Glenognatha heleios Hormiga, in Hormiga & Döbel, 1990: 197  , figs. 1–14 (male holotype from Tuckerton, Ocean Co., New Jersey, United States of America, 1.xi.1984, H. Döbel leg., deposited in USNM, examined; Paratypes from the same locality, 6♀ 6♂, 9.x.1984, 3♀ 4♂, 7.xi.1984, H. Döbel leg., deposited in USNM; 1♀ 1♂, 9.x.1984, H. Döbel leg., deposited in AMNH; 1♀ 1♂, 9.x.1984 H. Döbel leg., deposited in MCZ, all examined); Hormiga et al. 1995: 326, figs. 7H –I; Cabra-García et al. 2014: 1029, figs. 1K, 4D, 6 A, 8B; World Spider Catalog 2015.

Diagnosis. Males of G. heleios  can be easily distinguished from all other Glenognatha  species (except G. iviei  ) by the presence of a small pointed basal apophysis on the paracymbium ( Figs. 95FView FIGURE 95, 97HView FIGURE 97); distinguished from G. iviei  by the slightly curved Prt 1 ( Fig. 94 AView FIGURE 94) and by the uncoiled embolus distal portion ( Figs. 95DView FIGURE 95, 97E –GView FIGURE 97). Females resemble those of G. foxi  and G. hirsutissima  by having a basal constriction on the spermathecae ( Figs. 96D –EView FIGURE 96); distinguished from the former by the absence of CFO ( Figs. 94D –FView FIGURE 94) and from the latter by the absence of macrosetae on the ventral surface of femur III.

Description. Male and female described by Hormiga & Döbel (1990). Additional data. Habitus as in Figure 93View FIGURE 93. Femur III and IV without trichobothria. Male and female with three promarginal and four retromarginal teeth ( Fig. 94View FIGURE 94). Male chelicerae with anterior tooth and CFO ( Fig. 94 A –CView FIGURE 94). Palp as in Figures 95E –HView FIGURE 95. Conductor retrolateral apophysis rounded ( Figs. 95B –CView FIGURE 95). Embolus curved prolaterally ( Figs. 97 A, EView FIGURE 97). Female tracheal system as in Figures 96F –HView FIGURE 96. Spermathecae with a basal constriction ( Figs. 96D –EView FIGURE 96). UE entire ( Fig. 96 A –CView FIGURE 96).

Variation. See Hormiga & Döbel (1990).

Distribution. Known in New Jersey state in United States of America ( Fig. 134).
