Microhabitat Segregation

Seven new species of the planktonic copepod genus and subgenus Tortanus (Atortus) are described from North Sulawesi, Indonesia. Four of these species, T. (A.) indonesiensis, T. (A.) omorii, T. (A.) processus and T. (A.) lukmani, belong to the brevipes species complex sensu Ohtsuka & Kimoto (1989). Two species, T. (A.) sulawesiensis and T. (A.) manadoensis, can be placed in the recticauda species complex. The seventh species, however, T. (A.) bilobus, belongs to neither group, which will necessitate a revision of the current morphology-based grouping with the aid of a genetically-based phylogeny. The co-occurrence of multiple closely-related congeners in a relatively small area suggests possible microhabitat segregation among these species.

A New Species

Aiphanes argos is a new species of palm segregated from Aiphanes parvifolia, which is now recognized to be a species complex. Aiphanes argos is one of the few rheophytic members of the palm family, and is endemic to a small area in the Samaná Norte River canyon in Antioquia, Colombia, where it is critically endangered because its populations are threatened by the damming of the river for a hydroelectric plant. The epiteth argos is the name of the conglomerate that intends to build the dam, and is given to the palm as a plea for the conservation of the Samaná Norte River canyon.

High Diversity

A new species of the planktonic copepod Tortanus (Atortus) (Calanoida: Tortanidae), T. (A.) magnonyx is described from the Seychelles, Mauritius and Madagascar. This is the sixth species of the Indian Ocean recticauda species group, of the Indo-West Pacific recticauda species complex, that has been described from the western Indian Ocean. The inshore areas where these copepods are found have been poorly surveyed, so the number of species found implies a high diversity.

A New Species

Mangroves create unique ecological environments, furnishing a habitat opportunity for many species. The majority of published information on mangrove sponges comes from the Caribbean while few data are available from Indo-Pacific mangrove sponges. In general, species diversity of sponges in mangroves is lower than adjacent subtidal habitats in both the Caribbean and Indo-Pacific. The aim of this study is to report the first data about sponge species diversity of two mangrove forests from Bangka Island (North Sulawesi, Indonesia) and to describe a new sponge species associated with the mangroves. The survey found 19 species, belonging to 11 families and 15 genera; the samples were collected on mangrove trunks, on the roots or on the surrounding bottom. The majority of the species are typical of coral reef but two of them have been previously found only in lagoons or in mangrove habitats. These new data enlarge our knowledge about Indonesian sponges diversity and suggest the urgency to consider Indonesian mangroves as an important but underestimated element in coral reef ecological dynamics.

Three New Species

Three new species of Megarthrus Curtis from mainland China belonging to the M. calcaratus species complex are described: M. bajie Liu & Cuccodoro sp. nov., M. wujing Liu & Cuccodoro sp. nov., and M. wukong Liu & Cuccodoro sp. nov.. Also pertaining to this lineage of Megarthus, the East Palaearctic M. zerchei Cuccodoro & Löbl is reported here to occur in China (new country record). These four species are diagnosed, illustrated, and keyed. Their distribution in mainland China is mapped, and their affinities are briefly discussed.

Two New Species

Margyricarpus pinnatus is a poorly understood entity from natural grasslands of South America that it better considered as a species complex. In this work we contribute to the advancement of the taxonomic knowledge of this challenging species complex by describing two new species of Margyricarpus from southern Brazil. We present field photographs, illustrations, a distribution map and ecologic and conservation notes on the new species.
