New species of Harttia (Loricariidae, Loricariinae) from the Rio Sao Francisco Basin

A new species of the mailed catfish genus Harttia is described from the Sao Francisco River drainage, States of Minas Gerais and Bahia, Brazil. The new species is distinguished from congeners by the combination of an abdominal region covered by small bony plates; plates 3-4 times in eye diameter; interorbital width 3.1-4.0 in head length and greater than eye diameter; body width at anal fin origin 6.3-8.3 in standard length; margins of the head and pectoral fin spine of mature males with elongate and conspicuous odontodes; anal fin of males longer than of females. A key to Harttia species and a comparison with other species are provided.

Description of new cicada species associated with the coffee plant and an identification key for the species of Fidicinoides (Hemiptera: Cicadidae) from Brazil

The genus Fidicinoides Boulard & Martinelli is characterized by its partially exposed timbal, not totally covered by the meta-scutellar plate as occurs in Fidicina Amyot & Serville, and has an extensive geographic distribution in Central and South America. In this work a new species for the genus is described. Fidicinoides sarutaiensis Santos, Martinelli & Maccagnan sp. n. is a medium-sized cicada, with the collected and studied specimens associated with coffee (Coffee arabica L.), in the municipality of Sarutaia, in the southeast region of São Paulo state. The species F. glauca (Goding, 1925) and F. viridifemur (Walker, 1850) are transferred to Dorisiana. An identification key for the Fidicinoides species of Brazil is also proposed.

Trichospilus diatraeae Cherian & Margabandhu, 1942 (Hymenoptera: Eulophidae), a new parasitoidof Melanolophia consimilaria (Lepidoptera: Geometridae)

First report on the parasitoid Trichospilus diatraeae of the genus in Eulophidae found in the field parasitizing pupae of the eucalyptus defoliating looper Melanolophia consimilaria. This opens new perspectives for the use of this parasitoid in biological control programs against caterpillars of forestry importance.

A taxonomic review of Neogriphoneura Malloch, 1924 (Diptera : Lauxaniidae), with description of three new species

The status of the Lauxaniidae genus Rhabdolauxania Hendel, 1925 is reevaluated and is synonymized under Neogriphoneura Malloch, 1924. Three new combinations, N. immaculata (Hendel, 1933), comb. nov., N. laevifrons (Hendel, 1925), comb. nov., and N. schnusei (Hendel, 1925), comb. nov. are proposed. Two lectotypes are designated. Three new species of Neogriphoneura are described: N. bispoi sp. nov., from Santa Catarina, Brazil, N. pacata sp. nov., from La Paz, Bolivia, and N. corrugata sp. nov. from British Virgin Islands. Illustrations of the head, wing, male and female terminalia are provided for the new species. This raises the number of species in the genus from the present five to eleven. A key is provided for the species of the genus.

On certain curves of genus three in characteristic two

We study curves of genus 3 over algebraically closed fields of characteristic 2 with the canonical theta characteristic totally supported in one point. We compute the moduli dimension of such curves and focus on some of them which have two Weierstrass points with Weierstrass directions towards the support of the theta characteristic. We answer questions related to order sequence and Weierstrass weight of Weierstrass points and the existence of other Weierstrass points with similar properties.

Identification of a new repetitive element in the sex chromosomes of Leporinus elongatus (Teleostei : Characiformes : Anostomidae): new insights into the sex chromosomes of Leporinus

Leporinus elongatus represents an interesting model for studies on chromosome evolution since it possesses a conspicuous ZZ/ZW sex chromosome system that has been characterized mainly by basic cytogenetic techniques. In the present study we describe a dispersed repetitive element ( named Le SpeI) related to the sex chromosomes of L. elongatus. Females revealed clusters of Le SpeI on the long arm of the W chromosome and in the acrocentric NOR-bearing chromosome pair. In males, the signal was restricted to the pericentromeric region of the NOR-bearing chromosomes. Considering the results obtained in the present study using FISH, NOR and C-banding, together with findings from previous studies, it can be inferred that the sex chromosome system of L. elongatus is still undergoing an evolutionary process. The data suggest novelties in relation to the sex chromosomes of the genus Leporinus with the description of a multiple sex chromosome system involving the NOR-bearing chromosomes. Therefore, it is hypothesized that the simple ZW chromosome system previously described for L. elongatus rather is a multiple Z(1)Z(1)Z(2)Z(2)/Z(1)W(1)Z(2)W(2) system. Copyright (c) 2007 S.
