Remarks
Identification of female material from species close to A. gelriae is highly challenging without access to confidently determined comparative material. In Iberia, female A. gredana can be recognised by the dense punctures of the base of T2 (smooth to weakly and sparsely punctate in A. similis Smith, 1853 ),
faint punctures on the disc of T1 (strongly punctate in A. wilkella (Kirby, 1802)) , fore part of clypeus shiny ( Fig. 5 View Figs 4–11. 4–8 ), contrasting the central and basal areas which are dull (uniformly dull in other species), the sculpturing of the scutum ( Fig. 6 View Figs 4–11. 4–8 ), which is shagreened but centrally has a circular area where the shagreenation is comparatively weaker when viewed dorsolaterally (other species uniformly shagreened or with a clearly shiny central circular area), and the comparatively wide hair bands on the terga ( Fig. 7 View Figs 4–11. 4–8 ) that are complete on T2+3+4 (either much thinner, or not complete on T2 and/or T3),
Males are significantly easier to identify, and can initially be recognised by the length ratios of the antennal segments, being part of the group where A3 is equal to A 4 in length. In this group, the genitalia of A. gredana are highly distinctive, showing gonocoxa that diverge only slightly at their apexes, and with a penis valve that is clearly narrowed basally and widened to its maximum width centrally before tapering to its apex ( Fig. 8 View Figs 4–11. 4–8 ). This character allows separation from all other Iberian Taeniandrena . In fact, molecular data shows that this taxon is not closely allied to A. gelriae ( Fig. 1 View Fig ), and the divergent structure of the penis valve would support this conclusion when compared to the species allied to A. gelriae ( Figs 9–11 View Figs 4–11. 4–8 ). Given these differences and its phylogenetic placement, A. gredana is formally raised to species status.
Distribution
Central and northern Spain and Portugal ( Warncke 1976; Fig. 3 View Fig ). The distribution in Iberia is montane, and it may also occur in the French Pyrenees (see record from Huesca Province; Fig. 3 View Fig ), but no specimens have yet been reported from this region.
