Temporary deleterious mass mutations relate to originations of cockroach families
TLDR
Wing deformity and principal, family rank origination rates correlate from the Mississippian/Pennsylvanian to the present, which is the first significant support for the association of detrimental mutations and evolution on the geological scale.
Paleocene origin of the cockroach families Blaberidae and Corydiidae: Evidence from Amur River region of Russia.
Morphna paleo sp. n., the earliest winged representative of any living cockroach genus and the earliest representative of the family Blaberidae, is described from the Danian Arkhara-Boguchan coal
New genus and species of cavernicolous cockroach (Blattaria, Nocticolidae) from Vietnam.
TLDR
Histone 3 DNA-based maximum likelihood analyses indicate a recent origin and close phylogenetic relationship between Nocticola spp. and Helmablatta sp.-consistent with the Quaternary age of the source lava tubes.
Cockroaches Probably Cleaned Up after Dinosaurs
TLDR
Smaller particles were broken down biochemically in the cockroach hind gut, which indicates that the recent lignin-decomposing termite and cockroach endosymbionts might have been transferred to the cockroaches' gut upon feeding on dinosaur feces.
Afro-Asian cockroach from Chiapas amber and the lost Tertiary American entomofauna
TLDR
The present species is the first significant evidence for incomplete hiati between well defined cockroach genera — a result of the extensive fossil record of the group.
Native Ectobius (Blattaria: Ectobiidae) from the Early Eocene Green River Formation of Colorado and Its Reintroduction to North America 49 Million Years Later
TLDR
This species indicates a cosmopolitan distribution of the genus during the mid Paleogene, and supports its current relict distribution in modern north-temperate and African ecosystems.
New species of Macrophyllodromia (Blattaria, Blattellidae) from Ecuador and a key to males of the genus.
TLDR
One new species of the cockroach genus Macrophyllodromia is described, including one new species described here, that is divided into 3 species groups--splendida, amabile and maximiliani.
Description of Helicoconis tatricus sp. n. (Neuroptera, Coniopterygidae) from Slovakia (Central Europe) and key for determination of all Palaearctic species of subgenus Helicoconis.
TLDR
A new species of dustywings is described from the foothills of the Tatra Mountains in Slovakia and differs from other species of the subgenus Helicoconis by structure of male genitalia-unfurcated styli and wide and short apophyses.
Two new troglobitic cockroach species of the genus Spelaeoblatta (Blattaria: Nocticolidae) from North Thailand
TLDR
Two new troglobitic cockroach species Spelaeoblatta myugei and S. thailandica n.
