Senior Synonym

Twelve species from the Bay of Bengal, the Red Sea, the western Indian Ocean, and southwestern Australia are reclassified in Marmorofusus. These include: Murex undulatus Gmelin, 1791, a senior synonym of Murex variegatus Perry, 1811 and Fusus laticostatus Deshayes, 1831, formerly regarded as a junior synonym of Marmorofusus nicobaricus (Röding, 1798); Murex verrucosus Gmelin, 1791 (synonyms Fusus tuberculatus Anton, 1839 non Lamarck, 1822, F. marmoratus Philippi, 1846 and F. rudicostatus G.B. Sowerby II, 1880); F. polygonoides Lamarck, 1822 (synonym F. biangulatus Deshayes, 1833); F. tuberculatus (Lamarck, 1822) (synonyms Fusus indicus Anton, 1839, F. maculiferus Tapparone Canefri, 1875, Fusinus t. priscai Bozzetti, 2013 and F. t. fuscobandatus Bozzetti, 2017); Fusus philippii Jonas in Philippi, 1846, an earlier name for Fusus tessellatus G.B. Sowerby II, 1880 (other probable synonyms Fusus exilis Menke, 1843, non Conrad, 1832 and Fusinus dampieri Finlay, 1930, replacement name for F. exilis Menke); Fusus oblitus (Reeve, 1847) (synonym Fusus turrispictus Hedley, 1918); F. leptorhynchus Tapparone Canefri, 1875 (synonym F. subquadratus G.B. Sowerby II, 1880), Fusinus vercoi Snyder, 2004; F. wellsi Snyder, 2004; F. brianoi Bozzetti, 2006; F. verbinneni Snyder, 2006; and F. bishopi Petuch & Berschauer, 2017. Fusus toreuma Deshayes, 1843, sometimes misidentified as M. tuberculatus, is a member of the Fusinus colus (Linnaeus, 1758) species group.

The Relationship

This chapter reviews the evidence, nature, and development of maritime contacts in the Red Sea and from the Red Sea into the western Indian Ocean from the Neolithic until the start of the Islamic period, c. 4000 BCE–700 CE. In addition to summarizing and highlighting recent archaeological research and ongoing scholarly debates, emphasis is placed on identifying and explaining periods of intensified as well as reduced interaction, and on the relationship between internal Red Sea dynamics and contacts with the Mediterranean and the Indian Ocean worlds in light of climate, natural environment, hinterland interest, and a changing geopolitical situation.

Colour Patterns

The Doublebar Seabream, Acanthopagrus bifasciatus (Forsskål 1775) with two conspicuous vertical black bars across the head has long been recognized as a distinctive species from the Red Sea and Western Indian Ocean. Two distinct colour patterns are associated with two allopatric populations except southern Oman and Somalia which appears to be a zone of overlap: a northern population (Red Sea, through Persian Gulf, to Pakistan) with dorsal and caudal fins immaculate yellow; and a southern population (east coast of Africa from the Horn of Africa to South Africa, Madagascar, and Mascarene Islands) having the dorsal fin with a wide black margin and caudal fin rear margin with a narrow black edge (and both black margins disappearing with growth in specimens over 30 cm SL). Both populations resulted in the two valid species: A. bifasciatus for the northern population and A. catenula (Lacepède 1801) for the southern population. Nominal species (junior synonyms) of the two species are discussed.

Biogeographic Provinces

Population genetic analysis is an important tool for estimating the degree of evolutionary connectivity in marine organisms. Here, we investigate the population structure of the three-spot damselfish Dascyllus trimaculatus in the Red Sea, Arabian Sea and Western Indian Ocean, using 1174 single nucleotide polymorphisms (SNPs). Neutral loci revealed a signature of weak genetic differentiation between the Northwestern (Red Sea and Arabian Sea) and Western Indian Ocean biogeographic provinces. Loci potentially under selection (outlier loci) revealed a similar pattern but with a much stronger signal of genetic structure between regions. The Oman population appears to be genetically distinct from all other populations included in the analysis. While we could not clearly identify the mechanisms driving these patterns (isolation, adaptation or both), the datasets indicate that population-level divergences are largely concordant with biogeographic boundaries based on species composition. Our data can be used along with genetic connectivity of other species to identify the common genetic breaks that need to be considered for the conservation of biodiversity and evolutionary processes in the poorly studied Western Indian Ocean region.

Type Specimens

The Red Sea has five species of the apogonid genus Fowleria, including F. isostigma, a Pacific Ocean species not yet known from the western Indian Ocean proper. Previously, F. isostigma was placed in the synonymy of F. punctulata (Rüppell 1838). However, the taxonomic status of the latter has not been established and in previous works it was placed in the synonymy of F. aurita or F. variegata. This paper compares Red Sea specimens identified as F. isostigma with F. variegata and with the type specimens of F. punctulata. The presence of F. isostigma in the Red Sea is established and F. punctulata is confirmed as a junior synonym of F. variegata. The holotype of F. punctulata is identified by the size given in the original description. A key to the Red Sea species of Fowleria is provided.

Pacific Species

Four new species of Thysanophrys are described from the Western Indian Ocean (WIO). T. rarita, known from a single specimen taken off Somalia, is provisionally placed in Thysanophrys and is distinguished by its color pattern and number of preocular and suborbital spines. T. tricaudata is described from three specimens taken at SCUBA stations off southwestern Sri Lanka. They differ from other western Indian Ocean (WIO) Thysanophrys in color pattern, lack of ocular flaps, number of dorsal fin spines and scale counts.  The remaining two new species are somewhat similar to the widespread Indo-Pacific species, T. chiltonae Schultz (1966). T. randalli is described from specimens taken at the Amirante Islands and Mauritius. It may also be widespread in the Indo-Pacific, but differs from T. chiltonae in nasal spine structure, color pattern, type of iris lappet margin, and in having a much shorter maximum size. T. springeri also appears to be a smaller species than T. chiltonae and, aside from one record off Djibouti, is restricted to Red Sea. It also differs from T. chiltonae in color pattern, in having fewer pectoral rays and fewer scale rows between the second dorsal-fin insertion and the lateral line. Although T. chiltonae is relatively common in the northern Indian Ocean, it does not appear to have entered the Red Sea.

Two Populations

The cardinalfishes Archamia bilineata and A. pallida were originally described from a small number of specimens collected in the Gulf of Aqaba, Red Sea and Oman, respectively. Both species are re-described using specimens collected recently in Yemen and Kenya, including the first known adult of A. pallida. These new collections increased the geographical range of both species considerably. Differences between the two populations now known for each of the species are discussed.

AbstractDespite his familiarity with the well established Indo-Persian history‐writing traditions, ‘Abdullāh Muḥammad al-Makkī al-Āṣafī al-Ulughkhānī ‘Ḥājjī al-Dabīr’ (b. 1540) chose to write his history of the Gujarat Sultanate and of other Indo-Muslim polities in Arabic. Ulughkhānī consulted several Persian chronicles produced in Delhi and Ahmedabad, including Sikandar Manjhū’s Mir’āt-i Sikandarī (composed c. 1611) that has served as the standard history of the Gujarat Sultanate for modern historians. Despite its ‘exceptionalism’, Ulughkhānī’s early seventeenth-century Ẓafar al-wālih bi Muẓaffar wa ālihi has largely been seen as a corroborative text to Persian tawārīkh. This article re-evaluates the importance of Ulughkhānī’s Arabic history of Gujarat by situating the text and its author in the social, political and intellectual context of the sixteenth-century western Indian ocean. Specifically, it demonstrates how the several historical digressions in the text are not dispensable aberrations to his narrative but integral to Ulughkhānī’s expansive social horizons at the time of robust commercial, pilgrimage, diplomatic and scholarly connections between Gujarat and the Red Sea regions.
