Carinojassus guianensis View in CoL sp. nov.

( Figs 1−30 View FIGURES 1–15 View FIGURES 16–26 View FIGURES 27–32 )

Diagnosis. Male sternite VIII ( Fig. 5 View FIGURES 1–15 ) with ventral surface covered by robust setae and posterior margin broadly rounded. Style ( Figs 9, 10 View FIGURES 1–15 ) sinuate; with ventral digitiform process at middle third. Aedeagus ( Figs 11−13 View FIGURES 1–15 ) short; with shaft compressed laterally and tapered; apex rounded. Male anal tube ( Figs 14, 15 View FIGURES 1–15 ) with pair of linear and separate dorsal connectives. Female sternite VII ( Fig. 21 View FIGURES 16–26 ) with posterior margin deeply excavated medially.

Type locality. Montagne des Chevaux, French Guiana.

Measurements. (mm). Total length, 7.0−7.4 (males), 8.5 (female).

Color. Dark reddish-brown, female darker than males ( Figs 27−30 View FIGURES 27–32 ). Forewing of male ( Fig. 4 View FIGURES 1–15 ) brown with red veins; apical region and appendix smoky. Forewing of female ( Fig. 19 View FIGURES 16–26 ) dark brown with dark brown veins at basal half and red at apical half; with five light yellow spots, two smaller at proximal portion of R and M veins and three larger at distal portions of R, M, and Cu veins; apical portion and appendix smoky. Hind wing ( Fig. 20 View FIGURES 16–26 ) dark brown, except by light brown costal region; veins dark brown, except by light brown R vein and pale crossvein m-cu.

Description. External morphological characters as in generic description.

Male terminalia. Sternite VIII ( Fig. 5 View FIGURES 1–15 ), in ventral view, approximately as long as wide; ventral surface covered by robust setae; lateral margins slightly sinuous; posterior margin broadly rounded. Pygofer ( Fig. 6 View FIGURES 1–15 ), in lateral view, short, height approximately 1.7 times of the length; posterior margin truncated; macrosetae distributed only near posterior margin. Valve ( Fig. 7 View FIGURES 1–15 ), in ventral view, 1.2 times wider than long; posterior margin deeply excavated medially. Subgenital plate ( Fig. 6 View FIGURES 1–15 ), in lateral view, not surpassing the apex of pygofer; in ventral view ( Fig. 8 View FIGURES 1–15 ), ligulate; about 3 times longer than wide; ventral surface covered by robust macrosetae; external margin approximately rectilinear, internal margin broadly convex; apex acutely rounded. Connective ( Fig. 9 View FIGURES 1–15 ) approximately one-third of length of style. Style ( Fig. 9 View FIGURES 1–15 ), in dorsal view, with outer lobe well-developed and rounded; in lateral view ( Fig. 10 View FIGURES 1–15 ); enlarged medially, with a ventral digitiform process at median third; apex rounded, slightly curved dorsally. Aedeagus ( Figs 11−13 View FIGURES 1–15 ) short, with shaft compressed laterally and tapered, directed posterodorsad; apex rounded. Dorsal connective ( Figs 14, 15 View FIGURES 1–15 ) paired connecting base of aedeagus to segment X of anal tube; each linear, short and narrow, ventral portion slightly curved anteriorly.

Female terminalia. Sternite VII ( Fig. 21 View FIGURES 16–26 ), in ventral view, subrectangular; 1.5 times wider than long; lateral margins approximately rectilinear and converging posteriorly; posterior margin deeply excavated medially. Internal sternite VIII membranous. Pygofer ( Fig. 22 View FIGURES 16–26 ), in lateral view, short; about 2.5 times higher than long; apex slightly concave; posterior margin broadly rounded. First valvula ( Fig. 23 View FIGURES 16–26 ) curved dorsally; about 13.5 times longer than high; with approximately same height along its entire length; apex ( Fig. 24 View FIGURES 16–26 ) acutely rounded. Second valvula ( Fig. 23 View FIGURES 16–26 ) similar to first valvula in length and curvature; apical portion ( Fig. 25 View FIGURES 16–26 ) dorsal margin with very small preapical denticles; apex rounded with margin crenulate. Second valvifer ( Fig. 26 View FIGURES 16–26 ) higher than long. Third valvula ( Fig. 26 View FIGURES 16–26 ) 3.5 times longer than high; with sparse setae near ventral margin; apex rounded.

Etymology. The species name is in reference to the country where specimens were collected.
