摘要

Female specimens of Porrhomma present particular problems of identification not only for the beginner, but in some cases for experienced arachnologists as well and it can certainly be considered a critical genus in our fauna. With the exception of twospecies (P. errans and P. egeria), which may be distinguished from other British members of the genus by details of their leg spination, all species require detailed and critical examination of the epigynes. As in many spiders, the external appearance of the epigyne in ventral view can be quite variable, particularly in the appearance of the internal structures seen through the cuticle, and care needs to be taken with isolated females for this reason. While most species can be reliably distinguished bycareful examination of the epigyne in ventral view, there are a number of closely similar species pairs for which it is often advisable to dissect out and clear the epigyne so that it can be mounted on a slide and studied in dorsal view. Wherever possible, specimens should be compared with material in a reference collection which has been either identified or confirmed by an experienced arachnologist.
