Bulimus melanocheilus Nyst, 1845 Figs 4 A–B, 4i

Bulimus melanocheilus Nyst 1845b: 149, pl. 2 fig. 3.

Type locality.

“l’Amérique mériodionale, au Pampas".

Label.

"Amerique mériodionale / (Pampas) / Pampaijacu", in Nyst’s handwriting.

Dimensions.

"longeur de 80 millimètres sur 35 de largeur"; lectotype H 78.5, D 36.6, W 6.2.

Type material.

RBINS/MT2361, lectotype (design. n.), ex Nyst.

Remarks.

The specimen is accompanied by a label of Nyst, dated 1874, and marked "type Nyst". Nyst (1845b) writes "cette belle coquille", but this is here-following ICZN Recommendation 73F-not interpreted as a holotype; the specimen is now designated as lectotype. The locality " Pampaijacu" (or Pampayacu) is found only in Peru, both in Dept. Lima and Dept. Huánuco. Since the former is at 3800 m and beyond the altitudinal range known for this genus (0-2300 m; Breure 1979), the type locality is probably Pampayacu in Dept. Huánuco [09°33'S, 75°54'W, 1150 m].

Current systematic position.

Megaspiridae , Thaumastus (Thaumastus) melanocheilus (Nyst, 1845).
