In this paper two new species of the mycetophilids genus Leia are reported. The type specimens are deposited in the Insect Collections of China Agricultural University.1 Leia guangxiana sp.nov. (Figs.13) Male. Wing length 4.85.0 mm. Head brownish. Palpus yellow. Antenna brownish to brown, with scape, pedicel and 1st flagellar segment yellow. Ocellae not touching eye margin. Pronotum yellow. Mesonotum yellow, with three dark wide brown longitudinal stripes. Scutellum yellow, with one “T” brown marking and 4 long setae. Legs brownish yellow, but midale of ventral side of femora with brown markings, apical part of hind femur, middle and hind tibiae brown. Wing hyaline, with 4 brown markings.Halter yellow. Abdominal tergites brown, tergites ⅡⅦ with anterior margins yellow. Sternites brownish. Male hypopygium as in Figs.12. Female. Wing length 4.86.2 mm. Color as in male. Female terminalia as in Fig.3. Holotype ♂, paratypes 6♂♂,17♀♀,Maoershan, 2100m ,Guangxi, Aug.19,1992, by YANG ChiKun and YANG ChunQing, light trap. This new species is similar to L.winthemi Lehmann, but can be seperated from the latter by its dististyle curved apically and basistyle with 1 pair of subprocesses.2 Leia ravida sp.nov. (Figs.46) Male. Wing length 4.9 mm. Head brown. Palpus yellow. Antenna yellow to brownish. Ocellae not touching eye margin. Pronotum yellow, with 2 brown markings. Mesonotum yellow, with 3 wide brown longitudinal stripes, lateral stripes black brown. Scutellum with 4 long setae. Legs yellow, but apical part of middle and hind coxae with brown markings, basilar and apical parts of hind femur dark brown. Wing hyaline, with brown subapical band. Halter yellow. Anterior margins of abdominal tergites ⅡⅤ and posterior margins of tergites ⅡⅥ with narrowly yellow. Sternites ⅠⅢ yellow, sides of sternite Ⅲ with brown markings. Sternites Ⅳ Ⅴ dark brown, with posterior margins yellow. Male hypopygium as in Figs.45. Female. Wing length 5.4 5.6mm . Color as in male. Female terminalia as in Fig.6. Holotype ♂, paratypes 4 ♀♀, Antangping, 1500m , Maoershan, Guangxi, Aug.18, 1992, by YANG ChiKun and YANG ChunQing. This new species is similar to L.arcuata Brunetti and L. pauliani Matile, but differs in color, dististyle curved, without lateral branch and basistyle without obvious subprocesses.
