ZooKeys 513: 105–121. doi: 10.3897/zookeys.513.9935 Abstract Four new species of Cymatodera are described from Mexico: C. tortuosa Burke & Rifkind, sp. n. from Hi- dalgo and Tamaulipas; C. ortegae Burke, sp. n. from Colima, Jalisco and Michoacan; C. gerstmeieri Burke & Rifkind, sp. n. from Chiapas; and C. mixteca Burke & Rifkind, sp. n. from Puebla and Guerrero. Male genitalia and other characters of taxonomic value are illustrated. Keywords Cleridae, Cymatodera, Mexico, brachyptery, Chiapas, Nevado de Jalisco, Sierra de Manantlan, Tehuacan Introduction As part of an ongoing effort to catalog the diversity of Mexican Cleridae, the present work describes four new species of Cymatodera Gray from the central and southern states of Mexico. As previously discussed (Rifkind 2014, 2015), the diversity of the clerid genus Cymatodera in Mexico is extensive, but our knowledge of the group re- mains rudimentary. Many dozens of species await description and many more are likely to be discovered, particularly in areas distant from paved roads. Recent descrip- tions of species belonging to this genus include many endemics (Burke 2013; Burke and Zolnerowich 2014; Rifkind et al. 2010; Rifkind 2014, 2015), and here again, it is quite likely that the tally will increase as collecting efforts reach further into habitats Copyright Alan F.

Burke et al. / ZooKeys 513: 105–121 (2015) such as relictual cloud forest and isolated mountain ranges that are known centers of endemism. Much attention has been focused on the rapid destruction or degradation of natural habitat in Mexico and other parts of Latin America, and the insufficiency of current resources dedicated to cataloguing disappearing biodiversity (Blackman et al. 2014; Armesto et al. 2007; Santibañez and Santibañez 2007; Trejo and Dirzo 2000). One positive trend is a recent increase in the number of trained taxonomists from these countries. Several workers in Mexico, for example, have undertaken faunistic and systematic studies of Cleridae with the result that the pace of description there is now higher than it has been in nearly a century (Burke 2013; Burke and Zolnerowich 2014; Rifkind et al. 2010, Toledo-Hernández et al. 2015). Should this trend continue, there may be more hope than previously thought for the assessment and conservation of critically threatened habitats in Mexico. Material and methods Genitalia extraction and dissection procedures are similar to those outlined by Ekis (1977). Most of the morphological terminology used follows the works of Ekis (1977), Rifkind (1996) and Opitz (2010). Morphology of the male genitalia and pygidia are considered of primary importance as characters for the determination of new species in this descriptive work. Specimens were observed using a Leica MZ 7.5 stereomicro- scope. Images were taken and measured using a Leica DFC 500 digital camera, and stacked using the software Zerene Stacker V. 1.04. The following abbreviations are used in the description of the holotypes: TL = Total body length, HW = Maximum head width, HL = Head length, PW = Maximum pro- notal width, PL = Pronotal length, EW = Maximum elytral width, EL = Elytral length.

The new species can be separated from congeners by its unique combination of body form, antennal shape, size, color, and elytral fascia pat- tern. Cymatodera tortuosa superficially resembles a number of species that share a simi- lar pattern of fuscous and testaceous elytral banding, such as C. balteata LeConte, C. sirpata Horn, C. undulata (Say), and C. wolcotti Barr. Cymatodera tortuosa, however, can be readily differentiated from those species based on clear differences in the male and female pygidium as well as discontinuity in geographic distribution. Specifically, the new species has the male pygidium distinctly modified (Fig. 11) compared to simi- lar species; the female pygidium is moderately, V-shaped emarginate (Fig. 16), rather than broadly rounded posteriorly, as observed in similar species. As no specimens are known outside of central Mexico, it is possible that this new species is restricted to that region, whereas those listed previously are distributed for the most part in the south and southwestern United States, with only C. balteata ranging into the Mexican bor- der states of Nuevo Leon and Tamaulipas. Description. Holotype male. Form elongate, slender; metathoracic wings present and fully developed. TL = 11.9 mm. Color: Head, pronotum and thorax piceous; elytra slightly lighter; antennae and mouthparts brunneous; legs testaceous; abdomen brunneous mesally, becoming pale testaceous laterally. Elytra with a pattern of testa- ceous markings and maculae as follows: the anterior 1/2 with a roughly X-shaped marking; each elytron at posterior 1/4 with a large, irregularly bordered, ovate macula narrowly separated at the elytral suture (Fig. 1). Head: HL = 2.15 mm, HW = 1.95 mm. Measured across eyes wider than prono- tum; surface smooth, moderately shiny, moderately, finely punctate; frons bi-impressed; sparsely clothed with short, very fine, recumbent setae, more profusely vested behind the eyes with longer setae; eyes moderately small, subsinuate, taller than wide, moderately emarginate in front, moderately protuberant laterally, separated by approximately 2.5 eye-widths. Antennae slender; loosely composed; extending beyond posterior margin of elytra; third antennomere about two times the length of second antennomere, fourth antennomere slightly longer than third antennomere; antennomeres 5–10 subequal in length; antennomeres 4–10 weakly serrate, serration very gradually increasing distally; last antennomere flattened apically, as long as tenth antennomere (Fig. 6). Thorax: PL = 2.75 mm,
