Araliacothrips gen.n.

Macropterous, body slender, dark brown, with strongly reticulate surface. Antennae 8-segmented, III and IV with long apical neck ( Figs. 5, 7 ), III and IV each with sense cone long and forked, IV with one simple sense cone laterally ( Fig. 5 ); segment VI constricted at base, VIII much longer than VII. Head completely reticulate, sculpture on dorsal surface not raised; slightly longer than wide, cheeks parallel, constricted behind eyes and at basal neck; compound eyes with 6 weakly pigmented facets; occipital region without apodeme or collar; ocellar setae pair I present, pair III on anterolateral margins of ocellar triangle; maxillary palps 2-segmented. Pronotum reticulate, with convex posterior margin, setae small and equal in length ( Fig. 9 ). Mesoscutum with short posteromedian cleft; metascutum reticulate without median strong triangle, median pair of setae far from anterior margin, campaniform sensilla present ( Fig. 13 ); metathoracic endofurca simple and not sinuate, with short Y-shaped arms ( Fig. 15 ). Femora and tibiae reticulate, tarsi 1-segmented. Fore wing with apex acute and posterior fringe cilia wavy, first vein with setal row widely interrupted, second vein with scattered setae ( Fig. 6 ). Abdominal tergites reticulate, tergal median setae small; posterior margin of tergite I with dentate craspedum ( Fig. 10 ); lateral thirds of tergites with reticles; tergite II not constricted and without strong microtrichia ( Fig. 11 ); tergites III–VIII with arched antecostal ridge, median tergal setae small and well separated from each other, sub-median setae slightly curved or sigmoid ( Figs 12, 14 ); both tergites and sternites with broad craspedum on segments II–VIII; tergite VIII with posteromarginal comb present laterally ( Fig. 14 ); tergite X symmetric, with median split complete; setae on tergite IX longer than tergite X ( Fig. 14 ); sternites with setae small. Male sternites IV–VII with transverse pore plate anterior to antecostal ridge ( Fig. 4 ); tergite IX with paired thorn-like setae ( Fig. 3 ).
