A New Species

Dysommina orientalis, a new species of Ilyophine eel from off Taiwan and Japan is described and illustrated. The species had long been recognized as Dysommina rugosa in the western Pacific and is distinguished from D. rugosa by a lower number of predorsal vertebrae, a higher number of total vertebrae, shorter head length, smaller eye size, reduced vomerine dentition, and an increased number of both mandibular and maxillary teeth, as well as significant differences in DNA sequence in COI and 16S.

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

Homalopsid snakes are monophyletic and contain two major subclades: a fangless clade and rear-fanged clade. They are distributed in South Asia, Australasia, and the Western Pacific. The fangless clade is restricted to the eastern Indonesian Archipelago and the island of Sumatra and is poorly known in terms of its natural history. Molecular data support the eastern Indonesian fangless endemic genus Brachyorrhos as the sister to the rear-fang clade. Here we recognize the identity of the Brachyorrhos population from the island of Morotai as B. wallacei and describe a new species of dwarf Brachyorrhos from the island of Seram, Malukus, Indonesia. The new species can be distinguished from all congeners by a lower number of ventral scales, the presence of a preocular scale and a loreal scale, as well as its exceptionally diminutive size. The new species is a candidate for the smallest alethinophidian snake. The three fangless genera, Brachyorrhos, Calamophis, and Karnsophis, have been suggested to form a clade of homalopsid snakes restricted to the Indonesian Archipelago, and we discuss their biogeography.

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

Munidopsis myojinensis n. sp., herein described and illustrated from Myojin Knoll and Northwest Eifuku Seamount in the Western Pacific, is the tenth species of Munidopsis known to be associated with active hydrothermal vents. It resembles M. starmer Baba & de Saint Laurent, 1992 in general ornamentation and spination of the body but differs in the erectness of the eyespine and form of the telson plates. Information on genetic identification using mitochondrial sequences (COI) is provided. Distributions of the vent associated Munidopsis in the Western Pacific and the habitat of the new species are briefly described.
