Diagnosis.

Adult males of Nannaria missouriensis   are distinct from other Nannaria   , and the nearby N. castanea   , based on the following combination of characters: Gonopods. Gonopodal acropodite gently curving medially. Distal zone with medial and lateral flanges at 90° angle to solenomere (Fig. 38B View Figure 38 , red arrow), not with medial flange at 135° angle to tip as in N. castanea   . Acropodite with small medial flange near apex (Fig. 38A View Figure 38 , red triangle), not lacking as in N. castanea   . Telopodite basal zone height ca. 1/3 length of acropodite, not ca. 1/2 length as in N. castanea   . Prefemoral process reduced to small bump arising from top of projected, stout prefemoral spine (Fig. 38A View Figure 38 , red circle), not projected, acicular as in N. castanea   . Color. Tergites with orange paranotal spots (Fig. 39 View Figure 39 ) and occasionally faint orange stripes (Fig. 39 View Figure 39 ). Dark to light brown background. Dorsum of collum smooth with orange margin.

Measurements.

♂ holotype ( NMNH): BL = N/A, CW = 2.9, IW = 1.7, ISW = 0.7, B11W = N/A, B11H = N/A; ♀ paratype ( NMNH, IC): BL = 25.4, CW = 1.6, IW = 1.7, ISW = 0.7, B11W = 3.4, B11H = 2.3.

Variation.

As Hennen and Shelley (2015) noted, there is some slight variation in the prefemoral process and spine between populations of N. missouriensis   .

Distribution.

Known from central and eastern Missouri (Missouri: Cole, Morgan, Phelps, and St. Charles counties, Suppl. material 7; Fig. 129 View Figure 129 ). Distribution area: 10, 977 km2; status: WRE.

Ecology.

Individuals of N. missouriensis   have been collected from mesic deciduous forests dominated by pawpaw, maple, ironwood, and oak, often found under 1-2 cm dark, crumbly soil on hillsides.

Etymology.

Chamberlin (1928) gave no etymology for Nannaria missouriensis   , but it is reasonable to assume that the specific name is in reference the state of Missouri.

Type locality.

United States, Missouri, St. Charles.

Note.

In the original publication, Chamberlin (1928: 155) mentions eight type specimens, one of which he designated as the holotype ( NMNH P-6). Chamberlin (1928) did not mention the sex of the paratypes, but we examined the type material and found three male and four female paratypes, one of which ( NMNH IC) was labeled as an allotype. Type specimens were collected in 1926 by M. J. Brown.
