Ochrotrichia filiforma Flint 1972

Ochrotrichia (O.) filiforma

O. filiforma, new species, is probably most closely related to the following species, but may be easily recognized by the extremely elongate genital parts, especially the processes of the tenth tergum.

Tenth tergum with a slender middorsal spur; a black-tipped middorsal spine, slightly longer than spur; apically with left lobe scoop-shaped, produced ventrad, right lobe elongate, overlaying right process; with a very long, slightly sinuate process on right (probably displaced from normal position in type), second long process on right twisted underneath right lobe and arising from an ovate structure. Clasper very long, slender, apex rounded; apex and ventral margin with black peglike setae; midbasal ridge obsolete. Aedeagus long and threadlike.
