Ophion ellenae Johansson

sp. nov.

Ophion ellenae Johansson   sp. nov.


Figs 8D View Fig , 10G View Fig , 18F View Fig , 21A, C View Fig , 32 View Fig


Superficially similar to Ophion inclinans Johansson   sp. nov. and O. arenarius Johansson   sp. nov., but never with the dorsal undulation on the first tergite. Usually more densely punctured face below the antennal sockets, more prominent and sharper pleurosternal angles and stouter flagellomeres. Closely related and very similar to O. perkinsi   and O. norei Johansson   sp. nov., but with the head more narrowed behind the eyes, no gap between the eye and lateral ocellus, complete anterior transverse carina of the propodeum and more numerous flagellomeres. Most closely related, however, to O. matti Johansson   sp. nov., but distinguished by the more shining and less densely punctate mesoscutum, the shorter area superomedia and the more elongate basal flagellomeres.


The species is named in honour of the authors’ wife, Ellen Nystedt.

Fore wing length 15–16 mm. Antenna with 52–54 flagellomeres. First flagellomere 3.5 times as long as wide. Second flagellomere about 2.2 times as long as wide. Central flagellomeres stout, about 1.2–1.3 times as long as wide. Subapical flagellomeres approximately 1.5 times as long as wide ( Fig. 8D View Fig ). Temple relatively short. Head in lateral view with temple 0.4–0.5 times as long as compound eye ( Fig. 21C View Fig ). Gap between compound eye and lateral ocellus 0.1 times the diameter of ocellus. Face below antennal sockets with dense punctures. Interstices between punctures 0.5 times their diameter. Malar space about 0.1–0.2 times as long as mandibular base in female and male. Mandibular gape rightangled, with internal angles. Wing membrane clear. Ramellus short, reaching 0.2–0.4 times the width of the discosubmarginal cell. Radius sinuous. Mesoscutum shining with irregular and weak punctures, interstices between punctures about equal to their diameter ( Fig. 21A View Fig ). Mesopleuron shagreened with deep, dense punctures, space between punctures 0.5 times their diameter. Epicnemial carina, in antero- ventral view, with pleurosternal angles almost in level with sternal angles, pleurosternal angles right angled. Scutellum quite wide with distinct lateral carinae in basal 0.8–0.9 (as in Fig. 6C View Fig ). Propodeum with very weak rugose structure, shining with anterior and posterior transverse carina often strongly raised. Central longitudinal carinae strong, lateral longitudinal carina absent. Area superomedia relatively short, almost square ( Figs 10G View Fig , 18F View Fig ). Hind trochantellus shorter than wide in dorsal view. Legs normal with hind femur about 6.0 times as long as wide. Sclerotised part of first sternite ending distinctly posterior to spiracle at a distance equal to that between hind margin of the sclerotised part of the first sternite and hind margin of the first tergite. Inner spur of hind tibia as long as 0.5 times metatarsus.


Body testaceous. Mandibular teeth black. Head with inner and outer orbits yellow. Ovipositor sheath testaceous.

DNA barcode

The DNA barcode sequences of six Swedish specimens of Ophion ellenae Johansson   sp. nov. are available at the BOLD systems database (www.boldsystems.org, BIN. BOLD: ADM4635. Specimen codes: STI-NJBC: 87, 188, 301, 305–307).


One male and one female kept in NHRS ( Sweden, Upl, Sandhamn, Ljungdahl leg.) have been reared from the rare moth Hadena bicruris (Hufnagel, 1766)   . The available data for the parasitoid suggests a connection to open dry, sandy or rocky grassland, which also is the main habitat of the known host and some of its close relatives. Ophion ellenae Johansson   sp. nov. is active from late July to early September.

Distribution in Sweden

Most frequently collected in coastal areas of the eastern parts of Central Sweden where it can be locally abundant. Older records are known from a wider area in Central Sweden (Uppland, Västmanland and Dalsland) indicating a decline during the last century.


This species is very closely related to O. matti Johansson   sp. nov. ( Fig. 4 View Fig ). The two species are very similar and also share the same BIN. The slight but distinct morphological differences, supported by the barcoding results motivates the description of a separate species.
