Cyclocephala berti Delgado, 1992

Material Examined. Two males and five females labeled: “ MÉXICO: Veracruz, Zongolica, La Quinta, Amatitla. 29-30-V-2011. Luz mercurial. Bosque mesófilo de montaña. Alt. 1250 m, E. Mora, L. Delgado y L. Lara cols”. One female with same data, except 31-VI-2011. One male with same data, except 31-VII-2011. The specimens are deposited in the following collections: University of Nebraska State Museum (Nebraska, USA) 1 ♂ 1♀; Instituto de Ecología, A. C. (Xalapa, México) 2♀; L. Delgado Collection (Mexico City) 1 ♂ 1♀; and E. Mora-Aguilar Collection (Xalapa, México) 1 ♂ 2♀.

This species was described based on only one male specimen from the H. & A. Howden collection (now in Canadian Museum of Nature, Ottawa, Canada). The specimen was collected in the Los Tuxtlas region on the southeastern slope of the Volcán de San Martín, Veracruz, Mexico. Recently, nine specimens were collected at the Sierra de Zongolica, Veracruz. Male specimens agree with the description of C. berti, except for their larger size (length 13.7–16.8 mm, width across the humeri 6.5–7.3 mm), head completely covered with long and erect setae, and each elytron with 3 or 4 diffuse spots. Female specimens collected are similar to males except in the dimorphic characters, and are different from other species of Cyclocephala.

Description of the previously unknown female of C. berti is as follows: Total length 13.1–14.8 mm, width across the humeri 6.2–6.7 mm. Similar to male except in the following respects: Head and pronotum glabrous. Each elytron with 3–4 small, fuscous spots. Elytra and scutellum glabrous, except for the apex and posterior lateral third of elytra with small, sparse setae. Epipleuron expanded at level of metacoxa to abdominal sternites 2–3, with small, rounded, obtuse tooth between abdominal sternites 2–3. Pygidium almost flat, glabrous, except with small, erect setae on the base. Protibiae with basal tooth normal, teeth equidistant. Protarsus not enlarged, claws simple. Metatarsi slightly longer than metatibia.
