Abstract
ABSTRACT Embolemidae (Hymenoptera: Chrysidoidea) are parasitoids of Hemiptera Auchenorrhyncha. The genus Embolemus Westwood, 1833 is present in all zoogeographical regions and 32 species have been described. Embolemus sensitivus sp. nov. is described from the following localities of China: Naban River National Nature Reserve (Yunnan), Mt. Lushan (Taiwan), Mt. Wuyishan (Fujian), Mt. Qinliangfeng and Mt. Wuyanling (Zhejiang).

Embolemidae (Hymenoptera: Chrysidoidea) are parasitoids of Hemiptera Auchenorrhyncha (Olmi 1996 (Olmi , 1999 . Embolemus Westwood 1833, is found in all zoogeographical regions. About 32 species have been described (Olmi 1996 (Olmi , 1998 (Olmi , 1999 (Olmi , 2004a (Olmi , 2004b (Olmi , 2004c (Olmi , 2006 (Olmi , 2010 Amarante et al. 1999; van Achterberg & van Kats 2000; Olmi & Portuondo Ferrer (2003) , Azevedo & Amarante 2005; Ortega-Blanco et al. 2011 ) and the genus was revised by Olmi (1996 and van Achterberg & van Kats (2000) .

The species of Embolemus from China have been studied mainly by . In 2012 the authors examined additional specimens of Embolemus from China, and have found one new species described herein.
MATERIALS AND METHODS
The descriptions follow the terminology used by Olmi (1994 Olmi ( , 1996 Olmi ( , 1999 . 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 two 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.
MATERIALS AND METHODS
The types of all species of Embolemus have been examined.
MATERIALS AND METHODS
The material studied in this paper is deposited in the following collections: tinct; POL = 2; OL = 2; OOL = 6; OPL = 5; TL = 6; face without median furrow; eye small, approximately 0.5 as long as head (11:23); region of head from clypeus to antennal toruli with two longitudinal and median sutures very convergent. Palpal formula 6/3. Pronotum very short, with median longitudinal furrow. Scutum shiny, unsculptured. Notauli incomplete, reaching approximately 0,25 length of scutum. Scutellum shiny, unsculptured. Metanotum shiny, short, transverse, unsculptured. Propodeum dull, reticulate rugose; dorsal surface without median longitudinal keels from anterior margin to posterior surface. Mesopleuron and metapleuron shiny, smooth, unsculptured. Meso-metapleural suture distinct and complete. Forewing hyaline, completely slightly darkened; 1 SDC cell open. Hindwing hyaline, completely slightly darkened. Proximal membranous process of paramere with many sensorial filaments located on distal and subdistal region, without papillae (Fig. 1C) . Tibial spurs 1, 2, 2.
Hosts
Unknown.
Etymology
This specific name means that the proximal membranous process of the paramere has many sensorial filaments.
Remarks
The Oriental species of Embolemus are the following:
Remarks
Embolemus walkeri Richards 1951. The holotype is a female specimen deposited in BMNH and collected in China (Zhejiang Province, near Ning-Po, Da-Laen-Saen, 500-2500 ft., 5-16.XI.1893, with ants, J.J. Walker leg.); a female paratype in ELKU has been collected in Japan (Honshu, Fukushima Prefecture, Akai, Minato-Muna, 29.IV.1950, in nest of Myrmica sp. (Formicidae), Y. Kurosawa leg.). Olmi (1996) considered erroneously this species a junior synonym of Embolemus ruddii Westwood 1833 . However, van Achterberg & van Kats (2000 considered it a good species separated from E. ruddii, though the differences are inconspicuous, as in all females of Embolemus. We believe that the opinion of van Achterberg & van Kats is correct. E. walkeri is a good Oriental species, though present also in the central part of Japan (as it happens in many Oriental species of Dryinidae spreading to the central regions of Japan from the Ryukyu Islands). The above two females are the only known specimens of E. walkeri. The male is unknown.
Remarks
Embolemus krombeini Olmi 1996. The holotype is a female specimen deposited in CAS and collected in India (Maharashtra, Poona, 16.I.1962, E.S. Ross & D. Cavagnaro leg.). The above is the only known female specimen. On the contrary many males are known, usually collected by Malaise traps or yellow pan traps. However, as the opposite sexes of the Embolemus species are very different, the attribution of the above males to E. krombeini is only tentative. Males of this species are known from many Oriental countries: Brunei, China, Indonesia, Laos, Malaysia, Philippines, Sri Lanka, Thailand, Viet Nam. In China the following localities are known:
