Linan sp. indet.

( Figs. 6 , 42 , 48 )

Material studied (3 ♀♀). 3 ♀♀, ‘ CHINA: JIANGXI Prov. / Sanqingshan Mt. / alt. 1,500 –1,600 m, 3.v.2005 / HU & TANG leg.’ ( SNUC).

Description. Female ( Fig. 6 ). BL 2.35–2.49, BW 1.07–1.08 mm, HL 0.59–0.60 mm, HW 0.52–0.54 mm, PL 0.52–0.54 mm, PW 0.55–0.57 mm, EL 0.60–0.64 mm, EW 0.99–1.01 mm, AL 0.64–0.71 mm, AW 1.07–1.08 mm. Eyes each composed of about 15 facets.

Distribution and habitat. This species is found only from Sanqingshan Mountain, Jiangxi Province (South-eastern China). Specimens were sifted from leaf litter of coniferous and broad leaf forest ( Fig. 48 .)

Remarks. Due to the lack of male specimens, this species cannot be placed in a species-group. But it is apparently a distinct species due to the small eyes each composed of about 15 facets in the female, while the eyes of female in L. chinensis and L. inornatus sp. nov. are composed of about 20 facets. The number of facets of the compound eyes is usually a reliable character for use in separating closely allied species in Pselaphine beetles. We would like not to fully describe and name this species until a male specimen is found.
