Fjellberg leg.: Gran Canaria, El Brezal del Palmital, litter in Ilex stand, 9.I.1988, 31A/88, coordinates 28.10958°N, 15.59709°W, 550 m a.s.l., (Loc. 50) one female on slide (MZLU-VAR00001341) and 13 specimens in ethyl alcohol (MZLU-VAR00001342 to MZLU-VAR00001354), and soil/litter, Ilex laurisilva, one female on slide (MZLU-VAR00001355); Gran Canaria, Mt. del brezo, Artenara, moss, pine forest, 11.I.1988, 50/88, coordinates 28.02829°N, 15.66135°W, 1130 m a.s.l., (Loc. 48) one female on slide (MZLU-VAR00001356).

Description. Body length up to 2.62 mm, excluding antennae (Holotype: 2.20 mm; average: 2.19, n = 5). Ground colour very light blue, with a great extension of dark pigment in many specimens, leaving the pale ground base on posterior half head, central Th II, posterior dorsolateral Th III, central Abd II and tip of Abd VI; the paler specimens appear as transversal bands on Th III to Abd II and central Abd IV; some variations are shown in Figure 2I ; legs and antennae almost totally covered with dark pigment ( Figs 2F , 4H ).

Head. Eight eyes, GH smaller than EF. Antennae length 1.32 mm, 2.84 times the length of the head (n = 4 for all measurements); Ant IV with apical vesicle simple (absent in one specimen); relative length of Ant I/II/III/IV = 1/1.78/1.77/1.86. Prelabral chaetae ciliated. Four labral papillae, laterals smooth and centrals rough ( Fig. 10E ). Lateral process of labial papilla E 1/3 shorter than the papilla.

Body. Length ratio of Abd IV/III = 4.06 (n = 5). Trochanteral organ with approximately 35–40 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 tooth basal ( Fig. 10F ). Empodium lanceolate, with smooth external lamella in leg III. Tenent hair clavate. Length of manubrium and dens 0.44 and 0.57 mm, respectively (n = 4). Manubrial plate with 6–7 chaetae and two pseudopores. Mucro with teeth similar in size, mucronal spine reaching the tip of the subapical tooth ( Fig. 10G ).

Macrochaetotaxy ( Figs 10A–D ). Simplified Mc formula: 3-2-0-3-2/2-4/2-3/1-2-1/1-4-3-2-2. Head: Three Mc An on H1 area (An2, An3a1 and An3), two Mc (A5 and A6) present on area H2; three Mc on Area H4 (S1, S3 and S4) and with Ps2 and Ps5 on Area H5. 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 m3e); Abd III with one Mc each on areas A3 (a1) and A5 (m3e) and two Mc on A4 (a2 and a3); Abd IV with one Mc on A6 (B1; absent in one specimen), four Mc on A7 (A3, B2, C1 and E1), three Mc on A8 (A4, B4 and C2a) and two Mc on A9 (A5 and B5) and A10 (A6 and B6).

Ecology. Found always on moss and in litter in forest of Pinus and laurisilva.

Etymology. Gazmira was a notable woman who served as a mediator between the captive inhabitants of La Palma, the Cabildo of Gran Canaria and the governor Maldonado in 1492.

Remarks. If the macrochaetotaxy of Th II and Abd II–III is considered simultaneously, no species of Entomobrya previously described with the chaetotaxy shares the presence of the simplified formula for these tergites (2-4/2-3/1-2-1). Two Canary Islands species described in this paper ( E. cf. quinquelineata and E. grimanesae sp. nov.) share the macrochaeta formula for these three tergites. The colour pattern is completely different, as shown in the plates of photographs and colour pattern; additionally, the differences in labral papillae are clearly multispinose on E. grimanesae sp. nov. and E. cf. quinquelineata and smooth on the sp. nov.; A6 is present on the on the head of the sp. nov. and absent on both related species; the chaetotaxy of Abd IV is different (1-4) on areas A6 and A7 on the sp. nov. and 0-0(2) or 0-2 for E. grimanesae sp. nov. and E. cf. quinquelineata , respectively. Furthermore, E. grimanesae sp. nov. has the dorsal tooth of the claw near at level of lateral teeth, and this tooth is basal in the sp. nov. .
