The expression of aggression in Megaloptera has received little attention, specifically for the adults of the subfamily Corydalinae. Among the New World species of Corydalinae, it is not known if aggression is triggered and expressed in the same way. Since two genera, Corydalus Latreille, 1802 and Platyneuromus Weele, 1909 have different courtship strategies, the effect of the social environment in the expression of aggression in two species of those genera, Corydalus magnus Contreras-Ramos, 1998 and Platyneuromus soror (Hagen, 1861), is examined here and compared with the known data in Corydalus bidenticulatus Contreras-Ramos, 1998. Our results suggest that the triggering of aggressive behaviours in the three species is similar. The decision of whether or not to fight is affected by their social environment: a male is aggressive against other males only when a female is present. Furthermore, the intensity of aggression does not differ among the three species. The behavioural observations support the idea that the mandibles of Corydalus males are used as weapons in male-male competition and during the courtship, but the post-ocular flanges of P. soror males are not involved in male-male competition (they use their short mandibles to bite). Conversely, data show that such a feature might act as a signal trait for female choice. 相似文献

The Clytra subfasciata species group is proposed, to comprise Clytra subfasciata Lacordaire, 1848, C. hajeki Medvedev &; Kantner, 2002 and C. kadleci sp. n. (Yemen). The species of the group are characterised by the peculiar shape of the aedeagus, with a dorsal plate separated from the rest of aedeagus by a deep narrow slit. Colour photographs of habitus and drawings of genitalia are provided for all three species.http://www.zoobank.org/urn:lsid:zoobank.org:pub:F6706A76-CD49-4A5A-A109-A6E6C23514A5 相似文献

Cneocnemis arabica sp. n. is described from western Saudi Arabia. The type locality lies disjunct from the large conjunct area of the Asian congeners, probably due to the lack of suitable habitats (?trees) in central and eastern Arabia. C. angustula (Fairmaire, 1893) comb. n. from Indochina is transferred from Uloma to Cneocnemis. Additionally, the first records of Cenoscelis pulla (Erichson, 1843) from Saudi Arabia are listed. The species of Cenoscelis seem at least not to be restricted to arboreal habitats. 相似文献

Two new sites with mammalian footprints in the early Oligocene of southeastern France are described here. They represent one of the best preserved and more numerous record of tracks and trackways in the world with more than 320 ichnites. Many of those are arranged in trackways and sometimes show pes-manus impressions, a quite rare feature in mammalian ichnology. The ichnotaxonomic study indicates the presence of perissodactyls tracks referred to as Rhinoceripeda voconcense (Demathieu et al., 1984), artiodactyls footprints referred to as Megapecoripeda velox (Demathieu et al., 1984) and a carnivore footprint referred to as Bestiopeda sp. Vialov (1966). They can be attributed to early Rhinocerotids, Lophiomerycids and/or Entelodonts and Mustelid-like carnivore, respectively. This study also aims at homogenizing the ichnotaxonomy used for mammal tracks where several genera were erected without a full review of the literature. All this taken together reveals a rich mammalian ichnofauna at a time period when no other fossils of mammals are known in the area and represents a good opportunity to provide state-of-the-art concerning the worldwide known sites that yielded mammalian footprints. 相似文献

The larvae of the grooved whirligig beetle Macrogyrus oblongus (Boisduval, 1835) are described and illustrated including detailed morphometric and chaetotaxic analyses of selected structures. Larvae of Macrogyrus Régimbart, 1882 exhibit the characters traditionally recognised as autapomorphies of the Gyrinidae. The first instars bear egg bursters on the parietal, a potential additional autapomorphy. Putative larval autapomorphies of the tribe Dineutini are the presence of additional setae on the mandible, the absence of the seta TR2, and the presence of pore-like additional structures on the ultimate palpomeres. Macrogyrus larvae differ from those of the other known dineutine genera (Andogyrus Ochs, 1924 and Dineutus MacLeay, 1825) in the absence of a neck constriction and in the distal position of the pore LAc. Other useful characters to distinguish genera within Dineutini are the presence or absence of additional setae on the cardo and coxa, and the posterior margin of the lacinia dentate or smooth. 相似文献

The genus Hemimysis (Malacostraca: Mysida: Mysidae) encompasses near-bottom, demersal and cave-dwelling mysids living in the marine, brackish and freshwater habitats around the European coast, from the Caspian Sea to the Scandinavian Peninsula. We conducted cladistic analysis of 52 morphological characters of all nine species and three subspecies of the genus Hemimysis. We also completed a molecular analysis based on three molecular markers of Hemimysis lamornae (Couch, 1856) found in the English Channel, the Mediterranean Sea, and the Black Sea. Both analyses did not support monophyly of Hemimysis lamornae. We thus consider the former subspecies H. lamornae pontica (Czerniavsky, 1882) and H. lamornae mediterranea Bacescu, 1936 as valid species. Analysis of mitochondrial cytochrome oxidase subunit I (COI) sequences of H. pontica shows no significant divergence between mysids living in the marine caves of Crimea and Bulgaria. Morphological trends in Hemimysis are discussed, H. pontica Czerniavsky, 1882 is redescribed, and a new key to all 11 species of the genus is given. 相似文献

We describe a new species of Micragasma J. Sahlberg, 1900 (Coleoptera, Hydraenidae), which is here treated as a subgenus of Ochthebius Leach, 1815. The new species, O. (Micragasma) minoicus sp. n., was found at the margins of a coastal rockpool in the island of Crete. The species differs from the other two known species of Micragasma in both external and genital characters, but shares with them the presence of small setiferous tubercles on the surface of the head, pronotum and elytra, and a strong medial gibbosity on the head. In some characters, such as the structure and shape of the aedeagus, O. (M.) minoicus sp. n. is similar to other species of the genus Ochthebius, in particular of the subgenus Cobalius Rey, 1886, typical of coastal rockpools.http://zoobank.org/urn:lsid:zoobank.org:act:BCEAE1EE-7C5E-4017-A753-559738221502 相似文献

ABSTRACTThe larval stages of the genus Kempynus Navás, 1912 (probably K. falcatus Navás, 1912 based on the presence of synchronic and sympatric adults) are described for the Neotropical Region for the first time, and the larval stages of Isostenosmylus pulverulentus (Gerstaecker, 1893) are redescribed. The external morphology of third-instar larvae of both species and their habitats are described and compared. Kempynus sp. is a water-dependent species and can be considered semi-aquatic, whereas I. pulverulentus larvae are terrestrial and live in undergrowth vegetation. The first key to identification of Neotropical Osmylidae larvae is provided, based on third-instar larvae of both species. 相似文献

This study investigates the diversity and taxonomy of a mainly marine group of species lacking chaetae currently assigned to the genus Marionina. This achaetous group includes four nominal species: M. achaeta (Hagen, 1954), M. achaeta sensu Lasserre, 1964, M. nevisensis Righi & Kanner, 1979 and M. arenaria Healy, 1979. As Lasserre's (1964) M. achaeta appears to be morphologically different from its (then) senior homonym M. achaeta (Hagen, 1954), the replacement name M. nothachaeta nom. nov. is proposed for it. We studied the genetic and morphological diversity of achaetous specimens of Marionina collected in Florida, the Great Barrier Reef, New Caledonia, Sweden, England and the Bahamas. The collection localities are almost all supralittoral and often brackish-water habitats. Parts of the mitochondrial genes 12S, 16S, COI and the nuclear genes 18S, 28S and ITS were analysed to assess the genetic variation and phylogeny of the achaetous Marionina species. The molecular data reveal one monophyletic group of 11 separately evolving lineages, and between these lineages, K2P distances in the barcoding gene COI vary between 5.4 and 25.0%. On a morphological basis, the lineages could be assigned to seven different groups (morphotypes), of which only two could be identified as described nominal taxa: M. nevisensis s. lat. (several lineages) and M. nothachaeta. Since the former taxon appears to be a complex of cryptic species around the world and the original type material no longer exists, a neotype from the Caribbean was designated for M. nevisensis s. str. The remaining achaetous lineages represent five morphologically distinct species that are left unnamed, awaiting finer morphological scrutiny and detailed comparisons with new collections of M. achaeta and M. arenaria. Summing up, the group of achaetous Marionina now seems to contain up to 13 different species, seven of which are yet to be formally described and named. 相似文献

The subfamily Microtypinae Szépligeti, 1908 (Hymenoptera: Braconidae) is recorded for the first time for Egypt. The present study is based on specimens collected from Gebel Elba, Wadi Allaqi, St. Catherine, and Fayoum, as well as specimens deposited in various entomological collections in Egypt. Four species belonging to the genus Microtypus Ratzeburg, 1848 (M. algiricus Szépligeti, 1908; M. desertorum Shestakov, 1932; M. vanharteni van Achterberg, 2010 and M. aegypticus sp. n.) are reported for the first time from Egypt.http://www.zoobank.org/urn:lsid:zoobank.org:pub:022282A1-183F-4E0C-9F88-A53C42735532 相似文献

The oligolectic bee genus Melitta Kirby, 1802 (Melittidae: Melittinae) is recorded from the Arabian Peninsula for the first time, and from Saudi Arabia in particular. A series of females of Melitta schmiedeknechti Friese, 1898 were captured near Jabal al Mashār, Ha’il, Saudi Arabia, representing the first occurrence of this species, previously known across northern Africa and the southern Levant. Brief remarks and a key are provided for the two subspecific forms of M. schmiedeknechti. 相似文献

This contribution reviews the worldwide record of canid and canid-like (creodont and hyaenid) fossil footprints, the taxonomy of this type of footprints, and reports a new record of canid footprints from the late Pleistocene Pehuen Co site of southern Buenos Aires province, Argentina. On the basis of the comparison of proposed ichnogenera and features of modern canid and felid footprints, a set of ichnogeneric and ichnospecific taxobases are proposed. The ichnotaxonomic review includes Bestiopeda Vialov, 1965; Canipeda Panin and Avram, 1962; Felipeda Panin and Avram, 1962; Pehuencoichnum Aramayo and Manera de Bianco, 1987b; Creodontipus Santamaría et al. 1989–1990; Tetrastoibopus Sarjeant and Langston, 1994; and Quiritipes Sarjeant et al. 2002. A key to discriminate these ichnotaxa is also proposed and the diagnosis of Canipeda emended. The new findings of canid footprints from Pehuen Co are indistinguishable from Pehuencoichnum gracilis Aramayo and Manera de Bianco, 1987b, and this ichnospecies is synonymized under Canipeda gracilis (Vialov, 1965). An emended diagnosis for C. gracilis is proposed. The most likely producer of C. gracilis from Pehuen Co is a medium-sized fox similar to the extant representatives of Lycalopex. 相似文献

The Colombian species of the diving beetle genus Liodessus Guignot, 1939 are revised. Liodessus bogotensis Guignot, 1953 is re-described. Three higher altitude species are new to science: Liodessus azufralis sp. n., L. quillacinga sp. n. and L. quimbaya sp. n. We also introduce two new subspecies, L. quillacinga cochaensis ssp. n. and L. quillacinga cumbalis ssp. n. We delineate the species using morphological structures such as male genital structure and beetle size, shape and colour pattern. Mitochondrial cox1 sequence data provided an additional character source. All the new species occur on higher altitudes above 2700 m and were collected in shallow, exposed peatland pools and puddles, mostly in Páramo. Liodessus obscurellus (LeConte, 1852), not yet recorded from Colombia, is included into the key due to its presence in nearby Costa Rica and Ecuador. The known distribution and habitat preferences of each species are outlined briefly. 相似文献
