Diagnosis.

No reliable external characters have been found to distinguish Renodaeus gibbicollis from the other species of the genus. The left paramere (Fig. 286, after Carvalho and Becker 1959), lacking a hook at the apex of the right process, and the C-shaped right paramere (Fig. 288, after Carvalho and Becker 1959) will separate it from Renodaeus mimeticus .

Description.

Male (measurements after Carvalho and Becker 1959): Length 2.40 mm, width 0.75 mm. Head: Width 0.66 mm, interocular width 0.24 mm. Labium: Length (not given). Antenna: Segment I length 0.18 mm, II, 0.55 mm, III, 0.35 mm, IV 0.30 mm. Pronotum: Length (not given), basal width 0.60 mm.

Female (n = 1): Length 2.45 mm, width 0.93 mm. Head: Width 0.77 mm, interocular width 0.30 mm. Labium: Length 0.77 mm. Antenna: Segment I, length 0.19 mm; II, 0.53 mm; III, 0.32 mm, IV missing. Pronotum: Length 0.53 mm, basal width 0.67 mm.

Coloration: Head: Dark brown. Antenna: Segment I pale brown, with a red streak on outer margin; segments II and III dark brown; segment IV missing. Pronotum: Uniformly dark brown. Scutellum: Dark brown. Hemelytron: Dark brown; membrane dark smoky brown. Ventral surface: Thorax dark brown; abdomen dark reddish brown. Legs: Fore and middle coxa reddish brown, hind coxa pale; femora dark reddish brown, apex of hind femur pale; tibiae dark brown, with apical thirds pale yellowish brown; tarsi and claws pale yellowish brown.

Structure, texture, and vestiture: Head: Shiny, smooth, impunctate. Labium: Extending to bases of middle coxae. Pronotum: Polished, impunctate; weakly swollen, hind margins flared; with scattered, short, recumbent simple setae. Scutellum: With a thick band of silvery, scale-like setae through middle, intermixed with a few long erect simple setae. Hemelytron: Shiny throughout; sparsely and finely punctate on apical half of corium; densely and coarsely punctate on clavus and basal half of corium; with two bands of silvery, scale-like setae, one across base of corium and clavus (and extending across scutellum) and one across middle or corium and apex of clavus; area between silvery bands densely covered with golden, scale-like setae; corium (one or two scattered) and clavus (one row of three or four) with few, pale, bristle-like setae. Ventral surface: Shiny, with a few scattered erect and semierect, simple setae.

Male genitalia (redrawn after Carvalho and Becker 1959): Left paramere (Fig. 286) with a broad quadrate main body with a curving right arm. Right paramere (Fig. 288) C-shaped, upper arm more slender than basal one. Phallotheca (Fig. 287) relatively simple, cone-shaped.

Distribution.

Described and known only from British Guiana (now Guyana).

Host.

Unknown.

Discussion.

Although the female of Renodaeus gibbicollis is similar to Renodaeus mimeticus , the male genitalia illustrated by Carvalho and Becker are considerably different from those of this new species.
