Distinguishing features

Similar in structure to M. floridensis but with curved sculpture lines medially on the pronotum.

Related species

Although listed from California by Hoddle et al. (2004), no specimens of M. morgani have been studied by the present authors from west of Texas. This eastern North American species is similar in general body form to M. floridensis, but has distinctively curved sculpture lines on the median area of the pronotum. The only other species with similar pronotal sculpture is M. yii from Malaysia. A total of 14 extant species are listed in the genus Merothrips, all from the warmer parts of the world, and there are a further three species described from Baltic Amber fossils.
