Lomamyia trombetensis Penny, 1983

( Figs. 1-9 )

Diagnosis. L. trombetensis ( Figs. 1-2 ) are recognized by the combination of the following morphological characteristics: a. forewing elongate, apically falcate; pterostigma reddishbrown; seven Rs longitudinal veins; five radial crossveins, one directly below pterostigma; four inner gradate crossveins and two outer gradate heavily margined forming a dark patch ( Fig. 3 ); b. hindwing with pterostigma reddish; two radial crossveins; three inner gradate crossveins and no outer gradate ( Fig. 3 ) and, c. female terminalia ( Figs. 4-8 ): eighth sternite narrow with a heavily sclerotized transverse band, broader laterally ( Fig. 6 ); eighth gonocoxite small with a medial sclerotized band ( Fig. 6 ); ninth tergite and ectoproct fused, extending ventro-anteriorly as a narrow band ( Figs. 4-5 ); ninth gonocoxites with hypocaudae long, finger like ( Fig. 7 ) and, bursa-copulatrix-spermatheca complex caudally swollen into sphere; short fertilization canal elongate and thin spermathecal duct ( Figs. 5, 8 ) ( Penny 1983; Faulkner 1992).

Geographical distribution ( Fig. 9 ): L. trombetensis was known from Pará state, its type locality, and Amazonas state, in Brazil ( Penny 1983; Faulkner 1992; Machado and Martins 2019); the new record extends its geographic distributional range about 1,700 km southeast from the type locality and about 2,000 km southeast from Amazonas state, the previous localities.
