description: Mohrigia inflata Shi & Huang, sp. nov.
(Figs 4, 15 B, 16)
Lycoriella longirostris Yang, Zhang & Yang, 1995: 210 and 211 (misidentification, in part).
Material examined. Holotype, male. CHINA. Hubei, Mts. Shennongjia, Yinyuhe, sweep-net, 16-V-2012, leg. Kai Shi [SM01637]. Paratypes, Zhejiang. Kaihua, Mt. Gutianshan: 2 males, 17-VII-1992, leg. Xue-Xin Chen [SM10009, SM10011]; 1 male, yellow pan trap, 21-VII-1992, leg. Hong Wu [SM10010] (all males labeled as paratypes of Lycoriella longirostris, Yang, Zhang & Yang, 1995). 1 male, Anji, Mt. Longwangshan, sweep-net, 1- V-2012, leg. Kai Shi [SM01605].
Diagnosis. T he species is characterized by its ovate gonostylus with a strong apical tooth arising from a strong dorsal lobe, three flagellate setae on the ventral mesial margin of gonostylus; hypopygium with a small conical setose intercoxal lobe; tegmen slightly and smoothly curved, parameral apodeme continuously sclerotized forming a central strip on dorsal side and laterally sclerotized.
Description (male). Head dark brown; antenna, thorax, abdomen and hypopygium brown; palps pale brown; legs yellowish-brown; wings fumose.
Head (Figs 4 C, D). Eye bridge with 3 rows of facets. Prefrons with 15 setae. Clypeus with 1–3 setae. Maxillary palps 3-segmented, basal segment with 2 setae. Length/width index of 4th flagellomere: 2.60–3.54.
Thorax. Anterior pronotum with 3–6 setae, episternum 1 with 5–7 setae. Wings (Fig. 15 B). Wing length 2.12– 2.32 mm, width/length: 0.42–0.47. c/w: 0.61–0.72. R1/R: 0.70–0.80. M, stM and CuA nonsetose. r-m with 0–4 setae. Legs (Fig. 4 E). Length of spur/width of foretibia 0.87–1.10. Length of femur/length of metatarsus: foreleg 1.17–1.48. Length of metatarsus/length of tibia: foreleg 0.56–0.64, hind leg 0.48–0.54. Length of hind tibia/length of thorax 1.14–1.39. Claws toothed.
Hypopygium (Figs 4 A, B). The gonocoxite as long as the gonostylus. The gonostylus ovate, densely setose on the apicoventral part, with a strong apical tooth arising from a strong dorsal lobe, three flagellate setae on the ventral mesial margin of gonostylus present. Hypopygium with a small conical setose intercoxal lobe. Tegmen slightly and smoothly curved, parameral apodeme continuously sclerotized forming a central strip on dorsal side and laterally sclerotized. Aedeagus relatively short. Sternite 10 with 1 seta on each half.
Distribution. China (Zhejiang, Hubei, Fig. 16).
Remarks. Three paratypes of Lycoriella longirostris, are here treated as M. inflata sp. nov. The argument for the misidentification is discussed above in the remarks of M. megalocornuta (Mohrig & Menzel, 1992).
The new species is similar to M. globulosa (Figs 3 A–C) in both having a much inflated gonostylus, but the gonostylus is relatively ovate in this specis, and nearly spherical in M. globulosa. Difference is also seen in the shape of the tegmen, which is smoothly curved in M. inflata, while triangular in M. globulosa.
Etymology. This species is named after its inflated gonostylus, from the Latin adjective inflatus, meaning inflated.
