( Figs 1B , 3 )

Diagnosis. This species differs from other species of this genus in having the following characters: syntergosternite 7+8 with 3 pairs of thick, long setae medially ( Fig. 3A ); epandrium deeply constricted more than one-half width mid-dorsally, strongly protruded mid-posteriorly ( Fig. 3A ); cercus broadened dorsoally in posterior view ( Fig. 3B ); surstylus slender, with 1 strong seta apically ( Fig. 3A ).

Description. Characters common to L. hirsutina sp. nov. are not referred to in the following description. Male: Abdominal tergites yellow with black patches on fourth to sixth ( Fig. 1B ); all sternites yellow except black fifth. Female: Abdominal tergites yellow with black patches on fourth and fifth as in male, sixth tergite black with yellow, longitudinal stripe medially; all sternites yellow except black sixth. Male terminalia: Epandrium with 13 setae per side and pubescence dorsally ( Fig. 3A ). Hypandrium with 2 pairs of paramedian setae ( Fig. 3C, D ). Aedeagus strongly sclerotized ( Fig. 3C, D ).

Type specimens. Holotype ♂ ( SCAU, No. 123293), CHINA: Menglun, Mengla , Yunnan alt. 680 m, 11.iv.2010, tree trunk, RY Su . Paratypes: 2♀ ( SCAU, No. 123294, 95), same data as holotype .

Etymology. A combination of the Latin words: seta + cauda, referring to the abdominal 6th tergite with 3 pairs of thick, long setae medially.
