The new liverwort species Chiastocaulon raetzelii is described from New Caledonia. Chiastocaulon raetzelii is characterized by very fragile, caducous leaves, stems therefore often becoming completely denuded of leaves; only bract leaves of the androecia are permanent and often the only ones remaining on the stem. Plants are minute with leafy shoots to 1 mm wide. Leaves on leafy shoots are arranged in opposing pairs, they are obovate-truncate to spathulate, with 3–7 teeth per leaf, teeth are filiform, consisting of long rectangular cells, and occupy about 1/3 to 1/4 of the entire leaf length. The species is compared to C. oppositum and C. geminifolium, which are the most similar morphologically.

Leptochelia Vatulelensis(Crustacea: Tanaidacea), A New Species From Anchialine Caves of the South-Western PacificLeptochelia vatulelensisn. sp., discovered on the small islands of Vatulele (Fijian group) and Ouvéa (Loyalty Islands, New Caledonia), is described and illustrated. The new species is distinguished from the others of the"Leptochelia-dubiagroup" (to which it is generally similar) by the following combination of morphological characteristics: (1) the presence of three to four distal setae on the maxilliped basis; (2) merus of pereopods III and IV with only a distosternal seta; (3) endopod of the uropods formed of four (rarely three) articles; (4) males with two (sometimes three) relatively short aesthetascs on the first five articles of the antennular flagellum; (5) male cheliped with a diminished dimorphism; (6) males with a vertical comb-row of setae on the cheliped propodus. Although it inhabits inland, anchialine caves, the new species lacks morphological features that are characteristic of some cave species.

The amphipod genus Sebadexius Ledoyer, 1984 (New Caledonia) is reviewed, based on new material from Cebu in The Philippines. Some characters are re-interpreted, and a new species, Sebadexius cebuense, is described.

Three endemic species of Xyris (Xyridaceae, Poales) are currently recognized in New Caledonia. A recent multivariate analysis of 18 morphological characters based on 129 specimens of Xyris from New Caledonia, supported by 10 anatomical and micromorphological observations, suggested that three species should be recognized in the New Caledonian archipelago. However, the three published names did not correspond to the three entities identified via the multivariate analyses. The results showed that Xyris neocaledonia Rendle was morphologically distinct but requires lectotypification, Xyris guillauminii Conert was indistinct from X. pancheri Rendle, and that a new morphologically distinct species required description. We therefore propose to clarify the taxonomy of the genus for New Caledonia, by designating a lectotype, making this synonymy and describing the new species. The new species, Xyris desquamatus J.R.Morel & Munzinger, sp. nov., has the remarkable feature of leaves that are shed as the plant senesces, and is reflected in the specific epithet for this new species. Line drawings are provided for the new species, along with colour photos for the three New Caledonian Xyris species and a distribution map. Three identification keys are provided, the first based on vegetative characters, the second on reproductive characters and the third on anatomical features of the leaf. Xyris desquamatus is preliminarily assigned an IUCN risk of extinction assessment of vulnerable.

Xanthochorema neocaledonia sp.n.is described from New Caledonia, raising to seven the number of Hydrobiosidae (Trichoptera) species now known from New Caledonia. A key for discrimination of males of these seven species is presented, and distributional maps are included for all species. In addition, new records are included for Xanthochorema bifurcatum Schmid, 1989, Xanthochorema calcaratum Schmid, 1989, and Xanthochorema celadon Schmid, 1989.

A new species of Nyctophilus is described on the basis of three specimens from the hinterland of Noum�a, New Caledonia. Comparisons are made with a large series of the most similar species, N. gouldi and N. bifax from eastern Australia, from which it differs on external, cranial, dental and penile morphology. The new species most resembles N. gouldi and its affinities appear to lie within the Australian fauna. An IUCN threat category of ?Vulnerable? is suggested due to a localised distribution in threatened high elevation rainforest.

Tricholapita Gómez-Zurita and Cardoso nom. nov. is proposed as the replacement name for the leaf beetle taxon Lapita Gómez-Zurita and Cardoso, 2014, nec Bickel, 2002. Moreover, the rank of Tricholapita stat. nov. is elevated from subgenus of Taophila Heller, 1916 to generic status. Phylogenetic evidence based on mtDNA rrnS sequences and diagnostic morphological characters reveals a new species from the south of Grande Terre in New Caledonia, which is described: Tricholapita reidi sp. nov.

A new species of Cyphophthalmi belonging to the New Caledonian endemic genus Troglosiro Juberthie, 1979 is described and illustrated using SEM, including the first description of a troglosironid ovipositor. T. longifossa sp. nov., known only from its type locality in Port Boisé, and found at low elevation near sea level, constitutes the seventh species of Troglosiro to be described to date. The new species has a unique disposition of the four ventral opisthosomal gland pores in the anterior portion of a long depression of the sternal segments 3 to 7. Information on other specimens recently collected in New Caledonia indicates that the number of described species in the island is a gross underestimate of the real diversity of New Caledonian Cyphophthalmi, both in number of species and morphology.
