DNA types (= paratypes): 1 ex., same data as for holotype, collector no.: 3188-AVE; GenBank: MN 627733 / 1 ex., E: Cádiz, Medina Sidonia, El Berrueco: Pistacia lentiscus , 36°26'22.4"N, 06°01'52.9"W, 21.12.2018, leg. Verdugo & Coello, collector no.: 3189-AVE; GenBank: MN 627734 , DNA deposited in Senckenberg Deutsches Entomologisches Institut , ( SDEI, Germany, Müncheberg) .

Total length 2.3 mm – 3.2 mm (excluding rostrum).

Colour: Body without metallic reflections. Dorsal surface of head, pronotum, scutellum and elytra ochraceousyellowish to pale orange, with apex of rostrum and suture of elytra slightly darker. Legs and antennae yellowish, but with antennal club and onychium blackish. Ventral surface with prosternum, mesosternum, lateral margins of metasternum, coxae and trochanters pale orange; disc of metasternum and abdominal sternites black.

Head: Eyes rounded, convex and prominent. Frons with robust and regular punctuation; punctures with white and elongate setae directed forwards. Rostrum about twice longer than pronotum, in dorsal view nine times longer than the width between antennal insertions. Sides of rostrum with white and short setae, 4 or 5 longer setae on the apex. Antennae inserted very close to base of rostrum; 1 st antennal segment as long as 2 nd; 3 th, 4 th and 5 th segments 1.5 times as long as 1 st; 6 th, 7 th and 8 th approx. as long as 1 st; last three antennal segments (9 th, 10 th and 11 th) forming a club as long as 3 th and 4 th combined.

Pronotum: Pronotum slightly shorter than its maximum width; in dorsal view basal margin about as wide as anterior margin, sides moderately rounded, maximum width behind middle; surface with long white setae, directed forwards, and with robust and regular punctuation; the space between punctures is equal to the diameter of a puncture.

Scutellum: Equilateral triangle-shaped.

Elytra: Elytra subovoid, 1.5 times longer than wide; presutural interstria elevated; punctuation not uniform, irregularly arranged, confluent close to the distal area; elytral pubescence double, consisting of reclinate, pale yellow setae (directed backwards) and sparse, blackish, erect setae (especially visible on the elytral margin).

Ventral surface: 1 st abdominal sternite as long as 2 nd and slightly shorter than 3 th + 4 th + 5 th combined; abdominal sternites with whitish pressed setae that are shorter than elytral setae.

Aedeagus / endophallus: See Fig. 1A .

Females: The females are somewhat bigger and equipped with a slightly longer rostrum than the males (see Fig. 1A vs. 1B). Spiculum ventrale of the female genitalia is presented in Fig. 2B .
