391487F3262A255A58BEFB01FD35FE4D.taxon	diagnosis	Diagnosis. Among species of the “ formicaria ” species group (characterized by dense to very dense umbilicate punctures on head and pronotum, body of large size and apical maxillary palpomere elongate or conically elongate) (Márquez, 2010), R. aneba sp. nov. is similar to R. flagellicornis and R. grandipenis in the head not posteriorly narrowed, with inferior temporal carina, and ventral surface slightly convex, with dense umbilicate punctures separated by less than twice their width. However, R. aneba can be differentiated from R. flagelicornis and R. grandipenis by the proportions of antennomers, elytra to pronotum ratio, and proportions and shape of the aedeagus. In R. aneba antennomere 1 has 1.5 x the length of the antennomeres 2 – 3 combined (antennomere 1 has nearly twice the length of the antennomeres 2 – 3 combined in R. flagelicornis; and 2.06 x as long as antennomeres 2 – 3 combined in R. grandipenis) and antennomere 11 has the same size as the antennomeres 9 – 10 combined (antennomere 11 is 0.93 x shorter than antennomeres 9 – 10 combined in R. flagelicornis; and 1.06 x longer than antennomeres 9 – 10 combined in R. grandipenis). In R. aneba elytra are slightly shorter (0.94 x) than pronotum (elytra are as long as the pronotum in R. flagelicornis; and 1.08 x as long as pronotum in R. grandipenis). The elytra slightly shorter than pronotum is not a common character in Renda species, it is shared only by R. brachyptera in this species group. The total length of the aedeagus of R. aneba is 2.16 mm (3.55 mm in R. flagelicornis; and 4.24 mm in R. grandipenis). In R. aneba the aedeagus parameres are 0.83 x the length of the median lobe (0.39 x the length of the median lobe in R. flagelicornis; and 0.29 x in R. grandipenis), making this character very distinctive of this new species, which has the longer parameres of all species of the group, even of all species of Renda.

The vegetation in the area is Evergreen Tropical Forest “ Floresta Ombrófila Densa de Terras Baixas ” (Veloso et al. 1991). Distribution. Renda aneba sp. nov. is known only from the type locality, from a collection point 2 km from the right bank of the Rio Anebá, in the municipality of Silves, Amazonas state, Brazil. Etymology. The specific epithet refers to the name of the river (Rio Anebá) near the collection site of the holotype. Anebá is an indigenous word, from the Tupi language, which means “ back ”, “ return ” or “ to return ”. The specific epithet name is a noun in apposition.	en	Klemann-Junior, Louri, Barroso, Paulo Ricardo Ramires, Márquez, Juan (2025): New species and new records of Renda Blackwelder, 1952 (Coleoptera: Staphylinidae: Xantholinini) from Brazil, with an updated key to the species of the genus.

391487F3262D255758BEFD89FE94FE15.taxon	diagnosis	Diagnosis. Among species of the “ minor ” species group (characterized by fine, moderately dense punctures on pronotum, except for wide longitudinal impunctate area; body mainly black; and apical maxillary palpomere conical) (Márquez, 2010), R. boiuna sp. nov. is similar to R. mesoamericana in the reddish-brown coloration of the genital segment and posterior border of pregenital segment of abdomen; head with temple flattened; and aedeagus large, oval elongate. However, R. boiuna can be differentiated from R. mesoamericana by the shape of the head; by the size and distribution of the punctures on the ventral surface of the head; and by the aedeagus. In R. boiuna the head has parallel lateral margins, behind the eye line, and the posterior border is straight, giving the head a square shape. In R. mesoamericana the lateral margins of the head smoothly converge posteriorly and the posterior border is slightly rounded, giving the head a square oval shape. In R. boiuna umbilicate punctures on the ventral surface of the head are larger than on the lateral and dorsal surfaces (same size in R. mesoamericana); ventral surface of head with umbilicate punctures not evenly distributed in R. boiuna (umbilicate punctures evenly distributed in R. mesoamericana). The median lobe of the aedeagus of R. boiuna has a narrow and well-marked neck just below the insertion of the parameres, this neck is absent in R. mesoamericana. The aedeagus of R. boiuna has the left paramere smaller than the right paramere, while in R. mesoamericana the right paramere is smaller than the left paramere. Description.
