Contribution to the knowledge of carabodid oribatid mites (Acari, Oribatida, Carabodidae) of the Philippines

摘要

Nine species from six genera of the family Carabodidae are recorded in the Philippines. The species Diplobodes kanekoi, Gibbicepheus latohumeralis and Yoshiobodes (Y.) irmayi are recorded for the first time in the Philippine fauna, and Austrocarabodes bituberculatus, Gibbicepheus micheli and G. rugosus are recorded for the first time in the Oriental region. One new species of the genus Cavaecarabodes is described, C. polilloensis sp. nov., which is similar to C. orientalis (Mahunka, 1987) and C. hauseri (Mahunka, 1989), but differs from both by the larger notogastral concavity and remoteness of notogastral setae c from the anterior margin of the notogaster. It differs further by the absence of notogastral tubercles on the hump-structure (present in C. orientalis) and the presence of well-developed interlamellar processes (indistinct in C. hauseri). A supplementary description of Bathocepheus manguiati (Corpuz-Raros, 1979) is presented. Identification keys to known species of Cavaecarabodes and Bathocepheus are provided.
