Wumea clypealis Carvalho 1987: 187 .

DIAGNOSIS: Differentiated from similar taxa by characters listed in generic diagnosis and genital capsule with broadly rounded ventral projection ( fig. 7a ); broadly crescentshaped right paramere ( fig. 7b ); aedeagus with elongate basal sclerite and two broad lobal sclerites ( fig. 7d ).

REDESCRIPTION: Coloration ( fig. 1f ): Head yellowish brown with vague red maculations on clypeus and mandibular plates. Antennae yellowish brown becoming darker distally. Prothorax yellowish brown; posterior portion of disc darker; collar undifferentiated; dorsal margin of propleuron undifferentiated, undifferentiated ventrally. Scutellum pale tan, in contrast to darker pronotum and surrounding clavus. Pleura of meso- and metathorax dark brown. Hemelytra predominately reddishbrown, anterior third more deeply suffused with red; margin of clavus undifferentiated; cuneus margined with red, anterior and posterior portions with larger red maculations. Abdomen dark brown throughout. Legs predominately yellowish brown becoming brown distally, ventrally undifferentiated. Structure: As in generic description. Genitalia ( fig. 7 ): Genital capsule subconical with large aperture; ventral projection weakly asymmetrical, slightly skewed to right, broadly round- ed. Left paramere branched basally; basal lobe with papillate apex; main body of paramere hooked apically with weak teeth in hook; right paramere broadly crescent-shaped with papillate apex. Theca sclerotized basally, simple. Aedeagus with elongate basal sclerite and two broad lobal sclerites, both lobal sclerites with single medial tooth; secondary gonopore as in generic description.

FEMALE ( fig. 1b ): Similar to males. Genitalia: Ovipositor as in generic description. Vestibulum simple, saclike; sclerotized rings large, weakly sclerotized, laterally folded for entire length, over twice as long as broad, aperture irregular; dorsal labiate plate simple; posterior wall with paired interramal sclerites; interramal lobes (K-structures of Slater 1950) one-fifth the length of the ovipoister, semicircular, slightly divergent, distinctly spinulose.

REMARKS: The male genitalia of Wumea cassisi differs substantially from that of the type species of the genus. Wumea cassisi possesses a large barrel-shaped genital capsule, a branched right paramere, and an aedeagus with spiculi. In contrast, W. clypealis has a simple right paramere, a weakly flattened conical genital capsule, and an aedeagus with lobal sclerites and basal process. Despite these differences, the two taxa are remarkably similar on a superficial level and are provisionally placed in the same genus.
