Not chosen as paratypes for A. g. palmae, because the locality of deposition is unknown, are 2♂♂

previously dedicated by WARNCKE (1968) as paratypes of A. wollastoni acuta for La Gomera (1♂

Isla de la Palma, 1907, leg. Santos ; 1♂ Supra El Paso, 600 m, 04.04.1950, leg. Lindberg).

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 A. gomerensis group, A. g. palmae nov.ssp. is characterised by the following specific features:

F e m a l e: Colour. Mesosoma: femur, tibia, and basitarsus black (dark brown) similar to A. g. gomerensis, but there are few specimens (10%) with partly reddish colour; mediotarsi reddish-brown similar to A. g. gomerensis, but in A. g. palmae nov. ssp. some specimens (14%) with brown colour. Metasoma: T1-4 black with reddish-brown; T5 depression zone reddish-brown.

Pubescence.Mesosoma: tibial scopa dorsally with slightly brownish hairs (A. g. gomerensis with brownish hairs), dorsobasally with reddish-brown hairs, tibial scopa ventral with yellowish-white hairs.

Structure. Head: with fragmented impunctate line (71%) or without impunctate line (29%), shallow more or less densely punctured (PD: 28 μm, PDI: 14-56 μm), labrum process triangular, rounded on the the top, laterally more or less oblique. Mesosoma: scattered punctured with very shallow punctures especially in the front (PD =14-28 μm).

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

Colour. Head: flagellum light brown in contrast to A. g. gomerensis brown (66%) or light brown (34%). Mesosoma: mediotarsi reddish-brown in contrast to A. g. gomerensis reddish-brown (66%) or brown (34%).

Pubescence. Metasoma: ST 8: long white-yellowish hairs at the end in contrast to A. g. gomerensis with long yellowish hairs.

Structure. Head: vertex above the ocelli narrow as wide as the ocellar diameter in contrast to A. g. gomerensis as wide as the ocellar diameter (80%) or half of the diameter (20%); labrum process trapezoidal, emarginated, ends left and right side slightly thickened in contrast to A. g. gomerensis slightly thickened (80%) or thickened (20%).

D i s t r i b u t i o n: The distribution of this subspecies is restricted to La Palma ( Fig. 1c ). This subspecies covers mainly altitudes from 400 up to 900 m a.s.l., in one case ( HOHMANN et al. 1993) to 2100 m.

F l i g h t p e r i o d: fromFebruarytoMay.

E t y m o l o g y: The specific name of the subspecies derives from the name of the island La Palma.
