The finding of holotype and redescription of Cottus microstomus Heckel 1837 (Cottidae)


The holotype of Cottus microstomus Heckel 1837 had been considered lost for a long time; the holotype of C. microstomus was found in the ichthyological collection of the Natural History Museum, Vienna. This paper presents description of the found holotype, together with sculpins from Vistula River (Baltic Sea basin) and Dniester River (Black Sea basin). The type locality of C. microstomus is an area near the City of Kraków, Poland. The holotype and non-type specimens from Vistula and Dniester Rivers have extended body with depth 16.1–21.1% (19.9% in holotype) SL; caudal peduncle length 12.0–16.4% (14.2%) SL, its depth 2.5–3.0 (3.0) times its length; the head large, 28.6–34.9%, mean 32.2% (30.7%) SL; a well-developed groove on the head in 32% specimens from the Vistula system and all specimens from Dniester River; eye horizontal diameter 18.5–24.2% (23.8%) HL; interorbital space narrow, its width 1.5–2.0 (1.5) times its eye diameter; mouth small, lengths of the upper and lower jaws 28.4–37.0% (36.6%) SL; first dorsal-fin rays 6–8 (8); second dorsal dorsal-fin rays 16–19 (19); anal-fin rays 12–15 (15); pectoral-fin rays 13–16 (16). Cottus microstomus differs from other European species of Cottus by the following combination of characters: narrow caudal peduncle, its depth 2.5–3.0 of its length; no hump behind head, and dorsal profile smoothly between head and back; mouth small with upper jaw extending below anterior margin of eye; genital papilla lobular in males; bony prickles (modified scales) on skin commonly absent on entire body; lateral-line canal complete reaching to caudal-fin base, with 33–35 (rarely 31) pores.
