Material examined
One female and one male, Chrysi Isl., Crete, Greece, 15 June 1992, collected by Dr. Apostolos Trichas; one female and one male, Keratidi, Crete, Greece, 15 November 1990, same collector; one female and one tritonymph, Omalos, Crete, Greece, 27 June 1990, same collector ( Map 1 View Map 1 ) .
The biotope of this species includes supralittoral as well as some macchia and woody areas up to 1400 m a.s.l.; all specimens were collected by the use of Barber traps. The carbonate substrate is characterized by diverse vegetation, consisting of different species of Quercus , Tamarix smyrnensis Bunge , Tamarix parυiflora DC., Tamarix dalmatica Baum , Sarcopoterium spinosum (L.) Spach, and a few representatives of some Poaceae .
The specimens analysed are housed in the collections of the Institute of Zoology, Faculty of Biology, Belgrade, Serbia ( IZB 1004–1009 ) .
Supplementary description
The carapace is somewhat longer than broad or broader than long ( Table I; Figures 12 View Figures 8–14 , 19 View Figures 15–19 , 24 View Figures 20–26 , 34 View Figures 30–36 , 41 View Figures 37–42 ). The epistome is triangular and apically rounded ( Figures 10 View Figures 8–14 , 18 View Figures 15–19 , 23 View Figures 20–26 , 33 View Figures 30–36 , 40 View Figures 37–42 ). With four eyes ( Figures 12 View Figures 8–14 , 19 View Figures 15–19 , 24 View Figures 20–26 , 34 View Figures 30–36 , 41 View Figures 37–42 ). The carapacal setal formulae are: 7+6+6+10529, and 4+6+6+9525 setae (males; Figures 12 View Figures 8–14 , 24 View Figures 20–26 ), 6+6+6+12530, 4+6+ 6+11527, and 4+6+6+10526 setae (females, Figures 19 View Figures 15–19 , 34 View Figures 30–36 ), and 4+6+6+8524 setae (tritonymph; Figure 41 View Figures 37–42 ).
The number of setae borne on tergites I–X is variable: 9-11-12-14-15-14-14-12-12-11, 9-12-13-13-14-14-14-13-13-12 (males), 9-13-14-16-16-14-14-13-12-11 (female) and 8- 12-12-13-13-12-11-11-11-10 (tritonymph).
In the male, sternite II carries 16–18 setae, and 13 and two setae are borne in the female and tritonymph, respectively. Sternite III has 27–29 setae and three or four suprastigmatic microsetae on either side (male), 17 setae and four or five microsetae along each stigma (females), and eight setae and two small setae along each of the stigma ( Figures 13 View Figures 8–14 , 25 View Figures 20–26 ). Sternite IV with 15–19 setae and three or four suprastigmatic microsetae along each of the stigma (males), 14–17 setae and three or four tiny suprastigmatic setae on either side (females; Figures 17 View Figures 15–19 , 29 View Figures 27–29 , 35 View Figures 30–36 ), and 10 setae and two small setae on either side (tritonymph). Sternites V–X each with 19-21-17-18-15-14, 18-15-14-14-13-12 (males), 19-18-19-17-14-13, 20-18-18-17-15-14, 21-18-17-18-14-13 (females) and 13- 13-14-13-13-12 setae (tritonymph). Of these, two median setae on each of the sternites are slightly anterior—at a distance of 2.00–3.20 diameters of their bases—to other posterior setae.
The movable and fixed cheliceral fingers carry 8–12 (males), 9–11 (females), and nine small teeth, apically rounded (worn or lamellar in some ‘old’ specimens), and 12–17 (males), 13–16 (females) and 14 such teeth (tritonymph). On the movable finger, these end well below the galeal seta (gl) ( Figures 14 View Figures 8–14 , 26 View Figures 20–26 , 36 View Figures 30–36 , 42 View Figures 37–42 ). A single chaeta is borne on the movable cheliceral finger (adults, tritonymph), and six to seven (males), and six such setae are carried by males and tritonymph, respectively.
Flagellum seven- or eight- (males), eight- (females), and eight-bladed (tritonymph), characteristic of the genus.
Manducatory process with five (adults) and four long setae (tritonymph). Pedipalpal articles ( Figures 9 View Figures 8–14 , 16 View Figures 15–19 , 21 View Figures 20–26 , 28 View Figures 27–29 , 32 View Figures 30–36 , 38 View Figures 37–42 ) as in the type specimens ( Ćurčić et al. 2006). The movable chelal finger with 63–66 (males), 60–63 (females), and 48 small teeth (tritonymph). Trichobothriotaxy as in type specimens ( Figures 8 View Figures 8–14 , 15 View Figures 15–19 , 20 View Figures 20–26 , 27 View Figures 27–29 , 30 View Figures 30–36 , 37 View Figures 37–42 ) ( Ćurčić et al. 2006). Fixed chelal finger with 63–68 (males), 63–66 (females) and 53 small and close-set teeth (tritonymph).
The pedipalpal femur is 3.79–4.40 (males), 3.66–4.07 (females), and 2.95–3.60 times as long as broad (tritonymphs) ( Table I). The pedipalpal patella is 2.43–2.56 (males), 2.275– 2.44 (females), and 2.18–2.36 (tritonymphs) times longer than its breadth (tritonymphs). The pedipalpal chela length to breadth ratio is 2.74–3.51 (males), 3.21–3.76 (females) and 3.36–3.60 (tritonymph). Chelal fingers of the same length or slightly longer than chelal palm ( Figures 8 View Figures 8–14 , 15 View Figures 15–19 , 20 View Figures 20–26 , 27 View Figures 27–29 , 30 View Figures 30–36 , 37 View Figures 37–42 ; Table I).
Tibia IV and metatarsus IV each carry a single long tactile seta, but tarsus IV bears two such setae ( Figures 11 View Figures 8–14 , 22 View Figures 20–26 , 31 View Figures 30–36 , 39 View Figures 37–42 ; Table I).
The measurements of different body structures and morphometric ratios are presented in Table I.
Generally, the additional examples analysed conform to the original description of E. apostolostrichasi . Some minor distinctions are due to the intra- and interpopulation variability of this taxon from different localities.
Distribution
This taxon is an endemic and palaeorelict inhabitant of different ecosystems (ranging from supralittoral to mountainous areas) in Crete, Greece.
