New Lineaburmops fossils (Araneae: Lagonomegopidae) with contrasting color patterns from mid-Cretaceous Kachin amber, northern Myanmar

Abstract

The fossil spider family Lagonomegopidae is widespread in the Cretaceous period, and mainly reported from mid-Cretaceous Kachin amber, northern Myanmar. Here, two new lagonomegopid species, belonging to the genus Lineaburmops, are described from Kachin amber: Lineaburmops longiantepes sp. nov. and Lineaburmops rhombus sp. nov., which showing similar contrasting body coloration as other Lineaburmops species. The compositional element of these special color patterns and their potential functions are discussed.
