Revisionary notes on the fungus-growing ant genus Mycetarotes Emery (Hymenoptera, Formicidae)

Evolution, systematics, and natural history of a new genus of cryptobiotic fungus‐growing ants

“…Simultaneous to, and potentially inspired by, the fundamental biological discoveries of Bates and his contemporaries, late 19th‐century entomologists described and classified many new species of fungus‐growing ants. Fundamental treatises of the 19th and early 20th centuries include taxonomic monographs and evolutionary hypotheses authored by foundational ‘attinologists’ such as Auguste Forel (, ,b), Carlo Emery (, , ), and William Morton Wheeler (, ), laying the basis for subsequent work by Borgmeier (), Gonçalves (), Kempf (, , , ), Kusnezov (), Wilson (), Brandão & Mayhé‐Nunes (, ), Mayhé‐Nunes & Brandão (, , , ), Rabeling et al . (, ), Klingenberg & Brandão (), Sosa‐Calvo & Schultz (), and Ješovnik & Schultz ().…”

First Record of the Genus Mycetarotes (Emery, 1913) (Formicidae: Myrmicinae) from Colombia

“…We sampled ants using pitfalls traps, following Agosti et al (2000). We based our measures on those used by Mayhé-Nunes and Brandão (2006), and carried them out using a Leica (80x) stereomicroscope at 60x magnification with an ocular micrometer. We measured: TL, total length; HL, head length (except mandibles); HW, head width (including eyes); IFW, inter frontal width (distance between the lateral margins of frontal lobes); ScL, scape length; WL, Weber's length (alitrunk length); CI, cephalic index (HW/HL x 100); and FLI, frontal lobes index (IFW/HW x 100).…”

“…The workers analyzed share all the diagnostic characters listed by Kempf (1960) and Mayhé-Nunes and Brandão (2006) for the genus Mycetarotes. We identified it as M. parallelus, which can be clearly distinguished by the following characters: two pairs of spines on the mesonotum (where other members of the genus have three pairs), well developed petiolar spines, postpetiole without a tooth near each side of the lateral anterior margin, weakly marked outer frontal carinae branches, and a deep circular impression on the dorsal surface of the postpetiole (Mayhé-Nunes & Brandão 2006). Additionally the specimen has an opaque integument, reddish-brown head color, yellowish legs and mesosoma, dark gaster with erect hairs absent and sparse appressed hairs.…”

A new species of the fungus-farming ant genus Mycetagroicus Brandão & Mayhé-Nunes (Hymenoptera, Formicidae, Attini)

“…The terminology follows Brandão and Mayhé-Nunes (2001), partially modified by Mayhé-Nunes and Brandão (2007). Measurements were taken using a Leica MZ 9.5 stereomicroscope at 60X magnifications.…”
