Lepidotrigla longipinnis Alcock, 1890 Proposed vernacular: Stellar Gurnard

( Figs 1A , 2A, B , 3A, B , 4 , Table 1)

Lepidotrigla spiloptera var. longipinnis Alcock, 1890: 429 (new variety based on specimen from Bay of Bengal); Alcock, 1899: 68 (description).

Lepidotrigla riggsi Richards & Saksena, 1977: 215 (replacement name due to incorrect perceived homonymy of longipinnis with Lepidotrigla longispinis Steindachner & Döderlein, 1887 ; diagnosis and distribution); Fischer & Bianchi, 1984: vol. V, unpaged (taxonomy, fisheries and distribution); Richards, 1992: 63 (nominal species, selected characters); Krishnan & Mishra, 1993: 220 (survey list); del Cerro & Lloris, 1997: 51 (comparison with new species).

Lepidotrigla longipinnis: Alcock & McArdle, 1900 : pl. 31; Manilo & Bogorodsky, 2003: S103 (check list); Eschmeyer, et al, 2017: accessed 4 Sep 2017 (catalogue of nominal species).

Diagnosis. Lateral profile of body with gradual convexly curved taper to caudal peduncle; distinctive postorbital notch above and behind each eye but not extending across top of head as occipital groove; rostral process with broad obtuse angle or straight when viewed from above, with prominent forward directed blade-like spine at each corner often mounted on somewhat triangular base; scales moderately adherent; lateral line with 56–61 pored scales; 13–15 oblique scale rows below lateral line; first dorsal fin with 8 or 9 spines, second with 15 or 16 rays; anal fin with 14–16 rays; pectoral fin reaching sixth to tenth anal fin ray. Caudal fin mostly red with white transverse band near base; inner surface of pectoral fin with large black oblong patch ventrally superimposed with scattered pale blue spots, remainder greenish with reddish margins dorsally, ventrally and basally.
