A comparative study of Coleoptera Scarabaeoidea in the community of Calmeca, Tepexco, Puebla, Mexico is presented. Samples of beetles were taken from November 2013 to November 2014 in a place with induced pasture land with neighboring crops (SP) and a site representative of deciduous forest with secondary vegetation (SC). By mean of necrotraps, rotten fruit traps and hand collecting, 945 specimens were obtained, representing 28 species in six families of Scarabaeoidea. The SP had the highest species richness with 27 species; the most abundant species was E. intermedius (30.19%) with 257 specimens, followed by D. gazella (14.33%) with 122 specimens. In the SC the most abundant species were C. (C.) humectus (20.21%) and C. (C.) pluto (20.21%) each with 19 specimens collected. No significant differences between the two sampling sites (p = 0.111) were found. The Calmeca beetle community was grouped in eight feeding guilds. At both sites most recorded species belong to the coprophagous guild (SP 37% & SC 53%), the necrophagous guild (SP 14.8% & SC 26.6%) and the phytophagous guild (SP 18% & SC 13%). The SP had a higher functional richness with eight guilds, compared with the SC with four guilds; in the SC no species of predator, antophilous, and rhizophagus guilds were recorded.

Comparative analysis of beetles of the family Melolonthidae established in rancho Canaletas, Paso del Macho, in the centre of the state of Veracruz, México is presented. Data were obtained from January to December 2008, in evergreen rain forest (SP) and plantations of sugar cane (ZA), located at 500 m altitude. By mean of light traps, rotten fruit traps and hand collecting, 557 specimens were obtained, representing 5 subfamilies, 13 genera and 42 species. Of all the species collected, 10 had exclusive distribution in SP and 16 were distributed only in ZA. The agricultural area showed higher richness (32) and abundance (422) than the evergreen forest zone (richness 26 and abundance 135). Phyllophaga temora, P. pubicollis, Paranomala inconstans, and Phalangogonia jamesonae are recorded by first time for the state of Veracruz. By mean of parsimony analysis of endemicity the close affinity between the fauna of Melolonthidae from Rancho Canaletas, Los Tuxtlas, Veracruz and Boca de Chajul, Chiapas is evidenced.

In this work a comparative analysis of the scarab beetles of Cuetzalan del Progreso, Puebla, México is presented. Data were obtained from March 1998 to March 1999 in tropical rain forest, induced pasture land and secondary vegetation, between 400-1000 m above sea level. Records of 7 subfamilies, 18 subtribus, 34 genera and 63 species are presented. The greatest specific diversity corresponds to Dynastinae (21 spp), Melolonthinae (13 spp), Scarabaeidae (13 spp) and Passalinae (8 spp). The 50% of the species are concentrated in the genera: Phyllophaga (9 spp), Cyclocephala (9 spp), Onthophagus (5 spp), Ataenius (3 spp), Passalus (3 spp) and Anomala (2 spp). We present a parsimony analysis of endemicity in order to know the relationships between the fauna of Cuetzalan and other Mexican localities. The fauna of Cuetzalan de Progreso is closely related to the fauna of the humid mountains of the northeast of Hidalgo. A key to the taxa found in Cuetzalan del Progreso is included.

A comparative analysis of beetles of the family Scarabaeidae (sensu stricto) from "Rancho Canaletas", Paso del Macho, in central Veracruz State, Mexico, is presented. Data were obtained from january to december in 2008 in an evergreen tropical forest (SP) and a cattle grazing plot (PT), at an altitude of 500 m above sea level. Copro-necrophagous beetles were captured with traps baited with human feces or squid, and by hand in cow dung, obtaining 560 individuals from 3 families, 11 genera and 18 species. The species Canthidium céntrale (Boucomont), Canthon euryscelis (Bates), Deltochilum pseudoparile (Paulian), Deltochilum scabriusculum (Bates), Eurysternus angustulus (Harold) and Sulcophanaeus chryseicollis (Harold) are exclusive to SP, and Coprophanaeus pluto (Harold) y Omorgus rubricans (Robinson) are exclusive to PT. Species richness, diversity and abundance is higher in SP than PT; the beetle fauna in this locality can be associated with the fauna from Pipiapan, Boca del Chajul and Los Tuxtlas, from the states of Veracruz and Chiapas.
