S t a t u s: COCKERELL (1922) described six syntypes of Andrena wollastoni from Madeira and Porto Santo, collected by T. V. Wollaston or some of his fellow collectors and deposited in the NHMUK. KRATOCHWIL (2018) designated one female specimen ( Fig. 26 ), characterised by Cockerell, with a type label as a lectotype; the five other specimens (also females) of the series were designated as paralectotypes. COCKERELL (1922) also characterised two further males also as types (collected by Rev. Alfred E. Eaton, Monte, Funchal, Madeira, 06.03.1902, at an altitude of about 11.000 feet). These males should be part of the Eaton collection and were determined by SAUNDERS (1903) as A. minutula, KIRB. These specimens should be deposited in the NHMUK ( COCKERELL 1922). The whereabouts of the male type specimens of the Eaton collection remain unknown (KRATOCHWIL 2018). The distribution area of A. wollastoni covers Madeira Island. In the context of the new description of A. dourada , A. wollastoni was described in detail in KRATOCHWIL & SCHEUCHL (2013) concerning status, former descriptions, up-to-date description, historical records, subgenus classification, distribution and habitat characteristics, and flight period (flower visiting behavior in KRATOCHWIL et al. 2019).

F o r m e r d e s c r i p t i o n s: The description of COCKERELL (1922) is based on some morphological features: ‘Female. – Like Andrena minutula KIRBY , but area of metathorax dull and granular, with sculptures hardly visible under a lens, mesothorax less punctured; stigma larger and darker. Male. – Recorded by E. Saunders from the Mount, Funchal (Eaton); the specimens are in the British Museum. He remarks that they are apparently minutula, a form with the mesonotum rugulose and with very distinct shallow punctures, with the long-haired face characteristic of the first brood.’ GUSENLEITNER & SCHWARZ (2002) give a more detailed description (translated from the German version): ‘Especially characteristic is the fine-grained, nearly unpunctured or weakly punctured mesonotum and the fine tongue-shaped labrum process (variation in subspecies). The central area of propodeum is large, mostly homogeneously grainy shagreened with centrally orientated weakly developed sutural structures. The tergite structure is very variable reaching from clearly shagreened to nearly unshagreened and therefore strongly shining. The depressions of tergite 3 and tergite 4 are clearly deepened. Some specimens show at the margins of tergite 1 the beginning of bar development. Males and females can be characterised by dorsal thorax structure. The smooth surface and borderline of the depressions are conspicuous. The genital structure is not complex similar to A. minutula but with some differences in the shape of gonostyli.’

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. wollastoni is characterised by the following specific features:

F e m a l e: Colour. Head: flagellum black (dark brown) ( Fig. 26a, c ). Mesosoma: tibia and basitarsus black (dark brown) (96%) ( Fig. 26c ), partly reddish-brown (4%); mediotarsi reddish-brown; wings brownish toned ( Figs. 26c ), veins reddish-brown; pterostigma dark yellowish or reddish-brown ( Fig. 26c ).

Pubescence. Head: clypeus and supraclypeal area with yellowish-white but not dense hairs ( Fig. 26d ); paraocular area with yellowish-white hairs ( Fig. 26d ), many brownish or black hairs between the subantennal socket and the facial fovea; scapus and antennal socket with dorsal longer brownish and ventral shorter yellowish hairs ( Fig. 26d ); genal area with yellowish-white hairs ( Fig. 26c ); facial fovea with brown hairs. Mesosoma: mesoscutum and scutellum with yellowish-brownish hairs, in some cases laterally some yellowish hairs; mesepisternum with yellowish-white hairs; propodeal corbicula with some yellowish-white hairs and some hairs in the centre; trochanteral and femoral flocculus with yellowish-white hairs; tibial scopa with yellowish-white hairs, dorsoventrally with dark brown hairs or hair tips ( Fig. 26e ). Metasoma: tergites scarcely hairy, T2 and T3 (T4) with laterally yellowish-white, fragmentary open hair bands (dense row of hairs) ( Fig. 26c ); T4 with row of hairs between tergite and tergite depression; T5 laterally yellowish-white hairs, in the centre reddish-brownish hairs reaching the pygidium ( Fig. 26c ); T6: dark brown hairs.

Structure. Head: clypeus convex without impunctate line, clearly shagreened, slightly dull, shallow punctured, more or less densely punctured (PD: 28 μm, PDI: 14-84[112] μm) ( Fig. 27d ), labrum process trapezoidal (86%), trapezoidal-liguliform (7%), liguliform (3.5%) or trapezoidal-triangular (3.5%); trapezoidal form slightly emarginated or emarginated with the ends left and right side thickened or the top rounded, laterally on the top more or less oblique. Mesosoma: shallow and very scattered punctured, denser punctured in the front (PD: 14 μm); propodeum slightly rugose in the basal centre and in dorsoventral area, with short basal lamina, other area fine-grained shagreened. Metasoma: tergites rough hammertone-like shagreened and shiny; shallow and very scattered not clearly punctured (PD: 14 μm), T1 not or very slight stepped depression zone ( Fig. 26a ), T2-T4 with deeper depression zones ( Fig. 26a ).

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

Colour. Head: distal half of the mandible not reddened; flagellum dark brown (56%) or black (44%). Mesosoma: wings light brownish toned; pterostigma brown (96%) or yellowish (4%).

Pubescence. Head: clypeus with yellowish-white hairs, but no dark hairs; genal area upper part with brownish hairs, lower part with long yellowish-white hairs. Mesosoma: mesoscutum with yellowish-brownish hairs, mesepisternum with yellowish-white (96%) or yellowish (4%) longer hairs. Metasoma: some short hairs, T2 and T3 no distinct hair bands, but rows of hairs between the tergite and the tergite depression, T2, T3 with fragmentary hair bands (52%) or without hair bands (48%); T5 and T6 with longer yellowish-white hairs; ST 8 with long yellowish hairs at the end.

Structure. Head: vertex above the ocelli narrow, as wide as half of the ocellar diameter; clypeus shallow and denser punctured (PD: 28 μm, PDI 14-28 μm), labrum process trapezoidal, emarginated, the ends left and right side thickened. Mesosoma: very shallow scattered punctured, especially in the front (PD: 14 μm), propodeum rugose, primarily in the centre and in the dorsolateral area, with short basal lamina, other area fine-grained shagreened. Metasoma: T1 slightly carinate, tergites shallow and very scattered but not clearly punctured (PD: 14μm).
