T1 with pair of latero-apical fringes of hairs ( Fig. 8E ). T3–6 with uniform close to sparse minute punctures, lightly shagreened. Metasomal sterna flat or, more often, with medial transverse bur on S3 and S4 ( Fig. 6M ). Metasomal segments covered with very short suberect light hairs. S7 with short light hairs on distal lobe and on proximal lobe apex, proximal lobe long and narrow, 2× as long as distal lobe ( Fig. 8F ). S8 medially produced into long and narrow tip ( Fig. 8G ). Gonoforceps depressed basally, tapering and conspicuously angulate apically ( Fig. 6N ). Aedeagus outline circular. Inner surface of penis valve uniformly flat, oblique ( Fig. 6N ). Outer surface of penis valve with sharp medial longitudinal carina, defining flat, perpendicular area; tegument below medial carina swollen into a large protuberance, opening posteriorly into a deep, invaginated fovea ( Fig. 6O ). Ventral margin with extended membranous subapical lobe, projecting well beyond ventral sinus ( Fig. 6O ).

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).

Etymology. Named after our colleague Thomas James Wood (Leiden, Naturalis Biodiversity Center), in recognition of his significant contributions to the study of the Iberian bee fauna and his substantial support in the study of Hylaeus .
