Anthidium (Anthidium) tasitiense Niu & Zhu , sp. nov.

( Fig. 32 a–h, Fig. 33 a–h, male)

Diagnosis: T7 ( Fig. 33c ), clypeus ( Fig. 32b ) and maculations on terga ( Fig. 33b ) of the new species is similar to those of A. (A.) punctatum Latreille, 1809 , but the new species can be distinguished from A. (A.) punctatum Latreille, 1809 by the spiculum of S8 not elongate, slightly narrower than disc ( Fig. 33f ) and anterior surface of antennal scape yellow ( Fig. 32b ).

Description: Male. BL = 8.5–10.3 mm ( Fig. 32a ); head broader than long, HW: HL = 63: 55 ( Fig. 32b ); gena slightly narrower than eye, GW: EW = 15: 17. Clypeus broader than long, with wide impunctate longitudinal midline ( Fig. 32d ); mandible with three teeth, apical one sharp and longest, second one and third one about half long as the apical one; omaular carina absent; pronotal lobe rounded anteriorly; scutellum rounded posterolaterally, without tooth, not greatly overhanging metanotum and propodeum ( Fig. 32c ); propodeum without fovea behind spiracle ( Fig. 32e ); fore wing with two submarginal cells, the cells nearly equal in length, second recurrent vein meets distal to second submarginal crossvein; cu-v vein of hind wing oblique, longer than half than second abscissa of M+Cu ( Fig. 32h ); arolia absent ( Fig. 32f ); S7 inner distal margin elongate, forming a projection rounded apically ( Fig. 33e ); spiculum of S8 not elongate, slightly narrower than disc, both lateral margin with a projection respectively, emarginate medially, apical process of S8 single, broadly rounded apically ( Fig. 33f ); T6 with distinct long and sharp lateral spine ( Fig. 33c ); T7 with broad rounded lateral spine, without submedian spine ( Fig. 33c , Fig. 33d ), the median spine of T7 acute triangular or subrectangular ( Fig. 33c , Fig. 33d ); genitalia respectively shown in Fig. 33g (in dorsal view) and Fig. 33h (in lateral view). Metasomal terga with obvious yellow maculations, T1 with two light yellow lateral spots, T2–T7 with light yellow bands, bands not interrupted medially, and the bands on T3–T7 with shallow V-shaped forward notches ( Fig. 33b ). Integument black, except light yellow on anterior surface of antennal scape ( Fig. 32b , Fig. 32 c-1), dark blackish brown on anterior surface of F3–F11 ( Fig. 32b ), clypeus ( Fig. 32b ), lower part of paraocular area ( Fig. 32d ), outer surface of mandible except teeth ( Fig. 32d ), one small marking on vertex near apex of eye respectively ( Fig. 32c ) or band on vertex ( Fig. 32 c-1), lateral margin of scutum ( Fig. 33a ) or anterior lateral margin and lateral margin of scutum ( Fig. 33 a-1), axilla ( Fig. 33a ), posterior lateral margin of scutellum ( Fig. 33a ), tegula except central part ( Fig. 33a ), metasomal terga maculations ( Fig. 33b ), outer surface of tibiae, outer surface of basitarsi and distitarsi; yellowish-brown on central part of tegula ( Fig. 33a ) and outer surface of mediotarsi. Fore wing hyaline, veins and stigma dark brownish ( Fig. 32g ). Lower part of clypeus, both lateral sides of antennal scape, frons, lower part of gena, and mesepisternum covered with long and dense white pubescence ( Fig. 32a , Fig. 32b ); vertex, scutum and scutellum covered with paler yellowish-white pubescence ( Fig. 32b ).

Female, unknown.
