Diagnosis. Among species of the “fimetaria ” species group (characterized by dense umbilicate punctures on head; pronotum with dense to moderately dense fine punctures, except for wide longitudinal impunctate area; apical maxillary palpomere elongate to conically elongate; body mainly black; apical antennomere as long as, or shorter than antennomeres 9–10 combines; labrum slightly bilobed; without fascia on elytra; and apical labial palpomere slightly widened and flattened toward apex) ( Márquez, 2010), R. carauariense sp. nov. is the only one with shallow umbilicate punctures on the pronotum and with a wide longitudinal impunctate area in the midline of the pronotum (approximately 1/4 the width of the pronotum at the widest part). Also, R. carauariense is the only one with umbilicate punctures on the elytra similar to pronotum, but denser than it. Furthermore, R. carauariense can be differentiated by the size, proportions, and sclerotization of the aedeagus.

Description. Holotype male, BL: 11.00– 12.28 mm, FL: 6.32–6.47 mm.

Coloration: Head black, with anterior border dark reddish brown; pronotum and elytra black; abdominal segments 3–6 black, with posterior border dark reddish brown; abdominal segments 7–8 black, with posterior 1/5 yellow to reddish brown; abdominal segment 9 yellowish; antennomeres 1–10 dark reddish brown; antennomere 11 dark reddish brown, with anterior half lighter; mandibles dark reddish brown; labial and maxillary palps reddish brown; legs reddish brown to dark reddish brown, with tarsomeres reddish brown.

Head ( Figs. 5B, 5C View FIGURE 5 , 6B View FIGURE 6 ) oval; longer (HL: 1.85–1.91 mm) than wide (HW: 1.47–1.51 mm); not posteriorly narrowed; dorsal and ventral surfaces clearly convex. Dorsal surface of head ( Fig. 5B View FIGURE 5 ) with dense umbilicated punctures, extending to near anterior border. Ventral surface ( Fig. 5C View FIGURE 5 ) with sparse umbilicated punctures (2 punctures in 0.3 mm); some areas without punctuation; largest punctures near center of head ( 0.07 mm), becoming smaller towards lateral margins and posterior border ( 0.04 mm); each puncture with long seta, brown at base and yellow at tip; interstices between punctures 0.25 to 1.71x the diameter of largest punctures; shiny. Temple with superior and inferior temporal carina, and slightly concave area ( Fig. 6B View FIGURE 6 ). Eyes ( Fig. 5B View FIGURE 5 ) 0.28–0.30x head length (OL: 0.54–0.56 mm, OW: 0.25–0.28 mm), interocular distance 0.60–0.64x head width (IO: 0.90–0.97 mm). Antennomere 1 with 1.95x the length of antennomeres 2–3 combined; antennomeres 1–3 longer than wide, club-shaped; antennomeres 4–10 wider than long, gradually becoming wider from 4 to 10; antennomere 11 as wide as long, 0.85x length of antennomeres 9–10 combined; antennomeres 1–11 ( Fig. 6A View FIGURE 6 ) with numerous brown/yellow macrosetae, macrosetae becoming smaller from antennomere 1 to 11; antennomeres 4–11 densely covered by yellow microtrichae. Labrum slightly bilobed; mandibles with external channel.Apical maxillary palpomere elongated, 1.71x length of pre-apical palpomere. Apical labial palpomere slightly widened toward apex, 2.14x as long as preapical palpomere.

Pronotum ( Fig. 5D View FIGURE 5 ) 1.55–1.63x longer (PL: 2.34–2.46 mm) than wide (PW: 1.50–1.55 mm); wider in the middle; 1.00–1.03x head width; anterolateral margins convergent in a smooth convex curve; posterolateral margins convergent to posterior angles in a smooth concave curve; narrow and straight anterior border; wide and rounded posterior border. Pronotum with shallow umbilicated punctures; giving the impression of thin, sparse punctures; midline with wide longitudinal impunctate area (approximately 1/4 the width of the pronotum at the widest part); each puncture with long seta, brown at base and yellow at tip; interstices between punctures less than 3x the diameter of punctures; shiny. Posterior half of pronotum with well-developed depressed area on each side of posterior third.

Elytra ( Fig. 5E View FIGURE 5 ) 1.49x wider than pronotum (EL: 2.25–2.35 mm); as long as wide (EW: 2.25–2.38 mm); as long as pronotum. Elytra with umbilicated punctures similar to pronotum; punctures denser than pronotum; interstices between punctures less than 0.5x diameter of punctures; each puncture with long brown seta; shiny.

Legs ( Fig. 5A View FIGURE 5 ) shiny; femur with long setae, brown at base and yellow at tip; tibia with long, yellow setae, denser than femur; tarsi with long, yellow setae, less dense than tibia; tibia with spines on outer margin and on apical border. Prolegs shorter than meso- and metalegs; tarsi with slight lateral expansion.

Abdomen ( Fig. 5A View FIGURE 5 ) shiny; segments 3–5 approximately the same width, slightly less wide than elytra; with small, dense punctures, denser than the elytra; covered with dense long brown setae; setae denser than elytra, head, and pronotum. Apex of sternum 8 slightly concave.

Aedeagus ( Figs. 6D–G View FIGURE 6 ) oval elongated, with constricted lateral margins; total length 1.46–1.56 mm. Parameres 0.48x length of median lobe. Apical area of median lobe 0.22x total length of median lobe; internal sac with sclerotized structures. Basal part of median lobe thin, malleable and transparent; with only a tubular structure visible.

Female unknown.

Habitat. Collected with Flight Intercept Trap, installed on the ground, and baited with fresh human feces and rotten fish. The vegetation in the area is Evergreen Tropical Forest “Floresta Ombrófila Densa de Terras Baixas” ( Veloso et al. 1991).

Distribution. Renda carauariense sp. nov. is known only from the type locality, from a collection point 6 km from the right bank of the Rio Juruá, in the municipality of Carauari, Amazonas state, Brazil.

Etymology. The specific epithet refers to the name of the municipality (Carauari) where the species was collected. The specific epithet name is a noun in apposition.
