Canadaphis mordvilkoi Kononova, 1976 Material. Neotype PIN 3311 /2311, Russia: Krasnoyarskiy Krai: Taimyrsky (Dolgano-Nenetsky) District: Taimyr Peninsula: right bank of the Maimecha River in 3 km upstream from its confluence with the Kheta River (a left tributary of the Khatanga River), Yantardakh Hill (Yantardakh). Emended diagnosis. Antennal segment III shorter than the following ones. Vein Rs arising from pterostigma distally. Segment I of hind tarsi with five setae. Cauda long and rounded with many long hairs. Redescription. Body elliptical in outline, 1.08–1.12 in length. Head length—0.12, width—0.33. Epicranial suture reaches approximately the same height as the anterior edge of compound eyes. Lateral sutures depart from the edge of ocelli and connect with each other and with the epicranial suture. Compound eyes large— 0.09–0.1 in diameter, and in contact with the posterior part of antennal base. Triomatidium poorly distinguished (Fig. 2. d). Three ocelli visible, one on ventral side located centrally, above the level of the antenna base, two other on the dorsal side at the base of the antennae. Antennae six–segmented, slender, 0.48–0.50 in length (Fig. 2. a). Length of the individual segments: I—0.03, II—0.04–0.05, III—0.07, IV—0.08–0.1, V—0.11–0.13, VI—0.13–0.14. The terminal process short relative to basis. On segment VI oval rhinarium visible (Fig. 2. c), 0.02 in length. A rhinarium visible also in apical part of the third and fifth segment. Only apical part of rostrum visible (0.12 in length) (Fig. 2. b), reaching almost middle coxae. Apical segment blunt, similar in length (0.04) to the preapical one (0.03). There are four short setae on the apex of rostrum. Thorax 0.39 in length. Scutum convex, wider than long. The front margin of mesosternum slightly rounded with a small concavity in the middle, lateral arms narrow. Legs rather short. Coxae with single, short setae. Femora with sparse and short setae. On the tibiae setae longer and distinct, running in rows along the entire length. Segment I of ...
