Abstract

A new fossil of the colletid bee subfamily Xeromelissinae is described and figured from Miocene amber of the Dominican Republic. The species is represented by a single female and is proposed as Chilicola electrodominica sp. n. The fossil is distinguished from living Chilicola as well as the only other fossil xeromelissine, C. gracilis. The relative ages of the genus Chilicola, the subfamily, and the Colletidae as a whole are briefly discussed.

Sambia succinica gen. et sp.n. from Eocene Baltic amber is described and illustrated. It is apparently the first amber fossil that can be definitively assigned to Tenthredininae. It displays two diagnostic forewing characters for this subfamily: having a bend distally in vein R and the junctions of veins M and Rs + M with vein R being some distance from each other. The variance and possible transitions between the anal vein configurations among the genera in Tenthredininae is briefly discussed.

Abstract

Rhadinolabis phoenicica Engel, Ortega-Blanco & Azar gen. et sp.n. is described and figured from two female earwigs preserved in Early Cretaceous amber from Lebanon, representing the oldest Dermaptera in amber. In addition a partial nymph is recorded from the same deposits. The placement of the genus among Neodermaptera is briefly discussed.
