Placing Palpigradi: Phylotranscriptomics reveals venom homologs in the smallest order of arachnids

we sampled a population of the cave-inhabiting species Eukoenenia spelaea from Slovakia, produced a high-quality transcriptome, and inferred its placement using a dense phylogenomic matrix of 1083 loci, drawn from high-quality transcriptomic libraries and complete genomes. this first palpigrade transcriptome revealed the presence of several venom peptide orthologs known from spider, tick, pseudoscorpion and scorpion venom gland transcriptomes.
