Divelec, Romain Le & Michez, Denis, 2025, Taxonomic revision of the garrulus species group in the bee genus Hylaeus Fabricius, 1793 (Hymenoptera: Apoidea, Colletidae), Zootaxa 5642 (2), pp. 127-146 : 140

Hylaeus teruelus ( Warncke, 1981)

Figures 5E–H , 6F–J .

Prosopis garrula ssp. teruela Warncke, 1981: p. 162 ,

♂ (not ♀). Type locality: Spain, Teruel , Bronchales (Holotype ♂, OÖLM, examined).

Hylaeus convergens Dathe, 2000: p. 168 ,

♀ ♂. Type locality: Spain, Asturias, Picos de Europa (Holotype ♀, SDEI, examined) .

New synonym.

Examined material. 10♀ 15♂, Spain and Portugal (see supplementary material) .

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.).

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 S8. 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 .
