Etymology.
The species name refers to the treelike (tree in Greek:
dendron
) ramification of the male T7 gland (in Latin:
glandus
).
Diagnosis.
Among the Macaronesian species the only one with branched male T7 glandular pouches, and among the species with long tegmina in the male the only without prolonged latero-posterior corners on T7.

Description.
Size.
Male. Length of tegmina 4.74–5.28 mm (mean: 4.93 mm), length of pronotum 1.98–2.14 mm (mean 2.05 mm). Female. Length of pronotum 2.18–
2,34 mm
(mean 2.25 mm). N = 4–6.
Wings.
Male. Tegmina long, almost reaching the abdominal end, apex asymmetrically rounded, with indistinct venation (
Fig. 19H
); hindwings reduced, but well set off, scarcely longer than metanotum. Female. Tegmina lobiform, rounded broadly triangular, slightly surpassing the mesonotum; hindwings missing (
Figs.
19I
, N
).
Male structures.
Tergites.
T5-6 laterally at the anterior border with an extended but shallow excavation (
Figs. 19B, C
), mesally with a ventral deflection, especially strongly realized in the latter, thus forming a kind of a shallow gutter on the dorsal surface of the abdomen. T7 (
Figs. 18
F–H, 19D). Anterior border mesally produced, preglandular margin laterally very extended and well set off from the lateral parts of the anterior margin of T7, latero-posterior corners not produced, transversal ridge only partly indicated. Glandular pit large but shallow, extending over the mesal and anterior half of the tergite; bottom forming an anteriorly declining plane laterally and anteriorly bordered by a thin wall increasing in height towards anteriorly; bottom of pit mesally with a low longitudinal ridge, on both sides of the ridge at two different levels with a circular hole. Two separate anterior pouches present, consisting of branched tubes increasing in diameter towards their opening on both sides of the longitudinal ridge near the anterior border of the pit. Tubes near the opening interiorly with long bristles, with their straight and unspecialized tip partly reaching into the pit. Glandular pores in high density on the preglandular margin of T7 (
Fig.18G
), much less dense also on T9. Spatular bristles present on T3–7 (
Figs. 18E, J
). Posterior border of T10 mesally with a rather wide excavation (
Figs. 19G
,
20 D
).
S9
(
Fig. 19K
). Right latero-posterior corner produced, obliquely cut, left corner broadly rounded, posterior border in between slightly concave, left and right border almost parallel, the left slightly convex, the right slightly concave, towards the anterior lobe angularly produced.
Hook (
Figs. 19J, L
). Apical end of shaft on the left with a rounded bump, trough rather deep, scarcely narrowing towards basally; neck short with a rather long well sclerotized ribbonlike velum; claw more or less regularly curved, with pointed tip; beak extremely long, occupying about half of the claw length, keel at the external margin of the claw heightened to a triangular sail.
Colouration.
Variable.
Male
(
Figs. 19
A–G, H, M). Tegmina transparent, with a broad, towards the apex narrowing dark (brown) band, legs and antennae ochre, margins of thoracal nota transparent, remaining parts of nota either completely dark, or variously lightened to ochre, often a broad horseshoe-shaped dark marking remaining, or nota completely ochre; tergites usually completely dark, occasionally with only weak transversal lightenings at the level of the transversal ridge.
Female
(
Figs.
19I
, N, O
). Tegmina transparent, posteriorly with a large dark marking, colouration of nota similar as in male, abdominal tergites anteriorly dark, posteriorly ochre, sternites dark with broad ochreous lateral margins.
Distribution.
Restricted to the highest mountain of Fuerteventura (Mt. Jandia), situated on the Peninsula of Jandia in the SW of the island.
