Orthotylini
Genus Guides
43Orthotylini is a large tribe of plant bugs ( Miridae) comprising more than 230 described and over 540 described . Members of this tribe are distributed globally, with notable radiations in Australia associated with specific plants including Callitroid conifers and woody shrubs. The tribe is taxonomically complex, with ongoing research revealing extensive undescribed diversity and challenging previous classifications of relationships within Orthotylinae.

Similar Taxa
- AustromiriniPreviously considered distinct; phylogenetic analysis shows Lattinova complex (formerly Austromirini) is sister-group to Palassocoris complex within Orthotylini, rendering Orthotylini without reclassification
More Details
Taxonomic Complexity
The tribe exhibits extensive undescribed diversity, particularly in Australia. The Palassocoris complex, characterized by elongate , represents a monophyletic suprageneric group whose recognition has classificatory implications for tribal boundaries.
Phylogenetic Uncertainty
Relationships within Orthotylinae remain under study. The finding that Palassocoris complex is sister to Lattinova complex (formerly Austromirini) challenges the monophyly of Orthotylini as traditionally circumscribed.
