Elytra from brownish-red or light brown to bicolor, black with quarter or half anterior red or brownish-red. Femora from black or red to bicolor, basal half brownish-orange or brownish-red and apical half from dark brownish to black. Tibiae from brownish-orange to brownish-yellow with darker base.

Antennal tubercles rugose and/or with shallow punctures. Upper eye lobes well-separated, distance between each upper eye lobe equal to three times the width of an upper lobe. Submentum from slightly to strongly excavated. Genae with short, decumbent and whitish hairs. Antennae 12–segmented, exceeding elytral apices, maximum at segment VII. Scape cylindrical and slightly expanded apically, with basal half rugose and/or with coarse and dense punctures, at apex with fine, shallow, and sparse punctures; pedicel with short and sparse pubescence; segment III with short and dense pubescence and fine and uniform punctures except at apex, which is smooth; segments IV–XII smooth, and covered by pubescence. Segments III–X subequal in length and 1/3 longer than scape; segment XI slightly shorter than X and 1/3 longer than XII, segment XII with apex curved.

Prothorax 1.4 times wider than long; surface alveolate ( Fig. 164 ). Antemedian tubercle strongly developed, sometimes as developed as postmedian tubercle; postmedian tubercle at right angle to axis of body or slightly curved to back. Sexually dimorphic punctation of the pronotum with indentations deep and rounded ( Fig. 165 ), denser and longer in lateral region; each indentation with number of cluster of pores varying, from one to six ( Fig. 166 ) distributed in all indentation, the pores may possess short and erect setae; between indentations are scattered points that may possess a short and erect seta, which is generally curved at apex ( Fig. 167 ). Sexually dimorphic punctation absent on transverse carina, median and postmedian elevations, anterior and posterior depression and on posterior region of the pronotum. Postmedian elevations may possess shallow and sparse punctures. Prosternum with sexually dimorphic punctation denser than on pronotum, some indentations asymmetric. Lateral regions of prosternal sulcus with short, dense and whitish hairs. Prosternal process subparallel, slightly narrowed in middle, smooth and elevated, at most ½ as broad as procoxal cavity. Mesosternal process, at most subequal as broad as mesocoxal cavity; with or without anterior projection; posterior margin truncate or slightly sinuous.

Scutellum approximately 1/5 length of elytra, smooth or with some fine and sparse punctures. Elytra gradually narrowed to apex, almost three times as long as prothorax; surface smooth or with some fine punctures in anterior region. Apices variable: curved, slightly sinuous or truncate.

Sternites I–V smooth or with fine and sparse punctures and with sparse, long, fine and whitish hairs; sternite V covered with dense and short pubescence; posterior margin truncate or slightly rounded. Sternite I 2.5 times as long as II; sternite II slightly longer than III, which is subequal to IV–V.

Terminalia: tergite VIII ( Fig. 173 ) with apical margin adorned with yellow hairs. Sternite VIII ( Fig. 172 ) transverse, apical margin slightly emarginate and with long hairs at sides and decreasing in length to middle region which is glabrous; sternal apophysis slightly short than longest length of sternite. Ventral arc ( Fig. 174 ) with short apophysis, about 1/10 as long as arms. Dorsal arc ( Fig. 175 ) with some sparse hairs. Tegmen ( Figs 176–178 ) ¼ shorter than median lobe; distal region divided into parameres, which are cylindrical-elongate and narrowed to apex; ring piece elongated, fused at apex, with short apical projection. Median lobe ( Figs 179–181 ): dorsal lobe slightly shorter than ventral lobe; both of them with rounded apex; basal apophysis 2/3 longer than apical region.

Variability. One specimen has the prosternal process as large as the procoxal cavity at its widest point. Sternite III–V gradually decreases in length.

Female. Last four antennomeres yellow. Antennae 12–segmented, reaching apical third or exceeding elytral apices at segment XI. Segment III slightly longer than scape and ¼ longer than IV; segments IV–V subequal in length; segments VI–X gradually decreasing in length, segment XI subequal to VII. Prothorax smooth. Postmedian tubercle curved to back. Disc of pronotum and lateral regions may possess long, erect, sparse and whitish hairs.

Terminalia: Tergite VIII ( Fig. 182 ) with apical margin slightly sinuous. Posterior region of sternite VIII ( Figs 168–171 ) two times wider than long; with a row of aciculate setae as long as conchoidal setae or shorter than them; conchoidal and petiolate setae with slits in dorsal region; sternal apophysis width about twice as long as longest length of sternite, apex about 1/3 longer than median region. Ovipositor ( Figs 183–184 ) with lateral lobes narrowed and divergent, margins with long hairs, inner margin straight and narrowed to apex; spermatheca “C” shaped, curved in apical region; spermathecal gland almost as long as spermatheca.

Variability. Antennomere III with a median region red, segments VI–VII can be black. Some specimens examined had shallow and fine punctures in the postmedian elevations.

Measurements (mm). female/male. n=36/57. Total length, 20.15±2.75/20.94±3.10; prothorax length, 4.77±0.61/5.00±0.72; greatest prothorax width, 6.71±0.98/7.00±1.10; elytral length, 13.44±1.80/13.46±2.29; humeral width, 6.89±0.99/7.25±1.85.

Type material. We examined the male neotype ( Fig. 157 ), from Goiás (Jataí), Brazil ( MNHN) .

Discussion. See other comments in Andraegoidus rufipes discussion. Hüdepohl (1985) acknowledged Trachyderes fabricii as a subspecies of A. rufipes and characterized it by having the head, pronotum and elytra black with anterior ¼ to half “red coral”. Andraegoidus rufipes fulvipennis was distinguished by having the anterior region of the pronotum very large and the antemedian tubercle strongly developed. Through examination of the neotype of Trachyderes fabricii ( Fig. 157 ), type-specimen of T. ebeninus ( Fig. 215 ), type-specimen photos from some of the synonyms of A. rufipes rufipes ( T. rufipes var. axillaris - Fig. 216 , T. rufipes var. brunnipennis - Fig. 217 , T. boisduvalii - Fig. 218 ), the original description of T. fulvipennis and more than 500 specimens of A. rufipes rufipes , A. rufipes fabricii and A. rufipes fulvipennis , we determined that the color pattern described by Hüdepohl (1985) as exclusive to the population of A. rufipes fabricii is also found in A. rufipes fulvipennis populations and we recognize the presence of the antemedian, strongly developed tubercle in both populations. Based on this study we elevate A. fabricii to species level and propose the synonymy of A. fabricii and T. fulvipennis .

Geographical distribution. The species is reported to Brazil (Mato Grosso, Goiás, Ceará to Bahia ), Bolivia ( Wappes et al., 2006). New states records from Brazil are added: Mato Grosso do Sul, Maranhão and São Paulo ( Fig. 228 ) .

Host plants. According to Monné (2001) the following host plants were cited for A. fabricii : Anacardium occidentalis L. ( Anacardiaceae ), Cassia leptophylla Vogel , Delonix regia (Bojer ex Hook.) Raf (Caesalpiniaceae) and Morus spp. (Moraceae) .
