This study introduces four new species within the Canarium urceus complex. Canarium daveyi nov. sp. and the sympatric C. geelvinkbaaiensis nov. sp. from the region surrounding Geelvink Bay in north-eastern Indonesia, C. youngorum nov. sp. from the island of north-eastern Papua New Guinea, and finally Canarium manintveldi nov. sp from the southern South Pacific centred on Fiji and Vanuatu. These new species differ from, and are described based on, the morphology and geographical distribution from known species belonging to the C. urceus complex. This study comprises part three in a series examining the broader C. urceus complex.

A New Species

A new arhynchobatin skate, Notoraja sereti n. sp., is described based on three specimens collected from off Madang (Papua New Guinea) at depths of 800–980 m. This medium-size Notoraja skate shares with other velcro skates from the Western Pacific, N. alisae, N. fijiensis, N. inusitata and N. longiventralis, a ventral surface covering of fine denticles giving the skin a velvety feel. Notoraja sereti differs from all of these species in having a shorter snout (preorbital length 10.1–11.1 vs. 11.5–14.5% TL, prenasal length 8.2–8.9 vs, 9.8–12.1% TL), shorter head (dorsal head length 15.2–16.2 vs. 17.1–19.3% TL, ventral head length 21.6–22.9 vs. 22.9–25.9% TL), fewer pectoral-fin radials (total radials 58–60 vs. 61–74), and fewer vertebrae (predorsal diplospondylous centra 66–71 vs. 72–82, predorsal centra 90–95 vs. 98–107, total centra 126–131 vs. 135–152).

A New Species

The taxonomy and distribution of Pacific Annonaceae are reviewed in light of recent changes in generic delimitations. A new species of the genus Monoon from the Solomon Archipelago is described, Monoon salomonicum I.M.Turner & Utteridge sp. nov., together with an apparently related new species from New Guinea, Monoon pachypetalum I.M.Turner & Utteridge sp. nov. The confirmed presence of the genus in the Solomon Islands extends the generic range eastward beyond New Guinea. Two new species of Huberantha are described, Huberantha asymmetrica I.M.Turner & Utteridge sp. nov. and Huberantha whistleri I.M.Turner & Utteridge sp. nov., from the Solomon Islands and Samoa respectively. New combinations are proposed: Drepananthus novoguineensis (Baker f.) I.M.Turner & Utteridge comb. nov., Meiogyne punctulata (Baill.) I.M.Turner & Utteridge comb. nov. and Monoon merrillii (Kaneh.) I.M.Turner & Utteridge comb. nov. One neotype and four lectotypes are designated. The geographic patterns exhibited by nine native Annonaceae genera, that range in the Pacific beyond New Guinea, are discussed.

A New Species

Abstract A new species of long-legged sesarmid crab of the Leptarma leptosoma (Hilgendorf, 1869) species-group is described from mangroves in south-western India. In the general carapace features as well as in the proportions of the long ambulatory legs, L. biju n. sp. is most similar to L. gracilipes (Li, Rahayu & Ng, 2018), from eastern Indonesia and Papua New Guinea, but can easily be distinguished by the structure of the gonopods as well as the leg proportions.

A new Portholefish, Diplophos vicinia sp. nov., is described on the basis of nine specimens collected from the western Pacific Ocean by commercial midwater trawl. The new species, currently known only from the South China Sea and north of Papua New Guinea, can be easily distinguished from six nominal congeners by the combination of the following characters: dorsal-fin origin closer to snout than caudal-fin base, distance between last two AC photophores half that between preceding photophores, gill rakers 4 + 10–11=14–15, abdominal vertebrae 30–32, caudal vertebrae 44–45, total vertebrae 74–76, and the following photophore counts: IP 13–14, PV 18–19, IV 31–32, VAV 12–13, AC 37–39 + 2, and IC 83–86.

S. munroi, sp. nov.. is described from northern Australia and southern Papua New Guinea. It has been confused with S. niphonius of the north-western Pacific because both are spotted species with many (19-22) dorsal spines. S. niphonius is unique among the 18 species of the genus in having a straight intestine; S. munroi, like most other species of Scomberomorus, has two loops and three limbs to the intestine. S. munroi has more vertebrae (50-52) than S. niphonius (48-50) and most other species of Australian Scomberomorus (S. commerson 42-46, S. queenslandicus 48-49, S. semifasciatus 44-46), except for S. multiradiatus from Papua New Guinea (55-56). S. munroi has a deeper body and a longer postorbital distance than S. niphonius.
