Hassan, Muhammad Asghar & Xing, Jichun, 2024, A new species of the leafhopper genus Satsumanus Ishihara (Hemiptera: Cicadellidae: Deltocephalinae) from China, Zootaxa 5443 (2), pp. 263-272 : 265

Key to species (males) of Satsumanus (modified from Rajgopal et al. 2023)

1. Phragma forming a pair of large roundedly squarish or rectangular plates.......................................... 4

- Phragma not forming any large roundedly squarish or rectangular plates.......................................... 2

2. Aedeagal processes subequal to or slightly shorter than gonopore-bearing shafts and bases of processes close to shafts in lateral view ( Fig. 29 )........................................................................................ 3

- Aedeagal processes nearly twice the length of gonopore-bearing shafts and bases of processes well separated from shafts in lateral view ( Fig. 14 ).................................................................. S. discedens sp. nov.

3. Aedeagal processes subequal to aedeagal shafts in lateral view ( Kim & Jung 2020: fig. 2G; Fig. 29 ), shafts and processes almost parallel in ventral view, each shaft without subapical curved hook-like lamellar expansion over gonopore in lateral view ( Kim & Jung 2020: fig. 2F; Fig. 28 ).................................................................. S. satsumae

- Aedeagal processes shorter than aedeagal shafts in lateral view ( Rajgopal et al. 2023: fig. 2H), shafts divergent and processes almost parallel in ventral view ( Rajgopal et al. 2023: fig. 2I), each shaft with a subapical curved hook-like lamellar expansion over gonopore in lateral view ................................................................ S. chajingensis

4. Basal processes shorter than aedeagal shafts in lateral view ( Linnavuori 1960a; fig. 43b) .................... S. breviceps

- Basal processes longer than aedeagal shafts in lateral view ( Linnavuori 1960b: fig. 17d)............................. 5

5. Basal processes of aedeagus thick basally and constricted medially, with inwardly produced angulate leaf-like extension at apex in ventral view (Eyles & Linnavuori 1973: fig. 8a)................................................. S. ornatellus

- Basal processes of aedeagus uniform thin and gradually tapered towards apex, without angulate leaf like inward extension at apex ( Linnavuori 1960b; figs 1 b&c)..................................................................... 6

6. Socle rectangular and robust in ventral view; aedeagal shaft wide throughout, tapered only at apex; basal process outer lateral margin curvilinear, not keeled at subapical position ( Linnavuori 1960b: fig. 17c)........................ S. rubrinervis

- Socle rectangular and not robust in ventral view; aedeagal shaft slender throughout; basal process keeled subapically, abruptly tapered afterwards ( Linnavuori 1960b; fig. 17b)................................................. S. multispinosus
