Material examined. 15 females—Cuba, north of Matanzas Province , on Ataenius terminalis (Chevrolat) ( Coleoptera : Scarabaeidae ). FIGURES 1–7. DIC micrographs of Asca quinquesetosa , female. 1, idiosoma in dorsal view; 2, idiosoma in ventral view; 3, sternal and genital shields; 4, opisthonotal region of idisoma; 5, podonotal region of idiosoma; 6, epistome; 7, tubercle at the posterior edge of the opisthonotal shield. FIGURES 8–11. DIC micrographs of Macrocheles merdarius , female. 8, idiosoma in dorsal view; 9, idiosoma in ventral view; 10, sternal shield; 11, genital and anal shields. Remarks. Macrocheles merdarius is a common cosmopolitan species that has been collected from many species of dung beetles around the world. It is easily recognised by its small size, the simple and needle-like dorsal shield setae ( Figure 8 ), except J5 slightly pilose, genu IV with six setae, anterior section of sternal shield with linea arcuata connected by transverse lines ( Figure 10 ), and ventral shields ornamented with very faint sculptural pattern and punctations ( Figure 11 ).
