摘要：

Four new species belonging to the enigmatic fossil spider family Lagonomegopidae Eskov & Wunderlich, 1995 are described from Albian Spanish amber. Two new genera are created: Spinomegops gen. nov., based on two specimens described as S. arcanus sp. nov. from alava amber (Penacerrada I outcrop, Burgos), and S. aragonensis sp. nov. from San Just amber (Teruel); and Soplaogonomegops gen. nov., represented by the type species S. unzuei sp. nov. from El Soplao amber (Cantabria). A single specimen from alava amber is tentatively assigned to Lagonomegops Eskov & Wunderlich, 1995 and described as L.? cor sp. nov. We confirm the existence of previously contentious numerous tarsal and metatarsal trichobothria on Burlagonomegops alavensis Penney, 2005, and reinterpret the mouthpart morphology of Grandoculus chemahawinensis Penney, 2004. In light of our new data, the family diagnosis for Lagonomegopidae is emended and the family Grandoculidae Penney, 2011 is synonymized with Lagonomegopidae.
