Type material.
Holotype CUMZ 12146/1 (Figs 37D View Figure 37 , 40A View Figure 40 ), 9 Apr. 2000, coll. C. Sutcharit, P. Tongkerd, S. Panha. Measurement: shell height 6.0 mm, shell width 4.6 mm and 5¾ whorls. Paratypes CUMZ 12146/2-8 (7 shells; Figs 37E View Figure 37 , 40B View Figure 40 ) and NHMUK 20210338 (2 shells), same data as holotype.
Type locality.
Khao Ok Talu, Mueang Phatthalung District, Phatthalung Province, Thailand, 7°37'32.2"N, 100°05'28.5"E, 120 m amsl.
Diagnosis.
Shell ovate; last whorl ca. three quarters of shell height. Apertural lip thickened but not expanded. Parietal tooth sharp, tooth-like; columellar tooth sharp, triangular shaped. Both anterior and posterior canals widening like keyholes bordered by its respective tooth and a small bulge of the outer lip.
Differential diagnosis.
Pupina latisulci sp. nov. can be distinguished from all other species in the P. aureola species group from mainland Southeast Asia by having both anterior and posterior canals widening like keyholes that are bordered by its respective tooth and a small bulge of the outer lip.
Description.
Shell height 4.0-4.5 mm; shell width 5.9-6.3 mm. Shell ovate, solid, semi-transparent, whitish to pale brown, devoid of prominent sculpture on glazed smooth surface. Apex obtuse. Growth lines on shell surface inconspicuous. Whorls 5¾, last whorl large (ca. three quarters of shell height). Spire angle ca. 90°, slightly extended. Sutures slightly impressed, but shallow. Aperture circular; lip thickened (ca. 0.1-0.2 mm wide and 0.1-0.2 mm thick) with paler colour, not expanded. Parietal callus not sharply defined and somewhat thickened with paler colour. Peristome interrupted by two canals; posterior canal ca. 0.6 mm long, 0.4 mm at its widest, continuing obliquely to form a narrow groove that widens upward like a keyhole; bordered by parietal tooth and more thickened lip appearing as a small bulge. Anterior canal slit-like continuing horizontally ca. 0.7-0.8 mm, widening towards outer margin like a keyhole, bordered by columellar tooth and more thickened lip. Parietal tooth sharp, thickened (ca. 0.6 mm long, 0.4 mm at its widest and 0.2 mm thick), tooth-like. Columellar tooth thickened (ca. 0.6 mm long, 0.9 mm at its widest and 0.2 mm thick), sharp, triangular shaped. Umbilicus closed. Operculum unknown.
Etymology.
The specific epithet Pupina latisulci is derived from the Latin word latus meaning wide and sulci [plural form of sulcus] meaning furrow or groove, which describes the widening of both anterior and posterior canals in the new species.
Distribution.
This new species is found from Phatthalung Province, southern Thailand.
