New spider records from Portugal 55 gyne are nearly the same for the Portuguese and Majorcan specimens with the proportion of the structures showing only minor variation, also in dark parts of the vulva with dense sc­ lerotizations not well presented in Fig. 8. Further images of S. validus epigynes are available from Oger (2017), also showing variation in the depth of sclerotization and minor variation in proportions. As a female belonging to this species was found at the same locality as the male of S. dolanskyi sp. n. described above, potential conspecificity was carefully considered and the two specimens were compared side by side.They differ in the configuration of eyes, being more compact in S. dolanskyi sp. n. Relative to S. validus, S. dolanskyi sp. n. has a distinctly less elongate sternum, distinctly shorter maxillae compared to their width (in S. validus they are nearly twice as long as wide, compare to fig. 4b), cheliceral dentation (only two, relatively smaller promarginal teeth are present in S. validus , none on the retromargin), indistinct extensions to the coxae, and more spinose legs. Also, two species with similar epigynes would not be expected to possess very different male palps. Apostenus crespoi Lissner spec. nov. (Liocranidae) (Figs 9–11) Etymology. The species is named in honour of Luís Carlos da Fonseca Crespo in recognition of his work with Iberian and Macaronesian spiders. Type material . PORTUGAL: Setúbal, Arrábida near Aze­ itão (N38°30’53’’, W8°59’42”), holotype ♀ , rocky limestone steppe/maquis (195 m), 8.III.2014, Jørgen Lissner leg., CJL- 9645, deposited at NHMD. DNA Barcoding. The specimen was barcoded with a se­ quence of 658 bp obtained from the cytochrome c oxidase region (Barcode of Life Data System, Process ID: GRE­ AR057-17; Sample ID: NHMD-JL-9645). Public barcode data for comparison are at present only available from one congener, A. fuscus Westring, 1851, which is not a particularly close relative with similarity % ranging from 93.5 % to 94.0 % (The Barcode of Life Data Systems 2017). Diagnosis. The new species most closely resembles Apostenus humilis Simon 1932 and A. maroccanus Bosmans, 1999 based on build of the epigyne/vulva. Both species possess a medi­ an septum according to illustrations in Bosmans (1999) and Bosselaers (2009); such a septum was not observable for A. crespoi sp. n. Apostenus algericus Bosmans, 1999 is only known from the male, but is closely related to its other north African congener as judged by their fairly similar male palps, thus it could be expected that the female of this species also posses­ ses a septum. Description of female Measurements (n=1), body length 3.32, carapace length 1.19, width 0.95. Colour . When alive this is a bright reddish - orange species with distinct abdominal chevrons and with indistinct leg an­ nulations (Fig 9). Margin of carapace not darkened. Cara­ pace with transparent hairs , in posterior half also some bla­ ckish ones. Dorsum of opisthosoma with scattered whitish hairs (Fig. 9), the whiteness augmented by flash photography and they may just be transparent hairs positioned at an ang­ le reflecting flashlight. Dorsum, sides and venter with trans­ parent hairs of various lengths and thicknesses, the thicker ones slightly swollen and plumose similar to hairs depicted in Ubick & Vetter (2005, f. 17) . Colours of carapace and legs fade to yellow-brown in alcohol except for the dark - brown fovea, the very faint brown reticulations and the annulations of the legs becoming indiscernible. The darker parts of the opisthosoma including the chevrons remain brown, but the transverse orange bands lose their orange colour and become pale. Remaining description of colours refer to alcohol preser­ ved specimen. Chelicerae and sternum yellow-brown. All eyes ringed with black. Tibiae, metatarsi and tarsi slightly darker than coxae, trochanter and femora. Venter of opisthosoma with a pale median band . Prosoma. Carapace smooth with a narrow, protruding head. Eyes in a compact group and of normal size. PME separated by a little more than half a diameter, the sockets of the remai­ ning eyes touching. Eyes of PER equal in size, larger than the AME but smaller than ALE. Eye sizes (lenses): AME 0.047, ALE 0.077, PME 0.064, PLE 0.061; interdistances: AME-AME 0.028, AME-ALE 0.016, PME-PME 0.069, PME-PLE 0.053 , ALE-PLE 0.060, width of eye rows: AER 0.284, PER 0.353. Clypeus low about 0.5 the diameter of an AME. Labium shaped like a triangle with rounded cor­ ners, more than 1.5 times wider than long, slightly less than half the length of the endites. The latter are rectangular with rounded corners, about 1.5 times longer than wide. Chelice­ ral promargin with three minute, discrete teeth, retromargin with two small discrete teeth. Sternum scutiform, projecting between coxae IV. Opisthosoma. Elongate oval, with four chevrons, densely covered with hairs, however those of the dorsum all fallen off in alcohol-preserved specimen, the hairs clearly visible in photo of live specimen (Fig. 9). Spinnerets are obscured by dense hairs, but seem similar to those of A. californicus which are well described and complemented with SEM images in Ubick & Vetter (2005) . Legs. Femur I-II with two macrosetae in dorsal midline, III- IV with three. Femur I with additional strong prolateral mac­ Fig. 9: Apostenus crespoi Lissner spec. nov.
