Biology and host plant in the Brazilian Amazon . The mines of Liriomyza blechi in leaves of Blechum pyramidatum (Acanthaceae) ( Fig. 18 ) are similar to those previously presented by Spencer & Stegmaier (1973) and Spencer et al . (1992). In addition, this species produces a light green linear mine in the distal portion of leaves of Spigelia anthelmia (Loganiaceae) ( Fig. 19 ) that posteriorly becomes brown after the larva exits the mine. Distribution . Guadeloupe, Dominican Republic, Martinique, U.S.A (Florida, Texas), Brazil (Pará). Material examined. BRAZIL, Pará, 4 males, 3 females, and 5 undetermined, Belém, house garden, 01°25.51′03ʺS 48°27.11′64ʺW, ex. Blechum pyramidatum , 20.I.2006, F.S. Carvalho-Filho [coll.]; 1 male with same data, except 20.III.2014, ex. Spigelia anthelmia . All deposited in MPEG. Remarks. This is the first record of this species in mainland South America. The specimens analyzed fit the description and illustrations provided by Spencer & Stegmaier (1973). This species shares with Liriomyza marginalis (Malloch) and Liriomyza sorosis (Williston) a surstylus with a sclerotized bar ( Figs. 16, 17 ). However, Liriomyza blechi differs from L. sorosis in having cercus with one long apical seta ( Figs. 16, 17 ) (six in L. sorosis ), and from L. marginalis in the shape of the distiphallus. In addition, L. marginalis is associated with grasses ( Paspalum : Poaceae ) and L. blechi with species of Loganiaceae and Acanthaceae (Spencer & Stegmaier 1973, Spencer et al . 1992). Liriomyza sorosis is associated with both grasses and dicots (Stegmaier 1967).
