Neolindus brachati sp. n., Neolindus luciamans sp. n.

Zusammenfassung

Zwei Arten der Gattung Neolindus Scheerpeltz, 1933 werden beschrieben, abgebildet und von ähnlichen bzw. geographisch nahen Arten unterschieden: N. luciamans sp. n. ( Peru: Provinz Huanuco) und N. brachati sp. n. ( Venezuela: Provinz Carabobo). Neolindus rudiculus Herman, 1991 wird erstmals seit der Originalbeschreibung nachgewiesen.

Introduction

The subtribe Cylindroxystina is one of the few Neotropical paederine taxa that have been subject to modern revisions. According to Herman (1991), it comprises two genera and 47 species, Cylindroxystus Bierig, 1943 (14 species) and Neolindus Scheerpeltz, 1933 (33 species). Four additional species of Neolindus were described recently by Asenjo (2011) and Irmler (2011).

Both Cylindroxystus and Neolindus have been collected remarkably rarely and in small numbers; numerous species are represented only by single specimens. The revision by Herman (1991) is based on a total of merely 37 ( Cylindroxystus ) and 79 specimens ( Neolindus ), respectively. Most of them were found in leaf litter and at lower elevations, but the reproduction habitat is essentially unknown.

In material of Staphylinidae collected by Volker Brachat (Geretsried) in Venezuela in 2005 and 2007 and by Günter Riedel (München) in Peru in October 2010, five specimens of Neolindus were discovered, a female of unknown identity (probably undescribed), a female of N. rudiculus Herman, 1991 , and three specimens (two males and one female) belonging to two undescribed species from Peru and Venezuela .

Material and methods

The material treated in this study is deposited in the author´s collection.

The morphological studies were conducted using a Stemi SV 11 microscope (Zeiss Germany) and a Jenalab compound microscope (Carl Zeiss Jena). A digital camera (Nikon Coolpix 995) was used for the photographs.

Head length was measured from the anterior margin of the frons to the posterior margin of the head, elytral length at the suture from the apex of the scutellum to the posterior margin of the elytra, total length from the anterior margin of the mandibles to the apex of the abdomen, the length of the forebody from the anterior margin of the mandibles to the posterior margin of the elytra, aedeagal length from the apex of the internal structures or from the apex of the dorsal plate (whichever is the longest) to the base of the capsule. The parameral side of the aedeagus (i.e., the side where the sperm duct enters) is referred to as the ventral, the opposite side as the dorsal aspect.
