簡介:"Extensus collectivus 體色為淡黃色,有一黑色帶從頭頂端部通過前胸及中胸,連接縫直到肘脈末端,在頭頂端部三分之一處收縮,然後至前端變寬。前翅在端部深褐色,沿著前緣室橫脈具黑色斑點和條紋,黑色斑點接近第二端室基部邊緣處,黑色條紋則沿著前緣室橫脈分佈,另一條較短條紋則位於第四端室內。頭長,側緣在眼前方平行一段距離後向端部集中。中央冠狀縫貫通頭頂。本種與 E. latus 類似,但不同處在於黑色帶的型式,和陰莖端部結構。截至目前為止,本種之寄主植物及相關生物學資料仍未知。本種敘述引用黃坤煒 (1989) 之文獻。General color of Extensus collectivus pale yellow, black band from apex of vertex through pro- and mesonotum, commissural suture to end of clavus, contracts at apical third of vertex and then expand to anterior. Tegmen deep brown at apex, and with black spot and strips, black spot near basal margin of 2nd apical cell, black strips along cross veins of costal cell, and a shorter stripe within 4th apical cell. Head elongate, the lateral sides parallel for a distance in front of eyes and then converging to apex; the median coronal suture through vertex. This species resembles E. latus but differs from latter by the patter of black band, and the apical structure of aedeagus. So far, the biological information and host plant of this species is still unknown. The description of this species based on the description of Huang (1989)."
