  A new species of the mygalomorph spider genus Euagrus Ausserer (Araneae: Euagridae) from central Mexico and new records of E. gus Coyle from Tlaxcala Abstract  A new species of the spider genus Euagrus Ausserer, 1875 from temperate pine-oak forests in the states of Tlaxcala and Hidalgo, Mexico is described: E. pulque sp. nov. The description of the new species is based on male and female adult specimens. Additionally, Euagrus gus Coyle, 1988 is recorded for the very first time in the state of Tlaxcala.

Three’s a Crowd: On the Taxonomic Status of Three Species of Macrothele Ausserer, 1871, Described from Africa by Pierre L. G. Benoit (Araneae: Macrothelidae)

Abstract and figures
The three macrothelid species described by the late P. L. G. Benoit at the Royal Museum for Central Africa are digitised and re-evaluated: Macrothele abrupta Benoit, 1965 and Macrothele incisa Benoit, 1965 are declared nomina dubia as the name bearing types of both taxa are juvenile. Macrothele triangularis Benoit, 1965 is a valid species and we depict and describe its spermathecae for the first time.
