Namea cucurbita Raven, 1984: 22 (in part; cited paratype specimen QMB S799 from Mt Tenison Woods).
Type material. AUSTRALIA: Queensland: male holotype, Mount Glorious, malaise trap, rainforest, 10 Au-gust–13 November 1983, A. Hiller (QMB S10269). Paratype: 1 male, Tenison Woods Mountain [sic “Mt Tenison Woods”], pitfall trap, 26 June–18 November 1978, G. & S. Monteith (QMB S799).
Diagnosis. Males of Namea gloriosa can be distinguished from those of all other described congeners except N. cucurbita by the size of the isolated, proximal retroventral macroseta on the palpal tibia, which is unusually long (i.e. clearly longer than the length of the palpal bulb) (Fig. 32). Males can be further distinguished from those of N. cucurbita by the shorter embolus (Fig. 34; cf. Rix et al. 2020, fig. 41) and the more slender profile of tibia I (Fig. 31; cf. Rix et al. 2020, fig. 38).
Females are unknown.
Description (male holotype): Total length 19.9. Carapace 7.7 long, 6.1 wide. Abdomen 8.5 long, 4.4 wide. Carapace (Fig. 22) dark chocolate-brown, covered with reflective downy setae (Fig. 24); lateral margins with fringe of anteriorly curved, porrect black setae, longest posteriorly; fovea straight. Eye group (Fig. 25) rectangular, twice as wide as long, PLE–PLE/ALE–ALE ratio 1.0; AME separated by less than their own diameter; PME separated by 4.1 X their own diameter; PME and PLE almost contiguous. Maxillae each with field of ca. 70 cuspules confined to heel and inner proximal corner (Fig. 26); labium without cuspules. Abdomen (Figs 23, 28) elongate-oval, dark brown with course pale beige-brown marbled pattern dorsally, and pale beige-brown ventrally with finer dark brown mottling; covered with short, fine setae. Legs (Figs 22, 29–31) dark brown, with light scopulae on tarsi I–IV and distal half of metatarsi I–II; tibia I with 3 prodorsal, 2 proventral, 3 ventral and 1 retrolateral macrosetae; macroseta v1 large, reaching beyond ventro-distal margin of tibia I (Fig. 31). Leg I: femur ca. 5.7 [damaged], patella 4.0, tibia 4.6, metatarsus 4.7, tarsus 3.1, total length ca. 22.1. Leg I femur–tar-sus/carapace length ratio ca. 2.9. Pedipalpal tibia (Figs 32–34) 2.5 X longer than wide, with isolated, proximal retroventral macroseta (which is longer than length of palpal bulb), 1 retrodistal macroseta, 1 prodistal macroseta, and 2 proventral macrosetae. Cymbium (Figs 32–34) setose, with distal scopula. Bulb (Figs 32–34) sub-spherical, with long, whip-like, reflexed embolus arising from retroventral base of bulb.
Etymology. The specific epithet is derived from the Latin gloriosus (adjective: ‘glorious’, ‘full of glory’), in reference to the type locality of this species.
Distribution. Namea gloriosa is endemic to the D’Aguilar Range, where it is known only from rainforest at Mount Glorious and Tenison Woods Mountain (Fig. 2).
Remarks. This species is extremely rare, and currently known from only two male specimens. Nothing is known of its biology or life history, other than that the two known male specimens were collected wandering in search of females in winter or spring.
