Type locality. Caracas , Venezuela. 

Plant associations. None reported.

Distribution. Venezuela.

Remarks. This species was described from a single male that remains undissected ( Figs. 15–18 View Figure ). Fennah (1945: 431) stated that "[t]his species differs from occidentalis Muir  in the shape of the genitalia, especially the penis", which he had earlier in the same page described as “[p]enis narrowly tubular basally, with a wide, pendent, laterally compressed semimembranous appendage, devoid of teeth, arising sub-apically and reflected anteriorly ventrad” (see Fennah 1945, figures 88–89 in contrast to Muir 1926, figure 6). The holotype is externally very similar to occidentalis  . We suspect that gracilis  and occidentalis  may be the same species, with the difference cited by Fennah (1945) a result of the apex of the aedeagal process getting broken off; however, because we have only the holotype available, which is geographically segregated from the available specimens of occidentalis  ( Fig. 43 View Figure ), we cannot determine with confidence whether the two taxa represent the same or different species.
