Achradocera
Achradocera is a genus of long-legged flies (Dolichopodidae: Diaphorinae) distributed across the Americas and Polynesia. The genus was restored from subgenus status in 1975 and currently comprises 12 recognized species. Phylogenetic analysis identifies two species groups: the Nearctic barbata group and the Neotropical femoralis group. Biogeographic studies indicate vicariance as the primary driver of speciation in this genus.
Pycnomerini
Pycnomerini is a tribe of beetles in the family Zopheridae, subfamily Zopherinae, first described by Erichson in 1845. The tribe includes the genus Pycnomerus, whose members are primarily saproxylic, inhabiting dead and decaying wood in forest ecosystems. Some species, such as P. rimatara and P. prebblei from Rimatara in French Polynesia, are known only from subfossil material and are considered likely extinct due to habitat destruction. The tribe has a global distribution with documented observations across multiple regions.
