Distribution of Eurybregma (FLOW 14 Jan 2019)

Recognized species

(distribution information may be incomplete)

Note: Emeljanov, 1982 divides this genus into the subgenera Bregmodes Emeljanov, 1982 (type Eurybregma pseudagropyri Emeljanov, 1966, apparently monotypic); Priapyx Emeljanov, 1982 (type Eurybregma pygalis Emeljanov, 1973, 2 species), and Eurybregma.  Hamilton (2002) moved most of the North American species formerly in Eurysa into Eurybregma.  Emeljanov 2019 moved Nearctic Eurybregma into Euryburnia.

New World

Now in Euryburnia Emeljanov 2019.

Plant Associations

Grasses, as follows

Eurybregma nigrolineata is reported off the grasses Elymus repens (L.) Gould, Holcus lanatus L., and Dactylis glomerata L. (and ‘quackgrass meadows’).
Eurybregma eurytion, Eurybregma magnifrons – Agropyron sp. (Poales, Poaceae).
Eurybregma pseudagropyri is reported from the grasses Agropyron pseudoagropyrum and Leymus chinensis.

From Anufriev and Emeljanov 1988, Wilson et al. 1994; Nickel 2003; See FLOW for possible additional plant associations.

Paarasites (both from Eurybregma nigrolineata)

Charletonia cardinalis (c. l. koch, 1837) (C. L. Koch, 1837) (Acari, Trombidiformes, Erythraeidae) according to Stroinski et al. 2013: 197. (Ectoparasite)
Elenchus tenuicornis (Kirby, 1815) (Insecta, Strepsiptera, Elenchidae)

Economic Importance

Probably limited.  New World species are infrequently encountered.

Recognition

Robust species, vertex wider than long, carinae relatively obscure; frons broad, widest near fastigium, carinae obscure near fastigium.

Description of genus from Anufriev and Emeljanov 1988

Macrocoryphe [~vertex] short and wide, noticeably wider than long and wider than transverse diameter of eye. Eumetope [~frons, including parts anterior to transverse carinae of vertex] widening from clypeus to eyes, parallel-sided between eyes, not more than 1.5 times as long as wide. Carinae of eumetope smoothed; usually 2 parallel carinae standing out, sometimes they are weakly noticeable or disappear; a median carina is noticeable between less distinct paired carinae in some cases. Carinae disappear completely on the turn of eumetope into acrometope; the turn is smoothed. Lateral carinae of disc of pronotum diverging backwards, slanting outwards and disappearing, not reaching posterior margin. In brachypters, fore wings rounded truncate at apices, reaching abdominal tergites II-III in females and tergites IV-V in males. Posttibial spur about half as long as basal segment of hind tarsus, bearing usually less than 10 large lateral denticles, blunt and without denticle at apex. Male. Pygofer with not interrupted posterior edging; bridge of pygofer often with wide dorsal projection in the middle. Anal tube with a pair of differently developed teeth ventrally. Styli becoming thinner to apex, diverging. Aedeagus variously developed, more or less elongate, sometimes compressed laterally.

Old World

Key to 3 species from Anufriev and Emeljanov 1988 (figure references to that work, included below)

1. Processes of anal tube long; the body of anal tube about as wide as high. Aedeagus compressed laterally and with great number of denticles; articulatory plate of theca long, divided into two parts. Subgenital plate protruding outwards, large; lateral lobes of simple shape, without steps and excisions. (Subgenus Bregmodes Em.). Light, brown or whitish, with dark brown, mostly longitudinal pattern. Head brown with light carinae; macrocoryphe with whitish spot posteriorly. A paired dark stripe running on disc of pronotum, scutellum and second claval vein (A1 and Pcu + A1); another stripe arising behind eyes bifurcates on fore wings running along veins R and Cu. In male, abdomen with lightened dorsally midline, sides and indistinctly midlines between them; in female, paired intermediate light stripes strongly widened, and dark stripes narrowed accordingly. Venter mostly light. 2.4-3.5. – Transbaikal, Tuva, Altai. – Mongolia. – On Leymus chinensis in meadow steppe habitats. Mid-June to late July. (Figs. 328: 1-9)  …  E. (B.) pseudagropyri
1– Processes of anal tube short or anal tube very high. Aedeagus with 2-3 teeth; its shaft not wide, not compressed laterally; articulatory plate of theca short, simple. Subgenital plate not protruding; lateral lobes with step or smooth excision … 2

2. Anal tube as wide as high, with small teeth. Bridge of pygofer bearing a spine directed upwards. Lateral lobes of female with smooth excision. (Subgenus Eurybregma Scott). Macrocoryphe with 2 rounded, dark brown spots posteriorly and 1 spot anteriorly. Eumetope brown, with light lateral margins and dark brown stripes along them, so that there remains an equivalent light stripe between intermedial carinae. The rest of pattern as in E. pseudagropyri, but inner dark stripes of abdomen often strongly weakened in female. 3.1-4.5, macropters up to 5.4. – Amur.; C[entral] Yakutia, Transbaikal, Tuva, Altai, S Siberia, Kazakhstan, Middle Asia in mountains). – China (Xinjiang), Mongolia, C and S Europe. – In quackgrass meadows (but neither in ruderal habitats nor in fields). Late May to mid-July.
(Figs. 329: 1-9) …  E. nigrolineata

2– Anal tube very high, with strong claw-shaped teeth. Bridge of pygofer without tooth, with sagittal carina ending by a knob above. Lateral lobes of female with step. (Subgenus Priapyx Em.). Similar to E. nigrolineata in pattern, but if eumetope has a pattern, its middle field darkened. In male, pygofer large, high, compressed laterally. 2.8-4.1, macropters up to 4.4. – Mag.; C Yakutia, Altai. [p. 434] – Mongolia. – In grass meadows of river and brook flood plains, in glades. Mid-June to late July. (Figs. 329: 10-16) … E. (P.) pygalis

Molecular resources

At this time, Genbank and Bold have limited molecular resources for this genus, mostly for Eurybregma nigrolineata – this species was sequenced for 18S, 28S, CO1, WG in Urban et al. (2010).
