Hogna nonannulata can be distinguished from all other Madeiran Hogna by the aspect of its legs, without annulations or bright yellow or orange setae (Fig. 24D View Figure 24 ). In addition, males have an elongate cymbium tip, clearly longer than the length of the alveolus of the bulb (Fig. 24A View Figure 24 ). We could not revise any female materials, for which we propose that the leg aspect can be used to diagnose females.


Male (CRBALC0701): (Fig. 24 View Figure 24 ). Total length: 18.6; carapace: 10.3 long, 8.2 wide.

Colour: carapace greyish brown with transverse yellowish bands, generally covered with short black setae, except anteriorly and laterally, provided with short white setae and long black setae; median yellow longitudinal band present, anteriorly broadened, with suffused greyish brown patches; two yellow marginal bands, suffused with greyish brown patches; ca. seven faint blackish striae on each flank. Chelicerae blackish to dark brown, mostly covered with black and white setae. Gnathocoxae very dark orange-brown, labium blackish; sternum yellowish grey, with a faint, longitudinal yellow stripe extending to less than half of sternum length. Legs yellow to brown, without any clearly coloured patch, just scattered areas suffused with grey, grey setae present in tibia, metatarsus and tarsus. Pedipalpal femur, patella, and tibia yellow, except cymbium, brown. Abdomen with both short and long black setae, additionally with short greyish white setae; with a pair of anterolateral faint blackish patches, extending laterally into grey flanks, interspersed with greyish white patches; a median greyish lanceolate patch is bordered by two yellowish longitudinal bands interconnected in anterior half, posteriorly by means of faint dark chevrons; venter yellowish except around spinnerets, dark grey, with small blackish patches scattered laterally.

Eyes: MOQ: MW = 0.8 PW, MW = 1.2 LMP, MW = 1.3 AW; Cl = 0.7 DAME. Anterior eye row slightly procurved.

Legs: Measurements: Leg I: 40.9, TiI: 10.8; Leg IV: 43.0, TiIV: 9.8; TiIL/D: 8.8. Spination of Leg I: FeI: d1.1.0, p0.0.2; TiI: p1.0.1, v2s.2s.2s; MtI: p1.0.1, r1.0.1, v2s.2s.1s. MtI with very dense scopulae.

Pedipalp: cymbium with two prolateral spines, one basal, the other at rim, apically with four dark macrosetae, Fe with two dorsal and an apical row of four spines, Pa with one prolateral spine, Ti with one dorsal, one dorsoprolateral, and one prolateral spines. Tegular apophysis with ventral spur short, blunt, with a short straight ridge leading to a wide apical point; terminal apophysis separated from subterminal apophysis due to a clearly visible excavation, blade-shaped with sharp end; embolus moderately elongated, with tip directed anteriorly; palea small.

Female: We could not revise any female material.

Intraspecific variation.

Carapace length, males: 7.2-11.3. Smaller males have proportionally longer tibial spines than longer males.


This species is known from the southern coastal area of Câmara de Lobos in the island of Madeira (Fig. 25 View Figure 25 ).


Hogna nonannulata can be found in coastal shrub- or grassland and rocky areas.

Conservation status.

It was not previously possible to assess H. nonannulata according to the IUCN Red List criteria given the scarcity of past information, hence a status of Data Deficient was suggested ( Cardoso et al. 2018e). Its known distribution is now limited to the area of Camara de Lobos in the southern coast of Madeira Island, an area with no remaining natural habitat beyond the rocky areas. With an EOO and AOO of 4 km2 and a single location threatened by urban and agricultural pressure, if the trend of the species is negative its status might be Critically Endangered.
