Male. Integument generally brownish red. Body covered with long whitish setae. Elytra brownish red with two pairs of eburneous callosities: one pair of rounded callosities in median region, and one pair of oval callosities near suture in apical third.

Frons with brownish setae. Vertex with coarse dense punctures; long, moderately dense and yellowish setae. Antennal tubercle with fine shallow punctures, dense at apex; short dense yellowish setae. Dorsal region of head with coarse and dense punctures. Upper eye lobes well separated, distance between them at most 1.5 times width of upper lobe; lower eye lobes about twice width of upper lobes. Genae about 1/3 as long as diameter of lower eye lobes, with long brownish setae. Antennae exceeding elytral apices at most by four antennomeres; pedicel and antennomeres III–XI with fine, deep, dense punctures; median, dense brownish setae; apices of antennomeres III–V smooth and glabrous; antennomeres III–V filiform and VI–XI wider and serrate, more evident in apical antennomeres; antennomere III flattened dorso-ventrally; antennomere IV not depressed; antennomere III two times longer than scape and 1/3 length of IV–XI, decreasing in length; antennomere XI about 1/3 length of III and with discrete apical projection.

Prothorax without tubercles or elevations; subparallel at sides. Prothorax ( Fig. 98 ) with fine and dense sexually dimorphic punctation except in a narrow longitudinal median line in posterior half and two longitudinal bands in semicircle, with coarse sparse punctures; long, erect whitish setae. Sexually dimorphic punctation with indentations deep and rounded ( Fig. 99 ), some with long setae ( Fig. 101 ); each indentation with four or five pores distributed entirely within indentations ( Fig. 100 ). Ventral region with long dense suberect whitish setae. Prosternal process with parallel sides and rounded apex. Mesosternum planar. Scutellum with short dense whitish setae. Surface of elytra with distinct coarse and confluent indentations; apices slightly truncate.

Sternite I 1.5 times longer than II; sternites II–IV subequal in length; sternite V with apical margin truncate.

Terminalia: Sternite VIII ( Fig. 51 ) with apical margin sinuous, lateral margin obliquely truncate; apophysis short, about half length of greatest length of sternite. Tergite VIII ( Fig. 52 ), apical margin rounded, with long setae. Ventral arc ( Fig. 53 ) with apophysis subequal to arms in length; dorsal arc ( Fig. 54 ) with apical margin rounded; tegmen about half length of median lobe; ring piece elongated. Median lobe ( Figs 58–60 ): dorsal lobe slightly shorter than ventral lobe, with apex rounded; ventral lobe with apices acuminate; basal apophysis more than two times longer than apical region. Internal sac with two sclerotized “L”-shaped pieces.

Female. Antennae reaching only to apices of elytra; ventral margin of antennomeres with long setae; outer margin of antennomeres slightly expanded and rounded to apex, more evident in antennomeres III–V; antennomeres III–VII with smooth and glabrous apices; antennomere XI about 1/3 length of III and subequal in length to X. Prothorax with coarse uniform punctures, moderately dense, with long erect whitish setae; prosternal process with apical margin truncate. Sternite V with apical margin truncate.

Terminalia: Sternite VIII ( Fig. 102 ) about 2.5 times wider than long; sternal apophysis two times longer than longest length of sternite; lateral margin with long dense setae in region between the brush of setae and the apophysis, with row of moderately dense setae with different lengths and tapered apices. Ovipositor ( Figs 62, 63 ) with basal region narrowed at sides; vulva narrowed; spermathecal gland shorter than spermatheca.

Measurements (mm). male/female n= 2/4. Total length 7.3–8.1/6.6–9.2; prothorax length 1.3–1.4/1.3–1.9; greatest prothorax width 1.3–1.5/1.2–1.7; elytral length 4.3–5.2/4.5–6.2; humeral width 1.6–2/1.6–2.3.

Type material. Gounelle (1911) described Trachelissa rugosipennis based on two females from Jataí, Goiás, Brazil. These two syntypes ( Figs 133, 134 ) were studied by Dr. Marcela L. Monné in the MNHN collection and, in order to promote nomenclatural stability, a lectotype and paralectotype are designated for the name Trachelissa rugosipennis ( Gounelle, 1911) .

Lectotype: 1 female ( Figure 133 ) (present designation): “Museum Paris / 1915 / E. Gounelle” “ Brésil / Ét. de Goyaz / Jatahy / Pujol 12-97 1 -98” “ LECTOTYPE ” “ Trachelia rugosipennis / goun.” ( MNHN). Paralectotype: 1 female ( Figure 134 ) (present designation): “Museum Paris / 1915 / E. Gounelle” Brésil / Ét. de Goyaz / Jatahy / Pujol 12-97 1 -98” “ PARALECTOTYPE ” ( MNHN).

Comments. Trachelissa rugosipennis differs from other species of Trachelissa in having the antennae, in males, with antennomeres III–V filiform and VI–XI expanded and serrate, more evident in the apical antennomeres, and antennomeres IV–XI gradually decreasing in length to the apex; antennomere XI with a small apical projection; the prothorax without tubercles; and the body covered by long whitish setae. Among the species whose terminalia were examined, only T. rugosipennis has the vulva narrowed and the basal region of the ovipositor narrowed at the sides. The shape of the tegmen is similar to T. pustulata .

Geographical distribution. This species occurs in Brazil (Goiás, Bahia) ( Monné, M.A., 2005). New state records from Minas Gerais and Espírito Santo are added (Figs 157,159).
