Figs 1 A–C, 9B, E, H
Neoxorides striatus sp. nov. (Fig. 1A) is similar to N. collaris and N. montanus regarding colour and shape, and is intermediate between those species. The face of the male is usually narrower (Fig. 9H) in comparison with the other two species (Fig. 9G). Furthermore, the frons is weakly transversely striate in N. striatus sp. nov. (Fig. 1B) but more evenly shagreened in N. collaris and N. montanus, and the mesopleural furrow usually has more distinct transverse carinae (Fig. 1C, frequently almost as in Fig. 6F). Neoxorides striatus sp. nov. is also distinguished from N. montanus by the usually slightly shorter first tergite in the female (Fig. 9E) (overlap exists), the orange mid coxae in the female, the narrower white line on the sides of the pronotum and the smaller white spots along the inner orbits above the antennal scrobes. The latter character is more evident in females, but the marks are usually shorter and narrower in males with the inner margins concave, while the inner margins are usually convex in the male of N. montanus. From N. collaris it is also distinguished by the longer first tergite (Fig. 9E) and the usually shorter/wider white spots along the inner orbits (Fig. 9B).
The weak striation of the frons in combination with the striate sides of pronotum and transverse carination of the mesopleural furrow is diagnostic.

EUROPE • 1 ♀; “ 1881-93 ”; coll. Buchecker; probably of Central European origin; NHMUK.
Fore wing length 6–14 mm. Antenna in both sexes with 28–36 flagellomeres. First to fourth flagellomere about 4.5–5.0 times as long as wide. Central flagellomeres stout, about 1.5–1.7 times as long as wide. Subapical flagellomeres approximately 0.8–1.0 times as long as wide. Temple slightly widened behind eyes in dorsal view, with coarse scale-like structure following outer and upper margin of compound eye. Frons between antennal scrobes and central ocellus with weak transverse striation (Fig. 1B). Face shagreened, frequently with weak transverse striation in lower half. Head dorsally, behind compound eyes, with rather indistinct punctures on a shagreened background. Inner orbits strongly converging. Face in male narrower than in N. collaris and N. montanus (Figs 1B, 9H). Face below antennal sockets quite smooth with indication of transverse striae in lower part. Mandible chisel-shaped, with sides converging as in N. collaris. Malar space short, about 0.1 times as wide as mandibular base. Wing membrane clear. Pronotum centrally unmodified, not raised as in N. nitens. Sides of pronotum centrally with distinct striae, which extends upwards/backwards to upper part (as in Fig. 6G). Striae often more distinct and larger than in N. montanus. Mesosternum and mesopleuron shagreened with quite dense but clearly discernible punctures, slightly denser and more distinct than in N. collaris and N. montanus. Mesopleuron in front of speculum with weak striae (Fig. 1C). Mesopleural furrow with distinct transverse carinae (Fig. 1C). Mesoscutum shagreened with indistinct punctures, centrally transversely strigose. Notauli deeply impressed, dividing the mesoscutum into three lobes. Scutellum with indistinct punctures on a shagreened background. Propodeum basally weakly aciculate (as in Fig. 6A). Submetapleural carinae complete. First tergite in female 2.0–2.3 times as long as wide (Fig. 9E), in male more variable, about 2.5–3.5 times as long as wide. Sclerotised section of first sternite with a raised keel-like projection centrally often with weak transverse ridges. First to third tergite with transverse rugulose striation that sometimes extends to sides. Male parameres usually more strongly sclerotized, as in typical N. collaris.
Body black. Inner orbit in female with a white line which is about two times as long as wide above the antennal scrobes. Face in male entirely white. Spot below the occipital carina centrally white. The white line on the sides of pronotum is very narrow in both sexes and usually at most about ¼ as wide as the width of the fore femur, missing in small specimens. Tegulae and palpi white. Antennae black or brown. Wing veins and pterostigma testaceous. Coxae in female orange. Mid coxae in large males with large yellow spot that covers most of the outer side or a smaller yellow spot, in smaller males coxae entirely orange. Trochanter and trochantelli yellowish. Legs orange, hind tibia and hind- and mid-tarsi infuscate. Fore and mid femur and tibia sometimes yellow anteriorly.
No host is known for Neoxorides striatus sp. nov. Most records seem to stem from pristine coniferous forests. The available records indicate that the period of flight is June and July in northern Europe.
Only a few recent records. All present localities consist of relatively large fragments of primeval forests. Numerous old specimens from the 19 th century in collections from Sweden and Finland indicates a strong decline in numbers during the last century. Ha, Hs, Sm, Up, Ån, Ög.
The barcodes of this species are separated from their closest barcode (in N. montanus) by 4.6% p-distance. The sequences are stored on BOLD under accession numbers: FBICA170-11 (BC ZSM HYM 07485), FBICA169-11 (BC ZSM HYM 07484).
