FIGURES. 123–129. Macropsis tuberculiformis sp. nov. 123—male pygofer and subgenital plate, lateral view; 124—male abdominal apodemes of 2nd sternite; 125—aedeagus, lateral view; 126—same, ventral view; 127—style, dorsal view; 128—connective, dorsal view; 129—same, lateral view.

Appearance typical for genus Macropsis . Body stout. Head curved forward, blunt on vertex, narrower than pronotum, weakly curved in profile. Frons with a longitudinal carina. Pronotum broad, declivous, striae and longitudinal carina distinct. Scutellum triangular, distinctly punctated in anterior part, with one heavy notch on each side of midline in posterior part. Tegmina semi-hyaline.

Abdominal apodemes of 2nd sternite slender, bent inwards, with narrow truncate tips (Fig. 124).

Pygofer broad, pygofer processes slender, short, not reaching dorsocaudal margin, with three setae in middle (Fig. 123). Subgenital plates slender, of almost the same width throughout all their length (Fig. 123). Aedeagal shaft very wide in lateral aspect, tapering towards end in distal half; slender, slightly widened at tip in ventral aspect, gonopore oval, subapical. Apex of aedeagus with numerous microscopic tuberculiform protrusions on dorsal margin (Figs. 125–126). Styles slender, with upturned tips (Fig. 127). Connective stout, with a finger-like protrusion in middle, both side arms bent to dorsum (Figs. 128–129).

Female unknown.

Body length (including tegmina): 3, 4.2 mm.

Host. Unknown.

Distribution. China (Sichuan prov.).

Diagnosis. The new species is similar to M. reni Li , but can be distinguished from the latter one by minute tuberculiform protrusions at apex of aedeagal shaft on dorsal margin; also, the new species differs from M. reni by yellow scutellum.

Etymology. The new species name is derived from the Latin word “ tuberculiformis ”, indicating that the tip of aedeagal shaft possess minute tuberculiform protrusions on dorsal margin.
