Lestes spp.

It is unfortunate that the above discussed circumstances happened to be revealed after publication of the amendments to Fraser’s key of the males of Indian Lestes spp. View in CoL by Kosterin (2019). Taken into account the above, couplet 10 of the revised Indian key is to be further updated as follows:

10. Males: paraprocts set close to each other and well seen from above; white pruinescence at the end of abdomen is present on S9–10. Females: cerci finger-like in dorsal view, narrowing apically; S10 mostly black. Smaller species, with hind-wing 20–21 mm and male abdomen 29–32 mm ................................................................... L. decipiens .

Males: paraprocts broadly diverging from bases and so not seen from above; white pruinescence at the end of abdomen confined to S10. Females: cerci conical in dorsal view, evenly tapering; S10 mostly pale. Larger species, hind-wing 23–32 mm and male abdomen 35–41 mm ......................................................................... L. dorothea .

In this version, the minimum length values were changed, as compared to Fraser (1933) and Kosterin (2019), in accordance to the specimens examined as follows: for L. dorothea : hindwing length from 24 to 23 mm, male abdomen length (without appendages) from 36 to 35 mm; and for L. decipiens : male abdomen length from 30 to 29 mm.
