A new species and synonymy in Atrypanius Bates (Coleoptera, Cerambycidae, Lamiinae) from the Brazilian Amazon forest

Abstract

Atrypanius jauffretisp. nov. is described from Brazil (Pará). Nyssodrys grisellaBates, 1864 (currently, Atrypanius grisellus) is synonymized with Lepturges lineatocollisBates, 1863 (currently, Atrypanius lineatocollis), and the species is recorded for the Brazilian states of Rondônia and Mato Grosso.

INTRODUCTION

The specimens of the new species were collected by the French biologist Pierre Edward Jauffret, who defended the preservation of the Amazon and was murdered in 2009 in Santo Antônio do Tauá (Brazil, Pará). He bought land in Santo Antônio do Tauá, where for more than 40 years kept the entire area conserved for research, often facing conflicts alone against the clearing of the forest and the invasion of one of the few conserved areas in the northeast Pará. Unfortunately, the Brazilian state of Pará is one of the dangerous places in the country for those who defend the preservation. This can be confirmed with a simple search in newspapers and with information provided by the Comissão Pastoral da Terra (Pastoral Land Commission), an organ of the National Conference of Bishops of Brazil (Brazilian Roman Catholic Church). Most striking is the fact that the vast majority of cases of violence and murder remain only as statistics, with no punishment for those found guilty.

AtrypaniusBates, 1864 is exclusively American, occurring from eastern United States of America to southern South America, with 27 known species. Of these, 19 are recorded from Brazil, and 14 in the Brazilian Amazon. With the description of a new species and the synonymy of another, both from the Amazon rainforest, these numbers remain unchanged.

MATERIAL AND METHODS

Photographs were taken in the MZSP with a Canon EOS Rebel T3i DSLR camera, Canon MP-E 65 mm f/2.8 1-5X macro lens, controlled by Zerene Stacker AutoMontage software. Measurements were taken in “mm” using measuring ocular Hensoldt/Wetzlar - Mess 10 in the Leica MZ6 stereomicroscope, also used in the study of the specimens.

Type material: Holotype male from BRAZIL, Pará: Ulianópolis, Fazenda São Lucas, 01.I.2002, Jauffret leg. (MZSP). Paratypes - 1 ♂, same data as holotype except for 31.XII.2001, ex larva from Ficus sp. (MZSP); 1 ♂, same data as holotype except for 06.I.2002 (MZSP); 1 ♂, same data as holotype except for 08.I.2002, ex larva from Ficus sp. (MZSP).

Etymology: The new species is named in honor of the late Pierre Edward Jauffret.

Remarks:Atrypanius jauffretisp. nov. is similar to A. irrorellusBates, 1885, but differs especially by the elytral pubescent pattern formed by two areas with dense pubescence, and with distinct white central pubescent macula (with irregular small pubescent spots and without white pubescent macula in A. irrorellus). The other species of the genus cannot be confused with the new species, either by the pattern of pubescence distribution and/or general body shape.

Bates (1863) described the pronotum of Lepturges lineatocollis (Fig. 1E) as “grey, with five black vittae, the middle one much the broadest.” Later, Bates (1864) described the pronotum of Nyssodrys grisella (Fig. 1F) as having the “surface tawny grey; disk with three dark brown vittae.” Apparently, when describing N. grisella,Bates (1864) disregarded the two outermost bands of the pronotum, which were considered in the description of L. lineatocollis. Examination of photographs of the holotype of both species shows that the number and position of the dark bands of the pronotum are identical in both species. Furthermore, the elytral pubescence is nearly identical on basal half, being slightly different only on posterior half. This difference appears to be only intraspecific variation. As there is no other differences (e.g., body shape, prothoracic shape, elytral sculpturing, elytral shape, etc.), Nyssodrys grisella is synonymized with Lepturges lineatocollis.
