A new species of Ampulicomorpha (Hymenoptera: Embolemidae) from China.

Embolemidae (Hymenoptera: Chrysidoidea) are parasitoids of Hemiptera Auchenorrhyncha (Olmi 199fi, 1999). Ampulicomorpha Ashmead, 1893, is found in all zoogeographical regions. Twenty species have been described lOlmi 1996, 1997, 1998, 1999, 2004a, 2004b, 2006, 2010; van Achterberg & van Kats 2000; Azevedo & Amarante 2005; Ortega-Bianco et al. 2011) and the genus was revised by Olmi (1996, 1997) and van Achterberg & van Kats (2000).

The species of Ampulicomorpha from China has been studied mainly by Xu et al. (2001). In 2012 the authors examined additional specimens of Ampulicomorpha from China, and have found one new species, which is described herein.

MATERIALS AND METHODS

The descriptions follow the terminology used by Olmi (1994, 1996, 1999) and Xu et al. (2012). The measurements reported are relative, except for the total length (head to abdominal tip, without the antennae). In the descriptions, POL is the distance between the inner edges of the 2 lateral ocelli; OL is the distance between the inner edges of a lateral ocellus and the median ocellus; OOL is the distance from the outer edge of a lateral ocellus to the compound eye; OPL is the distance from the posterior edge of a lateral ocellus to the occipital carina; TL is the distance from the posterior edge of an eye to the occipital carina.

The types of all species of Ampulicomorpha have been examined.

The opposite sexes of Ampulicomorpha species are very different, so that the association is difficult. Waiting for the correct attribution to the females of the above males (maybe by DNA analysis), the following keys to the females and males of the Oriental species of Ampulicomorpha can be presented:
