Pentaphyllus reibnitzi sp. nov. from Cyprus is described, representing the fourth species of Pentaphyllus from the western Palaearctic Region. All four species from this area are figured, a key for their identification and selected faunistic data are given. Two species have a wider distribution in the western Palaearctic Region, and two are restricted to limited areas in Azerbaijan or Cyprus, respectively. The type specimens of the new species were found in polypores, collected from a dead tree of Ficus carica in an extensively cultivated garden near seashore. Lectotype of Pentaphyllus nitidulus Reitter, 1884 is designated.
Leaf hair types in Polish selected taxa from Potentilla subsect. Collinae Juz., i.e. P. collina Wibel s.str., P. silesiaca Uechtr. P. thyrsiflora Hillsen ex Zimmeter, P. wimanniana Gilnther and Schummel, P. leucopolitana P.J. Milller and P. leucopolitana P.J. Milller x P. incana P. Graebner were studied. A total of five unicellular hair types could be distinguished, based on the structure of the hair: straight, involuted, crispate, curved and stellate. The occurrence of involuted, curved and stellate hairs was observed for the first time for the majority of investigated taxa. There is a variation in density, position, as well as in the number of arms of stellate hairs. Although they are difficult to see without a stereo microscope, these differences seem to be systematically important. The study of hair types on surfaces of leaves supports the opinion that P. collina s.lato is a hybrid between P. argentea L. s.la-to, P. tabernaemontani Ascherson and P. incana P. Gaertner. Hairs form consistent characters which are highly suited for systematic purposes. The key to Polish taxa based on leaf hair types is given as well.
Two new species of Sogana Matsumura, 1914: S. condaoana sp. nov. and S. cucphuongana sp. nov., both from Vietnam are described and illustrated. The species are compared with S. longiceps Fennah, 1978. A key to the species from Vietnam and a distribution map are provided. The genus now contains 10 species. The records of S. longiceps from China are considered as erroneous.
Faunistic, distributional, and taxonomic data for the genus Phalangium Linnaeus, 1758 from the Caucasus are presented. Eight species of the genus have been found in the region. Two new species: P. mcheidzeae from Georgia and P. gorbunovi from Volgograd region, Kalmikiya and Krasnodar region are described, the other six species of the area are P. opilio, P. punctipes, P. armatum, P. staregai, P. bakuense and P. armenicum. Each of them is illustrated, their main diagnostic features are summarized and the occurrence of each species is presented. A key to the species of Phalangium of the region is provided.
The species of the tenebrionid genus Stomylus Fåhraeus, 1870 (type species Stomylus bicolor Fåhraeus, 1870) (syn. Pselaphidion Gebien, 1920) within the tribe Diaperini are revised. Seven species are recognized as valid, distributed exclusively in Africa south of the Sahara and lacking in Madagascar. The diagnostic characters are figured (also by Scanning Electron Microscope), new distributional data are given and an identification key is compiled. New synonyms: Stomylus apicatus (Gebien, 1910) = Stomylus trituberculatus (Pic, 1926) syn. nov.; Stomylus nigronitens Gebien, 1920 = Stomylus loebli Ardoin, 1980 syn. nov.; Stomylus schroederi (Gebien, 1904) = Stomylus schroederi ssp. bimaculatus Ardoin, 1969 syn. nov. New combination: Diaclina gracilis ( Fåhraeus, 1870) comb. nov. from Stomylus.
The paper provides data on a new antropophyte species - Typha laxmannii Lepech. which spreads throughout Poland as a hemiagriophyte. Its present distribution in Poland is given on a cartogramme map in a 10×10 km square grid and its geographic element, population numbers and notes on habitats are provided. An identification key to 5 species of the Typha genus, two native, one new which is the topic of this paper, and two which can be expected to be discovered in Poland.
The opecoelid species Macvicaria jagannathi (Gupta et Singh, 1985) Bijukumar, 1997 (new syn. Plagioporus deeghaensis Gupta et Gupta, 1988) and Neolebouria lineatus Aken’Ova et Cribb, 2001 are redescribed from Nemipterus furcosus, from the waters off New Caledonia. Provisional keys to the genera Macvicaria Gibson et Bray, 1982 and Neolebouria Gibson, 1976 are presented. The following new combinations are made: Macvicaria yamagutii (Gupta et Ahmad, 1977), M. puriensis (Gupta et Govind, 1984) and M. chilkai (Gupta et Govind, 1984).
The paper introduces Lamprodila mirifica (Mulsant, 1855) as a beetle new for the Polish fauna. This is a monophagous species whose larvae develop under bark of branches and trunks of elms, preferably well insolated. It was recently found on the Wiekopolsko-Kujawska Lowland, in Krajkowo near Poznań – hitherto the only locality in Poland and the northernmost in Europe. A key to the identification of Polish species of Lamprodila Motschulsky, 1860 is provided.
Accurate and efficient identification of bat (Microchiroptera) echolocation calls has been hampered by poor knowledge of the intraspecific variability in calls (including regional variation), a lack of call parameters for use in separating species and the amount of time required to manually identify individual calls or call sequences. We constructed and tested automated bat call identification keys for three regions in New South Wales, Australia, using over 4,000 reference calls in ≈300 call sequences per region. We used the program AnaScheme to extract time, frequency and shape parameters from calls recorded with the Anabat system. Classification trees were built to separate species using these parameters and provided the decision rules for construction of the keys. An ‘Unknown’ category was included in the keys for sequences that could not be confidently identified to species. The reliability of the keys was tested automatically with AnaScheme, using independent sets of reference call sequences, and keys were refined before further testing on additional test sequences. Regional keys contained 18–19 species or included species groups. We report rates of sequence misidentification (accuracy) and correct identification (detection) relative to all sequences (including ‘unknowns’) used to test each version of a key. Refined versions of the keys were accurate, with total misidentification rates of 0.5–5.3% for the three regions. Additionally, total correct identifications for regions were 56–75% (> 50% for most species), an overall high rate of detection. When ‘unknowns’ were ignored, as is common in many published studies, correct identification for regions increased to 91–99%, rates which compare favourably to the most successful classifiers tested to date. The future use of AnaScheme for automated bat call identification is promising, especially for the large-scale temporal and spatial acoustic sampling to which Anabat is particularly suited.
Genera of Trombidiidae and Podothrombiidae of the World are reviewed and their diagnoses verified based on the type material and non-type specimens originating from samples collected in different zoogeographical regions. Twenty two genera of Trombidiidae and two of Podothrombiidae are recognized. Each generic account is supplemented with a map of hitherto known distribution. A key to the world genera of Trombidiidae and Podothrombiidae is provided and a list of species included in each genus is given. The following six new genera are established within Trombidiidae: Andinothrombium, Andrethrombium, Darjeelingia, Robauxthrombium, Ronaldothrombium, Wohltmannella. Six new trombidiid species are described: Andinothrombium elatum, Darjeelingia longipes, Dolichothrombium azerbaijanicum, D. tenerifensis, Robauxthrombium andinum, Ronaldothrombium parametae. New generic synonyms are proposed for Allothrombium Berlese, 1903 (=Corethrothrombium Oudemans, 1928, =Mongolothrombium Feider, 1979), Mesothrombium Hirst, 1926 (=Austrothrombium Womersley, 1934) and Trombidium Fabricius, 1775 (=Kaszabothrombium Feider, 1973). Verified diagnoses of monotypie genera Calctrombidium Haitlinger, 2003 and Oskootrombium Saboori et al., 2006 are provided. Variathrombium Robaux, 1969 is excluded from Podothrombiidae and transferred to Trombidiidae. Archithrombium Feider, 1955, Emitrombidium Lombardini, 1949 and Phyllotrombidium Cooreman, 1946 are treated as nomina dubia. Porttrombidium Haitlinger, 2000 is excluded from Trombidiidae and regarded as more closely related to Microtrombidiidae and Neothrombiidae. The following new specific synonyms are proposed: Acarus tinctorius Linnaeus, 1767 (=Trombidium tinctorium var. brevipilum Berlese, 1910), Trombidium megalochirum Berlese, 1910 (= Caenothrombium coccineum André, 1947). The following new combinations are created within Trombidiidae: Allothrombium christopheanum (Kramer, 1897), Allothrombium laticoxum (Feider, 1973), Allothrombium pectinifer (Oudemans, 1926), Allothrombium vandermeermohri (Oudemans, 1929), Andrethrombium crassicomum (Berlese, 1910), Andrethrombium delamarei (André, 1962), Azaritrombium telletxeae (Goldarazena et al., 2000), Caenothrombium corpulentum (Berlese, 1910), Caenothrombium dammermani (Vitzthum, 1926), Clinotrombium southcotti (Fain, 1991), Mesothrombium mullewaense (Southcott, 1986), Mesothrombium porongorense (Southcott, 1986), Mesothrombium scaurum (Southcott, 1986), Mesothrombium ursinum (Berlese, 1910), Paratrombium crassipalpe (Trägårdh, 1904), Paratrombium colhuanum (Vitzthum, 1933), Paratrombium monoeciportuense (André, 1928), Paratrombium pedioculatum (André, 1927), Paratrombium quadrimaculatum (Berlese, 1912), Paratrombium raeticum (Schweizer et Bader, 1963), Paratrombium superbum (Banks, 1910), Paratrombium tarsale (Berlese, 1916), Paratrombium trispilum (Berlese, 1916), Robauxthrombium chiliense (Robaux, 1969), Robauxthrombium eupectum (Leonardi, 1901), Robauxthrombium unisetum (Robaux, 1969), Ronaldothrombium bellator (Southcott, 1986), Ronaldothrombium dumosum (Southcott, 1986), Ronaldothrombium watanabei (Shiba, 1976), Trombidium aratrorum (Feider, 1973), Wohltmannella cypriense (Robaux, 1964), Wohltmannella dobrogiacum (Feider, 1950), Wohltmannella vannieri (Robaux, 1967), and - within Podothrombiidae: Kurilothrombium shibai (Gabryś, 1988). An adult specimen of Dinothrombium tinctorium (Linnaeus, 1767) is selected as neotype. Lectotypes are designated for Allothrombium crassicomum Berlese, 1910 (now Andrethrombium crassicomum), Allothrombium delamarei André, 1962 (now Andrethrombium delamarei), Allothrombium gracile Berlese, 1910, Allothrombium metae Boshell et Kerr, 1942, Allothrombium pergrande Berlese, 1903, Caenothrombium unisetum Robaux, 1969 (now Robauxthrombium unisetum), Dinothrombium (Dolichothrombium) alpinum Schweizer, 1951 (now Dolichothrombium alpinum), Dolichothrombium fournieri Robaux, 1967, Dinothrombium (Dolichothrombium) grandjeani André, 1954 (now Dolichothrombium grandjeani), Podothrombium subnudum Berlese, 1910, Trombidium insulare Berlese, 1910 (now Paratrombium insulare), Sericothrombium monoeciportuense André, 1928 (now Paratrombium monoeciportuense), Trombidium quadrimaculatum Berlese, 1912 (now Paratrombium quadrimaculatum), Trombidium tarsale Berlese, 1916 (now Paratrombium tarsale). Sericothrombium holosericeum var. brevipapillosa André, 1924, earlier synonymized with Trombidium holosericeum (L.), is restored to specific status - Trombidium brevipapillosa (André, 1924). Andrethrombium delamarei (André, 1962), Dinothrombium tinctorium (Linnaeus, 1767) and Dinothrombium oparbellae (André, 1949) are redescribed. An attempt at reconstructing relationships among the genera has been made. The maximum parsimony and neighbour joining analysis considered 129 characters of 62 specific level taxa (including four taxa assigned to the outgroup) known from different life stages. The monophyly of most taxa has been confirmed and the scope of hitherto distinguished subfamilies of Trombidiidae has been verified. The following new subfamilies are proposed within Trombidiidae: Dolichothrombiinae - with Dolichothrombium Feider, 1945 and Paratrombiinae - comprising the genera Paratrombium Bruyant, 1910 and Pollicotrombium Southcott, 1986.
