745633B1743B5FEAA6A7DFD7AF5DC48F.taxon	diagnosis	Diagnosis. The new species Andrena culucciae can easily be recognized as a Plastandrena due to its distinctly widened and curved hind tibial spur at the base, the rugose areolate propodeal triangle, the rounded pronotum and coarsely punctate terga. It is structurally very similar to the other taxa within the A. pilipes / nigrospina complex because of its large size, dark body, dense network of raised rugosity on the dorsolateral faces of the propodeum and clypeus with large and dense punctations. Andrena culucciae differs mainly from Andrena pilipes s. s. and A. pilipes f. iliensis in the male sex by a longer genital capsule and broader penis valves at the base (Figs 5 – 7), as well as the translucent marginal zones of T 2 - T 5 (Fig. 8), which also distinguishes it from A. nigrospina. Females can be distinguished based on the predominant coloration of the setae on the hind legs: in A. culucciae, the setae on the femur are white and the tibial scopa is brown, in A. pilipes f. iliensis both femoral setae and tibial scopa are black, while in A. pilipes and in A. nigrospina both are white (Fig. 9). Further morphological comparisons between A. culucciae, A. pilipes and A. pilipes f. iliensis are reported in Table 2.	en	Annessi, Matteo, Riccieri, Alessandra, Di Giulio, Andrea (2025): A new species of Andrena (Hymenoptera, Andrenidae) from northern Sardinia (Italy).

745633B1743B5FEAA6A7DFD7AF5DC48F.taxon	description	Description. Male (Fig. 10). Body length: 12 – 13 mm. Head. Black, 1.2 times wider than long (Fig. 10 B). Ocelloccipital distance slightly greater than lateral ocellar diameter. Paraocular areas depressed, both frons and paraocular areas with longitudinal wrinkles (Fig. 10 B). Clypeus domed, slightly shiny with dense and large punctures, without an impunctate central line (Fig. 10 B). Labral process trapezoidal, apex emarginate. Mandibles slightly crossing apically with sparse setae along outer margin, bidentate; apical tooth longer than preapical tooth; maxillary palpi with six segments, labial palpi with four segments. Gena moderately broad, about equal in width to compound eye. Vertex and face with whitish and brownish setae (Fig. 10 B). Antenna dark, A 3 slightly shorter than A 4 (Fig. 10 B). Mesosoma. Scutum and scutellum irregularly punctate, with punctures larger and sparser medially. Pronotum rounded laterally, without humeral angle. Episternum and lateral propodeal surface reticulate, propodeal triangle strongly carinate with internal surface rugose-areolate. Scutum and scutellum with moderately long whitish setae, episternum and propodeum with brownish setae (Fig. 10 A). Legs dark, tarsal claw light brown, general pubescence dark brown, lighter on tarsal segments (Fig. 10 A, C). Wings brownish, venation dark brown and stigma light brown and nervulus slightly antefurcal; tegulae brown with surface rugose (Fig. 10 A). Metasoma. Terga dark and regularly punctate, punctures separated on average by 2 puncture diameters (Fig. 10 A). Disc of T 1 with sparser punctation, marginal zones of T 2 - T 5 slightly depressed and translucent (Fig. 10 A). T 1 - T 4 with very sparse short brown setae, last tergites with longer and darker hairs. Pygidial plate absent. S 7 deeply emarginate apically with lateral lobes hairy. S 8 hairy, slightly emarginate apically (Fig. 10 F). Genitalia elongate, gonocoxae with clearly produced apical teeth, these diverging slightly; gonostyli with apical spatulate parts elongate and parallel margins (Figs 6 A, 7 A, 10 D, E). Penis valves broad at the base (Figs 6 A, 7 A, 10 D), progressively tapering to the apex (Fig. 7 A). Volsella transverse, with rounded outer margins, and with both cuspis and digitus well developed (Figs 7 A, 11 A). Digitus curved, subparallel to the cuspis, basoventrally fused with the basivolsella, and with a bulged apex (Figs 7 A, 11 A, C). Cuspis triangular and spatulate, with a rounded apex and numerous erect setae of different lengths (Fig. 11 C). Cuneiform tooth-like cuticular structure, obliquely truncate and laterally directed, located in the ventral apical part of the digitus and the dorsal subapical part of the cuspis (Fig. 11 C). Basivolsella bulged, with numerous elongate setae (approximately 20, Fig. 11 A). Female (Fig. 12). Body length: 14 – 16 mm. Head. Black, 1.2 times wider than long (Fig. 12 B). Ocelloccipital distance slightly greater than lateral ocellar diameter. Fovea uniformly depressed along entire length, with lower margin ending distinctly below antennal insertion (Fig. 12 B). Frons with longitudinal wrinkles (Fig. 12 B). Clypeus, gena, maxillary and labial palpi as in male, labral process trapezoidal but without apical emargination. Mandibles slightly crossing apically with sparse setae along outer margin, unidentate. Subgenal coronet present and well-developed. Fovea, vertex and face with brown setae (Fig. 12 B). Antenna dark, A 3 slightly exceeds A 4 + 5, shorter than A 4 + 5 + 6 (Fig. 12 B). Mesosoma. Scutum, scutellum, pronotum, episternum, propodeum and propodeal triangle as in male. Scutum and scutellum with moderately long black and dark brown setae, episternum and propodeum with brownish setae (Fig. 12 A). Propodeal corbicula incomplete, possessing only a dorsal fringe; internal surface mostly glabrous, with very sparse setae. Legs dark, with tarsal claw light brown; fore and middle legs with general pubescence dark brown, lighter on tarsal segments; hind legs with white hairs on femur and tibial scopa predominantly composed of brown hairs (Figs 9 A, 12 A, C). Wings and tegulae as in male but browner (Fig. 12 A). Metasoma. Terga entirely dark, punctation similar to that of the male (Fig. 12 A). Pubescence of T 1 - T 4 as in male, apical fringe of T 5 and hairs flanking pygidial plate dark brown (Fig. 12 A). Pygidial plate V-shaped with round apex and a distinct raised internal triangle; internal surface rough.	en	Annessi, Matteo, Riccieri, Alessandra, Di Giulio, Andrea (2025): A new species of Andrena (Hymenoptera, Andrenidae) from northern Sardinia (Italy).
