Xenofrea mariae sp. nov.

( Figs. 4 A‑4D)

Description: Holotype female: Integument mostly dark brown; about apical third of maxillary palpomere IV and labial palpomere III yellowish-brown; anterior area of anteclypeus and labrum reddish-brown; antennomeres III-IV reddish-brown on basal ⅔, brown on apical third; antennomeres V-XI reddish-brown basally, brown posteriorly (reddish-brown area gradually shorter toward XI). Central area of prosternal process and mesoventral process mostly dark reddish-brown. Coxae mostly dark reddish-brown; trochanters mostly yellowish-brown; femoral peduncles mostly dark reddish-brown.Wide central area of abdominal ventrites I-IV reddish-brown; base of central area of abdominal ventrite V dark reddish-brown; ventral surface of posterior third of scape, and entire ventral surface of antennomeres with moderately long, erect, sparse yellowish setae (setae gradually shorter toward XI).

Head: Frons finely, sparsely punctate; with mixed white and pale-yellow pubescence, sparser centrally between eyes.Vertex finely, abundantly punctate between antennal tubercles and area just after posterior ocular margins, densely micropunctate close to prothorax; with yellow pubescence (more yellowish-brown depending on light intensity), slightly more abundant centrally between antennal tubercles and upper eye lobes, distinctly sparser on irregular areas, absent centrally close to prothorax, with short white setae interspersed. Area behind eyes densely micropunctate; with dense yellow pubescence close to eye,with short white setae interspersed;area behind upper eye lobes close to prothorax with a few short white setae; area behind lower eye lobes with somewhat abundant pale-yellow pubescence, not obscuring integument, with short white setae interspersed. Genae nearly glabrous in frontocentral area, with white pubescence close to clypeus, with yellow pubescence with short white setae interspersed toward posterior area; with a few long, erect brownish setae.Wide central area of postclypeus with mixed white and pale-yellow pubescence not obscuring integument (mostly white anteriorly),with one long, erect dark seta on each side; sides glabrous. Labrum with a few whitish setae close to anteclypeus, with long, erect dark setae interspersed, glabrous on remaining surface, except fringe of short golden setae on anterior margin. Distance between upper eye lobes 0.70 times length of scape (0.41 times distance between outer margins of eyes); in frontal view, distance between lower eye lobes equal to length of scape (0.59 times distance between outer margins of eyes). Antennae 1.6 times elytral length, reaching elytral apex at apex of antennomere VIII.Scape slightly widened on basal third, nearly parallel-sided on posterior ⅔; with abundant mixed white and yellow decumbent setae not obscuring integument; pedicel with sparse white decumbent setae basally, and sparse, slightly distinctly yellowish decumbent setae on remaining surface; lighter area of antennomeres with white pubescence, and slightly conspicuous yellowish pubescence not obscuring integument, with white setae interspersed.Antennal formula (ratio) based on length of antennomere III: scape = 0.77; pedicel = 0.17; IV = 1.04; V = 0.69;VI = 0.57;VII = 0.54;VIII = 0.46; IX = 0.42; X = 0.38; XI = 0.42.

Thorax: Prothorax 1.5 wider than long; anterolateral angles rounded, projected; sides distinctly divergent from anterolateral angle to small, blunt central tubercle, then distinctly convergent toward posterolateral angle; with small setose tubercle behind central tubercle. Pronotum somewhat coarsely, abundantly punctate; with slight- ly distinct gibbosity on each side of anterior third; with mixed white and yellow pubescence not obscuring integument, slightly denser on some irregular areas. Sides of prothorax with sculpturing and pubescence as on pronotum (pubescence slightly denser close to prosternum); with long, erect dark seta near posterior margin. Prosternal process glabrous on centrobasal area, with abundant white pubescence on remaining surface (bristly toward its apex). Center of mesoventrite and mesoventral process with abundant white pubescence partially obscuring integument; sides of mesoventrite with shorter, sparser mixed white and yellow pubescence. Mesanepisternum and mesepimeron with abundant mixed white and yellow pubescence, partially obscuring integument. Metanepisternum with sparse mixed white and yellow pubescence. Sides of metaventrite and area near metacoxal cavities with yellow pubescence and white pubescence interspersed, yellow pubescence slightly sparser close to metaventrite; remaining surface with abundant white pubescence partially obscuring integument. Scutellum with sparse yellow pu- bescence, with white pubescence interspersed. Elytra: Obliquely, widely, slightly sulcate dorsally near apex of anterior third (more distinctly in side view), convex from this point toward apex;coarsely,abundantly punctate on anterior half, punctures slightly finer, gradually sparser toward apex, especially dorsally; apices together round- ed; with wide, oblique, partially fragmented pubescent band, from about anterior third to middle, not reaching suture or epipleural margin, pubescence mostly white centrally, yellower laterally, partially pale-yellow on some areas; area between base and oblique band with sparse yellow pubescence with short white setae interspersed; sides between oblique band and posterior seventh with yellow pubescence forming irregular patches (pubescence sparser toward epipleural margin); area along sutural margin, between oblique band and apex with yellowish-white pubescence, denser on apex (this pubescence involves the entire apex). Legs: Femora pedunculate-clavate, with dorsal area of club strongly, somewhat abruptly elevated; with mixed white and yellow pubescence dorsally and on sides of apex of club, sparser, finer, white on remaining surface. Tibiae with white pubescence not obscuring integument, sparser toward apex, except posterior ⅔ of ventral surface with yellowish-brown pubescence.

Abdomen: Ventrites with white pubescence not obscuring integument, denser on abdominal process, partially yellow laterally (more distinctly on ventrite I); ventrite V longitudinally sulcate centrally on basal third, posterior margin slightly concave.

Dimensions in mm: Total length, 6.20; prothoracic length, 1.35; anterior prothoracic width, 1.85; posterior prothoracic width, 1.70; maximum prothoracic width, 2.10; humeral width, 2.60; elytral length, 4.50.

Type material: Holotype female from BRAZIL, Espírito Santo: Sooretama, Fazenda Cupido e Refúgio , 19°03 ′ 44 ″ S, 39°58 ′ 36 ″ W, 1 male, 16.XI.2015, M. T. Tavares, S. Freitas et al., col. ( MZSP, formerly UFES).

Etymology: This species is dedicated to Dr. Maria Helena M. Galileo for her great contributions to the study of Cerambycidae .

Remarks: Xenofrea mariae sp. nov. is similar to X. ayri Santos-Silva & Galileo,2016 ,but differs as follows:oblique pubescent band of the elytra placed near middle; narrowest area of the prosternal process wider than width of the base of the profemoral peduncle; narrowest area of mesoventral process wider than half of procoxal cavity.In X. ayri , the oblique pubescent band of the elytra is basal, starting near humerus; narrowest area of the prosternal process equal to half of width of the profemoral peduncle; narrowest area of mesoventral process slightly narrower than half of procoxal cavity. It differs from X.fulgida Galileo & Martins, 2001 , by the scape shorter than antennomere III (about as long as III in X. fulgida ), and elytral punctures distinctly finer (distinctly coarser in X.fulgida ).
