Genus Euphyllodromia Shelford, 1908

History

Euphyllodromia , first described by Shelford in 1908 as a subgenus of Pseudophyllodromia Brunner Von Wattenwyl, 1865 , was established as a full genus by Hebard (1920). Since then the genus has expanded to include 42 species. The most recent review of the genus was done by Anisyutkin (2011) who also described three species, and described a fossil E. angustata ( Latrielle, 1811) from the Pleistocene – Holocene epoch.

Euphyllodromia are characterized by the following traits. Sizes range from 11 to 19 mm long, and they possess unique pigmentation. The eyes protrude and the triangular head remains uncovered by the pronotum. The wings and tegmina are well developed. A few spines are present on the basal half of anteroventral margin of the front femur, which precede smaller, chitinous spines and three slender apical spines (2 preapical and one 1 apical). Pulvilli are present only on the fourth tarsal segment (Rocha E Silva Albuquerque 1984). In addition, they also have a phallomere that is both hooked on the right side in the dorsal view and in possession of a pre-apical incision ( Lopes & da Silva 2012).
