Pseudodira clypealis Gordon, 1975

( Figs 8–22 , 35 )

Pseudodira clypealis Gordon, 1975: 207 (description); GORDON &ALMEIDA (1986): 373 (male genitalia); JADWISZCZAK & WĘGRZYNOWICZ (2003): 207 (catalogue).

Type locality. Brazil, Rio de Janeiro, Rio de Janeiro city.

Type material examined. HOLOTYPE: ♀, ‘ Brazil / Guanabara / Rio de Janeiro / XI 1963 // M. Alvarenga coll. // HOLOTYPE / Pseudodira clypealis Gordon’ ( USNM) . PARATYPE: ♀, ‘ Rio de Janeiro, Brazil / Acc. No. 2966 // PARATYPE / Pseudodira clypealis Gordon’ ( USNM).

Redescription. Length 5.8 mm; TL/EW = 1.16; PL/PW = 0.46; EL/EW = 0.98; EW/PW = 2.01. Body oval ( Figs 10 , 35 ). Elytra black with greenish sheen; mouthparts piceous, antennae with first antennomere black and the rest yellow; ventral side brown to black; abdomen brown. Pubescence long, moderately dense, yellowish white. Punctation dual, almost equal in diameter, dense, shallow.

Head covered with moderately long, rather dense pubescence. Antennae with 10 antennomeres ( Figs 17 ); scape about 2.5 times as long as pedicel; pedicel 1.3 times as long as wide; scarcely shorter than antennomere III. Antennomere III 1.6 times longer than wide; antennomeres IV–VI subquadrate; antennomere VII transverse. Clypeus produced anteriorly.

Prosternal process ( Fig. 8 ) 0.47 times as wide as mesoventral process, subquadrate, about 1.10 as long as wide; mesoventral process with tubercle in posterior part ( Figs 8 ), at median length of coxa 0.80 times as broad as corresponding coxal diameter.

Elytral epipleuron 3.1 times as wide as corresponding metaepisternum ( Fig. 10 ).

Abdominal postcoxal lines incomplete, recurved, V-shaped ( Fig. 18 ). Female ventrite 5 rounded; abdominal sternite VIII weakly emarginate apically with anterior part membranous ( Fig. 19 ).

Female genitalia ( Figs 20, 22 ) with proctiger (TX) truncate at apex, subtrapezoidal with basal part membranous; coxites oblique, suboval; styli absent. Bursa copulatrix not divided, simple, spermatheca not observed.

Male not examined. Male terminalia as in GORDON & ALMEIDA (1986).

Differential diagnosis. Pseudodira clypealis can be separated from the two other species by having the body black with greenish sheen ( Fig. 35 ), the V-shaped abdominal postcoxal lines and the antennae with 10 antennomeres. Moreover it has long, moderately dense pubescence on elytra, produced clypeus, the mesoventral process with a tubercle, the proctiger (TX) membranous at base, and the styli on coxites absent.

Distribution. Brazil ( Fig. 36 ).
