A new species in the genus Coptotettix(Orthoptera: Tetrigidae: Tetriginae) from northern Thailand

Coptotettix acutiangulus Zha sp. nov. from northern Thailand is described and illustrated with photographs. Morphological differences with a similar species C. annandalei are described in detail. C. acutiangulus Zha sp. nov. may be potentially distributed in Nepal. A brief discussion of the ecology and habitat of C. acutiangulus is given.

A taxonomic reassessment of Tubeufiales based on multi-locus phylogeny and morphology

This study deals with an extensive taxonomic reevaluation focusing on phylogenetic relationships and morphological characterization of Tubeufiales,especially those helicosporous hyphomycetes which are difficult to identify.Based on evidence from DNA sequence data and morphology,we introduce 13 new genera in the family Tubeufiaceae,viz.Acanthotubeufia,Dematiohelicoma,Dematiohelicomyces,Dematiohelicosporum,Dematiotubeufia,Helicoarctatus,Heli-cohyalinum,Helicotruncatum,Neochlamydotubeufia,Neohelicoma,Pleurohelicosporium,Pseudohelicomyces and Pseu-dohelicoon;transfer Chaetosphaerulina from Dothideomycetes genera incertae sedis,and Artocarpomyces and Helicodochium from Ascomycetes genera incertae sedis into Tubeufiaceae;introduce 52 new species,viz.Berkleasmium fusiforme,B.longisporum,Chlamydotubeufia cylindrica,Dematiohelicosporum guttulatum,Helicoarctatus aquaticus,Helicodochium aquaticum,Helicohyalinum infundibulum,Helicoma aquaticum,H.brunneisporum,H.cocois,H.rufum,H.fusiforme,H.longisporum,H.multiseptatum,H.rubriappendiculatum,H.septoconstrictum,H.tectonae,Helicomyces hyalosporus,Helicosporium aquaticum,H.flavisporum,H.setiferum,H.vesicarium,H.viridiflavum,Neochlamydo-tubeufia fusiformis,Neohelicomyces hyalosporus,Neohelicosporium acrogenisporum,N.astrictum,N.ellipsoideum,N.irregulare,N.krabiense,N.laxisporum,N.ovoideum,Pleurohelicosporium parvisporum,Pseudohelicomyces aquaticus,P.hyalosporus,Tubeufia abundata,T.bambusicola,T.brevis,T.brunnea,T.chlamydospora,T.dictyospora,T.eccentrica,T.fangchengensis,T.hechiensis,T.inaequalis,T.krabiensis,T.rubra,T.sessilis,T.sympodihylospora,T.sympodilaxispora,T.taiwanensis and T.tratensis;provide 43 new combinations,viz.Acanthohelicospora guianensis,Acanthotubeufia filiforme,Berkleasmium aquatica,B.guangxiense,B.latisporum,B.thailandicum,Dematiohelicoma perelegans,D.pulchrum,Dematiohelicomyces helicosporus,Dematiotubeufia chiangraiensis,Helicohyalinum aquaticum,Helicoma eli-norae,H.gigasporum,H.hongkongense,H.linderi,H.nematosporum,H.pannosum,H.serpentinum,Helicomyces chiayiensis,Helicotruncatum palmigenum,Neochlamydotubeufia khunkornensis,Neohelicoma fagacearum,Neoheli-comyces pallidus,Neohelicosporium abuense,N.aurantiellum,N.griseum,N.morganii,N.myrtacearum,N.nizam-abadense,N.sympodiophorum,N.taiwanense,N.vesiculiferum,Pseudohelicomyces indicus,P.paludosus,P.talbotii,Pseudohelicoon gigantisporum,P.subglobosum,Tubeufia dentophora,T.geniculata,T.lilliputea,T.machaerinae,T.sympodiophora and T.xylophila;introduce 16 new records,viz.Dictyospora thailandica,Helicomyces colligatus,H.torquatus,Neohelicosporium guangxiense,N.hyalosporum,N.parvisporum,Thaxteriellopsis lignicola,Tubeufia aquatica,T.chiangmaiensis,T.cylindrothecia,T.filiformis,T.guangxiensis,T.laxispora,T.parvispora,T.roseohelicospora and T.ectonae.The taxonomy of Helicoma,Helicomyces and Helicosporium is revisited based on phylogenetic analyses and morphological evidence.Neorhamphoria is transferred to Bezerromycetaceae.Three species are excluded from the genus Chlamydotubeufia,twelve species from Helicoma,four species from Helicomyces,25 species from Helicosporium,six species from Neoacanthostigma and one species from Tubeufia.A multi-gene phylogenetic tree based on maximum likelihood and Bayesian analyses of ITS,LSU,RPB2 and TEF1a sequence data of species of Tubeufiales is provided.Detailed descriptions and illustrations are provided,as well as the morphological comparison with similar taxa are explored.The checklist of accepted Tubeufiales species and re-organised Tubeufiales species are provided.
