Egyptian Interstitial Copepoda Harpacticoida With the Description of Two New Species and One New Subspecies

Abstract

Nine species of Copepoda Harpacticoida were found in sandy beaches in Egypt during the period November 1994 to December 1996. Two species of the family Ectinosomatidae are new to science, Arenosetella bassantae n. sp. and Noodtiella toukae n. sp. The genus Noodtiella is new to the fauna of the Mediterranean Sea. One subspecies of the family Paramesochridae is new to science, Kliopsyllus constrictus egyptus n. subsp. The other species found are already known from the Mediterranean: Arenopontia nesaie (Cylindropsyllidae), Phyllopodopsyllus pauli (Tetragonicipitidae), Amphiascus parvus (Diosaccidae) and Nitocra spinipes (Ameiridae). The last two species (A. parvus and N. spinipes) have already been recorded from Egyptian waters. This paper contains descriptions of the two new species and of local variations in one of the known species, Arenopontia nesaie and the new subspecies Kliopsyllus constrictus egyptus. Two more species could as yet not be identi ed beyond generic level: Alteutha sp. (family Peltidiidae), and Amphiascus sp. RÉSUMÉNeuf espèces de copépodes harpacticoïdes on été trouvées dans les plages sableuses, en Égypte, durant la période de novembre 1994 à décembre 1996. Deux espèces de la famille des Ectinosomatidae sont nouvelles pour la science, Arenosetella bassantae n. sp. et Noodtiella toukae n. sp. Le genre Noodtiella est nouveau pour la faune de la mer Méditerranée. Une sous-espèce de la famille des Paramesochridae est nouvelle pour la science, Kliopsyllus constrictus egyptus n. subsp. Les autres espèces trouvées sont déjà connues de Méditerranée: Arenopontia nesaie (Cylindropsyllidae), Phyllopodopsyllus pauli (Tetragonocipitidae), Amphiascus parvus (Diosaccidae) and Nitocra spinipes (Ameiridae). Les deux dernières espèces (A. parvus et N. spinipes) ont déjà été citées des eaux égyp-tiennes. Cet article contient les descriptions des deux espèces nouvelles et des variations locales de l'une des espèces connues, Arenopontia nesaie, ainsi que de la nouvelle sous-espèce Kliopsyllus constrictus egyptus. Deux espèces supplémentaires n'ont pas pu être identi ées au-delà du niveau générique: Alteutha sp. (Peltidiidae) et Amphiascus sp.

“…23.9.1.1) and Alteutha has been used as a valid name in at least 25 works, published by at least 10 authors in the last 50 years (ICZN Art. 23.9.1.2) [e.g.Por 1960a;Wiborg 1964;Pallares 1968a;Fives 1969;Apostolov 1973;Gharagozlou-Van Ginneken 1976;Wells 1976Hicks 1977Hicks , 1982Hicks , 1986aCoffin 1981;McClelland 1982;Apostolov & Marinov 1988;Dahms 1992Dahms , 1993aSong & Chang 1995;Mitwally & Montagna 2001;Apostolov & Pandourski 2002;Duggan et al 2006;Kane 2007;Michels 2007;Veit-Köhler & Fuentes 2007a, 2007b.

“…23.9.1.2 are met (Peltidiidae is cited in e.g. Geddes 1968b;Wells 1970Wells , 1976Hicks 1977Hicks , 1982Hicks , 1986aHumes 1981bHumes , 1984Apostolov & Marinov 1988;Dahms 1992Dahms , 1993aMitwally & Montagna 2001;Seifried 2003Seifried , 2004Varela 2005;Suárez-Morales et al 2006;Veit-Köhler & Fuentes 2007a-b;Gheerardyn et al 2008;Ivanenko et al 2008), the junior synonym Peltidiidae is considered the valid name (nomen protectum) which has precedence over the older name Steropinae (nomen oblitum). Family Tisbidae Stebbing, 1910Philippi (1843 proposed the genus Idya Philippi, 1843 (type species by monotypy: Idya barbigera Philippi, 1843) while Lilljeborg (1853: 191) created the generic name Tisbe for Cyclops furcatus Baird, 1837 (type species by monotypy).…”

A new genus of Ectinosomatidae (Copepoda, Harpacticoida) from sublittoral sediments in Ubatuba, São Paulo State, Brazil, including an updated key to genera and notes on Noodtiella Wells, 1965

“…A similar raised pair of multidentate lamellae on the anal somite was described for two closely related species in the genus Noodtiella: N. ornamentalis Rao, 1987 andN. toukae Mitwally &Montagna, 2001. Based on this character and the apparent differences with Arenosetella, Wells and Rao (1987) suggested that N. ornamentalis may be placed in a genus separate from Noodtiella but refrained from formally naming and diagnosing it.…”

“…d Mitwally and Montagna (2001) list the formula for P2-P4 enp-2 as 221 but do not take into account the posterior surface seta; the formula is here amended to 321 e Wells and Rao's (1987) illustration of the P2 is likely to be incorrect; the distal endopod segment appears to be reversed although the spinule row marking the original subdivision is illustrated on the correct (outer) margin; given the close relationship to N. pectinata it is also conceivable that the authors overlooked the posterior surface seta on P2-P4 enp-2.…”

A new species of Arenosetella Wilson, 1932 from Turkey with notes on the genus (Copepoda, Harpacticoida, Ectinosomatidae)

“…The 3rd segment with two terminal setae." (Mitwally and Montagna 2001). As this situation does not fit with the general pattern found in the Ectinosomatidae (Seifreid 2003), the holotype was re-examined.…”
