Andrena (Micrandrena) catula WARNCKE, 1968

Syn. Andrena wollastoni catula WARNCKE, 1968

H o l o t y p e: 1♀ Gran Canaria, Lagunova, 20.03.1928, collector unknown (ID-No OLML26, former holotype of A. w. catula).

P a r a t y p e s (fomer paratypes of A. w. catula with the exception of OLML32 ): 1♀ Gran Canaria , Azuaje, 200 m, 05.05.1934, collector unknown (ID-No OLML27 ) ; 1♀ Gran Canaria , Lagunova, 20(?).03.28, collector unknown (ID-No OLML28 ) ; 1♀ Gran Canaria , Santa Brígida, 500 m, 15.04.1976, leg. Wolf (ID-No OLML32 ) ; 1♂ Gran Canaria , Valle de Tejeda, 1050 m, 28.- 29.03.1949, leg. Lindberg (ID-No OLML31 ) ; 1♂ Gran Canaria , Gando, 20 m, 23.02.1935, collector unknown (ID-No OLML36 ) .

S t a t u s: WARNCKE (1968) described A. w. catula as endemic to Gran Canaria based on nine specimens (holotype: 1♀; paratypes: 5♀♀, 3♂♂). This is in accordance with the information of BLANK & KRAUS (1994). In the OLML, the holotype and four paratypes (2♀♀, 2♂♂) are deposited. The deposition of four paratypes (3♀♀, 1♂) is unknown. The specimens concerned are as follows: 1♀ La Aldea de San Nicolás, 01.03.1949, leg. Lindberg ; 1♀ Arucas , 02.03.1949, leg. Lindberg ; 1♀ San Bartholomé de Tirajana , 14.03.1950, leg. Lindberg ; 1♂ Cruz de Tejeda , 1450 m, 06.-08., 11.- 13.03.1950, leg. Lindberg.

A further 17 specimens of A. catula were detected in the Warncke collection (OLML). In 1970, 1973, and 1976, WOLF (1980) collected A. catula on Gran Canaria (12♀♀, 3♂♂, Maspalomas, 975 m a.s.l., field fringe and Monte-Alto vegetation, 02.04.1970, 13.04.1973). These specimens are all provided with a determination label from Warncke (A. w. catula).

The holotype and paratypes of A. w. catula were examined in the OLML. The holotype (1♀) and four paratypes (2♀♀, 2♂♂) ( WARNCKE 1968) are designated as A. catula supplemented by a female collected by Wolf (ID-No OLML32).

F o r m e r d e s c r i p t i o n: WARNCKE (1968) characterised A. w. catula as follows (translated from German): ‘Differences compared to the nominal taxon: labrum process broader, triangular and flat-topped; clypeus fine punctured and shagreened; scutellum shining; abdomen slightly shagreened and shining, especially on the first tergite; stigma black.’ This characterisation was adopted by GUSENLEITNER & SCHWARZ (2002).

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. catula is characterised by the following specific features:

F e m a l e: Colour. Head: flagellum black (brown) (72%), black (dark brown) (22%) or black (light brown) (6%) ( Figs. 7c, d ). Mesosoma: femur, tibia, and basitarsus black or dark brown; mediotarsi reddish-brown ( Fig. 7a ); wings light brownish toned, veins yellowish to reddish-brown ( Fig. 7a ); pterostigma yellowish and brown marginated (not black as indicated by WARNCKE 1968). Metasoma: T1-4 black with black to dark reddishbrown depression zone ( Fig. 7g ); T5 with depression zone reddish-brown ( Fig. 8e ).

Pubescence. Head: clypeus and supraclypeal area with white-yellowish hairs ( Figs. 7c , 8a ); paraocular area without (71%) or with some brownish hairs (29%) between subantennal socket and the facial fovea; scapus and antennal socket with dorsal longer and ventral shorter white-yellowish hairs; genal area with white hairs ( Fig. 7c ); facial fovea in the upper part with brownish hairs ( Fig. 7d ), in the lower part with white-yellowish hairs; vertex behind the ocelli with some longer white-yellowish hairs ( Fig. 7c, d ). Mesosoma: mesoscutum and scutellum with-yellowish hairs, laterally with longer hairs; mesepisternum with white-yellowish hairs; propodeal corbicula with yellowish-white hairs ( Fig. 7e ), and some hairs in the centre; trochanteral and femoral flocculus with yellowish -white hairs; tibial scopa dorsally with yellowish-white hairs, dorsobasally with reddishbrown hairs, ventral with yellowish-white hairs ( Fig. 8d ). Metasoma: tergites scarcely hairy; T2 and T3 (T4) with lateral white-yellowish, fragmentary open hair bands (dense row 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 white-yellowish hairs, in the centre reddish-brownish hairs, reaching to the pygidium; T6 with (reddish) brown hairs ( Fig. 8e ).

Structure. Head: clypeus convex without impunctate line, clearly shagreened, slightly dull, shallow more or less densely punctured (PD: 28 μm, PDI: 14-70 [84] μm) ( Fig. 8a ); labrum process liguliform (74%), or liguliform-trapezoidal (26%), slightly rounded on the top, partly thickened, laterally on the the top more or less parallel.
