Differentiation. Easily distinguished from all other species of the genus by the distinctively triangular protuberances on the tegmina, which are covered with many small, yellowish granules.

Description. ♀. Of small size for the genus. Length of body 48.0–57.0 mm. Tegmina bearing distinctively raised, triangular lobes on their central protuberance, which vary in size. Colouration very variable; general colour of body and legs mid brown, ventral surface of body paler brown with irregular dark fields on pro-, meso- and metasternum and a broad, longitudinal ventromedian black streak along sternum I–VII. Head, pronotum and mesonotum shiny but rugose, no spines present. Antennae irregularly annulated in dark brown and drab yellow in apical half. Tegmina and costal area of alae brown to greenish grey with indistinct and irregular pale mottling and speckles. Angulate central protuberances of tegmina set with small rounded yellow to dark orange granules. Anal area of alae uniformly brown. Subgenital plate flat, broadly rounded and produced into a trapezoid lobe medially, reaching at best posterior margin of sternum IX. Legs brown, in some specimens having a transverse black band on the meso- and/or metafemora.

♂ ( Figs. 46 iView FIGURE 46, 47 iView FIGURE 47). Length of body 36.0–40.0 mm. Very similar to ♀, but smaller. Poculum small and flat, reaching to centre of anal segment, posterior margin rounded with median incision. Vomer large, triangular with pointed apex reaching posterior margin of anal segment.

Comments. Prisopus ariadne Hebard, 1923  was originally described based on a ♀ from Costa Rica and a ♂ and ♀ from Panama. The ♀ paratype from Panama in USNM could not be traced and hence is believed lost. Gün- ther (1938: 123) recorded the species from Colombia. The specimens at hand from French Guiana and Suriname differ from Costa Rican specimens and the type specimens consequently by the slightly less granulated thorax, the more distinctly pronounced and pointed protuberances of the tegmina and the distinct black marking on the ventral surface of the mesofemora.

Distribution. Likely to be distributed from Costa Rica in the northwest to French Guiana in the east, but not yet recorded from Guyana. The southernmost record of this species is from the Amazon lowlands of eastern Peru.
