DNA data.

See Table 2. On BOLD, U. rhododendronalis is represented by the BINs AAH7703 and ABZ6001.

Remarks.

We conclude from the data that none of the genitalia characters stated by Leraut (1996) for his subspecies are diagnostic: The shape of the valva apex and the size and extent of the protruding tooth ridge on the posterior phallus apodeme is variable in U. rhododendronalis (and in other species of the U. alpinalis species group); the number of cornuti ranges from four to six and is not fixed for any of the proposed subspecies. In the female genitalia, the width of the ductus bursae is variable and can be significantly influenced by the uptake of spermatophore(s) during copulation. One of the dissected females contained two spermatophores in its genital tract, indicating the possibility of multiple mating. Due to the absence of distinct morphological characters among the three clades, the two subspecies U. r. luquetalis and U. r. ventosalis, both described by Leraut (1996), are synonymised with U. rhododendronalis .
