Genus Scutalus Albers, 1850

Remarks: Breure (1979) placed Thaumastus umbilicatus Miller, 1879 (type locality: Prov. Loja, Catamayo, 2000–3000 ft.) under Nomina inquirenda, doubtfully suggesting that it might be a Scutalus .

Subgenus Scutalus (Vermiculatus) Breure, 1978

Type species: Bulimus bicolor Sowerby, 1835 . Distribution: Bolivia, Peru, Ecuador.

99. Scutalus (Vermiculatus) aequatorius (Pfeiffer, 1853)

Type locality: Mountain Schinchulagua. Lectotype BMNH 1975377 ( Breure 1979).

Distribution: Chimborazo, Cerro Chanchalahua, a foothill of Cerro Chimborazo ( BMNH 1975178/1 paralectotype); “Chimborazo” ( ZMZ 512209); Cotopaxi, Cerro Cotopaxi ( ZMB); Napo , Antisana ( FMNH 124573; MCZ 193333; ZMB); Pastaza, Cerros de Abitagua ( FMNH 129020); “Quito” ( CMC C11763, ZMH 7625).

100. Scutalus (Vermiculatus) anthisanensis (Pfeiffer, 1853)

Type locality: Mountain Anthisana. Lectotype BMNH 1975372. Bulimus cotopaxensis Pfeiffer, 1853 (type locality: Mountain Cotopaxi, lectotype BMNH 1975370) and Bulimus subfasciatus Pfeiffer, 1853 (type locality: Anthisana, lectotype BMNH 1975368) are considered synonyms, following Weyrauch 1967: 385 [see Breure 1978: 185].

Distribution: Chimborazo, Cerro Altar ( ZMB); Cotopaxi, Cerro Cotopaxi ( BMNH 1975371/1 paralectotype); Sigchos ( RMNH); Napo , Cerro Antisana ( BMNH 1975373/1 paralectotype of Bulimus anthisanensis Pfeiffer ; BMNH 1975369/1 paralectype of Bulimus subfasciatus Pfeiffer ; ZMB); Pichincha, Cayambe ( BMNH); San Francisco ( HMNH)*. “Quito” ( CMC C11762; ZMZ 512211, as B. subfasciatus Pfeiffer ). “ Ecuador ” ( ZMZ 512218, 512219; ZMZ 512213, as B. subfasciatus Pfeiffer ; ZMZ 512228, as B. cotopaxiensis Pfeiffer ).

Remarks: As Cerro Cotopaxi forms the cross of intersection of the provinces of Cotopaxi, Pichincha and Napo , we have arbitrarily attributed the locality to Cotopaxi, not knowing on which slope the type material was taken.

101. Scutalus (Vermiculatus) cousini (Jousseaume, 1887) Type locality: “Concha”. Holotype MNHN.

Distribution:? Morona-Santiago, Conchay ( MNHN). Remarks: Conchay is the only name that turns up in the GNS, that is closely resembling the original locality.

Scutalus sp.

Distribution: Azuay, Paute ( FLMNH 151259); Pichincha, near Pucará ( HMNH).
