DIPLOGYNIIDAE Trägårdh, 1941

Diplogyniidae species have been found on hosts belonging to Blattodea, Coleoptera ( Curculionidae , Histeridae , Passalidae , Scarabaeidae , Tenebrionidae ), Dermaptera, Hymenoptera, Isoptera, Myriapoda and Squamata ( Kazemi et al. 2008). Of the 40 Diplogyniidae genera, only 38 species belonging to 19 genera were found, on 26 species of Passalidae belonging to 11 genera; and 7 diplogyniid species were found on unidentified Passalidae ( Pearse et al. 1936; Trägårdh 1950; Womersley 1958a; Hyatt 1964; Elsen 1975, 1981; Hunter 1993a, 1993b; WiŚniewski and Hirschmann 1993a; Karg 1997; Villegas-Guzmán et al. 2008; Seeman 2012; Barrios-Torres and Villegas-Guzmán 2015; Sun et al. 2024). As many as 17 species were collected from only one host, while four species of hosts yielded only Pseudodiplogyniopsis garba (Pangella, 1906) . Each of 24 host species had only one species of Diplogyniidae .

The hosts with the most species of Diplogyniidae are Pentalobus barbatus (Fabricius, 1801) (9) and P. palini (Percheron, 1844) (4). Only Diplogyniidae were found on three species of Passalidae : Bilongicauda microseta Elsen, 1981 on Didimus aloysiisabaudiae (Pangella, 1906) , Schizodiplogynium capillatum Trägårdh, 1950 on Episphenus moorei Kaup, 1871 , and Burgeonium megabasis Elsen, 1981 on Pentalobus simia Kuwert, 1898 ( Tables 2–6 and 8).
