Longiconnecta Li & Xing gen. nov.
Type species:NirvanabasimaculataWang & Li,1997
Type species distribution: Guizhou (Xishui).
Description: Apex of head wide-circle produced in dorsal view, length of mid crown almost equal to distance between the eyes, crown border with carina, ocelli located at lateral area of crown near to eyes; frontclypeus slightly rise. Pronotum broader than crown, its middle sometimes with black spot; scutellum triangle, almost as long as pronotum; forewings with four apical cells, appendix narrow.
Pygofer side with ventral process; lateral margin of subgenital plate with long setae; base of aedeagal shaft often with processes; connective Y-shaped, its stem very long; style stick-shaped.
Etymology:Thenameofthenewgenusreferstotheverylongstemofconnective.
Distribution: Oriental Region.
Remarks: This new genus is very similar toNirvanaKirkaldy, but can be distinguished from the later by: 1) crown short; 2) pronotum sometimes with black spot; 3) stem of connective very long.
Longiconneta marginalspota Li & Xing sp. nov. (Fig.1)
Length of body (incl.teg.): ♂, 4.6 mm, ♀5.0 mm.
Holotype: ♂, CHINA: Yunnan, Gaoligongshan; 5 August 2013; coll. Yang Weicheng. Paratype: 1♀, Yunnan, Mengla; 22 July 2013; coll. Liu Yangyang .
Etymology: The species name is derived from the feature of the middle of posterior margin of forewings with a long brown spot.
Remarks:ThisspeciesissimilartoLongiconnectabasimaculata(Wang & Li), but can be distinguished from the later by: 1) pronotum without black spot; 2) middle of the posterior margin of forewings with a black spot; 3) aedeagal shaft with a fork-shaped long process at the dorsal margin.

Abstract:This paper describes a new genus, Longiconnecta gen. nov. (type species: Nirvana basimaculata Wang & Li, 1997) and a new species, L. marginalspota sp. nov., in the tribe Nirvanini, from China. Three new combinations: L. basimaculata (Wang & Li) comb. nov., L. albula (Cai & Shen) comb. nov., and L. flava (Cai & He) comb. nov. are also proposed. The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).
