- Abstract:
- ... A new species of Dracoderes, Daracoderes spyro sp. nov., is described from Hispaniola Island (Caribbean Sea), and represents the first record of this genus in American waters. The new species is distinguished from its congeners by the presence of lateroventral spines on segments 3–4 and 6–9, lateral accessory spines on segment 5, lateroventral tubes on segments 2, 5 and 10, and laterodorsal tubes ...

- Abstract:
- ... A new kinorhynch species, Echinoderes kohni sp. nov., is described from the San Juan Archipelago, northwest Washington State, USA. The species’ spine/tube distribution combined with the presence of long, spiniform tergal extensions assign it to the Echinoderes spinifurca species group. It is distinguished from other species in the group by its enlarged fringe tips on the posterior sternal plate ma ...

- Abstract:
- ... Kinorhynch specimens were studied from abyssal sediment samples collected during seven cruises at the Clarion-Clipperton Fracture Zone (Eastern Central Pacific), a vast area that will be mined for polymetallic nodules in a near future. This study is the first in a series focused on kinorhynchs mainly collected at the German zone following requirements of the International Seabed Authority (ISA), w ...

- Abstract:
- ... Kinorhyncha is usually one of the more neglected groups in meiofauna ecology. Although their presence is frequently reported in a number of ecological meiofaunal studies, knowledge on their taxonomic composition and distribution at the local and regional scale is very limited. Particularly for the Arctic region, no comprehensive ecological description of kinorhynch communities has yet existed. To ...

- Abstract:
- ... Caves are natural laboratories to investigate evolutionary processes in the ocean. In contrast to the many described lineages of cave exclusive crustaceans and annelids, very little is known about cave scalidophorans. We here describe two new species of kinorhynchs from a lava tube in the Canary Islands and a cenote in the Yucatan Peninsula. Leiocanthus bretti sp. nov., from Tenerife, is mainly ch ...

Of these, Echinoderes kaempfae sp. nov. and Echinoderes schwieringae sp. nov. are described as new species. Echinoderes multiporus originally found on Eratosthenes Seamount, Mediterranean Sea, and Echinoderes cf. adrianovi originally found ...

A new species of Kinorhyncha, Triodontoderes lagahoo sp. nov., is described from Tobago Island, Caribbean Sea (western Atlantic Ocean) from a coastal, sandy habitat using both light and scanning electron microscopy. The species is characterized by the presence of middorsal acicular spines on segments 1–11 (that on segment 10 crenulated in males), laterodorsal crenulated spines on segment 10 only i ...

We assign the larvae to four groups according to their lorica pattern, which consists of platelets created by ridges. In larvae of the first group the platelets in the middle region of the lorica interdigitate in a zig-zag way, this has been described only for Priapulopsis a ...

Even in extreme physical conditions, which can limit fauna occurrence and distribution in environments such as intermediate sandy beaches, several meiofaunal organisms exhibit high abundance, meanwhile, the kinorhynchs occurrences are scarce in these habitats. We described the abundance and distribution of the kinorhynch Franciscideres kalenesos on two intermediate-dissipative sandy beaches of Sou ...

- Abstract:
- ... Since its discovery in the mid-1950'ies, Cateria has been an enigmatic kinorhynch genus due to its aberrant worm-like shape and extremely thin cuticle. However, the rare occurrence of the species, only found in sandy intertidal habitats, and the poor preservation of the type material have hampered detailed studies of the genus over time. Now, sixty years after the original description of Cateria s ...
