Etymology: The specific epithet is the past participle of the Latin verb foedare (to deform) and alludes to the strongly asymmetric male sternite VIII and aedeagus.
Description: 1.2–1.6 mm (abdomen extended), length of forebody 0.44–0.60 mm; males on average slightly larger than females. Colour of body dark-yellowish.
External characters as in Allotyphlus candicus ASSING, 2018, except for the slightly less pronounced microsculpture of the head.
♂: posterior margin of tergite VIII strongly convex; sternite VIII strongly asymmetric, with a pronounced postero-median impression and a posterior excision of distinctive shape (Figs 65–66); median lobe of aedeagus (Figs 67–70) approximately 0.25 mm long; ventral process strongly asymmetric.
♀: tergite VIII with weakly convex posterior margin; sternite VIII strongly convex posteriorly.
Comparative notes: Allotyphlus foedatus is reliably distinguished from the externally nearly identical A. candicus from East Crete by the completely different shape of the male sternite VIII, by the shape of the ventral process of the aedeagus, as well as by the shapes of the female tergite and sternite VIII. For illustrations of A. candicus see ASSING (2018b).
Distribution and natural history: This species is evidently quite common and widespread in West Crete eastwards to the Askifou plateau (to the west of Lefka Ori). The specimens were collected from soil in a variety of habitats, mostly in permanent and temporary stream valleys and on moist slopes with Platanus orientalis, chestnut, and oak trees, often with Rubus and/or fern undergrowth; the type locality is illustrated in Fig. 174. The altitudes range from 140 to 770 m. In two localities, they were found together with Kenotyphlus virgatus, in one with Cretotyphlus chanianus. The sex ratio is balanced.
