Type locality. China: Fujian.

Material examined. Topotype of Leprodera strix Gressitt , 1 female, China: Zhejiang province, West Tianmushan , 1 August 2011, leg. Guanglin Xie. The image of holotype of Leprodera strix Gressitt was shown by Lin (2015). Distribution . China: Fujian, Zhejiang, Sichuan .

Female. Length 22 mm, humeral width 9 mm. Body black, densely clothed with appressed grayish-brown pubescence, mixed with sparse grayish-white pubescence, grayish-white pubescence more obvious and uniform on ventral surface and legs. Antennae densely fringed with grayish-yellow hairs on basal seven segments, antennomere 3 to 11 clothed with grayish-yellow pubescence. Elytral surface sparsely mixed with short, erect black and grayish-white setae, more obvious on apical half; basal half of each side scattered with irregularly-sized small spots of grayish-white pubescence; a large rounded spot of black pubescence narrowly edged with white situated a short distance behind middle of each elytron.

Head with frons, gena and vertex coarsely rugose-punctate; vertex broadly concave, with small punctations on center. Frons wider than long, slightly convex above. Antenna longer than body, scape stout, about as long as fourth antennomere, third antennomere longer than scape and fourth. Pronotum wider than long, with an acute spine at middle of each side; disc slightly rough, with three low tubercles: two lateral tubercles small, one postmedial tubercle slightly larger and broadly grooved posteriorly. Scutellum semiround. Elytra with sides subparallel, apices rounded; base of each elytron with a feeble median longitudinal swelling, basal half with sparse coarse granules of different size and denser fine granules of more uniform size; surface with quite fine and shallow punctures. Legs moderately long, each mesotibia with an oblique groove near external apex, claws widely divergent.

Female genitalia. The spermatheca and sternites 7–8 are shown in figures 25–27. The blind end of spermathecal capsule narrowed-rounded, distinctly away from the C-form structure.
