( Figs. 93–97, 134)

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. 95F, 97H); distinguished from G. iviei by the slightly curved Prt 1 ( Fig. 94 A) and by the uncoiled embolus distal portion ( Figs. 95D, 97E–G). Females resemble those of G. foxi and G. hirsutissima by having a basal constriction on the spermathecae ( Figs. 96D–E); distinguished from the former by the absence of CFO ( Figs. 94D–F) 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 93. Femur III and IV without trichobothria. Male and female with three promarginal and four retromarginal teeth ( Fig. 94). Male chelicerae with anterior tooth and CFO ( Fig. 94 A –C). Palp as in Figures 95E–H. Conductor retrolateral apophysis rounded ( Figs. 95B–C). Embolus curved prolaterally ( Figs. 97 A, E). Female tracheal system as in Figures 96F–H. Spermathecae with a basal constriction ( Figs. 96D–E). UE entire ( Fig. 96 A –C).

Variation. See Hormiga & Döbel (1990).

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