A new species of the Clausidium Kossmann, 1874 copepods is described, illustrated and provided by Confocal Laser Scanning Microscope photo on the basis of specimens from the gill chamber of Callianidea typa H. Milne Edwards, 1837 from the Iranian coast of the Persian Gulf. Clausidium persiaensis sp. nov is unique in the possession of a fi ne spine on endopod-1 of the antennae, large blade-like setae with an acute tip on P1, and the shape of P5 and the anal somite. Th e new species extends the… 
A new species of Clausidium Kossmann, 1874 (Copepoda: Cyclopoida) associated with ghost shrimps from the Persian Gulf, including female-male interlocking mechanisms and remarks on host specificity
A new clausidiid copepod was found associated with the ghost shrimp Neocallichirus jousseaumei (Nobili) in the Persian Gulf and Structures of taxonomic importance that exhibit complex shapes were scanned to generate 3-D prints that gave valuable insights about female/male interlocking mechanisms.
New geographic records of Harpacticoida (Crustacea: Copepoda) from the Persian Gulf and the Gulf of Oman, Iran
The meiobenthic harpacticoids of the Persian Gulf and the Gulf of Oman has been almost unknown. During October 2014 to September 2016, interstitial and phytal harpacticoids were collected from tide
First record of ghost shrimp Corallianassa coutierei (Nobili, 1904) (Decapoda: Axiidea: Callichiridae) from Indian waters
A comprehensive checklist of the infraorder Axiidea is prepared based on previous records from Indian waters and a Callichiridae ghost shrimp species Corallianassa coutierei is recorded and described here for the first time from the Indian waters.
Nauplius-The Journal of The Brazilian Crustacean Society
Analysis of mitochondrial DNA gene sequences (CO1) demonstrates that two major clades, with strong support, can be identified within the Clausidium copepods in the southern waters of Iran, representing distinct taxonomic entities at the species rank.
Host specificity and microhabitat preference of symbiotic copepods (Cyclopoida: Clausiididae) associated with ghost shrimps (Decapoda: Callichiridae, Callianideidae)
The results revealed that both species of symbiotic copepod demonstrated extremely high host specificity, and within a single host shrimp species, each symbiont species displayed strong spatial patterns in microhabitat selection on their hosts’ bodies.
Population differentiation in the Persian Gulf and Gulf of Oman: insights from the ghost shrimp's associated copepods, Clausidium iranensis and Clausidium persiaensis
The results obtained demonstrate the existence of two genetically and geographically distinct clades, corresponding to the Persian Gulf and Gulf of Oman populations, and indicate high diversity, population expansion and high connectivity among populations of C. persiaensis and C. iranensis.
A review on the state of the biodiversity knowledge on Iran’s southern seas: introducing a methodology to evaluate the validity of the reported cases
High maritime activities in the Persian Gulf and the Gulf of Oman as the major waterways for oil and gas transport and the lack of a documented database on total taxa diversity require greater


First record of Clausidium (Copepoda, Clausidiidae) from Brazil: a new species associated with ghost shrimps Neocallichirus grandimana (Gibbes, 1850) (Decapoda, Callianassidae)
A new clausidiid copepod found living in galleries of ghost shrimps Neocallichirus grandimana in Natal, Brazil represents the first record of the genus in Brazil and can be easily distinguished from its congeners by the unique characteristics observed.
Two New Species of Clausidiidae (Copepoda, Poecilostomatoida) from Korea
Two new species of Clausidiidae, each belonging to the genus Clausidium Kossmann, 1875 and Hippomolgus G. O. Sars, 1917, are described from Korea, the first record on the genera Clausidium and Hippo-gus in the West Pacific.
Two new semi-parasitic copepods from the Peruvian coast
150 semi-parasites sent to the United States National Museum from Salaverry are found to be new species belonging to two genera of cyclopid copepods and are here described and figured.
Host selection of the symbiotic copepod Clausidium dissimile in two sympatric populations of ghost shrimp
Investigation of factors that affect the density of C. dissimile in the field and in the laboratory supported observations from the field in that C. Dissimile significantly preferred S. trilobata over L. louisianensis, but unlike the field data, copepods did not appear to prefer female over male hosts when size was held constant.
Littoral mud shrimps (Decapoda: Gebiidea & Axiidea) of the Persian Gulf and Gulf of Oman, Iran
The mud shrimps of Iran are not well known. Material for the present study was collected from 21 out of 51 intertidal localities from the Persian Gulf and Gulf of Oman, Iran. In total, 11 species

Ten orders of the subclass Copepoda were cladistically analyzed using 21 morphological characters and found that four orders containing species symbiotic with aquatic animals are monophyletic in a fully resolved cladogram.
Copepod phylogeny: a reconsideration of Huys & Boxshall's ‘parsimony versus homology’

  • 2004
A hypothesis of copepod phylogeny proposed by Huys & Boxshall (1991) was reanalyzed by using TOPOLOGY and DELTRAN options to remove many character reversals and the resulting tree is two steps longer than the best fit tree obtained strictly by using parsimony criterion and optimizd with the same procedure.
Assessment of Congo red as a fluorescence marker for the exoskeleton of small crustaceans and the cuticle of polychaetes
The Congo red staining turned out to be rather efficient and yielded intensively fluorescing structures, which made a very detailed visualization of the external morphology of small crustaceans and polychaetes by confocal laser scanning microscopy possible.
