Pseudoscorpions (Arachnida, Pseudoscorpiones) from French Polynesia with first species records and description of new species.

A new species Olpiumcaputisp. nov. from Tahiti is described here based on external characters. This is the first record of the family Olpiidae Banks, 1895 from French Polynesia. Additionally, the genus Paratemnoides Harvey, 1991 is recorded from French Polynesia for the first time with the full description of new-found specimens of Paratemnoidesassimilis (Beier, 1932). New localities of Geogarypuslongidigitatus (Rainbow, 1897) are added. An identification key to pseudoscorpions of French Polynesia is provided.

Synthesis of the Brazilian Poduromorpha (Collembola: Hexapoda) with Special Emphasis on the Equatorial Oceanic Islands.

We present new species and records of Poduromorpha for the Brazilian oceanic islands and synthesis of this order in Brazil. Friesea noronhaensis sp. nov., Friesea rochedoensis sp. nov., Willemia insularum sp. nov. and Paraxenylla zeliae sp. nov. are described and a diagnosis of the morphospecies Acherontiella sp. Lima and Zeppelini 2015 is provided. We present comparative tables, distribution and taxonomic keys of the Friesea, Arlesia, Brachystomella, Acherontiella, Paraxenylla, Xenylla, and Willemia found in the Brazilian oceanic islands and their respective congeners recorded in Brazil.

The ground beetles (Coleoptera, Carabidae) of southern Kuril Islands, Russia.

BACKGROUND: We compiled a list of the ground beetles that have been confirmed to occur to date in the southern Kuril Islands, Russian Far East. The list includes 168 species, all of which are known from Kunashir Island and the species richness on the remaining islands ranges from 68 (Shikotan Island) to 21 species (Tanfil'eva Island). The species richness is shown to depend sublinearly on island area, this being unusual for island faunas (Triantis et al. 2011). NEW INFORMATION: A large part of data is published here for the first time on the records of ground beetles in the southern Kuril Islands with precise localities. This allows not only the taxonomic composition of the faunas, but also the composition of local faunas to be discussed.

Brazilian Archisotoma Linnaniemi (Collembola, Isotomidae), with description of a new species from an oceanic atoll.

We summarize the distribution and habitat of Brazilian Archisotoma species, a taxonomic key for all species of the genus is given and a new species is described from intertidal sand of the Biologial Reserve Atol das Rocas, Brazil. Archisotoma jariani sp. nov. belongs to the besselsi group, recognized by small size, tibiotarsus III with stiff outer spur, maxillary head with thin simple capitulum, 3-2 pairs of trichobothria on abdominal segment VI. This is the first species of Collembola recorded from Atol das Rocas.

X-ray microtomography provides first data about the feeding behaviour of an endangered lizard, the Montserrat galliwasp (Diploglossus montisserrati).

Reporting the diet of recently extinct or very rare taxa, only known by a few museum specimens, is challenging. This study uses X-ray microtomography, a non-destructive investigation method, to obtain the first data about feeding behaviours in the Montserrat galliwasp (Diploglossus montisserrati) by scanning one of the two specimens known to date. The scans revealed the occurrence of shell fragments of a freshwater snail (Omalonyx matheroni) in the digestive tract of the specimen. This data combined with morphological evidence shows the occurrence of a durophagous feeding habit and a possible tendency of association with freshwater environments. This information could be crucial to save this critically endangered lizard endemic on Montserrat island.
