Length of body: ♂ 17.11 (16.70–17.55), ♀ 17.65; length of fore wing: ♂ 17.85 (17.15–18.40), ♀ 18.15; width of fore wing: ♂ 6.66 (6.45–6.85), ♀ 6.60; length of head: ♂ 2.86 (2.7–2.95), ♀ 2.70; width of head including eyes: ♂ 5.59 (5.35–5.80), ♀ 5.65; width of pronotum including suprahumeral plates: ♂ 5.93 (5.60–6.30), ♀ 6.05; width of mesonotum: ♂ 5.21 (4.90–5.50), ♀ 5.05. Song. (n=7: holotype , 2 paratypes , and 4 uncaptured males from Maule Region , Colchagüa Pr.) A unique combination of a brisk 9.50± 0.37 s- 1 repetition rate of short echemes of duration 0.07± 0.00 s . The dominant frequency band is 9.87–12.03 kHz (mean dominant frequency=10.92±0.19 kHz). Diagnosis. Another of the smaller of the Chilecicada species. This new species can be distinguished by having in combination a body length between 16.70–17.65 mm , fore wing length between 17.15–18.40 mm , fore wing basal cell about 3.14 times longer than broad, ground color proximal fore wing basal cell, no fascia separating the fore wing costa and radius + subcostal veins, a triangular meracanthus, a piceous mark on the medial opercular margin, semicircular posteromedial operculum, abdominal epipleurites with a central spot, and a narrow uncus that is piceous with ground color dorsal fascia with the distal third bent. The rapid echeme song resembles the songs of C. citatatemporaria and C. occidentis but is half the rate of those species. Distribution. The species is known from the type series collected in multiple localities in the Metropolitana and O’Higgins Regions of central Chile .
