Spirogyromyces vermicola is described as a new genus and species inhabiting the gut of free-living nematodes. The spores are ingested and attach to the gut wall of the host. A stout, helicoid, septate hypha grows down the gut and produces one or several helicoid branches. One or more filiform spores arise from the vicinity of each septum and coil around the main axis or its branches. The mature thallus can fill the gut of the nematode with primary (main axis), secondary (branches), and tertiary (spores) coils of striking symmetry. Spores break away from the thallus and are defecated through the anal orifice to the exterior where they are eventually ingested to initiate infection.

Crustacean Host

The new genus and species, Dicrotrichura tricincta, is described from deep mud (1220 m) in the Ligurian Sea (western Mediterranean). It is the first tantulocaridan not found to be attached to a crustacean host but free living in the sediment. It is assigned to the Deoterthridae on the basis of the absence of a rostrum, the abdominal segmentation and the characteristic cephalic pore pattern. It can be distinguished from all known tantulocaridans in the presence of peculiar, bi-articulated caudal setae and the difference in thoracopodal setation between leg 2 and legs 3–5. Some new structures located on the attachment disc are described for the first time. D. tricincta is the second tantulocaridan to be recorded from the Mediterranean.

Molecular Comparison

A single ovigerous female specimen of marine shrimp of the family Palaemonidae collected from Madang Province, N.E. Papua New Guinea, was recognized as a representative of a new genus and species. Due to the presence of a sternal thoracic process, 3 pairs of posterior telson cuspidate setae, and the simple ambulatory dactyli, as well as the lack of branchiae on the two posterior maxillipeds, the new species clearly belongs to the assemblage of primarily free-living palaemonid taxa surrounding the speciose genera Cuapetes and Palaemonella. As the specimen possesses a short leaf-like rostrum, slender second pereiopods with small chelae similar to and not noticeably longer than the first pereiopods and very slender simple ambulatory dactyli, the specimen is without parallel within this assemblage and clearly represents a new genus. Its position within the Cuapetes/Palaemonella lineage of genera is also confirmed by a molecular comparison. The specimen is described and illustrated as a new genus and species.

Abstract A new genus and species, Chicosciencea pernambucensisgen. nov., sp. nov., is described from two localities along the coast of Pernambuco state, northeastern Brazil. Considering the unresolved situation of the families of Stenopodidea in previous studies, the position of this new genus is discussed based on morphological, molecular (16S mtDNA), and ecological data. The morphological analysis revealed that Chicoscienceagen. nov. differs from all stenopodidean genera by a combination of characters. The inferred molecular phylogeny recovered a monophyletic group including Chicoscienceagen. nov., MacromaxillocarisAlvarez, Iliffe & Villalobos, 2006, and MicroprosthemaStimpson, 1860, which comprise free-living (i.e., not-sponge associated), shallow-water species. Based on this monophyletic group and on their morphological and ecological similarities, we herein formally propose the resurrection of Macromaxillocarididae Alvarez, Iliffe & Villalobos, 2006 to include those genera. We also provide an updated world list of Stenopodidea. With the description of Chicoscienceagen. nov., the infraorder Stenopodidea now comprises 13 genera and 92 species.

A new genus and species, Termitocnemis huangi gen. et sp. nov., of the tenebrionine tribe Amarygmini Gistel, 1848 is described from Fujian Province, southeastern China. All specimens were collected from a healthy nest of the termite genus Nasutitermes Dudley, 1890, implying that this species is truly termitophilous. Transitional habitus characters of the new species shed further light on the evolution of amarygmine beetles from free-living to termitophily. Given the discovery of this new genus a revised key is provided to the Oriental genera of termitophilous Amarygmini.

Allogynaspis flechtmanni n. gen., n. sp. is described from litter bordering a stream in a forested area of Itatiaia National Park in southeastern Brazil. Although it shares a number of traits with the free-living macrochelid genera Nothrholaspis and Macrholaspis, the new species presents a unique combination of characters that argues against its inclusion in either genus, or in any other recognised macrochelid genus. A dichotomous key that distinguishes Allogynaspis from related macrocheline genera is included in the text.

Abstract A new genus and species of carneyellid edrioasteroid, Spiracarneyella florencei n. gen. n. sp., is described from the Upper Ordovician (Kaitian) Point Pleasant Formation of northern Kentucky and southern Ohio. Spiracarneyella n. gen. is characterized by having all five ambulacra curving clockwise around the theca, having small node-bearing interambulacral plates in the distal interambulacra, and having the periproct placement slightly offset to the right side of the CD interambulacrum. The oral area of carneyellids evolved by paedomorphosis of the oral plates covering the mouth. The straight ambulacra of Cryptogoleus and the spiraling ambulacra of Spiracarneyella n. gen. evolved by paedomorphosis and peramorphosis, respectively.
