A New Species

A new megacanthoxea- bearing tetillid Acanthotetilla celebensis sp.nov. (Porifera: Demospongiae: Spirophorida: Tetillidae) is described from North Sulawesi, Indonesia. The new species is compared with all other (four) Acanthotetilla species occurring in the Indian Ocean and the West Indies. The new species differs from these other species by the overall morphology, and especially the presence of two sizes of megacanthoxeas. This is the first record of Acanthotetilla in Indonesia.

A New Species

The genus Smacigastes Ivanenko & Defaye, 2004 (Harpacticoida, Copepoda) is the most primitive genus in the family Tegastidae Sars, 1904, occurring in deep-sea chemosynthetic environments, such as hydrothermal vents, cold seeps, whale falls and wood falls. Our exploration of the Onnuri Vent Field, the sixth active hydrothermal vent system in the Central Indian Ridge, resulted in the discovery of a new species in the genus Smacigastes. A detailed morphological analysis of S. pumilasp. nov. reveals that it most resembles S. barti Gollner, Ivanenko & Martínez Arbizu, 2008, described from a hydrothermal vent in the East Pacific Ridge; the new species can be distinguished from the existing species by the 8-segmented female antennule, the absence of an abexopodal seta on the antennary basis, the mandibular exopod represented by a single seta and the exopod of the first leg with five setae. This is the first record of Smacigastes in the Indian Ocean. A dichotomous key to species of the genus Smacigastes worldwide is provided.

A New Species

The new species Dicranocentrus paramoense, D. bidentatus, Heteromurus (Heteromurtrella) echinatus and H. (H.) pruinosus are described from specimens collected in the State of Mérida, Venezuela. A new species of each genus comes from a cloud forest near the city of Mérida and a new species of each taxon was collected in paramos northeast of Mérida. Congeneric species are phyletically very near and their closest relatives live in Central America and the West Indies. Dicranocentrus bidentatus is the sole species of its genus with only two teeth (the basal pair) along the inner margin of the unguis. Heteromurus (Heteromurtrella) echinatus is unique among members of its subgenus in possessing dental spines, although some individuals lack these structures. This is the first record of such intraspecific variation. Four tables detail variations of a number of characters and 41 figures complement the text.

A New Species

The crustacean order Thermosbaenacea is reported for the first time from the Southern Hemisphere, from almost fresh water in a cave habitat in tropical Western Australia. Halosbaena tulki, sp. nov. belongs to a genus previously known only from saline waters in the West Indies, Columbia and Canary Is. The discovery is consistent with a very ancient origin of the order and distribution of the genus by plate movements following the breakup of Pangaea.

A New Species

<em>Diplacodes lefebvrii</em> (Rambur, 1842) is a libellulid dragonfly, which is common and widespread in Africa and across the Indian Ocean. While this species is fairly common in the south and east of the Mediterranean, its European range is confined to Cyprus, the island of Rhodes and the south of the Iberian Peninsula. Here we report the first record of <em>D. lefebvrii </em>for Italy, which was captured near Cagliari (Sardinia) on 11.IX.2013. In October 2014, a population of the same species was observed at a small wetland on the island “Isola di San Pietro” (Sardinia). Here the observed sex ratio of <em>D. lefebvrii</em> was strongly biased in favour of females and only a single male was observed.
