Arytinnis prognata (Loginova) comb. n.

(figure 17A)

Arytainilla prognata Loginova, 1976: 28 ; Hodkinson and Hollis, 1987: 42.

Adult

Colour. Mid-green to yellow green; forewing clear, veins uniform light brown. Description. Loginova (1976).

Nymph

Colour. First to second instars orange-red with black tergites, 3rd–5th instars bright green, grey-green or cream, with or without black tergites.

Fifth instar structure. Antennal segments seven.

Fifth instar measurements. (specimens 5) BL: 1.35–2.03; BW: 0.85–1.08; WL: 0.5–0.54; CPL: 0.42–0.49; CPW: 0.57–0.67; RW: 0.16–0.18; HW: 0.57–0.67; AL: 0.82–0.9.

Fifth instar chaetotaxy. Head setae simple; ocular seta simple, dark, conspicuous; primary post-ocular seta narrowly or distinctly capitate; secondary post-ocular seta simple. Dorsal thoracic setae simple, short with few longer. Forewing and hindwing pads each with one apical macroseta, distinctly capitate; hindwing pad apical seta paired with small simple seta; proximal setae indistinct from simple microsetae scattered on the wing pad surfaces. Dorsal abdominal pre-caudal macrosetae on anterior tergites, long simple, caudal plate macrosetae absent; sectasetae four pairs; marginal abdominal setae (other than sectasetae) one pair (first position), distinctly capitate; pleurite setae paired simple, occasionally slightly capitate. Legs with simple setae only.

Host plant. Teline microphylla .

Distribution. Canary Islands: Gran Canaria.

Notes. In this study, A. prognata was found to be restricted to southern populations of the host plant where the habitat is xerophytic. In all cases it was found to be sympatric with A. equitans and in April, more abundant than this species on the most southerly host population sampled. However, it was absent from collections made from this same host population later in July, when only A. equitans was found. This suggests that these species develop at different times, with A. prognata developing earlier than A. equitans .

Biology. Small nymphs were observed on the corolla and larger nymphs on the pedicel of developing flowers.
