“…The data for L. hyrcanus b’ and stylet length were slightly lower when compared with L. belgradiensis . Conversely, L. belgradiensis post‐uterine sac length was higher than that of L. hyrcanus (Miraeiz et al., ; Oro, ). These differences can be explained by intra‐specific variability, presence/absence of gravid females, and a slight shrinking of the nematode body during preparation for light microscopy observations.…”

Summary Laimaphelenchus belgradiensis and L. hyrcanus species, both recently described, were morphologically, morphometrically and molecularly compared based on original descriptions, including photomicrographs and drawings. Although L. belgradiensis males were not found, all female morphological and morphometric characters are comparable for the two Laimaphelenchus species. The shape and structure of the tail tip, currently considered to be one of the most important morphological character used for differentiation within the genus, does not differ between L. belgradiensis and L. hyrcanus: four pedunculated tubercles in a square position, ending in 9‐10/10‐12 finger‐like protrusions. Additionally, the D2‐D3 expansion segments of the large subunit of ribosomal RNA were also very similar, with only three differences in alignment. Thus, this study proposes the taxonomic status of L. belgradiensis as a junior synonym of L. hyrcanus.

Laimaphelenchus vrste su veoma sitne nematode, tako da se neki delovi njihovog tela mere nanometrima. Morfologija bazirana na anatomskim karakteristikama i merenjima pomoću optičkog mikroskopa je u prošlosti bila jedini način identifikacije i klasifikacije ovih organizama. U današnje vreme ovaj pristup je dopunjen nano-morfologijom uz pomoć scanning elektronske mikroskopije, kada se otkrivaju nepoznati morfološki detalji koji olakšavaju rad taksonomima. Nova vrsta roda Laimaphelenchus je skoro opisana. Laimaphelenchus belgradiensis je otkriven na crnom boru sa simptomima sličnim onima koje izaziva Bursaphelenchus xylophilus. Iako obe vrste pripadaju istoj familiji i slične su u morfološkom pogledu, ženke obe vrste poseduju vulvalni poklopac, i spikuli mužjaka su slični, one poseduju i značajne razlike. Osnovna morfološka karakteristika koja ih razlikuje je prisustvo pomoćnih organa na repu -tuberkula sa prstolikim proširenjima vidljivih samo uz pomoć scanning elektronskog mikroskopa. Uloga ovih tvorevina je u radu objašn-jena i ključ za vrste je dat u ovom radu.Ključne reči: Laimaphelenchus belgradiensis, nano-morfologija, tuberkule, prstolika proširenja REZIME UVOD Nematode roda Laimaphelenchus su veoma sitni organizmi. Neki delovi njihovog tela se mere nanometrima, tako da je identifikacija i klasifikacija ovakvih organizama kompleksan zadatak.U prošlosti, glavni izvor identifikacije i klasifikacije je bila morfologija koja se zasnivala na anatomskim karakteristikama i merenjima. Danas, ovaj pristup se dopunjava "nano-morfologijom" koja se bazira na scanning elektronskoj mikroskopiji (SEM) i molekularnim podacima i filogeniji. Laimaphelenchus belgradiensis je skoro opisana vrsta (Oro, 2015). Ova nematoda je pronađena u Beogradu, na crnom boru (Pinus nigra Arnold) sa simptomima sličnim uvenuću borova koje izaziva karantinska vrsta Bursaphelenchus xylophilus Steiner & Buhrer, 1934 (Nickle, 1981.Iako obe vrste pripadaju istoj familiji i slične su u morfološkom pogledu, one poseduju i značajne razlike. Bursaphelenchus xylophilus je rasprostranjen u Aziji gde izaziva najveće štete i severnoj Americi, ali ga u Australiji nema ili se javlja sporadično kao u Africi. Ova karantinska vrsta je u Evropi utvđena samo u Portugaliji i Španiji (EPPO, 2013). Vrste roda Laimaphelenchus su kosmopolitske i prisutne su na svim kontinentima, uključujući i Antarktik (Peneva and Chipev, 1999). Mnoge Bursaphelenchus vrste su u prirodnoj asocijaciji sa insektima koji mogu biti njihovi vektori (poput Monochamus spp.) a nematode se mogu naći u sprovodnim sudovima četinara, dok su Laimaphelenchus vrste povezane sa mahovinama, lišajima i sličnim habitatima i nalaze se na kori, uglavnom bora. Ženke obe vrste poseduju vulvalni poklopac, osobinu koja nije karakteristična za druge Aphelenhide a i spikuli mužjaka su slični. Osnovna morfološka karakteristika koja ih razlikuje je prisustvo pomoćnih organa na repu -tuberkula sa prstolikim proširenji-ma (projekcijama) kod roda Laimaphelenchus.

Laimaphelenchus suberensis sp. nov. obtained from declining Quercus suber trees of Herdade da Gouveia de Baixo, Alentejo, Portugal, is described and illustrated based on morphological, biometrical and molecular characters. The diagnosis of Laimaphelenchus species has been commonly based on the presence or absence of a vulval flap and on the shape structure of the tail tip. The species described here has been included in the Laimaphelenchus group without vulval flap, and can be distinguished from morphologically similar species by its tail tip shape structure that has a stalk-like terminus and three diffuse tubercles with 4-6 finger-like protrusions. For the molecular analyses, the mitochondrial DNA region from the cytochrome oxidase subunit I (mtCOI), the D2-D3 expansion segments of the large subunit (LSU) and small subunit (SSU) of rRNA gene were amplified and sequenced. Sequences of L. suberensis sp. nov. clustered separately from all Laimaphelenchus spp. with available sequences in Genbank, confirming its identification as a new species. This is the second report of the genus Laimaphelenchus in Portugal, associated with Q. suber: L. heidelbergi and L. suberensis sp. nov. Keywords Cytochrome oxidase subunit I. Cork oak.
