PSEUDOANTHIDIUM CANARIENSE ( MAVROMOUSTAKIS, 1954)

( FIGS 2C , 23C , 25A, C, E )

Anthidium canariense Mavromoustakis, 1954: 712– 715 , ♀ ♂. Type locality:‘Canary Islands’ (without specific locality) [holotype ♀, allotype ♂, paratype ♀ (NMW); paratypes 2♀ (listed in publication as deposited in the Mavromoustakis personal collection), likely deposited at the MCN].

Material examined: Four females, seven males (see Supporting Information, Table S1 for specimen data).

Distribution: Spain (Canary Islands): Santa Cruz de Tenerife, Gran Canaria, La Gomera ( Fig. 22C ).

Host-plant associations: Asteraceae Gran Canaria Argyranthemum cf. frutescens (L.) Sch. Bip. (male visits), Asteriscus graveolens subsp. stenophyllus (Link) Greuter (male and female visits), Carduus tenuiflorus Curtis (female visits); Tenerife and Grand Canaria Carduus sp. (female visits); Tenerife, Grand Canaria, La Gomera Galactites tomentosa Moench (male and female visits); Tenerife Scolymus hispanicus L. (male and female visits); Brassicaceae Gran Canaria Erysimum scoparium (Brouss. ex Willd.) Wettst. (male visits), Hirschfeldia incana (L.) Lagr.-Foss. (female visits); Lamiaceae Tenerife Cedronella canariensis (L.) Webb & Berthel. (male visits) ( Hohmann et al., 1993).

Diagnosis female: The female of P. canariense may be distinguished from other members of this complex by the following combination of characters: punctation on terga comparatively coarse, as large or larger than punctation on mesonotum, with shiny interspaces between punctures; largest punctures on black part of scutellum approximately equal in diameter to those of largest punctures on T2; maculations on head, mesosoma and metasoma dark orange; shiny spaces between punctures on T3 narrow, less than one-quarter of a puncture wide; hairs on inside of third basitarsus dark brown and with individual hairs mostly thicker than hairs on outside surface. Colour of maculations orange-yellow ( Fig. 25A ).

Diagnosis male: The male of P. canariense may be distinguished from other members of this complex by the following combination of characters: gonostylus approximately parallel-sided and unnotched at apex ( Fig. 23C ); lateral comb on S5 small, with longest teeth shorter than maximal width of hind basitarsus; posterior, premarginal brush on S3 with hairs hooked at tips; shiny, hairless zone on S3 between posterior premarginal brush of hairs and anterior zone of dense, velvety pilosity very short, about one-third of the width of the sternum, dark, chevron-shaped, without medial extension extending anteriorly along the midline of sternum; posterior margin of S2 medially emarginate, S2 otherwise covered in silvery pilosity except for a more or less hairless posterior margin. Colour of maculations orange-yellow ( Fig. 25C ). Posterior margin of T7 with deep, nearly semi-circular emargination medially ( Fig. 25E ).

Figure 2. Best-scoring maximum likelihood tree based on analysis of COI data. Numbers shown at nodes are maximum likelihood bootstrap values based on 1000 bootstrap replicates in RAxML. Only bootstrap values greater than 50% are shown. Terminals are labelled with a DNA extraction code, species name, collection locality and either as male (m) or female (f). Barcodes were obtained using Sanger sequencing technology, except for those corresponding to specimens 1802 and 1805, which were obtained from non-UCE assemblies generated during UCE sequencing.
