Pseudoryssomus brulei sp. nov.

(Fig. 8)

Description of holotype (male). Length 3.73, width 2.82 mm. Form elongate oval, widest at middle of elytra, not flattened dorsoventrally (Fig. 8C). General color yellowish red, thorax and abdomen dark brown medially (Fig. 8A). Outline of pronotum and elytron discontinuous. Pronotum yellowish red, with a basal black spot, translucent at apex; finely, densely punctured; pubescence of semidecumbent yellowish hairs (Fig. 8D). Elytra yellowish red, with a large black sutural spot, not reaching the humeral callus, narrowed in the middle, irregularly widening towards the apex, not reaching elytral margin; each elytron with irregularly oval lateral spot on the posterior half. Elytral punctures intermixed coarse and fine, dense, slightly larger than on pronotum and sparse in the discal area. Antenna and mouthparts brownish yellow, hypomera and epipleura yellow, legs brownish yellow. Metaventrite finely, sparsely punctured medially and anteriorly; coarsely, densely punctured laterally and posteriorly with punctures large, often confluent (Fig. 8B). Abdominal ventrites coarsely punctured, punctures separated by about a diameter or less, punctures becoming coarser laterally. First abdominal ventrite with postcoxal line complete, extending beyond middle of first ventrite; precoxal area coarsely punctured on base of cavity (Fig. 8E). Genitalia simple; basal lobe shorter than paramere, lateral margin slightly thickened, apex bluntly pointed; paramere slightly curved in lateral view, nearly parallel-sized (Fig. 8G, H); sipho very sinuous at apex (Fig. 8F).

Female. Genitalia with genital plates triangular, elongate, styli with setae (Fig. 8I); spermatheca unobserved.

Etymology. This species is named in honor of Dr. Stéphane Brûlé, one of the most enthusiastic members of the French Guiana project.

Discussion. The elytral color pattern is distinctive for Pseudoryssomus brulei sp. nov. Although somewhat similar to P. crucifer sp. nov. and P. triangulus sp. nov., the spots are differently shaped and the male genitalia with sipho sinuous at apex.
