Viraktamath, C. A. & Meshram, Naresh M., 2017, A review of the coelidiine leafhopper genus Mahellus (Hemiptera: Cicadellidae: Coelidiinae) with description of two new species from the Oriental region, Zootaxa 4258 (3), pp. 271-280 : 272

Key to species of Mahellus

1. Subgenital plate with posterior spine-like projection ( Fig. 44 ).................................... .. ungulatus sp. nov.

- Subgenital plate without posterior spine-like projection ( Figs 21 , 36 ; Nielson 1982: Figs 260, 267).....................2

2. Pygofer ventral process short, glabrous ( Fig. 18 ); aedeagal shaft robust, tapered apically with lateral processes broad and spinose ( Figs 22–24 )....................................................................... distanti Nielson

- Pygofer ventral process with dentate ventral margin ( Figs 33 , 41 ; Nielson 1982: Fig. 263); aedeagal shaft narrow, with thinner processes ( Figs 37 , 45 ; Nielson 1982: Fig. 261)..............................................................3

3. Subgenital plate truncate apically ( Nielson 1982: Fig. 260); style with apophysis not produced into a thin process but narrowed ( Nielson 1982: Fig. 259)............................................................... determinatus (Distant)

- Subgenital plate rounded apically ( Fig. 36 ); style with apophysis abruptly narrowed and produced into a thin process ( Fig. 35 )...................................................................................... ... cardoni sp. nov.
