Thrips of California 2012

Chilothrips rotrameli

Recognition data

Distinguishing features

This species has not been studied by the present authors. It is based on a single female with the tenth abdominal segment elongate, as in C. occidentalis, but with the head and mouth cone greatly enlarged.

Related and similar species

The species of Chilothrips are similar to Oxythrips species, but have the mouth cone unusually elongate. Five species have been described, three from North America, one from China and one from Japan. The two species from California described by Stannard (1973), C. occidentalis and C. rotrameli, both have the tenth abdominal tergite exceptionally elongate, whereas C. pini was described from Maryland with a more normal tenth tergite. The only specimens from California that have been studied by the present authors agree with the character states given for C. pini, but there is a possibility that several species exist in this genus, each breeding within the male cones of specific members of the genus Pinus or Cupressus.
