| abstract | Two new species of oribatid mites of the genus Allogalumna (Oribatida, Galumnidae) are described from litter and soil materials of Sumatra, Indonesia. Allogalumna indonesiensis sp.n. is morphologically most similar to A. borhidii Balogh & Mahunka, 1979, A. quadrimaculata (Mahunka, 1988), A. rotundiceps Aoki, 1996 and A. plowmanae Balogh & Balogh, 1983; however, the new species differs by having densely ciliate bothridial heads, larger body size and absence of median pore. Allogalumna paranovazealandica sp.n. is morphologically most similar to A. novazealandica Hammer, 1968; however, the new species differs by the shorter body length and barbed and curving postero-laterad bothridial setae. The genus Allogalumna is recorded for the first time in the Indonesian fauna. |
