First description of the male caste of the Himalayan endemic ant Lasius alienoflavus Bingham, 1903 (Hymenoptera: Formicidae), with re-description of the female and queen castes
The present paper provides a description of the male caste and re-description of the worker and queen castes of the poorly known ant species Lasius alienoflavus Bingham, 1903. This species has hitherto been reported only from the Himalayas, and the present data are also based on specimens collected in the north-western part of the mountain range. Likewise other Himalayan ants, this species also shows restricted distribution, which suggests a rather high degree of endemism (45%) of this group in the Himalayas.
