The third species of the Neotropical genus Leinendera Carrera, 1945, Leinendera achaeta sp. n., is described from Rio Grande do Sul state, Brazil. The habitus, wing and male terminalia are described and illustrated, and a key to the three Brazilian species is provided.
Asilus group, Neotropical, taxonomy
Asilinae Latreille, 1802 is the most diverse subfamily of Asilidae, including 179 extant genera, and is distributed in all biogeographic regions, except Antarctica (
Currently, the two valid species of Leinendera are restricted to the Neotropical Region (Fig.
In this work, the third species of Leinendera, from Rio Grande do Sul, Brazil, is described and illustrated, and a key to Brazilian species is provided.
This study is based on the examination of specimens housed in the following institutions: CESC–Coleção Entomológica de Santa Cruz do Sul, Santa Cruz do Sul, Brazil and
The wing was detached from the body, placed in xylene for 30 minutes and then mounted in Canada balsam between coverslips. After drying, the cover slips were glued to the edge of a piece of thick paper, which was then pinned with the specimen. The techniques of
The label data are cited in full, with the original spellings, punctuation, and dates. Information presented within square brackets are complementary data not included on the labels. Data from the same specimen, but from different labels, are separated by slashes (/). The map was generated with SimpleMappr.

Length: Body length 11.9 mm; wing length 10.9 mm.
Holotype condition: Right postpedicel and right hind tarsus lost. Detached wing mounted on microslides, terminalia placed in microvial with glycerin, both pinned with the specimen.
Variation (n = 2): Size. Body length 11.5–12.4 mm; wing length 10.1–10.5 mm. Face silvery tomentose; mid femur with 1–3 yellow anterior macrosetae; mid tibiae with 3 yellow long macrosetae anteroventrally.
Female: Unknown.
From the greek achaeta, a = absent and chaeta = bristles, referring to the absence of apical scutellar macrosetae.
All specimens of L. achaeta sp. n. were collected with Malaise traps placed in tobacco, Nicotiana tabacum L., plantations. The vegetation surrounding the tobacco plantations was composed mainly by grasslands and shrubs of small to medium size. No information about the prey is known.
Differs from the other two species of Leinendera by the absence of apical scutellar macrosetae and characters of the terminalia (Figs
