    Notes: Summary Leptothorax pergandei, the only member of the subgenusDichothorax, is a common ant in Chihuahuan desert habitats in southwestern Arizona. According to colony censuses and relatedness estimates, colonies are mostly monogynous and queens typically mate only once. Mating takes place in local swarming flights; virgin queens attract males with secretions from the poison gland. Some dealate queens running on the soil surface directly after the mating flight had well-developed ovaries containing mature eggs and yellow bodies.

    Notes: Summary By means of gas chromatography, gas chromatographic coupled mass spectrometry, trail-following experiments and electrophysiological recordings from worker antennae, the major trail pheromone components from the hindgut of the formicine speciesCamponotus atriceps andC. floridanus were identified as 3,5-dimethyl-6-(1′-methylpropyl)-tetrahydropyran-2-one and nerolic acid, respectively. The Dufour's gland contents of both species, investigated by gas chromatographic coupled mass spectrometry, show significant differences.
