Calliteara pseudolairdae sp. n.

Calliteara pseudolairdae

Calliteara pseudolairdae


22-25mm, 33-35mm. In forewing fades this species is very similar to lairdae, though the most distal of the antemedial series of fasciae is more indistinct towards the costa so that this series as a whole appears to narrow at that point, and is overall slightly narrower. The lunule of the postmedial between M1 and M2 tends to be more acute and asymmetric in pseudolairdae. The male genitalia also indicate a relationship to lairdae, but the processes of the eighth tergite are more robust, closer together on a narrower base (more as in cinctata Moore from N. India), the ventral part of the valve is produced into a distinct spine distally (similar to that of lunulata Butler from Taiwan), and lacks a central transverse flange, and the aedeagus vesica is shorter, with far fewer and more robust spines.
