Description. Male. Integument light brown, legs slightly lighter, apical half of antennomere V and antennomeres VI–XI dark.

Head. Dense and coarsely punctate; upper eye lobes very reduced and well-separated. Last segment of maxillary palpi strongly thickened, abruptly narrowed at apex. Antennae reaching elytral apex at base of antennomere VII; antennomeres finely and densely punctate, with short and dense yellowish setae, interspersed with longer setae; inner face of antennomeres IV–XI with long, dense black setae; scape slightly curved at base, progressively dilated to apex; antennomeres III–VIII gradually thickened; antennal formula (ratio) based on length of antennomere III: scape = 1.33; pedicel = 0.10; IV = 1.00; V = 1.08; VI = 1.13; VII = 0.97; VIII = 0.79; IX = 0.64; X = 0.49; XI = 0.46.

Thorax. Prothorax transverse, 1.38 times wider than long (including lateral tubercles), densely and coarsely punctate, with some sparse, short whitish setae; lateral tubercles small, slightly projected and placed before middle. Prosternal process thin, subparallel-sided, slightly narrowed at middle, apex truncated. Elytra very coarsely confluently punctate throughout; each elytron with two distinct carinae, starting at base, innermost nearly reaching apex, outermost reaching apical sixth; setae rather short, bristling, aligned in four longitudinal rows and entire external margin; elytral apex rounded.

Abdomen. Ventrites finely punctate, with moderately long, dense whitish setae (denser laterally), disappearing gradually on central region toward ventrite V.

Dimensions (mm). Holotype male. Total length, 5.1; prothoracic length, 0.9; basal prothoracic width, 0.8; distal prothoracic width, 0.8; widest prothoracic width (between apices of lateral tubercles), 1.0; humeral width, 1.1; elytral length, 3.5. Paratypes male (n=12). Total length, 5.28±0.26; prothoracic length, 0.90±0.05; basal prothoracic width, 0.77±0.05; distal prothoracic width, 0.78±0.06; widest prothoracic width (between apices of lateral tubercles), 0.96±0.04; humeral width, 1.14±0.08; elytral length, 3.50±0.18.

Type material. Holotype male from BRAZIL, Espírito Santo: Linhares , male, IX.1972, B. Silva col. DZUP469264 ( DZUP) . Paratypes. BRAZIL, Espírito Santo: Linhares , male, X.1971, B. Silva col. DZUP469262 ( DZUP) ; Linhares (Parque Sooretama), 6 males, X.1963, F.M. Oliveira col. (2 MZSP; 4 DZUP: DZUP469263 , DZUP469265 , DZUP469268 , DZUP469269 ) ; 2 males, XI.1967, F.M. Oliveira col. (1 MNRJ; 1 DZUP: DZUP469270 ) .

Etymology. This species is named in honor of Maria Helena Galileo, one of the most enthusiastic Cerambycidae researchers, for his contributions to the knowledge of the Neotropical Cerambycidae .

Remarks. Villiersicometes galileoae sp. nov. differs from V. scellierae Dalens, 2013 as follows: body not covered with sparse decumbent setae; disc of pronotum and elytra concolorous; and elytra unicolorous, without dark stripes or maculae. In V. scellierae , the whole body is covered with sparse decumbent whitish setae, disc of the pronotum is darker than elytra, and the elytra have a transverse dark macula on middle of the apical half. The new species differs from V. wagneri (Gounelle, 1911) by the uniformly light-brown body (in V. wagneri , the head, thorax and scutellum are dark brown and the elytra is greenish). Villiersicometes galileoae differs from V. bijubatus (Gounelle, 1911) by the light-brown coloration of the body, and the setae of the elytra shorter (in V. bijubatus , the coloration of the body is darker, and the setae of the elytra are longer). The new species differs from V. lineatus ( Villiers, 1958) by the disc of the pronotum and elytra concolorous (in V. lineatus , the disc of the pronotum is darker than the elytra).
