Genus Neodurium Fennah, 1956

Neodurium Fennah, 1956: 513 .

Type species: Neodurium postfasciatum Fennah, 1956

Generic diagnosis

Vertex with apical margin subrectangulately convex, sides of frons shallowly grooved between eye and frontoclypeal suture. Frons longer than broad in middle line, median carina strongly developed in basal 3/4, sublateral carinae obscure. Clypeus ecarinate, convex. Pronotum with small pit beyond each side of median carina. Mesonotum slightly depressed, with median carina obscure. Tegmina with claval suture absent, M simple. Hind wings deeply incised on apical margin into two lobes. anal lobe absent; veins simple. Pro- and mesofemora compressed. Post-tibiae with a lateral spine near base and two large distal spines.

Female genitalia

Ovipositor with third valvulae stout, strongly convex, with apical margins tumid, bounding lenticular cavity when apposed.

Male genitalia

Aedeagus shallowly U-shaped, ventrally with two blade-like spines in middle, crossed and directed towards base of aedeagus. Genital styles triangular ( Ran et al., 2005).

Distribution P. R. China: Hubei, Guizhou, Yunnan.

Key to species of Neodurium Fennah

1 Aedeagus without any process on dorsal margin ( Ran et al., 2005: Fig.23) .......... N. flatidum Ran & Liang

- Aedeagus with processes near basal 1/3 of dorsal margin ( Figs.7 , 16 ; Ran et al., 2005: Figs.7 , 15 )..........2

2 The dorsal processes of aedeagus smaller, finger-like ( Fig.16 , Ran et al., 2005: Fig.15 )............................3

- The dorsal processes of aedeagus larger, fan-like ( Fig.7 ; Ran et al., 2005: Fig.7 ).......................................4

3 Aedeagus with only one dorsal process, forked at apex ( Ran et al., 2005: Fig.15 ); spinal formula of hind leg 8-19-2 ........................................................................................................ N. digitiformum Ran & Liang

- Aedeagus with a pair of dorsal processes ( Fig.16 ); spinal formula of hind leg 6-10-2................................ ..................................................................................................... N. duplicadigitum Zhang & Chen sp. nov.

4 Frons with submedian carina attaining lateral margins ( Fig.2 ); in dorsal view, the lobes of anal segment with lateroapical margin sharp ( Figs.5, 6 ); ventral hooks of aedeagus narrowing and tapering suddenly near apex ( Figs.7, 8 ); spinal formula of hind leg 8-13-2 ................ N. weiningensis Zhang & Chen sp. nov.

- Frons with submedian carina not attaining lateral margins, but enclosing an elongate-oval area ( Ran et al., 2005: Fig.2 ); in dorsal view, the lobes of anal segment with apical margin obtuse ( Ran et al., 2005: Fig.5 ); ventral hooks of aedeagus tapering apically ( Ran et al., 2005: Figs.7, 8 ); spinal formula of hind leg 8-18-2 ................................................................................................................................ N. postfasciatum Fennah
