fig. 7 [non fig. 9, ?11, 12 (= K. viridatus); non fig. 10
(= indet.)].
= Encrinuroides Reed; Mägi, Viira and Aru 1989 p. 66.
= 1990 Encrinuroides sp. nov.; Aru, p. 72.]. Its type specimen is GIT 389- 7 (t), a cephalon/head (an incomplete cranidium), and it is a 3D body fossil. Its type locality is Bed 3 Popovka section, which is in a Billingen shallow subtidal sandstone in the Leetse Formation of the Russian Federation.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. Pärnaste 2006 | Exoskeleton with comparatively flat middle lobe, and low palpebral fixigena; anterior portion of cephalon and genal area abaxial from the eyes curve steeply downwards. Glabella with equal L1 and L2, and symmetrically developed glabellar tubercles: 1L)2L)3L)4L1 -1, 4L2 -2 and the second anterior border tubercle lie in one curved line. Anterior cranidial border deeply inclined medially, bearing six symmetrically distributed tubercles. Librigenal border straight, with no inflation, bearing a few very low tubercles at the axial furrow; the very shallow anterior border furrow hardly distinguishes it from the prematurely short LP with low inflation and a few tubercles, developed on the broadest area, i.e. laterally. Rostral suture concave. Prominent fixigenal circumocular tubercles in regular ring around eye. Pygidium with five pairs of pleurae extending to the posterior border and united sixth pair appears as a convex ‘loop’ behind the axial lobe. The axis shows 12 rings with paired small tubercles anteriorly and a low, lens-shaped ridge breaking the rearmost rings sagittally. |
