Etymology: solovjevae: From the author: "The species has been named for my first ichthyology teacher Natalia Stepanovna".
Solovjeva (1911–2005). She was an associate professor and the head of the vertebrate department at Perm State University for more than 20 years. She was a talented teacher and cultivated active interest in fish in her students. Having named a species in honor of her, I expressed my deep gratitude to my teacher, whom I will never forget. June 13, 2011, will be N.S. Solovjeva’s 100th anniversary, and a lot of her students and colleagues will remember with thanks this charming woman, great teacher, and very modest and polite person.".

Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Σπόνδυλοι: 48 - 49. P 35–37, C 14 (2+ 5/6 +1), rad. pect. 4 (3 + 1); three of them are situated on the top and have notch and inter-radial fenestrae. Three pairs of the saber-like pleural ribs. Two asymphytous and distally hypural plates; rudimentary parhypurale. The mouth is terminal. The teeth are simple. The gill slit is oblique and travels to the 10th–13th P ray, its length is 12.8–13.8% SL; the length of the head (c) is 28.9–30.7% SL; the length wise diameter of the disk is 8.7–12.2% SL. The peritoneum is light-colored; the Cooperation Sea Sea, 990–2012 m (Ref. 89382).
Coloration : the living bodies of both holotypes are grey-lilac. This color becomes more saturated at the end of the body or the ends of the dorsal and anal fins. The caudal fin is dark blue. The pectoral fins are lightly colored at the bottom and central parts. Their ends are dark blue (sometimes in a form of wash-outs) both on the external and internal sides. The head is lightly colored. It has a slight yellowish or pinkish film (especially in the paratype) and small light blue spot on the frontal side at the back. The maw and throat before the disk are lilac-grey. The disk is light with the dark blue border around the periphery. The jaws are light blue. The pupil is grey and has a light blue border. The color of the paratype is mainly pink with little contrast between lilac and blue. The peritoneum in both samples is brown with a greenish tint (Ref. 89382).
