Description of two new Cryptaphelenchus species from China and Japan

Summary The study aims to provide the morphological and molecular characterisation of two newly discovered Cryptaphelenchus species, namely: C. curvatum n. sp. tumidus Morphologically both species are minute nematodes, possess medium-sized stylets with basal knobs laterally directed, short post-uterine sacs (PUS). was detected from local Pinus branch samples is characterised by having an equal proportion adult males females, body lengths females 353 (320-388) μ m 277 (256-293) m, lateral fields four lines, 8-10 long stylet, PUS about one vulva width conical posterior end a blunt pointed tip. in packaging wood sample Japan rare male, 236 (217-270) 180 obscure fields, stylet 6.8 (6.0-7.5) half slim finely rounded phylogenetic trees were also constructed based on rRNA gene sequences (D2-D3 segments 28S, ITS 18S) discussed detail. Since offer multitrophic relationships among their insect vectors associated microbiota, recognition studies recovered populations will facilitate researchers determine whether these might play any ecological roles bionomics or residing host tree.
