S t a t u s: WARNCKE (1974) described Andrena tiaretta from Morocco, Algeria, Libya, and Egypt. In the Warncke collection of Linz, the holotype (male) and 29 paratypes (14♀♀, 15♂♂) were deposited (BLANK & KRAUS 1994, KRATOCHWIL 2015). The distribution area of the whole set of specimens (20♀♀, 23♂♂) covers a large area from southern Spain, Morocco, Algeria, Libya, Egypt, and Israel, to western Syria and (with one specimen) to northern Iran. In a revision with morphological and morphometric methods ( KRATOCHWIL 2015), the specimens of Spain, Morocco, and Algeria could be assigned to A. tiaretta WARNCKE, 1974 (holotype: 1♂; paratypes: 6♀♀, 9♂♂), but the eastern populations were described as a new species: in the case of Lybia as A. cyrenaica KRATOCHWIL, 2015 , and in the case of Israel and Syria as A. orientalis KRATOCHWIL, 2015 .
F o r m e r d e s c r i p t i o n s: According to WARNCKE (1974) the species is characterised as follows (translated from German): ‘Females with the clypeus more flattened, completely shagreened, hence dull, evenly punctured, with with impunctate line; mesonotum clearly shagreened, dull, slightly finer punctured; central area of the propodeum granuled shagreened, only on the basal half with rugulae; distal part almost grainy; tergites hammer-like shagreened, only laterally slightly punctured. Males similar to females, 2 nd flagellomere much longer than the 4 th; the following flagellomeres square; tergites with no significant depression zones.’
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. tiaretta is characterised by the following specific features:
F e m a l e: Colour. Head: flagellum dorsal brown, ventral light brown ( Figs. 22a, c, d View Fig ). Mesosoma: tibia mostly black (dark brown), basitarsus mostly reddish-brown, mediotarsi yellowish-reddish ( Fig. 22a View Fig ); wings light brownish toned, veins yellowishreddish brown ( Fig. 22a View Fig ); pterostigma yellowish, brown marginated ( Fig. 22a View Fig ). Metasoma: T1-4 black with reddish-brown depression zone ( Fig. 22a View Fig ); T5 reddish-brown.
Pubescence. Head: clypeus and supraclypeal area with white, not dense hairs; paraocular area with white hairs ( Fig. 22d View Fig ), no dark hairs between subantennal socket and facial fovea; scapus and antennal socket with dorsal longer and ventral shorter white hairs ( Fig. 22c View Fig ); genal area with white (67%) ( Fig. 22c View Fig ) or white-yellowish hairs (33%); facial fovea in the upper part with reddish hairs ( Fig. 23a View Fig ), in the lower part with white hairs ( Fig. 22d View Fig ). Mesosoma: mesoscutum and scutellum with white-yellowish hairs, laterally in the front with longer hairs ( Fig. 22e View Fig ); mesepisternum with white hairs; propodeal corbicula with some white hairs and some hairs in the centre; trochanteral and femoral flocculus with white hairs; tibial scopa dorsally, dorsobasally and ventrally with white hairs ( Fig. 23e View Fig ). Metasoma: tergites scarcely hairy, T2 and T3 (T4) with fragmentary white hair bands ( Fig. 22f View Fig ); T4 with row of hairs between tergite and tergite depression ( Fig. 22f View Fig ); T5 laterally with yellowish-white hairs, in the centre with yellowish or yellowish-reddish hairs ( Fig. 22f View Fig ); T6: with brown hairs.
Structure. Head: clypeus slightly convex with fragmented (50%) ( Fig. 23b View Fig ) or without impunctate line (50%), slightly shagreened, denser shagreened in the front, slightly dull, deeper punctured (PD: 14-28 μm, PDI: 14-42 μm) ( Fig. 23b View Fig ); labrum process liguliformtrapezoidal ( Fig. 23b View Fig ), top rounded, partly thickened, laterally on the top more or less oblique. Mesosoma: deeper and denser punctured, especially in the front (PD: 14-28 μm); propodeum clearly rugose in two third of the area and in dorsoventral area, long basal lamina, other area fine-grained shagreened ( Fig. 23d View Fig ). Metasoma: tergites rough hammertone-like shagreened and shiny; shallow and very scattered but not clearly punctured (PD: 14-28 μm) ( Fig. 23f View Fig ), T1 with very slight stepped depression zone, T2-T4 with deeper depression zones ( Fig. 22f View Fig ).
M a l e: similar to female with following differences:
Colour. Head: distal half of the mandible not or partly reddened; flagellum brown ( Figs. 24a, c, d View Fig ). Mesosoma: wings light toned ( Fig. 24a View Fig ); pterostigma yellowish (80%), yellowish-reddish (13%) ( Fig. 24a View Fig ), reddish (7%); all reddish-brown marginated ( Fig. 24a View Fig ).
Pubescence. Head: supraclypeal area with white hairs (67%) ( Figs. 24c, d View Fig ) or with some brown hairs (33%); scapus and antennal socket with dorsal longer white-yellowish hairs (71%) or with dorsal longer white hairs (29%) ( Fig. 24d View Fig ), no difference between dorsal or ventral side; genal area with long white-yellowish hairs. Mesosoma: mesoscutum and mesepisternum with white-yellowish hairs. Metasoma: scarcely hairy ( Fig. 24e View Fig ), T2-T3 with laterally longer white hairs, no distinct hair bands (63%) ( Fig. 24e View Fig ) but with fragmentary rows of hairs between the tergite and the tergite depression or with fragmentary white hair bands (37%); T5, T6 with white hairs, slightly yellowish; ST 8 with long white-yellowish hairs at the end.
Structure. Head: vertex above the ocelli narrow, as wide as half of the ocellar diameter (60%) ( Fig. 24d View Fig ) or as a ocellar diameter (40%); clypeus deeper punctured (PD: 28-38 μm, PDI: 14-32 μm) ( Fig. 25b View Fig ), labrum process trapezoidal, ends left and right side slightly thickened ( Fig. 25b View Fig ). Mesosoma: deeper and denser punctured (PD: 14-28 μm) ( Fig. 25c View Fig ), propodeum clearly rugose in the whole area, with short basal lamina ( Fig. 25d View Fig ); Metasoma: T1 slightly carinate, tergites very shallow and very scattered but not clearly punctured (PD: 14 μm) ( Fig. 25e View Fig ).
D i s t r i b u t i o n: The distribution of this species covers Spain, Morocco, and Algeria ( KRATOCHWIL 2015).
