Andrena lineolata WARNCKE, 1968 View in CoL

H o l o t y p e: 1♀ Tenerife, El Portillo, 18.06.1933, collector unknown.

P a r a t y p e s: 1♂ Tenerife, Monte de las Mercedes , 02.03.1952, leg. Fernandez ; 1♀ Tenerife , La Laguna, 07.05.1928, collector unknown ; 6♀♀, 11♂♂ Tenerife, Las Cañadas , 17.05.1960, leg. Lundblad ; 1♀, 1♂ Tenerife, Teide, Las Cañadas , 20.05.1947, leg. Lindberg ; 1♂ Tenerife, Izaña , 04.06.1922, leg. Cabrera ; 1♀ Tenerife Las Cañadas , 16.06.1903, collector unknown ; 1♀ Tenerife , El Portillo, 18.06.1933, collector unknown ; 2♀♀, 1♂ Tenerife, Cumbre Roque de Caramuyo , 20.- 21.06.1923, 2202 m, collector unknown ; 1♀ Tenerife , El Portillo, 02.07.1933, collector unknown .

S t a t u s: WARNCKE (1968) described A. lineolata as endemic to Tenerife on the basis of 30 specimens (1♀ holotype; 14♀♀, 15♂♂ paratypes). Besides the holotype, 8♀♀ and 6♂♂ of paratypes are deposited in the OLML (see also BLANK & KRAUS 1994). The type specimens in the OLML are all provided with a determination label from Warncke and were analysed in the frame of this study. (holotype: female, El Portillo, 18.06.1933, collector unknown). One paratype of A. lineolata (1♂ Tenerife, Las Cañadas, May 1960, leg. Lundblad) is deposited in the MNCN (1♂ of the same serie, also a paratype, is deposited in the OLML). Three females and one male (all paratypes, with the label Tenerife, Teyde, Cañadas, 20.05.1947, collected by Lindberg) are deposited in the ZMUH and characterised by the labels ‘Mus. Zool H: Fors, Spec. typ. No 5525, 5526, 5532, 5533’. Remarkably, only one female is mentioned in the description of WARNCKE (1968). The whereabouts of 10 type specimens (2♀♀, 8♂♂) could not be clarified.

F o r m e r d e s c r i p t i o n s: WARNCKE (1993) compared the morphological features of A. lineolata to those of A. wollastoni (translated from German) as follows:

F e m a l e: hairy gray-white pubescence, only slightly denser and longer hairs than in A. wollastoni ; tergites 2-4 with open white and narrow hair bands; clypeus clearly bulging, somewhat snout-shaped, slightly coarser and more densely punctured, puncture distance 1-1.5 of the puncture diameter; labrum triangular; thorax in A. wollastoni fine scattered and hardly recognizable punctured; strongly grainy shagreened; in A. lineolata similar, but denser (1-2 puncture of the diameter distance) and deeper punctured, therefore punctures clearly visible; fine-grained and shagreened but weaker in microsculpture, therefore weakly shiny; scutellum more strongly punctured and not shagreened in the centre, therefore shiny; propodeum rugose at the base, distal part almost grainy without rugulae; sculpture of the abdomen similar to A. wollastoni , mesosoma seems broader than in A. wollastoni .

M a l e: with lighter hairs, even the head only next to the antenna base with some interspersed black hairs, otherwise lightly haired; thorax puncture also denser and deeper, scutellum shiny, genitals very similar to A. wollastoni .

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. lineolata is characterised by the following specific features:

F e m a l e: Colour. Head: flagellum dorsal dark brown, ventral light brown (78%) or dorsal black, ventral brown (22%) ( Figs. 18a, c, d View Fig ). Mesosoma: femur, tibia, and basitarsus brown ( Fig. 18a View Fig ); mediotarsi yellowish-reddish; wings light brownish toned ( Fig. 18a View Fig ), veins yellowish-reddish brown; pterostigma yellowish, brown marginated ( Fig. 18a View Fig ). Metasoma: T1-4 black with reddish-brown depression zone ( Fig. 18a View Fig ); T5 depression zone reddish-brown.

Pubescence.Head: clypeus and supraclypeal area with white but not dense hairs; paraocular area with white hairs, no brownish hairs between the subantennal socket and the facial fovea ( Fig. 18d View Fig ); scapus and antennal socket with dorsal longer white-yellowish hairs and ventral shorter white-yellowish hairs ( Fig. 18c View Fig ); genal area with white hairs; facial fovea with white hairs; vertex behind the the ocelli with some long white-yellowish hairs ( Fig. 18c View Fig ). Mesosoma: mesoscutum and scutellum with white-yellowish hairs, laterally in the front with longer hairs; mesepisternum with white hairs; propodeal corbicula with some white hairs and with some hairs in the centre; trochanteral and femoral flocculus with white hairs; tibial scopa dorsally and ventrally with white hairs, dorsobasally slightly reddish, distally with white hairs ( Fig. 19d View Fig ). Metasoma: tergites scarcely hairy, T2 and T3 (T4) with lateral white, fragmentary open hair bands (dense rows of hairs) ( Fig. 18a View Fig ); T4 with row of hairs between tergite and tergite depression; T5 laterally with yellowish-white hairs, in the centre with yellowish (yellowish-reddish) hairs ( Fig. 18a View Fig ); T6: brown hairs.

Structure. Head: clypeus strong convex with impunctate line ( Fig. 19a View Fig ), more or less shagreened ( Fig. 19a View Fig ), slightly dull, deeper punctured (PD: 14-28 μm, PDI: 28 μm) ( Fig. 19a View Fig ), labrum process triangular (50%) ( Fig. 19a View Fig ) or triangular-trapezoidal (50%), slightly rounded on the top, laterally more or less oblique. Mesosoma: deeper and denser punctured, especially in the front (PD: 14 μm) ( Fig. 19b View Fig ); propodeum rugose ( Fig. 19c View Fig ). Metasoma: tergites rough hammertone-like shagreened and shiny; shallow and very scattered but not clearly punctured (PD: 14 μm), T1 very slight stepped depression zone, T2-T4 with deeper depression zones ( Fig. 18a View Fig ).

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

Colour. Head: distal half of the mandible not or partly reddened ( Fig. 21b View Fig ); flagellum brown ( Figs. 20c, d View Fig ). Mesosoma: wings light toned ( Fig. 20f View Fig ); pterostigma yellowish in the centre, brown marginated.

Pubescence. Head: clypeus with white hairs but no dark hairs ( Fig. 21b View Fig ); genal area with long white hairs ( Fig. 21b View Fig ). Mesosoma: mesoscutum and mesepisternum with white hairs ( Fig. 20d View Fig ). Metasoma: base of T1 with some white-yellowish hairs, scarcely hairy in the centre, T2-T4 depression zones with laterally white strong fragmented hair bands (dense rows of hairs) ( Fig. 20f View Fig ); T5 with some yellowish hairs; T6 with yellowish and partly reddish hairs in the centre and laterally with yellowish-white hairs ( Fig. 20f View Fig ); 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 ( Fig. 20e View Fig ); clypeus larger, deeper, and denser punctured (PD = 14-32 μm); labrum process trapezoidal, emarginated (82%) ( Fig. 21b View Fig ), slightly emarginated (15%), ends left and right side (slightly) thickened ( Fig. 21b View Fig ). Mesosoma: deeper and denser punctured (PD = 14-28 μm); Metasoma: T1 slightly carinate, tergites very shallow and very scattered but not clearly punctured (PD = 14 μm).

D i s t r i b u t i o n: The main distribution of this endemic species is concentrated in the area Las Cañadas/Teide at altitudes of about 2000 m a.s.l to 3300 m a.s.l. (observations of LARA- ROMERO et al. 2019 about 3300 m a.s.l.). In the literature, some specimens were also detected in the Anaga area at lower altitudes (500-1000 m a.s.l., data from 1928 and 1952); HOHMANN et al. (1993). It was not possible to to prove whether there was any confusion with A. a. acuta . Despite intensive screening in March and May, we did not find any individual of A. lineolata in the Anaga area.

F l i g h t p e r i o d: According to HOHMANN et al. (1993), LARA- ROMERO (2019) and own data the flight period is from April to July.
