The genus Braunsia Kriechbaumer, 1894 from China with description of two new species (Hymenoptera, Braconidae, Agathidinae).

The species of Braunsia Kriechbaumer, 1894 (Hymenoptera, Braconidae, Doryctinae) from China are revised and ten species are recognized. Two new species, B. guangdongensissp. n. and B. shenyangensissp. n., are described and illustrated. B. fumipennis (Cameron, 1899), B. pilosa Belokobylskij, 1986, B. postfurcalis Watanabe, 1937, and B. smithii (Dalla Torre, 1898), are recorded from China for the first time. A key to the Chinese species of the genus Braunsia is provided.

Introduction

Kriechbaumer, 1894, is a medium-sized genus of the subfamily () mostly distributed in the Oriental and Afrotropical regions (Shenefelt 1970; Bhat and Gupta 1977; Yu et al. 2017). Sharkey et al. (2006) treated four nominal genera, Szépligeti, 1902, Cameron, 1911, Watanabe, 1934, and van Achterberg, 1988, as synonyms of s.l. However, (= ) and form a separate group because of the absence of notauli and precoxal sulcus combined with a shallow or nearly flat frons behind the antennal socket. has the pronotum emarginate medio-anteriorly combined with a shallowly impressed frons. Therefore, we provisionally retain as a separate genus because of the apomorphous character states (including the absence of a lateral carina anteriorly on the lateral lobes of the mesoscutum). Hence, we exclude the only species known from China ( Watanabe, 1934, reported from Taiwan and Zhejiang) in this paper (Chen and Yang 2006; Chou and Sharkey 1989). differs also from by the presence of a deep antescutal depression. The remainder of is united by the deeply depressed frons behind the antennal socket. differs by the protuberance on the stemmaticum and a pair of converging grooves medially on the mesoscutum (both are absent in s.s.).

Chou and Sharkey (1989) recorded two species of from Taiwan, viz., Enderlein, 1906, and Bhat & Gupta, 1977. Chen and Yang (2006) proposed a new species ( Chen & Yang, 2006) and reviewed the Chinese species, but they overlooked the two species ( Watanabe, 1937, and Watanabe, 1937) recorded by He et al. (2001) for China. In total, five species of were actually known from China prior to our study.

During our study of Chinese , we discovered ten species of (of which only three were known from China before), , (Cameron, 1899), sp. n., , , , Belokobylskij, 1986, Watanabe, sp. n. and (Dalla Torre, 1898). In this paper both new species are described and illustrated and a key to the Chinese species of is provided. The problematic variation of Enderlein is discussed.

Materials and methods

This study is based on specimens preserved in the Parasitic Hymenoptera Collection of Institute of Insect Sciences, Zhejiang University, Hangzhou, China (), Institute of Zoology, Chinese Academy of Sciences, Beijing, China (), Shanghai Entomological Museum, Chinese Academy of Sciences, Shanghai, China (), the Entomological Museum of the China Agricultural University, Beijing, China () and the Naturalis Biodiversity Center collection, Leiden, The Netherlands ().

The terminology and measurements used follow van Achterberg (1993). All descriptions and measurements were made under a Zeiss Stemi 2000-C microscope; figures were made by a digital camera (Q-Imaging, Micropublisher, 3.3 RTV) attached to a stereomicroscope (Leica MZ APO, Germany) and Auto-Montage Pro version 5.0 software. Type specimens are deposited in the Parasitic Hymenoptera Collection of the Zhejiang University, Hangzhou, China (ZJUH).

Chou and Sharkey (1989) and Chen and Yang (2006) recorded this Indonesian species from Taiwan and Fujian, respectively, but these specimens may be misidentified. According to the description by Chou and Sharkey (1989) and Chen and Yang (2006) their specimens differ from the Indonesian by having a complete and regular basal transverse carina on the propodeum (transverse propodeal carina partly weakly developed and irregular in ) and the large stigmal spot of the fore wing connected to a dark brown band below it (without dark band below stigmal spot in ). Unfortunately, we did not have access to these specimens and their taxonomic position remains uncertain.

This new species is very similar to Watanabe, but differs by having no closed areola on the propodeum; the fore wing with a small isolated stigmal spot; the hind leg black; and vein cu-a of the fore wing almost interstitial.

From “Shenyang”, the type locality of the species.
