Shell ovate, glossy; aperture triangular, adnate to the penultimate whorl. Differential diagnosis. The shell shape of Parasinoennea, new genus, is oval, whereas it is usually elongated and cylindrical in Sinoennea. The teleoconch of Parasinoennea is usually smooth, sometimes ornamented by low, blunt ribs, but is always glossy. In contrast, the ribs of Sinoennea are usually sharp and elevated, and the shell has a less glossy appearance. The main difference is in the aperture shape, which is triangular (in some species the palato-basal part distorted laterally) in Parasinoennea, new genus, but elongated oval and cylindrical in Sinoennea. The aperture is adnate (i.e., the parietal callus is attached to the penultimate whorl) in Parasinoennea, new genus, and the parietal callus is always clearly separated from the penultimate whorl in Sinoennea. The apertural dentition is not clearly different, although Parasinoennea, new genus, often possesses two tubercles (denticles) on the columellar peristome (anterior to the columellar lamella), which has not been observed in any Sinoennea species to our knowledge. The upper denticle is probably homologous with the upper denticle of Pupennea, new genus, and Platylennea, new genus. Included species. Parasinoennea demangei (Bavay & Dautzenberg, 1912) (northern Vietnam), P. formica (Bavay & Dautzenberg, 1912) (northern Vietnam), P. splendens splendens (Möllendorff, 1882) (Guangdong, China), P. splendens hongkongensis Möllendorff, 1885 (Hongkong, China), P. ovulum (Bavay & Dautzenberg, 1912) (northern Vietnam) (Figs. 9F–N, 22H). Etymology. The Greek prefix para- (παρά, meaning beside, next to, against, etc.) is attached to Sinoennea to show that it is separated from that ge [...]

Platycochlium — Richardson, 1988: 243. Platycochlium — Schileyko, 2000: 785. Type species. Platycochlium sarawakense Laidlaw, 1950, by original designation. Diagnosis. "Shell colourless, translucent when fresh, later white, low conical to almost discoidal in frontal view. Whorls with 4–5 varices next to the peristome (approximately one per &frac13;–½ whorl in the last whorls), each varix preceded by a number of ribs, the ribs crossed by a fine, concentric striation. Umbilicus wide, orbicular to elliptic. Aperture subtriangular with the parietal side concave. Peristome reflected, with a knob-like thickening on the palatal side, above which is a shallow sinus. Teeth four: one angularis, a sinuous lamella starting deep inside and ending in a thick knob; one short basalis; two deeply set palatales, the upper one hidden behind the palatal swelling of the peristome." (Vermeulen, 1991). Distribution. Endemic to Borneo.

Tonkinia — Schileyko, 2000: 785. Type species. Tonkinia mirabilis Mabille, 1887, by monotypy. Diagnosis.

Embryonic whorls smooth, subsequent whorls without regular sculpture. Aperture solute, irregularly quadrangular, nearly horizontal, with a little thickened, expanded margins and small parietal lamella. Palatal margin with thickening.

Shell surface shiny and finely axially ribbed at the teleoconch. Nepionic whorl faintly spirally ribbed. Umbilicus narrow, slit-like. Aperture rhomboid-oval with outward reflex, posteriorly and anteriorly more expanded. Peristome blunt, and reflexed along the aperture outline. Outer lip lateral profile straight and sinuous posteriorly. Sinuation present at columellar marginal profile. Aperture protruded against teleoconch outline from frontal view.Differentiating featuresThe species is closely related to P. angyaldorkae sp. nov., from which it differs by having a smaller number of whorls and a more prominent body whorl and, by a more narrow umbilicus and different shape of aperture. Conchologically, it represents an intermediate shell morphology between P. angyaldorkae sp. nov. and P. jakabi sp. nov., from which it can be distinguished by its more robust shell shape and different shape of the aperture with much broader posterior channel and by a smaller umbilicus. From sympatric P. ozimeci sp. nov. it differs by a larger shell with more whorls, a less conical shell shape and by a different shape of the aperture. Shell morphometry comparison [...]

Shell colour is translucent-whitish. Teleoconch surface covered by fine axial ribs and fine, close-set spiral cords forming a distinct cancellate structure. With dominating axial ribs. Nepionic whorl covered by 25 wavy granulose close-set spiral ribs connected by granulose irregular structures fusing at malleate apex. Open umbilicus, partly obscured by reflexed columellar margin.

DiagnosisT. klemmi has regularly narrow-conical shells (2.2 mm) with blunt apex, deep suture and widely spaced coarse ribs on shell surface, rounded callous irregular-oval shaped aperture and closed umbilicus. Lateral labral profile straight and columellar labrum only weakly sinuated. Protoconch surface overall covered by regular and deep pitting. DistributionT. klemmi is known from Vrelo "Stenjevac" and Vrelo "Baja" in Vrgorsko Polje (20 m a.s.l.) near Vrgorac and from Vrelo "Kutac" and other springs around Baćinska Lakes (0.8 m a.s.l.) near Ploče. The aquifer also receives its water from Rastok Polje (72 m a.s.l.). Remark sTravunijana klemmi represents the northernmost species of the genus. Its shell morphology has some features of the genus Belgrandia (e.g., Belgrandia torifera Schütt, 1961) known from the region, however its shell is more conical and lacks the typical callous varix near the labrum.

The new species are thoroughly compared with their congeners Trivellona opalina (Kuroda & Cate in Cate, 1979) and Trivellona schepmani (Schilder, 1941). Trivellona pulchra spec. nov. is especially distinguished by its unique ribbing and outline. Trivellona enricoschwabei spec. nov. differs by the ovate shell outline with a narrow aperture. Species of the genus Trivellona are deep water Triviidae mainly known from the central Indo-Pacific.
