Thraulodes rodrigoi  sp. nov. ( Figs. 1–7View FIGURES 1–3View FIGURES 4–7)

Diagnosis. Imago: 1) forewing with 1 weakly marked cross veins basal to bullae ( Fig. 4View FIGURES 4–7); 2) costal and subcostal areas of forewing opaque; 3) femora of forelegs with an apical transversal band brown heavily marked and one submedian macula ( Fig. 1View FIGURES 1–3); 4) tergum I washed with reddish brown; terga II–VI with a medial reddish brown band on posterior margin; terga VII, IX and X reddish brown with lateral areas white ( Figs. 1, 3View FIGURES 1–3); 5) styliger plate triangular with a medial rounded projection ( Fig. 6View FIGURES 4–7); 6) penes short and wide, without lateral pouch; penes spines short, with 1.56x the width of penes base, with base robust, tapering to apex ( Fig. 7View FIGURES 4–7).

Male imago: Length of body: 6.2–6.3 mm; forewings: 7.0 mm; hind wings: 1.3 mm. General color whitish with reddish brown areas.

Head ( Fig. 1View FIGURES 1–3): Reddish brown. Scapes and pedicels light brown. Ocelli white, surrounded by a dark brown ring at base. Eyes black, turbinate portion reddish.

Thorax ( Figs. 1, 2View FIGURES 1–3): Pronotum brown, scutellum dark brown; meso- and metanotum light brown. Prosternum whitish; mesosternum white, anterior region brown; metasternum brown with median region darker.

Legs ( Fig. 1View FIGURES 1–3): All legs with coxae whitish; fore femur with a strongly marked apical reddish brown band, and a submedian reddish brown maculae; mid and hind femur with a strongly marked subapical reddish brown band; tibia and tarsi washed with light brown.

Wings ( Figs. 4, 5View FIGURES 4–7): Membrane of wings hyaline with reddish brown stain at base. Membrane between C and Sc of forewings opaque. Forewings with one cross vein weakly marked basal to bullae and 10 distal to bullae.

Abdomen ( Figs. 1, 3View FIGURES 1–3): segments predominantly translucent white; two lateral reddish brown spots on terga II–VI; tergum I washed with reddish brown; terga II–VI with a medial reddish brown band on posterior margin; terga VII, IX and X reddish brown with lateral areas white. Caudal filaments yellowish white, with reddish brown annulations.

Genitalia ( Fig. 6View FIGURES 4–7): Styliger plate triangular, with a medial rounded projection. Forceps yellowish, with strong constriction on the middle of segment I. Penes short and wide, without lateral pouch; penes spines short, 1.56 x the width of the medial region of the penes, with base robust, tapering to apex ( Fig. 7View FIGURES 4–7).

Etymology. The specific epithet honors Rodrigo Lopes Borges, a student who devoted himself to entomology during his undergraduate studies but passed away due to cancer.

Distribution. Roraima State, Brazil.

Material Examined. Holotype:GoogleMaps  Male imago (used to take pictures), Brazil, Roraima, Alto Alegre, Floresta Nacional   GoogleMaps de Roraima, Rio Preto   GoogleMaps, light trap, 02°56’18.05’’N / 61°37’27.28’’W, 18-22.xii.2017, Boldrini, R., Oliveira, I.B., Barbosa, F.S., Almeida, M.L.S., Picanço, M.M. and Xavier, F.F. leg. Paratype: male imago, same data as holotype (wings, legs and genitalia mounted on slides).

Comments. Thraulodes rodrigoi  sp. nov. resembles T. flinti Domínguez, 1987  in having a triangular styliger plate and short, broad penes with lateral pouch absent, forewings with cross veins basal to bullae, and fore femur with a strongly marked apical band and with a submedian maculae. Nevertheless, imagos of T. rodrigoi  sp. nov. can be distinguished from T. flinti  by the shape of forceps, segment I with strong constriction on the middle in T. rodrigoi  , while segment I has a constriction on basal 1/3 of segment I in T. flinti  . and T. flinti  has 4 weakly marked cross veins basal to bullae, while the new species has only one.
