Taxonomic and phylogenetic characterizations reveal four new species of Simplicillium (Cordycipitaceae, Hypocreales) from Guizhou, China
Simplicillium species are commonly found from soil, seawater, rock surface, decayed wood, air and as symbiotic, endophytic, entomopathogenic and mycoparasitic fungi. Minority insect-associated species was reported. Simplicillium coccinellidae , S. hymenopterorum , S. neolepidopterorum and S. scaraba...

Summary: | Simplicillium
species are commonly found from soil, seawater, rock surface, decayed wood, air and as symbiotic, endophytic, entomopathogenic and mycoparasitic fungi. Minority insect-associated species was reported.
Simplicillium coccinellidae
,
S. hymenopterorum
,
S. neolepidopterorum
and
S. scarabaeoidea
were introduced as the newly insect-associated species. The phylogenetic analyses of two combined datasets (
LSU
+
RPB1
+
TEF
and
SSU
+
ITS
+
LSU
) revealed that
S. coccinellidae
and
S. hymenopterorum
were both nested in an independent clade.
S. neolepidopterorum
and
S. scarabaeoidea
have a close relationship with
S. formicidae
and
S. lepidopterorum
, respectively.
S. neolepidopterorum
can be easily distinguished from
S. formicidae
by ellipsoidal to cylindrical, solitary conidia which occasionally gather in short imbricate chains.
S. scarabaeoidea
could be easily distinguished from
S. lepodopterorum
by having longer phialides and larger conidia. Based on the morphological and phylogenetic conclusion, we determine the four newly generated isolates as new species of
Simplicillium
and a new combination is proposed in the genus
Leptobacillium
