Diagnosis.

Adult males of Nannaria conservata   are distinct from other Nannaria   and the nearby N. hardeni   sp. nov. based on the following combination of characters: Gonopods. Gonopodal acropodite gently curving dorsomedially before apex, not medially as in N. hardeni   sp. nov.; tip simple, blunt. Telepodite basal zone height < 1/2 length of acropodite, not > 1/2 as in N. hardeni   sp. nov. Prefemoral process acicular, reduced, not subequal to height of telopodite basal zone and crossing acropodite as in N. hardeni   sp. nov. Prefemoral spine acicular and paralleling prefemoral process (Fig. 109B View Figure 109 , red arrow), not blunt and widely separated from prefemoral process as in N. hardeni   sp. nov. Color. In his redescription of N. conservata   , Shelley (1975) describes its color as "olive-brown with a pink epiproct and paranota …” The single female individual collected for this revision conformed to Shelley’s description, but was placed in 100% EtOH in the field not photographed alive.

Measurements.

♂ ( VMNH, NAN0388): BL = 21.2, CW = 2.8, IW = 1.6, ISW = 0.8, B11W = 3.2, B11H = 2.3.

Variation.

There is no notable variation between individuals of N. conservata   , with the exception of an abnormal male with three gonopods which Shelley (1975) illustrated and discussed.

Distribution.

Known only from a small area around Raleigh and Durham, North Carolina (North Carolina: Person, Orange, Wake and Franklin counties; Suppl. material 7; Fig. 128 View Figure 128 ). Distribution area: 1,820 km2; status: SRE.

Ecology.

As no fresh identifiable material was collected for this revision, the authors cannot comment on habitat preference. However, Shelley (1975) noted that specimens were never found in moist areas, and instead were discovered under pine litter and in sandy, dry soils. As Shelley (1975) noted, this is unusual for a majority of xystodesmid species.

Etymology.

Chamberlin (1940) gives no etymology for N. conservata   , but the specific name is seemingly a femininization of the Latin conservo, meaning conserve. This may be in reference to the conservation efforts which take place within its type locality, Duke Forest.

Note on clade membership.

The authors were unsuccessful at collecting specimens of Nannaria conservata   for the present study, so DNA sequences, molecular phylogenetic relationship, and taxonomic affinities between N. conservata   and the rest of the Nannaria minor   species group remain unknown. A female specimen from Raleigh, Wake County, North Carolina was collected and sequenced, and was placed within the Nannaria paupertas   clade. The only species of Nannaria   known from Wake County is N. conservata   . However, as N. conservata   shares none of the gonopodal characters that unite the Nannaria paupertas   clade, and in light of the possibility that the female from Wake County represents an undescribed species, the authors refrain from placing N. conservata   within the Nannaria paupertas   clade and leave the taxonomic affinity of N. conservata   to be addressed in a future study.

Type locality.

United States, North Carolina, Durham County, Durham.

Notes.

In the original publication, Chamberlin (1940: 57) did not designate a type, but he describes only a male specimen which is therefore the holotype by monotypy. Chamberlin did not mention the collector of this specimen, but Shelley (1975: 180) reported that the type specimen was collected by N. B. Causey on November 12, 1939.
