A remarkable new Veturius (Veturius) of the Brazilian Central Amazonas,with an inventory of the genus in Brazil (Coleoptera: Passalidae)

A new species of Veturius (Veturius) Kaup, of Brazil, Central Amazonas, lower basin of Urucu, Tefé and Coari, is described and illustrated. V. urucuensis n. sp. belongs to the “cephalotes” species group, and has an external autapomorphy for the family Passalidae: a large tuft of setae on the medioposterior area of the metasternum. The species is closely allied to V. jolyi Boucher, 2006, from the Brazil-Venezuela-Guyana border. The peculiar endemism of the new species suggests an intra-continental island vicariance into the Amazon Basin. No similar process was known in the large genus Veturius. A complete inventory of the 22 Veturius species in Brazil is given, with their distribution, and following the previously established monophyletic species groups. From Brazil, two species are newly reported, V. (Ouayana) guyanensis Boucher, 2006 (Pará) and V. (O.) dominicae Boucher, 2006 (Roraima), and one species is confirmed, V. (O.) unicornis Gravely, 1918 (Amazonas). New details are given on some other Brazilian Veturius.     

A new blue-grey Veturius (Publius) Kaup of the northwestern Sierra de Talamanca,Costa Rica (Coleoptera: Passalidae)

A new species of Veturius (Publius) Kaup, V. unanus n. sp., from a mountain cloud forest of Costa Rica, northwestern Sierra de Talamanca, Tapantí-Río Macho Massif, Province of Cartago, is described and illustrated. It is the first known Publius species with a blue-grey body color, matt elytra and shining or satiny elsewhere. The species is interpreted as sister species of V. (Publius) talamacaensis Boucher, 2006, from which it differs by a few characters. Both species are sympatric. V. unanus n. sp. is the northernmost endemic in the subgenus Publius.     

A new Veturius (Veturius) of the “cephalotes” group from southern Colombia,Putumayo (Coleoptera: Passalidae)

A new species of Veturius (Veturius) Kaup from southern Colombia, Putumayo, lowland forests, is described and illustrated. V. paya n. sp. belongs to the South American “cephalotes” species group and is sister species of V. cephalotes (Le Peletier & Serville, 1825). Both species are distinguished by few characters of the head and thorax. They seem to be allopatric close to the western distributional limits of V. cephalotes. The endemism of V. paya n. sp. corresponds to a geographic vicariance in the axis of the Amazon Basin. An overview is given on the phylogeny and the chorology of the completed “cephalotes” species group.     

Do species of Neacratus with anchor-shaped sclerite of endophallus really belong to Neacratus (Coleoptera: Brentidae: Acratini)?

A small group of nine nominal species belonging to the genus Neacratus Alonso-Zarazaga, Lyal, Sforzi & Bartolozzi, 1999 is studied in detail from a morphological point of view. Lectotypes are designated for Brentus obtusus Lund, 1800 and Nemocephalus fulgidus Kleine, 1928. Three new synonymies are proposed: Nemocephalus brevicostatus Kleine, 1922 n. syn. for Brenthus obtusus Lund, 1800, Nemocephalus longiceps Perroud, 1853 n. syn. for Brenthus famulus Boheman, 1840, and Nemocephalus fulgidus Kleine, 1928 n. syn. for B. famulus Boheman, 1840. A new species, Neacratus pascali n. sp., is described from French Guiana. New country records are provided for Neacratus obtusus (Bolivia, Ecuador, French Guiana, Grenada, Peru, Trinidad and Tobago, Venezuela), N. puncticeps (Sharp, 1895) (Colombia, Ecuador, Venezuela), N. guatemalensis (Senna, 1893) (Belize, Colombia, El Salvador), N. deplanatus (Sharp, 1895) (Colombia, Costa Rica, French Guiana, Mexico, Panama, Venezuela) and N. famulus (Paraguay). A phylogenetic analysis carried out on this group shows it forms a monophyletic lineage included in a clade containing most of other species of Neacratus, of which it is the type species; it is therefore not justified to create a new generic name. The possible polyphyletism of the genus Neacratus as a whole and the development of an excessively long rostrum in some male Acratini are discussed.     

Description and phylogeny of a new Neotropical genus of Acalyptini (Coleoptera: Curculionidae: Curculioninae) associated with the staminodes of Cyclanthaceae

The weevil genus Azotoctla gen. nov. (Coleoptera: Curculionidae: Curculioninae: Acalyptini Thomson), is described to accommodate the following 15 new Neotropical species: Azotoctla aecuatorialis sp. nov. (Ecuador), Azotoctla anerunca sp. nov. (Ecuador), Azotoctla angustacra sp. nov. (Ecuador), Azotoctla curvirostra sp. nov. (Peru), Azotoctla dasygastra sp. nov. (Costa Rica and Honduras), Azotoctla femorata sp. nov. (Colombia, Costa Rica, Ecuador and Panama), Azotoctla gomezi sp. nov. (Colombia, Costa Rica and Panama), Azotoctla gottsbergeri sp. nov. (Brazil), Azotoctla clemmyssa sp. nov. (Colombia), Azotoctla melolauta sp. nov. (Colombia), Azotoctla migueli sp. nov. (Colombia), Azotoctla nana sp. nov. (Panama), Azotoctla punctata sp. nov. (Costa Rica), Azotoctla tibiatra sp. nov. (Belize), and Azotoctla tuberquiai sp. nov. (Colombia). Azotoctla is placed in the tribe Acalyptini, subtribe Staminodeina Franz, thus representing the sister taxon of Staminodeus Franz. The monophyly of Azotoctla is supported by the following inferred traits: a noncarinate rostrum that is tumescent above the antennal insertion in males; equilaterally subtriangular hemisternites of the male sternum 8; paired, longitudinal, laterally positioned sclerites of the aedeagus; and a bifurcate lamina of the female sternum 8, which bears explanate, diverging furcal arms. A key to the species of Azotoctla is provided; and the salient features of each species are illustrated and presented along with distributional and natural history data. A morphological cladistic analysis of 23 terminal species (eight outgroup, 15 ingroup) and 33 characters yielded a single most parsimonious cladogram (length = 75 steps, consistency index = 52, retention index = 77), with the ingroup topology ((A. aecuatorialis, (A. anerunca, A. gottsbergeri)), (A. punctata, ((A. angustacra, A. nana), (A. tibiatra, (A. clemmyssa, (A. curvirostra, A. femorata)), (A. melolauta, ((A. gomezi, A. migueli), (A. dasygastra, A. tuberquiai))))))). Species of Azotoctla are reproductively associated with the ephemeral staminodes of different members of the Neotropical monocot family Cyclanthaceae; most commonly with the widespread genus Carludovica Ruiz & Pavón. The interspecific homogeneity in external morphology, coupled with marked differences in genital traits and an apparent absence of narrow geographical ranges mediated by either host plants and/or biogeographical factors, jointly suggest that the diversification of Azotoctla is a relatively recent phenomenon and driven strongly by sexual selection. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 166 , 559–623.     

Two new species of the Empis (Leptempis) rustica group of the Mediterranean basin (Diptera: Empididae: Empidinae)

Two new species of the Empis (Leptempis) rustica group are described: E. (L.) tenuis n. sp. and E. (L.) lauriauti n. sp. Both were mainly collected in mountainous areas of the Mediterranean basin; the first species was collected in Morocco and Southern Spain; the latter was found in late summer in the Southern Alps in France. The key to species of the Empis (L.) rustica group is updated to include these two new species as well as a recently described Caucasian species.     

Three new species in the neotropical genus <Emphasis Type="Italic">Clidemia</Emphasis> (Melastomataceae: Miconieae)

We here propose and describe three new species of Clidemia: C. aguilarii from Costa Rica and Panama; C. aurantiaca from Costa Rica, Panama, and Ecuador; and C. subpeltata, a Costa Rican endemic. Phenological notes, distribution maps, line drawings, color images of the live plants in the wild, and discussions comparing the new species to their presumed closest relatives are provided.     

Two new species of Larinus Dejean from North Africa (Coleoptera: Curculionidae), with a key to the striped Larinus (s.str.)

Two new sibling species, Larinus synthesys n. sp. from Algeria, and Larinus boroveci n. sp. from Algeria and Morocco, are described. Both species are tentatively assigned to the subgenus Larinus based on resemblance to species having longitudinal stripes on the elytra and rostrum. L. synthesys n. sp. is the smallest species in Larinus (s. str.) and is closely related to L. boroveci n. sp. The lectotype of Larinus cardopatii Lucas, 1847 is designated and redescribed. An illustrated key to the striped Larinus (s. str.) is given.     

Revision of the species of the Tychus rufus group (Coleoptera: Staphylinidae: Pselaphinae)

The species belonging to Tychus rufus group are revised. Eleven species are recognized, described and illustrated and a key to their identification is provided. Nine taxa are new to science: Tychus carpathius n. sp. from Karpathos island (Greece); T. torticornis n. sp. from Lesbos Island (Greece); T. pisidicus n. sp. and T. inermis n. sp. from southwestern Turkey; T. antiocheus n. sp. and T. effeminatus n. sp. from southeastern Turkey; T. artvinensis n. sp. from northeastern Turkey, and T. sidonicus n. sp. and T. libanus n. sp. from Lebanon.     

Descriptions of new Neotropical Lycoperdininae (Coleoptera: Endomychidae) and their phylogenetic placement

Two new genera and three new species of Lycoperdininae (Coleoptera: Endomychidae) from South America, are described and illustrated based on adults: Hylaperdina n. g., along with H. brevicornis n. sp. from Ecuador and H. costariciensis n. sp. from Costa Rica, and Chileanus n. g., along with C. talca n. sp. from Chile. Their most likely placement within the Lycoperdininae is discussed. A key to genera of the neotropical Lycoperdininae is provided.     

The oldest occurrence of immature Diptera (Insecta), Middle Triassic,France

The oldest fossil Diptera are known from the Grès à Voltzia Formation (Upper Buntsandstein) of the northern Vosges Mountains (northeastern France), the age of which is early Anisian (early Middle Triassic). Six monotypic genera assigned to all the major lineages of Diptera (except for the Culicomorpha) were described from these beds based on adults (Krzeminski et al. 1994; Krzeminski & Krzeminska 2003). Immature Diptera also occur in the Grès à Voltzia (ca 30 specimens). Pupae are abundant whereas the larvae are extremely rare. The most numerous and well-preserved pupal type has been assigned to Voltziapupa n. gen. (V. tentata n. sp. and V. cornuta n. sp.). These pupae display plesiomorphic characters combined with possibly derived ones. Among the larvae, Anisinodus crinitus n. gen., n. sp. shows culicomorph features. It represents the earliest Culicomorpha (Chironomoidea inc. fam.) known up to date. The other types of dipteran immatures (six pupal and two larval ones) occurring in the Grès à Voltzia are less well preserved, so that their systematic position is difficult to determine and they have been assigned to the Nematocera incertae sedis. These immature Diptera are the first ones recorded from the Triassic.     

New species,new geographical records of Neoibidionini and description of the females of Compsibidion paradoxum Martins, 1971 and Glomibidion trinidadense (Gilmour, 1963) (Coleoptera: Cerambycidae)

Two new species of Neoibidionini from Colombia are described: Psiloibidion boteroi n. sp. and Tropidion neisi n. sp. The previous key to species of Tropidion is modified to include the new species. The females of Compsibidion paradoxum Martins, 1971 and Glomibidion trinidadense (Gilmour, 1963) are described and illustrated for the first time. Moreover, the geographical distribution is expanded for nine species of Neoibidionini.     

Species level taxonomy of the Neotropical hairstreak genus Porthecla (Lepidoptera: Lycaenidae: Theclinae: Eumaeini)

The species level taxonomy of Porthecla is revised. Six previously described species are recognized: P. ravus (Druce 1907); P. barba (Druce 1907); P. dinus (Hewitson 1867); P. porthura (Druce 1907); P. minyia (Hewitson 1867); P. gemma (Druce 1907), and another six new species are proposed: P. forasteira Faynel & Moser n. sp.; P. annette Faynel & Robbins n. sp.; P. johanna Faynel & Robbins n. sp.; P. peruensis Faynel & Moser n. sp.; P. prietoi Faynel & Busby n. sp. and P. willmotti Busby, Faynel & Moser n. sp. For each Porthecla species we present diagnostic characters, images of male and female adults, drawings of male and female genitalia, distribution maps, and notes on habitat and other biological traits. An identification key for males is provided. To stabilize names; lectotypes are designated for Thecla minyia Hewitson 1867, and Thecla gemma Druce 1907. Wing pattern resemblances between Porthecla and other genera are discussed.

Three new species of Philocorydoras Suriano, 1986 (Monogenoidea: Dactylogyridae) infecting the gills of callichthyids (Actinopterygii: Callichthyidae) from the Peruvian Amazonia

During a research on gill ectoparasites of callichthyids fishes from the Peruvian Amazonia, the following monogenoideans were found: Philocorydoras peruensis n. sp. from Corydoras splendens (Castelnau); Philocorydoras multiradiatus n. sp. and Philocorydoras jumboi n. sp. from Brochis multiradiatus (Orcés, V.). All new species described herein are mainly differentiated from their congeners based on the morphology of the copulatory complex. In P. peruensis n. sp. the cirrus is “J”-like shaped tube slightly tilted to one side, while in P. jumboi n. sp. is “J”-like shaped tube in a straight position and in P. multiradiatus n. sp. the cirrus is an arced tube with inflated base and distally narrow. Brochis (Orcés, V.) represents a new genus hosting species of Philocorydoras. All new species presented in this work represent the first species of Philocorydoras reported for Peru.
