Macroglenes paludum (Graham)


Macroglenes paludum (Graham)  

(Figs 19, 29)

Pirene paludum Graham, 1969: 345   –346. Macroglenes paludum   ; Hansson, 1991: 53.

Diagnosis. Body with conspicuous green metallic color; clypeal margin not incised (cf. Figs 1–2); only F 5 large, with sensilla (cf. Fig. 33); mesosoma distinctly convex (cf. Fig. 10); pecten hardly developed (cf. Fig. 13); forewing with large patch of hairs on distal half of basal cell (Fig. 19) and without bare area between R and apical margin of wing; ovipositor long and hypopygium removed from tip of gaster (Fig. 29). Male with eyes normal, scape not inflated and distinct constriction between first two claval segments.

Material examined. HOLOTYPE (Ψ): U.K.: ‘ Type Hym: 1245 Pirene paludum Graham, Hope Dept.   Oxford’, ‘ Scotland, MP. Killin, 7. 7. 1952 M. de V. Graham’, ‘ Pirene paludum   sp. n. Holotype Ψ, M. de V. Graham det. 1968 ’ ( OUMNH).

Bouček 1986 ’, ‘ Suisse: Basel, Phalaris   midge, VII. 85, CIBC’ ( BMNH); 3 ɗ idem, ‘ 17606 2.’ ( BMNH); 2 ɗ ‘ Pirene   plaudum Grah., det. Z. Bouček 1986 ’, ‘ Switzerland, Büren-a-Aare’, ‘VII-VIII. 85, ex wheat midge’, ‘C.I.B.C No 2; C.I.E A 17606 View Materials ’ ( BMNH); 4 Ψ, 2 ɗ ‘Suisse-Vaud, Préverenges, 24 VI 56, Cl. Besuchet’, ‘ Macroglenes paludum Grah.   det. H. Baur 2009 ’ ( MHNG).

Comments. A rather rare or local species, apparently confined to North-Western Europe.

Distribution. Netherlands, Sweden, U.K. ( Noyes 2003); previously unrecorded from Czech Republic and Switzerland. The species was also recorded from China by Huang & Xiao (2005), but the drawing of the forewing suggests that a different species may be involved. Unfortunately, no material was available to resolve this.

Hosts. In the BMNH there are 15 Ψ and 19 ɗ reared from ‘ Phalaris   midge’ and 2 ɗ reared from ‘wheat midge’, all from Switzerland (see above). Graham (1969) stated that the holotype was ‘swept in a marshy place’ [p. 346] (hence the name paludum   ). According to the Flora Europaea Database there are five species of Phalaris   ( Gramineae   ) in Europe. Of these only P. arudinacea   (reed canary grass) is recorded from both Britain and Switzerland, while the non-native P. canariensis   is recorded from Switzerland. Thus, it can be concluded that the host is probably a midge developing in P. arudinacea   . Two midges ( Diptera   : Cecidomyiidae   ) attacking P. arudinacea   have been described: Mayetiola phalaris Barnes, 1928   and Epicalamus phalaridis Sylven, 1997   . According to the Fauna Europaea Database the first species occurs in Britain, Czech Republic and Germany, while the latter in Sweden. Thus, it can be concluded that M. paludum   most probably attacks Mayetiola phalaris   on Phalaris arudinacea   . The records from the ‘wheat midge’ ( Sitodiplosis mosellana   or Contarinia tritici   ) need to be confirmed.
