Two new species of asellote isopods from the waters surroundng the San Juan Archipelago are described and diagnosed. Baeonectes improvisus n. gen., n. sp. and Acanthamunnopsis milleri n. sp. belong to the highly evolved, natatory families Eurycopidae and Munnopsidae, respectively. Baeonectes, a circum-arctic and boreal shallow-water genus, also includes B. muticus (Sars), the type-species. The taxonomic concept of Acanthamunnopsis has difficulties that must be resolved before A. milleri can be described. To this end, the family Acanthamunnopsidae Schultz is invalidated and merged with the Munnopsidae; the genus Acanthamunnopsis Schultz is revised; and A. hystrix, the type-species, is redescribed with corrections and additions to the original description. The unusual presence of the bathypelagic genus Acanthamunnopsis in the surface waters of the San Juan Archipelago is discussed. Acanthamunnopsis milleri is tentatively postulated to be a deep resident of the open ocean that was carried landward into the Strait of Juan de Fuca by upwelled intrusions of cold, saline water.

Abstract The genus Paratrygon, currently recognized as the sole monotypic genus of the family Potamotrygonidae, has a considerably greater diversity than previously indicated, including molecular studies, which supported P. aiereba (hitherto the only recognized species in the genus) as a possible species complex. Here we describe two new species of the genus that are both endemic to and sympatric in the Orinoco basin. Paratrygon aiereba, type species of the genus, is now restricted to the Amazon basin. Both new species are identified and defined through morphological characters such as coloration, dermal denticle morphology, arrangement of thorns, distribution and morphology of ventral lateral line canals, morphology of skeletal elements, and morphometrics. An extensive comparison of these characters between the new species herein described and P. aiereba is presented. Finally, a taxonomic reappraisal of P. aiereba is provided through a revision of preserved material and its original description, plus new evidence about its type-locatity, collectors, and a reconsideration of the destination of its type-specimen.

Two New Species

The Australian species of the small heterogastrid genus Parathyginus Scudder, 1957 have been reviewed, resulting in the establishment of the junior subjective synonymy of P. doddi (Distant, 1918) with P. signifer (Walker, 1872), and the description of two new species, P. australis sp. nov. and P. acuminatus sp. nov. A redescription of the genus is provided with emphasis on male and female genitalia characters, along with a key to all included Australian species. Male genitalia, particularly the details of the aedeagus, have been rarely studied in this genus or for that matter the family Heterogastridae particularly due to the difficulty in inflating the inflatable sections. In this study, therefore, an attempt was made to fully inflate and describe the aedeagus of all the species included in this contribution, as well as of Heterogaster urticae (Fabricius, 1775), the type species of the oldest genus Heterogaster Schilling, 1829, of the family Heterogastridae.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.

The new genus Cyclacanthia n.g. is erected in the poecilosclerid Family Latrunculiidae for the type species Latrunculia bellae Samaai & Kelly, 2003, and two further species, Cyclacanthia cloverlyae sp. nov., and Cyclacanthia mzimayiensis sp. nov.. The latter species are from the subtropical east coast of South Africa, whereas C. bellae has only been found further south in warm temperate Algoa Bay. Cyclacanthia n.g. differs from other Latrunculiidae genera in the ontogeny, morphology and structure of the mature microsclere, the isospinodiscorhabd, which has only three major whorls of projections as opposed to the four in species of Latrunculia du Bocage. Additional diagnostic characters include the presence of broad swathes of megascleres that diverge from the base of the sponge towards the upper choanosome, where they form loose brushes and the typical whispy reticulation of most Latrunculiidae. The ectosome is composed of a dense tangential layer of megascleres, an irregular palisade of microscleres at the surface, and a permanently encrusting habit. Cyclacanthia n.g. is the second new latrunculid genus recently described from shallow subtidal South African waters, following major revision of the family. The presence of species in four of the five known genera in the family, on South African coastlines, suggests a diversity hot-spot for the family in this region.

Argentine Basin

Two new species of Ischnomesidae, Haplomesus celticensis sp. nov. and Haplomesus hanseni sp. nov. are described from the southwest of Ireland and the Argentine Basin respectively. Both species lack the expression of pereopod VII, a characteristic that we argue is produced by progenesis, not neoteny as suggested by Brökeland & Brandt (2004). Haplomesus angustus Hansen, 1916 and Haplomesus tropicalis Menzies, 1962, also lack pereopod VII and are revised from the type material. The original description of Haplomesus angustus Hansen, 1916 describes the adult type specimen as a juvenile; the original description of Haplomesus tropicalis Menzies, 1962 fails to mention the lack of pereopod VII. Progenesis is discussed for the above species and within the family Ischnomesidae as a whole.

History Of

The genus Anystipalpus Berlese, 1911, of uncertain prior placement in the superfamilies Ascoidea or Dermanyssoidea, is redescribed, based on reexamination of type and other material of the type-species, A. percicola Berlese, and of material representing Anystipalpus livshitsi (Eidelberg) new combination and two new species, A. labiduricola n. sp. and A. kazemii n. sp. Anystipalpus nataliae (Eidelberg) new combination and Anystipalpus ukrainicus (Sklyar) new combination are determined to be junior synonyms of A. percicola Berlese and A. livshitsi (Eidelberg), respectively, new synonymies. The genus is known thus far only from adult females phoretic under the elytra of carabid beetles and the tegmina of labidurid earwigs in Eurasia. The relationships between it and the closely related Antennoseius Berlese, 1916 and Vitzthumia Thor, 1930, are reviewed, and the options for the family level placement of these genera are reconsidered. Attention is given to some gnathosomatic attributes that are commonly overlooked in description of species of these closely related genera. Phoresy and the role of adult female morphs in the life history of these mites, as well as the extraordinary phoretic association of one species with earwigs are discussed.

We describe a new feather mite genus Atelophyllodes gen. n. (Proctophyllodidae: Proctophyllodinae) with two new species from lyrebirds (Passeriformes: Menuridae) in Australia: Atelophyllodes menurae sp. n. (type species) from Menura novaehollandiae Latham, 1802, and A. atyeoi sp. n. from M. alberti Bonaparte, 1850. The unique features of Atelophyllodes that differentiate it from all other described genera of the subfamily Proctophyllodinae involve the structure of opisthosomal lobes in males: lobes are short and wide, with three pairs of extensions bearing bases of setae h2, h3 and f2, and lack terminal lamellae on their posterior margins.

Two New Species

Two new genera in the family Lycosidae Sundevall, 1833 from Argentina are proposed. Lobizon gen. nov. comprises five species: Lobizon corondaensis (Mello-Leitão, 1941) comb. nov. (type species), L. minor (Mello Leitão, 1941) comb. nov., and L. humilis (Mello-Leitão, 1944) comb. nov., all these with a wide distribution in Argentina, and two new species: L. ojangureni sp. nov. from the montane forests of Northwestern Argentina, and L. otamendi sp. nov. from the northeastern Buenos Aires Province. The monotypic Navira gen. nov. is erected for N. naguan sp. nov. from Córdoba and San Luis Provinces. Trochosippa anomala (Mello-Leitão, 1945) and Alopecosa unguiculata Mello-Leitão, 1944 are considered junior synonyms of L. corondaensis and L. humilis respectively. A putative synapomorphy uniting the two genera is the massive, greatly elongated terminal apophysis which is grooved along its length. The subfamily placement of the two new genera is briefly discussed, and it is concluded that they probably belong to the Artoriinae Framenau, 2007 or Venoniinae Lehtinen & Hippa, 1979.

Two New Species

The genus Drylichus Heller, which has not been treated since the original description in 1916, is reviewed taxonomically. The type species, Drylichus hylesinoides Heller (New Caledonia), is redescribed. Two new species, D. fidelitas sp. nov. (Lifou Island) and D. monteithi sp. nov. (New Caledonia), are described. Drylichus is hypothesized to be closely related with Parnida Broun (New Zealand), with which it shares the following characters: (1) shape of mouthparts and gular region, (2) distribution and morphology of sensilla on mouthparts, (3) configuration of antennomeres, (4) correspondence of several types of antennal sensilla, (5) shape of ventral sclerites of thorax and abdomen.
