We describe six new species in the genus L.: , , , , , collected from the Indian part of the Eastern Himalayas (West Bengal) and Northeast India. We provide a detailed morphological description of all six species along with photographic plates, distribution maps, and tentative conservation assessments. We also provide a dichotomous identification key for all the Indian species and discuss the newly described species in relation to those that are morphologically similar to them. Finally, we highlight the taxonomic collection challenges in the ecologically sensitive Eastern Himalayas and Northeast regions of India.
