Bayadera hatvan Hämäläinen & Kompier, 2015

( Fig. 6a–e View FIGURE 6 )

Bayadera hatvan: Hämäläinen & Kompier (2015) , pp. 15–19, Figs 1 View FIGURE1 , 3–5 View FIGURE3 View FIGURE 4 View FIGURE 5 [Holotype from Yen Bai Prov., paratypes from Yen Bai, Ha Giang and Cao Bang Provinces].

Materials examined. [ Vietnam] 2♂, Ha Giang Prov., 1.VII.2014, T. Kompier (TKC) ; 1♂ 1♀, Thanh Cong, Nguyen Binh , Cao Bang Prov., 17.V.2015, Q.T. Phan and F. Hayashi leg. ( PQTC) ; 1♂, Tu Le, Mu Cang Chai , Yen Bai Prov., 19.V.2014, Q.T. Phan leg. ( PQTC) ; 1♂, Nam Bung , Yen Bai Prov., 11.V.2014, T. Kompier leg. (TKC).

Other materials confirmed by field observations. [ Vietnam] 15 exs, Cao Bang Prov., 18.VI.2015, T. Kompier ; 1♂, Cao Bang Prov., 27.VI.2015, T. Kompier; Some individuals, Yen Bai Prov. , V, VI, VII.2014, VI, VII.2015, VII.2016, VII.2017, T. Kompier.

Notes. Bayadera hatvan resembles B. indica ( Selys, 1853) . In both species the tip of cerci is dilated in the form of a triangle, the inner sides have a robust spine near the base and two tubercles besides the robust spines ( Fig. 6b– c View FIGURE 6 ). Wings ( Fig. 6d View FIGURE 6 ) are hyaline, but darkened at the tip. Female resembles the male in thoracic marking; posterior lobe of prothorax has two short processes ( Fig. 6e View FIGURE 6 ). Hämäläinen & Kompier (2015) presumed that specimens from Yunnan, southern China, identified by Davies & Yang (1996: p. 152, Figs 26–28) as Bayadera indica are likely to be B. hatvan rather than B. indica . A re-evaluation of Chinese specimens should resolve this matter.

Distribution. Vietnam (Ha Giang, Cao Bang and Yen Bai Provinces).
