Abstract
Haemaphysalis nepalensis sp. n., described herein, and H. aponommoides Warburton, the only known male of which is also described, are of exceptional interest owing to their primitive phylogenetic position in this genus. Both, excellent indicators of stepwise evolution among haemaphysalids, occur in the Himalayan highlands, which are within the general center of haemaphysalid distribution. I am grateful to Dr. Robert L. Fleming of the United Mission Hospital, Kathmandu, Nepal, for sending these fine specimens and for the following collecting notes. Mr. Glen Kohls of the Rocky Mountain Laboratory kindly read the manuscript and furnished specimens of H. aponommoides from Formosa for study. The localities in which these specimens were taken are in Ramechap District. Thodung (10,000 feet elevation) and Serping (10,800 feet elevation) lie just east and above Kimpti Khola, on a spur running directly towards Gauri Shankar peak. This is a region of heavy rhododendron and evergreen forest with barberry bushes in more open, grassy areas. Thodung and Serping have Swiss dairy installations where numerous herds collect, and swarm with leeches during wet weather. Rainfall is heavy and much vegetation grows above tree line, 12,000 feet elevation, in summer. Specimens of H. aponommoides were collected from a serow and from domestic cattle in this area.
