Abstract:ABSTRACT. Two nes spccics of Arhysosage Brethcs from Brazil (Rio Grande do Sul) and Argentina (Salta) (Hymenoptera, Apoidea, Panurginae). Two new species of Arhysosage are described: A. cactorum sp.n. from Rio Grande do Sul, Brazil and A. melanothricha sp.n. from Salta, Argentina. KEY WORDS. Hymenoptera, Apoidea, Panurginae, Arhysosage, new species Em 1958 publiquei um pequeno trabalho sobre Arhysosage Brethes, 1922 dando a conhecer sua posição sistemática entre os Panurginae e descrevendo duas espécies da … Show more
“…Morphological examination of the holotype of A. cactorum ( Figure 4B, D-F) and A. melanothricha ( Figures 6A-F) supports the status of A. melanothricha as a valid species, as initially proposed by Moure (1999) and subsequently by Moure et al (2007).…”

“…Arhysosage melanothricha is known from a single male holotype. As described by Moure (1999), A. melanothricha can be readily distinguished by its long dark pilosity on the head and mesoscutum, which contrasts with the yellow body ( Figure 6A-C). Arhysosage melanothricha is morphologically similar to A. atronulata, A. bifasciata and A. ochracea due to the presence of yellow bands on the metasomal terga ( Figure 6E), and the distal margin of male clypeus is slightly convex between the lateral corners ( Figure 1A).…”

“…According to Schlindwein (1995) and Schlindwein and Wittmann (1995), the reproductive biology of Arhysosage species is associated with cactus flowers, and this behaviour contributes *Email: kellisramos@yahoo.com.br significantly to pollination of these species. Males of Arhysosage cactorum Moure, 1999 were observed flying around flowers of Notatocactus, Gymnocalycium and Frailea in search of females; males initiate copulation inside the flowers and continue copulating in flight while females keep on foraging (Schlindwein 1995;Schlindwein & Wittmann 1995). In males, the long curved mandibles seem to be important in the mating behaviour, in that the male grabs the female's waist while mating in flowers (Schlindwein & Wittmann 1995;Engel 2000).…”

“…All species are strictly associated with the Chaco vegetation, except for A. cactorum, which is found in the Pampa. The genus was first revised by Moure (1958), and subsequently by Engel (2000), who reconstructed the phylogenetic relationships among species, and provided an identification key for six recognized taxa: Arhysosage atrolunata Engel, 2000;Arhysosage bifasciata (Friese, 1908); Arhysosage cactorum Moure, 1999; Arhysosage flava Moure, 1958;Arhysosage ochracea (Friese, 1908); Arhysosage zamicra Engel, 2000. More recently, the Catalogue of Neotropical Bees (Moure et al 2007) listed seven species in the genus, with the reinstatement of Arhysosage melanothricha Moure, 1999, previously considered a junior synonym of A. cactorum by Engel (2000).…”
A new species, Arhysosage biguttulata sp. nov., is described and illustrated based on adult specimens collected in the Chaco region of Mato Grosso do Sul State, Brazil. This new species can be distinguished by its coloration pattern, pilosity and integumental sculpture. Field observations have revealed several aspects of its life history, such as mating behaviour (similar to other Arhysosage species) and its association with the host plant Opuntia sp. (Cactaceae). In addition, Arhysosage flava is recorded for the first time in Brazil, and type-specimen photographs of Arhysosage cactorum Moure, 1999 and Arhysosage melanothricha Moure, 1999 are provided, along with taxonomic notes.http://www.zoobank.org/urn:lsid:zoobank.org:pub:4E7C7FF9-44C0-4D77-8C78-B4E0F9C4831F
