Longicornus brevispinus View in CoL sp. nov. Figs 1-4 View Figures 1–4 , 5-11 View Figures 5–11
Description.
Body robust, yellowish brown ( Figs 1-4 View Figures 1–4 ). Vertex with paired irregular dark brown short coalescing bands. Eyes black, ocelli pale yellow. Face marked with dark brown. Pronotum with irregular fuscous patches. Forewing brownish, with scattered hyaline areas, veins dark brown. Legs dark brown.
Head including eyes slightly narrower than pronotum. Vertex with fore margin produced roundly, median length distinctly shorter than width between eyes. Ocelli located on anterior margin of vertex. Frontoclypeus distinctly longer than wide, anteclypeus expanded apically. Antennae arising near lower corner of eye. Pronotum with anterior margin roundly produced and posterior margin concave, longer than vertex. Mesonotum triangular, slightly shorter than pronotum, with transverse suture depressed. Forewing with four apical and three subapical cells, about 3 times as long as wide, appendix wide. Hind wing with three apical cells and two anteapical cells. Fore femur row IC with a row of short setae, row AM with 1 stout seta, 2 dorsoapical setae, and row AV with several short setae in basal half. Fore tibia with 4 macrosetae in row AD and numerous macrosetae decreasing in length toward the base in row AV. Hind femur broadened distally and slightly bowed, apical setal formula 2 + 2 + 1. Hind tibia flattened and nearly straight, row PD with 12 macrosetae decreasing in length toward the base; row AD with 10 long stout setae and 1-4 shorter stout setae between each long seta; metabasitarsomere with 4 platellae and 2 setae on apical transverse row.
Male genitalia: Pygofer longer than broad in lateral view, with many long macrosetae in posterior half ( Fig. 5 View Figures 5–11 ). Valve subtriangular ( Fig. 6 View Figures 5–11 ). Subgenital plate with wide base, narrowed posteriorly, with 6 setae along lateral margin, and mesal margin deeply concave near apex ( Fig. 7 View Figures 5–11 ). Style relatively narrow, apical process acute, turned laterally ( Fig. 11 View Figures 5–11 ). Connective articulated with aedeagus, Y-shaped with stem long ( Fig. 10 View Figures 5–11 ). Aedeagus very short and stout with base broad in lateral view, gradually tapered to apex in lateral view, with a pair of short and robust apical processes with truncate apex, gonopore apical ( Figs 8 View Figures 5–11 , 9 View Figures 5–11 ).
Measurement.
Length (including tegmen): ♂, 5.6 mm.
Type material.
Holotype ♂, China: Yunnan Prov., Pingbian country, Daweishan, 22 May 2015, coll. Jiajia Wang (GUGC).
Distribution.
China (Yunnan).
Remarks.
The new species can be distinguished by the very short and stout aedeagus with a pair of short and robust apical processes with a truncate apex.
Etymology.
The species name is derived from the Latin word " brevis " and " spinus ", referring to the short apical processes of the aedeagal shaft.
