Abstract

Gibellula penicillioides sp. nov. and G. longispora sp. nov. , two new species parasitising spiders collected in China, are illustrated and described, based on morphological features and multiloci phylogenetic analysis. The G. penicillioides sp. nov. group is sister to the G. scorpioides group, but form long penicilloid conidiophore producing enlarged fusiform conidia ((7–) 7.5–9 (–10) × 2.5–3.5 μm). G. longispora sp. nov. is sister to G. pigmentosinum , but has slender long conidia (5–7 × 1–2 μm); teleomorph and Granulomanus-synanamorphic conidiogenous cells are absent in these two species. Type specimens of G. penicillioides sp. nov. and G. longispora sp. nov. were deposited in the Anhui Agricultural University (RCEF). In addition, a key to all known species of Gibellula is illustrated.

Discussions

• Maybe Gibellula sp.? They are common pathogens of spiders in the Cordycipitaceae. There is actually a key to the different species here (though some have been described since and many more are likely [bsky, 1 points, 1 comments]
