. The dentition is extremely variable (Table 3). The supraoral lamina bears usually two unicuspid lateral teeth separated by a toothless bridge. In two cases, one or both lateral teeth were bicuspid. The infraoral lamina bears 7–11 teeth, usually unicuspid. In two cases, a bicuspid tooth was present. There are usually three endolateral teeth on each side of the oral disc (85% of counts), but four teeth also occur (15%). The most common endolateral formula is 2–2– 2, but in three cases a unicuspid and in two cases a tricuspid tooth occurred.

A). Two specimens possessed what we term accessory cusps inside the ring formed by the supraoral and infraoral laminae and the left and right endolaterals. One specimen had an accessory unicuspid tooth placed at the level of the third left endolateral and the other two unicuspid teeth, one on each side below the supraoral lamina. The velar apparatus possessed 2–5 very small tentacles, with a central tentacle present in two cases and absent in three. There were no tubercles or wings.

up-listed the status to Critically Endangered according to the following IUCN (2001) criteria: B1ab(i,ii,iii,iv,v) + 2ab(i,ii,iii,iv,v). The situation is even more critical when one considers the two species individually. Water regulation, habitat alteration and pollution are the main threats. In the Loúros River drainage specifically, irrigation canals and draining ditches, often with cement-lined sides and bottom, coupled with water-level fluctuations, have resulted in reduced habitat for ammocoetes as well as reduced spawning areas for adults (

The new species name is an adjective formed from the noun Graeci, a tribe of Hellenes living since Prehistoric times in the area where the lamprey occurs. The Graeci were early on in contact with the inhabitants of the Italian Peninsula, mainly Latins, who then referred to all of the Hellenes as Greeks.
