Liuzhinia larmae Forel n. sp. ( Fig. 6 View FIG C-G)
TYPE MATERIAL. — Holotype: one complete carapace (P6M2638; Fig. 6C View FIG ); paratype: one complete carapace (P6M2639; Fig. 6D View FIG ).
F, Bairdia anisica Kozur, 1970 , right lateral view of a complete carapace (P6M2613); G, Bairdia ? sp. D, left lateral view of a complete carapace (P6M2614); H, Bairdia cf. finalyi ( Méhes, 1911) , right lateral view of a broken carapace (P6M2620); I -M, Petasobairdia collini Forel n. sp.; I, right lateral view of a complete carapace (P6M2617); J, paratype (P6M2619), right lateral view of a nearly complete carapace (dorsal part of left valve is missing); K, right lateral view of a nearly complete carapace (P6M2613); L, right lateral view of a complete carapace (P6M2618); M, holotype (P6M2615), right lateral view of a complete carapace. Scale bars: 100 μm.
ETYMOLOGY. — Dedicated to Kriemhilde Larm, personal dedication.
MATERIAL EXAMINED. — 32 complete carapaces and 1 isolated valve.
DIMENSIONS. — L = 350-570 µm; H = 175-290 µm. Holotype: L = 406 µm; H = 200 µm. Paratype: L = 388 µm; H = 206 µm.
TYPE HORIZON. — Sample 06Ti08, Unit IIIb, Tulong Formation, Smithian, Lower Triassic.
TYPE LOCALITY. — Tulong section, Southern Tibet .
OCCURRENCE. — Tulong section, Southern Tibet . Samples 06Ti06, 06Ti08, 06Ti13, 06Ti14 and 06Ti32, units III to VI, Smithian-Anisian, Early-Middle Triassic.
DIAGNOSIS. — A Liuzhinia species with long and straight dorsal border; AB and PB with small radius of curvature.
DESCRIPTION
DB long and straight; AB with relatively small radius of curvature; VB long and gently convex on both valves; PB with small radius of curvature; AB and PB gently compressed laterally at the extremities of the carapace; maximum of H located in front of L anterior third; H/L = 0.51
REMARKS
Liuzhinia larmae Forel n. sp. is very close from Liuzhinia antalyaensis Crasquin-Soleau, 2004 from the early Induan of the Western Taurus ( Turkey, Crasquin-Soleau et al. 2004), Guangxi, South China (Crasquin-Soleau et al. 2006) and Southern Alps, Italy ( Crasquin et al. 2008). Here, the radius of curvature of AB is smaller, the DB is shorter, the H/L ratio is smaller and the thickness is less important in posterior part of the carapace.
NB: in Crasquin-Soleau et al. (2004: 286), there is a printing mistake in the diagnosis of Liuzhinia antalyaensis . It should be as follows:
DIAGNOSIS. — Species of Liuzhinia with long straight dorsal border and maximum of height located in the anterior third.
