sp. nov.

Diplommatina godawariensis Budha & Naggs  sp. nov.


Figs 4BView Fig, 9EView Fig


Measurements (n = 5): SH 3.2–3.5 mm, SW 1.7–1.8 mm, Wh: 6.5–7.0; holotype: SH 3.3 mm, SW 1.8 mm, Wh 7.0. Dextral, penultimate and body whorl nearly equal in width. Constriction at the inner edge of PeP ( Fig. 9EView Fig). Two parietalis: Prt1 short and strong, Prt2 not very distinct, nearly attached to the sutural wall ( Fig. 4BView Fig 3View Fig). Two vertical palatalis, Vpt1 strong and runs along the constriction, Vpt2 short and small, difficult to distinguish, just above the outer lip of the parietal wall ( Fig. 9EView Fig). Two horizontal palatalis: both Hpt1 and Hpt2 are thin, situated just above the columella, posterior longer than anterior ( Fig. 9EView Fig). Columellaris distinct ( Fig. 4BView Fig 3View Fig). Columellar tooth prominent. Protoconch smooth, Wh approx. 2.0, with small pits evenly distributed, no radial ribs ( Fig. 4BView Fig 1View Fig). Teleoconch with radial ribs; about 5–6 ribs/ 0.5 mm on the penultimate whorl; 5–7 ribs/ 0.5 mm on the body whorl towards the aperture ( Figs 4BView Fig 2View Fig, B 4View Fig). No spiral striation. Umbilicus closed. Peristome with two lips; outer lip slightly reflected; inner lip thick and forming a thin callus on the penultimate whorl. Angular edge of the peristome rounded. Basal edge of the peristome outwardly directed.


The species name refers to the type locality ‘Godawari’.

Diplommatina godawariensis  sp. nov. is similar to D. diplocheilus Benson, 1857  from Khasi Hills, NE India “Teria Ghat, Khasi Hills” ( Hanley & Theobald 1876: pl. 140, figs 2–3), but D. godawariensis  sp. nov. has a smaller columellar tooth and a narrower penultimate whorl. The aperture of D. godawariensis  sp. nov. is rather similar to that of D. pachycheilus  , but this latter species has more tumid apical whorls and its penultimate whorl is slightly narrower than that of D. godawariensis  sp. nov.
