Breure, Abraham S. H. & Borrero, Francisco J., 2008, An annotated checklist of the land snail family Orthalicidae (Gastropoda: Pulmonata: Orthalicoidea) in Ecuador, with notes on the distribution of the mainland species, Zootaxa 1768, pp. 1-40 : 26-27

Genus Orthalicus Beck, 1837

Type species: Buccinum zebra O.F. Müller, 1774 . Distribution: West Indies, Venezuela, Guiana, Surinam, French Guyana, Brazil, Peru, Ecuador, Colombia, Panama, Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Belize, Mexico, USA.

Remarks: The species of this genus are generally very variable, with different colour forms and transitions between them. Strebel (1909) has made a useful revision, although this does not prevent that there are obviously quite some misidentifications in collections.

155. Orthalicus bensoni (Reeve, 1849)

Type locality: Banks of the Amazon. Syntypes BMNH 1975582, labelled “ Brazil ”. Distribution: Napo , Sarayacu (Pilsbry 1899: 148); Río Napo ( CMC C10806).

156. Orthalicus bifulguratus (Reeve, 1849)

Type locality: Andes of Colombia.

Distribution: El Oro, 10.2 km W Pinas ( FLMNH 26616)*; Pichincha, Río Pilatón (Pilsbry 1899: 143 mentions Pilaton Valley on the basis of specimens collected by Wolf); Tungurahua, Topo ( FMNH 86649).

157. Orthalicus maracaibensis (Pfeiffer, 1856) Type locality: Venezuela, Maracaibo.

Distribution: Guayas, Guayaquil ( ZMH 9883); San Juan (Pilsbry 1899: 140 mentions “ Ecuador, San Juan de la Costa” as locality for his colour form imitator. From among the many places named San Juan this is the only one located near the coast).

159. Corona pfeifferi (Hidalgo, 1869)

Type locality: Canelos.

Distribution: Pastaza, Canelos; Tungurahua, Topo ( ANSP 306620).

161. Corona regina (Férussac, 1823)

Type locality: Not given. Lectotype MNHN ( Simone 2006).

Distribution: “ Ecuador ” ( FLMNH 109375).

Remarks: The attribution of authorship and year of publication of this species has been confusing, but can be summarized as follows:

Helix regina Férussac, 1821: 40 [nomen nudum].

Helix regina Férussac, 1823 in Férussac & Deshayes, 1819 –1851: pl. 119.

not Helix regina Fér., Bowdich, 1823 : Pl. 8 Fig. 26 [= Liguus virgineus Linné, 1766 ; see Pilsbry, 1901: 165].

The confusion was probably due to the complex publication history of Férussac’s Histoire ... which was continued after his death by Deshayes; Kennard (1942) has sorted out the publication dates of the different volumes in which this work was issued. Helix regina was originally mentioned by Férussac in 1821, but not validly published according to the ICZN-rules. It was referred to by Simone (2006: 160) as Corona regina (Férussac in Bowdich, 1822).

162. Corona rosenbergi Strebel, 1909 **

Type locality: Not given.

Distribution: Orellana, Loreto (ANSP 195205). Remarks: This is the first precise locality for this species.
