Approximately 4,000 species are reported in the subfamily Cetoniinae ( Coleoptera : Scarabaeidae ), which possess high levels of endemism within the various biogeographic regions. In the Neotropical region, 44 genera are distributed among four tribes ( Cetoniini , Cremastocheilini, Goliathini, and Gymnetini ) ( Krikken 1984). In Brazil, 47 species in 15 genera have been reported in the tribes Cetoniini and Gymnetini , as well as various subspecies ( Krajcik 1998; Morón 2004).

Larvae of Cetoniinae are found feeding on various substrates in the various habitats in which they live, such as soil organic matter, feces, rotting wood, termite nests, and ant nests. cetoniine adults feed on the exudates of plants, flowers or ripe fruits, nectar or pollen, or even crops without causing considerable economic damage.

In Brazil, there have been few studies on Cetoniinae , including those describing the immature stages (Vanin and Costa 1984; Costa et al. 1988; Micó et al. 2000, 2001), review and description of adults (Ratcliffe and Deloya 1992; Ratcliffe and Micó 2001 ; Ratcliffe 2011, 2005), and species diversity (Gonçalves and Louzada 2005; Puker et al. 2012). The occurrence of cetoniine species in the midwestern region of Brazil is little known, therefore, the objective of the present work was to study the species occurring in a forest fragment area between the cerrado and pantanal ecosystems near Aquidauana, Mato Grosso do Sul, Brazil.

The study was conducted in a cerrado forest fragment of about 20 hectares, located between the cerrado and pantanal ecosystems in the district of Piraputanga in the Sierra Maracaju , about 30 km east of Aquidauana, Mato Grosso do Sul, Brazil. The elevation is 149 m, average temperature is 26°C, and annual precipitation ranges from 1,250 to 1,500 mm .

Cetoniine adults were captured using traps baited with sugarcane juice and ripe bananas. Each trap consisted of a 2-L plastic bottle with three lateral windows measuring 8 × 8 cm and located 18 cm above the base. Four traps were installed weekly from August 2010 to July 2011 and remained in the field for three days at which time the insects were collected. The traps were installed at an average height of 1.5 m above ground and spaced apart by approximately 50 m. Captured insects were stored in 70% alcohol, mounted, and labeled. Later, they were examined under a Zeiss Stemi 2000 stereomicroscope and photographed with a Canon EOS 2000 digital camera coupled to the stereomicroscope.

Specimens of some species collected were identified by comparison with specimens deposited in the Laboratory of Systematics and Biology of Coleoptera (LabCol) (Universidade Federal de Viçosa, Viçosa, Minas Gerais, Brazil) and by using the original descriptions as a basis for comparison. Specimens of Gymnetis holosericea flava (Weber, 1801) , Gymnetis pantherina meleagris (Burmeister, 1842) , Gymnetis rufilatris (Illiger, 1800) , and Marmarina maculosa (Olivier, 1789) were identified by Dr. Miguel Angel Morón (Instituto de Ecología, A. C. (IEXA), Xalapa, Veracruz, Mexico). Voucher specimens are deposited in the entomology collections of the Universidade Estadual de Mato Grosso do Sul (Aquidauana), LabCol, and IEXA.

A total of 68 specimens were captured, representing nine species, one in the tribe Cetoniini and eight in the tribe Gymnetini . The species collected were Euphoria lurida (F., 1775), G. holosericea flava , G. pantherina meleagris , Gymnetis bajula vandepolli Olivier, 1789 , Gymnetis hebraica (Drapiez, 1820) , G. rufilatris , Hoplopyga boliviensis ( Moser, 1918) , Hoplopyga liturata (Olivier, 1789) and M. maculosa . These cetoniine species are new state records for Mato Grosso do Sul, however, the occurrence of some species at other locations is reported in the literature. The greatest abundance and species richness was found in March.

The cetoniinae fauna in the cerrado and pantanal ecosystem near Aquidauana is apparently exceptionally rich. Neita et al. (2006) obtained five species of Gymnetis Macleay in the lowland tropical rainforest in Chocó, Colombia, also when using traps baited with fruits. Gonçalves and Louzada (2005) captured five cetoniine species in a fragment of the Atlantic Forest in Lavras, Minas Gerais, Brazil.

Three adults of E. lurida ( Fig. 1 ) were captured, one in November and two in December. Adults of E. lurida have been reported in several locations of Brazil, with information on their association with plants ( Orozco 2012). According to Gallo et al. (2002), E. lurida consumes nectarine (leaves, flowers, and fruit), peach (leaves, flowers, and fruit), rose (flower), and grape (ripening fruit). In a three-year study, Garcia et al. (1993) sampled adults of E. lurida in a citrus orchard. The third instar was described by Micó et al. (2000) from larvae collected in Rio Claro, São Paulo, Brazil.

Nine adults of G. holosericea flava ( Fig. 2 ) were collected, one in December 2010, two in February, five in March, and one in April 2011. The traps yielded six adults of G. pantherina meleagris ( Fig. 3 ), three in November 2010 and three in February 2011. Two adults of G. bajula vandepolli ( Fig. 4 ) were obtained, one in March and the other in May 2011. A total of 21 adults of G. hebraica ( Fig. 5 ) were taken, four in October, two in December, four in January, two in February, seven in March, and two in May. Eight adults of G. rufilatris ( Fig. 6 ) were captured, one in September, two each in October and January, and three in May.

Eight adults of H. boliviensis ( Fig. 7 ) were taken, three in October, three in February, and two in April. In March 2011, six specimens of H. liturata ( Fig. 8 ) were captured. Five adults of M. maculosa ( Fig. 9 ) were collected, two in January and three in March.

Gymnetis bajula vandepolli (as Gymnetis vandepolli ), Hoplopyga liturata and Marmarina maculosa were found in Colombia by Neita et al. (2006) and Suárez-G. and Amat-García (2007). Solís (2004) recorded the occurrence of M. maculosa and H. liturata in Costa Rica.

Marmarina maculosa adults in Aquidauana are yellowish brown with irregular black spots. However, when studying this group of insects in Costa Rica, Solís (2004) reported that the predominant color of M. maculosa is opaque yellowish brown, with irregular black spots.

Hoplopyga boliviensis was previously known only from Bolivia ( Moser 1918; Ratcliffe 2004). Hoplopyga liturata is widely distributed throughout the Americas, being previously recorded in Mexico, Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Trinidad, Colombia, Venezuela, British Guiana, Ecuador, Brazil, and Argentina ( Solís 2004).
