Measurements (mm). n= 2♂, mean (range). Length of body: ♂ 16.35 (15.75–16.95); length of fore wing: ♂ 17.30 (16.60–18.00); width of fore wing: ♂ 6.38 (6.15–6.60); length of head: ♂ 3.10 (3.00–3.20); width of head including eyes: ♂ 5.33 (5.15–5.50); width of pronotum including suprahumeral plates: ♂ 6.30 (6.15–6.45); width of mesonotum: ♂ 5.13 (5.00–5.25).
Song. (n=4: 1 paratopotype, 2 topotypes (UCMS alcoholic molecular vouchers), 1 male from type locality not captured) Brief echemes of 0.04± 0.00 s duration delivered at a rapid rate of 18.13± 0.89 s- 1. The dominant frequency band is 9.84–12.59 kHz (mean dominant frequency=11.18±0.61 kHz). Echemes are grouped into echeme sequences that vary widely in length, from 1.67 to 24.51 s. The songs of C. citatatemporaria and C. occidentis are not significantly different (MANOVA, P =2.90×10 -1).
Diagnosis. This is one of the smaller of the Chilecicada species. This new species can be distinguished by having in combination a body length between 14.75–16.95 mm, fore wing length between 15.30–18.00 mm, fore wing basal cell about 3.67 times longer than broad, a piceous mark along the proximal fore wing basal cell, a piceous fascia separating the fore wing costa and radius + subcostal veins to node, a triangular meracanthus, ground color medial opercular margin, a semicircular posteromedial operculum, abdominal epipleurites with a central spot, and an uncus that is piceous proximally and ground color distally curving distally to terminus.
Rapid sequences of echemes separate the song of this species from all other Chilecicada except C. occidentis. The echeme rate is also rapid in C. viridicitata songs but is half (~10 s-1) the C. citatatemporaria rate (~20 s-1).
Distribution. The species is known from the type series collected in the Petorca Province of Región de Valparaíso of central Chile.
