The genus Ablattaria Reitter, 1884 (Coleoptera: Silphidae: Silphinae) is revised. Four taxa are recognized as valid species: Ablattariaarenaria (Kraatz, 1876), Ablattariacribrata (Ménétries, 1832), Ablattarialaevigata (Fabricius, 1775) and Ablattariasubtriangula Reitter, 1905. Ablattarialaevigatavar.meridionalis Ganglbauer, 1899 is newly treated as a junior subjective synonym of Ablattarialaevigata. Lectotypes are designated for Phosphugaarenaria Kraatz, 1876, Ablattariaarenariavar.punctigera Reitter, 1884, Ablattariaarenariavar.alleoni Portevin, 1926, Silphacribrata Ménétries, 1832, Silphalaevigata Fabricius, 1775, Silphagibba Brullé, 1832, Ablattariagibbavar.costulata Portevin, 1926, Ablattariagibbavar.distinguenda Portevin, 1926, Ablattariagibbavar.punctata Portevin, 1926 and Ablattariasubtriangula Reitter, 1905. The distribution of all taxa is mapped, based on material examined. Geometric morphometric methods were used to evaluate shape variability in Ablattaria. Results indicated sexual dimorphism in all species. Shape inconsistency was found between the sexes of all taxa when tested independently. The first two relative warp axes indicated 65.17% shape variation in males and 65.72% in females. Canonical variate analysis separated the taxa studied. There was minimal overlap between some groups in both sexes. Differences in body shape between populations of Ablattarialaevigata from Central Europe, Italy and Greece + Turkey were also examined. Relative warps implied 58.01% shape variability on both axes in males and 64.78% in females. CVA revealed noticeable overlaps between the groups, although the Italian population demonstrated a higher separation in both sexes.  相似文献

Three new species of the genus Aeschnosoma are briefly described and illustrated. A. pseudoforcipula n. sp. and A. heliophila n. sp., both from the Brazilian Central Plateau are respectively related to the two Amazonian species A. forcipula Hagen in Selys 1871, and A. auripennis Geijskes 1970. A. louissiriusi n. sp. from Northern Brazil is not closely related to any known species. Based on larval and adult derived characters, the genus Aeschnosoma appears closely related to the Australian genus Pentathemis Karsch 1890, and also to the Madagascan genus Libellulosoma Martin 1907. The clade Aeschnosomata nov. is erected to receive the three genera. Some putative plesiomorphies would place this clade sister group of the remaining Corduliidae s.str.  相似文献

We compared the age, movement, and time–activity budgets of male Calopteryx maculata damselflies occupying off-stream tree-fall gaps with those at stream sites within a 10-ha woodland. All males collected at off-stream sites were younger than males collected at stream sites—as indicated by their significantly higher wing transmittance. Thirty-three percent of teneral males marked at off-stream gaps moved to stream sites within 4 days (mean distance = 140 m), while mature males marked at stream sites never left the stream. In contrast to stream site males, off-stream males spent significantly more time capturing prey and never engaged in aggressive interactions with other males. Behavioral differences were not due to variations in the operative body temperature. However, malaise trapping revealed a greater frequency of suitable prey in forest light gaps. Our findings support the idea that teneral male Calopteryx leave their emergence sites along the stream for off-stream light gaps to forage without interference and build the energy reserves necessary to attain and hold streamside territories.  相似文献

The genus Girardia(Tricladida: Dugesiidae) was recorded in China for the first time. A new freshwater turbellarian species, G. sinensis Chen & Wang, sp. nov., is described, which was collected from Xinghu Lake, Zhaoqing, Guangdong Province, China. Observation and analysis of the new species was conducted on morphology, habits, reproduction, histochemistry and molecular phylogenetics. In addition, the results indicated that morphological differences of ACh E+ nerve structure can be used as a distinguishable character for species identification of Dugesiidae.  相似文献

Six clades are inferred from a phylogenetic analysis including 42 species belonging to the Empis (Coptophlebia) hyalea‐group. These clades are named as follows: E. (C.) acris, E. (C.) aspina, E. (C.) atratata, E. (C.) hyalea, E. (C.) jacobsoni and E. (C.) nahaeoensis. The presence of two dorsal more or less developed epandrial projections is considered autapomorphic for the E. (C.) hyalea‐group in addition to two characters previously found to support the monophyly of this group (presence of an unsclerotized zone in the middle of labella and epandrium unpaired). Amongst the cladistically analysed species, 24 are newly described [ E. ( C. ) acris , E. ( C. ) aspina , E. ( C. ) cameronensis , E. ( C. ) duplex , E. ( C. ) incurva , E. ( C. ) inferiseta , E. ( C. ) kuaensis , E. ( C. ) lachaisei , E. ( C. ) lamellalta , E. ( C. ) lata , E. ( C. ) loici , E. ( C. ) longiseta , E. ( C. ) mengyangensis , E. ( C. ) menglunensis , E. ( C. ) missai , E. ( C. ) nimbaensis , E. ( C. ) padangensis , E. ( C. ) parvula , E. ( C. ) projecta , E. ( C. ) pseudonahaeoensis , E. ( C. ) submetallica , E. ( C. ) urumae , E. ( C. ) vitisalutatoris and E. ( C. ) woitapensis ], five are reviewed [E. (C.) hyalea Melander, E. (C.) jacobsoni De Meijere, E. (C.) ostentator Melander, E. (C.) sinensis Melander and E. (C.) thiasotes Melander] and 13 were recently described in two previous papers. Two additional species, E. (C.) abbrevinervis De Meijere and E. (C.) multipennata Melander, are also reviewed but not included in the cladistic analysis since they are only known from the female. A lectotype is designated for E. (C.) jacobsoni. A key is provided to the six clades of the E. (C.) hyalea‐group as well as to species of each clade. A catalogue of the E. (C.) hyalea‐group, including 72 species, is given. The taxonomic status of 25 additional species mainly described by Bezzi and Brunetti, from the Oriental and Australasian regions, is discussed. The E. (C.) hyalea‐group is firstly recorded from the Palaearctic Region and Australia. Finally, the distribution and the habitats of the species compared with their phylogeny suggest a possible relationship between the diversification of the group and forest fragmentations during the Quaternary. © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society, 2005, 145 , 339–391.  相似文献

Revision of the Neotropical genera of the subtribe Anthaxiina Gory & Laporte, 1839 (Coleoptera, Buprestidae, Buprestinae, Anthaxiini). Five new genera are described: Anthaxita gen. n., Charlesina gen. n., Cobosina gen. n., Marikia gen. n. and Sanchezia gen. n. Genus Agrilaxia Kerremans, 1903 is divided into two subgenera: Agrilaxia and Costiptera subgen. n. and the genus Bilyaxia Hołyński, 1989 is divided into three subgenera: Bilyaxia, Paraguayetta subgen. n. and Tomasia subgen. n. One new species is described: Anthaxita peruviana sp. n., and two informal species-groups are suggested within Agrilaxia (Costiptera subgen. n.): Agrilaxia (Costiptera) modesta (Kerremans, 1897) species-group and Agrilaxia (Costiptera) occidentalis (Kerremans, 1900) species-group. Lectotype is designated for Agrilaxia mrazi Obenberger, 1932. A key of all genera/subgenera is provided and all treated taxa are illustrated.  相似文献

The systematic position and phylogenetic relationships of Echium orientale, a rare endemic of the mountains of northern Turkey, were elucidated based on morphological, molecular, and karyological evidence.

Using nuclear and plastid DNA sequences, we found that this species is not included in Echium, but is rather at least as divergent from it as other related lineages, namely the South African Lobostemon and Echiostachys. Pollen characters revealed a strong affinity with Onosma, especially in the non-reticulate ornamentation of the tectum. Fruit morphology is unique in the genera of the Echium ‘alliance' (e.g. Echium, Pontechium, Lobostemon, and Echiostachys), because of the large size and the smooth, glossy nutlet surface as in most species of Onosma. Karyological observations show that this species is diploid with 2n = 12, and differing from both Lobostemon or Echium, where nearly all species have higher numbers (usually 2n = 14 and 2n = 16, respectively). Combined with a ‘megaherb' habit, the weak zygomorphism of the large flowers and a restricted range in the humid mountain forests of the Black Sea region, fruit, pollen and chromosome characters suggest an isolated position for E. orientale in the Echium alliance. We therefore propose its placement in the monotypic Megacaryon, a genus originally described by Boissier, but largely disregarded by later botanists. An original specimen is designated as generic lectotype.  相似文献

Combining a molecular phylogeny and morphological data, we discovered a new species of Osornophryne from the Amazonian slope of the Ecuadorian Andes. Morphologically, the new taxon is distinguished from all others species in Osornophryne by having the Toes IV and V longer than Toes I-III, a short and rounded snout with a small rostral papilla, and conical pustules on flanks. The new species previously was confused with Osornophryne guacamayo. A taxonomic key is provided for all known species of Osornophryne.  相似文献
