Introduction

Leinendera Carrera, 1945 is characterized by thepresence of apical scutellar setae; wing with spot (dense microtriquia) on third apical; tergites with lateral marginal macrosetae; epandrium more or less conical, with dense setae and ovipositor short, more or less conical, without spines (Carrera 1945).

Leinendera is a monotypic genus and Carrera (1945) described the type-species, Leinendera rubra based on holotype (Rio de Janeiro city, Brazil) and 3 paratypes, 1 male and 2 females (Rio de Janeiro city and São Paulo (Juquiá, Santo André (Paranapiacaba), Brazil).

Carrera (1945) also remarked on the similarity between Leinendera and Glaphyropyga Schiner (Schiner 1866), and provided illustrations of postpedicel, thorax in dorsal view, wing, mid right leg, male terminalia in ventral view and lateral view, and ovipositor in lateral view of Leinendera rubra. Posteriorly, Artigas & Carrera-Suárez (2011) described and illustrated the female terminalia of L. rubra.

In this work it is described and illustrated a new species for Leinendera from Rio de Janeiro state, Brazil and it is provided illustrations and diagnosis of L. rubra.

 

Materials and Methods

The present study examined specimens housed in Instituto Oswaldo Cruz (IOC), Rio de Janeiro, Rio de Janeiro, Brazil.

Morphological terminology follows Cumming and Wood (2009). Detached wings were mounted on microslides in Canada balsam. After gluing a microslide to the edge of a piece of thick paper, the specimen was pinned to the paper so that the slide was directly next to the specimen pin. Dissected terminalia were placed in a 10% KOH solution at 40 ºC for 8 hours, washed in water, treated with 10% acetic acid, and subsequently examined in concavity slides in glycerin. After examination and illustration, the detached parts were placed in microvials with glycerin and pinned with their respective specimens.

The label data is cited in full, with the original spellings, punctuations, and dates. Information presented within square brackets is complementary data not included on the labels. For corrections of localities are used parentheses. Data for the same specimen but from different labels are separated by slashes (/).

Discussion

L. nigra sp. n. is externally similar to L. rubra.Both species possess stripes on pleuron (Figures 1a, 3a, b) and 1/3 apical of wing with dense microtrichia (Figures 1d, 3f). However, L. nigra sp. n. can be separated from L. rubra by characters presented in the diagnoses of both species and terminalia.
