Hadzioidea of the NEP (Equator to Aleutians, Intertidal to Abyss): a Review Donald B
Hadzioidea of the NEP (Equator to Aleutians, intertidal to abyss): a review Donald B. Cadien 31 August 2005 (revised 11Oct 2007) Introduction to the Hadzioidea The superfamily was originally constituted as the Melitoidea (Bousfield 1977). This concept was critiqued by J. L. Barnard and Karaman (1980), and in response Bousfield renamed the group Hadzioidea without changing its composition (Bousfield 1983). Only three families are included in this superfamily, although one of them (Hadziidae) is further divided into three unofficial groups – weckeliids, hadziids, and nuuanids. These were originally included in the broad concept of the gammaroids, but have been separated for several decades. The taxonomic position suggested by Bousfield (2001)is used here, but Barnard and Karaman and others retained them as several groups within the gammaroids s. l.. The discussion of the hadzioids in J. L. Barnard & C. M. Barnard (1983, pp. 137-140, and as “Melita Group” pp. 147-151) may help show how members of this superfamily differ from other gammaroids, and from each other. The first family in the superfamily, the Allocrangonyctidae is confined to freshwater and is not covered here. The remaining two, Hadziidae and Melitidae, are primarily marine, and are both represented in the NEP. Maera sp an undescribed species from Guana Island (Photo Yale Peabody Museum) Diagnosis of the Hadzioidea – “body not carinate nor rostrate, toothed on abdomen only (rarely on peraeon): urosome dorsal spine groups weak or lacking; sexual dimorphism strongly expressed in body size and in gnathopods, and in antenna 2 and peraeopods; antennae 2 lacking calceoli; antennae strongly developed, 1 usually much the longer, peduncular segment 2 elongate; accessory flagellum prominent (occasionally very reduced or lacking); inferior antennal sinus small or sharply incised; eye (when present) basically small, rounded, occasionally reniform.

LOWRY & R.T. SPRINGTHORPE Crustacea section, Australian Museum, 6 College Street, Sydney, New South Wales, 2010, Australia. ([email protected]; [email protected]) * In: Lowry, J.K. & Myers, A.A. (Eds) (2009) Benthic Amphipoda (Crustacea: Peracarida) of the Great Barrier Reef, Australia. Zootaxa, 2260, 1–930. Abstract In the Melita group, new records of Dulichiella pacifica Lowry & Springthorpe are reported from the Great Barrier Reef. The record of Dulichiella australis (Haswell) from the GBR is rejected. The genus Melita (M. myersi G. Karaman and M. sampsonae sp. nov.) is reported from the GBR for the first time. The genus Tegano Barnard & Karaman is amended and reported from Australian (T. atkinsae sp. nov.), New Caledonian (T. levis (Stock & Iliffe)) and Japanese (T. shiodamari (Yamato)) waters for the first time. Key words: Crustacea, Amphipoda, Melitidae, Melita group, Great Barrier Reef, Australia, taxonomy, new species, Dulichiella pacifica, Melita sampsonae, Melita myersi, Tegano atkinsae Introduction The recent description of the Maeridae Krapp-Schickel, 2008 excluded 40 genera from the Melitidae (Krapp- Schickel 2008; Lowry & Hughes 2009). This still leaves about 45 genera in four or five groups within the Melitidae (sensu lato). The Melita group of 22 genera is mainly characterised by: a laterally compressed body; small, dorsal robust setae on urosomite 2; a basofacial seta on the peduncle of uropod 1; a scale-like inner ramus; and elongate outer ramus on uropod 3 which is 1– or 2–articulate, with article 2, when present, short or long, never greatly elongate.

Zoosystema 31 (1) : 17-32. ABSTRACT A new species of the stygobiont melitid amphipod genus Pseudoniphargus Chevreux, 1901 is described from an anchialine cave located on the inner shore of the Salses-Leucate coastal lagoon, on the French Mediterranean coast. Th e new species is distinguished from other members of the genus by the combined display of: 1) gnathopod II not sexually dimorphic, with short carpus; 2) outline of basis of pereopods V-VII sexually dimorphic, with both margins convex and with overhanging posterodistal lobe in male, whereas margins subparallel and posterodistal lobe present but not overhanging in female; 3) uropod I protopod KEY WORDS lacking basofacial robust seta; 4) protopod of uropod III sexually dimorphic, Crustacea, proportionaly more elongated in male; 5) exopod of male uropod III not Amphipoda, Gammaridea, strongly elongated (less than 12 times as long as wide), slightly upcurved and Melitidae, tapering; female exopod similar but shorter (about 8.8 times as long as wide); stygofauna, and 6) telson wider than long, with distal margin shallowly excavated and with France, mixohaline waters, two distal robust setae at each side. Th e relationships of this species are brieﬂ y new species.

First Observations on the Phylogeny of the Families Gammaridae
J N H, 2003, 37, 20, 2461–2486 First observations on the phylogeny of the families Gammaridae, Crangonyctidae, Melitidae, Niphargidae, Megaluropidae and Oedicerotidae (Amphipoda, Crustacea), using small subunit rDNA gene sequences ULRIKE ENGLISCH†‡, CHARLES OLIVER COLEMAN‡ and JOHANN WOLFGANG WA¨ GELE‡ †Lehrstuhl fu¨r Spezielle Zoologie, Ruhr-Universita¨t Bochum, 44780 Bochum, Germany; e-mail: [email protected] ‡Humboldt-Universita¨t zu Belrin, Museum fu¨r Naturkunde, Institut fu¨r Systematische Zoologie, 10099 Berlin, Germany (Accepted 21 February 2002) This study examines amphipod phylogeny based on small subunit (18S) rDNA sequence data. Complete sequences of 25 species representing six families were used to test the phylogenetic information content of this gene for reconstruction of amphipod phylogeny. The alignment proved to be informative for most of the studied taxa. The monophyly of the families Gammaridae, Crangonyctidae, Niphargidae and Oedicerotidae is supported. The Melitidae are not monophyletic in the reconstructed topologies, but weak molecular evidence for the monophyly of this group could be observed in spectra of supporting positions. A close relationship of Gammaridae+Melitidae or Gammaridae+Crangonyctidae is not supported, rather there are supporting positions for the incompatible sister-group relationship (Gammaridae+Niphargidae) and (Crangonyctidae+Niphargidae). The molecular evidence is in favour of the latter relationship. The evolution of cephalothoracic apodemes is discussed in the light of other phylogenetic hypotheses resulting from molecular data. K: rDNA, Crustacea, Amphipoda, molecular phylogeny, parsimony, maximum likelihood, Physid. Introduction During the last decade considerable advances concerning the taxonomy of amphi- pods have been achieved (Barnard and Karaman, 1991). Nevertheless, the phylogen- etic position of the major amphipod taxa is controversial.

Comments on the Newly Proposed Gammaridean Amphipod Families Crangonycidae and Melitidae
COMMENTS ON THE NEWLY PROPOSED GAMMARIDEAN AMPHIPOD FAMILIES CRANGONYCIDAE AND MELITIDAE BY JOHN R. HOLSINGER Department of Biology, Old Dominion University, Norfolk, Virginia 23508, U.S.A. Bousfield (1973), in his recent book entitled "Shallow-water Gammaridean Amphipoda of New England", has elevated the Crangonyx group to the family Crangonycidae and the melitids to the family Melitidae. The division of the heterogeneous and widely distributed family Gammaridae into separate families that more clearly reflect evolutionary phylogenies and delineate natural groups is certainly justified. However, in view of the many unresolved taxonomic and zoo- geography problems within the Gammaridae and especially within the generic clusters making up the crangonycids and the melitids, the erection of the new families Crangonycidae and Melitidae seems to me to be premature. The three or four of us (M. Straškraba and myself in particular) who are currently working on genera and species in the Crangonyx group on a world-wide basis have still failed to reach agreement on precisely how to define this group, much less elevate it to familial level. Moreover, the taxonomic status of the melitids (roughly equivalent to the Hadzia group; see Holsinger & Minckley, 1 97 1 ) is also in a state of flux. In my opinion, the most acceptable approach to the subdivision of Gammaridae would be to treat newly established families on a cosmopolitan basis, considering all potential genera, their morphological affinities, distributional patterns, etc., inste4d of choosing only a few examples from a narrowly defined geographical region and basing whole new taxa on them. The elevation of the Crangonyx group, an exclusively freshwater group of amphipods, to the familial level seems out of place in a guidebook devoted almost entirely to marine and brackish water amphipods of the New England region.
