Anisyutkin, Leonid N. & Yushkova, Olga V., 2017, New data on cockroaches of the subfamily Epilamprinae (Dictyoptera: Blaberidae) from India and Sri Lanka, with descriptions of new species and the genital complex of Aptera fusca (Thunberg, 1784), Zootaxa 4236 (1), pp. 41-64 : 43

Key to the Epilamprinae genera from South India and Sri Lanka

(the females of Rhabdoblatta Kirby, 1903 and Rhabdoblattella Anisyutkin, 2000 cannot be identified without the corresponding males)

1. Tibial spines well developed ( Fig. 9 A)................................................................... .. 2

- Tibial spines poorly developed ( Fig. 3 C, D).............................................. Aptera Saussure, 1864

2. Hind metatarsus distinctly shorter than other segments combined; spines along the lower margin absent, substituted by long and flexible hairs.....................................................................................10

- Hind metatarsus slightly shorter or longer than other segments combined; spines along the lower margin present or absent, never substituted by hairs...............................................................................3

3. Euplantula along the lower margin of hind metatarsus large, occupying more than a half of the metatarsus length........ 4

- Euplantula along the lower margin of hind metatarsus small, apical.............................................. 7

4. Tegmina present, not reduced to the lateral flaps.......................................... Morphna Shelford, 1910

- Tegmina reduced to the lateral flaps or absent...............................................................5

5. Tegmina present as the lateral flaps.......................................................................6

- Tegmina absent.......................................................... Indoapterolampra Anisyutkin, 2014

6. Wings present as the lateral flaps, well visible............................ Opisthoplatia Brunner von Wattenwyl, 1865

- Wings absent or completely hidden under the tegmina................................ Placoblatta Bey-Bienko, 1969

7. Hind metatarsus with two distinctly unequal rows of spines along the lower margin; sexual dimorphism strongly expressed: males with the tegmina and wings completely developed, females without wings, with the tegmina being reduced to the lateral flaps or absent............................................................. Calolamprodes Bey-Bienko, 1969

- Hind metatarsus with two more or less equal rows of spines along the lower margin; sexual dimorphism varies.......... 8

8. Sexual dimorphism is well marked: males with the tegmina reaching the 6th abdominal tergite and wings reduced, females with the tegmina and wings completely absent; hypandrium with the right caudal side broadly excavated; caudal margin of concavity curved, forming a distinct tooth........................................ Princisola Gurney & Roth, 1976

- Sexual dimorphism is poorly marked: both sexes with the tegmina and wings surpassing the abdominal apex or shortened ( Fig. 4A ); hypandrium of a different type .......................................................................9

9. Hypandrium with a distinct median tooth directed upward ( Figs. 5 F, G, 6H, I, m.t.)...... Rhabdoblattella Anisyutkin, 2000

- Hypandrium without a median tooth.................................................. Rhabdoblatta Kirby, 1903

10. Tegmina with an obsolete venation, CuP reduced.......................................... Thorax Saussure, 1862

- Tegmina with a distinct venation, CuP present......................................... Phlebonotus Saussure, 1862
