30. Bostryx bilineatus (Sowerby, 1833)

Distribution: Guayas, 17 km WNW Progreso [= Gómes Rendón] ( FLMNH 139140)*; 11 km W Progreso ( FLMNH 139079)*; 1 km ENE Progreso ( FLMNH 139047)*; 5 km NNE Progreso ( FLMNH 139049)*; 4 km N Palmar ( FLMNH 139078)*; 5 km N Palmar ( FLMNH 139056)*; 4 km N Monteverde ( FLMNH 139077)*; 3 km E Zapotal ( FLMNH 139106)*; 9 km S Manglaralto ( FLMNH 139114)*; Santa Elena ( RMNH); 11.2 km NE Santa Elena ( FMNH 106230)*; 32 km NE Santa Elena ( FMNH 106153)*;. Manabí, Manta ( FMNH 125507, 125216); 11 km WNW Jipijapa ( FLMNH 139038)*; 1 km S Ayampe ( FLMNH 139048)*.

Remarks: There are according to the GNS two places named Progreso in Guayas province [01° 46' 00" S 079° 45' 00" W and 01° 53' 00" S 079° 52' 00" W respectively]. Given the record for Zapotal, it is most probably that a place named Gómes Rendón was meant [02° 24' 00" S 080° 22' 00" W] for which the GNS lists as a variant name Progreso.

31.? Bostryx ceroplastus (Pilsbry, 1896)

Type locality: Peru, Río Marañon, Balsas. Lectotype ANSP 25468 ( Breure 1979).

Distribution: Tungurahua, 32 km SE Ambato ( FMNH 106156).

Remarks: This is a species from the eastern slopes of the Andes in northern Peru and its disjunct distribu-tion—both geographically and in altitude—makes a confirmation of this record necessary.
