Andrena ( Notandrena) cazorlae Wood sp. nov.

Type material.

Holotype: Spain • 1 ♀; Jaén, Sierra de Cazorla, La Cabrilla ; 37.9314°N, - 2.7806°W; 31 May 2022; A. Núñez leg.; RMNH; RMNH.INS.1715577 .

Description.

Female. Body length: 9 mm (Fig. 9 A ). Head: Dark, 1.4 times wider than long (Fig. 9 B ). Clypeus weakly domed, fore margin upturned, surface microreticulate, weakly shining apically; surface with obscure punctures, punctures separated by <0.5–1 puncture diameters. Process of labrum trapezoidal, 2 times wider than long, anterior margin narrowly but distinctly emarginate. Gena slightly exceeding width of compound eye; ocelloccipital distance equalling diameter of lateral ocellus. Foveae dorsally occupying slightly> ½ space between compound eye and lateral ocellus (Fig. 9 C ), slightly narrowing ventrally at level of antennal insertions; foveae filled with dark brown hairs, becoming lighter ventrally. Face and gena covered with short white hairs, becoming longer and light brown on vertex. Antennae dark, A 5–12 slightly ventrally lightened by presence of greyish-orange scales; A 3 equalling A 4 + 5, A 4 sub-square, slightly wider than long.

Mesosoma: Scutum densely punctate, punctures typically separated by 0.5–1 puncture diameters, surface finely microreticulate, dull (Fig. 9 D ). Scutellum more sparsely punctate, punctures separated by 0.5–4 puncture diameters over majority of disc; surface finely shagreened, weakly shining. Pronotum with weak humeral angle. Mesepisternum and dorsolateral parts of propodeum microreticulate overlain by network of dense and fine raised rugosity, surface dull. Propodeal triangle broad, laterally delineated by fine carinae, internal surface with fine network of raised rugae covering majority of surface. Mesepisternum with white finely plumose hairs, hairs becoming golden-brown on scutum. Propodeal corbicula incomplete, composed of whitish plumose hairs, internal surface with long simple hairs. Legs dark basally, tarsi and hind tibiae partially lightened orange, pubescence whitish. Flocculus complete, composed of white plumose hairs; femoral and tibial scopae composed of pale simple hairs, tibial scopa with dorsal and ventral fringes long, dorsal fringe not noticeably shorter than ventral fringe (Fig. 9 E ). Hind tarsal claws with small inner tooth. Wings hyaline, stigma and venation dark brown, nervulus interstitial.

Metasoma: Tergal discs dark, apical margins with rims narrowly lightened hyaline-brown (Fig. 9 F ). T 1 with disc moderately punctate, punctures separated by 1–3 puncture diameters; discs of T 2–4 densely punctate, punctures separated by 0.5–1 puncture diameter, punctures becoming sparser on marginal areas. Tergal surface finely shagreened, weakly to strongly shining depending on puncture density. Tergal discs with obscure short white hairs, not obscuring underlying surface, marginal areas of T 2–4 with narrow apical hairbands composed of white hairs, broadly interrupted on T 2, nearly complete but abraded on T 3, and complete on T 4. Apical fringe of T 5 and hairs flanking pygidial plate golden-brown, becoming white laterally. Pygidial plate rounded triangular, medially very subtly depressed and shallowly and obscurely punctate.

Male. Unknown.

Diagnosis.

Andrena cazorlae can be recognised as part of the subgenus Notandrena Pérez, 1890 due to the short and broad head (1.4 times wider than long), pronotum with a humeral angle (weak and challenging to see), the non-metallic integument, and lack of any other distinctive characters takes it to couplet 177 in the female key of Wood (2023). It can be separated from all Iberian Notandrena due to the combination of dense scutal punctures (separated by 0.5–1 puncture diameters, but not contiguous; contiguous in A. griseobalteata Dours, 1872 ), facial foveae broad and occupying slightly> ½ the space between the compound eye and lateral ocellus (narrower in all comparison species), body length of 9 mm ( 10–11 mm in A. langadensis albipila Warncke, 1967 ), and hind tibia with the dorsal scopal hairs clearly exceeding the diameter of a lateral ocellus in length, not meaningfully shorter than the ventral hairs (these hairs around 1–1.5 times the diameter of an ocellus in A. pallitarsis Pérez, 1903 ).

Finally, due to the broad facial foveae it is similar to A. pontica Warncke, 1972 (southern Germany to eastern Turkey), but apart from the distinct geographical range, this species has the facial foveae broader (occupying ¾ of the space between the compound eye and lateral ocellus) and the scutellar punctures more uniformly dense, separated by 0.5 puncture diameters.

Etymology.

Taken from the name of the mountain range the Sierra de Cazorla in the genitive singular form, hence “ the Andrena of Cazorla ”.
