Polycentropus charlesi Ross, 1941: 74. [ Typelocality: United States, Texas, San Felipe Springs, DelRio; INHS; male];— Flint, 1968:21[to Polyplectropus]. Polyplectropus charlesiis most similar to P. kylistosbased on the pronounced ventral median projection of sternum IX, the lobate, rounded intermediate appendage, the broadly separated ventral branches of the inferior appendage, and the overall shape of the dorsal branch of the inferior appendage. In addition, P.charlesiand P. kylistosbear peg-like setae on both branches of the inferior appendage (absent in P. exilis). Some specimens of P. charlesiwith an apically narrowed dorsal branch have subapical spines on a small membranous stalk, similar to those found in P. kylistos. However, in P. kylistosthese stalked spines are located more basally and proximal to the ventral branch. Polyplectropus charlesican also be distinguished from P. kylistosby the shorter, apically rounded ventral branch of the inferior appendage, by the broader and sometimes slightly narrower and less arched dorsal branch of the inferior appendage, by the less acute apices of the mesoventral process of the preanal appendage, and by the posteriorly directed endothecal phallic spines (directed laterad in P. kylistos).
Adult.Length of forewing 3.5–7.8 mm, n = 213. Color of head, thorax, and legs yellowish-brown.

Mexico, Nicaragua, Panama, and USA( Flint et al. 1999). Remarks. The dorsal branch of the inferior appendage varies across the entire range of this species. The holotypehas an apically broader dorsal branch of the inferior appendage, becoming narrower in other specimens. Even though the different forms have been collected from the same localities, no 2 forms were collected together. The observed variability of the dorsal branch among the specimens examined was not discrete, but instead was continuous. When the dorsal branch is apically broad, 2 (or sometimes more) apical spines are present. In the narrower dorsal branches, these spines are retained but the more basal spine also retains a small basal process or stub. This spine-and-stub complex resembles those present on the inferior appendage of P. kylistos( Fig. 58A). However, in P. kylistosthe spine-and-stub complex is basal and closer to the ventral branch.
