Description. Total length 4.4 (3.4–5.1) mm, width 1.4 (1.1–1.7) mm. Body ( Fig. 16 ) small, relatively short, 3.13 (3.00–3.29; n = 3) times as long as pronotum at base, flattened, without dorsal curvature; coppery-bronze with copper or violet sheen; pronotal sides with large basal and smaller anterior yellow maculae; elytra mainly yellow with brown markings, without metallic sheen; elytral markings variable, more or less reticulate; tibiae and tarsi yellowish; body dorsally covered with short, recumbent and semierect, white and brownish setae, ventrally with longer recumbent white setae.

Head broad, flattened when seen from above; frons slightly convex, without medial line or depression, with weakly curved or nearly straight, markedly diverging sides. Vertex 1.95 (1.91–2.00) times as wide as transverse diameter of eye and 1.15 (1.10–1.20) times as wide as frons above antennal sockets. Clypeus rather narrow, with broad, shallow, arcuate medial emargination anteriorly. Frons with pseudoalveolate sculpture of big, deep simple punctures without inner structures; intervals about half the diameter of puncture, smooth; covered with short, semierect and recumbent white and brownish setae. Antennae expanded from antennomere 4 in both sexes; in male long, 2.30, in female 1.77 times as long as vertical diameter of eye; in male antennomere 2 elongate-oval, slightly swollen; antennomere 3 elongate, slender, thin, slightly longer than 2nd; antennomere 4 abruptly expanded, triangular, slightly longer than wide; distal antennomeres 4–10 triangular, nearly 1.5 times longer then wide; antennomere 11 missing; in female antennomere 3 slightly expanded apically; antennomere 4 triangular, slightly longer than wide; antennomeres 5–10 triangular, slightly longer than wide; antennomere 11 shortly oval.

Pronotum ( Fig. 16 ) moderately convex, 1.36 (1.31–1.40) times as wide at base as long, widest at posterior third; anterior of widest point sides longer, converging toward anterior angles, posterior of widest point sides shorter, converging towards posterior angles. Аnterior margin feebly bisinuate, slightly produced at middle, basal margin straight. Lateral carina fine, usually not reaching anterior corners, interrupted or lacking. Pronotal surface regularly convex, without medial depression or line; prescutellar fossa poorly marked or absent, lateral fossae punctiform, inconspicuous. Pronotum with uniform pseudoalveolate sculpture of deep simple punctures without inner structure, not forming concentric rugosities toward disc; covered with short, recumbent and semierect white and brownish setae. Pronotal sides with yellow to orange, bigger basal macula, sometimes reaching midlength, and smaller anterior macula.Anterior prosternal margin weakly emarginated, bordered with poorly marked groove; prosternum regularly convex, covered with punctate sculpture of small, deep punctures; meso- and metaventrites with same sculpture. Pronotal hypomeron bearing pseudoalveolate sculpture of simple punctures without inner structure.

Elytra ( Fig. 16 ) relatively short, 2.22 (2.06–2.31) times as long as wide at base, flattened; sides weakly expanded at humeri, slightly diverging or subparallel toward posterior third, then arcuately converging to regularly rounded apices. Subhumeral excision very shallow, poorly defined; epipleural serrations poorly marked, saw-like at posterior 1/3, apical teeth claw-like. Strial punctures big, deep, round, separate; discal striae visible up to base. Intervals narrow, nearly as wide as striae, except for wider lateral ones; 9 th interval elevated; intervals flat, with very small inconspicuous punctures; background finely shagreened, dull. Elytra mainly yellow with slightly contrasting brownish markings of reticulate Acmaeodera (Palaeotethya) rubromaculata type, formed by irregular longitudinal and oblique stripes and confluent maculae, occasionally strongly reduced; covered with short, semierect, uni- and confused biseriate, white or white and brownish setae.

Legs: Femora black and brown, tibiae and tarsi yellowish ( Fig. 16 ); metacoxal plates with posterior margin feebly emarginated, without lateral tooth. Tibiae slender, not widened toward apices; metatibiae bearing comb of brownish setae externally. Tarsomeres subequal, short; tarsomere 5 slender; tarsal pads poorly developed on tarsomeres 1–3, each larger toward apex. Tarsal claws long, curved, with internal tooth at apical third in both sexes.

Abdomen bronze with copper sheen; covered with uniform pseudoalveolate sculpture of big, dense, simple punctures and recumbent white setae. Anal ventrite in male short, transversely depressed, widely arcuate and slightly emarginate apically; in female widely arcuate and slightly deflected apically.

Male: Aedeagus as in Figs. 26, 27 . Penis short, expanded medially; lamina short, triangular, widened toward base; apical apodeme wide.

Female: Ovipositor not examined.

Differential diagnosis. Acmaeodera (Acmaeotethya) hadiboe sp. nov. differs from A. (A.) kabateki sp. nov. and A. (A.) socotraensis sp. nov. by lighter coppery-bronze body and lighter elytra, uniformly pseudoalveolate sculpture of head, pronotum and pronotal hypomeron, shallow subhumeral excision of elytra, yellowish tibiae and tarsi, and, particularly, structure of the male genitalia ( Figs. 24–29 ). Additionally, A. (A.) hadiboe sp. nov. differs from A. (A.) kabateki sp. nov. by a shorter body (3.13 times as long as pronotum at base), reduced pronotal markings, slightly contrasting and light elytral markings; from A. (A.) socotraensis sp. nov. it differs by its lighter metallic body coloration, lack of dorsal curvature, frontal sides diverging less toward vertex, antennae of male longer, pronotal margins without distinct lateral projections, elytral serrations poorly marked, and semierect pilosity of pronotal disc, elytra and abdomen.

Etymology. The specific epithet derives from the name of the capital of Socotra Island, Hadibo.

Host plant. Zizyphus spina-christi (L.) Dest. ( Rhamnales : Rhamnaceae ). One specimen has been reared by P. Kabátek from the same host plant at the same locality (Hadibo env.) as two paratypes of A. kabateki sp. nov.

Distribution. Yemen: Socotra Island.
