The genus Xystodesmus Cook, 1895 (most closely related to Riukiaria Attems, 1938) is retained as a taxon of xystodesmine millipedes with relatively small body length (25-35 mm), male gonopods more complicated than just forceps-like conformation, and live colouration grey-brown tergites red, orange, or yellow paranotal spots. Seven new species the (Xystodesmusfasciatus sp. nov., X.keramae X.kumamotoensis X.kumeensis X.parvus X.rebekae X.sesokoensis nov.) are described from islands Kyushu,...
Abstract The rate of heat exchange with the environment is obvious importance in determining time budget behavioural thermoregulation ectotherms. In small reptiles, heating depends mainly on their physical characteristics. We analysed effect body size, and possible joint effects originating from shape colour differences three small-bodied (0.15-20 g) sympatric lizard species. Heating was strongly influenced by while no two other factors were detected. found that increase decreasing size...
The genus Oxidus Cook, 1911 is revised to contain five species, O. avia (Verhoeff, 1937), gigas (Attems, 1953), gracilis (C.L. Koch, 1847), riukiaria 1940), and “species inquirenda” obtusus (Takakuwa, 1942). A cosmopolitan gracilis, widely found in temperate sub-tropical regions over the world, but other species have limited distribution restricted regions, e.g., northern Vietnam, Ryukyu Islands (Japan). Four riukiaria, gigas, are confirmed as different from each gonopod characters,...
Abstract During a continuous population study of Vipera ursinii rakosiensis, 79 specimens were measured in the field, between 1993 and 1997. Body length body mass six juveniles compared to those 43 more which kept during their first winter terraria. Significant differences found favour captivity, whereas comparison with earlier data from 1953 showed strong decline juvenile mass. Based on size, three age classes could be distinguished population. The annual activity reproductive cycle...
Three main types of asymmetry in bilateral characters were early separated (Van Valen, 1962).Directional a character means consistent bias towards always the same side as opposed to other, whereas antisymmetry is pair where enlarged occurs by chance.Both directional and result from normal development.Fluctuating (FA), that nondirectional deviation perfect symmetry, when development perturbed (Palmer Strobeck, 1986;Leary Allendorf, 1989).These perturbances can include habitat degradation...
Abstract The Caspian whipsnake (Squamata: Serpentes: Dolichophis caspius) reaches its northwestern distribution limit in Hungary where it is the single representative of genus. Recently, several new localities species were discovered Hungary. Focusing on these edge populations and other ones western parts distribution, a phylogeographic study based cytochrome b sequences was carried out. Thereby, clear mitochondrial divergence observed Europe, with eastern haplotype groups found by analysing...
A Balkan checklist of the millipede genus Megaphyllum Verhoeff, 1894 has been compiled on basis literature data, new collections, and reexamination type non-type material. Forty-seven species subspecies are represented in peninsula, including four to science: M. chiosense Lazanyi & Korsos sp. n. from Chios Island, cygniforme East Macedonia, danyii digitatum both Peloponnese, Greece. The following synonymies established: monticola (Verhoeff, 1898) syn. carniolense 1897); latesquamosum...
Abstract Understanding the factors that determine abundance of populations is key importance in conservation biology, ecology, and biogeography. For grassland‐associated species, such as Hungarian meadow viper ( Vipera ursinii rakosiensis ), habitat management particularly important. We aimed to study effects three most common types grassland (grazing, mowing, mowing + grazing) on reptile species habitats Kiskunság National Park, Hungary. surveyed grasslands repeatedly n = 15 occasions) for...
The single New Zealand genus, Eumastigonus Chamberlin, 1920, of the millipede family Iulomorphidae (Spirostreptida: Epinannolenidea) is reviewed, diagnosed, and its morphological characters are discussed. Redescription generotype E. kaorinus further records distinctior hemmingseni Mauriès, 1983, descriptions two new species: hallelujah sp. n. waitahae given.
The epinannolenidean diplopod species Zinagon chilensis (Silvestri, 1903) is redescribed based on recently collected ma-terial from Chile, as well the re-examination of type specimens both Iulomorpha Silvestri, 1903, andZinagon osorno Chamberlin, 1957. latter here designated a junior subjective synonym. A list thefamily Iulomorphidae provided, including 15 genera occurring in Southern Hemisphere, i.e. South America, Africa, Australia, and New Zealand.
Ablepharus kitaibelii fitzingeri is the northernmost subspecies of snake-eyed skink (the only representative genus in Europe), and an endemic species Carpathian Basin. Despite its unique status Hungarian herpetofauna strict protection, no recent summary has been provided on distribution country. In last attempt, Dely (1978) presented 40 localities subspecies. Here we give updated (100 localities), based records from literature, collection Natural History Museum (HNHM), field surveys made by...
In the framework of botanical and zoological expeditions Hun - garian Natural History Museum to Balkans, a specimen Vipera ursinii graeca was observed in southern Nemercke Mountains Albania. It is first record subspecies outside Greece, but zoogeographically it belongs northern Pin
The East Asian millipede genus Riukiupeltis Verhoeff, 1939 is revised, and restricted to a single species, jamashinai 1939. Examination of the type specimens freshly collected material from Ryukyu Archipelago Vietnam show that both subsequently allocated uenoi Murakami, 1975, falcatus (originally Haplogonosoma falcatum Attems, 1953, reallocated by Jeekel 1968), do not belong this genus; moreover, they are even congeneric with each other. According our morphological observations, including...
On the basis of male and female genitalia nonsexual morphology, revision Megaphyllum projectum Verhoeff, 1894 its five nominal subspecies (M. p. 1894, M. alticolum 1897, deubeli 1899, kochi 1907, dioritanum 1907) has been carried out. The forms proved to be valid subspecies, while other two are synonymised with nominotypical projectum. differences in gonopod from only due positioning under microscope, showed also minor projectum, so it cannot considered as separate subspecies. Female seem...
