herre in 1940 (no exact date). The specimen has dorsal fin VII-I, 22, anal fin II-I, 20, developed gill rakers 6+12, and vomerine and palatine tooth pattern type A. The two largest body spots on the left side are 33.6 and 30.2 mm in height and the eye diameter is 18.0 mm. The following measurements are given as percent FL: dorsal-fin lobe height 41.5, anal-fin lobe height 44.5, pectoral-fin length 16.7, and pelvic-fin length 10.0; ratio pectoral/pelvic = 1.7.
