2005 Paranyctoides sp. ; Archibald and Averianov 2005: figs. 2F, 3G. Referred specimens: ZIN 85044, left M1 (CBI−117, 1998); ZIN 85078, left dentary fragment with p2 and alveoli for c, p1, and p3–4 (CBI−117, 1998); ZIN 85294, left m1 or m2 (CBI−117, 1999). From locality CBI−117, Dzharakuduk, Kyzylkum Desert, Uzbekistan; Aitym Formation, Upper Cretaceous (upper Turonian–Coniacian?).
Description.—See Averianov and Archibald (2003: 178–180).
Comments.—We now consider ZIN 85044, a left upper molariform tooth previously interpreted as an M1 of Paranyctoides sp. (Archibald and Averianov 2001: fig. 4) or Paranyctoides sp. cf. P. aralensis (Averianov and Archibald 2003: 178) to be a zhelestid DP5 ( Archibald and Averianov 2012). It is similar to the DP5s of several zhelestid taxa, and differs from the upper molars of Paranyctoides in its beveled labial margin, less protruding parastylar lobe, and more expanded labial cingula.
Although the M1 from the Aitym Formation (ZIN 85044) is structurally very similar to the M1 of P. quadrans (CCMGE 7/11758), it is more robust, less constricted at the conular region, and bears more expanded lingual cingula. With the limited sample of upper molars of Paranyctoides from Dzharakuduk, it is impossible to determine the taxonomic significance of these differences. The lower molar from the Aitym Formation is likely an m1 because of the relatively large difference between trigonid and talonid widths. Otherwise, this specimen is indistinguishable from the lower molars of Paranyctoides from the Bissekty Formation.
