A New Species

A new species, Acropogonhorarius Gâteblé & Munzinger, sp. nov. (Malvaceae, Sterculioideae), is described from New Caledonia. It is known only from two very small subpopulations in the rainforests of the Petchécara Pass between Thio and Canala, in the southeast of Grande-Terre, New Caledonia’s main island. This shrub to small tree has hastate leaves and minute sessile tubular whitish-yellowish flowers and is strikingly different from all other members of the genus. The type locality is geologically complex and located within one of only four amphibolite lenses known in New Caledonia. A line drawing and colour photos are provided for the new species, along with a preliminary risk of extinction assessment, which indicates that the species is Critically Endangered.

A New Species

A new species of Euphorbiaceae, Bocquillonia corneri, narrowly endemic to the extreme north-east of New Caledonia’s main island, is here highlighted, described and illustrated, based on original morphological and architectural characteristics. This new species differs notably by its unique monocaulous tree habit, while other Bocquillonia species are ramified shrubs, small monocaulous shrubs or well reiterated trees. A previous identification key to Bocquillonia species is expanded to include this new species. Bocquillonia corneri is located in a very confined gully forest at low-elevation on volcano-sedimentary substrate. A preliminary IUCN conservation status of Critically Endangered (CR) is proposed.

A New Species

A new species, Acropogon mesophilus Munzinger & Gâteblé (Malvaceae, Sterculioideae), is described from New Caledonia. This species is endemic to non-ultramafic areas, along the southwestern coast of Grande-Terre. The species has large leaves, widely ovate to ovate, and entire, and might be confused with only two other endemic species, namely A. bullatus (Pancher & Sebert) Morat and A. veillonii Morat. However, A. mesophilus differs from the other two species most evidently by its leaves 3-nerved, flat, and with truncate to rounded bases, versus leaves 5-nerved, bullate, and with cordate bases. A line drawing and color photos are provided for the new species, along with a discussion of its morphological affinities and a preliminary risk of extinction assessment of Endangered.

A New Species

A new species of Planchonella, endemic to the Roches de la Ouaième in northeastern New Caledonia, is described and illustrated. Planchonella ulfii morphologically resembles P. roseoloba, while molecular data indicate a closer relation to P. minutiflora and P. koumaciensis, with all three species belonging to a clade characterized by ridged fruits. The new species brings the total for the genus to 37 species in New Caledonia, 36 of which are endemic to the archipelago. With a single known population comprising 10 individuals, a preliminary risk of extinction assessment using the IUCN Red List criteria indicates that it is Critically Endangered due to risk of fire faced by the shrubby vegetation found of the summit crest of the Roches de la Ouaième. The level of micro-endemism found at this site is discussed.

A New Species

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.

Primulina papillosa Z.B. Xin, W.C. Chou & F. Wen, a new species from limestone areas of Guangxi, China, is described and illustrated here. It morphologically resembles P. linearifolia (W.T. Wang) Yin Z. Wang and P. pseudolinearifolia W.B. Xu & K.F. Chung, but can be easily distinguished by some combined characters, especially its leaf blades densely papillose-hispid. We found only one population at the type locality with no more than 200 individuals, so that this new species is provisionally assessed as Critically Endangered (CR) using IUCN Criteria.

A New Species

The New Caledonian Archipelago is a hot spot for biodiversity and endemism. Whereas popular groups such as birds and plants are well-studied, invertebrate groups such as ostracods remain ill-known. Here, we re-describe Strandesia sanoamuangae Savatenalinton & Martens, 2010, originally described from Thailand (8000 km away from New Caledonia), and describe Strandesia mehesi sp. nov. Both species are known only from females. Material for the present study was collected from diverse aquatic non-marine habitats from Grande Terre, the main island of New Caledonia. Whereas S. sanoamuangae is seemingly easily identifiable, S. mehesi sp. nov. is part of the Strandesia vinceguerrae/vavrai species cluster in the genus, of which the ‘older’ species (described long ago) often have incomplete and superficial descriptions. Differentiation between the new species and the other members of this species cluster are based on small anatomical details of the valves. The current paper updates the known number of recent freshwater Ostracoda of New Caledonia from 14 to 16 species, although at least five of these species have an uncertain status.

A new Begonia species, Begonia makuruyot, from B. section Baryandra is described and illustrated from forests over limestone in Surigao del Norte. This distinctive species, which appears to be endemic to the type locality, inhabits shaded limestone walls along the Daywan River at an elevation of 10–50 metres above sea level. Begonia makuruyot is distinguished from other Philippine Begonia by its rugose laminae, pendent leaves, pilose petioles and stipules fused with fleshy, aristate trichomes that are occasionally branching. A comparison with the phenetically similar B. acuminatissima is provided. Based on IUCN Red List criteria, B. makuruyot is designated Critically Endangered (CR).

A new species of Cardiopteridaceae, Citronella hirsuta, endemic to the east-central part of New Caledonia’s main island, Grande Terre, distinguished on the basis of morphological evidence, is described and illustrated. This new species is distinguished by its densely hirsute leaves, while the two others species of Citronella occurring in New Caledonia have glabrous leaves. Citronella hirsuta is restricted to ultramafic substrate, and only known from areas that are situated within mining concessions. A preliminarily IUCN conservation status of Endangered (EN) is proposed.

A New Species

Based on our detailed observations in the field, completed with herbarium material of representatives of Hydrangea section Cornidia in southeastern Mexico and Central America, we found that Hydrangea steyermarkii Standley, in contrast to what has been assumed up to now, is restricted to the Tacaná Volcano on the border of Mexico and Guatemala. The majority of the specimens with reddish or whitish indument on their branches in South East Mexico and Central America, belonging to this nearly exclusively Neotropical Hydrangea clade, had been identified as such, but the characters of these collections do not coincide with the single type specimen of H. steyermarkii, neither with other individuals of this species growing in the type locality area. In fact, nearly all specimens of Mesoamerica that had been identified as this species belong to a new species with a relatively wide distribution, which we describe here. This new species is illustrated and compared with H. steyermarkii, of which we also provide an amended description and illustrations. Finally, on the basis of these two species we document previously suggested dioecism in this plant group, which not only has consequences for systematics and nomenclature in this clade, but also for conservation.
