5. Jansenia tetrastacta (Wiedemann, 1823)

Cicindela tetrastacta Wiedemann, 1823 Jansenia tetrastacta delhiensis Matalin & Anichtchenko, 2012 new synonymy

The subspecies J. t. delhiensis Matalin and Anichtchenko, 2012 was described on the basis of 17 specimens collected in Central Ridge Reserve Forest (New Delhi City ). The main features distinguishing it from the nominotypical subspecies were a lack of or indistinct small middle spots on the elytra, unicolored pale inner surface of hind femora, and more transverse labrum in males, i. e. 1.7–2.3 (1.9) times as wide as long in J. t. delhiensis compared to 1.6–1.8 (1.7) times as wide as long in J. tetrastacta s. str. The study of additional material, and re-study of type series of J. t. delhiensis, established that these characters are highly variable, and are found throughout other populations ( Figs 12-14). New synonymy is proposed here .
