GENUS NEOECHINISCOIDES MØBJERG, JØRGENSEN & KRISTENSEN GEN. NOV . (FIGS 2–7) urn:lsid:zoobank.org:act:8FA86B31-39B9-4523- AFAF-E0DB7DE91562: Diagnosis : Primarily interstitial Echiniscoidinae, with seven to eight, occasionally six or nine, anisonych claws (generally more than six claws on each leg in adults). Epicuticular pillars absent. The dorsal cuticle is strongly sculptured. Cirri Aand Eare present and relatively short in both sexes. First and second leg sensory structures are small and dome shaped. The third leg sensory structure is a seta, and the fourth leg sensory structure is papillar, as is the primary clava. Secondary clavae (cephalic papilla) are more distinct and appear relatively larger in males than in females. Cephalic papillae may be subdivided into secondary and tertiary clavae. Seminal receptacles are lacking. The anal system appears large, with two wings associated with the lateral lobes. The distance between the anus and the gonopore is larger in females than in males. Asmall ventral cuticular plate is present in front of the female gonopore (not observed in N. pollocki ). Etymology : From the Greek νέος, neos (new or young) combined with the generic name Echiniscoides . Type species: Neoechiniscoides aski described below. Other members of the genus: Neoechiniscoides horningi (Miller & Kristensen, 1999) comb. nov. (basionym: Echinsicoides horningi Miller & Kristensen, 1999), sub-Antarctic (Macquarie Island), collected from the lichen Caloplaca sp. on rock in lower supralittoral zone. Neoechiniscoides pollocki (Hallas & Kristensen, 1982) comb. nov. (basionym: Echiniscoides pollocki Hallas & Kristensen, 1982), Rhode Island, USA, found interstitially, from tidal sediments. Differential diagnosis of the genus: Neoechiniscoides leg sense organs are of the Echiniscoides sigismundi type, i.e. p1 and p2 are dome shaped, p3 is a short setae, and p4 is similar to the primary clava, consisting of a small papilla with a spiny tip. Cirri (internal, external, Aand E) are shorter in ...
