Distal plate oval, broad basally, emarginate api- cally, forming two lateral lobes. Basal plate absent. Spermathecal apodeme elongate, widely bifurcate basally, not reaching apical emargination. The male terminalia of P. speciosa are indistinguishable from those of P. braueri although these species can be separated by the characters of the basal band. In the holotype of P. braueri, the ventral parameres are very similar to those of P. speciosa in being branched, but the mesal branch in P. braueri is.

In females the genital plate of P. speciosa is much longer than it is in P. braueri. This species has been collected abun- dantly in Illinois on stinging wood net- tle, jewelweed, and poison ivy in hu- mid shaded areas along slow-moving streams. P. speciosa is a north-central species extending from Arkansas and Tennessee to Minnesota and Wisconsin (Fig. 183). Illinois Records.—(Fig. 183). Col- lected frequently from late April until early November. The prolonged collec- tion period indicates the possibility of two generations per year.
