AbstractThe family Nemasomatidae is redefined to include onty genera with all sterna secondarily free from pleurotergites. Comments are given on the included genera, viz., Antrokoreana, Basoncopus gen. n. (type-species B. filiformis sp. n.) (Kazakhstan), Dasynemasoma, Thalassisobates, Sinostemmiulus, Nemasoma, and Orinisobates. Isobates coiffaiti Demange, 1961 is synonymized with Thalassisobates littoralis (Silvestri, 1903). Orinisobates is revised and shown to include O. soror sp. n. (Kuril Islands), O. microthylax sp. n. (Kamchatka and Siberia), O. gracilis (Verhoeff, 1933) (NW China), O. sibiricus (Gulicka, 1963) (Altai region, Kazakhstan), O. kasakstanus (Lohmander, 1933) (Kazahkstan), O. nigrior (Chamberlin, 1943) (eastern United States), O. utus (Chamberlin, 1912) (northwestern United States), and O. expressus (Chamberlin, 1941) (northwestern United States and adjacent Canada). Mimolene oregona Chambertin, 1941 and M. sectile Loomis & Schmitt, 1971 are synonymized with O. expressus. A possible case of parthenogenesis in O. microthylax is recorded. Evidence is presented for the following sister-group relationships: Antrokoreana + (Basoncopus + (Dasynemasoma + (Thalassisobates + (Sinostemmiulus + (Orinisobates + Nemasoma))))). The position of Basoncopus is uncertain, and O. soror may belong in a separate genus and constitute the sister-group of Orinisohates + Nemasoma. If soror does belong in Orinisobates, it is the sister-group of all its congeners. The American species of Orinisobates are shown probably to constitute a monophyietic group. The family is suggested to have originated in the eastern Palearctic region, Orinisobates having invaded North America via the Bering Bridge. Doubtful species and species erroneously assoiciated with the Nemasomatidae are listed. The genera Okeanobates and Yosidaiulus are excluded from the family and referred to Okeanobatidae stat. n. in superfamily Blaniuloidea. The genera Trichonemasoma, Telsonemasoma, and Chelojulus are also excluded from the Nemasomatidae and relegated to Julida incertae sedis.

Abstract. The egglaying (4 eggs) of a Testudo horsfieldii (1570g), which lives in a large outdoor enclosure since 1968, was observed. In a special breeding apparatus two hybrids hatched, the two other ones died in the shell. The parent's mating had not been observed. Fertile males of Testudo h. hermanni (7), Testudo horsfieldii (2) and Testudo graeca ibera (1) are living together in the enclosure with female tortoises. An analysis of the phenotype demonstrated the two hatchlings to be hybrids between T. horsfieldii and T. hermanni. The inauguration of a separate genus Agrionemys is critically discussed. Zusammenfassung. Von einer beobachteten Eiablage (4 Eier) einer Testudo horsfieldii (1570g), die seit 1968 in einer grossen Freiland-Anlage lebt, schlüpften in einem speziellen Brutapparat zwei Bastarde, während 2 Embryonen abstarben. Die vorangegangene Paarung konnte nicht beobachtet werden. In der Anlage Ieben fertile ♂♂ von Testudo h. hermanni (7), Testudo horsfieldii (2) und Testudo graeca ibera (1) . Durch Merkmalsanalyse der Bas tarde konnte eine Kreuzung zwischen Testudo horsfieldii und Testudo h. hermanni nachgewiesen werden . Die Berechtigung einer eigenen Gattung Agrionemys fiir die Art h orsfieldii wird kritisch diskutiert.

Okubasca Dworakowska, 1982, formerly treated as a subgenus of Empoasca Walsh, 1862, is elevated to status as a separate genus. Two new species of Okubasca from China are described and illustrated: Okubasca convoluta Yu & Yang sp. nov.; Okubasca paracalvata Yu & Yang sp. nov. Okubasca convoluta is similar to O. okubella in having the aedeagal shaft about as long as the preatrium but differs in having the aedeagus of uniform thickness in lateral view, the anal tube process straight and the face mostly black. Okubasca paracalvata resembles Okubasca calvata in aedeagal shape, but differs in having a lamellar swelling and a small tooth on the dorsal side of the aedeagus, and the vertex anterior margin rounded.

Abstract The life history, morphology, and biology of the immature stages and phylogenetic relationships of Rotunda rotundapex (Miyata & Kishida, 1990) are described and illustrated for the first time. The species is univoltine: eggs hatch in spring (March or April) and the life cycle from egg to adult is completed in about 3 wk, with larvae developing rapidly on young leaves of the host plants, Morus australis and to a lesser extent Broussonetia monoica (Moraceae), and adults emerging in April–May. Eggs are laid in clusters on twigs of the host plant, are covered by scales during female oviposition, and remain in diapause for the remainder of the year (i.e., for 10–11 mo). Larvae (all instars) are unique among the Bombycidae in that they lack a horn on abdominal segment 8. A strongly supported molecular phylogeny based on six genes (5.0 Kbp: COI, EF-1α, RpS5, CAD, GAPDH, and wgl) representing seven genera of Bombycinae from the Old World revealed that Rotunda is a distinct monotypic lineage sister to Bombyx. This phylogenetic position, together with morphological data of the immature stages (egg and larval chaetotaxy), supports the current systematic classification in which the species rotundapex has been placed in a separate genus (Rotunda) from Bombyx in which it was previously classified.

Our present knowledge of the Strongylid parasites of reptiles is based primarily on Dujardin (1845), who refers all the forms along with those of other vertebrates under a common genus Strongylus, and described four species from the reptilian hosts. Since then our knowledge of parasitic fauna has considerably increased, and von Linstow (1878–89) gave an enlarged list under the same genus from reptiles and also a few under the genus Kalicephalus, Later, with improved methods of Nematode study the forms described were revised, and it was found necessary to split the genus Strongylus, and several groups of a diverse character were recognised. The genus Strongylus was thus split up into several genera, and some of them were removed from the family Strongylidæ. The form Strongylus dispar of Dujardin from the Anguis fragilis was removed into a separate genus, Oswaldocruzia and Strongylus auricularis, with its characters in the absence of buccal capsule and the bifid and trifid distal ends of the spicule seemed more closely allied to Trichostrongylidæ Leiper, and was also removed to the genus Oswaldocruzia.

The paper provides a key for identification and a checklist of mycoheterotrophic species of the genus Exacum, representing a well-defined group of achlorophyllous members of Gentianaceae regarded sometimes in the limits of a separate genus Cotylanthera. One novel species, E. zygomorpha, discovered in northern Vietnam, is described and illustrated as new for science. Among other features the discovered species strikingly differs from its congeners in having distinctly zygomorphic flowers.

Chromosome numbers of marsupials vary between 2n = 11 B 10 @ and 2n =24. Most species have 14 or 22 chromosomes. There is no evidence that polyploidy has occurred in marsupial evolution. The Dasyuridae have 12 metacentric autosomes, a small metacentric X-chromosome and a very small Y-chromosome (20% of living species have been studied) and the chromosomes of Myrmecobius fasciatus are typically like those of other Dasyuridae. The Peramelidae (30% of species have been studied) have chromosomes like the Dasyuridae except that X- and Y-chromosomes are much larger. The occurrence of similar chromosome numbers in Dasyuridae and Peramelidae is not necessarily evidence of affinity. The chromosomes of the Phascolomidae are similar in number and morphology to those of the Peramelidae and the resemblances are, almost certainly, due to parallel evolution. The chromosomes of Phascolarctos are unlike those of any of the Phalangeridae and this genus might be just as easily grouped with the Phascolomidae. The Phalangeridae have considerable chromosomal heterogeneity but less than 20% of species have been studied. Two species of Cercaertus have 12 metacentric autosomes and small sex chromosomes like all members of the Dasyuridae. This suggests that the primitive phalangers may have retained the chromosome number and morphology of possible dasyurid ancestors but the resemblances may be due to parallel evolution of similar chromosome number and morphology in separate groups. The chromosomes have been studied in more than 50% of Macropodinae. Cytological evidence suggests that Thylogale (3 species studied), Petrogale (2 species studied), and probably Lagorchestes (1 species studied), all with 22 chromosomes, are a related group. Onychogalea unguifer, with 20 chromosomes, may be derived from this group. There is no justification for the placing of Thylogale billardierii in the genus Protemnodon. Lagostrophus fasciatus has 2n = 24 and its placement in a monotypic genus is justified. Macropus major and all species of Protentnodon, except P. bicolor, are a related group with 16 chromosomes. M. robustus is possibly included in this group. M. rufus has 20 chromosomes and should perhaps be placed in the separate genus Megaleia. P. bicolor, with 11 chromosomes in the male and 10 in the female, differs from all other species of Protemnodon and this genus, as at present constituted, may be diphyletic. The relationships of P. bicolor are unknown. Setonix brachyurus has 22, mostly metacentric, chromosomes and its affinities are at present unknown. Three species of Bettongia (Potoroinae) have 22 chromosomes which are mostly metacentric. Hypsiprymnodon moschatus has 22 chromosomes which are mostly acrocentric. Both genera are very different cytologically from Potorous tridactylus.

The rust species Coleopuccinia sinensis was collected during an investigation of rust fungi in Tibet, a region in south-western China. Through morphological examination, we clarified that C. kunmingensis is a synonym of C. sinensis. Phylogenetic analyses using the combined loci of the internal transcribed spacers (ITS) and the partial large subunit (LSU) rRNA gene revealed that Coleopuccinia should be treated as a separate genus from Gymnosporangium.

AbstractThe lichen family Umbilicariaceae is accepted by most lichenologists as consisting of two genera, Lasallia and Umbilicaria. The monophyly of these two genera was examined by phylogenetic analyses of nucleotide sequences of ITS 1 and ITS2 rDNA. Sequences of these regions from three Lasallia and 17 Umbilicaria species were aligned to those of seven representatives of the outgroup taxa including Eurotiales, Onygenales and Caliciales (Mycocaliciaceae) and subjected to maximum parsimony, maximum likelihood and neighbour-joining analyses. The resulting phylogenetic hypotheses supported the monophyly of the representative species of Lasallia. However, the species of Umbilicaria did not form a monophyletic sistergroup to Lasallia due to the basal placement of other Umbilicaria species in some analyses. Based on these analyses, if Lasallia is recognized as a separate genus then Umbilicaria appears to be paraphyletic. Although further taxon sampling is required to resolve the monophyly of Umbilicaria, for the present we recommend retaining the current treatment of Lasallia as separate from Umbilicaria.

The anatomy of pericarp of the mature fruit of Cardiocrinum cordatum (Thunb.) Makino was investigated.It was revealed, that the fruit of Cardiocrinum is a superior loculicidal capsule. The anatomy of its pericarp allow totreat the fruit as a transitional type of capsules between Lilium-type (the endocarp is lignified) and Galanthus-type (nolignification occurs in any zone of the pericarp). The peculiarities of pricarp structure of Cardiocrinum supports itstreatmend as a separate genus of the Liliaceae family.
