ZooKeys 942: 1–19. https://doi.org/10.3897/zookeys.942.50399 Abstract A new species, Hyalella tepehuana sp. nov., is described from Durango state, Mexico, a region where stud- ies on Hyalella have been few. This species differs from most species of the North and South American genus Hyalella in the number of setae on the inner plate of maxilla 1 and maxilla 2, characters it shares with Hyalella faxoni Stebbing, 1903. Nevertheless, H. faxoni, from the Volcan Barva in Costa Rica, lacks a dorsal process on pereionites 1 and 2. Also, this new species differs from other described Hyalella species in Mex- ico by the shape of the palp on maxilla 1, the number of setae on the uropods, and the shape of the telson. -

Guide to Crustacea
38 Guide to Crustacea. This is a very large and varied group, comprising numerous families which are grouped under six Sub-orders. In the Sub-order ASELLOTA the uropods are slender ; the basal segments of the legs are not coalesced with the body as in most other Isopoda ; the first pair of abdominal limbs are generally fused, in the female, to form an operculum, or cover for the remaining pairs. This group includes Asellus aquaticus, which is FIG. 23. Bathynomus giganteus, about one-half natural size. (From Lankester's "Treatise on Zoology," after Milne-Edwards and Bouvier.) [Table-case No. 6.] common everywhere in ponds and ditches in this country, and a very large number of marine species, mostly of small size. The Sub-order PHKEATOICIDEA includes a small number of very peculiar species found in fresh water in Australia and New Zealand. In these the body is flattened from side to side, and Peraca rida—Isopoda. 39 the animals in other respects have a superficial resemblance to Amphipoda. In the Sub-order FLABELLIFERA the terminal limbs of the abdomen (uropods) are spread out in a fan-like manner on each side of the telson. Many species of this group, belonging to the family Cymothoidae, are blood-sucking parasites of fish, and some of them are remarkable for being hermaphrodite (like the Cirri- pedia), each animal being at first a male and afterwards a female. Mo' of these parasites are found adhering to the surface of the body, behind the fins or under the gill-covers of the fish. A few, however, become internal parasites like the Artystone trysibia exhibited in this case, which has burrowed into the body of a Brazilian freshwater fish. -
Additions to and Revisions of the Amphipod (Crustacea: Amphipoda) Fauna of South Africa, with a List of Currently Known Species from the Region
Additions to and revisions of the amphipod (Crustacea: Amphipoda) fauna of South Africa, with a list of currently known species from the region Rebecca Milne Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa & Charles L. Griffiths* Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa E-mail: [email protected] (with 13 figures) Received 25 June 2013. Accepted 23 August 2013 Three species of marine Amphipoda, Peramphithoe africana, Varohios serratus and Ceradocus isimangaliso, are described as new to science and an additional 13 species are recorded from South Africa for the first time. Twelve of these new records originate from collecting expeditions to Sodwana Bay in northern KwaZulu-Natal, while one is an introduced species newly recorded from Simon’s Town Harbour. In addition, we collate all additions and revisions to the regional amphipod fauna that have taken place since the last major monographs of each group and produce a comprehensive, updated faunal list for the region. A total of 483 amphipod species are currently recognized from continental South Africa and its Exclusive Economic Zone . Of these, 35 are restricted to freshwater habitats, seven are terrestrial forms, and the remainder either marine or estuarine. The fauna includes 117 members of the suborder Corophiidea, 260 of the suborder Gammaridea, 105 of the suborder Hyperiidea and a single described representative of the suborder Ingolfiellidea. -

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.
