Here we describe the new tribe, Parartocarpeae, within Moraceae (mulberry family). The tribe comprises two small Malesian genera, Parartocarpus and Hullettia, brings total number of tribes to seven. Evidence for this designation comes from a phylogeny based on 333 nuclear genes sequenced using target enrichment via hybridization (hybseq). Morphological characters that set Parartocarpeae apart other include combination following characters: lateral nonamplexicaul stipules, spirally arranged leaves without annulate stipule scars, presence single layer involucral inflorescence bracts, lack perianth tissue, wherein flowers are embedded in cavities receptacle. With tribe-level circumscription is now well-supported by phylogenetic methods. Because markers employed here work well throughout Moraceae, they can facilitate much needed at genus level family.
