Type locality.

[Colombia] "Andes of Columbia".

Type material.

NHMUK 20140082, lectotype ( Breure and Schouten 1985: 29) (Cuming coll.).

Diagnosis.

Shell sculptured with a dense pattern of fine spiral lines, coloured with pairs of yellow, irregularly waving and zigzag, longitudinal bands bordered with dark brown on the right side.

Dimensions.

Shell height 56.9, diameter 32.8 mm.

Distribution.

Colombia. Ecuador, Prov. El Oro, 10.2 km W Pinas (UF 26616); Prov. Pichincha, Milpe (ANSP 170727); ibid., San Nicolás (RBINS); Prov. Tungurahua, Topo (FMNH 86649).

Ecoregion.

Eastern Cordillera real montane forests [NT0121], Northwestern Andean montane forests [NT0145].

Remarks.

Breure and Ablett (2015) noted that the lectotype, for which the dimensions are given above, is probably not full-grown. Their figures L2 i–ii illustrate Orthalicus bensoni (Reeve, 1849); this error is now redressed by figuring the correct shell. Also the specimen of Zebra fulgur Miller, 1878 was subadult as Miller gave the shell height as 50 mm. Cousin (1887) mentioned a specimen from San Nicolás, which was located in the RBINS collection. In the same collection a specimen was found with locality “Cabiloña, montaña / près Ambato"; we have been unable to find this locality in modern gazetteers.
