Description of the studied specimens from the Canary Islands. Body length up to 0.95 mm, excluding antennae. Base colour pale yellow with dark blue longitudinal patches, with the typical five longitudinal stripes only interrupted on abdominal tergite IV ( Figs 3I View Figure , 4Q View Figure ).

Head. Eight eyes, GH a little smaller than EF. Antennae length 0.78 mm, 2.12 times the length of the head (n = 3 for all measurements). Ant IV with apical vesicle bilobed. The relative length of Ant I/II/III/IV = 1/1.82/1.73/ 2.51. Prelabral chaetae ciliated. Labral papillae multispinose ( Fig. 20E View Figure ). Lateral process of labial papilla E 1/3 shorter than the papilla.

Body. Length ratio of Abd IV/III = 4.11 (n = 3). Trochanteral organ with approximately 20 chaetae. Tibiotarsus not sub-segmented, without smooth chaetae, except for smooth terminal chaeta on legs III. Claw with four teeth: paired at 50% and first unpaired at 75% from basis; dorsal teeth not totally basal ( Fig. 20F View Figure ). Empodium lanceolate, with smooth external lamella in leg III. Tenent hair clavate. Length of manubrium and dens 0.31 and 0.39 mm, respectively. Manubrial plate with 3–4 chaetae and two pseudopores. Mucro with teeth similar in size (subapical smaller in one specimen), mucronal spine reaching the tip of the subapical tooth ( Fig. 20G View Figure ).

Macrochaetotaxy ( Figs 20A–D View Figure ). Simplified Mc formula: 3-1-0-3-2/2-4/2-3/1-2-1/0-2(3)-3(4)-2-2.

Head with Mc An2, An3a1 and An3 on H1 area, Mc a5 on H2 area, Mc S0, S1, S2, S3, S4, S 4i, S5 and S 5i present on the sutural zone (three Mc on H4 area. H5 area with Mc Ps2 and Ps5).

Mesothorax: area T1 with two Mc (m1 and m 2i); T2 with four Mc (m4, m 4i, a5 and m5). Abdomen: Abd II area A1 with two Mc (a2 and a3), area A2 with three Mc (m3, m3ep and m3ea); Abd III with one Mc each on areas A3 (a1) and A5 (m3e) and two Mc on A4 (a2 and a3); Abd IV with 2–3 Mc on A7 (A3, and B3 sometimes one additional Mc C1a), 3–4 Mc on A8 (A4, B4 and C2a, sometimes one additional Mc A e4) and two Mc on A9 (A5 and B5) and A10 (A6 and B6).

Ecology. Found in moss and grass in a Pinus canariensis  forest.

Remarks. The colour pattern indicates that the observed specimens could be E. cf. quinquelineata  , although four constant differences occur in the four specimens from the Canary Islands: a multispinose labral papillae, three Mc on H4 area of the head, four Mc on T2 area on Th II, three Mc on m3 series on Abd II and a Ratio Abd IV / Abd III> 4. These characteristics distinguish it from E. quinquelineata  . Other species have a similar colour pattern, and these are compared on Table 1. The species E. grimanesae  sp. nov. shares all considered chaetotaxy with E. cf. quinquelineata  ( Table 1) but the species are separated by two characteristics: lateral process of labial papilla E reaching to the papilla end, and claw dorsal tooth at level of internal teeth in E. grimanesae  sp. nov., while in E. cf. quinquelineata  the lateral process is short (1/3) not reaching the papilla end, and the dorsal tooth of claw is basal. Furthermore, the colour is completely different.

One specimen from Artenara, with the same capture date, is juvenile and has 1-0-1 Mc on Abd III, and has not been taken into account in the description.
