The male and female imago stage and a new species of the Hermanella complex are described based on material from Pará State, Northern Brazil: Hydromastodon cf. mikei (Thomas & Boutonnet, 2004) and Paramaka froehlichi sp. nov. The male imago of Hydromastodon cf. mikei can be distinguished from Hydromastodon sallesi by the following combination of characters: (1) body color pattern, especially abdominal terga translucent white with terga I to IV washed with black on posterior margin; (2) compound eyes anteriorly rounded; (3) medial projection of the styliger plate short; and (4) penis lobes close to each other and with posterolateral projection as long as ½ of its length. The male imago of Paramaka froehlichi sp.nov. can be distinguished the from the other species of the genus by the following combination of characters: (1) fore and hind wings with membrane brown; (2) legs uniformly yellowish-white, without distal band; (3) abdominal terga II to VI with marks more expanded laterally, median line absent; (4) medial projection of the styliger plate broad; (5) base of telopenis arising at distal 2/3 of penis lobe; and (6): body size of 6.1 to 7.6 mm.
