Diagnosis
The species is most similar to Ophion kevoensis but has the face and head in anterior view narrower. Also similar to Ophion sylvestris Johansson sp. nov. but larger and with ovipositor sheath testaeous (black or dark brown in O. sylvestris Johansson sp. nov.). The barcoded specimens form two groups, but no morphological evidence supports the presence of two separate species at this point.
Etymology
This species is named in honour of the British hymenopterist Gavin Broad.
Material examined
8 ♀♀ (Sweden).

Description
Fore wing length 15–17 mm. Antenna with 52–55 flagellomeres. First flagellomere about 3.5–4.0 times as long as wide. Central flagellomeres about 1.5–1.6 times as long as wide. Subapical flagellomeres approximately 1.5 times as long as wide. Temple in lateral view 0.4–0.5 times as long as compound eye. Head in dorsal view with gap between compound eye and lateral ocellus about 0.1–0.3 times the diameter of the ocellus. Malar space slightly longer than in O. slaviceki, in female about 0.3 times as long as mandibular base. Face below antennal sockets narrow (Fig. 16F) with quite scarce and shallow punctures. Gap between mandibles obtuse or right angled, with internal angles present. Wing membrane transparent. Ramellus long, 0.3 times the width of the discosubmarginal cell. Radius sinuous. Structure of mesopleuron weakly shagreened with distinct punctures. Interstices between punctures about equal to their diameter. Epicnemial carina, in antero-ventral view, with pleurosternal angles obviously anterior to sternal angles. Pleurosternal angles rounded, obtuse to right angled (as in Fig. 9E). Scutellum with lateral carinae present in basal 0.2. Anterior transverse carina of propodeum present. Posterior transverse carina only present laterally, widely interrupted centrally. Petiolar carina and longitudinal carina delimiting area superomedia weak. Sclerotised part of first sternite ending level to spiracle. Hind trochantellus shorter than wide in dorsal view. Legs normal, with hind femur about 6.0–6.5 times as long as wide. Hind trochantellus shorter than wide in dorsal view. Inner spur of hind tibia about 0.3–0.4 times as long as hind metatarsus. Male unknown.
Colour
Body dark testaceous. Outer eye margins yellow. Inner eye margins usually only yellow above antennal sockets. Mandibular teeth black. Ovipositor sheath testaceous, concolourous with posterior metasomal segments.
DNA barcode
The DNA barcode sequences of four Swedish specimens of Ophion broadi Johansson sp. nov. are available at the BOLD systems database (www.boldsystems.org. Specimen codes: STI-NJBC: 210–211, 214, 263).
Ecology
The species occurs in open pine forests on sandy or rocky ground. The main period of activity in Sweden seems to be early summer, May–June.
Distribution in Sweden
Probably a quite common species, but partly overlooked.
Remarks
Some males that were collected alongside the females from Västergötland resemble the males of Ophion kevoensis but have the malar space shorter. The specimens could represent the males of this species but the connection to the females is too vague to found a formal description on.
