Both sexes of two sympatric and sexually dimorphic species, Sovia lucasii (Mabille, 1876) and S. lii Xue, 2015, are associated based on DNA barcoding using the COI (mitochondrial cytochrome coxidase I) gene. The females are thus identified for the first time, and their wing patterns and genitalia are described and illustrated for the convenience of morphological identification hereafter. A new ...

Xylella fastidiosa (Xf) is a plant pathogenic bacterium that is transmitted between hosts by the glassy-winged sharpshooter (GWSS; Homalodisca vitripennis). Multiple subspecies of Xf occur and are host specific. Xf subsp. fastidiosa is the causal agent of Pierce’s disease (PD). Xf subsp. multiplex and Xf subsp. sandyi are commonly found in North America but do not cause PD. Rapid diagnostics to...
