(Fig. 20). Ocular process steep in front. Eye group posterior row longer than anterior row (AR/PR = 0.93), width > length (PR/HE = 2.19), AME one diameter apart, diameter ALE = PLE. POP broken between ALE-PLE and between ALE-AME. Chelicerae dark reddish brown with longitudinal zones of brilliant white pubescence, colour contrasts with that of carapace. Fangs: long, slender, sharp with a smooth keel. Rastellum compact group of strong teeth on a small rastellar process. Abdomen dorsal, central zone, creamy white with a complex pattern of dark pigmentation, lateral and ventral zones greyish. Fine setae with undercover of fine hair. Ventral prosoma yellow, brownish around the edges. Sternum with evenly distributed setae, posterior sigilla ‘egg-shaped’. Labium slightly darker than sternum, labial furrow comparatively narrow. Maxillae five strong somewhat spiky cuspules in irregular rows. Legs and palps uniform brown except for the dark dorsal zone and the white pubescence on all femora. Spermathecae (Fig. 43). Spinnerets (Fig. 44), PMS vestigial digitiform. PLS basal segment longer than medium and distal segment together, spigots on proximal segment in a triangular field, colour slightly lighter than ventral abdomen. Variation. Females (n = 4). Measurements (mm). BL=20.5–23.2, CL=7.7–8.6, CW=5.9–6.6, SL=4.1–4.5, SW=3.1–3.5, LP=11.7–12.5, LL1=18.0–19.4, LL2=17.0–18.4, LL3=16.2–17.5, LL4=23.5–26.6. Patellar spine formulae. PSPvar [p=2; I=2; II=2; III=2; IV=0] RSPvar [p=0; I=0; II=0; III=0; IV=0] Distribution (Fig. 52). All currently recorded collection sites for N. uncinata are given in Table 1 and are indicated as dots in Fig. 52. The estimated distribution range (dark zones in Fig. 52) is restricted to the Algarve. Natural history. We have no information about the structure of burrow of this species. The species is apparently not uncommon in the far south of Portugal, though very limited in its distribution. The males wander in autumn. Two males were collected in pitfall traps in a Eucalyptus plantation in the first week of October. A third male (not included in our description) was collected by S. Huber during heavy rain in the last week of October 2006 near Alte in the Algarve. Nemesia ungoliant sp. n. Figs. 9, 10, 21, 22, 33, 34, 45, 46, 53 Types. Male holotype: leg. P. Cardoso, nr 5004-1 collected 24 Sept. 2002, deposited at the MNHN Paris Nr. AR14327; Female paratype: leg. P. Cardoso, nr. 5003-2 collected 24 Sept 2002, deposited at the MNHN Paris Nr. AR14328. Other paratypes (11 males and 2 females) included in the type collection are deposited in the NMR under the numbers: 9972.4029– 9972.4034, and seven males are deposited in the ZMUC (under collection numbers yet to be appointed). Type locality. Barrenta (N39º34.316, W08º45.686) Eucalyptus plantation. Etymology. Named after Tolkien’s mythical spider acting in “Silmarillion” and other writings. Diagnosis. The dark, shiny appearance, the lack of pubescent hair on the carapace, the double row of crest setae, and the high elevation of the caput in females, N. ungoliant resembles the species grouped in the ‘subgenus’ Haplonemesia (Simon 1914). It differs from the Haplonemesia in lacking the diagnostic palpal spine pattern of this group, the much smaller size of the adult spiders, the morphology of the spermathecae which are straight (compare
Fig. 45 with Blasco 1986 p.346 Fig.1c) instead of bent and the embolus being slightly hooked instead of smoothly curved (compare Fig. 33 with Frade & Bacelar 1931 p.223 Figs. 1-2). Description. Male holotype. Measurements (mm) BL=10.4, CL=4.2, CW=3.4, SL=2.2, SW=1.7, LP=5.5, LL1=12.6, LL2=12.4, LL3=12.2, LL4=16.4. Patellar spine formulae. PSP [p=1–1; I=1–1; II= 2–2; III= 2–2; IV= 1–1] RSP [p=0–0; I=0–0; II= 0–0; III= 1-1; IV= 1–1]. Qualitative characters. Dorsal habitus (Fig. 9). Carapace colour almost uniform brown, with slighter darker areas around the eyes and the fovea, pubescence absent, crest setae in irregular central longitudinal group setae of different strength flanked on either side by a sub-row of thinner setae, fringe setae. Clypeus shorter than one diameter of ALE with five equal-sized edge setae. Fringe setae and thorax setae strongly developed. Caput slightly elevated (Fig. 21). Eye group trapezium with AR as shortest parallel side (AR/PR=0.9), width > 2x height (AR/EL=2.3), ALE largest (ALE/PLE=1.4), AME’s less than their diameter apart. POP dark black, connecting all eyes. Ocular process low and sloping both in front and behind. Fovea sickle shaped recurved, central groove absent. Chelicerae basal segment uniform brown, not contrasting with colour of carapace, lateral lines indistinct, seven furrow teeth, fang-keel serrated. Maxillae distal process very small, cuspules, three on either side, in short rows and pointed in shape. Sternum colour uniform yellowish brown, same colour as ventral coxae and maxillae, uniform setae cover, anterior and median sigilla round, posterior sigilla oval, distanced about their longest diameter from the sternum edge. Labium colour slightly darker than sternum, labial furrow shallow, wide, glabrous. Legs and palps brown with greyish longitudinal dorsal zones and black pubescence dorsally and laterally on the femora, spines on all segments including the ventral tarsi, trichobothria patterns as typical for the genus, scopula thin, all paired claws with double combs, maculae absent. Abdomen dorsally dark colour, ventrally lighter, dense group recurved setae in anterior dorsal group, no clear colour pattern. Spinnerets similar colour as ventral abdomen. PMS club-shaped, reduced. PLS basal segment longer than median + distal segment, maculae absent. Clasper hook strong and inwardly curved, clasper field restricted to central ventral metatarsus. MTF4 ratio Me4
