Aphanius pluristriatus (Jenkins, 1910) (Cyprinodontidae) is a poorly known species from Fasa, located in the Mond Riverdrainage system, east of Shiraz, southern Iran. It has not been investigated since its first description, its validity has beenquestioned and a synonymy with A. sophiae (Heckel, 1849) has been suggested. In this study, we describe a new collectionof Aphanius specimens from the Zarjan spring system, which is probably the same spring system from where Jenkins(1910) collected the type specimens of A. pluristriatus. The morphological characters of our new series of specimens areconsistent with those of A. pluristriatus as originally described by Jenkins (1910). We emend the original description ofA. pluristriatus and add morphometric and meristic data. A comparison with the related taxa A. sophiae, A. farsicus (for-mer A. persicus) and A. isfahanensis reveals that A. pluristriatus can be separated from them by a smaller caudal peduncleindex, higher number of flank bars, lower number of gill rakers, and higher J scale index. Therefore A. pluristriatus rep-resents a valid species, which is at present restricted to the drainage system of the Mond River. We suggest that A. pluris-triatus originated from an ancient A. sophiae population in the Kor River Basin during the Quaternary. At that time, theKor River was draining to the Persian Gulf by the “Paleo-Kor River” and the Mond River. During the Late Quaternary orHolocene, the connection between the Kor River and the Persian Gulf has been blocked as a result of tectonic uplift (theKor River Basin is endorheic today). Thus, A. pluristriatus most likely is the relict of an ancient Aphanius population from the Quaternary “Paleo-Kor River” drainage system.

The infauna of Chabahar Bay (Iranian Coast of the Gulf of Oman) was investigated using shallow water (less than 10 m) grab-samples between June 2013 and March 2014. The magelonid fauna of these samples was studied and prioritized, with four species being present:M. fauchaldisp. nov.,M. symmetrica, M.cf.cinctaandM. crenulifrons. The new species differs from all known magelonid species within the Persian Gulf region in possessing polydentate abdominal hooks. A fifth species, currently undescribed, was also found. The validity ofM. pulchellaoriginally described from Kuwait is discussed in light of its closeness toM. crenulifrons. The main distinguishing feature between the two species is the presence or absence of crenulation of the anterior prostomial margin, a character shown to be variable inM. crenulifrons. Although differences between the type specimens of both species suggestsM. pulchellato be a valid species, examination of further material and DNA analysis is needed.

In a survey on the edaphic mesostigmatic mites in mangrove forests of Qeshm Island, eastern of the Persian Gulf, two species of the family Ascidae were collected in broken cockleshells and sand in littoral zone: Leioseius sepidehae sp. nov. and Protogamasellus mica (Athias-Henriot, 1961). This is the first record of the genus Leioseius from Iran. Leioseius sepidehae sp. nov. is described from adult females. Intraspecific variations of some characters of P. mica are discussed, and based on those, P. primitivus machadoi Genis, Loots & Ryke, 1967 and P. primitivus similis Genis, Loots & Ryke, 1967 are herein synonymized under P. mica. Finally, the occasional presence of the gland pores gv1 in Ascidae is reviewed, and a key to the Iranian genera and species of Ascidae is presented.

We review species of Parodon Valenciennes, 1850 from the Magdalena, Cauca, Orinoco, Amazonas, Atrato and Caribbean-Guajira River basins of Colombia using meristic and morphological characters. We recognize eight valid species, five previously described: P. apolinari Myers, from the Orinoco River basin; P. buckleyi Boulenger and P. pongoensis (Allen) from the upper Amazon; P. caliensis Boulenger, from the upper Cauca River drainage; and P. suborbitalis Valenciennes, from Lake Maracaibo basin. Three new species are described: P. alfonsoi, from the lower Magdalena River drainage; P. magdalenensis, from the middle Magdalena and upper Cauca River drainages; and P. atratoensis, from the Atrato River basin. We redescribe Parodon suborbitalis using type specimens and topotypes, and designate lectotypes. A taxonomic key is included for identification of the species, as well as geographic distribution maps.

The most enigmatic problems with the nearly 200 salt domes pierced in the Persian Gulf and in the Zagros Mountain Ranges (ZMR) in southern Iran, a unique morphology in the world, have been the matter of this study, which is based on a combination of field work, enhancement of satellite and aerial photographs etc. In the ZMR, structural anomalies are frequently associated with similar facies distribution patterns. In the eastern portion of the region, emergent salt plugs of Infra-Cambrian age exhibit the same alignment patterns. Such trends bear no apparent genetic relationship to the Tertiary folding responsible for the present Zagros fold belt, but rather indicate their affinity with linear basement features which are readily observable on Land sat imagery and aerial photographs. Bending of anticlines in the competent cover rock, combined with minor strike-slip faults and horizontal displacements of parts of folded structures, strongly point to the presence of these basement faults. The salt plugs, which have pierced cover rocks of up to 10000 m thick, are distributed on the Arabian Platform along regional basement faults. The area of diapir outcrops is bounded by the Oman Line to the east and by the Kazerun fault to the west. Pieces of the basement have been brought up to the surface on some of the salt domes. The fragments were transported by rotational ascent of the Hormuz Salt Formation to the present and former land surfaces. The recognition of features related to basement tectonics and realization of their implication in the control and modification of geological processes are important adjuncts to the search for hydrocarbon accumulations in this region. To our best knowledge, data of basement faults in the study area are scarce. Therefore, this study was carried out to determine basement faults and their relation to salt dome distribution. Considering the fold axes bending, the trend of the salt plugs and also the distribution of epicenters of the last century, n umerous new basement faults are introduced in this paper.
