Baschkirina cf. ballei Crasquin, 2010

( Fig. 24 I-L)

Baschkirina ballei Crasquin in Crasquin, Forel, Feng, Yuan, Baudin & Collin, 2010a: 358, fig. 23R-W.

MATERIAL EXAMINED. — 35 complete carapaces.

DIMENSIONS. — H = 0.23-0.42 mm, L = 0.32-0.64 mm, H/L = 0.65-0.75.

OCCURRENCES. — Samples 08LO02-1, 08LO02-2 and 08LO02-10, Tham Nam Maholan section, Nam Maholan Formation, Loei Province, northeastern Thailand, Early Permian; sample 07LB04-8, Phu

Lam Yai section, Tak Fa Formation, Nakhon Sawan Province, central Thailand, Early Permian ; sample 07 PB03-3 , Khao Kana section, Pha Nok Khao Formation, Phetchabun Province, central Thailand, Early Permian ; sample 07 PB04-5 , Nong Phai section, Pha Nok Khao Formation, Phetchabun Province, central Thailand, Early Permian .

REMARKS

The studied specimens look similar to Baschkirina ballei Crasquin, 2010 from latest Permian of Meishan section, South China ( Crasquin et al. 2010a: 358, figs 23R-W). Baschkirina ballei have longer PDB and less compressed AB.

Baschkirina cf. huzhouensis Forel, 2010 ( Fig. 21 N-P)

Baschkirina huzhouensis Forel in Crasquin, Forel, Feng, Yuan, Baudin & Collin, 2010a: 359, fig. 23E-H.

MATERIAL EXAMINED. — Five complete carapaces.

OCCURRENCES. — Sample 08LB01-1, Khao Som Phot section, Tak Fa Formation, Lopburi Province, central Thailand, Middle Permian.

DIMENSIONS. — H = 0.23-0.26 mm,L = 0.45-0.49 mm,H/L= 0.50-0.52.

REMARKS

Our specimens are similar to B. huzhouensis Forel, 2010 from the latest Permian of Meishan section, South China ( Crasquin et al. 2010a: 359, fig. 23E-H) in having long carapace with straight DB and PDB. However, AB of B. cf. huzhouensis is less compressed and located above mid H, but AB is located at mid H in our specimens.
