Abstract

Polymorphism and sexual dimorphism are common in insects. Thrips have been reported to exhibit intraspecific variation in body size, color and wing length (Mound 2005), also sexual dimorphism in abdominal pore plates, antennal sensoria and fore leg armature (Tyagi et al. 2008). Chilothrips Hood is a small genus that currently comprises seven species (ThripsWiki 2017), three from USA, one from Japan, and three from China. No male has been reported in the three species from China, C. strobilus, C. jiuxiensis and C. hangzhouensis (Hu & Feng 2015), and C. strobilus was described on three female specimens from cones of Pinus in Liaoning Province, northeastern China (Tong & Zhang, 1994). Recently, we have surveyed different parts of northeastern China and collected many male individuals of C. strobilus. We have observed that this species shows sexual dimorphism in mouth cone length, and remarkable variation in form of abdominal segment X among females.
