Sapotaceae is a large family of angiosperms which has predominantly tree species, and worldwide distribution in subtropical and tropical regions. The Neotropics are one of the greatest centers of diversity of Sapotaceae, and in Brazil, the family comprises 12 genera and 234 species, of which 103 species are endemic. We present here a taxonomic trea...

... According to Pennington (2004), unisexual species should be even more abundant in this group of plants than it was previously thought, but since the flowers are often hermaphrodite in appearance due to rudimentary sexual whorls, the sexuality of some species may have been misidentified. Within the genus Chrysophyllum, bisexual and unisexual flowers have been described (Pennington 2004(Pennington , 2006Völtz et al. 2020), but anatomical studies of these flowers are unknown. Based on morphological and pollination studies, Sigrist et al. (2021) described cryptic gynomonoecy in Chrysophyllum marginatum. ...
... On the other hand, based on morphological descriptions, Völtz et al. (2020), who recognized C. gonocarpum as a dioecious species, mentioned that this species does not present any staminodes. However, in the present study, staminodes in the form of small appendages were found in the pistillate flowers, whose anatomy is similar to that of the filament of staminate flowers. ...
... In general, the Pouteria species present staminodes in all floral types, in the hermaphrodite and staminate flowers these alternate with the stamens, while in the pistillate flowers they are vestigial (Pennington 2006;Alves-Araújo et al. 2014). In contrast, Chrysophyllum generally lacks staminodes (Pennington 2006;Völtz et al. 2020), except in a few species, such as C. pomiferum (Eyma) T. D. Penn., C. durifructum (W.A. Rodrigues) T. D. Penn., C. amazonicum T. D. Penn., and C. prieurii A. DC., in which the staminodes are vestigial (Pennington 2006). Chrysophyllum marginatum has recently been described by Sigrist et al. (2021) as a gynomonoecious species in which the pistillate flowers have stamens similar to the hermaphrodite flowers; i.e., they have filaments and anthers, but do not produce any pollen. ...
The Sapotaceae are a significant component of the humid forests of the Neotropics and have many species of economic interest. Chrysophyllum gonocarpum is one of them and its edible fruits have currently acquired a high commercial value. Since there are no studies that cover its floral anatomy and elucidate its sexual system, the objective of the present study is to describe these aspects based on field observations and a detailed anatomical analysis of their flowers. Conventional techniques of plant anatomy are implemented. The results indicate that the species presents cryptic dioecy, showing specimens with morphologically and functionally pistillate flowers (with reduced staminodes), and trees with morphologically hermaphrodite and functionally staminate flowers. In addition, data on floral nectaries and laticiferous are provided.
... Paraná state is situated in the subtropical region of South America, in southern Brazil, between the coordinates 22° 30′ 44′′ S and 26° 43′ 08′′ S, and 48° 00′ 11′′ W and 54° 36′ 32′′ W. It has a territorial area of 199,298 km 2 [83], comprising five phytogeographic regions: seasonal semideciduous forest, mixed ombrophilous forest, dense ombrophilous forest, steppe and savanna [84,85]. According to Köppen classification, the climate in Paraná is divided into subtropical and tropical, with an average annual temperature of 19°C (varying between 25.9 and 12°C), and average annual precipitation of 1300 mm [86]. ...

Biological collections are important for acquiring knowledge of the biodiversity of a specific environment. Here, we organize, list and catalog adult specimens of Culicidae from the Parasitology Collection of the Basic Pathology Department at the Federal University of Paraná, Brazil, and present a databank of taxonomic and collection information for each sample. Culicids were collected using different methodologies in 18 municipalities in Paraná state, between 1967 and 1999. There are 5,739 catalogued specimens, of which 4,703 (81.94%) are identified at species level, with a diversity of 100 species. Of these, 18 are new recorded samples for Paraná, and three are new for Brazil. This collection is named the Ana Leuch Lozovei Entomological Collection in honor of the 30 years Prof Lovozei dedicated to culicid study in Paraná. The collection comprises insect vectors or potential vectors, of agents causing human diseases.
