Abstract
A new species ofOecanthusis described from Mexico.Oecanthus rohiniaesp. nov.occurs in central Mexico in the understory of tropical deciduous forest and is currently known only from Mexico. This new species has the coloring, antennal markings, slightly widened tegmina, and calling song that are found in therileyispecies group. Although morphologically very similar toOecanthus fultoni, the shapes of the distal hooks on the male copulatory blades differ between the two species. There are also differences in the song pulse patterns and chirp rate response to temperature. This new species has been given the common name Cri-Cri tree cricket. Video and song recordings are available online.
Highlights
According to the Orthoptera Species File (Cigliano et al 2020), the subfamily Oecanthinae Blanchard, 1845, is represented by nine genera: Oecanthodes Toms & Otte, 1988; Oecanthus Serville, 1831; Viphyus Otte, 1988; Leptogryllus Perkins, 1899; Prognathogryllus Brunner von Wattenwyl, 1895; Thaumatogryllus Perkins, 1899; Neoxabea Kirby, 1906; Xabea Walker, 1869; and Paraphasius Chopard, 1927
Four species in the rileyi species group are currently known to occur in North America, Central America and the Caribbean (Walker 1967, Collins et al 2014): O. alexanderi Walker, 2010 (Walker and Collins 2010); O. allardi Walker & Gurney, 1960; O. fultoni Walker, 1962; and O. rileyi Baker, 1905
We described a new species of Oecanthus that falls into the rileyi species group
Summary
According to the Orthoptera Species File (Cigliano et al 2020), the subfamily Oecanthinae Blanchard, 1845, is represented by nine genera: Oecanthodes Toms & Otte, 1988; Oecanthus Serville, 1831; Viphyus Otte, 1988; Leptogryllus Perkins, 1899; Prognathogryllus Brunner von Wattenwyl, 1895; Thaumatogryllus Perkins, 1899; Neoxabea Kirby, 1906; Xabea Walker, 1869; and Paraphasius Chopard, 1927. Two of these genera occur in Mexico—Oecanthus and Neoxabea. No further investigations of chirping tree crickets are known to have occurred in Mexico until the description of O. mhatreae Collins & Coronado, 2019 (Collins et al 2019)
