Abstract

Background

The records of genus Bubopsis McLachlan, 1898 with species Bubopsis tancrei Weele, 1908 and the genus Nousera Navás, 1923 with species Nousera gibba Navás, 1923 have not been published in China.

New information

The genus Bubopsis McLachlan, 1898 with species Bubopsis tancrei Weele, 1908 and the genus Nousera Navás, 1923 with species Nousera gibba Navás, 1923 are recorded for the first time from China. We provide detailed descriptions and illlustrations of specimens and the collecting information of the specimens are also provided.

Keywords

Bubopsis, Nousera, Ascalaphidae, China

Introduction

Sziráki (1998) proposed the monotypic genus Nousera Navás, 1923 is a junior synonym of Pseudoptynx Van der Weele, 1908. In contrast, Ábrahám and Mészáros (2006) thought that Nousera should be a valid genus name. In the revision on the genus of Nousera, Ábrahám compared the morphological differences between Nousera and Pseudoptynx and described a new species Nousera herczigi from Pakistan. Meanwhile he gave Pseudoptynx a new name Ascapseudoptynx, because Pseudoptynx Van der Weele, 1908 is a junior homonymy of Pseudoptynx Kaup, 1848 in Aves (Oswald and Penny 1991). So the genus Nousera has only two species now, mainly distributed in Laos, Thailand, Pakistan, Malaysia (Ábrahám and Mészáros 2006, Michel 2005). Until now, this genus has not been recorded from China.

The genus Bubopsis McLachlan, 1898 comprises seven species, mainly distributed in Southern Europe, North Africa, Middle East, Southern Arabia Peninsula, Central Asia and India (Alexandrov-Martynov 1926, Aspöck et al. 1980a, Aspöck et al. 1980b, Aspöck et al. 1978, Hölzel 2004, McLachlan 1898, Sziráki 1998, Sziráki 2000, van der Weele 1908). Prior to our study B. tancrei Weele, 1908 was known only from Central Asia (Sziráki 2000).

Materials and methods

Terminology of wing venation follows Wang (2003), while genitalia terminology follows Tjeder (1977).

Photographs of morphological characteristics were taken with a Canon EOS 500D digital camera connected to an Olympus U-CTR30-2 microscope, using UV-C (Application Suite) applied software by United Vision Ltd. Photographs of habitus were taken by a Canon EOS 60D digital camera. All figures were processed in Adobe Photoshop CS5.

All specimens examined are deposited in the Insect Collections of China Agricultural University (ICCAU), Beijing, China.
