Host. Corythopis delalandi (Lesson, 1831) — Southern antpipit (Passeriformes: Tyrannidae) Locality. Kanguery Biological Station, San Rafael National Park, Paraguay (26 ° 30 ´ S, 55 ° 47 ´ W, 183 m a. s. l.)
Diagnosis. This Ricinus species belongs to the marginatus species-group by having three nodi, frontal margin not continuous with lateral margin, monomorphic mandibles without fingerlike articulation, and without evident ovoid sclerite. However, these females are distinguishable from females of all other species of the marginatus species-group by the presence of 2 lateral, short equally long setae on tergites II – VIII. Also, they differ from females of R. dalgleishi, R. emersoni, R. flavicans, R. marginatus, R. pallens and R. seiuri by the absence of a 6 setae. Unlike most species of the marginatus species-group, which have 14 pairs of setae on the labium, our specimens have 12 pairs of labial setae; therefore, this feature separates them from R. dalgleishi, R. dendroicae, R. emersoni, R. flavicans, R. marginatus, R. pallens, R. picturatus and R. seiuri. Within the marginatus species-group, R. frenatus is the only species with long a 1 seta and antennal lappets composed of 6 setae, compared to 12 – 13 setae in our specimens. Considerably smaller antennal lappets are also present in R. polioptilus, which in addition has w series composed of 7 setae compared to our specimens which have only 5 setae.
