description: Hungarella tulongensis Crasquin n. sp. (Fig. 8 A-F)
TYPE MATERIAL. — Holotype (P6M2662): one complete carapace (Fig. 8A); paratype (P6M2666): one complete carapace (Fig. 8D).
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 ” 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 genus needs re-collection and re-description).
Order PALAEOCOPIDA Henningsmoen, 1953 Superfamily indet. Family indet.
