Cyparium terminale Matthews, 1888

First Record for the State of Puebla ( Fig. 3a ). “ Mexico: Puebla , Honey , Chila de Juárez, San Marcos river, 20°17ʹ40.3ʹʹN, 98°13ʹ36.6ʹʹW, 1500 m, cloud forest, interception fly trap, 8 to 15-VIII-2019, J. D. Silva, R. Ramírez and J. Márquez cols.” (5♂, 3♀) .

Previous Records ( Fig. 3a ). Mexico: Estado de México (without precise locality), Hidalgo (Chapulhuacán: Arroyo Blanco, Tlanchinol: La Cabaña, Xochicoatlán: Malila river), Jalisco (without precise locality), Michoacán (Ocampo: Laguna Seca), Morelos (Tlayacapan: San José de los Laureles), Oaxaca (Santiago Jamiltepec: El Monroy, Santiago Yosondua: La Cascada-road to El Vergel, km 3 road Santo Domingo Tepuxtepec-Juquila Mixes) and Veracruz (Chocaman, Huatusco: km 30 road Fortín-Huatusco, Fortín de las Flores: Barranca Metlac, Sierra de Atoyac: Atoyaquillo, Xalapa); Guatemala and Panama ( Márquez 2007; Márquez and Asiain 2017; Navarrete-Heredia et al. 2002; Pedraza et al. 2010).

Biogeographic Comment. This species probably follows the distributional pattern and cenocron named Mountain Mesoamerican ( Halffter 2017; Morrone 2015), but its record in Panama is not completely concordant with this pattern or cenocron, which implies the expansion of taxa from the nucleus of Central America (north of Nicaragua, El Salvador, Honduras and Guatemala) toward the humid mountains of Mexico.

Color Variation. Márquez (2007) analyzed the color pattern in some specimens of C. terminale , where he found three predominant forms: one black, one reddish, and a third paler (possibly teneral). The specimens analyzed here correspond to the predominantly black form, with two reddish spots on each elytron, one near the humerus and the other towards the external posterior corner; the elytral epipleura and pronotal hypomeron are partially reddish, with legs bicolored and reddish at the anterior margin of some abdominal segments. The coloration of most of the studied specimens (7) is similar to that presented in fig. 1c of that work, except for one in which the elytra are completely black. The predominantly black specimens were collected in Morelos, Oaxaca and Veracruz. Later, Pedraza et al. (2010) and Márquez and Asiain (2017) recorded it in Hidalgo, but the color variation of these specimens has not yet been analyzed.
