Anurans emit calls that convey different messages, depending on the context of emission. Reproductive calls mediate intraspecific interactions in reproductive contexts, and among these calls, the advertisement call is the most conspicuous and described type of call. It serves to attract mates, signalize aggression between conspecific males, and maintain space between chorus calling frogs. Another reproductive call, the release call, is emitted by males and females to signal non-receptiveness to a conspecific, or not, amplexus. Boana Gray, 1825, is a species-rich genus with a wide distribution in the Neotropical region, and the Boana faber species group (nested within Boana) is composed of nest-building gladiator frogs that use prepollical spines to defend their territory. The advertisement call is known for all species in the B. faber species group; however, the male release call is only known for one species of the group. Furthermore, the male release call is only known for five of the 101 species of Boana. In this study, we describe for the first time the male release call of Boana crepitans and Boana faber. Make intrageneric acoustic comparisons among the known male release calls for Boana. The male release call of both species is composed of a single type of note. Pulsed notes are ubiquitous in B. crepitans, but they can be pulsed, pulsatile, or non-pulsed in B. faber. Besides the temporal envelope, notes presented differences in duration: 209–449 ms in B. crepitans and 5–80 ms in B. faber, and in pulse repetition rate: 19–25 pulses/s in B. crepitans and 147–156 pulses/s in B. faber. Expanding our acoustic comparisons to Boana, we found much variation in the few described release calls for the genus. Our study also reveals the rarity of described male release calls for Boana, and, finally, we expanded the known male release calls descriptions to seven of the 101 known Boana species.
In this contribution, male and female of the new species of oil-collecting bees Tetrapedia australis are described. Individuals reared from trap nests allowed the correct association of the sexes. The range of distribution of this new species considerably extends the known southern limits of distribution of the genus.
Halacarid mites are a diversified secondarily marine clade comprising more than one thousand species. Despite recent progress, it may be regarded as a neglected group of animals in Brazil, with only 36 species reported from Brazilian coastline, 26 of them from São Paulo State, belonging to 12 genera. Original description and records included material deposited in personal collections now housed at the Acarological Collection at “Centro de Coleções Taxonômicas da UFMG”, acronym UFMG-AC. In addition to individuals employed in taxonomcal studies, other individuals deposited in this collection are reported, specially those obtained by researchers of BIOTA-FAPESP program, making the information available to the scientific community. Problems related to the identity of Agauopsis brevipalpus (Trouessart, 1889), Copidognathus floridensis (Newell, 1947) and Rhombognathus levigatoides Pepato & Rocha, 2007 are presented, and distribution of Simognathus fuscus Viets, 1936 is discussed under the light of molecular data. We concluded that Brazilian occurrences of Agauopsis brevipalpus must be rejected, and confirm that Simognathus platyaspis Otto, 2000 must be regarded as a junior synonym of S. fuscus.
The Entomological Collection of the Center of Taxonomic Collections (CCT-UFMG) at the Federal University of Minas Gerais is a significant repository of insect specimens, housing a diverse range of orders and providing invaluable resources for taxonomic and ecological research. With over 245 thousand registered specimens, it stands as the largest collection within the CCT-UFMG. This paper presents a catalog of the collection's insect type specimens, excluding Odonata. The cataloging process involved examination of digital databases, scientific literature, and specimen labels to identify and document type specimens and their associated information. For each taxon we provide the bibliographic reference containing the original description, preservation method, sex, the number of specimens deposited in the CCT-UFMG, geographic distribution, and notes on inconsistencies with the literature. For holotypes and neotypes, we also describe the data label and the condition of the 88 specimens. Hymenoptera predominates with 77 holotypes and neotypes (87% of the total), of which 53 are bees. Other orders represented in holotypes include Coleoptera (1), Hemiptera (8), Mecoptera (1), and Phasmatodea (1). Paratypes encompass 130 species across six orders: Coleoptera, Diptera, Hemiptera, Hymenoptera, and Phasmatodea, with Hymenoptera again being the dominant order, comprising 543 paratypes of 112 species, including 78 species of bees (74% of total paratypes).
Fernando Amaral da Silveira (1960-2022) was one of the most important bee taxonomists and systematists, with work of global relevance, even though he left early, at just 62 years old. Among his many achievements, he dedicated much of his energy and enthusiasm to the maintenance of Lundiana: International Journal of Biodiversity. Therefore, we consider that the publication of this volume, in which the authors dedicated their articles to his memory, is a due tribute.
