Anyphaena (Banks, 1896)

Rivera-Quiroz, F. Andrés & Álvarez-Padilla, Fernando, 2023, Integration or minimalism: twenty-one new species of ghost spiders (Anyphaenidae: Anyphaena) from Mexico, European Journal of Taxonomy 865, pp. 1-94 : 19

Pacifica group

Diagnosis

The pacifica group can be separated from other species groups of Anyphaena by the following characters.

Males

Both of the species described here show modifications in the venter of coxae II, III and IV ( Figs 12E– F , 15E–F ). Coxae II show a small and relatively inconspicuous bump. Coxae III and IV have fully developed ventral spurs. The palp of the pacifica group shows a morphology similar to that of the pectorosa and porta groups. It can be separated from both by the large dorsal cymbium bulge, and the larger RTA posterior branch that projects dorso-laterally ( Figs 11A, C–D , 14A, C–D ).

Females

Both new species differ from other Anyphaena by having an enlarged epigynal plate bulging anteriorly ( Figs 10F , 13F ). This enlarged plate shows two sclerotized spots that might serve as an anchor point for male palp structures; the spermathecae are usually oval to spherical ( Figs 11E–F , 12G–H , 14E–F , 15G–H ).
