Zavrelimyia Fittkau ( Fig. 27 )

Head capsule narrow yellowish-brown, in some species partially dark in proximal part. Occipital margin darker with two thorn-like projections on ventral side ( Fig. 27 ). Mandible moderately curved with long apical tooth and large inner tooth. Mola expanded into large, blunt tooth ( Fig. 27 ). Dorsomentum without teeth. Ligula with 5 brown subequal teeth. Paraligula is bifid. Pecten hypopharyngis with 9–15 teeth, inner tooth and some middle teeth enlarged.

Remarks: Recently, Zavrelimyia includes formerly separate genus Paramerina as its subgenus ( Silva & Ekrem, 2016), which also has basal segment of maxillary palps subdivided always into 2 parts resembling some species of Ablabesmyia . However, arrangement of teeth on ligula in straight row should distinguish Zavrelimyia and Paramerina from Ablabesmyia (with concave row of ligula teeth). For more information see description of Ablabesmyia . Pupal exuviae material from the Tatra Mts. lakes was identified as Z. punctatissima ( Hamerlík & Bitušík 2008) .

Zavrelimyia was the second most abundant tanypod remain mostly occurring in the surface sediments of subalpine lakes.
