Chirothrips frontalis Williams

Chirothrips frontalis Williams 1914: 51

Chirothrips salcatus John 1922: 345; Hood 1953: 115.

Distribution: Argentina, Kenya, South Africa, Australia (zur Strassen 1960).

Comments: According to Mound and Palmer (1972) C. frontalis Williams resembles C. bradleyi Hood (= praeocularis Andre) and is of American origin. However, it lacks diagonal ridges on antennal segment II, and median longitudinal ridge and other irregular longitudinal markings present on the head of C. praeocularis . Jacot- Guillarmod (1971) listed C. frontalis for the United States (Wyoming) but the source for this record was not indicated. One specimen previously determined as this species from Wyoming was located in the UCD collection and could be the basis for this record. However, this specimen is a misidentification of C. andrei . A record from Michoacan, Mexico (Johansen & Mojica-Guzman 1996) was not examined and therefore was not listed in the distribution.
