• metabolite profiles using analytical HPLC coupled with diode array detection and mass spectrometry (HPLC–DAD–MS) revealed that the production of pigmentosin B (2) was apparently specific for Gibellula sp., while the glycoasperfuran 3 was specific for C. javanica. Keywords: antibiofilm agents; natural

• them as promising candidates for alternative antibiofilm agents. We hope that our findings will also help to raise the general scientific interest in invertebrate-pathogenic fungi, and in particular in the taxonomy and secondary metabolism of the spider pathogens.
