  • four new species and new synonymy in stenocerus schoenherr 1826 coleoptera Anthribidae anthribinae stenocerini
    Zootaxa, 2018
    Co-Authors: Marcela Paes De A M Lopes, Jose Ricardo M Mermudes
    Abstract:

    Three new species from Brazil, Stenocerus christus sp. nov. (Rio de Janeiro, Corcovado), Stenocerus fratris sp. nov. (Espirito Santo, Santa Maria de Jetiba) and Stenocerus mesosternalius sp. nov. (Espirito Santo, Alegre, Fazenda Jerusalem), and a new species from Peru, Stenocerus similis sp. nov. (Mariscau, Juanjui), are described and illustrated. Stenocerus paraguayensis Jordan, 1895 syn. nov. is proposed as a junior synonym of S. fulvitarsis (Germar, 1824). A key to all species of the genus Stenocerus is provided.

  • taxonomy of hylotribus jekel coleoptera Anthribidae anthribinae new synonymies combinations and type designations
    Zootaxa, 2017
    Co-Authors: Fernando Avila Queiroz, Mario Elgueta, Jose Ricardo M Mermudes
    Abstract:

    The type material of six species of Anthribidae from Chile and one from Peru, originally described as Stenocerus Schoenherr and Stenorrhynchus Philippi & Philippi and later transferred to Hylotribus Jekel, was reexamined. These species are Stenocerus asperatus Blanchard, 1851, Stenocerus aspis Erichson, 1847, Stenocerus posticalis Philippi & Philippi, 1864, Stenocerus quadratipennis Germain, 1854, Stenorrhynchus quadrinotatus Philippi & Philippi, 1864, and Stenocerus tuberculosus Blanchard, 1851. Lectotype designations were made for Hylotribus asperatus, Hylotribus quadratipennis , and Hylotribus tuberculosus . New synonyms were established as follows: Hylotribus signatipes (Blanchard, 1851) = H. quadratipennis (Germain, 1854) syn. n., = H. quadrinotatus (Philippi & Philippi, 1864) syn. n., Hylotribus asperatus (Blanchard, 1851) = H. posticalis (Philippi & Philippi, 1864) syn. n.. While, Hylotribus aspis (Erichson, 1847) from Peru was transferred to Piesocorynus Dejean, 1834 and a new combination and synonymy proposed, Piesocorynus aspis (Erichson, 1847) n. comb. = Piesocorynus gracilicornis (Jekel, 1855) syn. n. The genus Hylotribus is defined with five species from Chile and six from Brazil, and the Chilean species are redescribed with illustrations. A new key to all species is included.

  • dimorphism and allometry of systaltocerus platyrhinus and hypselotropis prasinata coleoptera Anthribidae
    Zoologia (Curitiba), 2014
    Co-Authors: Ingrid Mattos, Jose Ricardo M Mermudes, Mauricio Osvaldo Moura
    Abstract:

    Males of sexually dimorphic anthribid species display structural modifications that suggest sexual selection. Polyphenism, which is expressed through morphological and behavioral novelties, is an important component of the evolutionary process of these beetles. In this study, we endeavored to ascertain the presence of variations in selected monomorphic traits, polyphenism in males, and variation in structures associated with sexual dimorphism and allometric patterns in two species: Systaltocerus platyrhynus Labram & Imhoff, 1840 and Hypselotropis prasinata (Fahraeus, 1839). To that end, we used Principal Components Analysis (PCA) and Canonical Variate analysis (CVA) to statistically analyze 26 measurements of 91 specimens. The PCA discriminated three groups (females, major, and minor males) for S. platyrhinus, but only two groups (males and females) for H. prasinata. The same groups discriminated by the PCA for Systaltocerus were confirmed by the CVA analysis, indicating a highly significant variation separating the three groups. We also analyzed positive allometry with respect to prothorax length - independent variable by Reduced Major Axis (RMA). The allometric pattern indicated by most of the linear measurements was strong and corroborates a possible relationship between male polyphenism and the reproductive behavior of major and minor males. We believe that these patterns, in species that show both sexual dimorphism and male polyphenism, are associated with the behavior of defending the female during oviposition, performed by major males.

  • first record of a fungus weevil coleoptera Anthribidae from the upper cretaceous arzamazovskaya formation primorsky krai russian far east
    Cretaceous Research, 2020
    Co-Authors: Andrei A Legalov
    Abstract:

    Abstract A new fungus weevil, Arzamazorhinus neli gen. et sp. nov. belonging to the subfamily Anthribinae is described from Primorsky Krai, Upper Cretaceous, Turonian – Coniacian. The new genus differs from other genera of the tribe Ecelonerini in the ventral antennal scrobes and rather long rostrum. It is distinguished from the genus Cretanthribus Legalov, 2009 (tribe Cretanthribini) fungus weevil described from Cretaceous deposits of Khetana in the Russian Far East, by the pronotum possessing transverse carina, a rather long subparallel rostrum not sagittate at apex, and lacking transverse eyes. This is the first record of Anthribidae from the late Cretaceous and the first coleopteran described from the Arzamazovskaya Formation in the Russian Far East.

  • a new genus of fungus weevils coleoptera Anthribidae in rovno amber
    Fossil Record, 2018
    Co-Authors: Andrei A Legalov, Vitaliy Y Nazarenko, E E Perkovsky
    Abstract:

    Abstract. New fungus weevils, Eduardoxenus unicus (ZooBank registration: urn:lsid:zoobank.org:act:5732 BC85-9148-4FE5-A4F6-46847BA0138D, urn:lsid:zoobank.org: act:4D3B3EA8-AE0E-4E6D-A770-B427AC19ED03) Legalov, Nazarenko et Perkovsky, gen. et sp. nov. (Coleoptera: Anthribidae), are described from late Eocene Rovno amber. The new genus is similar to the genus Cyptoxenus Valentine, 1982, but differs in coarsely faceted eyes, antennomere 2 shorter than antennomere 1 and an almost glabrous body. It differs from the genus Valenfriesia Alonso-Zarazaga et Lyal, 1999 in the coarsely faceted eyes, almost straight transversal carina on the pronotum and distinct elytral humeri, and it differs from the genus Neoxenus Valentine, 1999 in distinct lateral carina on the pronotum, coarsely faceted eyes and almost straight transversal pronotal carina. This fossil fungus weevil is the oldest finding of the tribe Valenfriesiini in fossil state and the first record of the Choraginae from the Eocene amber. The palaeogeographical and palaeoclimatological importance of finding Valenfriesiini in Rovno amber is discussed.

  • micro ct to document the coffee bean weevil araecerus fasciculatus coleoptera Anthribidae inside field collected coffee berries coffea canephora
    Insects, 2018
    Co-Authors: Ignacio Albaalejandre, Javier Albatercedor, Fernando E Vega
    Abstract:

    The coffee bean weevil, Araecerus fasciculatus (De Geer) (Coleoptera: Anthribidae), is a cosmopolitan insect with >100 hosts, and has been reported as a pest of stored coffee. During a study involving the coffee berry borer, we observed coffee bean weevils emerging from field-collected coffee berries and used micro-computerized tomography (micro-CT) scans to observe the insect inside the berry. Two eggs had eclosed inside the berry, resulting in observations of a newly eclosed adult beetle and a 5th instar larva, each feeding on one of the two seeds. This is the first time since 1775, when the insect was first described, that the insect has been observed inside a coffee berry.
