Six new species of Cymatodera from Mexico and Central America and the retention of Cymatodera obliquefasciata as a valid name (Cleridae, Tillinae).

Six new Cymatodera speciesfrom the Mexican states of Jalisco and Chiapas, and the Central American countries of El Salvador, Honduras, Costa Rica and Panamá are described: Cymatodera rosalinae sp. n., Cymatodera capax sp. n., Cymatodera sinuosa sp. n., Cymatodera vittata sp. n., Cymatodera rubida sp. n. and Cymatodera limatula sp. n. Justification for retaining Cymatodera obliquefasciata within Cymatodera instead of transferring it to Bogcia is provided. Male genitalia and other characters of taxonomic value are illustrated.

Introduction

The subfamily Tillinae Leach, 1835 has a worldwide distribution with 543 described species classified in 67 genera (Opitz 2010). The fauna is well represented in the North American temperate and subtemperate zones, the Neotropics, and the Paleotropic region of Africa, with an important concentration of genera and species in Madagascar (Opitz 2010). In the New World, the subfamily comprises the following genera: Barr, 1952, Rifkind, 1996, Barr, 1978, Van Dyke, 1938, Wolcott, 1911, Latreille, 1825, Gray, 1832, Barr, 1962, Wolcott and Chapin, 1918, Spinola, 1841 and Chapin, 1945. The Tillinae is a taxonomically complex group. Polymorphism is frequently encountered, the boundaries between both genera and species are rather difficult to establish, and it is common to observe species that appear to bridge the gap between generic taxa.

Barr (1948, 1952a, 1952b, 1972, 1978) and Rifkind (1993, 1995, 1996) are responsible for most of the recent descriptions and classificatory work treating the Tillinae of Mexico and Central America with a focus mainly on the fauna of northern mainland Mexico and Baja California. Despite some progress, most of the central and southern portion of Mexico has been poorly surveyed. Furthermore, our understanding of the Central American Tillinae fauna is even more limited, and our taxonomic knowledge of this geographical region has been scarcely added to in almost a century.

is the most speciose Tillinae genus in the New World, with a distribution that extends from southern Canada to Colombia and Venezuela (Opitz 2010). The highest diversity of described species is found in the southwest portion of the United States and the north of Mexico (Barr, personal communication). is well represented in Mexico (Rifkind 1993). Vaurie (1952) noted the presence of 37 species inhabiting the country, although the records she presented were mostly limited to north-central Mexico. At present, 20 species have been described from Central America (Barr, unpublished checklist).

The genus PageBreak was erected by Barr (1978) and is represented by two species, Barr and Barr, both restricted to the western portion of Mexico. Members of this group show strong similarities to ; however, theycan be reliably separated based on the structure of the protarsal unguis. The position of the tarsal claw is in close approximation with the denticle in (Fig. 22), rather than conspicuously separated as in (Fig. 23). Barr (unpublished checklist) included Schaeffer within . This placement was based on the strongly serrate condition of the antennae (Fig. 16). Nevertheless, I have found that this trait is not reliable for distinguishing from . The antenna of the latter is highly variable, and does not represent a character that marks a clear discontinuity in the group. Consequently, it is possible to encounter antennal forms that range from filiform (Fig. 18), as in LeConte, or moderately serrate (Fig. 19), such as Schaeffer, to strongly serrate (Fig. 15), as observed in the new species, , described below. Therefore, should be retained as based on the ungual structure of the protarsus.

This work is intended to be a small contribution towards a better understanding of the fauna of Mexico and Central America, and to shed some light on the complex relationships found in this group.

Methods

The methods used for genitalia extraction and dissection are similar to those described by Ekis (1977). Terminology used partially follows the work of Ekis (1977) and Rifkind (1996). I considered differences in the aedeagi as the primary evidence for determination of biological species (sensu Mayr 1963).

Specimens were observed using a Leica MZ APO stereomicroscope. All measurements were made using a stereomicroscope ocular micrometer and the software Leica Application Suite V. 3.4.0. Optic images were taken using a Leica DFC 500 digital camera. Scanning electron photographs were taken using a Hitachi 3500N variable pressure scanning electron microscope.

The following abbreviations are used in the description of the holotypes: TL= Total body length, HW= Maximum head width, HL= Head length, PW= Maximum pronotal width, PL= Pronotal length, EW= Maxium elytral width, EL= Elytral length.

Variation.

Female specimens differ from males in the following respects: antennal serration somewhat more evident (Fig. 10); elytral margins less parallel, rendering a somewhat more robust appearance; posterior margin of fifth visible ventrite broadly, shallowly,arcuately emarginate (Fig. 31); sixth visible ventrite subtriangular, lateral margins strongly oblique, almost confluent apically, posterior margin rather acuminate (Fig. 31); posterior margin of fifth tergite narrowly, moderately emarginate (Fig. 45); sixth tergite semicircular, lateral and posterior margins broadly rounded (Fig. 45); sixth tergite fully covering sixth visible ventrite. Pronotum and elytral ground color rather inconsistent in both sexes, ranging from testaceous to fuscous-brown. Midelytral fascia variably marked, almost imperceptible in some specimens. Some individuals possess an irregular, midelytral black band ranging in size from a complete fascia, to a pair of inconspicuous maculae on each side of elytra.

Differential diagnosis.

Distinguishable from congeners based on its size, antennal shape, midelytral marking, terminal abdominal segments and male genitalia. This species appears most similar to the allopatric species PageBreak. Color, form, elytral sculpturing, median pale fascia and serrate condition of antennae are characters shared by (Fig. 1) and (Fig. 7). This new species can be separated from the latter based on the following respects: has the antennomeres 2-4 slender, antennomeres 5-10 transversally robust in dorsal view and somewhat serrate (Fig. 9), due to sexual dimorphism, serrate condition of female specimens is somewhat more evident (Fig. 10), last antennomere internally sinuate, and humeral maculae absent. has the antennomeres 1-3 slender, antennomeres 4-10 transversally slender in dorsal view and boldly serrate (Fig. 16), and humeral maculae variably marked to absent. In addition, the moderately incised and arcuately emarginate posterior margin of the sixth visible ventrite in male specimens of (Fig. 24) is absent in males of (Fig. 30). The female of (Figs 31, 45) can be distinguished from females of (Fig. 37, 50) by the distinctive shape of its abdominal terminalia.

Distribution.

Known from the vicinity of the Chamela Biological Station, situated in the Chamela-Cuixmala region, on the western portion of Jalisco, Mexico.

Etymology.

I am very pleased to name this new species in honor of my mother, Rosalina Roco, a cornerstone in my life, and a person whose endless efforts have been of inspirational support during my professional career.

Separable from other PageBreak species based on its shape, elytral marking, unique terminal abdominal segments and male genitalia (Fig. 53). Due to the serrate condition of the antennae (Fig. 11), general size, form, color and midelytral fascia, (Fig. 2) appears closest to the Mexican (Fig. 8).The new species can be distinguished from the latter based on ungual differences of the protarsus. presents the claw of the protarsus conspicuously separated (Fig. 23) from the denticle, rather thanclosely approximated, as observed in (Fig. 22).

Known from two localities in the Guanacaste Province, Costa Rica: Playa Naranjo, adjacent to Santa Rosa, Guanacaste National Park; and Sector Las Pailas, Rincón de la Vieja National Park.

The specific epithet comes from the Latin word capax (= wide), a noun that makes allusion to the overall robust appearance of this new species.

Among these, is most similar to the Central American Gorham, 1882 and the Mexican Gorham, 1882. can be separated from the former as follows: anterior margin of elytra as wide as pronotum (wider in ); elytral margins conspicuously wide behind second half (somewhat subparallel in ); elytral apices (Fig. 3) broadly rounded and dehiscent (moderately rounded and feebly confluent in ); third antennomere (Fig. 12) as long as preceding antennomere (1.5 × the length of preceding antennomere in ). Furthermore, this new species is distinguishable from based on its unique pronotal and elytral sculpturing. has the pronotum finely, moderately punctate (coarsely, densely punctate, with punctations nearly confluent in ); pronotal disc conspicuously impressed in front of middle (flat in ); antescutelar impression strongly indicated (inconspicuously indicated in ); anterior half of elytral ground moderately punctate (densely punctate in ); interstices 2.0 × the width of punctation (less than the width of punctation in ). Likewise, the male of can be distinguished from males of other species sharing similar fasciae pattern and remaining congeners, by the unique combination of elongated, deeply incised, posteriorly elevated, and abruptly descended emargination on the sixth visible ventrite (Fig. 26).

The species is known from two localities: La Muralla National Park, situated in the department of Olancho, Honduras and El Boquerón National Park, in the Department of San Salvador, El Salvador.

The specific name comes from the Latin noun sinuosa (=sinuous), and refers to the winding character of the fasciae found on the elytral ground of this species.

One male with anterolateral carinae of sixth visible ventrite more strongly pronounced. One male with surface of sixth ventrite feebly convex. Two females with posterior margin of sixth tergite truncate.

Its distinct elytral ground color, slender form, shape of terminal abdominal segments and male genitalia will readily separate this species from congeners. appears especially similar to , a sympatric species described below. Differences in antennal shape (Figs 13, 14) serve to separate this new species from its closest congener. has the fourth antennomere conspicuously longer than preceding antennomere (antennomeres 3-4 about the same length in ); antennomeres 5-10 are somewhat longer and extend beyond basal sixth of elytral ground (antennomeres 5-10 are slightly shorter in and do not extend beyond basal sixth of elytral ground). Additionally, the distinctive metasternal sensory area found in the male of is poorly developed in males of (Figs 58, 59). Differences in terminalia (Figs 27, 28, 41, 42) and male genitalia (Figs 55, 56) also distinguish this new species from .

Known from three localities in Panamá: El Llano, Panamá Province; 4 km south of Gamboa, Colón Province; and 4 km south of El Valle, Coclé Province.

The specific epithet comes from the Latin noun vitta (=band), and refers to the posterior fascia on the elytral ground of this new species.

Conspicuous differences in terminal abdominal segments (Figs 27, 28, 41, 42) and male genitalia (Fig. 55, 56) also distinguish this new species from .

Known from five localities in Panamá: the Canal Zone, 5 km south of Gamboa; Fuerte Kobbe; the mountainous region of Cerro Azul; the surroundings of Palenque; and El Llano-Carti road, 12 km north of El Llano.

The specific epithet comes from the Latin noun rubida (=red), this adjective indicates the general reddish color of this new species.

Moreover, abdominal differences are as follows: fifth visible ventrite rugose, lateral margins oblique, posterior margin truncate (Fig. 36); sixth visible ventrite rugulose, semicircular, surface feebly convex, broader than long, lateral and posterior margins broadly rounded (Fig. 36); fifth tergite rugulose, lateral margins oblique, posterior margin truncate; sixth tergite rugulose, broader than long, surface inconspicuously convex, lateral and posterior margins strongly oblique, slightly acuminate posteriorly, almost semicircular. Posterior margin of sixth tergite extending slightly beyond sixth visible ventrite. One male paratype does not possess the irregular, small, black maculae located on the posterolateral area of pronotum.

The distinctive coloration and elytral markings of this species will serve to separate it from congeners. No other species in the group has the distinctive piceus fasciae on the pronotum and elytral ground, and the predominantly black color on the head (Figs 6, 60). In addition, shape of terminal abdominal segments (Figs 29, 36), strongly serrate condition of antennomeres 4-10, shape of last antennomere (Fig. 17), and male genitalia (Fig. 57) are characters that serve to separate from remaining species.

This species is known from three localities in the state of Chiapas, Mexico: El Aguacero, in the periphery of Tuxtla Gutierrez; El Chorreadero, 8 km northeast of Chiapa de Corzo; and on highway 190, 17 km west of Tuxtla Gutierrez.

The specific epithet comes from the Latin noun limatula (=distinctive), and makes allusion to the characteristic color pattern of this new species.
