Shih, Hsien-Tzung, Liang, Ai-Ping & Yang, Jeng-Tze, 2009, The genus Jembra Metcalf and Horton from Taiwan with descriptions of two new species and the nymph of J. taiwana sp. nov. (Hemiptera: Cercopoidea: Aphrophoridae), Zootaxa 1979, pp. 29-40 : 31

Key to the species of Jembra Metcalf & Horton

1. Ventral process of pygofer apex narrowly truncate, outer margin distinctly angled in ventral view .......................... 2

- Ventral process of pygofer tapered from base to apex, apex acute, outer margin not angled in ventral view ............. 3

2. Pronotum with an anterior, central, nearly X-shaped dark marking; aedeagus with the base triangular, apex with pair of finger-like and obviously elevated processes ( Figs. 1 G, 1H) ................................................... inouyei (Matsumura)

- Pronotum without X-shaped markings as above; aedeagus with base triangular, apex with pair of finger-like and obviously declivous processes ( Metcalf & Horton, 1934: Plate 143: Figs. 136, 140) .................... brevistriga (Walker)

3. Smaller species, body length less than 9.0 mm; ventral process of pygofer with apex acute, not forked .................. 4

- Relatively large species, body length greater than 11.0 mm; ventral process of pygofer with apex forked ( Fig. 5 J) ... ............................................................................................................................................................. taiwana sp. nov.

4. Rostrum nearly extended to apex of middle trochanters; pronotum without obviously lateral carinae, median carina interrupted by some longitudinal wrinkles on the anterior margin ( Fig. 3 A); genital styles nearly triangular ( Figs. 3 K–L) … ................................................................................................................................................ kuanae sp. nov.

- Rostrum reaching beyond hind trochanters; pronotum with a distinct median longitudinal carina; genital styles nearly Y-shaped, with distinct inner and outer processes ( Liang, 1999: Fig. 6) ........................................ sinica Liang
