C538E11AFFAFFFE3FF04F8DDFA723B1D.taxon	diagnosis	The subgeneric classification of the genus Hylaeus has yet to be fully resolved, and some problems persist even within the European fauna, particularly in the classification of some species and the morphological concepts of the subgenera (Le Divelec, unpublished). Clarifying this classification is beyond the scope of this work and we can only suggest following the latest key to the Palearctic subgenera provided in Michener (2007). Although the identification of the males should be unambiguous thanks to the genitalia, there is a high risk of confusion in the females, more particularly between those of the garrulus group (subgenus Prosopis) and those of the nivalis group (subgenus Hylaeus). The latter group, as described in Dathe (2000), is artificial and it is necessary for it to be redefined in a separate work (Le Divelec, unpublished). Females of both groups share important diagnostic characteristics: a rounded propodeum without transverse or oblique carina, a T 1 with apical fringes, light hairs on the last metasomal segment. As a result, some of the specimens of the garrulus group examined were previously confused with members of the nivalis group. The garrulus group can be distinguished from the nivalis group by the largely reticulate and strigate basal triangle (basal triangle with weak longitudinal ridges basally in the nivalis group, most of its surface only with tesselate tegument), the comparatively narrower scapus, i. e. as large as pedicel and narrower than median flagellomeres (larger than pedicel and as large as median flagellomeres in the nivalis group), the comparatively denser and deeper punctation on mesepisternum, and the distinct punctation on the hypoepimeral area (this area is tesselate without or with a few indistinct punctures in the nivalis group). The Iberian garrulus species group can be recognized from other Prosopis by a distinctive combination of characters, somewhat intermediate between the gibbus and the variegatus species groups. Another species of Prosopis, H. gazagnairei (Vachal, 1891) also exhibits such an intermediate morphology, with an external morphology very similar to the species of the garrulus species group, more particularly in the males (see table 2). Due to those numerous similarities, members of the garrulus species group have been regularly misidentified as H. gazagnairei. As a matter of fact, the only published European record of H. gazagnairei, from Cartagena in Spain (Ornosa & Ortiz-Sánchez 2004), is based on a specimen housed at MNCN. The specimen was studied for this work, and it turned out to be H. teruelus. Therefore, it seems noteworthy to detail the main differences between H. gazagnairei and the members of the H. garrulus group, additionally to the differences with the two other main groups, the gibbus and the variegatus groups (Tables 1 – 2). The females of the garrulus species group are very similar to those of the gibbus group. They can be immediately recognised by the minute and indistinct punctation on the mesosternum which is conspicuously finer than that of mesepisternum, merged within the densely tesselate sculpture of the tegument. In the West Mediterranean area, other Prosopis species have a distinct punctation with small to large punctures on the mesosternum. The facial structure in the males of the garrulus group is reminiscent of the variegatus group (Fig. 3 G), with a trapezoidal and moderately dilated scape (0.8 × as wide as long) and a crescent-shaped depression extending between the eyes, over the apex of the supraclypeal area and the base of the clypeus (Figs 6 A, 6 F, 6 K). As said previously, their general body is also very similar to that of H. gazagnairei. Males of the garrulus group can be recognized by the unique morphological features of their genital capsule, and more particularly by the structure of their penis valve. The inner surface of the penis valve is uniformly flat, its dorsal surface homogeneously oblique across all its length in cross section (Figs 6 D, 6 I, 6 N); in other groups, the dorsal surface is flattened and features a distinct inner angle due to the upper sclerotized part being swollen either along its entire length (Figs 4 C, 4 M) or at least basally, as seen in the gibbus group (Fig. 4 H). The outer surface of the penis valve features a sharply elevated, straight longitudinal carina extending from the basal apodeme (valvura) to the apex of the penis valve (Figs 6 E, 6 J, 6 O). Above this carina, the cuticle is deeply concave, whereas in other groups, it is nearly flat. Below the carina, the cuticle is swollen, forming a deep and large invaginated opening just above the ventral subapical lobe. In contrast, other groups either lack this carina or have it reduced to a basal ridge, with the cuticle below it remaining flat and displaying only a shallow invagination above the ventral subapical lobe (see Figs 4 E, 4 J, 4 O). In the garrulus group, the ventral subapical lobe is produced apically, far beyond the level of the ventral sinus, in a long and narrow free membranous lobe separated by a long sulcus from the ventral margin of the penis valve (Figs 6 E, 6 J, 6 O). In other groups, the subapical lobe is sclerotized, without membranous lobe, and entirely fused with the ventral margin of the penis valve (Figs 4 E, 4 J, 4 O). Additionally, to this unique penis valve, it is worth mentioning that the gonoforceps in the garrulus group are conspicuously arcuate or angulate apically and with a basal depression (Fig. 6 D, 6 I, 6 N); the volsella has a short digitus, flat in lateral view (Fig. 8 H). In other groups, the gonoforceps are straight to slightly curved inwards with a basal depression (Figs 4 C, 4 H, 4 M); and the volsella has a long digitus (Figs 4 D, 4 I, 4 N), large in lateral view. To give more context to the information in tables 1 and 2, a simplified key to identify the main species groups and all the other species of the Prosopis subgenus that are not associated to them is here provided for Europe and Maghreb.	en	Divelec, Romain Le, Michez, Denis (2025): Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae).

C538E11AFFA5FFE2FF04F89BFC693C41.taxon	diagnosis	The three species of the garrulus species group can be separated by the combinations of characters provided in Tables 3 and 4. Dathe (2000) proposed as diagnostic characters in females the sculpture of the propodeum, the length of the face, the facial fovea, and, in males, the shape of the S 8 and gonoforceps. Despite examining a larger material in this study, no differences were found in the sculpture of the propodeum nor in the shape of the S 8. In fact, none of the H. teruelus specimens we examined exhibited a median process as large as the one depicted in the figure 29 of Dathe (2000). It should be noted that the drawings of the terminalia of H. garrulus and H. teruelus in Dathe (2000) were switched – Figures 28 - 29 corresponding to H. teruelus and not H. garrulus. All species of the group may exhibit a S 8 tip that ranges from pointed to slightly dilated. The length of the clypeus and malar area, although not clearly described in Dathe (2000), appears to differ between the three species. However, these traits are difficult to use for identification without precise measurements, particularly since H. woodi exhibits intermediate proportions. The most distinctive and useful character to identify the species are the facial foveae in females, and in males, the mesosternal structures, the elevation of S 3, and the genital capsule.	en	Divelec, Romain Le, Michez, Denis (2025): Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae).

The examined material (Fig. 9) and the published records suggest that it is scattered but widespread in southern and central Spain, but biased towards the eastern half of the country. The single specimen reported from Portugal (Baldock et al. 2018) should be re-examined to confirm the presence of this species in the country. At the time, the species concepts were unclear, and all the Portuguese specimens examined by us and I. Cross (pers. comm.) belong to H. teruelus. Additionally, the seemingly eastward-restricted distribution of H. garrulus in Spain makes its presence in Portugal unlikely.	en	Divelec, Romain Le, Michez, Denis (2025): Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae).

C538E11AFFA0FFE6FF04FE8AFCA53E14.taxon	distribution	Distribution. Spain and Portugal (Warncke 1981, Dathe 2000, Baldock et al. 2018). The examined material (Fig. 9) and the published records suggest that it is scattered but widespread in all Spain and Portugal. It occurs in a wide variety of habitat, from the coast to high mountains (2000 – 2100 m). Only one published record is known so far from Portugal (Baldock et al. 2018). The male of H. convergens from Baixo Alentejo reported in (Baldock et al. 2018) was also confirmed to belong to H. teruelus (I. Cross, pers. comm.).	en	Divelec, Romain Le, Michez, Denis (2025): Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae).

C538E11AFFA0FFE6FF04FE8AFCA53E14.taxon	discussion	Remark. Dathe (2000) differentiated the male of H. convergens from H. teruelus based on its supposedly smoother propodeal sculpture and a narrower median process on S 8. As mentioned earlier, these subtle differences fall within the variability range of H. teruelus. Upon the examination of the male holotype of H. teruelus, no substantial morphological differences were identified between males of H. teruelus and H. convergens. Morphology and barcoding of the female associated to H. teruelus also suggest that sexes have been incorrectly paired (Fig. 1). As a result, H. convergens is a junior synonym of H. teruelus.	en	Divelec, Romain Le, Michez, Denis (2025): Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae).

C538E11AFFA0FFFAFF04FD84FEB23A11.taxon	distribution	Distribution. The examined material (Fig. 9) suggests a distribution range like H. garrulus, most of the locations situated in the southernmost regions of Spain and a few in central Spain. However, its distribution seems to be more strongly associated to calcareous soils. More occurrence data are needed to confirm this tendency. It inhabits a wide variety of habitat, occurring from the plains to the high mountains (2000 – 2100 m).	en	Divelec, Romain Le, Michez, Denis (2025): Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae).

C538E11AFFBFFFF9FF04FE8AFB103FAD.taxon	description	Hylaeus gazagnairei is mentioned for the first time in the European context by Dathe (1980) who specified that the presence of this species in Europe was unclear but expected in its Mediterranean parts. It is definitively reported from Europe in southern Spain by Ortiz-Sánchez et al. (2002) without more detail. The species has been subsequently included in the keys to Iberian Hylaeus (Ornosa & Ortiz-Sánchez 2004, Ortiz-Sánchez et al. 2003) following Dathe (1980). However, none of the keys previously mentioned provide an unambiguous species concept for H. gazagnairei. For the female, the main characters provided concern the colour, i. e. black face and red legs, when the colour is highly variable with many females having light marks on the face. As for the male, its morphological similarity with the males of the garrulus species group made its identification difficult at a time when no clear diagnosis of the garrulus group was available. For these reasons, its presence in Europe remained doubtful despite the Spanish record. The original record has only been detailed by Ornosa & Ortiz-Sánchez (2004) and, after examination, the associated specimen turned out to be a specimen of H. teruelus. After examining a substantial material of Hylaeus from the Mediterranean, and more particularly from Spain and Sicily, no true H. gazagnairei were found. Consequently, we consider that this species does not occur in Europe. According to the material we examined (178 ♀ 70 ♂, including type material; Algeria, Libya, Morocco, Tunisia; see supplementary material), Hylaeus gazagnairei seems to be restricted to the Maghreb where it is a common species ranging from Morocco to Libya.	en	Divelec, Romain Le, Michez, Denis (2025): Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae).
