Key to Nevrorthus species

1. Fore wings not darker shading on the transverse veins ( Fig. 15 )................................................. 2

- Fore wings darker shading on the transverse veins ( Fig. 16, 17 )................................................. 3

2. Scape and pedicellus yellowish as flagellum, or very slightly darker ( Fig. 20, 25 ). Apex of the male 9th sternite deeply forked ( Fig. 14 ).................................................................................. N. iridipennis

- Scape and pedicellus strongly dark brown ( Fig. 19, 23, 24 ). Apex of the male 9th sternite unforked ( Fig. 13 ).... N. apatelios

3. Fore wings light dark shading on the transverse veins, hardly spread over the adjacent membrane ( Fig. 16, 18 ). Antennae with flagellum uniformly yellow or pale brown. Apex of the male 9th sternite deeply cloven on the midline ( Fig. 11, 12 )........ 4

- Fore wings intensely dark shading on the transverse veins, strongly extended over the adjacent membrane ( Fig. 1, 2 , 17 ). Antennae with light darker flagellum on the distal third. Apex of the male 9th sternite very slightly cloven on the midline ( Fig. 8 , 10 )................................................................................ N. reconditus n. sp.
