Figs 1B View Figure 1 , 3A-G View Figure 3

Length.

♂ holotype 8.4 mm; ♂ paratypes 8.0-8.4 mm (n = 3). Male holotype. Head (Figs 1B View Figure 1 , 3A View Figure 3 ): in dorsal view, strongly produced anteriorly; median length of crown approximately 9/10 of interocular width and 4/10 of transocular width; anterior margin rounded; ocelli large, located approximately on imaginary line between anterior eye angles; surface of crown slightly concave; antennal ledge, in dorsal view, slightly protuberant. Thorax (Figs 1B View Figure 1 , 3A View Figure 3 ) with pronotum, in dorsal view, with width slightly greater than transocular width of head. Forewing with base of fourth apical cell approximately aligned with base of third; with three anteapical cells, their bases obscure.

Coloration (Fig. 1B View Figure 1 ).

Head, pronotum, mesonotum, and legs pale yellow. Forewing pale yellow, translucid, preapical area with irregular orange transverse band.

Male terminalia.

Pygofer (Fig. 3B View Figure 3 ), in lateral view, with posterior margin rounded; macrosetae distributed mostly on posterior half but some located more anteriorly. Subgenital plate (Fig. 3C View Figure 3 ), in ventral view, with basal half broad and distal half very narrow; with elongate uniseriate macrosetae on basal half, microsetae distributed along outer lateral margin. Connective (Fig. 3D View Figure 3 ), in dorsal view, T-shaped; stalk carinate dorsally, shorter than one arm width. Style (Fig. 3D View Figure 3 ), in dorsal view, slender, extending posteriorly beyond apex of connective; narrowed apically, apex obtuse. Aedeagus (Fig. 3E View Figure 3 ) symmetrical; shaft short; ventral margin of shaft with preapical portion produced into robust process directed ventrally, posterior margin of process dentate; gonoduct distinct, gonopore located dorsoapically. Paraphyses slightly asymmetrical, articulated with apex of connective; elongate, extending well beyond subgenital plate apex; stalk longer than rami; in dorsal view (Fig. 3F View Figure 3 ), stalk long and robust, with pair of small dorsal processes on apical third and pair of small ventroapical processes; in lateral view (Fig. 3G View Figure 3 ), stalk slightly sinuous; rami slender, directed dorsally, narrowing towards apex.

Female unknown.

Etymology.

The name of the new species, Dasmeusa dinizi , refers to the biologist André Luis Diniz Ferreira, in recognition of his friendship to the first author and contribution as a skilled insect collector.

Type locality.

Laussat (French Guiana).

Type material.

French Guiana • ♂ holotype: "French Guiana: Laussat \ P3 \ 05°28′31.6″N- 053°35′07.3″W \ 12.ix.2010 \ Lamarre G. leg"; "White sand forest \ Light trap" (DZRJ). Paratypes • 2 ♂♂: same data as the holotype (DZRJ) • 1 ♂: "FRENCH GUIANA: Montagne \ des Chevaux \ 4°44'56″N - 52°26'28″W, alt. 75 m \ 26.vi.2011 \ window trap \ SEAG col." (MNRJ).

Taxonomic notes.

Dasmeusa dinizi sp. nov. (Fig. 1B View Figure 1 ) is similar to D. oriximina sp. nov. (Fig. 1G View Figure 1 ). These species share many similarities in the male terminalia, especially in the aedeagus and paraphyses. However, D. dinizi can be recognized by the two pairs of small processes on the paraphyses stalk (Fig. 3G View Figure 3 ), one located dorsally at the base of the apical third and another ventrally at the apex.
