Etymology

Named after our good friend, the botanist Alicia Ibañez, in memory of unforgettable field
sampling experiences in Panama.

Gall (Figs. 8D–F)

Elongate, ovate, or spindle-shaped, with a very short nipple at the apex (Fig. 8D).
Greenish when fresh; coffee brown and very glossy when dry (Fig. 8F).

• Outer shell is very thin.
• Internally, a single central larval cell is suspended by very thin hair-like filaments (Fig. 8E).
• When dry, the gall is very brittle and can be easily crushed with fingers (Fig. 8E).
• Average size: 2.5 mm long.

Externally, the gall resembles A. castroviejoi, but the inner structure is distinct:

• A. castroviejoi's gall is soft and juicy.
• A. aliciae's gall consists of radiating filaments supporting the central larval chamber.

Distribution

A. aliciae was found between 1000–2681 m a.s.l. in Chiriquí, Panama.
Galls are rare.

Biology

Only the sexual generation of A. aliciae is known, inducing galls on twigs of
Quercus salicifolia Née and likely other Quercus species (section Lobatae).

• Galls are found between December–April, during the dry season in Panama.
• Adults emerged in January and February.
