S t a t u s: COCKERELL (1922) described A. wollastoni , analysing specimens from Madeira Island and Porto Santo. Until 2013, A. wollastoni had been reported for both islands ( FELLENDORF et al. 1999, KRATOCHWIL et al. 2008). Differing in numerous morphological and morphometric characteristics from A. wollastoni (Madeira Island), A. dourada was described by KRATOCHWIL & SCHEUCHL (2013) as a new species and endemic to Porto Santo. A single female specimen (collected by Cockerell’s wife, W. Porter Cockerell, in 1921 from Porto Santo) was mentioned in the description of COCKERELL (1922). This specimen belongs to the syntype series and is deposited in the USNM, designated as a paratype of A. dourada (KRATOCHWIL 2018) . Photos of the specimen and of the labels were published in KRATOCHWIL (2018).

D i a g n o s t i c q u a l i t a t i v e f e a t u r e s: Inadditiontothemorphological characteristics that are typical for the taxa of the A. wollastoni group, A. dourada is characterised by the following specific features:

F e m a l e: Colour. Head: flagellum black (dark brown) (74%) or black (26%) ( Figs. 11a, c, d ). Mesosoma: femur, tibia, and basitarsus black (dark brown) ( Fig. 11a ); mediotarsi reddish-brown ( Fig. 11a ); wings brownish toned, veins reddish-brown ( Fig. 11a ); pterostigma dark yellowish or reddish-brown ( Fig. 11a ). Metasoma: T1-4 black with black to dark reddish-brown depression zone; T5 depression zone reddish-brown.

Pubescence. Head: clypeus and supraclypeal area with white-yellowish hairs ( Fig. 11d ), paraocular area with white-yellowish hairs ( Fig. 11c, d ) and with some few brownish hairs between subantennal socket and the facial fovea; the scapus and the antennal socket with dorsal longer brownish and with ventral shorter yellowish hairs ( Fig. 11c ); genal area with white-yellowish hairs ( Fig. 11c ); facial fovea in the upper part with brownish hairs, in the lower part with white-yellowish hairs ( Fig. 11d ); vertex behind the ocelli with some longer white-yellowish hairs ( Fig. 11c, d ). Mesosoma: mesoscutum and scutellum with yellowish hairs, laterally with longer hairs ( Fig. 11a, e ); mesepisternum with white-yellowish hairs; propodeal corbicula with yellowish-white hairs and with some hairs in the centre; trochanteral and femoral flocculus with yellowish-white hairs; tibial scopa dorsally with yellowish-white hairs, dorsobasally with reddish-brown hairs, ventrally with yellowishwhite hairs ( Fig. 12e ). Metasoma: tergites scarcely hairy; T2 and T3 (T4) with lateral yellowish-white, fragmentary open hair bands (dense rows of hairs); T4 with row of hairs between the tergite and the tergite depression but T2-T4 with fragmentary rows of hairs between the tergite and the tergite depression; T5 laterally with dense white or whiteyellowish hairs, in the centre with reddish-brownish hairs reaching to the pygidium, T6 with brown hairs.

Structure. Head: clypeus convex without impunctate line, clearly shagreened, slightly dull, shallow and more or less densely punctured (PD: 28 μm, PDI: 14-42 μm) ( Fig. 12b ), labrum process liguliform (61%), liguliform-trapezoidal (26%) ( Fig. 12b ), trapezoidal (11%) or triangular (2%), slightly rounded on the top, partly thickened, laterally on the top more or less parallel. Mesosoma: scattered punctured with very shallow punctures, especially in the front (PD: 14 μm) ( Fig. 12c ); propodeum slightly rugose ( Fig. 11f ). Metasoma: tergites hammertone-like shagreened and shiny; shallow and very scattered but not clearly punctured (PD: 14 μm); T1 no depression zone or only with a slight depression zone, T2-T4: with deep depression zones.

M a l e: similar to female with following differences:

Colour. Head: distal half of the mandible not reddened; flagellum black (Fig. 13a); wings brownish toned; pterostigma brown.

Pubescence.Head: clypeus with white-yellowish hairs but not with darker hairs at the base (Fig. 13a); genal area in the upper part with brownish hairs, in the lower part with white hairs; paraocular area with white-yellowish hairs and with some brownish hairs near the subantennal socket (Fig. 13a); scapus and antennal socket with dorsal longer and ventral shorter yellowish hairs (Fig. 13a). Mesosoma: mesoscutum and scutellum with white-yellowish hairs (Fig. 13b); mesepisternum with white-yellowish hairs. Metasoma: base of T1 with some yellowish-white hairs, scarcely hairy in the centre, T2-T4 depression zones with lateral yellowish-white and very fragmented hair bands (dense rows of hairs); T5, T6 with long yellowish-white hairs; ST 8: with long white-yellowish hairs at the end.

Structure. Head: vertex above the ocelli narrow, as wide as the ocellar diameter; clypeus shallow and denser punctured (PD: 28 μm, PDI: 14-28 μm) (Fig. 13a); labrum process trapezoidal, emarginated (75%) or not emarginated (25%), ends left and right side thickened. Mesosoma: very scattered punctured (PD: 14 μm) (Fig. 13b); propodeum rugose; Metasoma: T1 slightly carinate, tergites very scattered punctured (PD: 14 μm).

D i s t r i b u t i o n: Andrena dourada occurs in different parts of Porto Santo, from sea level to 340 m a.s.l. (see the map in KRATOCHWIL & SCHWABE 2018b). Given to its small population sizes in a small distribution area, this endemic species should be ranked ‘vulnerable’ ( IUCN 2019).

F l i g h t p e r i o d: There were detections from January to April, but there are not enough data.
