[Michener 2007]
Mandible with two teeth or apex bilobate.
Vertex normal, in frontal view not surpassing upper ocular margins by ocular width.
Head in frontal view rounded or trapezoidal, never rectangular.
Inner margins of eyes markedly convergent below.
Genal area narrow.
Omaulus (=prepectus) rounded or merely angular.
Malar area shorter than basal flagellar diameter.
Head shorter, circular or trapezoidal in frontal view;
pronotum short, dorsolateral angle rounded or pointed.
Facial fovea elongate, somewhat surpassing upper ocular margin, converging strongly toward ocelli, terminating closer to ocelli than to compound eye.

H. (Parapros.) taeniolatus

[Dathe, Scheuchl & Ockermüller, 2016]: to rule out pictipes
4.5-5.5 mm.
Facial lateral spots mostly large, filling.
Malae narrow.
Thorax finely chagrined.
Mesopleures scattered, very shallowly punctate and finely striate.
Propodeum truncate sharp-edged around.
Central area sharply slow-striate, middle with pit.
Tergum 1 very finely shagreened and shallowly and finely to deeply punctate, dots dense or scattered (dot spacing 1-3 Ø); following terga more distinctly shagreened.
Lateral fringes present.
Hylaeus taeniolatus

On a colour pantrap. 11.6 mm.
HEAD: Antennal flagellum pale brown below. Second flagellum segment a bit longer than 3rd and 4th together, that is: A3>(A4+A5) or A3/(A4+A5)=1.27. Face transverse, wider than long. Fovea short, slightly narrowed below, ending at the level of the middle of the antennal insertion; foveae wide, top end about one ocellar width from the outer ocelli, foveal index (above): 0.5. Clypeus flat, transversely wrinkled. Labrum lamella notched. Mandibles short. Thick bristles on paramandibular process present. Face hairs pale yellow.
MESOSOMA: Hairs on mesonotum, scutellum and postscutellum short, but not scale-like nor spindle-shaped. Mesoscutum punctuation dense, tegument dull (reminiscent of that, i.e., A.flavipes). Central area clearly wrinkled, structured in the sculpture as roughly as the side parts of the central area.
LEGS: Legs tegument black, except the brown last segments of tarsi. Inner side of hind femora shallowly depressed, with a row of hairs. Tibial scopa pale yellow. Inner spur of hind tibiae slightly broadened at base, curved backwards.
METASOMA: Tergites T1-T3 densely punctured, more densely in the depressed apical part. Tegument smooth, shiny, lightened apically, yellowish. Tergite ends from the 2nd and the following with narrow yellowish hair bands, complete or narrowly interrupted. Terminal hair fringe orange. Pygidium rounded at tip.
REMARKS: Fovea coloured in green in one picture to emphatize its shortness. The pictures of the underside of head, as well as those of the wings, are from another specimen of the same form from a nearby locality.
Somehow similar to A.polita, or A. relata, but not sure about the species.

Caught in a colour pantrap.
Female.
Body length: 9.5 mm.

Determination following Blüthgen 1924 and Niu et al 2007.

Face ratio length/width= 2,49 mm/2,53mm=0,99
Mesosoma width (outer rims of tegulae)=1.84 mm.
Mesosoma width/face width=71/70=1.01.
Central area/horizontal area of propodeum=about 0.75.

Main differences with H.vestitus:
Size
Face more rounded (l/w=0.97-0.99 vs 0.91-0.93)
Labral appendix bifid (here not visible) and not simple.
Hairless propodeal dorsal enclosure nearly as long as propodeum mesally, almost reaching the posterior margin of the dorsal area of propodeum.
Inner hind tibial spur pectinate, with 7-8 teeth.

Also:
Antenna dark underside (or at least less testaceous than vestitus).
Head, viewed from the front, raised above the eyes, rounded, but somewhat trapezoidal.
