“…Only L. fusca and L. suturalis (Blanchard) have been recorded as agricultural pests, mainly in the “Cerrado”, a Brazilian savannah biome. Liogenys fusca was found damaging corn and soybean in Mato Grosso do Sul, Mato Grosso, and Goiás States (Rodrigues et al 2008, Santos et al 2008, Costa et al 2009, Ávila et al 2014). Liogenys suturalis damages corn, wheat, and oats in Mato Grosso do Sul (Santos and Avila 2009).…”

“…The two former species are important pests of grain crops due to their rhizophagous habits (Santos et al 2008, Costa et al 2009, Santos and Ávila 2009). Less is known about the biology of all other Liogenys species, although some adults were found feeding on shrubs causing injury to some fruit trees, and they are attracted by lights at night (Gutiérrez 1951, Silva et al 1968, Frey 1969).…”

Liogenys Guérin-Méneville, 1831 is the major genus of Neotropical Diplotaxini, with 78 species distributed from Panama to southern Argentina and Chile, except for Ecuador. Due to the large numbers of both described and undescribed species, as well as its agricultural importance, mainly of those in Brazil, Liogenys was redefined and redescribed. Nine new species are described: L. cavifrons Cherman, sp. n., L. femella Cherman, sp. n., L. piauiensis Cherman, sp. n., L. rotundicollis Cherman, sp. n., L. pseudosanctaecrucis Cherman, sp. n., L. grossii Cherman, sp. n., L. pseudospiniventris Cherman, sp. n., L. sulcoventris Cherman, sp. n., and L. freyi Cherman, sp. n. All the new species are Brazilian, except for the last one, which is Argentinian. Twenty-three Brazilian species are redescribed and illustrated. Five new synonyms are proposed, and 19 lectotypes are designated. New geographical distribution records for 19 species are presented, as well as a key to New World Diplotaxini and Brazilian species of Liogenys.

The beetle, Anomala testaceipennis Blanchard (Coleoptera: Scarabaeidae), occurs in central-western Brazil where larvae feed on the roots of plants causing damage. This research aimed to study sexual dimorphism and mating behavior of A. testaceipennis . Adults of A. testaceipennis were collected with light traps in the experimental area of the State University of Mato Grosso do Sul, in Aquidauana. Laboratory experiments were performed to describe copulation behavior and adult morphology of males and females. In males the last abdominal segment has a pronounced constriction, which is absent in females, and the male’s last segment of the first pair of legs has a ventral projection, which is poorly developed in females. The mating activities of adults begin soon after sunset, when adults leave the soil and fly. When the male encounters a female, he touches her with antennae and tarsi. If accepted, the male climbs on the female and remains on her back, and soon after the copulation begins. When the female does not accept the male for mating, she moves rapidly and can roll on the ground, and by so removing the male. In the field, adults feed and mate on bloomed trees of Oiti, Licania tomentosa Benth (Malpighiales: Chrysobalanaceae) and Louro, Cordia glabrata Martius (Boraginaceae). In trees without inflorescences no adults of this species were found.

First report of Liogenys suturalis (Blanchard) (Coleoptera: Scarabaeidae: Melolonthinae) in Argentinian crops and the first report of damage on soybean

et al. 2021

Liogenys Guérin-Méneville is one of the most species rich genera in the Scarabaeidae family endemic to South America. Some species of this genus are important rootfeeding pests of maize, soybean, wheat and oat in their larval stage. Prior to the present study, all known reports of damage caused by any Liogenys species were from Brazil. Since 2006 in Argentina white grubs of the genus Liogenys (not previsouly identified to species level) have been recorded causing a decrease in soybean yields. This research confirms that the Argentinian species is L. suturalis (Blanchard), an important pest already recorded in Brazil but associated with yield losses of maize crops instead of soybean. Taxonomical and biological data observed in Argentinian populations are presented. This is the first record of L. suturalis damaging soybean and its first report in Argentinian crops. K E Y W O R D S Diplotaxini, root-feeders, scarab beetles, soil pest species, white grubs Premier signalement de Liogenys suturalis (Blanchard) (Coleoptera : Scarabaeidae : Melolonthinae) sur cultures en Argentine et premier signalement de ses dégâts sur soja Liogenys Guérin-Méneville est un des genres comportant la plus grande diversité d' espèces au sein de la famille des scarabéoïdes (Scarabaeoidea). Il est endémique à l'Amérique du Sud. Certaines espèces de ce genre sont, au stade larvaire, d'importants organismes nuisibles rhizophage du maïs, du soja, du blé et de l'avoine. Précédemment à cette étude, tous les signalements connus de dégâts causés par des espèces de Liogenys provenaient du Brésil. Depuis 2006, en Argentine, des vers blancs du genre Liogenys (qui n' ont pas été précédemment identifiés au niveau de l'espèce) ont été signalés, provoquant une baisse des rendements de soja. Cette étude confirme que l'espèce responsable de ces dégâts en Argentine est L. suturalis (Blanchard), un organisme nuisible important, déjà signalé au Brésil mais associé dans ce pays à des pertes de rendement des cultures de maïs plutôt que de soja. Les données taxonomiques et biologiques observées dans les populations argentines sont présentées ici. Il s'agit du premier signalement de L. suturalis causant des dégâts sur soja, et de son premier signalement sur cultures en Argentine.
