Papiliomyces puniceum and Metarhizium lymantriidae: two new species from the Gaoligong Mountains in southwestern China

Abstract

Two new species, Papiliomyces puniceum and Metarhizium lymantriidae, collected from the Gaoligong Mountains in Baoshan City, Yunnan Province, southwestern China, were determined by both morphological character and multilocus phylogenetic analysis. P. puniceum was confirmed to be phylogenetically related to P. shibinense and P. liangshanense, while obviously separated from them to be a unique lineage. The diagnostic features of P. puniceum were its spherical conidia and puniceus stromata solitarily on the head of Hepialidae larva. M. lymantriidae was the sister species of M. dendrolimatilis, but it was supported as a single distinct lineage. It was apparently distinguished M. lymantriidae from M. dendrolimatilis by its smaller conidia and more slender phialides Moreover, the host of M. lymantriidae was the larva of tussock moth and that of M. dendrolimatilis was the larva of Dendrolimus sp..

“…Additionally, there exist significant distinctions between M. dianzhongense and other unmentioned Metarhizium species in this study, namely M. cicadinum (Höhn.) [11,15,[42][43][44][45]. The six species are mainly parasitic on Hemiptera (M. cicadinum) and Lepidoptera (M. dendrolimatilis, M. lepidopterorum, M. lymantriidae, M. putuoense, and M. rongjiangense) hosts, which distinguishes them from M. dianzhongense (Coleoptera).…”

“…In recent years, numerous new taxa have been added to the genus Metarhizium and enriched its species diversity [6][7][8][9][10][11][12][13][14]. In the most complete taxonomic treatment of Metarhizium and its related genera, Mongkolsamrit et al [11] To date, the genus Metarhizium accommodates 74 species, including 23 species in the M. anisopliae species complex and 13 species in the M. flavoviride species complex [11,[14][15][16][17][18][19][20][21][22][23].…”
