Maiestas, Distant, 1917

Shah, Bismillah, Naveed, Hassan, Webb, Michael D. & Duan, Yani, 2021, Taxonomic review of the grassland leafhopper genus Maiestas Distant (Hemiptera: Cicadellidae: Deltocephalinae: Deltocephalini) from Pakistan with description of a new species and two new records, Zootaxa 5060 (3), pp. 401-416 : 403

Key to species of Maiestas from Pakistan

Note. Maiestas setosa is excluded from the key due to the poor original description and figures. M. pruthii , described from Pakistan, is included but known only from Indian material (see under M. pruthii remarks) while two un-named species (see Maiestas spp. ) would also key out to this couplet.

1. Overall color dark brown; forewing with sub-basal and subapical irregular white transverse band ( Fig. 1A )..................................................................................................... M. albomaculata

- Color not as above ( Figs 2A , 3A )......................................................................... 2

2. Crown, face and thorax with black patches ( Fig. 2A–D ).............................................. M. maculata

- Crown, face and thorax without black patches............................................................... 3

3. Forewing with extra cross-veins, at least in clavus ( Fig. 7B )................................................... 4

- Forewing without extra cross-veins....................................................................... 5

4. Aedeagus with a large subapical ventral process ( Fig. 1E )............................................... M. indica

- Aedeagus with a short apical ventral process ( Figs 4J–L )............................................... M. pruthii

5. Aedeagus with pair of short lateral processes ( Figs 6G–H )........................................... M. trispinosa

- Aedeagus without lateral processes....................................................................... 6

6. Aedeagus in lateral view similar in width in distal half ( Fig. 4D )...................................... M. subviridis

- Aedeagus in lateral view evenly tapered from base to apex.................................................... 7

7. Style apophysis broadest sub-basally ( Fig. 5L ); aedeagal shaft in lateral view not sinuate ( Fig. 5H )............... M. tareni

- Style apophysis broadest at base ( Fig. 3F ); aedeagal shaft in lateral view slightly sinuate ( Fig. 3H ).............. M. sinuata
