( Figs. 1 , 3 )

Diagnosis. Euphoria euridesi sp. nov. has bifurcated clypeus, with two apical teeth that are bent upwards ( Fig. 1C ), differing from E.lurida which lacks the clypeal teeth ( Fig. 2C ). The head and pronotum of E. euridesi are sparsely to densely setose (F Fig. 1 A-E) and the surface of body is usually all black ( Fig. 1 A-E).

Description. Holotype. Male. Size: length: 15- 11 mm width: 8- 6 mm. Color: Surface shiny, black with yellowish setae. Head: Clypeus bifurcated, with two apical teeth, that are bent upwards ( Fig. 1 A-D); weakly setose, with short setae ( Fig. 1C ); clypeolateral declivity weakly raised. Frons punctate, sparsely to densely setose; setae moderately long to long ( Fig. 1C ). Canthus and antennal scape setose ( Fig. 1C ). Pronotum: Surface moderately punctate; punctures more concentrated near the margins, evident by the setae that project from these punctures ( Fig. 1 C-E). A tomentose band on lateral margin and a second inner band adjacent to it; the second band frequently reduced (1 C-E). Scutellum longer than wide, impunctate ( Figure 1A ). Elytra: Margin of the disc slightly transverse anterioly and rounded posteriorly; with one humeral umbone and one anteapical umbone on each elytron; Two parallel elevated longitudinal costae along the center of each elytron. Longitudinal sutural costa present. Posterior half of costae distinctly raised in lateral view ( Fig. 1A , D-E). The surface is fully covered with c-shaped punctures and irregular punctures. Surface sparsely setose, setae short. Presence of small to moderately large, reniform, vermiform, or irregular yellowish tomentose dorsal markings ( Fig. 1A , D-E). Thoracic venter: Hypomerum: Strongly concave below on the posterior half; surface rugose or convergently striate, and setose. Prosternum: Strongly setose anteriorly, with long setae. Mesoventrite: rugose or differently punctate, with short setae. Mesometaventral process: extended beyond mesocoxae, process glabrous on mesosternal lobe, apex rounded, flat ( Fig.1B ). Mesepisternum: with short setae. Mesepimeron:rugose, strongly setose. Metaventrite with a median sulcus evident, flat, impunctate and glabrous centrally ( Fig.1B ); laterally surface brownish, with yellowish tomentose markings, rugose and setose; anteriorly setose. Metepisternum with brownish surface, rugose and setose, with yellowish tomentose markings. Metepimeron punctate and with short setae on the side of the elytra. Legs: Tarsi with setae on the tarsomeres; the terminal tarsomere longer than the others. Protibia with three lines of setae dorsally, and one line of setae laterally; sparsely setose ventrally; one spur apically and three equidistant denticles: one apical-lateral, and two lateral-proximal, the latter, reduced.Profemur with lines of long setae dorsally and laterally, and sparsely setose ventrally. Mesotibia shorter than the Metatibia, both with two spurs apically; three apical denticles, presenting a superficially rough concavity between the apical pair and one proximal denticle, that is reduced on the metatibia; a dorsal line of long setae, and sparse setae. Metafemur wider than Mesofemur, both having two setose sulci dorsally, sparsely setose on surface striations. Surface of Procoxa and Mesocoxa punctate and setose, with setae longer on procoxa and trochanter. Metacoxa striated, brownish, with sparse setae. Abdomem: Six visible ventrites, with two yellowish tomentose markings in the first five ventrites; sparsely setose laterally, glabrous centrally; setae long to moderate ( Fig. 1B ). Pygidium: Surface rugose, with moderately short setae; covered by two yellowish tomentose markings. Aedeagus: Parameres long and parallel, with square tips, without spines or hooks ( Fig. 1F, G ).

Morphological variation. Surface shiny, occasionally light brown, dark brown or reddish brown. Pronotum with second inner tomentose band often reduced to a few markings. Abdominal shape in lateral view similar in both sexes.

Geographic distribution. E. euridesi sp. nov. is known from Brazil occuring in Cerrado and Parana Forest provinces ( Fig. 3 ).

Etymology. The specific epithet is a tribute to the memory of Eurides Furtado, friend, pioneer of Entomology in the State of Mato Grosso, important lepidopterist, and major contributor to the CEMT collection, which now bears his name, as a tribute to his legacy.

Remarks. Although we did not encounter any, specimens of E. euridesi sp. nov. having the clypeus worn away probably exist, which could lead to confusion with E. lurida . However, such specimens should be distinguishable because the clypeal teeth, being projected upwards, form an evident clypeal concavity. Additionally, the two species’ geographical distribution is largely different.
