Two new species of Corimbion Martins, 1970 are described from Bolivia: Corimbion kuckartzi and Corimbion ledezmae. A previous key to the South American species of Corimbion (Martins 2009) is herein modified to include the new species. Dorsal, ventral and lateral habitus illustrations, as well as variation in color and dorsal pattern for C. kuckartzi, are also presented.
Two new species of Eburiini (Coleoptera, Cerambycidae, Cerambycinae) are described from Mexico (Guerrero): Susuacanga boteroi; and Eburia (Eburia) girouxae. Both are included in previous keys.
In this paper the primary types of Centris bees described by the British entomologist Theodore Dru Alison Cockerell deposited in the Natural History Museum (London) and the Oxford University Museum of Natural History (Oxford) in the United Kingdom, as well as in the United States National Museum (Washington), American Museum of Natural History (New York), the Academy of Natural Sciences of Drexel University (Philadelphia), and in the California Academy of Sciences (San Francisco) in the United States were studied. To stabilize the application of the name C. lepeletieri (= C. haemorrhoidalis (Fabricius)), a lectotype is designated. The study of the primary types allow proposing the revalidation of C. cisnerosi nom. rev. from the synonymy of C. agilis Smith, C. nitida geminata nom. rev. from C. facialis Mocsáry, C. rufulina nom. rev. from C. varia (Erichson), C. semilabrosa nom. rev. from C. terminata Smith and C. triangulifera nom. rev. from C. labrosa Friese. Centris bakeri syn. nov., C. bimaculata carrikeri syn. nov., C. fusciventris matoensis syn. nov., C. heterodonta syn. nov. and C. elegans grenadensis syn. nov. are proposed as a new junior synonyms of C. varia, C. claripennis Friese nom. rev., C. caurensis, C. dentata Smith and C. elegans Smith, respectively. Centris ruae is withdrawn from the synonymy of C. transversa Pérez and proposed as a new junior synonym of C. nitida Smith. In addition, a lectotype for C. buchholzi Herbst (= C. wilmattae) is designated. Information on the repository of the lectotype of C. lepeletieri and images of most primary types studied here are also provided.
The gigas species group of the subgenus Canthidium (Neocanthidium) is defi ned and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identifi cation key and comments on the distributions of the species of the gigas group.
Abstract. Six new species of Coleoxestia Aurivillius, 1912 (Cerambycidae, Cerambycinae, Cerambycini) are described: C. clarkei from Bolivia; C. chemsaki and C. eyai from Peru; C. fragosoi and C. rafaeli from Brazil; and C. hovorei from Ecuador. Coleoxestia rachelae Eya and Chemsak is also newly recorded from Peru (new country record). Dorsal, ventral and lateral illustrations along with illustrations of various other structures are provided for each of the new species. In some cases, existing key couplets by Eya and Chemsak (2005) or Martins and Monné (2005) are modifi ed to help separate a new species from similar existing species. A reproduction of the general descriptive terminology for the head, prothorax and antennomeres of Coleoxestia, from Fragoso (1993), is also included in the illustrations.
We provide the first comprehensive taxonomic revision of the poorly known South American butterfly genus Zischkaia Forster, 1964, hitherto regarded as including three described species. A phylogenetic analysis based on DNA sequence data shows that Zischkaia is monophyletic and consists of two morphologically diagnosable clades. Morphological characters and DNA 'barcodes' support the recognition of twelve species in the genus, a significant increase even for the relatively poorly studied subtribe Euptychiina. Consequently, nine new species are described and named herein, including Z. arctoa Nakahara, sp. nov., Z. chullachaki Nakahara & Zacca, sp. nov., Z. baku Zacca, Dolibaina & Dias, sp. nov., Z. arenisca Nakahara, Willmott & Hall, sp. nov., Z. argyrosflecha Nakahara, L. Miller & Huertas, sp. nov., Z. abanico Nakahara & Petit, sp. nov., Z. josti Nakahara & Kleckner, sp. nov., Z. mielkeorum Dolibaina, Dias & Zacca, sp. nov. and Z. warreni Dias, Zacca & Dolibaina, sp. nov. In addition, a neotype is designated for Satyrus pacarus Godart, [1824], and lectotypes are designated for Euptychia amalda Weymer, 1911, Euptychia fumata Butler, 1867 and Euptychia saundersii Butler, 1867.
Kempfidris : a new genus of myrmicine ants from the Neotropical region (Hymenoptera: Formicidae)
(2014)
The new genus Kempfidris gen. nov. is described based on the workers of a single species, K. inusualis comb. nov., from Brazil, Ecuador, and Venezuela. Kempfidris inusualis comb. nov. was originally described by Fernández (2007) and provisionally placed in Monomorium awaiting a better understanding of the internal relationships in Myrmicinae. Kempfidris gen. nov. has a series of distinctive morphological characters including the mandibular configuration, vestibulate propodeal spiracle, propodeal carinae, and cylindrical micro-pegs on the posteromedian portion of abdominal tergum VI and anteromedian portion of abdominal tergum VII. This last trait appears to be autapomorphic for the genus.
A new monotypic genus of Iassinae Walker, 1870 tribe Hyalojassini Evans, 1972 is proposed based on Guaricicana borgesi gen. et sp. nov. from the states of Paraná and Rio de Janeiro, southern and southeastern Brazil, respectively. Detailed descriptions and illustrations of males and females are provided, as well as comparisons with the presumably more closely related genus, Daveyoungana Blocker & Webb, 1992.
The present work provides the first record of the genus Dinotrema Foerster, 1862 in the Neotropical region. Four new Neotropical species are described and illustrated: D. multiareolatum Peris-Felipo sp. nov., D. plaumanni Peris-Felipo sp. nov., D. subbidentatum Peris-Felipo sp. nov., and D. teutoniaense Peris-Felipo sp. nov. The following new combinations are suggested for Nearctic species: Dinotrema angusticornis (Fischer, 1969) comb. nov., D. armillariae (Fischer, 1969) comb. nov., D. bucculatricis (Fischer, 1969) comb. nov., D. caudatulum (Fischer, 1969) comb. nov., D. clayensis (Fischer, 1969) comb. nov., D. communis (Fischer, 1969) comb. nov., D. disstriae (Fischer,1969) comb. nov., D. pauperum (Fischer, 1969) comb. nov., D. saileri (Fischer, 1969) comb. nov., D. shannoni (Fischer, 1969) comb. nov. and D. sylvaticae (Fischer, 1969) comb. nov. An identifi cation key of the all New World Dinotrema species is provided.
