Orthalicus powissianus niveus Preston, 1909 Figs 17i-ii, L14iii

Orthalicus powissianus var. niveus Preston 1909: 512.

Type locality.

"Jimenez, Rio Dagua, West Colombia".

Label.

"Jimenez Rio Dagua / 1600 ft. Colombia", in Preston’s handwriting.

Dimensions.

Not given. Figured specimen H 65.2, D 31.3, W 7.2.

Type material.

NHMUK 1909.8.18.85, holotype, M.G. Palmer leg., ex Preston.

Remarks.

Preston mentioned "taken with the animal alive", from which may be inferred that he had only one specimen at hand. The specimen located is thus the holotype; the top is slightly damaged. The taxon is here figured for the first time. The current systematic position at species level follows Richardson (1993: 125).

Current systematic position.

Orthalicidae , Sultana (Methorthalicus) powisiana (Petit de la Saussaye, 1843).
