ETYMOLOGY. — From the Tulong section, type locality.
MATERIAL EXAMINED. — 230 complete carapaces and 18 isolated valves.
DIMENSIONS. — L = 380-570 µm; H = 240-350 µm. Holotype: L = 506 µm; H = 316 µm. Paratype: L = 514 µm; H = 308 µm.
TYPE HORIZON. — Unit V,Tulong Formation, Spathian, lower Triassic.
TYPE LOCALITY. — Tulong section, Southern Tibet .
OCCURRENCE. — Tulong section, SouthernTibet. Samples 06Ti20, 06Ti25, 06Ti26, 06Ti28-32 and 06Ti34, units V and VI, Spathian-Anisian, Early-Middle Triassic.
DIAGNOSIS. — A species of Hungarella with dorsal parts straight and carapace laterally compressed at AB.
DESCRIPTION
PD and AD parts long and straight on RV, straight to gently convex on LV; the two parts are at a 140-150° angle; AB regularly arched with a clear lateral flattening, maximum of convexity located around mid-H; VB regularly convex on both valves; PB with quite large radius of curvature, maximum of curvature located a little below mid-H; carapace subtriangular with maximum of H at mid-L or a little in front of; H/L = 0.62;

A, right lateral view of left valve (P6M2629); J -M, Triassicindivisia tibetinella Crasquin n. gen., n. sp.; J, holotype (P6M2631), left lateral view of a complete carapace; K, paratype (P6M2632), left lateral view of a complete carapace; L, left lateral view of a complete carapace (P6M2636); M, left lateral view of a complete carapace (P6M2637). Scale bars: 100 μm.
LV overlap of LV on RV very weak all around the margins; surface smooth.
REMARKS
Hungarella tulongensis Crasquin n. sp. differs from the Upper Anisian species “ Hungarella View in CoL ” reniformis Méhes, 1911 from Lake Balaton ( Hungary; Méhes 1911; Monostori 1995) by H/L smaller and a maximum of convexity of BP located lower. Hungarella elongata (Blake, 1876) from the Late Triassic (Rhaetian) of Great Britain ( Anderson 1964) has the same anterior structure but the dorsal outline is less angular and H/L is smaller. Hungarella ovata Zheng, 1976 from the Rhaetian of South China ( Zheng 1976) is also relatively close to the new species but has a concave VB on RV and a PB with smaller radius of curvature ( Hungarella View in CoL genus needs re-collection and re-description).
