The notes on the occurrence of Longidorus poessneckensis Altherr, 1974 (Nematoda: Dorylaimida) in the Slovak Republic

Abstract

264 SummaryThe record of occurrence of Longidorus poessneckensis Altherr, 1974 in forest soils with Betuleto-CarpinetoQuercetum in geographically specific conditions of a hilltop contributes to the broadening of ecological knowledge about this species. To date, the species was considered to prefer the habitats along river banks -narrow or large valleys and plains. The ecological, morphometrical and molecular characteristics of recorded L. poessneckensis are presented here.

Longidorus poessneckensis Altherr, 1974 and L. piceicola Lišková, Robbins & Brown, 1997 (Nematoda: Longidoridae): new records from Poland and the first description of the L. poessneckensis male and a bivulval female

“…The identification codes of the polytomous key published by Chen et al (1997), based on the present data and other sources (Lišková & Sturhan, 2000; Sturhan & Loof, 2001; Tiefenbrunner & Tiefenbrunner, 2004; Kumari et al, 2009; Lišková & Kumari, 2010), are: A56 B1234 C34 D3 E4 F345 G12 H1 I12.…”

“…Longidorus poessneckensis , in addition to its type-locality in Germany (Altherr, 1974 ), has been reported from several other localities in Germany (Sturhan & Loof, 2001 ), Slovakia (e.g. Lišková & Sturhan, 2000 ; Lišková & Kumari, 2010 ), Austria (Tiefenbrunner & Tiefenbrunner, 2004 ) and the Czech Republic (Kumari et al, 2009 ).…”

Description of Longidorus cholevae sp. n. (Nematoda, Dorylaimida) from a riparian habitat in the Rila Mountains, Bulgaria

“…It differs from all these species except for Longidorus caespiticola and Longidorus pseudoelongatus , by the more anteriorly situated guide ring (ave. 32.6 (30–37) vs ave. 40 (36–43) μm in Longidorus poessneckensis ; 37–48 μm in Longidorus macrosoma ; 37.5–48 μm in Longidorus helveticus ; 42–47 μm in Longidorus carniolensis ; 38 μm in Longidorus macroteromucronatus and ave. 38.7 (35–41) μm in Longidorus pius ). Among the above group the new species appears most similar to Longidorus poessneckensis from which itdiffers by adult specimens having different shape of amphidial pouches (almost as long as wide vs visbly longer than wide), males abundant vs males rare and different tail shape in first stage juveniles (elongate conoid with narowly tapering terminus vs elongate conoid with blunly rounded terminus) (Sturhan and Loof 2001, Kumari et al 2009, Lišková and Kumari 2010, Kornobis and Peneva 2011). Further, it can be differentiated from:…”

“…All these are large species, very similar in their morphology having long odontostyles, elongated or short not bilobed pouch-like amphidial fovea, continuous head region, short bluntly conoid to almost hemisphaercial tail, mainly amphimictic (only with Longidorus macrosoma and Longidorus poessneckensis males are rare). Longidorus caespiticola and Longidorus macrososma occur mainly in western Europe including the British Isles, Longidorus poessneckensis was reported from central (Germany, Slovakia and Czech Republik) and northern Europe (Poland); the first two species were found in association with a wide range of crops and forest trees (Brown and Boag 1975, Boag and Brown 1975); Longidorus poessneckensis with preference toflood plains and hill deciduos forest habitat (Lišková and Kumari 2010) and Longidorus helveticus associated with deciduous forest and orchard threes in central Europe (Lamberti et al 2001, Širca and Urek 2009, Kumari and Subbotin 2012). Longidorus carniolensis is known only from Slovenia (grapevine) and Longidorus cholevae sp.…”
