ABSTRACT Common in Vanuatu, the Dwarf Sea Krait Laticauda frontalis also is known from five old records (in the 1880s and 1890s) from the Loyalty Islands, between Vanuatu and the main island of New Caledonia. Those records have been interpreted by some authorities as errors, or as reflecting occasional waifs rather than breeding populations. We now report an additional specimen of L. frontalis from the Loyalty Islands island of Maré, and we review distributional data for this species and for the closely allied L. saintgironsi. Sympatry on the western coast of Maré confirms that these two taxa warrant separate species status despite their minimal genetic divergence.

Revision of the genus Latrunculia du Bocage, 1869, has resulted in 27 of 36 species considered to be valid. Many species have been reassigned to genera in the poecilosclerid family Podospongiidae, in particular, and many have been transferred to other Latrunculiidae genera. Latrunculia apicalis var. biformis (Kirkpatrick 1908) and Latrunculia apicalis var. basilis (Kirkpatrick 1908) have been elevated to full and separate species status, as L. biformis Kirkpatrick and L. basilis Kirkpatrick. Two new species have been described, from New Caledonia (L. novaecaledoniae sp. nov.) and the northeastern Pacific (L. austini sp. nov.). This revision also formally recognizes the two morphological subgroups triverticillata and spinispiraefera hypothesized by Alvarez et al. (2002), as the new subgenera Latrunculia (Latrunculia) subgen. nov. and Latrunculia (Biannulata) subgen. nov.. The primary distinction between these two groups is the morphology of the anisodiscorhabd microscleres. The anisodiscorhabds of Latrunculia (Latrunculia) species have a basal whorl just above the manubrium in addition to two centralized whorls of projections. The anisodiscorhabds of Latrunculia (Biannulata) species lack this basal whorl. There is some indication that there are geographic and habitat differences between the two groups.

Morphological Differences

The Thamnophilus punctatus complex has been recently reviewed on the basis of morphological and vocal characters, and is divided in six different species. Two of the new species, although well defined on the basis of morphological differences, could not be unambiguously distinguished through their loudsongs. The Planalto Slaty-antshrike (Thamnophilus pelzelni) and the Sooretama Slaty-antshrike (T. ambiguus) are most easily distinguished by subtle and localized changes in plumage colors of males and females. In the present study we used sequences of the control region, Cytochrome b, and ND2 genes, of the mitochondrial DNA (mtDNA) to evaluate the levels of molecular differentiation between these two species. The mean pairwise distance between the two species was 3.8%, while it varied from 2.7% to 4.9% for each mtDNA region. Although extensive variation was also detected among haplotypes within species, especially for T. ambiguus, we suggest that the genetic divergence found between T. ambiguus and T. pelzelni is high enough to corroborate the separate species status of these two antbird taxa.

The systematic position and modern state of populations of the rare species of Ukrainian flora Carlina cirsioides Klokov (Asteraceae) are considered. Since this species is included into the Red Data Book of Ukraine (2009) and the European List of Globally Threatened Animals and Plants (1991), it is well-known for European botanists as an endemic of the Ukrainian flora. However, neither the authors of Flora Europaea (1976), nor monographers of the genus Carlina recognize Carlina cirsioides as a separate species. Comparative morphological, chorological, and coenotic analyzes does not allow Carlina cirsioides to be considered as a separate species, endemic and relic of the Ukrainian flora. According to morphological features, specimens from the plains of Ukraine are referred to the subspecies Carlina acaulis caulescens, which is distributed mainly in plain regions of Europe. Ecological and coenotic conditions of habitats of Carlina acaulis in the lowland part of Ukraine are different from its habitats in the Carpathians and Alps and are close to xerotherme grass communities with Carlina acaulis of plains of Central Europe. Steppe communities of Festuco-Brometea class with Carlina acaulis in the Volhynian-Podolian Upland are similar to xerotherme communities with Carlina acaulis of Central Europe. Erico-Pinetea class communities are common habitats for Carlina acaulis in the Ukrainian Polissia and north-eastern Poland. Lowering the species status of Carlina cirsioides from separate species to subspecies Carlina acaulis caulescens does not diminish its phytosozological value. Due to the low number of Carlina acaulis populations in the Volhynian-Podolian Upland and Polissia, all localities of this species in the lowland part of Ukraine need to be provided by protection.

Geographic Populations

In the present study, we have examined the variability in Anopheles nuneztovari mitochondrial DNA of three populations from the Brazilian Amazon and one from western Colombia (Sitronela), using four restriction endonucleases (BclI, ClaI, HindIII, SstI). The haplotype diversity (h) was slightly elevated in all populations (0.5000 to 0.6765), whereas the nucleotide diversity (pi) was lower in the Sitronela population (0.0029) and higher in populations from the Brazilian Amazon (0.0056 to 0.0098). The degree of sequence divergence (delta) estimated within the Brazilian Amazon and that in Sitronela (0.0329 to 0.0371) suggests that these geographic populations of A. nuneztovari may eventually constitute separate species. The low sequence divergence values among the three Brazilian Amazon populations (0.0012 to 0.0031) indicate that these populations are genetically similar. These results are consistent with those recently reported for allozymes of these same populations.

The chrysomelid genus Bohumiljania Monrós, 1958, is revised, with nine species, seven new: B. aoupinie sp. nov., B. caledonica (Jolivet, 1957), B. lafoa sp. nov., B. humboldti Jolivet, Verma & Mille, 2005, B. mandjelia sp nov., B. tango sp. nov., B. xanthogramma sp. nov., B. xaracuu sp. nov., B. yuaga sp. nov. All species are described. The type species, B. caledonica, is shown to have been misidentified in recent literature. The original description of the other described species, B. humboldti, is shown to include at least three species. A key is provided for identification of Bohumiljania species, all of which are endemic to the main island of New Caledonia. Six of the species are known from just 14 specimens, suggesting that further species remain to be discovered. The morphology and biology of Bohumiljania is reviewed, including description of the larva.

A New Species

A new species of the synallactid sea cucumber genus Pseudostichopus is described, P. aemulatus sp. nov., based on genetic (DNA sequences of the mitochondrial gene Cytochrome Oxidase I [COI] gene) and morphological characters. A comparative molecular study with two other species of the same genus (P. villosus and P. mollis) and from a different family (Isostichopus fuscus) was carried out in order to clarify its taxonomic identity. The nucleotide distance between P. aemulatus sp. nov. and P. villosus and P. mollis is sufficient to support distinct species status. The estimated difference in the number of amino acids, coded for by a partially sequenced COI gene, within the species of the family Synallactidae ranged from 4 to 18. The phylogenetic analysis clearly supports separate species status of these sympatric morphotypes, as indicated by the morphological analysis.

High Diversity

The Oceanian country of New Caledonia has been shown to have a great diversity of Trichoptera, but prior to this work only 3 species from the large Leptoceridae genus Triplectides were known from there. Extensive sampling on the main island, Grande Terre, revealed 11 new species in the genus, as well as a male of the seemingly widespread species Triplectides australis. These 11 new species are here described and illustrated, and a key to males of the New Caledonian Triplectides species is provided. The new species are: T. mouiensis, new species; T. abnormalis, new species; T. minutus,new species; T. noumeiensis, new species; T. tigrinus, new species; T. koghiensis, new species; T. wardi, new species; T. nathaliae, new species; T. mariannae, new species; T. dawnae, new species; T. aequalichelatus, new species. Fifteen species within the genus are now known from New Caledonia; relative to land mass, this is a high diversity compared to the 25 species recorded from Australia.

Macroscopic Examination

Monthly samples of the bivalves Atactodea striata, Gafrariurn turnidum and Anadara scapha were collected over 1 year from the littoral zone on the south-western coast of New Caledonia. A. striata and G. turnidum were studied by macroscopic examination of gonads and microscopic examination of gamete smears. For A. scapha, only microscopic examination was used. A. striata and G. turnidum are dioecious, whereas A. scapha is a protandric hermaphrodite. Sexual differentiation begins at a shell length of 20 mm for A. striata and G. turnidum and 22 mm for A. scapha. The three species have an extended or continuous breeding period, although, in all three, sexual activity peaks in the hot season.
