ABSTRACT
Ageniella Banks is the second most diverse genus in the tribe Ageniellini (Pompilidae: Pepsinae) with about 200 valid names. Ageniella is known to be paraphyletic; yet, no revision has been made. Lack of a taxonomic catalogue and of identification keys has further delayed taxonomic studies. Additionally, many of the currently valid names should be treated as synonyms. This present study is the first attempt to organize the species of Ageniella, focusing on the species occurring in Brazil. A total of six subgenera and 40 species of Ageniella occur in Brazil. Of these, 25 species are endemic to Brazil. The new synonyms are proposed for (valid names are first): Alasagenia Banks, 1944 =Lissagenia Banks, 1946, syn. nov.; Ageniella (Alasagenia) erichsoni Banks, 1944 =Priophanes major Banks, 1945, syn. nov.; Ageniella (Ameragenia) zeteki (Banks, 1925) =Priophanes marcida Banks, 1946, syn. nov.; Ageniella (Ameragenia) agitata (Smith, 1873), comb. nov. =Salius (Priocnemis) setaceicornis Fox, 1897, syn. nov.; Ageniella (Ameragenia) sanguinolenta (Smith, 1864) =Agenia ruficeps Smith, 1864, syn. nov.; =Ageniella alternata Banks, 1946, syn. nov.; Ageniella (Priophanes) dolorosa (Banks, 1946), comb. nov. =Priophanes plagosa Banks, 1946, syn. nov.; Ageniella (Ameragenia) fabricii (Banks, 1944) =Ameragenia notabilis Banks, 1946, syn. nov. A new combination is proposed for: Ageniella (Alasagenia) cursor (Smith, 1873), comb. nov. (from Agenia Schiødte); Ageniella (Ameragenia) clypeata (Fox, 1897), comb. nov. (from Salius Fabricius), Ageniella (Ameragenia) rutila (Fox, 1897), comb. nov. (from Salius), Ageniella (Priophanes) tegularis (Fox, 1897), comb. nov. (from Salius), Ageniella (Priophanes) rufitarsis (Fox, 1897), comb. nov. (from Salius), Ageniella (Ameragenia) citricornis (Fox, 1897), comb. nov. (from Salius), Ageniella (Ameragenia) serrula (Fox, 1897), comb. nov. (from Salius), Ageniella (Priophanes) cingulata (Fox, 1897), comb. nov. (from Agenia). A new name Ageniella (Ameragenia) banksii Waichert, nom. nov. is proposed for Ameragenia festina Banks, 1946, secondary homonym of Ageniella festina Banks, 1917, and Ageniella (Priophanes) otiosa is reinstate, stat. resurr.

Embora comuns em todo o Brasil e com grande importância médico-sanitária, os escorpiões ainda têm seu comportamento pouco estudado. Este estudo objetivou descrever o etograma de Tityus serrulatus, em cativeiro. Foram analisados 41 indivíduos, seis adultos e 35 filhotes, no período de abril a junho de 2011. Foram realizadas 61 horas de observações e doze atos comportamentais foram descritos e classificados em sete diferentes padrões de comportamento: imobilidade, forrageamento, interações com indivíduos da mesma espécie, os cuidados dos pais, ecdise, limpeza e hidratação. Comparativamente os animais apresentaram um menor número de atos comportamentais que o previsto na literatura. Sugere-se que imaturos apresentem um repertório comportamental menos diversificado que os adultos.
Although common in Brazil and with great medical and sanitary importance scorpions have yet understudied behavior. Here we describe the ethogram of Tityus serrulatus comparing with the existing literature. We analyzed 41 individuals, six adults and 35 puppies in the period April-June 2011. The study was conducted entirely in captivity. Were performed 61 hours of observations and twelve behavioral acts were described and classified into seven different patterns of behavior: immobility, foraging, interactions with conspecifics, parental care, moulting, cleansing and moisturizing. Compared animals showed fewer behavioral acts that provided in the literature. It is suggested that immatures have a behavioral repertoire is less varied than adults.
