A New Species

Within recent years a considerable amount of work has been done on the Myxosporidia, especially, as pointed out by Kudo (1919), in North America, Asia, and to a lesser degree in Japan (Fugita, 1912, 1913, 1925). Few investigations, however, have been carried out in Australia, and consequently very little is known concerning the distribution of the group in this country. There appear to be as yet only two contributions to the subject, papers by T. Harvey Johnston and M. J. Bancroft (1918, 1919). As far as can be ascertained, my paper is the first report concerning Myxosporidia from fishes of Southern Australian waters, and contains the first record of a species of Chloromyxum from Australia.

A New Species

Rhodocollybia utrorensis sp. nov. is described from the Utror valley, Pakistan. It is characterized by a dull brown pileus with a low umbo and inrolled margin, adnate lamellae with wavy margin, presence of pleurocystidia and inamyloid basidiospores. Both morpho-anatomical features and phylogenetic analysis based on ITS nrDNA sequence indicate Rhodocollybia utrorensis is a new species. This is the first report of the genus Rhodocollybia from Pakistan.

AbstractThe adult, pupa, and final-instar larva of Trichothaumalea elakalensis sp.nov. (Diptera: Thaumaleidae) are described and illustrated. This is the first record of this genus from eastern North America and first description of the immature stages. In addition, reinterpretation of the homologies of the male terminalia and preliminary observations on the male reproductive system of Thaumaleidae are presented and the phylogenetic implications upon the monophyly of the Chironomoidea are discussed.

A New Species

A new species of the sphenacodontid synapsid Dimetrodon, D. teutonis, is described on the basis of a single, adult specimen consisting of a large portion of the presacral vertebral column. The holotype was collected from the Lower Permian Tambach Formation, lowermost formational unit of the Upper Rotliegend, of the Bromacker quarry locality in the midregion of the Thuringian Forest near Gotha, central Germany. This is the first record of the genus outside of North America and, therefore, provides not only additional biological evidence of a continuous Euramerican landmass during the Early Permian, but also the absence of any major physical or biological barrier to faunal interchange of terrestrial vertebrates. An estimated weight of 14 kg for D. teutonis is half that of the smallest, previously recognized species, D. natalis. Sphenacodontid phylogeny indicates that the diminutive size of D. teutonis represents an autapomorphy and is in general accord with the absence of large-sized, basal synapsid predators at this truly terrestrial upland locality. It is speculated that the diminutive size of D. teutonis was probably an adaptation to a truly terrestrial, relatively uplands existence like that represented by the Bromacker locality. Here it subsisted on small vertebrates (and possibly large invertebrates) of the Bromacker assemblage, in which the dominant members in both size and abundance were herbivorous diadectids, and it was unlikely to encounter large predators.

A new species of teuthid squid, Teudopsis cadominensis, is described from the Toarcian (Lower Jurassic) Poker Chip Shale of the Fernie Formation in central-western Alberta. Fossil squids are rare in the Mesozoic of North America; this species is the first record of the family Palaeololiginidae in North America and the first member of the suborder Mesoteuthina in the Jurassic of North America.

A New Species

A new species of the family Anaxyelidae (Eosyntexis parva n. sp.) is described. This is the first record of the family from Lower Cretaceous Spanish amber. The specimen is mostly well preserved, except for dorsally. This makes it possible to identify several important details rarely or never observed in compression fossils. Eosyntexis spp. and the closely related genus Cretosyntexis are confined to the Eurasian Lower Cretaceous, whereas the extant monotypic genus Syntexis is restricted to western North America. The morphology of this new species suggests xylophagous habitus, and its relation with Syntexis libocedrii implies a possible relationship with burned wood, apparently a frequently available resource in northern Spanish forests of the Lower Cretaceous.
