This troglobitic milliped is of unusual interest because it is the type of a new genus and the first Mexican record of the family Trichopetalidae, which previously has been known from Nova Scotia to Louisiana, Oklahoma, and Colorado. If the genus has undergone speciation as related genera have, then additional species and subspecies will be found in other Mexican caves. Other millipeds from Mexican caves have been described by R. V. Chamberlin (1942).I am indebted to the members of the Texas Speleological Survey for the specimen from which this species was described.

Arnhem Land

We present descriptions of 28 new species of Amphisopidae from Arnhem Land and Kakadu National Park of Australia’s Northern Territory. We identified five additional species that are not yet fully characterized and are not provided with formal species recognition. This is the first taxonomic treatment highlighting the high species richness within the Phreatoicidea that occur in Australia and likely elsewhere. We document each species fully with scanning electron and light micrographic images, diagnoses, detailed descriptions, keys to identification and justification of each species using parsimony analysis of their morphological and genetic characters. The distributional data show that all species, except for one, have microendemic distributions, with some sibling species occurring within a few kilometers of each other. Because of the age of this group of species, they appear to have spread throughout the region of the Arnhem sandstone plateau and then back-colonized the same habitats so that as many as three morphologically and genetically distinct species may co-occur syntopically. Our research has uncovered a new genus-level taxon of the family Amphisopidae, Kakadubeh gen. nov. This new genus is unlike Eophreatoicus, not only in its general appearance, but also in having an inferred reproductive strategy different from most of the other members of the family. While Eophreatoicus species have males that are much larger than the females and practice precopula, a form of pre-insemination mate guarding, males of the new species, Kakadubeh rangemyahwurd sp. nov., are much smaller than females. In addition, males of this species have a fourth walking leg that is not specialized for holding females, suggesting that they have a reproductive strategy that does not involve precopula of the form seen in Eophreatoicus and Eremisopus Wilson & Keable, 2002a. Most of our research has been undertaken in Kakadu National Park, although recent collections have been made in Arnhem Land, yielding additional distinctive species. Given the size of unexplored territory around the Arnhem Plateau and the geographic frequency of discovering new species, we predict that the diversity of this group in the Northern Territory may be many more than the ~35 species described here. At this time, these microendemic isopods appear to be unthreatened by human activities, largely owing to the environmental protection afforded by Kakadu National Park and Arnhem Land, and their cryptic habits during the dry season. Because they are dependent on small springs of permanent groundwater, future changes in hydrology owing to water use and climate change, as well as invasive introduced species, may present risks to populations and species.

Most Japanese records and descriptions of the family Lumbriculidae are from the work of H. Yamaguchi, who described 6 endemic species and one genus, in addition to reporting the cosmopolitan Lumbriculus variegatus (Müller, 1774). Yamaguchi's work focused largely on the northern island of Hokkaido; since then, only one new Japanese lumbriculid genus and species has been described, also from Hokkaido. Recent collections from Honshu Island include several species not recorded in earlier literature, and here we report 4 new species of Lumbriculidae, plus a range extension of the Korean Lamprortus orientalis Rodriguez, 1994. Of the new species, only Styloscolex (Styloscolex) tazawaensis can be confidently assigned to an accepted genus using current morphological diagnoses. Styloscolex (Neoscolex) tatsukoae n. sp. is provisionally assigned to that Asian genus and subgenus based on the prosoporous male duct, spermathecae in the preatrial segment, and penial sheath—despite differing from congeners in having a single, median atrium in X, and single spermatheca in IX. Two additional species are here attributed to a new genus, Honshudrilus, which is distinguished by a combination of characters: spermathecae 2 or more segments anterior to the male pores, non-functional anterior male ducts (with loss of anterior testes), elongate-petiolate atria, penes formed by extruding the atrial duct lining, and spermathecal ducts with vestibules.

A New Species

A new species of microhylid frog of the genus Gastrophrynoides is described from Gunung Besar Hantu, in the state of Negeri Sembilan, adding a new generic record to the family Microhylidae of Peninsular Malaysia and an additional species to the previously monotypic genus Gastrophrynoides. This new species can be distinguished from its only congener, G. borneensis by having an immaculate, grayish brown dorsum (instead of a spotted one); a longer snout (2.6–3.0 vs. 2.0–2.5 times diameter of eye); and a single, large, oval outer metacarpal tubercle beneath the hand (instead of smaller, paired, rectangular outer metacarpal tubercles in G. borneensis).

Four additional species of quill mites of the family Syringophilidae Lavoipierre have now been recorded in England. This includes one new species, Bubophilus aluconis sp. nov., which parasitizes the tawny owl Strix aluco (Strigiformes: Strigidae). It differs from other species of this genus, B. ascalaphus Philips et Norton, 1978 and B. asiobius Skoracki et Bochkov, 2002 by the number of chambers in transverse branch of the peritremes (2-3), the length ratio of setae vi and ve (1:1.6-2), and the lengths of the stylophore and aggenital setae ag1 (180 and 135-145, respectively).

Dental Ontogeny

An exceptionally well-preserved silicified bivalve from the Upper Permian of Texas is described and assigned to a new genus and species,Cassiavellia galtarae, placed in the family Bakevelliidae. The species represents one of the earliest and best characterized unequivocal occurrences of the multivincular ligament in the superfamily Pterioidea. The silicified material provides a wealth of information on the morphology of inadequately known Paleozoic pterioideans, including hitherto undescribed aspects of the larval shell, auricular sulcus, muscle scars, and dental ontogeny. The discovery of the condyle-fossa complex on the anteroventral shell margin, a feature previously undescibed in Bivalvia, raises the question of the homology and taxonomic significance of the problematic subumbonal ridge-like structures in Pterioidea. In life,C. galtaraewas probably an epifaunal right-pleurothetic bivalve, byssally attached to hard or raised flexible substrata. In addition toC. galtarae, another new species,C. nadkevnae, is placed inCassiavellia.

Frame Construction

Phragmactis grayaeSpencer andSwataria derstlerinew genus new species are early (Ordovician) asterozoans (Echinodermata) that comprise the Phragmactinidae. Asterozoans are complexly varied, but as is true for other echinoderms, ambulacral construction is critical to interpretation. Phragmactinids share plesiomorphic aspects of ambulacral form and articulation with basal somasteroids and stenuroids whereas the apomorphic ambulacral expressions of asteroids and ophiuroids are lacking. Phragmactinids, like asteroids and ophiuroids, have only one virgal-series ossicle associated with each ambulacral, unlike the multiple ossicles of somasteroids and stenuroids. Virgal morphology of phragmactinids is reminiscent of expressions in somasteroids and stenuroids. Aspects of phragmactinid mouth frame construction are apomorphic. Morphologies of other ossicular series are similarly varied, and as a result, the family cannot be easily fitted into a recently proposed class-level taxonomy of early asterozoans; it is left in open nomenclature. Phragmactinid morphology does not indicate behavior significantly different from that of other early asterozaons. Asterozoan diversity suggests an early period of rapid evolutionary radiation.
