Genus Broscodera Lindroth, 1961

Broscodera Lindroth, 1961:150 . Type species: Miscodera insignis Mannerheim, 1852:296 .

Sinobrosculus Deuve, 1990:186 . Type species: Sinobrosculus dreuxi Deuve, 1990:187 .

Diagnosis. Members of this genus can be distinguished from those of other broscine genera in the region by the following combination of character states: body small to moderate in size (BL<13.0 mm); body surface without metallic reflection; head with post-temporal transverse sulcus moderately deep and broadly or narrowly punctate; genal ridge present, extended from posterior region of head to ventral margin of eye; maxillae with three setae on eustipes, stipes with dorsobasal setae distinctly less than half as long as ventrobasal setae; mentum with one or two pairs of setae present, paramedial region deeply foveate; submentum with three or four pairs of setae; antennae with antennomere 3 with sparse pubescence in apical one-third to one half, antennomere 4 pubescent; pronotum with lateral margination (lateral bead) present and complete from apical margin to pronotal base, one pair of basolateral setae present; elytra with parascutellar seta absent, discal setae absent, umbilicate setal series comprised of one post-humeral and three preapical setae; male pro- and mesotarsi each with small pads of adhesive setae on tarsomeres 1 and 2 only.

Taxonomic notes. Members of the nominate subgenus ( Broscodera insignis ) have only one pair of setae on the mentum, those of subgenus Sinobrosculus , including those of both species described below, have two pairs of setae ( Deuve 1990; Roig-Juñent 2000).

Diversity and geographical distribution. At present, this genus includes only four described species and two additional subspecies arrayed in two subgenera. Broscodera s. str. includes a single western North American species, and subgenus Sinobrosculus includes three described species and two additional subspecies. These previously described species of Sinobrosculus are recorded from Gansu and Sichuan Provinces, China and Nepal. The two new species described here represent the first species recorded from Yunnan Province.
