Untere Palnis: Tandikudi, ca. 1500 m , nach Regen unter den obersten Steinen einer Mauer, IV.1927 . Two ♂ . The MHNG collection contains two specimens in alcohol (MHNG-ARTO-14461). Both specimens are broken. The labels in the vial containing them have “Tandikudi III.1927 Carl leg.”, “Tandikudi” and “ Diopsiulus III Tandikudi ” written on them respectively, indicating that the specimens are syntypes . There are also three microscope slide preparations of parts of syntypes : 1) a slide (MHNG-ARTO-14462) of the gonopods, first three legs and gnathochilarium; 2) a slide (MHNG- ARTO-14463) of gonopods; 3) a slide (MHNG- ARTO-14464) of the first three legs. The labels on the slides give the name as D. plumosus , although this has been altered by Carl to D. plumipes on the first slide. Stemmiulus plumipes (Carl, 1941) , Stemmiulidae
