Figs 22, 33, 46, Map 50 Type material. Holotype male: "Brasstown Bald, GA, Union Co., 11.VIII.63', El. 2750', B" / "Rhododendron and softwood debris" / "H.R. Steeves, Jr., J.D. Patrick Jr. collectors" / "H.R. Steeves Jr. Collection" / "PARATYPE [not]" / " P. patricki [nom. nud.]"; DNA Extract MSC-2410; deposited in FMNH. Paratypes (13): 2 males, 1 female same data as type, deposited in FMNH, CUAC; 3 males and 3 females, same locality but collected September 8, 1963 from 'forest floor debris' , deposited in FMNH; 2 males and 1 female, same locality but collected May 31, 1964 from 'forest floor debris nr. dead wood' , deposited in FMNH; 1 female, same locality but collected October 23, 1965 from 'forest floor debris nr rotten wood' , deposited in FMNH. Diagnosis. This species is externally indistinguishable from P. enigma except in the following male characters: metaventral process broader and more prominent, obviously dentate in lateral view, apically rounded in posterior view, metaventrite very weakly flattened to subconcave behind; metatrochanteral process similar to that of P. enigma , with a rather narrow, recurved subapical tooth. Aedeagus with sides distinctly sinuate, wide near apex, thence apically converging, apex shallowly emarginate; apicodorsal ridges not extending to distal corners; internal sac with lateral clusters of ~8 narrow spines. Female pygidium broad, very weakly convex, without median ridge or tooth; apical ventrite with very broadly and weakly bilobed transverse median carina, concave behind. Neck weakly flattened beneath, but not carinate. TL 1.72-1.92mm; Max. width (EW) 0.59-0.69mm. Distribution. This species is known from several collections on Brasstown Bald, Georgia's highest peak (though not apparently near its peak, at a stated 2750 feet on all labels). Remarks. The distinctive internal sac armature of the aedeagus distinguishes this species from all others with fully-eyed males, and may suggest relationships to P. myersae and P. minima , which also have internal sac armature, though our phylogenetic analyses of morphological data do not unite such a group. Despite the attempted extraction of DNA from one older specimen, we have not been successful at generating a sequence for this species. The type specimens were initially labeled by John Wagner as 'types' and 'paratypes' of his manuscript species ' P. patricki '. We have not used his intended name, but have left his labels on the specimens.
