Differential diagnosis: The new species can be distinguished from congeners based on the large size, robust pronotum and elytra ( Fig. 3 View FIGURES 1 – 5 ), and the strongly serrate condition of the antennae ( Fig. 32), a combination of characters not found in other Cymatodera species. Cymatodera crassa also resembles members of Lecontella Wolcott and Dybas , but it can be differentiated from species of this genus if the elytral punctations are narrow, shallow and do not reach the elytral declivity, rather than coarse, deep, and extending to the elytral declivity, as observed in Lecontella species.

Description: Holotype male. Form elongate; cylindrical; elytra subparallel, robust; metathoracic wings present. Total length: 14.54 mm. Color: integument uniformly testaceous to brown, except head, mouthparts and pronotum darker, fuscous to almost black; median region of elytral ground with a pale transversal band, this band extends from elytral suture to epipleural fold ( Fig. 3 View FIGURES 1 – 5 ).

Head: HL = 2.64 mm, HW = 2.6 mm. Measured across eyes wider than pronotum; surface smooth, shiny, feebly punctate, punctuation shallow and small; frons not bi-impressed; clothed with short, fine, recumbent setae; eyes large, rounded, separated by approximately 1.25 eye-widths, bulging laterally. Antennae extending slightly beyond anterior margin of elytra; third antennomere about 3.5 × the size of second antennomere, antennomeres 3- 10 approximately same size, eleventh antennomere elongate, slightly depressed medially, approximately same size of ninth and tenth antennomeres combined; second antennomere cylindrical, third antennomere feebly serrate, antennomeres 4-10 strongly serrate ( Fig. 32).

Thorax: PL = 3.85 mm, PW = 2.26 mm. Pronotum elongate, widest at middle; sides constricted laterally, slightly more strongly constricted behind middle; disc flat, very feebly impressed in front of middle; subbasal tumescence feebly impressed; surface shiny, somewhat rugulose, feebly punctate, punctuation narrow and shallow; vested with short, pale, recumbent setae intermingled with few long, semi-erect, pale setae; vestiture more abundant laterally. Prosternum wider than long; surface shiny, feebly rugulose, glabrous. Mesoventrite subquadrate; surface coarsely rugose anteriorly, shiny posteriorly; punctate, punctations shallow and narrow; feebly vested with semirecumbent, long setae. Metaventrite strongly convex; surface rugulose; coarsely, shallowly punctate, punctuation narrow, moderately deep; vested with fine, pale, semirecumbent setae.

Legs: Femora shiny, finely, conspicuously punctate, punctuations shallow and narrow; clothed with long, pale, semierect setae. Tibiae shiny; vested with short, semirecumbent setae mixed with some scattered erect setae; coarsely punctate, punctuation broad and deep.

Elytra: EL = 9.8 mm, EW = 4.82 mm. Anterior margin arcuately emarginate; wider than widest portion of pronotum; sides feebly arcuate; widest on posterior 1/3; disc rather convex; apex rounded, dehiscent; elytral sculpturing arranged in regular striae; punctuation abundant, coarse and deep on first half of elytral disc, then gradually diminishing in size, depth and number, disappearing on posterior 1/4; punctations at elytral base coarse and deep; very finely, shallowly punctate at interstices; surface clothed with short, pale, fine, semirecumbent setae intermixed with few, scattered, long, pale, erect setae.

Abdomen: Ventrites 1–2 shiny; moderately, finely punctate; clothed with short, pale, fine, recumbent setae; each ventrite with a median, longitudinal, slightly elevated carina that do not reach the lateral margin of segment ( Fig. 29 View FIGURE 27 – 30 ). Ventrites 3-4 feebly convex; subquadrate; coarsely punctate, punctations more abundant on posterior 1/2; vestiture pale, recumbent. Fourth visible ventrite conspicuously vested on posterior 1/2. Fifth ventrite subtriangular; surface feebly rugose; shallowly, finely punctate; lateral margins oblique, somewhat arcuate; posterior margin broadly, deeply emarginate ( Fig. 9 View FIGURES 6 – 17 ). Sixth visible ventrite small, subtriangular; surface shiny; vested with some long, pale, recumbent setae; more conspicuously vested on posterior 1/3; lateral margins oblique; posterior margin broadly, shallowly, U-shaped emarginate ( Fig. 9 View FIGURES 6 – 17 ). Fifth tergite rugose; moderately deeply, Vshaped emarginate ( Fig. 10 View FIGURES 6 – 17 ). Sixth tergite subquadrate; slightly broader than long; surface very finely rugulose; vested with some semierect, pale setae; posterior 1/4 conspicuously vested with fine, recumbent, pale setae; lateral margins subparallel; posterior margin subtruncate, shallowly, widely notched; posterolateral angles rounded ( Fig. 10 View FIGURES 6 – 17 ). Posterolateral angles of sixth ventrite do not extend beyond posterior margin of sixth tergite.

Aedeagus: AL = 1.8 mm. Feebly sclerotized; ratio of length of paramere to whole tegmen 0.24: 1; tegmen partially covering phallus; parameres feebly developed, pointed at apex; phallobase narrow; phallus with copulatory piece tapered at apex; phallic plate devoid of denticles, very feebly granulate on lateral margins; phallobasic apodeme long, slender; endophallic struts slender throughout their length ( Fig. 24 View FIGURE 22 – 26 ).

Variation: Members of the type series present variation in length, ranging from 8.5 to 15.9 mm. Two females are slightly paler than remaining member of the type series. Other characters are constant.

Females: The eleventh antennomere of females in the type series is shorter than the same antennomere of males. In addition, females are somewhat more robust than males. Finally, the first visible ventrite of females lacks the longitudinal carina observed in males ( Fig. 29 View FIGURE 27 – 30 ), and the sixth abdominal segment is rounded posteriorly, with the lateral and posterior margins producing a semicircle ( Figs 17 View FIGURES 6 – 17 , 18 View FIGURE 18 – 21 ).

Distribution: The new species has been collected throughout the central and southern half of México and the Central American countries of Guatemala and Honduras ( Fig. 33 View FIGURE 33 ).

Etymology: The specific epithet crassa derives from the Latin word “crassus”, meaning thick or stout, an allusion to the robustness of this new species.
