Chromis tingting, a new species of damselfish from mesophotic coral ecosystems of southern Japan, with notes on C. mirationis Ta n a k a (Teleostei: Pomacentridae)
YI-KAI TEA , ANTHONY C. GILL & HIROSHI SENOU
The pomacentrid genus Chromis Cuvier (1814) is the largest genus in the family, with over a hundred species found on coral and rocky reefs throughout tropical and warm temperate seas (Allen, 1991). The genus is cosmopolitan and circumglobal, inhabiting a wide range of depths ranging from shallow coral outcrops to deep reefs below the photic zone. More extensive exploration of reef ecosystems in recent years have led to several new discoveries, particularly in species inhabiting mesophotic coral ecosystems (MCE) at depths between 40 and 150 m
(Hinderstein et al., 2010). Indeed, thirty-four species are known only from depths exceeding 50 m, and a further twelve are known from depths of 60 m or more (Pyle et al., 2008; Arango et al., 2019).
The widespread distribution of some species in the genus raises the question of whether such species are truly widespread, or whether they are actually complexes of similar species (Gill & Kemp, 2002). This may lead to the splitting of currently recognized taxa into two or more species, especially where apparent differences are noted within sympatric populations (Allen & Erdmann, 2014; Motomura et al., 2017). We herein describe a new species of Chromis inhabiting moderately deep to deep MCEs of southern Japan.
The new species is compared with related species, including the species currently called C. mirationis Tan aka (1917), with which it has been previously confused. The latter species was described briefly by Tanaka from the holotype, which is currently listed as lost. However, the specimen is extant, and we therefore provide new data on the holotype in order to justify our conclusion that it is distinct from our new species
