Taxonomy of the genus Tantunema Siddiqi, 1982 (Dorylaimida: Tylencholaimidae) with description of one new and two known species

One new and two known species of the genus Tantunema Siddiqi, 1982 are described and illustrated. Tantunema indicum sp. nov. is characterized by having a small body (length 0.32–0.45 mm); lip region cap-like, set off by slight constriction; odontostyle 6–7 µm and odontophore 8–10 µm long; pharyngeal expansion gradual, expanded part occupying about 35–41% of total neck length, lumen of posterior expanded part widened and thickened; female genital system mono-opisthodelphic, anterior genital branch absent; tail short, hemispheroid, 0.8–1.1 anal body diameter long. Tantunema pakistanense (Timm, 1964) comb. nov. (=Tylencholaimus pakistanensis Timm, 1964) and Tantunema intermedium (Peña-Santiago and Coomans, 1996) Andrássy, 2009 are redescribed. A diagnostic compendium and key to species of the genus is also provided.     

“压舱石”术语义商补

航运史上,空船往往必须加载压舱石,但加载压舱石的并不只有空船,《现代汉语词典》(第7版)“压舱石”释语中的释义成分“空船”宜改为“船只”。船用固体压舱物构成一个概念系统,其中“压舱石”和“压载铁(压舱铁)”的术语义在语义特征、使用语境和术语色彩上都有显著差异,“压舱石”释语中的释义成分“铸铁”宜删去。

Taxonomy and genetic variation in the Australian lizards of the genus Pseudemoia (Scincidae: Lygosominae)

This study reviews the taxonomy of the southern Australian scincid lizards previously referred to Leiolopisma entrecasteauxii (Duméril and Bibron, 1839) and L. baudini Greer, 1982; here placed along with L. spenceri and the recently described L. rawlinsoni in the genus Pseudemoia. Electrophoretic, karyotypic and morphological data show that populations assigned to P. entrecasteauxii belong to three species. The name Pseudemoia entrecasteauxii is restricted here to a morphologically variable species which occurs in woodlands, forests and heathlands from the Blue Mountains, NSW, through the southeastern mainland, Bass Strait islands and Tasmania, to the islands of Spencer Gulf, SA. Populations designated as L. entrecasteauxii Form B by recent authors are mostly referrable to P. entrecasteauxii (s.s.). Pseudemoia pagenstecheri (Lindholm, 1901) is resurrected to apply to strongly striped populations disjunctly distributed in open grassland habitats from Tasmania, south-central Victoria, the southeast Australian highlands, Blue Mountains and New England Tableland. This species largely encompasses those populations referred to by several workers as L. entrecasteauxii Form A. A neotype for Lygosoma (Liolepisma) pagenstecheri is designated. A new species, P. cryodroma, is restricted to alpine and subalpine habitats on the high plains of Victoria. Pseudemoia cryodroma may have had a hybrid origin from P. entrecasteauxii and P. pagenstecheri. Pseudemoia baudini, hitherto known only from the unique holotype, is redescribed. This species extends eastward along the coast of the Great Australian Bight as far as the Eyre Peninsula, South Australia. A key to the species of Pseudemoia is provided.     

New species of Marionina (Oligochaeta: Enchytraeidae) from a wave-exposed rocky shore in SE Ireland

Marionina macgrathi sp. nov. and M. ulstrupae sp. nov. are described from rock crevices, animal mats and algal turf on a wave-exposed rocky shore at Carnsore Point, County Wexford. Both resemble M. appendiculata Nielsen and Christensen, 1959 in having sigmoid setae and lacking a muscular penial bulb, but differ in possessing seminal vesicles and larger sperm funnels. The new species differ from each other in characters of the sperm funnel, spermatheca, coelomocytes and clitellum. They are compared with material of M. appendiculata from three localities in Ireland and two in USA.     

New ascothoracid crustacean endoparasites of Scleractinia

The ascothoracid crustacean genus Petrarca, endoparasites of scleractinian corals, is reviewed and revised. Petrarca bathyactidis, the type-species, is partly redescribed. The range of P. okadai is extended to East Africa. Three new species of Petrarca are described: P. indica in Flabellum deludens from the Indian Ocean near Ceylon; P. morula from Turbinaria sp. in the Banda Sea; P. azorica in Enallopsammia rostrata from the North Atlantic. Zibrowia auriculata gen. et sp. nov. infests Balanophyllia carinata off East Africa, and the same species appears to live in Tubastraea micranthus off East Africa and Dendrophyllia sp. at Réunion and in the Comoros. Unlike other ascothoracids, eggs and larvae are not brooded within the carapace valves, though they may be attached to them externally. Nauplii of P. okadai and Z. auriculata are described; they are generalized with familially distinct features. Adults of both genera have an overall neotenic appearance. They always occur in galls in groups of two or more, suggesting simultaneous infestation. Ahermatypic corals or their close hermatypic relatives seem to be preferred hosts, and Petrarca has a wider geographic and depth range than confamilial genera.
