Chrysina arellanoi new species (Coleoptera: Scarabaeidae: Rutelinae) is described from the southern-most part of the Sierra Madre del Sur in Oaxaca, Mexico.Resumen. Se describe la especie nueva Chrysina arellanoi (Coleoptera: Scarabaeidae: Rutelinae) de la parte masmeridional de la Sierra Madre del Sur en Oaxaca, México.IntroductionCurrently the genus Chrysina Kirby (Coleoptera: Scarabaeidae: Rutelinae) is composed of 107 de-scribed species (Monzón and García 2011, Curoe 2011). The genus is distributed from the southwesternUnited States of America (specifically Arizona, New Mexico and Texas) through Mexico, Central Americato Colombia and Ecuador (Morón 1990). Recent collecting in some isolated mountains in Mexico byHector Arellano has provided specimens of several undescribed species. One of these species from theSierra Madre del Sur in Oaxaca, México, is described here as new. This species belongs in the  adelaidagroup (sensu Morón 1990, modified by Hawks 2001), which is now composed of 16 species. All the speciesin this group except C. centralis (Morón) and C. pehlkei (Ohaus) are known to occur in Mexico.Chrysina arellanoi Monzón, new species(Figures 1-11)Type material.

Holotype male. Length 24.0 mm; width at elytral humeri 11.0 mm; maximum width(middle of elytra) 12.5 mm. Color of dorsum shiny yellowish green; anterior half of clypeus pinkishbrown with metallic reddish gold on anterior margin, ocular canthi yellowish green, antennal segmentsbrown with scape dorsum yellowish green; pronotal margins iridescent yellowish green; scutellum withlateral margins yellowish green; elytra with external margins iridescent yellowish green, humeri andapical umbone greenish gold; pygidium green with lateral margins golden green. Color of venter yellow-ish green with golden and reddish iridescence and reflections. Legs with tibia reddish brown, coxae,trochanter and ventral surfaces metallic greenish gold; mesometasternal protrusion greenish gold.

Males length 23.0 to 24.0 mm; width at elytral humeri 11.0 to 12.0 mm; maximum width(middle of elytra) 12.0 to 13.0 mm. Females length 22.5 to 27.0 mm; width at elytral humeri 11.0 to 14.0mm; maximum width (middle of elytra) 12.0 to 15.5 mm. One male specimen represents a purplish brownform (Fig. 3) and five female specimens represent a reddish brown form (Fig. 4).Etymology. It is my pleasure to name this species for my friend and great insect collector HectorArellano, who is doing a great job of exploring the entomofauna of Mexico.Diagnosis. Chrysina arellanoi is a green species in the adelaida group (sensu Morón 1990, modified byHawks 2001). Along with C. citlaltepetlamayatli (Blackaller-Bages and Delgado), C. hawksi Monzón, C.lacordairei (Boucard), C. pehlkei (Ohaus) and C. purpurata (Morón), C. arellanoi is the only currentlydescribed green Chrysina species that has both the humeri and apical umbone metallic gold. In this groupof species C. purpurata has a completely reddish brown head and C. citlaltepetlamayatli a pronotumlaterally reddish pink. The species most similar to C. arellanoi are C. pehlkei and C. hawksi, but they caneasily be distinguished by the male genitalia.Distribution. Chrysina arellanoi is currently known to occur only in the Sierra Madre del Sur in theMexican state of Oaxaca. It has been collected around the towns of San Mateo Río Hondo and SanSebastián, which are roughly between 50 and 60 kilometers in a straight line north of Puerto Angel.AcknowledgmentsI am very grateful to Hector Arellano (Torreón, Mexico) for bringing to my attention this nice seriesof the new species of Chrysina. Enio B. Cano and Jack C. Schuster from the Universidad del Valle deGuatemala Collection of Arthropods contributed greatly with their comments and reviewing this manu-script. I would also like to thank Ingeniero Guillermo Ortíz Aldana (Ministerio de Agricultura y Ganaderíade Guatemala) for his help to import specimens for this research.Figures 9-11.
