Studies in Neotropical ant diversity

This study is divided into two parts: first, an inventory of the ant fauna of two plateaus in Eastern Suriname and, second, a series of taxonomical studies of ant genera belonging to the ant tribes Attini and Dacetini, and the ant subfamily Proceratiinae for the Neotropics. The first part describes the results of a rapid assessment program survey of the leaf-litter ant fauna that was conducted in Eastern Suriname with the goal of informing conservation decisions by mining companies, governments, and individuals. The second part deals with descriptions of three new species and 15 new distributional records for species in the genera Pyramica, Strumigenys, and Acanthognathus (Formicidae: Dacetini) for Panama and Guyana; a review of the ant subfamily Proceratiinae for Colombia; and the descriptions of three remarkable new species in the fungus-growing ant genus Myrmicocrypta (Formicidae: Attini) from Brazil

Nesting Biology and Fungiculture of the Fungus-Growing Ant, Mycetagroicus cerradensis: New Light on the Origin of Higher Attine Agriculture

The genus Mycetagroicus is perhaps the least known of all fungus-growing ant genera, having been first described in 2001 from museum specimens. A recent molecular phylogenetic analysis of the fungus-growing ants demonstrated that Mycetagroicus is the sister to all higher attine ants (Trachymyrmex, Sericomyrmex, Acromyrmex, Pseudoatta, and Atta), making it of extreme importance for understanding the transition between lower and higher attine agriculture. Four nests of Mycetagroicus cerradensis near Uberlândia, Minas Gerais, Brazil were excavated, and fungus chambers for one were located at a depth of 3.5 meters. Based on its lack of gongylidia (hyphal-tip swellings typical of higher attine cultivars), and a phylogenetic analysis of the ITS rDNA gene region, M. cerradensis cultivates a lower attine fungus in Clade 2 of lower attine (G3) fungi. This finding refines a previous estimate for the origin of higher attine agriculture, an event that can now be dated at approximately 21–25 mya in the ancestor of extant species of Trachymyrmex and Sericomyrmex

Biogeography of mutualistic fungi cultivated by leafcutter ants

Leafcutter ants propagate co-evolving fungi for food. The nearly 50 species of leafcutter ants (Atta, Acromyrmex) range from Argentina to the United States, with the greatest species diversity in southern South America. We elucidate the biogeography of fungi cultivated by leafcutter ants using DNA sequence and microsatellite-marker analyses of 474 cultivars collected across the leafcutter range. Fungal cultivars belong to two clades (Clade-A and Clade-B). The dominant and widespread Clade-A cultivars form three genotype clusters, with their relative prevalence corresponding to southern South America, northern South America, Central and North America. Admixture between Clade-A populations supports genetic exchange within a single species, Leucocoprinus gongylophorus. Some leafcutter species that cut grass as fungicultural substrate are specialized to cultivate Clade-B fungi, whereas leafcutters preferring dicot plants appear specialized on Clade-A fungi. Cultivar sharing between sympatric leafcutter species occurs frequently such that cultivars of Atta are not distinct from those of Acromyrmex. Leafcutters specialized on Clade-B fungi occur only in South America. Diversity of Clade-A fungi is greatest in South America, but minimal in Central and North America. Maximum cultivar diversity in South America is predicted by the Kusnezov–Fowler hypothesis that leafcutter ants originated in subtropical South America and only dicot-specialized leafcutter ants migrated out of South America, but the cultivar diversity becomes also compatible with a recently proposed hypothesis of a Central American origin by postulating that leafcutter ants acquired novel cultivars many times from other nonleafcutter fungus-growing ants during their migrations from Central America across South America. We evaluate these biogeographic hypotheses in the light of estimated dates for the origins of leafcutter ants and their cultivars

SYSTEMATICS OF THE CRYPTIC FUNGUS-FARMING ANT GENUS Myrmicocrypta FR. SMITH, WITH THE DESCRIPTION OF A NEW GENUS AND SPECIES OF FUNGUS-FARMING ANTS (HYMENOPTERA: MYRMICINAE).

Fungus-farming ants (Hymenoptera: Formicidae) have become model systems for exploring questions regarding the evolution of symbiosis. However, robust phylogenetic studies of both the ants and their cultivars are needed to address whether or not the attine ant symbiosis is a result of strict or diffuse coevolution. Chapter One, deals with the relationships of the species within the ant genus Myrmicocrypta, and their fungal cultivars. Analyses conducted, recovered the genus as monophyletic and the sister group of Mycocepurus. In addition, the species M. tuberculata was recovered as the sister to the rest of Myrmicocrypta. The time-calibrated phylogeny recovered the age of stem-group Myrmicocrypta plus its sister group as 35.16 Ma, whereas the inferred age for the crown-group Myrmicocrypta was recovered at 30.05 Ma. Chapter Two, represents the first species-level taxonomic revision of the fungus-farming ant genus Myrmicocrypta. Myrmicocrypta is distributed in the New World tropics from Mexico to northern Argentina, and, as far as it is known, absent in the Caribbean and in the fossil record. Sixty-five species are recognized, of which 37 are described as new species. The revision includes a taxonomic key to the species of Myrmicocrypta based on the worker caste. When possible, descriptions and photographs of the reproductive forms (i.e., queens and males), geographic distribution, and notes on natural history are presented. Finally, Chapter Three, deals with the description of Cyatta abscondita, a new genus and species of fungus-farming ant from Brazil, based on morphological study of more than 20 workers, two dealate gynes, one male, and two larvae. Ecological field data are summarized, including natural history, nest architecture, and foraging behavior. Phylogenetic analyses of DNA sequence data from four nuclear genes indicate that C. abscondita is the distant sister taxon of the genus Kalathomyrmex, and that together they comprise the sister group of the remaining neoattine ants, an informal clade that includes the conspicuous and well-known leaf-cutter ants. Morphologically, C. abscondita shares very few obvious character states with Kalathomyrmex. It does, however, possess a number of striking morphological features unique within the fungus-farming tribe Attini. It also shares morphological character states with taxa that span the ancestral node of the Attini. The morphology, behavior, and other biological characters of C. abscondita are potentially informative about plesiomorphic character states within the fungus-farming ants and about the early evolution of ant agriculture

B e n t o n) [CPDC]. Gyne and male. Unknown. Range. This species is known to occur in Iquitos, Peru, and Manaus, Brazil. Etymology. It gives us great pleasure to name this ant in honor of Mr. Barry Bolton for his extensive contributions to the study of ant taxonomy and, especially, to the taxonomy of the tribe Dacetini. His worldwide revision of the tribe Dacetini is a monumental, well-documented work containing well-executed SEM micrographs and a very user-friendly taxonomical key that facilitates identification of the many miniscule, curious species of the tribe. Habitat. This species seems to be an exclusively canopy-dwelling ant. The Peruvian specimens were collected on a Sloanea sp. (Elaeocarpaceae) tree. Worker variation. Among the specimens studied, some morphological variation has been documented, including: (i) All castes with sides of head lacking a broad gap between bases of mandibles and margins of head capsule when mandibles are fully closed, with the exception of the two minor workers studied, in which case there is a narrow gap. (ii) Erect hairs on the ocular crest are present in all workers examined. However, the number of hairs varies among specimens. We suspect that these hairs are fragile and can be easily lost, which may account for the variation observed between specimens. This seems also to apply to the standing hairs on the median promesonotum and behind the posterior tubercles of the promesonotum. (iii) Humeral tubercles are strongly reduced, sometimes forming a carina or absent, especially in smaller workers. (iv) The propodeal spines of all of the Peruvian specimens examined converging at the tips (U-shaped, when seen in fronto-dorsal view), whereas in most of the specimens from Brazil the propodeal spines are diverging, more like the state in D. armigerum. (v) Petiolar spines short, almost absent in the smaller castes. The petiolar spines are more developed in the specimens from Brazil.Published as part of Azorsa, Frank & Sosa-Calvo, Jeffrey, 2008, Description of a remarkable new species of ant in the genus Daceton Perty (Formicidae: Dacetini) from South America, pp. 27-38 in Zootaxa 1749 on pages 32-36, DOI: 10.5281/zenodo.18170

This variation includes: (i) Lateral spines bifurcate, the posterior spine projecting upwards and curving at the tip in major workers, whereas in small or median workers this spine not curving at the tip. In small workers the posterior spine is very short, almost vestigial when viewed in profile, but conspicuous in dorsal view. (ii) Short, simple, and appressed hairs present on the first gastral tergite in some individuals from Brazil and Peru. On other workers, hairs on the first gastral segment are absent. (iii) Humeral spines, in smaller workers, vestigial or present as very low carinae. Median and larger-sized workers with humeral tubercles that are spinose or acute. (iv) The posterior pair of petiolar tubercles reduced, rounded and low in smaller workers, whereas tubercles acute in larger workers. (v) Large workers with posterior promesonotal tubercles truncate and flattened in profile. (vi) Anterior spines of petiole long and diverging with intervening space concave or with intervening space discontinuous. Anterior spines of petiole in smaller workers shorter than in other castes.Published as part of Azorsa, Frank & Sosa-Calvo, Jeffrey, 2008, Description of a remarkable new species of ant in the genus Daceton Perty (Formicidae: Dacetini) from South America, pp. 27-38 in Zootaxa 1749 on pages 30-32, DOI: 10.5281/zenodo.18170
