Gnathia maculosa sp. nov. is described from males reared in a laboratory from larvae that were collected as ectoparasites on elasmobranchs, caught off Okinawa Island in the Ryukyu Archipelago, southwestern Japan. The species is most similar to G. trimaculata but it is distinguished from G. trimaculata by deeper and narrower dorsal sulcus, a narrower body, and the wider pylopod. Gnathia trimaculata, previously recorded from Great Barrier Reef, Australia, was also collected from elasmobranchs caught off Okinawa Island. The record of G. trimaculata from Okinawa indicates a wide range of the distribution of the gnathiids inhabiting elasmobranchs.

Studies carried out over several years on a tropical estuary, the Ross River Estuary, have shown that copper speciation is influenced by both terrestrial and marine humic substances. While terrestrial humic substances are mobilized by high freshwater runoff in the monsoonal season, Trichodesmium blooms mobilize high concentrations of marine humics to the inshore zone and increase labile forms of copper. The marine humics are more soluble than the terrestrial humics and persist in coastal waters of the Great Barrier Reef lagoon for many months prior to the wet season.

Male And Female

Gnathiid larvae were collected as ectoparasites on elasmobranchs caught in fisheries off Okinawa Island, Ryukyu Archipelago, southwestern Japan. The larvae were reared in a laboratory aquarium; some metamorphosed into male and female adults of Gnathia nubila n. sp. and Gnathia grandilaris Coetzee, Smit, Grutter & Davies, 2008. Males of G. nubila n. sp. were easily distinguished from all other species by the bifit and dentate mediofrontal process of the frontal border and by a narrow pleotelson. Gnathia grandilaris was originally recorded from the Great Barrier Reef (GBR), Australia, and here we report a second find of this species from the Ryukyus. Since the first description did not include female adult of G. grandilaris, we provide the morphology of female.
