Godwin-Austen 1897: 11, 12, pl. 65, figs 7, 7 a, 7 b. Gude 1921: 340. McGhie 2008: 11. Diplommatina (Metadiancta) compacta — Kobelt and Möllendorff 1898: 138. Kobelt 1902: 449. Type material examined. India • Syntypes. NHMUK 1903.7.1.2179 (28 shells; Fig. 16 A) from South of Barak, Munipur (figured in Godwin-Austen 1897: pl. 65, figs 7, 7 a); Godwin-Austen coll. Diagnosis. Shell dextral, ovate-fusiform, translucent, whitish. Whorls ~ 7, well rounded; spire elevated-conical; suture wide, shallow. Teleoconch: earlier whorls with weak, narrowly and equally spaced radial ribs; penultimate and last whorls with very weak radial ribs to nearly smooth surface. Penultimate whorl convex, wider than last whorl. Aperture circular; columellaris very strong, directed downward. Peristome expanded, double, multi-layered; outer peristome slightly broader than inner peristome; parietal callus thickened, expanded. Columella curved; umbilicus closed. Distribution. This species is known only from its type locality in Barak, Manipur State, India. The record from Myanmar, however, lacks a precise locality (Gude 1921), and the presence there has not yet been reconfirmed. Remarks. There are four additional syntype shells housed in The Manchester Museum, University of Manchester (EE. 3511 / 99) (McGhie 2008).
