Cephennodes longilinguis species group

Diagnosis. Aedeagus in lateral view with subcylindrical apical lateral projection and one tongue-like subapical dorsal projection; in ventral view apical structures composed of apical lateral projections and subapical dorsal projection symmetrical and much narrower than basal capsule; parameral apices not discernible and asetose.

This group includes two previously described species distributed in Yunnan, C. brachylinguis Jałoszyński, 2007a and C. longilinguis Jałoszyński, 2007a . Two more species are described below.

Key to males of Cephennodes (Fusionodes) longilinguis group

1 In lateral view, distal margin of capsular region of median lobe convex and rounded, and dorsal margin of subapical dorsal projection weakly and evenly convex..................................................... C. linguatus sp. nov.

- In lateral view, distal margin of capsular region of median lobe with variously deep emargination or indentation, and dorsal margin of subapical dorsal projection weakly sinuate, concave or straight......................................... 2

2 In lateral view, subapical dorsal projection much longer than apical lateral projection, and distal margin of capsular region of median lobe with deep U-shaped emargination; in ventral view, distal region of aedeagus almost as long as wide.......................................................................................... C. linguatoides sp. nov.

- In lateral view, subapical dorsal projection about as long as apical lateral projection, and distal margin of capsular region of median lobe with shallow and broad emargination or with subtriangular indentation; in ventral view, distal region of aedeagus much longer than wide................................................................................. 3

3 In dorsal view, subapical dorsal projection at base only slightly wider than 1/3 of median lobe at the same level and more than twice as long as broad; in lateral view, distal margin of capsular region of median lobe with subtriangular indentation................................................................................... C. brachylinguis Jałoszyński

- In dorsal view, subapical dorsal projection at base much wider than 1/3 of median lobe at the same level and less than twice as long as broad; in lateral view, distal margin of capsular region of median lobe with shallow and broad evenly arcuate emargination................................................................... C. longilinguis Jałoszyński
