Fig. 6. Dyscolus osseus sp. nov., paratype, ♂, Otonga , Ecuador .

a. Habitus (with deformed left mesotibia).

b -c. Aedeagus. b. Lateral. c. Dorsal.

Diagnostic combination. – Pronotum trapezoidal with rounded hind angles;anterior lateral seta of the pronotum absent;striae discontinuous; strongspine atthe apex of the elytra;very long appendages; metafemora without any ventroposterior or anterior setae. This combination is unique,and atthe present state of knowledge, D. spinicauda sp. nov. has no close relatives in Ecuador. Dyscolus caulatus Moret, 1993 shares with D.spinicauda sp. nov. a spinose elytral apex and foveate striae,but in D. caulatus the pronotum has a different shape, more elongate and with a narrow base, and the setation pattern is quite different (lateroposterior seta of the pronotum absent, 3 d elytral interval asetose).
