Macropsis (Spinomacropsis) subgen. nov.

Type-species: Macropsis flavovirens Kuoh, 1992

Description. Body form (Figs. 1 – 4) typical for genus Macropsis .

Width of head at eye level (including eyes) equal to that of pronotum, crown distinctly shorter medially than laterally (Figs. 1, 3). Surface of head and face uneven, with distinct striations and punctations (Figs. 1, 3 and 4). Face with lower part strongly inflated, upper part of frons with distinct carina medially, lora concealed by prominent lobe of frons, without distinct suture between them, distance between ocelli six times as great as that from ocellus to adjacent eye (Fig. 4). Pronotum with dense and oblique striations, merely 2.3 times as wide as its middle length, with distinct longitudinal carina in middle (Figs. 1, 3). Scutellum nearly triangular, about 1.3 times as long as pronotum (Figs. 1, 3). Forewings hyaline, with 3 anteapical and 4 apical cells (Fig. 2). Hind femoral macrosetae 2+1; AD row of hind tibia with 10 macrosetae, AV row with 5, PD row with 8, PV row dense and slender.

Male genitalia. Pygofer lobe broad basally, without membranous area in caudal region, main pygofer process arising from ventral margin long, attaining dorsal margin, caudal margin with additional process bent dorsally and more or less parallel to main one, and with small stout seta on dorsolateral margin at base of process (Fig. 11). Subgenital plate, aedeagus, connective, style and dorsal connective of male genitalia similar in shape to those of nominotypical subgenus.

Distribution. China (Yunnan Prov.).

Remarks. The new subgenus resembles other subgenera of Macropsis in having the dorsal connective unsclerotized and unarmed, the pygofer spines long and straight and arising from the caudoventral margin and the dense and strongly oblique pronotal striations, but can be easily distinguished from other subgenera by the shape of the male pygofer, which bears an additional process and stout seta on the posterior margin and lacks membranous regions caudally. It also differs from Pediopsoides in having double or multifid pygofer spines and an unsclerotized dorsal connective.

Etymology. The subgenus name is derived from the Latin “ spino- ” due to the pygofer lobe with additional spines on the caudal margins. The gender of the subgenus is feminine.
