abstract (from publication):
Loricaria holmbergi, new species, from Aguas Calientes creek, northwestern highlands of Argentina, differs from all known species of the genus by the following combination of characters: anterior abdominal complex naked in the pectoral girdle region, thoracic length 12,5-17,4 % of SL; snout length 36,6-55,6 % of HL; number of plates in the lateral series 31-34; fused plates of the lateral series 12-15; upper unbranched caudal ray extended in a filament; pectoral spine thickened; postorbital notch moderately developed; and distinctive color pattern with small rounded and vermiculated dark spots, mainly over the sides and dorsal region of the head. Aguas Calientes is a complex of thermal waters, that because of its connection with other streams is the most diverse among the world’s thermal environments.
