Mohrigia ovoidea Xu & Huang  , sp. nov.

( Figs 9View FIGURE 9, 15View FIGURE 15 A, 16)

Material examined. Holotype, male. China, Fujian. Wuyishan, Xingcun, Xianfengling , 27°43'30"N, 117°39'36"E, 2-V-2014, leg. Mei Qin [SM02450].GoogleMaps 

Diagnosis. The species is characterized by its ovate gonostylus with a strong apical tooth arising from a dorsal lobe, with two flagellate setae on the ventral mesial margin of gonostylus; hypopygium without an intercoxal lobe, only bearing three slightly long setae on the intercoxal area; tegmen triangular, parameral apodeme continuously sclerotized forming a central strip on dorsal side.

Description (male). Color. Head, antennae and thorax dark brown; palps, abdomen and hypopygium yellowish-brown; mesonotum brown; legs pale brown; wings fumose.

Head ( Figs 9View FIGURE 9 D, E). Eye bridge with 3 rows of facets. Prefrons with 6 setae. Maxillary palps 3-segmented, basal segment with 1 seta; 2nd segment with 6 setae; 3rd segment with 5 setae. Length/width index of 4th flagellomere: 3.74.

Thorax. Anterior pronotum with 2 setae, episternum 1 with 3 setae. Wings ( Fig. 15View FIGURE 15 A). Wing length 1.92 mm, width/length: 0.38. c/w: 0.71. R1/R: 0.48. r-m, stM, M1 and M2 bare, CuA1 and CuA2 bare. Legs ( Fig. 9View FIGURE 9 F). Length of spur/width of foretibia 1.00. Length of femur/length of metatarsus: foreleg 1.57. Length of metatarsus/length of tibia: foreleg 0.52, hind leg 0.35. Length of hind tibia/length of thorax 1.01. Claws toothed.

Hypopygium ( Figs 9View FIGURE 9 A –C). The gonocoxite as long as the gonostylus. The gonostylus ovate, densely setose on the apicoventral part, with a strong apical tooth arising from a dorsal lobe, two flagellate setae on the ventral mesial margin of gonostylus present. Intercoxal lobe of hypopygium absent, only bearing three slightly long setae on the intercoxal area. Tegmen triangular, parameral apodeme continuously sclerotized forming a central strip on dorsal side. Aedeagus relatively short. Sternite 10 with 1 seta on each half.

Distribution. China (Fujian, Fig. 16View FIGURE 16).

Remarks. The new species resembles M. angusta  ( Figs 1View FIGURE 1 A, B) in having an ovate gonostylus with the subapical the tooth arising from a dorsal lobe, and the intercoxal lobe absent. The difference is mainly in the form of their ovate gonostylus, which is twice as long as wide in the new species, while M. angusta  has a slender gonostylus that is about three times as long as wide.

Etymology. This species is named after its ovate gonostylus, from the Latin adjective ovoideus, meaning ovate.
