Abstract
Coptotermocola clavicornis gen. & sp. n. and Neotermitosocius bolivianus gen. & sp. n. of the termite inquilinous tribe Termitohospitini are described from peninsular Malaysia and Bolivia, respectively. The Termitohospitini are most readily diagnosable by the distally migrated anterior tentorial pits that are no longer associated with the antennal fossae, and by the enlarged vertex which obscures the antennal fossae dorsally. Additionally, the Termitohospitini are hypothesized to share a recent common ancestor with the Masuriini and Myllaenini due to shared derived morphologies of the lacinia distal teeth with lateral cuticular processes, presence of a unique maxillary palpomere III sensilla, and anterolateral angles of mentum produced. Habitus photographs and illustrations of diagnostic features are provided for the two new genera in order to facilitate future work.
Highlights
Eusocial insect colonies are often accompanied by a unique faunal assembly that takes advantage of available colony resources (e.g. Hölldobler and Wilson 1990, Wheeler 1928)
Illustrations of diagnostic features, a new tribal diagnosis as an update to previous diagnoses (Seevers 1941, 1957), and putative synapomorphies that support a close relationship of Termitohospitini with Masuriini and Myllaenini
Specimens of a new genus collected at the site for this study were initially preserved in 2.0 ml vials of 80% ethanol
Summary
Eusocial insect colonies are often accompanied by a unique faunal assembly that takes advantage of available colony resources (e.g. Hölldobler and Wilson 1990, Wheeler 1928). Mid leg (Fig. 15) with coxa oval; trochanter small; femur narrowed apically; tibia thin, slightly dilated subapically, one macroseta present on dorsal surface; tarsomeres subequal in length.
