03EF87EBFFE9FFCD7F938D27FBA3FA9F.taxon	etymology	Etymology. The species name is a homage to Dr. Joachim Ulrich Adis (in memoriam) for steadily supplying material from the Amazon.	en	Grangeiro, Daniela C., Souza, Leila A., Christoffersen, Martin L. (2017): New species of Xiphoniscus and new record of Androdeloscia escalonai (Isopoda, Scutocoxifera, Oniscidea, Philosciidae) from Brazilian Amazon. Zootaxa 4350 (2), DOI: 10.11646/zootaxa.4350.2.11
03EF87EBFFE9FFCD7F938D27FBA3FA9F.taxon	discussion	Remarks. Xiphoniscus mirabilis and X. adisi sp. nov. strongly resemble each other in the shape of endopod of pleopod 1 of the male (in both species the distal portion of the endopod is turned outwards and has spines) and in coxal plate 2 of the male, which is elongate, shaped like a spine in both species. The coxal plate shaped like a spine is an autapomorphy of Xiphoniscus. Xiphoniscus adisi sp. nov. differs from X. mirabilis in: 1) Coxal plate prolonged, reaching posterior edge of pereonite III and overlapping it (Fig. 1 A, B), versus reaches the medial part of pereonite IV, extending parallel to its lateral edge in X. mirabilis, although the illustration provided by Leistikow (2000 b) shows the prolongation of coxal plate reaching the posterior edge of pereonite 3 only. 2) Six ommatidia (Fig. 1 A), versus 7 − 8 in X. mirabilis. 3) First antenna with 2 + 5 aesthetascs (Fig. 1 C), versus 2 + 6 in X. mirabilis. 4) Molar process of the mandible with 5 penicils: 1 + 4 (Fig. 2 A, B), versus 4: 1 + 3 in X. mirabilis. 5) Lateral endite of first maxilla with 4 + 5 teeth (Fig. 2 E), versus 4 + 4 in X. mirabilis. 6) Second maxilla without trichiform setae or pectinate scales on lateral lobe, and with group of 6 long setae on medial lobe (Fig. 2 D), versus with trichiform setae and pectinate scales on lateral lobe, and without long setae on medial lobe in X. mirabilis. 7) Maxilliped endite with one tooth near the laterodistal edge; a knob-like penicil on rostral surface was not seen (Fig. 2 C) versus endite with two teeth caudally and knob-like penicil rostrally in X. mirabilis. 8) Endopod of male pleopod 1 with apex truncate (Fig. 3 A), versus apex acute in X. mirabilis. 9) Three teeth in the apex of pleopod 1 endopod, versus four teeth in X. mirabilis. 10) The position of noduli laterales (Fig. 6).	en	Grangeiro, Daniela C., Souza, Leila A., Christoffersen, Martin L.
