levyi, with energy at 7 kHz and from 11 to 24 kHz, are likely the result of exciting radiating tegminal
speculae into action, these then vibrating at their inherent resonance frequencies (Montealegre-Z et al.
1c,e,g,h); male stridulatory organ not protruding beyond the level of posterior tegminal
margin; Cerci of male much thinner than second antennal segment very slightly and gradually widened and barely flattened outer margin (Fig.

8); distal part of tegmen almost twice as narrow as widest part of proximal half (except in region of stridulatory apparatus); tegminal
apex narrowly rounded; tegminal
subcostal area almost without crossveins; tegminal

venation, stridulation Introduction
Females practically apterous (minute tegminal
lobes, hardly visible looking from behind under pronotum).
In one of the two females examined the elytra are shorter, just reaching the sixth abdominal tergite, showing that tegminal
length is variable in this species).
Unlike in most other Tettigonioidea, female phaneropterines also usually possess tegminal
All of its winged species have females with tegminal
stridulatory organs, and in a few species with completely reduced female tegmina, these organs are lost.
These groups can be distinguished by characteristics including: song type (chirping vs trilling and continuous vs interrupted); tegminal
morphology; coloration of the head, pronotum, and abdomen; antennae color; and antennal markings on the pedicel and scape.
pads slender, considerably surpassing second abdominal tergite; length three times greater than width, gradually expanding to their rounded apices; venation prominent, longitudinal, fairly regular.
vein nomenclature follows that used by Ragge (1955).
