B. Hausdorf, 11 March 2000, measurements: D 51.6 mm, D2W51.0 mm, H 52.2 mm, da 50.75 mm, dh 50.75 mm)   . Paratypes: Colombia, Distrito Capital: Bogota´, forest near brook above Escuela Militar de Caballeria , 2750 m alt., 04 ° 419150N, 74 ° 019330W ( ZMH 4319 View Materials )   . Cundinamarca: La Calera 0.5 km towards Bogota´, farm Las Cabreras, Vereda San Rafael, Andean forest, 2830–2840 m alt., 04 ° 429300N, 73 ° 589200W ( ANSP; FLMNH; FMNH; NNM; SMF; UNAL; ZMH 4031 View Materials , 4063 View Materials ); Bosques de Torca, Andean forest , W slope, 2800 m alt., 04 ° 499180N, 74 ° 019070W ( ZMH 4331 View Materials )   . Boyaca´: Villa de Leiva, oak forest near Manantiales de Iguaque , W slope, 2600 m alt., 05 ° 419150N, 73 ° 289530W ( ZMH 4198 View Materials )   .

Shell ( Figure 8)

Conical; apex obtuse; teleoconch with coarse growth-wrinkles, without incised spiral striae; corneous; shining; subtranslucent; 4.25–5 moderately inflated whorls separated by a deep suture; body whorl slightly descending towards the aperture, basally flattened; aperture truncate-rounded, edentate; peristome neither expanded nor reflexed nor thickened; columellar margin slightly dilated, partly covering the narrow umbilicus. Shell measurements and ratios are listed in Tables I and II.

Diagnosis

Pupisoma costulata   differs from all other Pupisoma species   in the conical shell with more whorls, a flattened base, and coarse growth-wrinkles. In shell shape and size it is most similar to P. mediamericanum   .

Remarks

Pupisoma costulata   occurs sympatrically with P. comicolense   . The range of P. costulata   overlaps that of P. mediamericanum   , the conchologically most similar species.

Etymology

The species is named after its finely ribbed (Latin costulatus, used as an adjective) shell. Type locality

Colombia, Cundinamarca: La Calera 0.5 km towards Bogota´, farm Las Cabreras, Vereda San Rafael, Andean forest , N slope, 2840 m alt., 04 ° 429300N, 73 ° 589200W   .

Distribution ( Figure 13 View Figure 13 )

Pupisoma costulata   is known from Andean forests at 2600–2840 m altitude in the Departamentos Cundinamarca and Boyacá and the Distrito Capital in Colombia   .
