Kočárek leg. & I. Horká leg.” ( UNOV) .

Diagnosis. Similar to the rest of the species of Canarilabis in terms of external morphology, males can be identified by the unique combination of the following characters: tegmina absent; lateral glandular folds always present, developed on tergites 3 and 4, or only on tergite 4; tergites 6–9 rugoso-striate at sides; penultimate sternite with posterior margin subtrun- cate, somewhat concave, truncate part as wide as 1/3 of maximal width of sternite, manubrium approximately 2 times longer than penultimate sternite; outer margin of paramere with angular projection. Females are indistinguishable.

Description. Male. Body blackish brown, shiny; antennae unicolour, reddish brown; distal half of labrum yellow; legs unicolour, forceps reddish brown with lateral and dorsal edges black. Cuticle punctured, shiny; tegmina and wings absent. Total body length without forceps: males: 21.4–26.3 mm, holotype 25.2 mm; females: 18.0– 24.7 mm. Length of forceps: males: 6.5–8.8 mm, holotype 8.2 mm; females: 4.3–7.1 mm.

Head (fig. 3A) as long as wide; post- frontal and coronal sutures fine but distinct; frons convex. Eyes approximately 0.5 times as long as head length behind eyes. Antennae multisegmented and composed of up to 28 pubescent antennomeres, left antenna of holotype 18 antennomeres, right antenna of holotype 25 antennomeres (both incomplete); antennomere 1 (scape) long, narrowed basally, widened terminally, as long as antennomeres 2–4 combined; antennomere 2 (pedicel) transverse, only slightly longer than wide; antennomere 3 cylindrical, 2 times longer than wide; antennomere 4 slightly longer than wide; the rest of antennomeres conical, each subsequent antennomere slightly longer than the previous antennomere.

Pronotum (fig. 3A) smooth, approximately as long as wide, widened posteriorly; anterior margin nearly straight, posterior margin rounded and shallowly emarginated in middle, lateral margins concave in middle. Median sulcus fine but distinct. Meso- and metanotum transverse, smooth; mesonotum truncate posteriorly, metanotum broadly emarginated posteriorly; median sulcus visible on both mesonotum and metanotum. Prosternum 1.5 times longer than wide, constricted laterally in posterior third, posterior margin truncate; mesosternum approximately as long as wide, posterior margin broadly rounded; metasternum approximately as long as wide, trigonal, widest at base and tapering to truncate tip. Legs comparatively short; femora

stout, covered by sparse long setae; tibiae shorter than femora, with sparse setae, setae longer on outer edge than on inner edge; tarsomeres pubescent laterally and ventrally, smooth dorsally; tarsomere 1 longer than tarsomeres 2–3 combined, tarsomere 2 short, quadratic; claws bent inward, gradually narrowing toward the tip; arolia absent.

Abdomen (fig. 3A) sparsely punctulate and shiny.Tergites (except for ultimate tergite) convex and somewhat widened posteriorly; lateral glandular folds developed on tergites 3 and 4 or only on tergite 4; tergites 6–9 rugoso-striate at sides. Ultimate tergite transverse; sides convex, slightly narrowed anteriorly, median part with 8–10 longitudinal, finely dotted stripes; lateral longitudinal ridge rugoso-striate, sinuate, with tuberous projection at the base; posterior margin slightly concave medially. Penultimate sternite narrowed posteriorly, with posterior margin subtrun- cate, somewhat concave, truncate part as wide as 1/3 of maximal width of sternite (fig. 3E), and manubrium approximately 2 times longer than penultimate sternite. Pygidium flat, not protruding, trigonal, with oval depression in middle. Forceps symmetrical (figs. 3B, C, 4F–H), or only slightly asymmetrical in distal third; both branches subcontinuous and stout at base, gradually tapering apically, nearly straight in basal two-thirds, and slightly incurved afterward; forceps trigonal in basal half and cylindrical in distal half; inner margin crenulated, teeth irregularly spaced, dorsal edge without teeth, elevated in basal one fourth.

Genitalia (figs. 3F, 4I, J) with two penises, deeply excised, V-shaped, with short parameres; parameres 1.6–1.7 times longer than wide, widest in middle, with external projection pointed, external edge trigonal, convex in the basal half and concave in the apical half, internal edge broadly concave; apical angle broadly convex. Penis 1.5 times longer than the paramere, tip rounded, cuticle finely serrated; virga not observable.

Female. Agrees with male in most characters except the following: mesonotum broadly concave posteriorly; lateral glandular folds on tergites 3 and 4 not developed; tergites 6–9 smooth, not rugoso- striate at the sides; ultimate tergite with lateral longitudinal ridge less developed. Penultimate sternite trigonal, narrowed posteriorly, with posterior margin truncated. Forceps (fig. 3D) with simple and straight contiguous branches, weakly regularly concave from base to tip.

Distribution. Canary Islands: El Hierro.

Etymology. The specific epithet is the Latinised adjective derived from the name Hierro with added suffix -ensis, denoting the place of origin.
