Adalaria olgae

Until recently the small genus Adalaria was considered as a well-known. Therefore especially remarkable discovery of two new species of the genus in Kamchatka waters well distinguishing both externally and internally from all previously described species. Adalaria olgae is presently known only from the type locality in SE Kamchatka, but potential range includes both Commander and Kurile Islands. The species is especially easily detectable by the bright lemon-yellow colour, constant in all studied specimens.
