Diagnosis. The Hybobathus arx  species group belongs to the genus Hybobathus  stat. rev. (see above). Species of the H. arx  group have three vittae of golden microtrichia that are joined together by a circular microtrichose area posteriorly. They are larger (11–18 mm) and have a distinctly petiolate abdomen, with a narrow 2nd abdominal segment and distinctly widened 3rd and 4th segments ( Miranda et al. 2016; Miranda 2017). The H. arx  species group might be confused with the Pelecinobaccha summa  species group (see below) due to some superficial similarities between the scutum and abdominal markings, but they can be distinguished, among other characters, by the single row of pile on the dorsal occiput of the H. arx  group (the P. summa  species group has two rows of pile) ( Miranda 2017).

Biology. Hybobathus arx ( Fluke, 1936)  has been reared as predators of Antianthe expansa Germar  ( Hemiptera  : Membracidae  ) ( Montoya & Pérez 2009). Hybobathus luciane  Miranda, 2017 was recorded preying on Membracis foliata (Linnaeus)  ( Hemiptera  : Membracidae  ), H. phaeopterus ( Schiner, 1868)  on Guayaquila xiphias (Fabricius)  ( Hemiptera  : Membracidae  ), and H. persimilis (Curran, 1930)  on Tuthillia cognata Hodkinson, Brown & Burckhardt  ( Hemiptera  : Psyllidae  ) ( Pérez & Iannacone 2009; Miranda 2017).
