Cymatodera bogcioides Burke

Holotype. Medium-sized, rather robust, posterior wings fully developed, TL = 12.75 mm. Color: Head, pronotum, prosternum, mesosternum and metasternum ferruginous, remainder of body uniformly brown. Each elytron with two pairs of dark maculae, the first pair dark brown, located on the humeral angles, the second pair on the median region of the elytral ground, this pair extends from the second to the fifth stria (Fig. 1). Head: HL = 1.2 mm, HW = 2.2 mm. Measured across eyes wider than pronotum; finely, moderately punctate, vested with semirecumbent setae; surface slightly rugose; frons moderately bi-impressed; eyes large, feebly emarginate in front, rounded, bulging laterally, separated by approximately 1.2 eye-widths. Antennae loosely composed, extending slightly beyond elytral base; third antennomere 2.0× longer than second antennomere, antennomeres 4–10 subequal in length, longer than broad, strongly serrate; blunt at posterolateral portion; last antennomere 2.1× longer than tenth antennomere (Fig. 6). Thorax: PL = 2.75 mm, PW = 1.85 mm. Pronotum widest at middle; sides constricted subapically, more strongly constricted behind middle; disc flat, not constricted in front of middle; moderately vested with short, semirecumbent setae intermixed with less numerous, semierect setae; surface rather rugose, rugosity becoming more apparent on sides; moderately punctate, punctation somewhat shallow and less numerous on disk; subbasal tumescence feebly indicated. Prosternum smooth, very feebly puncticulate, slightly rugose. Mesosternum moderately, coarsely punctate; scarcely vested with fine, recumbent setae. Metasternum convex; moderately, finely punctate; mesal area with a longitudinal sulcus; covered with fine, recumbent setae. Legs: Clothed with semirecumbent, semierect, and erect setae of various sizes; femora moderately, shallowly puncticulate, rugulose; tibia moderately, shallowly punctate, rugose; fourth protarsomere with pulvillus medially incised, incision does not extend beyond apical fourth. Elytra: EL = 7.7 mm, EW = 3.5 mm; broader than pronotum; humeri indicated, rounded; sides subparallel; widest behind middle; disc flattened above; surface shiny, slightly rugose; apices subquadrate; moderately dehiscent; elytral declivity moderately steep; clothed with short, semierect setae intermixed with less numerous, long, semierect and erect setae; sculpture consisting of coarse punctations arranged in regular striae that gradually become smaller and shallower behind posterior 1/4, punctations not reaching elytral apex; interstices at elytral base about 2.5× width of punctation. Abdomen: Ventrites 1–5 rugose; moderately, finely punctate; clothed with long, fine, recumbent setae. First ventrite convex; subquadrate; posterior margin conspicuously elevated with a transverse carina originating next to posterolateral angles producing a broad, deep, arcuate emargination (Fig. 30). Second visible ventrite somewhat convex; subquadrate; posterior margin slightly elevated with a longitudinal carina producing a moderately broad, rather deep, arcuate emargination. Ventrites 3-4 convex; subquadrate; posterior margin truncate. Fifth visible ventrite convex; lateral margins oblique; posterior margin broadly, deeply emarginate, emargination extending to posterior third of its length; hind angles rounded (Fig. 16). Sixth ventrite subtriangular; surface rugulose; feebly convex; broader than long; lateral margins feebly arcuate, strongly oblique; posterolateral angles rounded; posterior margin broadly, very feebly, shallowly emarginate. Fifth tergite convex; surface rugulose; subquadrate; posterior margin very feebly, narrowly emarginate (Fig. 17). Sixth tergite feebly convex; semicircular; lateral and posterior margins broadly rounded. Sixth tergite extending beyond apical margin of sixth visible ventrite, fully covering sixth ventrite from dorsal view. Aedeagus: 1.95 mm long; ratio of length of paramere to whole tegmen 0.35: 1; tegmen partially covering phallus; parameres moderately developed, pointed at apex; phallobase wide; phallus with copulatory piece acuminate distally; phallic plate devoid of denticles, finely granulate on posterolateral area; phallobasic apodeme rather long, moderately robust distally; endophallic struts slender throughout length (Fig. 11). Females in the type series differ from males by having the first visible ventrite moderately longer than males, and ventrites 1–2 posteriorly truncate and lacking the moderately elevated transversal carina (Fig. 31). Other abdominal differences in the female are as follows: fifth visible ventrite rugulose; lateral margins oblique; posterior margin shallowly, moderately broadly emarginate. Sixth visible ventrite semicircular; rugulose; feebly convex; lateral and posterior margins broadly rounded (Fig. 26). Fifth tergite rugulose; subtriangular; lateral margins oblique; posterior margin shallowly, moderately broadly and triangularly emarginate. Sixth tergite subtriangular; rugulose; broader than long; surface inconspicuously convex; lateral and posterior margins strongly oblique, producing a rather continuous and semicircular margin. Sixth tergite extending beyond sixth visible ventrite.

The type series was collected in two localities close to each other in the western portion of the state of Jalisco, Mexico. The first locality is in Costa Careyes, in the Costalegre region, and the second locality is the UNAM Biological Research Station located in the Chamela-Cuitzmala natural reserve (Fig. 34).
