Dalmasula griswoldi Szüts and Ubick , new species
TYPES: Male holotype, female allotype, and three male and one female paratypes taken from dunes to the north of Muizenberg , 34°06′S, 18°27′E, Western Cape, South Africa (June 16–30, 1991; R. Legg) GoogleMaps , deposited in MRAC (173912, PBI _ OON 36053 View Materials ) .
ETYMOLOGY: The specific name is a patronym in honor of Charles Griswold, who first discovered the South African members of this genus.
DIAGNOSIS: Males differ from those of the other Dalmasula species in having a more complex embolar region with a dorsal lobe terminating in two ribbonlike lamellae and a broad ventral lobe terminating in a slender spiral prong (figs. 275–288); females differ in having an epigynum with the anteromedian coupling ridges C-shaped and widely separated, and an internal median process with a slender stalk and a rounded head (figs. 293–299).
MALE (PBI_ OON 36091 View Materials , figs. 263–288): Total length 2.33. Posterior eye row procurved from front. Chelicerae anterior face unmodified.

Gamasomorphinae Petrunkevitch, 1923: 172.
“Pseudogamasomorphinae” (nomen nudum): Dumitresco and Georgesco, 1983: 103.
DIAGNOSIS: The bulk of the currently recognized oonopid genera (i.e., all those except Orchestina , Sulsula , Dalmasula , Xiombarg , Unicorn , and Cortestina ) are here assigned to the Oonopinae , and are characterized by the absence of a heavily sclerotized, thick-walled sperm duct in the male palp. This absence presumably reflects a major transformation in palpal mechanics. With the exception of the New Zealand genus Kapitia , all known oonopines have a distinctively clumped eye arrangement and a 3-3-2-2 tarsal organ receptor pattern.
RELATIONSHIPS: So far as is known, a 4-4-3-3 tarsal organ receptor pattern and an H-shaped eye arrangement are retained only in Kapitia , suggesting that this enigmatic, seldom collected New Zealand genus is the sister group of all the other oonopines. Aside from the original description by Forster (1956), information on Kapitia has been supplied only by Paquin et al. (2010), so we present below a redescription of the species. Of particular interest are the teeth on the tarsal claws (figs. 316, 317); it appears that the inner tooth row has been displaced entirely to the tip of the claw, presumably representing a stage in the loss of that tooth row.
Within the massive assemblage of remaining oonopine species united by the reduction to a 3-3-2-2 tarsal organ receptor pattern and a clustered eye arrangement, we can recognize only a few large groupings at this point. Platnick and Dupérré (2010b) suggested that those genera with a distinctly sclerotized cephalothorax might form a monophyletic group; if so, then several genera that were classically placed in the Oonopinae are actually more closely related to the classical gamasomorphines than to Oonops and such similarly soft-bodied taxa as Heteroonops and Oonopoides Bryant. These anteriorly hard-bodied genera include at least Stenoonops Simon , Australoonops Hewitt , Scaphioides Bryant , Khamisia Saaristo and van Harten , and Longoonops Platnick and Dupérré. The classical gamasomorphines might also represent a monophyletic subgroup of this enlarged group. It remains to be seen, for example, whether taxa in the Scaphiella complex, where males have dorsal abdominal scuta that are lacking in females, or the similarly sexually dimorphic taxa in the Dysderina complex, represent independent gains of dorsal scuta in males, or independent losses of dorsal scuta in females. However, even if the presence of a dorsal scutum does not turn out to be a synapomorphy of the classical gamasomorphines, the movement of the male gonopore onto the epigastric scutum may well be synapomorphic for that group. Nevertheless, neither the classical nor the enlarged group could be recognized as a subfamily unless a separate subfamily were to be established for Kapitia and the many other genera that (like Oonops ) have both a soft-bodied cephalothorax and a soft-bodied abdomen can also be shown to constitute a monophyletic group (i.e., a smaller Oonopinae ). At present, we know of no potentially synapomorphic characters supporting that smaller group.
