Adult. Colouration of dry material. General body colour dark brown to black. Vertex green to brown yellowish, genal processes yellowish brown. Antenna yellowish brown with segments 3–6 each with black apex, segments 7 and 8 each with apical half black, and segments 9 and 10 entirely black. Thoracic dorsum dark brown yellowish to black with pronotum white to light brown, and 2 white spots on each side of mesoscutum. Forewing transparent, veins brown. Abdominal sclerites dark brown, intersegmental membranes white. Male proctiger brown yellowish with black apex, paramere light brown yellowish with black apex, subgenital plate light brown yellowish, sometimes black basally. Female terminalia yellowish brown. Structure . Body length 1.8–2.3. Vertex 0.6–0.7 times as long as broad. Genal processes 0.3–0.4 times as long as vertex. Antenna 2.6–2.8 times as long as head width.

Male terminalia as in Figs 76–78 . Proctiger 0.5–0.6 times as long as head width. Paramere 0.5 times as long as proctiger, with anterior and posterior margins slightly sinuate, digitiform apical process with posterior margin straight or slightly sinuate, forming a strongly sclerotised small, posteriorly directed tooth. Apical segment of aedeagus 1.1 – 1.2 times as long as paramere. Female terminalia as in Fig. 79 . Proctiger 0.7–0.8 times as long as head width; circumanal ring 0.3–0.4 times as long as proctiger. Measurements (in mm) (5 ♂, 6 ♀ ). Head width ♂ 0.49 – 0.54, ♀ 0.46 – 0.57; vertex length ♂ 0.17 – 0.20, ♀ 0.18 – 0.23; vertex width ♂ 0.27 – 0.30, ♀ 0.25 – 0.31; antenna length ♂ 1.28 – 1.40, ♀ 1.24 – 1.43; metatibia length ♂ 0.53 – 0.57, ♀ 0.48 – 0.58; forewing length ♂ 2.15 – 2.35, ♀ 2.55 – 2.84; forewing width ♂ 0.82 – 0.93, ♀ 0.99 – 1.14; male proctiger length 0.29 – 0.32; paramere length 0.14 – 0.16; distal segment of aedeagus length 0.17 – 0.19; female proctiger length 0.37 – 0.46; female anal ring length 0.14 – 0.15. Fifth-instar immature. Corresponding to the generic description but see comments below. Etymology. Named after the people of the Benahoritas, the first known inhabitants of La Palma. After the conquest of the Canary Islands by order of the Crown of Castile in the 15th century, the Benahoaritas were wiped out as an independent ethnic group through various measures taken by the conquerors. Host plant CI. Convolvulus floridus (Convolvulaceae) . Distribution CI. La Palma. Comments. Percyella benahorita differs from the other Percyella species in the shape of the paramere. The posterior margin of the paramere is more curved than in the other three species and the posterior margin of the apical process is slightly sinuate or straight, sometimes with a flat hump (slightly sinuate in P. canari , straight in P. gomerita and sinuate in P. guanche ). It also differs from the other species in its distribution in the Canary Islands , since it is only found in La Palma. No characters were found to separate the females and immatures of P. benahorita from the other Percyella species.
