“…semilunaris sp. nov. share many pale narrow lines interrupting the second dark body band (Randall, 1995: figure 653 on p. 249; Padate et al ., 2014: figure 2k; Tea, 2015; Figure 2), such being absent in all other congeners.…”

Two new species of Roa (Chaetodontidae) are described. Roa semilunaris sp. nov., based on six specimens from the Mascarene Ridge (south‐western Indian Ocean), is most similar to Roa jayakari (Norman, 1939), distributed in the Red Sea and the northern Indian Ocean, in having scales on the upper jaw, interrupted pale lines within the second dark body band, and similar coloration and shape of the pelvic fin. However, the former is readily distinguished from R. jayakari by a wider whitish interspace between the second and third black bands [width of interspace at lateral line level 15.9%–18.5% of standard length (SL) in R. semilunaris sp. nov. (vs. 5.1%–8.5% of SL in R. jayakari)], with 9 or 10 pored lateral‐line scales in the interspace (vs. 3–5); an oval or semicircular ocellated blotch on the soft‐rayed portion of the dorsal fin (vs. a circular blotch); the head higher and longer [head length 35.0%–36.7% of SL (vs. 40.8%–44.1% of SL), head height 48.1%–50.5% of SL (vs. 52.0%–56.9% of SL)], and postorbital length 14.0%–15.1% of SL (vs. 17.0%–20.5% of SL). Roa uejoi sp. nov., based on three specimens from Guam (Mariana Islands), is most similar to Roa excelsa (Jordan, 1921) (now restricted to the Hawaiian Islands and Johnston Island), but is distinguished from the latter by having a circular dorsal‐fin ocellated spot (vs. spot distinctly oval in the latter) and a much more elongate, filamentous first pelvic‐fin soft ray, of length 119.0%–123.4% of 2nd ray (vs. not obviously filamentous, 104.9%–105.8%). A key to the eight valid species of Roa is provided.

“…The presence of myriad numbers of rare reef-associated as well as deep sea fishes suggests that structural complexities among the bottom habitats particularly coral reefs have facilitated the establishment of micro-niches that provide safe haven for diverse assemblages of demersal fishes. Moreover, the development of coastal demersal fisheries and expansion of fishing fleets has recently further enabled the discovery of many rare species (Padate et al 2014). However, excessive mechanized fishing activity in this fragile biosphere reserve has adversely affected the unique coral reef and sea-grass ecosystems (Diraviya Raj et al 2017).…”

“…The coloration of fresh specimens from India was detailed by Saravanan (2013) and Padate et al (2014: fig. 2B) (as Pa. heterura in Padate et al 2014). Although Padate et al (2014) reported two specimens (34.3-61.6 mm SL) from the Gulf of Mannar in northern India as Pa. heterura, their specimens were identical with Pa. macrura based on head appearance, including a long postorbital (relative lengths of head and snout may not be useful for identification of small specimens; see below "Species comparisons").…”

A taxonomic revision of the genus Parapterois (Scorpaenidae: Pteroinae) resulted in recognition of three valid species, Pa. heterura (Bleeker 1856) (type locality: Indonesia), Pa. macrura (Alcock 1896) (India) and Pa. nigripinnis (Gilchrist 1904) (South Africa). Previously regarded (as Pterois nigripinnis) as a junior synonym of Pterois heterurus Bleeker 1856, the lastmentioned is readily distinguishable from its congeners by having interrupted or wavy white lines and/or spots present below the eye (vs. solid white lines in congeners) and the pectoral-fin axilla with many white spots (vs. spots absent). Although Pa. macrura is most similar to Pa. heterura, the two species can be distinguished from each other by several morphometric characters, including the relative position of the orbit (with respect to the top of the nasal protuberance and the first dorsal-fin base), and the number of spinules on the cheek scales. Parapterois heterura is widely distributed in the eastern Indian and western Pacific oceans, whereas Pa. macrura and Pa. nigripinnis are restricted to the Arabian and Laccadive seas, and the southwestern Indian Ocean (east coasts of Mozambique and South Africa), respectively. Pterois jordani Regan 1905, Ebosia starksi Franz 1910, Pterois tanabensis Tanaka 1918 and Ebosia pavo Schmidt 1931, all described from Japan, are regarded as junior synonyms of Pt. heterurus. Pterois natalensis von Bonde 1923 (type locality: South Africa) is synonymized under Pt. nigripinnis. Lectotypes are designated for Pt. macrura and Pt. nigripinnis, and a key to species of Parapterois is provided.
