Gymnoscirtetes morsei Hebard, 1918: 142-143.

Diagnosis.

Most easily differentiated from the other species in the group based on the shape of the male cerci, which in G. morsei are decurved apically to an acute point (Fig. 6A, B View Figure 6 ), and by the shape of the male genitalia which have the dorsal valves rounded apically (Fig. 6G View Figure 6 ). The tubercle of the subgenital plate is often broader in most individuals of G. morsei , especially those in the western portion of the range.

Male measurements.

(mm): (n = 14) Body length 13.2-17.0 (mean = 14.6); pronotum length 1.9-2.6 (mean = 2.26); hind femur length 6.1-7.9 (mean = 6.9); cerci length 1.2-1.5 (mean = 1.3); basal width of cercus 0.4-0.7 (mean = 0.6); mid-cercal width 0.2-0.3 (mean = 0.2); cerci apex width 0.3-0.4 (mean = 0.4). tubercule length 0.3-0.4 (mean = 0.3); tubercule width 0.2-0.3 (mean = 0.2).

Female measurements.

(mm): (n = 7) Body length 19.5-21 (mean = 20.3); pronotum length 3.0-3.2 (mean = 3.1); hind femur length 9.0-9.8 (mean = 9.3).

Distribution.

Mobile Bay (Baldwin County, AL) east through the panhandle of Florida to Bay and Jackson counties (Fig. 12 View Figure 12 ).

Habitat.

Hebard (1918) describes the type locality at De Funiak Springs, Florida as being "a boggy area of wire-grass and bog plants, which was not more than fifteen yards wide by forty yards long". At Splinter Hill Bog, in Baldwin County, AL (Fig. 13A View Figure 13 ), G. morsei occurs in a large bog dominated by Sarracenia leucophyllia Raf. and other carnivorous plants.
