In preservative: head, body and fins pale; dark stripe on sides from snout to caudal fin and scattered dark spots on body and fins still distinct (Fig. 2). Distribution. Known from off the southwest coast of India in the Arabian Sea, at depths of 170–260 m, and off the island of Lombok in eastern Indonesia (Fig. 3). Etymology. The species is named in honour of John E. Randall, in recognition of his contribution to the taxonomy of tropical marine fishes and more specifically his contribution to the taxonomy of Liopropoma . Proposed vernacular name: Indian basslet. Comparisons. Liopropoma randalli is distinguished from all other described species of Liopropoma by a combination of color pattern, meristics and morphometrics. Amongst the Indo-West Pacific species of Liopropoma , L. randalli is readily distinguished from L. africanum, L. collettei Randall & Taylor, 1988, L. flavidum Randall & Taylor, 1988, L. mitratum, L. multilineatum, L. pallidum (Fowler, 1938), L. susumi and L. tonstrinum in having a continuous dorsal fin (although deeply notched) vs. a divided dorsal fin with seventh and eighth spines not joined to rest of dorsal fin by a membrane. Liopropoma randalli is distinguished from L. aurora (Jordan & Evermann, 1903) and L. latifasciatum (Tanaka, 1922) in possessing 12 vs. 13 dorsal soft rays and 8 vs. 9 anal soft rays (Randall & Taylor, 1988). Similarly, Liopropoma japonicum (Döderlein in Steindachner, 1883) is readily distinguished from L. randalli in possessing 10 vs. 8 anal-fin soft rays and 14 vs. 12 dorsal-fin soft rays (Randall & Taylor, 1988). Liopropoma maculatum (Döderlein in Steindachner, 1883) is also readily distinguished in having a much higher number of lateral-line scales (61–66) compared to the new species (46–49). Liopropoma erythraeum Randall & Taylor, 1988 and L. dorsoluteum are distinguished from L. randalli in having the anterior nostril about the same distance from the upper lip than from the posterior nostril (vs. at the front of the snout) and in having the eighth spine shorter than the sixth and seventh spines (vs. the eighth spine longer than the sixth and seventh spines) (Randall & Taylor, 1988; Kon et al. , 1999). Liopropoma incomptum Randall & Taylor, 1988 and L. aragai Randall & Taylor, 1988 can be easily separated from the new species in colour pattern with the former two species lacking any dark markings on the head, body or fins vs. a dark midlateral stripe and numerous semicircular dark spots. Similarly, L. swalesi (Fowler & Bean, 1930) also differs markedly in colour in having 6 or 7 dark stripes on the sides and a prominent dark ocellus in the soft portions of the dorsal and anal fins vs. a single dark midlateral stripe and no ocelli on the fins in L. randalli . Liopropoma randalli is similar to L. lunulatum , a widely distributed Indo-West Pacific species, which also has blackish semicircular-shaped spots on the body and sometimes on the fins. The new species differs from L. lunulatum in having a blackish midlateral stripe (vs. no dark stripes on sides), which extends from the snout (vs. a yellow stripe from the snout to the opercle and occasionally onto anterior portion of the body) to the base of the caudal fin, a shallower body (depth 3.2–3.6 vs. 2.9–3.3 in SL), and in having a shorter soft dorsal fin (longest dorsal fin ray 2.1–2.3 vs. 1.9–2.1 in head length), longest dorsal spine (third) is 3.3–3.7 (vs. 2.9–3.5 in HL in L.lunulatum ), snout length 4.1–4.3 in head length (vs. 3.5–3.8 in HL in L.lunulatum ) (Randall & Taylor, 1988; based on 8 specimens 125–187 mm SL). Although based on only small sample sizes at present, Liopropoma randalli and L. lunulatum also differ in the structure of the CO 1 gene, with specimens of L. lunulatum from French Polynesia (Moorea Biocode project) differing from L. randalli by 6.5 % (www.boldsystems.org). Liopropoma randalli is most similar to L. lemniscatum from the West Pacific, but is easily distinguished by colour pattern with the new species possessing numerous blackish semicircular spots above and below a blackish midlateral stripe vs. a dark brownish midlateral stripe and without small blackish spots on the body or fins (Fig. 4). The new species also differs from L. lemniscatum in the following characters: 1 st anal-fin spine length 10.4–12.2 vs. 8.2–8.3 in head length; 2 nd anal-fin spine length 4.4–4.9 vs. 3.8 –4.0 in head length; caudal fin length 4.1–4.4 vs. 3.7 in SL; and pelvic-fin length 5.1–5.7 vs. 4.7 –5.0 in SL. A third Liopropoma specimen collected at the Tanjung Luar fish landing site in Lombok, Indonesia, was identified as L. dorsoluteum (Fig. 5). This specimen is a new distributional record for this species, which has previously only been recorded from Japan and Taiwan (Kon et al. , 1999). : Published as part of White, William T., 2012, Liopropoma randalli, a new serranid (Teleostei: Perciformes) fish from the Indian Ocean, pp. 43-50 in Zootaxa 3439 on pages 44-49, DOI: 10.5281/zenodo.212109 : {"references": ["Randall, J.

Liopropoma randalli is distinguished from L. aurora (Jordan & Evermann, 1903) and L. latifasciatum (Tanaka, 1922) in possessing 12 vs. 13 dorsal soft rays and 8 vs. 9 anal soft rays (Randall & Taylor, 1988). Similarly, Liopropoma japonicum (Döderlein in Steindachner, 1883) is readily distinguished from L. randalli in possessing 10 vs. 8 anal-fin soft rays and 14 vs. 12 dorsal-fin soft rays (Randall & Taylor, 1988). Liopropoma maculatum (Döderlein in Steindachner, 1883) is also readily distinguished in having a much higher number of lateral-line scales (61–66) compared to the new species (46–49). Liopropoma erythraeum Randall & Taylor, 1988 and L. dorsoluteum are distinguished from L. randalli in having the anterior nostril about the same distance from the upper lip than from the posterior nostril (vs. at the front of the snout) and in having the eighth spine shorter than the sixth and seventh spines (vs. the eighth spine longer than the sixth and seventh spines) (Randall & Taylor, 1988; Kon et al. , 1999). Liopropoma incomptum Randall & Taylor, 1988 and L. aragai Randall & Taylor, 1988 can be easily separated from the new species in colour pattern with the former two species lacking any dark markings on the head, body or fins vs. a dark midlateral stripe and numerous semicircular dark spots. Similarly, L. swalesi (Fowler & Bean, 1930) also differs markedly in colour in having 6 or 7 dark stripes on the sides and a prominent dark ocellus in the soft portions of the dorsal and anal fins vs. a single dark midlateral stripe and no ocelli on the fins in L. randalli . Liopropoma randalli is similar to L. lunulatum , a widely distributed Indo-West Pacific species, which also has blackish semicircular-shaped spots on the body and sometimes on the fins. The new species differs from L. lunulatum in having a blackish midlateral stripe (vs. no dark stripes on sides), which extends from the snout (vs. a yellow stripe from the snout to the opercle and occasionally onto anterior portion of the body) to the base of the caudal fin, a shallower body (depth 3.2–3.6 vs. 2.9–3.3 in SL), and in having a shorter soft dorsal fin (longest dorsal fin ray 2.1–2.3 vs. 1.9–2.1 in head length), longest dorsal spine (third) is 3.3–3.7 (vs. 2.9–3.5 in HL in L.lunulatum ), snout length 4.1–4.3 in head length (vs. 3.5–3.8 in HL in L.lunulatum ) (Randall & Taylor, 1988; based on 8 specimens 125–187 mm SL). Although based on only small sample sizes at present, Liopropoma randalli and L. lunulatum also differ in the structure of the CO 1 gene, with specimens of L. lunulatum from French Polynesia (Moorea Biocode project) differing from L. randalli by 6.5 % (www.boldsystems.org). Liopropoma randalli is most similar to L. lemniscatum from the West Pacific, but is easily distinguished by colour pattern with the new species possessing numerous blackish semicircular spots above and below a blackish midlateral stripe vs. a dark brownish midlateral stripe and without small blackish spots on the body or fins (Fig. 4). The new species also differs from L. lemniscatum in the following characters: 1 st anal-fin spine length 10.4–12.2 vs. 8.2–8.3 in head length; 2 nd anal-fin spine length 4.4–4.9 vs. 3.8 –4.0 in head length; caudal fin length 4.1–4.4 vs. 3.7 in SL; and pelvic-fin length 5.1–5.7 vs. 4.7 –5.0 in SL. A third Liopropoma specimen collected at the Tanjung Luar fish landing site in Lombok, Indonesia, was identified as L. dorsoluteum (Fig. 5). This specimen is a new distributional record for this species, which has previously only been recorded from Japan and Taiwan (Kon et al. , 1999). : Published as part of White, William T., 2012, Liopropoma randalli, a new serranid (Teleostei: Perciformes) fish from the Indian Ocean, pp. 43-50 in Zootaxa 3439 on pages 44-49, DOI: 10.5281/zenodo.212109 : {"references": ["Randall, J.
