Bostryx elatus

Distribution of Bostryx elatus include Peru.^[2]

This species was originally described from ‘Pichicna, 2 leagues from Icucha […] between Mayoc and Huanta’.^[2] This points to a region between Mayoc in Huancavelica Region, 2200 m, 12°48’40’S 074°23’07’W and, most probably Huanta [misspelling for Huantana], 3000 m, 13°46’01’S 073°37’13’W in Apurímac Region.^[2]

Fritz Haas (1955)^[3] reported on specimens collected near Mayoc and Locroja [3700 m, 12°41’S 074°26’W] in Huancavelica Region and added Palmira [2300 m, 13°35’19’S 073°11’25’W] in Apurímac Region.^[2]

Beure (2010)^[2] reported on specimens collected ca. 55 km North-West of Mayoc.^[2]

Haas (1955)^[3] also noted that the colour pattern varied more in the specimens from near Mayoc and Locroja.^[2] The variety in patterns, from uniformly greyish-white to uniformly streaked at irregular intervals, is also observed in material collected by Breure (2010).^[2] The aberrant pattern noted by Haas, viz. streaks with ‘lateral, triangular appendages that tend to be arranged in spiral rows’ has been observed in a single shell from the series examined by Breure (2010).^[2]
