Subfamily Apomastinae Bond & Hedin subfam. n.

Type genus.

Note.

Defined as a euctenizid subfamily comprising the genera Myrmekiaphila , Apomastus , and Aptostichus in Bond et al. (2012b), the new designation, despite considerable phylogenetic support was dismissed as a nomen nudum in an online catalog (Platnick 2012) due to the absence of a formal diagnosis. To correct this oversight, I formally diagnose below the newsubfamily Apomastinae and again provide a list of included genera. As was originally intended, authorship is to be attributed to Bond and Hedin.

Diagnosis.

Apomastinae , a lineage defined in extensive phylogenetic analyses that include multiple lines of evidence that comprises genes and morphology ( Bond and Hedin 2006; Bond et al. 2012b) can be morphologically distinguished from all other euctenizids by having a patch of endite cuspules that is restricted to the proximal inner margin (Fig. 38; rather than being uniformly distributed across the endite face, see Stockman and Bond 2008, fig. 10) and by having two distinct posterior median spinneret spigot types (as opposed to a single type, Stockman and Bond 2008, fig. 24).

Included genera.

Myrmekiaphila Atkinson, 1886

Aptostichus Simon, 1891

Apomastus Bond and Opell, 2002
