Eufroggattisca okinavensis ( Ishii, 1934)

Material studied.

Spain: • Cádiz: Jerez de la Frontera ( Zoobotánico de Jerez ): 2 ♂ + 3 ♀ ex., Í. Sánchez leg. and MNCN_Ent 235061 deposit., 7-XII-2018, 82 m a. s. l, found dissecting syconia of Ficus microcarpa (36.689315, -6.150638) . • Alicante: San Vicente del Raspeig ( Universidad de Alicante ): 10 ♀ + 10 ♂ ex., J. M. Royo leg. and AC deposit. 19-V-2024, 92 m a. s. l, found dissecting syconia of Ficus microcarpa (38.384264, -0.512455). See Fig. 1 G .

Ecological remarks.

Large galler in syconium of Ficus microcarpa . In Greece, Eufroggattisca okinavensis was repeatedly recorded from the same syconia as Meselatus bicolor , whose large galls suggest a possible host-parasitoid or inquiline relationship ( Wang et al. 2015 b; Koutsoukos et al. 2024 b). This association raises the possibility that M. bicolor is also present in Spain, although its presence remains unconfirmed.

Distribution.

Originally from eastern Asia ( China, Japan and Taiwan) and Australia ( van Noort and Rasplus 2024). It was reared from figs of F. microcarpa collected in Málaga ( Spain) in 2018 and cited from Spain as Eufroggattisca sp. ( Demetriou et al. 2023).

Short description.

The species exhibits the following combination of characters: Head with occipital carina. In male petiole distinct, only slightly transverse, and pronotum long, much narrower than mesoscutum. Scutellum with two pairs of bristles ( Bouček 1988). Female with gaster petiolated, either broadly convex or even slightly compressed from side-to-side. Body yellowish or brownish. This species present head and thorax mainly smooth, with sparse long setae, only rarely with some punctures sublaterally on thoracic dorsum. Notauli, usually formed by a line of punctures ( Feng and Huang 2010). Both sexes winged, this is true for this species and also for many species in Epichrysomallidae , but not in general Epichrysomallidae because of the fact that several species have apterous males.
