We describe two new species of Leydigia Kurz, 1875 (Chydoridae, Cladocera) from Spain. L. (Neoleydigia) iberica sp. nov. has a series of traits rarely observed in well-studied species of the subgenus L. (Neoleydigia), and never in this combination: (1) PP distance large; (2) numerous, low hillocks on preanal margin of postabdomen; (3) numerous setae in lateral fascicles on postabdomen, plus distalmost and next setae subequal in size; (4) sensory seta shifted to distal end of antenna I, but not so markedly as in L. microps; (5) fully setulated basal segment of distalmost scraper on limb III; (6) 5 setae on exopodite III. L (N.) korovchinskyi sp. nov. has seven setae on limb III exopodite, characteristic for only two species of the subgenus L. (Neoleydigia) Kotov, 2009, namely L. (N.) propinqua and L. (N.) microps, but the former differs from both latter taxa in: (1) absence of a “coarse” striation; (2) rounded apex of labral keel and (3) longer setae 34 of exopodite III. At this moment, each species was found in a single locality. Both species are rare and seem endemic of Iberian Peninsula (but may be found in some surrounded Mediterranean territories); they could be regarded as relicts sensu Korovchinsky (2006).

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Two new species of Sphaeromopsis (Sphaeromatidae: Isopoda) from Iran are described based on light and electronmicroscope study: Sphaeromopsis sarii sp. nov. from the coasts of Kish and Qeshm Islands, and S. persikolpos sp. nov. from Kish Island, Qeshm Islands and the southern coasts of Iran. The two species are sympatric in most areas. Sphaeromopsis sarii is distinct among other species in the genus for having a pleotelson with a faint dorsomedial furrow and a broadly rounded apex. Sphaeromopsis persikolpos sp. nov. is unique for the single suture at either side of the posterior margin of the pleon, a narrow pleotelsonic apex, and the uropodal exopod extensions that reach well beyond the pleotelsonic apex.

Six species of Eutardigrada are recorded from Portugal; four of them, Macrobiotus crenulatus Richters, 1904, Hypsibius seychellensis Pilato, Binda & Lisi, 2006, Diphascon (Diphascon) pingue (Marcus, 1936) and D. (Diphascon) patanei Binda & Pilato, 1971 are recorded for the first time in Portugal. Two species, Minibiotus orthofasciatus sp. nov. and Bertolanius (new name of Amphibolus) portucalensis sp. nov. are new to science. Minibiotus orthofasciatus sp. nov. is one of the species of the genus with three macroplacoids, microplacoid and cuticular pores forming transverse bands. The new species differs from all existing species by one or more of the following characters: distribution of the pores, shape of the pores, absence of dots on the legs, level of insertion of the stylet supports on the buccal tube. To the new species is attributed an unembryonated egg similar to those of Minibiotus intermedius (Plate, 1888), M. poricinctus Claxton, 1998, M. floriparus Claxton, 1998, and M. weglarskae Michalczyk, Kaczmarek & Claxton, 2005 but different from them in some details. Bertolanius portucalensis sp. nov. is very similar to the other species of the genus, but it differs from them in having very small cuticular tubercles. From some of them it differs by characters of the buccopharyngeal apparatus and/or of the eggs. This is the first record of the genus and of the Eohypsibiidae family in the Iberian Peninsula.

Two new species of the genus Geocharis Ehlers, 1883 (Carabidae: Trechinae, Anillini) are described (Geocharis barcorabelo n. sp. and Geocharis antheroi n. sp.) from the northern region of Portugal (Iberian Peninsula). This work provides diagnostic characters for these species and, in particular, for the structure of male genitalia. The affinities with other known species namely their putative closest relatives, as well as ecological and biogeographical comments are also included. A key for the identification of the males of the Geocharis species found north of the Tejo River in Portugal is also provided. New chorologist data on other endogean carabids from Portugal are also included.

We describe two new species: Gianius navarroi n. sp. (Phallodrilinae) and Isochaetides gianii n. sp. (Tubificinae), which were discovered during investigations on the groundwater oligochaete fauna in northern Spain. The present study contributes to the knowledge of the stygobiont oligochaete species in the Iberian Peninsula, which includes 21 species so far. Mature specimens of Lophochaeta ignota Štolc, 1886 were also collected at some sites, and are used to supplement the limited description of the reproductive organs known for the species to date. Taxonomy of the genus Lophochaeta Štolc, 1886 is discussed.

A re-assessment of spionid specimens collected from coasts around the Iberian Peninsula and initially assigned to Dispio uncinata Hartman, 1951 and Prionospio multibranchiata Berkeley, 1927 resulted in the recognition of two new species from the genera Dispio and Prionospio: Dispio glandulosa sp. nov. and Prionospio (Minuspio) sanmartini sp. nov. In addition, the examination of specimens collected near the type locality of P. multibranchiata led to a re-description of this species. The specimens examined do not correspond to the material collected from the Iberian Peninsula and it is unlikely that P. multibranchiata is found in northern European waters.

Two new species of Polyalthia from Peninsular Thailand, Polyalthia heliopetala and P. taweensis, are described and illustrated. Polyalthia heliopetala most closely resembles P. oblonga and P. motleyana. Polyalthia taweensis most closely resembles P. obliqua. Polyalthia pumila is newly reported for Thailand from a single locality; the species was previously known only from two localities in Peninsular Malaysia and has not been re-collected in over 100 years.
