in the Dinaric karst of the western Balkans, using five grid sizes with cells of 80×80,
40×40, 20×20, 10×10, and 5×5 km. The same two hotspots could be recognized
at all scales, although details differed. Differences in sampling intensity were not sufficient
to explain these patterns. Correlations between number of species and number of
sampled localities increased with increasing cell size. Additional species are expected
to be found in the region, as indicated by jackknife 1, jackknife 2, Chao2, bootstrap,
and incidence-based coverage (ICE) species richness estimators. All estimates increased
with increasing cell size, except Chao2, with the lowest prediction at the intermediate
20×20 km cell size. Jackknife 2 and ICE gave highest estimates and jackknife 1 and
bootstrap the lowest. Jackknife 1 and bootstrap estimates changed least with cell size,
while the number of single cell species increased. In the highly endemic subterranean
fauna with many rare species, bootstrap may be most appropriate to consider. Positive
autocorrelation of species numbers was highest at 20×20 km scale, so we used this
cell size for further analyses. At this scale we added 137 localities with less positional
accuracy to 1572 previously considered, and increased 254 troglobiotic species considered
to 276. Previously discovered hotspots and their positions did not change, except for
a new species-rich cell which appeared in the south-eastern region. There are two
centres of troglobiotic species richness in the Dinaric karst. The one in the north-west
exhibited high species richness of Trechinae (Carabidae), while in the south-east, the
Leptodirinae (Cholevidae) were much more diverse. These centres of species richness
should serve as the starting point for establishing a conservation network of important
subterranean areas in Dinaric karst.10abiodiversity10aDinaric karst10aoptimal cell size10asampling intensity10ascale10asubterranean beetles1 aZagmajster, M1 aCulver, DC1 aSket, B  uhttps://cholevidae.myspecies.info/hr/node/1311303634nas a2200325   4500008004100000245010100041210006900142300001300211490000600224520273200230653002002962653001702982653001502999653001503014653001403029653001303043653001403056653001403070653001803084653001603102653001703118653001603135653001903151653002503170653001503195653001703210100001403227700001503241856005203256       2008                        eng d00aThe Leiodidae (Coleoptera) of Atlantic Canada: new records, faunal composition, and zoogeography0 aLeiodidae Coleoptera of Atlantic Canada new records faunal compo  a357-402.0 v23 aThe Leiodidae (the round fungus beetles, the small carrion beetles, and the mammal nest beetles) of Atlantic Canada (New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island) are surveyed. Twenty five species, including Colon (Colon) politum Peck and Stephan, Colon (Myloechus) forceps Hatch, Colon (Myloechus) incisum Peck and Stephan, Colon (Myloechus) schwarzi Hatch, Hydnobius arizonensis Horn, Anogdus dissimilis Blatchley, Anogdus potens (Brown), Cyrtusa subtestacea (Gyllenhal), Leiodes puncticollis (Thompson), Leiodes rufipes (Gebler), Agathidium atronitens Fall, Agathidium depressum Fall, Agathidium difforme (LeConte), Agathidium mollinum Fall, Agathidium oniscoides Palisot de Beauvois, Agathidium pulchrum LeConte, Agathidium repentinum Horn, Agathidium rusticum Fall, Gelae parile (Fall), Anisotoma blanchardi (Horn), Anisotoma discolor (Melsheimer), Anisotoma geminata (Horn), Anisotoma globososa Hatch, and Prionochaeta opaca (Say) are newly recorded in Atlantic Canada. One of these, Hydnobius arizonensis, is newly recorded in Canada. Colon (Myloechus) hubbardi Horn is newly recorded in the Maritime Provinces. Eight species are newly recorded in New Brunswick, 29 in Nova Scotia, two on Prince Edward Island, 12 on insular Newfoundland, and five in Labrador for a total of 56 new jurisdictional records. Catops paramericanus Peck and Cook and Catops simplex Say are newly recorded from mainland Nova Scotia, and records are provided to verify the occurrence of Leiodes impersonata Brown and Leiodes punctostriata Kirby in Nova Scotia, and Leptinillus validus (Horn) in insular Newfoundland. Three species, Agathidium hatchi Wheeler, Catops americanus Hatch, and Sciodrepoides watsoni (Spence), are removed from the faunal list of New Brunswick. As a result, 66 species of Leiodidae have now been recorded from Atlantic Canada. The name Anisotoma obsoleta (Horn) is revalidated while the name Anisotoma horni Wheeler is newly designated a synonym of A. obsoleta. The regional composition and zoogeography of the Leiodidae in Atlantic Canada are examined and species are grouped in six main categories, reflecting their distribution in the region. Island faunas are examined, particularly in regard to the similarities and differences of the faunas of Cape Breton Island, insular Newfoundland, and Prince Edward Island. Lone Shieling, in Cape Breton Highlands National Park, is highlighted as an apparent biodiversity 'hot spot' for this family within the region. Finally, the saproxylic component of the fauna (19 species in the Agathiidini) is briefly discussed, particularly in regard to potentially rare species, and the importance of monitoring populations of saproxylic beetles. 10aAtlantic Canada10abiodiversity10aCholevinae10aColeoptera10aColoninae10aLabrador10aLeiodidae10aLeiodinae10aNew Brunswick10anew records10aNewfoundland10aNova Scotia10aPlatypsyllinae10aPrince Edward Island10asaproxylic10azoogeography1 aMajka, G.1 aLangor, D.  uhttps://cholevidae.myspecies.info/hr/node/10461
