mericarp. This species was described by E. Sylvén from the type-locality Algarve, Albufeira

Dasineura fraxini (Bremi, 1847)
Larvae cause swellings of the mid-vein on the leaflets of Fraxinus excelsior L. (Oleaceae).
Occurrence: scarce (Fig. 41); Engolasters and Sispony (Andorra, 1992-1993), Matadepera
(Barcelona, 1980) and Montseny (Barcelona, 1995), leg. Pujade-Villar. Reference: SKUHRAVÁ
et al. (1996). Distribution: European.
Dasineura galiicola (F. Löw, 1880)
Larvae form artichoke-shaped galls on Galium uliginosum L. (Rubiaceae). Occurrence: very
scarce (Fig. 42); Matadepera (Barcelona, 1987) leg. Pujade-Villar. References: SKUHRAVÁ
et al. (1996). Distribution: Euro-Siberian.
Dasineura gleditchiae (Osten Sacken, 1866)
Larvae change into galls the leaflets of Gleditsia triacanthos L. (Caesalpiniaceae). Occurrence:
very scarce (Fig. 42). Reference: ESTAL et al. (1998). Distribution: Nearctic, immigrant
in Europe.
Dasineura halimii (Tavares, 1902)
Larvae change terminal or axillar leaf buds in fusiform galls on Halimium ocymoides (Lam.)
Willk. in Willk. & Lange (= H. heterophyllum Spach) and H. alyssoides (Lam.) (= H. occidentale
WK) (Cistaceae). Each gall with solitary red larva. Occurrence: medium frequent
(Fig. 43). References: TAVARES (1902d, 1905a, 1909, 1919), COGOLLUDO (1921). Distribution:
Mediterranean, endemic to the Iberian Peninsula.
Dasineura herminii (Tavares, 1902)
Orange coloured larvae cause globular galls on stem tips of Halimium alyssoides (Lam.) (=
Halimium occidentale WK) (Cistaceae). The gall is formed of many deformed leaves and is
inhabited by many larvae. Occurrence: medium frequent (Fig. 43). References: TAVARES
(1902d, 1905a, 1909, 1919), COGOLLUDO (1921). Distribution: Mediterranean, endemic
to the Iberian Peninsula.
Dasineura hygrophila (Mik, 1883)

L.), G. elodes Hoffgg. (Rubiaceae). Occurrence: very scarce (Fig. 44). References: TAVARES
(1902b, 1905a). Distribution: Euro-Siberian.
Dasineura hyperici (Bremi, 1847)
Larvae cause leaf bud galls on Hypericum undulatum Schousb. (Hypericaceae). Occurrence:
very scarce (Fig. 44). Reference: TAVARES (1902a). Distribution: European.
Dasineura ilicis (Tavares, 1919)
Perrisia ilicis Tavares, 1919
Larvae live on leaves of Quercus ilex L. (Fagaceae), probably as inquilines or comensals of
larvae of Contarinia luteola Tav. Occurrence: scarce (Fig. 45). References: TAVARES (1919,
1920). Distribution: Mediterranean, endemic to the Iberian Peninsula.
