Diagnosis Species of Choeradoplana with dorsal color pattern mottled with brownish speckles. CMI, 15–27%. Sperm ducts penetrate antero-ventral wall of penis bulb. Copulatory apparatus relatively compact. Prostatic vesicle intrabulbar, with proximal half canalicular and oriented dorsally. No permanent penis papilla. Male:female atrial length ratio, 1.6–2.9.

Molecular diagnosis This species includes all populations that cluster with individuals MZUSP PL 512, MZUSP PL 514, MZUSP PL 516, MZUSP PL 519, MZUSP PL 521– 25, MZUSP PL 528–35, MZUSP PL 651, MZUSP PL 537– 39, MZUSP PL 1160–62, MZUSP PL 1164, and MZU PL 155–58 ( Table 1) from this study, with significant support in an adequate molecular delimitation model.

Geographic distribution and habitat Municipalities of Taquara, Parobé, São Francisco de Paula (State of Rio Grande do Sul, Brazil). The species was found in Atlantic forests, in exotic forest plantations, and human-modified environs.
