Shear, William A., Richart, Casey H. & Wong, Victoria L., 2020, The millipede family Conotylidae in northwestern North America, with a complete bibliography of the family (Diplopoda, Chordeumatida, Heterochordeumatidea, Conotyloidea), Zootaxa 4753 (1), pp. 1-78 : 23

Ovaskella , new genus

Type species: Ovaskella ovaskae , n. sp.

Diagnosis: Related to Calityla . Both species in this genus have thin, acute anterior gonopods and rather uncomplicated posterior gonopod coxites, which have a single branch; this is like the preceding genus, but very much smaller, and enveloped in two fimbriate wings (the lateral wing much reduced in the type species). The coxite has a pore at the base of this branch, visible with secretion exuded in Fig. 88 of O. ovaskae , n. sp., but obscured by recalcitrant debris in Fig. 101 of O. sinuosa , n. sp..

Etymology: Kristiina Ovaska of British Columbia, Canada, has collected many valuable millipede specimens which she generously has shared with the authors and others. We take the first part of her surname and use the diminutive suffix -ella, as in Bollmanella .
