Thabena litaoensis Yang, 1994 View in CoL

Gelastyrella litaoensis Yang, 1994: 90 View in CoL (in Chan & Yang, 1994). Gelastyrella hainanensis Ran et Liang, 2006: 65 , figs 1–8, syn. n. Thabena litaoensis Gnezdilov, 2009: 80 View in CoL . Thabena hainanensis Gnezdilov, 2009: 80 View in CoL .

Material examined ( MNHN). Vietnam: 1♂ 1♀, “Museum Paris, Tonkin, Hoa Binh, J. de Cooman, R. Oberthur 1919”; 2♂ 2♀, “Museum Paris, Tonkin, rég. de Hoa Binh, A. de Cooman 1926”; 2♀, “Museum Paris, Tonkin, rég. de Hoa Binh, A. de Cooman 1928”; 1♀, “Museum Paris, Tonkin, rég. de Hoa Binh, A. de Cooman 1929”.

Distribution. China (Hainan) ( Ran & Liang, 2006a; Zhang & Chen 2012), Taiwan ( Chan & Yang, 1994), Vietnam (new record).

Note. The drawings of male genitalia of T. litaoensis and T. hainanensis were compared and the species found conspecific as the structure of penis is very peculiar according to the cap-shaped apical lobe and very different from other species of the genus. Diagnostic characters mentioned for T. hainanensis in the original description (Ran & Liang, 2006) are only the coloration of coryphe (vertex) and the number of apical spines on hind tibia. These charactres are more variable in comparison with male genitalia and may be treated as interspecific variation between the island populations. Finally both names were mentioned from Hainan ( Zhang & Chen 2012) which also confirms our point of view.

The genus Thabena is Indo-Malayan and currently groups 14 species distributed in China, Indonesia, Malaysia, Philippines, Singapore, Taiwan, and Thailand ( Gnezdilov, 2009, 2013b). Thabena brunnifrons (Bonfils, Attié et Reynaud, 2001) described from Réunion was probably imported from Asia to this island ( Gnezdilov, 2009) and Thabena fissala (Fieber, 1876) described from Portugal by Fieber might be due to an error of locality ( Gnezdilov et al., 2011). As it could have been expected, this genus is now found also in northern Vietnam.
