Diagnosis. Wing length 1.8–2.0 mm.

Aedeagus (Fig. 30 and 31 in Lonsdale 2017): basiphallus slightly sclerotized with membranous extension distally; mesophallus fused to distiphallus, forming two tubules fused basally, enlarged distally; cerci with an elongated seta at apex.

Comments. Liriomyza blechi   is morphologically similar to Liriomyza marginalis (Malloch)   and Liriomyza sorosis (Williston)   . It is differentiated from L. sorosis   by the seta pattern on the cercus and from L. marginalis   by the shape of the aedeagus. Spencer (1990) considers the possibility that this species is a leaf miner of several families within the Asteridae clade, such as Boraginaceae   , Verbenaceae   , Plantaginaceae   , and Loganiaceae   . This information has been partially confirmed by Carvalho-Filho et al. (2016), who identified some specimens of L. blechi   reared from Spigelia anthelmia   L., and by Eiseman and Lonsdale (2018), who listed specimens reared from Plantago virginica L.  

The present study records for the first time L. blechi   forming mines on leaves of Gentianaceae   and showing differentiated shapes of mines between the different plant families. Mines in Poaceae   species are linear with frass widely spaced, although mines in Dicliptera sericea   and Spigelia anthelmia   are similar to L. blechi   mines. The mesonotum bands of specimens reared from Dicliptera   and Spigelia   usually are dark brown (Fig. 26 and 27), but specimens collected in Poaceae   usually present the central area of mesonotum are predominantly paler, almost orange (Fig. 28), similar to description of L. marginalis   . However, the shape of aedeagus resemble which illustrated by Eiseman & Lonsdale (2018) to L. blechi   .
