Thagria irregularis Fan & Dai View in CoL sp. nov.
( Figs. 119–129 View FIGURES 119 – 129 )
Description. Body length of male 7.0–7.2 mm, female unknown.
Slender, medium sized species ( Fig. 119 View FIGURES 119 – 129 ). Crown light yellow-green, midline deep color, coronal suture brown; ocelli and eyes dark brown ( Fig. 121 View FIGURES 119 – 129 ). Face with clypeus and clypellus yellow, central area of clypeus and remainder of face light yellow ( Fig. 122 View FIGURES 119 – 129 ). Pronotum brown, covered with light brown nubs ( Fig. 121 View FIGURES 119 – 129 ). Mesonotum brown ( Fig. 121 View FIGURES 119 – 129 ). Forewing yellowish brown, with irregular dark patches, venation brown to black ( Figs. 119, 120 View FIGURES 119 – 129 ).
Head anteriorly arced, crown wider than eye width, extended about 1/3 median length anterad of eyes, coronal suture evident, about half of midline ( Fig. 121 View FIGURES 119 – 129 ). Face with clypeus long and broad, lateral margins slightly convex; clypellus basal half broad and swollen, distal half constricted ( Fig. 122 View FIGURES 119 – 129 ). Crown, pronotum and mesonotum midline ratio about 1:1:1.4 ( Fig. 121 View FIGURES 119 – 129 ). Forewing long, apex rounded, appendix narrowed ( Figs. 119, 120 View FIGURES 119 – 129 ).
Male genitalia. Pygofer in lateral view with paired stout processes on caudodorsal margin, end pointed ( Fig. 123 View FIGURES 119 – 129 ). Segment X ventral processes in dorsal view concealed, slender ( Fig. 124 View FIGURES 119 – 129 ). Subgenital plate with marginal long setae ( Fig. 125 View FIGURES 119 – 129 ). Dorsal connective Y-shaped, stem short, rami long, distally attached to base of segment X ventral processes by membrance ( Fig. 124 View FIGURES 119 – 129 ). Aedeagus symmetrical, reaching subapex of paraphysis, in lateral view curved dorsad ( Figs. 126, 127 View FIGURES 119 – 129 ); paraphysis asymmetrical, nearly triangular, apex attenuate, spinelike, lamellate process with irregular edge below, in lateral view slightly curved dorsad ( Figs. 126, 127 View FIGURES 119 – 129 ). Style long, reaching about midlength of paraphysis, narrowed to apex ( Figs. 128, 129 View FIGURES 119 – 129 ).
Type material. Holotype: ♂, CHINA: Guangxi, Yuanbaoshan, Alt. 580–1300 m, 14 July 2004, coll. Yang Maofa ( GUGC). Paratype: ♂, same as the holotype ( GUGC).
Etymology. The specific name is derived from Latin “ irregularis ”, referring to the irregular edge of the lamellate process on the paraphysis.
Remarks. This species is similar to T. apiculata Xu & Kuoh, 1998 in color shape, but it mainly differs in having the paraphysis with a spine-like process and a lamellate process distally ( Fig. 126 View FIGURES 119 – 129 ) compared to one spine in T. apiculata ( Xu & Kuoh 1998: 312, Fig. 2 View FIGURES 2 – 5 e, f).
