Ophion paraparvulus Johansson  sp. nov. is one of the species in an aggregate previously treated under the name Ophion parvulus  . Ophion paraparvulus Johansson  sp. nov. is morphologically intermediate between Ophion parvulus  and Ophion tenuicornis Johansson  sp. nov. and has the flagellomeres stouter and less pilose than O. tenuicornis Johansson  sp. nov., but longer and more pilose than O. parvulus  . It is also easily confused with O. kallanderi Johansson  sp. nov., but distinguished by the shorter temples and the stouter central flagellomeres. The posterior transverse carina is, as in O. kallanderi  , usually widely interrupted in the middle with only the lateral parts distinct ( Table 1).


The species is very similar and closely related to Ophion parvulus  .

Fore wing length 16 mm. Antenna with 53–54 flagellomeres. First flagellomere 4.0 times as long as wide.Second–fourth flagellomere about 2.5–3.0 times as long as wide. Central flagellomeres elongate, about 2.0 times as long as wide. Apical flagellomeres 1.8–1.9 times as long as wide. Flagellomeres with quite long prominent pilosity. Length of pilosity in females at least 0.5 width of flagellomere ( Fig. 8BView Fig). Head narrow behind eyes, in lateral view with temple 0.3 times as long as compound eye. Ocelli in female large, in dorsal view covering the inner margin of compound eye. The distance between lateral ocelli in female about 0.3 times the diameter of the ocellus. Malar space about 0.1 times as long as mandibular base. Mandibular gape right-angled, with internal angles. Wing membrane clear. Ramellus distinct, reaching 0.2–0.4 the width of discosubmarginal cell but sometimes small or absent. Radius evenly curved. Mesopleuron weakly shagreened with deep 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, slightly obtuse. Scutellum with lateral carinae only indicated basally. Propodeum with very weak rugose structure, shining with anterior transverse carina strongly raised. Posterior transverse carina usually widely interrupted centrally. Longitudinal carinae delimiting area superomedia and lateral longitudinal carinae often weak or absent, but normally clearly indicated at the junction with the posterior transverse carina. Hind trochantellus shorter than wide in dorsal view. Legs normal with hind femur about 6.0–7.0 times as long as wide. Sclerotised part of first sternite ending level or slightly posterior to spiracle. Inner spur of hind tibia as long as 0.4 times first hind metatarsus. Male unknown.


Body light testaceous, frequently with diffuse pale markings as in O. parvulus  . Mandibular teeth black. Ovipositor sheath usually concolourous with posterior metasomal segments.

DNA barcode

The DNA barcode sequences of two Swedish specimens of Ophion paraparvulus Johansson  sp. nov. are available at the BOLD systems database (www.boldsystems.org, BIN. BOLD: ADG1399. Specimen codes: STI-NJBC: 36, 40).


Very little is known about the biology of this species. It has been collected in areas with mature semiopen mixed forests. The flight period seems to be mid June to mid July. It is active earlier in the season than its sibling species O. tenuicornis Johansson  sp. nov. and O. costatus  .

Distribution in Sweden

Rare and possibly confined to areas with favourable climate in Southern Sweden.
