So far, the sole confirmed host record for the Brazilian species is Solierella minarum Ducke, 1907 attacked by Holopyga wagnerella du Buysson, 1904 ( Rocha-Filho et al. 2019 ). Holopyga is readily distinguished from other Elampini genera based on the following combination of characters: scapal basin transversely cross-ridged; genal carina present; Rs&M 2 v abruptly bent medially and diverging from M+Cu 2 v before cu-a 2 v; 1Cu 2 c and R 2 c with setae; tarsal claw with two or more subsidiary teeth (rarely with one); mesopleuron distinctly carinate and angulate; and notauli usually faintly marked.According to Kimsey & Bohart (1991) , there are six species recorded to Brazil : H. boutheryi Brèthes, 1902 , H. iheringi du Buysson, 1901 , H. luzulina Dahlbom, 1854 , H. piliventris Ducke, 1907 , H. ujkelyiana Mocsáry, 1914 , and H. wagnerella du Buysson, 1904 . Three species are found in northeastern Brazil , H. iheringi , H. piliventris , and a new species is herein described.
