Key characters

Head largely yellow, mesonotum greyish-black, scutellum entirely dark, femora yellow. Wing length 1.3-2.0 mm. Third antennal segment distinctly angulate, with distinct point at upper corner.  Aedeagus with distiphallus enlarged. Detailed descriptions of external morphology, host plants and both male and female terminalia were given by Shiao et al. (1991) and Shiao (2004).


Spencer (1973) re-examined Liriomyza cepae and split the species into three. Liriomyza cepae s. str. is the "Oggersheim strain" of Nietzke (1943, 1953) and is less widespread in Europe and occurs later in the season than L. nietzkei Spencer which is the "Herxheim race" of Nietzke (1943, 1953). Spencer (1973) also raised the east Asian chinensis ssp. to species level. Spencer (1973) considered that these Allium -feeding species most probaby arose in east Asia. All three species have a characteristic angulate third antennal segment and dark thorax. Spencer (1973, 1989) lists some differences in external morphology:  L. cepae and L. chinensis both have a black scutellum but L. nietzkei has a partially yellow scutellum; L. cepae has largely dark coxae and femora, whereas L. chinensis has bright yellow coxae and femora.  However, these species are more reliably distinguished by examination of male genitalia (Dempewolf 2004). In recent years, L. chinensis has become an important pest of Allium spp. in SE Asia (Tran et al. 2007) including Vietnam (Andersen et al. 2002) and Indonesia (Rauf et al. 2000). Although restricted to Allium spp., there is anecdotal evidence in Indonesia that the puparia can lodge in the skins of the onion bulbs and so could be transported between regions relatively easily (Aunu Rauf personal communication).
