description: Thraulodes rodrigoi sp. nov. (Figs. 1–7)
Diagnosis. Imago: 1) forewing with 1 weakly marked cross veins basal to bullae (Fig. 4); 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. 1); 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, 3); 5) styliger plate triangular with a medial rounded projection (Fig. 6); 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. 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. 1): 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, 2): 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. 1): 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, 5): 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, 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. 6): 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. 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: Male imago (used to take pictures), Brazil, Roraima, Alto Alegre, Floresta Nacional de Roraima, Rio Preto, 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.
