Abstract
A list of identified oribatid mite taxa (Acari, Oribatida) from Capual, Luzon, Mindanao, Polillo, Samal and Samar Islands of the Philippines, including 54 species from 46 genera and 26 families, is presented; of these, 19 species, four genera and one family are recorded in this country for the first time. A new generic diagnosis for Drymobatoides (Mochlozetidae) is proposed. The taxonomic status of the mochlozetid genus Rykella is discussed, resulting in the proposal that Drymobatoides Jacot, 1936 is a senior subjective synonym of Rykella Balogh, 1962 (n. syn.) and in the following reassignments from Rykella: Drymobatoides asiaticus (Yamamoto and Aoki, 2000) n. comb., D. elamellatus (Berlese, 1916) n. comb., D. insignis (Balogh, 1962) n. comb. A new species of Drymobatoides from the Phillippines is described; D. boronganensis n. sp. differs from D. malabaricus (Clement and Haq, 1982) by the morphology of rostral, lamellar and bothridial setae, the length of the interlamellar seta, and the presence of a ventrodistal rectangular incision on leg femur II. An identification key to the seven known species of Drymobatoides is provided.
Highlights
This work is the final report for our study of the Philippine oribatid mites (Acari, Oribatida) based on a random set of previously unstudied materials, which were received in 2016 from the collections of the Museum of Natural History (University of the Philippines Los Baños)
Drymobatoides was proposed by Jacot (1936) with Drymobatoides mauritius Jacot, 1936 as type species
Material — Reported mites were collected from the following sites in the Philippines: Polillo Island, Quezon Province, Polillo Municipality: 3596; 3596 – Barangay Burdeos, 16.II.2007
Summary
This work is the final report for our study of the Philippine oribatid mites (Acari, Oribatida) based on a random set of previously unstudied materials, which were received in 2016 from the collections of the Museum of Natural History (University of the Philippines Los Baños). These materials come from the Capual, Luzon, Mindanao, Polillo, Samal and Samar Islands, where oribatids are insufficiently studied (e.g. Corpuz-Raros 1979, 2000, 2014; Corpuz-Raros and Gruèzo 2005, 2011). Drymobatoides was proposed by Jacot (1936) with Drymobatoides mauritius Jacot, 1936 as type species It comprises three paleotropical species (Subías 2004, updated 2016), including the type species of its two generic synonyms (=Pelokylla Clement and Haq, 1982, =Seychellozetes Mahunka, 1984). We explain why we consider the paleotropical genus Rykella to be yet another junior synonym, and provide an identification key to the seven known species of Drymobatoides
