Brachystethus sexmaculatus   HERRICH- SCHÄFFER, 1853:310, fig. 1010; STÅL, 1862:118 (syn.).

Type material of B. rubromaculatus   . Lectotype, here designated, labeled: a) Honduras/45123; b) “a”; c) Type; d) Dyson coll. (BMNH); paralectotype, here designated, labeled: a) Mexico; b) “b” (BMNH). Type locality: Honduras and Mexico.

Description. Dorsal surface black, withred spots of variable extension on pronotum, scutellum andcorium (figs. 2, 3). Headentirely black, with conspicuous wrinkles. Punctures sparse; semi-circular stripes little conspicuous, moderately punctured. Antennae black; fourth antennal segment medially swollen, with longitudinal sulcus. Second antennal segment about one and a half as long as first; third slightly longer than second; fourth almost twice as longas thirdand slightly shorter than fifth. Pronotum black, with a large, rounded, red spot medially; in some specimens, extended laterally over most part of disc, except on a narrow black stripe on anterior and anterolateral margins. Punctures black, minute, regularly distributed on the disk of pronotum; among them, sparser and larger punctures. Scutellum black, with a rounded, red spot, which occupies the center of median-apical region; in some specimens, it extends anteriorly and posteriorly, covering the apical 2/3 of scutellum. Surfaceof basalhalf sub-rugose, with large punctures regularly distributed. Apical half with fine punctures, moreconcentrated lateraland apically. Corium without callus, color pattern variable, usually black, with a large red spot on basal third and another on apical third, except along lateral margins. In some specimens, the corium is predominantly red, with black portion restricted to a thin lateral stripe and one small spot near to apex of radial vein. Ventral surface of thorax dark reddish-brown to black, with a red spot near to outer margin of metaepimerum; punctures fine, concolor. Ostiolar rugae extending by 2/3 of distance between the inner margin of ostiolum and lateral margin of metapleura. Metasternum, in profile, strongly elevated anteriorly. Legs dark reddish-castaneous to black. Connexival segments entirely black; punctures fine, moderate and regularly distributed. Venter black to dark reddish-castaneous, with 1+1 oblong red spots of variable length, generally extendingfrom anterior margin of fourth sternite onto a little bit beyond the anterior margin of seventh. In some specimens, the spots can become coalescent, making the abdomen almost totally red, only with a lateral black stripe. Punctures fine, very sparse, if present restricted to medial area. Spiracles black.

Male genitalia. Pygophore trapezoidal, wider apically. Lobes of dorsal rim conspicuous, slightly projected posterad, rounded at apex. Genital cup processes moderately visible dorsally (figs. 14, 24). Parameres with wide apex, anterolaterally directed, a little wider than half length of tenth segment (fig. 44). Ventral rim broadly Vshaped (fig. 34). Phallus as described for the genus (figs. 53-55).

Female genitalia. Gonocoxites 8 with posterior borders convex andsutural borders parallel and contiguous, except at apex (fig. 56). Gonocoxites 9 more than three times wider across arms apices than long medially; anterior border broadly U-shaped. Arms of gonocoxites 9 with length equal to 1/4 of plate width across apices of arms. Thickening of vaginal intima digitiform. Ductusreceptaculi thin, about one and a half longer before than after vesicular area. Capsula seminalis globose. Annular crests convergent (figs. 65, 66).
