Review of the genus Mohrigia Menzel (Diptera, Sciaridae) from China Xu, Jun Shi, Kai Huang, Junhao Wu, Hong Zootaxa 2017 4300 1 71 98 8CW56 Xu & Huang Xu & Shi & Huang & Wu 2017 [151,590,613,639] Insecta Sciaridae Mohrigia Animalia Diptera 19 90 Arthropoda species scrobiculata sp. nov.     Materialexamined.  Holotype, male. China, Yunnan. Yingjiang, Tongbiguan, Mulianhuatang, 24°36.004'N, 97°39.139'E,  1341 m,  20-V-2009, leg. Su-Jiong Zhang[SM00711].  Paratype: 1 male, the same data as holotype[SM00678].   Diagnosis.This species is unique in its significantly concaved inner side of the slender gonostylus and the long and strong apical tooth arising from a lobe on the dorsal margin. The species is also characterized by two long flagellate setae on the inner side of gonostylus; tegmen trapezoid, parameral apodeme continuously sclerotized forming a central strip on dorsal side.   Description (male).Color. Head and thorax dark brown; antennae, palps, abdomen and hypopygium yellowish-brown; mesonotum brown; legs pale brown; wings fumose.  Head( Figs 11A, B). Eye bridge with 3 rows of facets. Maxillary palps 3-segmented, basal segment with 1 seta; 2nd segment with 5 setae; 3rd segment with 4–5 setae. Length/width index of 4th flagellomere: 2.22–2.57.  Thorax.Anterior pronotum with 3 setae, episternum 1 with 3 setae. Wings( Fig. 14E). Wing length 1.40–1.44 mm, width/length: 0.38. c/w: 0.63–0.68. R1/R: 0.42–0.50. r-m, stM, M1 and M2 bare, CuA1 and CuA2 bare. Legs( Fig. 11C). Length of spur/width of foretibia 0.82–1.03. Length of femur/length of metatarsus: foreleg 1.84. Length of metatarsus/length of tibia: foreleg 0.49–0.51, hind leg 0.42–0.45. Length of hind tibia/length of thorax 0.79– 0.97. Claws toothed.  Hypopygium( Figs 10A–D). The gonocoxite as long as the gonostylus. The gonostylus slender and inner side significantly concaved, densely setose on the apicoventral part, with a long and strong apical tooth arising from a lobe on the dorsal margin of gonostylus, two flagellate setae on the inner side of gonostylus present. Hypopygium without an intercoxal lobe. Tegmen trapezoid, parameral apodeme continuously sclerotized forming a central strip on dorsal side. Aedeagus relatively short. Sternite 10 with 1 seta on each half.   Distribution. China( Yunnan, Fig. 16).   Remarks.The paratypeshares most of the diagnostic characteristics with the holotype, except it has an intercoxal lobe on the ventral base of hypopygium, while the holotypelacks the structure. The intercoxal lobe is usually a very important character in  Mohrigia. However, this species is unique in having its significantly concaved inner side of the gonostylus and the long and strong apical tooth arising from a lobe on the dorsal margin, shared by both the typeand paratypespecimens, that were collected from the same site. Therefore, we treat the two specimens as the same species in this study. If more similar materials examined in the future, the character will have to be evaluated again.   Etymology.This species is named after its significantly concaved inner side of gonostylus, from the Latin adjective scrobiculatus, meaning concave. 1585189624 2009-05-20 Su-Jiong Zhang China Material 1341 24.600067 Mulianhuatang 1 97.65231 Tongbiguan 19 90 1 1 Yunnan holotype
