Diagnosis. Among species of the G. cicatricosa group (with size≥ 3.5 mm and relatively long antenna) G.curupira sp. nov. is similar to G. opacum in size and the totally matt surface. However, G. curupira can be differentiated from G. opacum by the size of the punctures of the head, pronotum and elytra, size of the interstices between the punctures, by the shapes of the antennomeres, and by the distinctive shape of the aedeagus. In G. curupira the size of the punctures on the head and pronotum are subequal to punctures on the elytra (the largest punctures on the head and pronotum are the same size as the smallest punctures on the elytra); in G. opacum punctures on the elytra are much larger than those on the head and pronotum. In G. curupira punctures on clypeus smaller and sparser than on vertex; in G. opacum the clypeus is more sparsely punctate and the punctures equal in size to those of the vertex. In G. curupira the interstices between the punctures on the head, pronotum, and elytra vary from 1/2 to 1/5 as wide as the diameter of the punctures; in G. opacum the interstices between the punctures are less than 1/4 as wide as the diameter of the punctures on the head, the interstices are indistinct and irregular on the elytra. In G. curupira , antennomeres 5–10 are slightly wider than long, the length of the setae are about 0.9 the width of the antennomeres; in G. opacum , antennomeres 5-10 are quadrate or slightly longer than wide, and the setae are half as long as the width of the antennomeres. The apical part of the median lobe of the aedeagus of G. curupira broader (in lateral view) than the apical part of the median lobe of G. opacum . The median lobe of G. curupira has sensilla; sensilla are absent in G. opacum . The paremeres of the aedeagus of G. curupira are strongly curved in lateral view and without sensilla; the parameres are straight and has two sensilla at the base in G. opacum .

Description. Holotype male, BL: 4.0 mm, FL: 2.01 mm.

Coloration: dark reddish brown (almost black); antennae dark reddish brown (almost black); legs light reddish brown.

Head ( Figure 1A View FIGURE 1 ) wider (HW: 0.64) than long (HL: 0.54); subrectangular; with rounded hind and anterior angles; large eyes slightly prominent and longer than temples; sides in front of eyes parallel up to base of antennae; at base of antennae with almost rectangular angle; anterior edge of clypeus as wide as half of width between base of antennae. Head with large, dense and deep setiferous punctures; with some coalescent punctures without evident ridges; each puncture with a yellow seta; interstices between punctures 1/2 to 1/5 as wide as diameter of punctures. Integument of epicranium, including surface of punctures, covered by dense microsculpturing formed by uniformly distributed micropunctures, appearing matt. Punctures on clypeus smaller and sparser than on vertex, surface matt. Neck appearing matt due to dense microsculpturing formed by uniformly distributed micropunctures; microsculpture on neck larger than microsculpture on head, pronotum, elytra, and abdomen. Antenna ( Figure 1B View FIGURE 1 ) slightly longer than head, pronotum and half of elytra together; antennomeres 2–10 gradually and smoothly widening anteriorly; antennomere 1 subrectangular, long and thick; antennomere 2 narrower (0.8) and shorter (0.45) than antennomere 1; antennomeres 3–4 wider than long, wider than antennomere 2 and narrower than antennomere 1; antennomeres 2–10 slightly wider than long; antennomere 11 narrower and longer than antennomere 10; all antennomeres with numerous long yellow setae; setae slightly shorter (0.9) as width of antennomeres.

Pronotum ( Figure 1A View FIGURE 1 ) quadrate (PL: 0.60; PW: 0.60); widest at anterior third; anterior lateral margins convergent to widely rounded anterior angles in smooth convex curve; posterior lateral margins convergent to obtuse posterior angles in smooth concave curve; anterior margin straight. Pronotum with large, dense and deep setiferous punctures; some coalescent punctures without evident ridges; each puncture with a yellow seta; punctures as dense and deep as punctures on head; interstices between punctures 1/2 to 1/5 as wide as diameter of punctures. Median carina in wide depression; carina well developed for most of length, absent or weak anteriorly. Integument of pronotum, including surface of punctures, with similar dense microsculpturing formed by uniformly distributed micropunctures as head, appearing matt.

Elytra ( Figure 1A View FIGURE 1 ) wider than pronotum, longer than wide (EL: 0.87; EW: 0.82); sides slightly convex; widest at middle; shoulders well developed, smoothly curved and shortly denticulate; posterior angles rounded; humeral angles of elytra strongly extended anteriorly. Elytra with large, dense and deep setiferous punctures; smaller punctures of elytra about equal to larger punctures on head and pronotum; punctures each with a yellow seta; setae in asymmetric position to center of punctures; interstices of punctures 1/2 to 1/4 as wide as diameter of punctures. Discal carina distinct; curved outward, following the lateral margin of elytra. Lateral carina indistinctly restricted shortly behind shoulders. Suture marked by line of small, shallow and coalescent punctures along entire length of elytra. Space between suture and discal carina with presence of three irregular and parallel rows of setiferous punctures along entire length of elytra; with some coalescent punctures without evident ridges. Laterally to discal carina another two irregular and parallel rows of setiferous punctures along entire length of elytra; submarginal surface with two rows of slightly smaller setiferous punctures. Integument of elytra, including carina and surface of punctures, with similar dense microsculpturing formed by uniformly distributed micropunctures as head and pronotum, appearing matt.

Legs ( Figure 1A View FIGURE 1 ) almost completely covered with short yellow setae; surface appearing matt, with microridges organized with cells.

Abdomen with dense and large setiferous punctures; each puncture carrying yellow seta; punctures becoming less deep from segments 3 to 8; punctures on segments 7 and 8 much less deep. Interstices between punctures in segment 3 similar to head, pronotum and elytra; interstices between punctures becoming larger from segments 3 to 8. Surface of abdomen with similar dense microsculpturing formed by uniformly distributed micropunctures as head, pronotum and elytra, appearing matt.

Aedeagus as in Figure 1C View FIGURE 1 . In lateral view, paramere small and strongly curved, with its apex reaching half of median lobe; with short acute apex and without sensilla. Median lobe in lateral view curved, bulbous at base, apical region distinctly bigger than middle region; apex with small pointed to parameral side and with numerous sensilla in apical 2/3 region.

Female similar to male.

Variation. Total length 3.7 to 4 mm. Coloration, punctures pattern on the head, pronotum and elytra, and shapes of the antennomeres were consistent among the specimens examined.

Habitat. Captured manually under bark in decaying trunks and branches. The capture sites are destined for selective logging and the vegetation is second-growth Evergreen Tropical Forest “Floresta Ombrófila Densa de Terras Baixas” ( Veloso et al. 1991).

Distribution. G. curupira sp. nov. is know from the municipalities of Itacoatiara and Itapiranga in Amazonas State, Brazil.

Etymology. The specific epithet name is a noun in apposition and refers to a figure from Brazilian folklore (Curupira), of Amazonian origin, characterized as an entity that protects the forests. In a local legend (see Chaves 2021), at the exact point where the holotype of the species was collected, workers from a logging company reported having been terrorized by this folkloric figure after a day of work in the forest.
