Anomopterellidae restored, with two new genera and its phylogeny in Evanioidea (Hymenoptera). [PDF]

open access: yesPLoS ONE, 2013
BackgroundAnomopterellidae was originally classified as a family within the Evanioidea, and later lowered to a subfamily, Anomopterellinae, of Praeaulacidae. Up to date, only Rasnitsyn 1975, with four species, was assigned to Anomopterellinae.

A targeted gene phylogenetic framework to investigate diversification in the highly diverse yet geographically restricted red devil spiders (Araneae, Dysderidae)

open access: yesCladistics, Volume 40, Issue 6, Page 577-597, December 2024.
ABSTRACT The family Dysderidae is a highly diverse group of nocturnal ground‐dwelling and active‐hunter spiders. Dysderids are mostly restricted to the Western Palearctic, and particularly rich and abundant around the Mediterranean region. Interestingly, the distribution of species richness among its 24 genera and three subfamilies is highly biased—80%

Paleopteran molecular clock: Time drift and recent acceleration

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
Constant evolution rates, which form the foundation of the strict molecular clock model, do not apply in the case of Paleoptera, highlighting a notable bias in the molecular clock hypothesis. The current biodiversity may be the outcome of a relatively recent, exponential increase in base substitution rates.

An edible fruit from the Jurassic of China

open access: yesChina Geology, 2020
: Frugivory is an important ecological tie between animals and angiosperms. It plays an important role in the evolution of food webs and energy flow networks in the ecosystem. However, little is known about how old this relationship can be due to lack of
