| abstract | A survey of the small mammals of Nepal from September 1965 to January 1966 yielded 14 species of chiggers, 6 new, belonging to the genus and subgenus Leptotrombidium. The new species, L. (L.) dooleyi ex field mouse; L. (L.) mitchelli ex Rattus nitidus, Suncus murinus caerulescens; L. (L.) murphyi ex R. rattus, R. r. tistae, R. r. brunneus, R. r. brunneusculus; L. (L.) narayanshahi ex Bandicota bengalensis, R. r. brunneus, R. r. brunneusculus; L. (L.) rowanae ex R. r. brunneus, R. r. brunneus, R. r. brunneusculus; L. (L.) rowanae ex R. r. brunneus, R. r. brunneusculus; and L. (L.) worthi ex R. r. brunneusculus are described and illustrated. L. (L.) macacum (Womersley, 1952) and L. (L.) puta (Womersley, 1952) are redescribed and illustrated. The synonymy of subgenus Ericotrombidium Vercammen-Grandjean & André, 1966 with subgenus Leptotrombidium Nagayo et al., 1916, and species L. (L.) pumile (Traub et al., 1958) with L. (L.) fulleri (Ewing, 1945) is proposed. A key is given to the 14 species discussed. Host, altitude and habitat distribution of the Leptotrombldium species are presented in tabular form (TABLE 2 & 3). |
