Redescription of the Holotype of Agrilus albogularis perisi Cobos, 1986 ( nov. stat.)

Length: 4,3 mm.; whole body metallic green. Head: frons, in dorsal view, slightly rounded with indistinct medial depression, vertex convex and distinctly grooved; head sculpture consisting of irregular longitudinal wrinkles with short and sparse white pubescence, longer on basal frons above the clypeus. Antennae short, serrate from antennomere 4. Pronotum 1,4 times as wide as long, widest at anterior third; lateral pronotal margins slightly S­shaped narrowed from anterior third until its posterior pronotal right angles; anterior pronotal margin lobate medially; two depressions on pronotum, one in anterior half behind the middle of anterior margin and the second posterior, prescutellar, nearly indistinct; prehumeral keel short, slightly marked; pronotal sculpture consisting of transverse and very irregular curved wrinkles, somewhat concentric in anterior half; entire pronotum with very short white pubescence longer in lateral pronotal margins. Scutellum somewhat wider than long, with well developed transversal keel; anterior half with very fine microsculpture. Elytra 2,5 times as long as wide, slightly shorter than maximum width of pronotum; basal depressions deeply marked; elytra with homogeneous grainy sculpture and very short white, regularly distributed recumbant pubescence; humeral swellings marked; lateral margins slightly S­shaped, narrowed before their midlength; elytral apices feebly serrate and separately rounded; elytral suture elevated from the middle to the apex. Ventral surface of body with dense punctation; short, white pubescence; metasternum slightly grooved medially; anal sternite rounded apically. Legs slender and relatively long; first metatarsomere approximately of the same length than following two. Aedeagus short, 6,6 times as long as wide, parallel, narrowed behind middle; apical part of median lobe sclerotized with rounded truncate apex.

The male holotype of Agrilus perisi bears the following labels and data: [white label]: Casa de Campo Madrid, VI­1949, A. Cobos coll.; underside “sobre chopos” / [yellow label]: EX COLECCIÓN Dr. A. Cobos / [red label]: HOLOTYPUS A. COBOS / [white label]: Agrilus perisi nov. sp. holotypus A. Cobos det. 1979. The holotype of A. perisi is henceforth provided with a printed white label bearing following data: Agrilus albogularis perisi Cobos, 1986 / L. Arnáiz & P. Bercedo det. 2002.

Variation

Length: 4,3­6,1 mm., generally green metallic, some specimens with more or less golden green or golden areas. Prehumeral keel short, weakly marked or absent. Females more robust and with apical margin serration of elytra more evident.

Host plant

Except the holotype, which it seems was collected accidentally on Populus sp., all specimens examined were collected on Artemisia herba­alba , the suspected host plant of A. a. perisi .

Distribution

A. a. perisi is known from the following Spanish localities and provinces: Madrid (type locality), Jumilla in Murcia, Reinoso and Hornillos de Cerrato in Palencia and Peñaflor in Zaragoza.

Differential diagnosis

Agrilus albogularis perisi ( Fig. 1 [Habitus], fig. 2 [Aedeagus]) differs from the other subspecies present in the Iberian Peninsula Agrilus albogularis artemisiae and its closest ally Agrilus albogularis dalmatinus by the characters indicated in the table:
