Dysonia simplicipes (Brunner)
1878. A[phidnia] simplicipes Brunner, Monogr. der Phaneropt., p. 157. [male, Mexico.]
Chocó of western Colombia, 1 male, [A. N. S. P.J.
This is an intensively marked specimen, the black spots and dots being all heavier than in Costa Rican males before us. With these the present individual agrees closely in structure and coloration, except that the cerci, instead of being white, are black. Due to intensification of the color pattern the adjacent black dots meso-cephalad on the pronotal lateral lobes are fused in a single black spot.
The presence in our unstudied collections of Peruvian material which agrees with the description of simplicipes, but upon examination is found to include three species, separable by male cercal differences and less striking features of maculation, shows that the phylum probably breaks into a number of species. Without Mexican material we can not, therefore, determine definitely whether the Costa Rican and Colombian specimens, though agreeing with the description of simplicipes, represent the same or a very closely allied species.
