Short Description
Diagnosis after Notarbartolo di Sciara et al. 2019 [27727]: A small mobulid with very short pectoral fins and with one of the lowest aspect ratios of the genus (i.e. the ratio of DW to disc length, 1 : 0.578, n = 50), with high relative values of longitudinal metrics (e.g. disc length and anterior projection; see also Figure 29A in Notarbartolo di Sciara, 1987). Head and cephalic fins very elongated: tip of cephalic fin to spiracle 16.5% of DW (n = 50); pre-oral length 5.9% of DW (n = 50) (see also Figures 30B and 32A in Notarbartolo di Sciara, 1987). No caudal spine. Base of tail quadrangular in section. Spiracle very small, subcircular, ventral to plane of pectoral fins. Distinctive dark blotch on ventral side of pectoral fins at the midpoint along the leading edge. Branchial filter plates distinctively reduced, with four (rarely five) lateral lobes; terminal lobe also distinctively elongated, leaf shaped; colour of plates whitish pink. Tooth bands on average 73% of mouth width. Most teeth in adult males examined here with multiple long lingual cusps.

Distribution
Mobula eregoodoo has a wide range, encompassing the tropical– subtropical Indian and Western Pacific oceans (Figure 8; Table 2) from the northern Red Sea (26 N; Egypt) to South Africa (29 S; Durban; S.P. Winter, pers. comm.), and eastward into the Arabian–Persian Gulf, Arabian Sea, Pakistan, Southern India, Bangladesh, Malaysia, West and North Australia, and into the Indo-Pacific region, including Sarawak and parts of Indonesia. Its range also extends into the tropical West Pacific, including Taiwan (22 N; Kaohsiung), western Papua New Guinea, and eastern Australia (26 S; New South Wales) (Broadhurst et al., 2018; Couturier et al., 2012; Notarbartolo di Sciara et al., 2017; Stevens et al., 2018) (Notarbartolo di Sciara et al. 2019 [27727]) Source: www.gbif.org
