Diagnosis
Alloxysta poli sp. nov. is characterized by the presence of pronotal carinae and a propodeal plate, radial cell partially open, 2.3 times as long as wide, rhinaria and club begin on F2, F1 longer than pedicel and subequal to F2, F2 longer than F3. It is closely related to A. macrophadna (Hartig, 1841) but they can be differentiated by the short radial cell, 3.0 times as long as wide in A. macrophadna while it is 2.3 times as wide in A. poli.
Etymology
This species is dedicated to the son of the first author, Pol Garrido Ferrer.
Material examined
Known from seven males and twenty-eight females.

Description
LENGTH. Female: 0.8–0.9 mm. Male: 0.7–0.9 mm.
COLOURATION. Head yellowish brown, mesosoma and metasoma brown. Scape, pedicel, F1–F3 dark yellow, F4–F11 yellowish brown. Legs yellow and veins yellowish brown.
HEAD. Transversally ovate, smooth, and shiny, slightly wider than high in front view. Setae below and between toruli, few scattered setae above toruli. Scattered setae on vertex and many setae on face. Transfacial line 1.2 times the height of compound eye. Malar space 0.3 times the height of compound eye.
ANTENNA. Female: 13-segmented, filiform. All antennomeres covered with sparse setae. F1–F3 smooth and thinner than remaining flagellomeres, F4–F11 with placodeal sensilla and club shaped. Antennal formula: 2.0 (1.3); 2.6 (0.7); 2.8 (0.8); 2.5 (0.8); 2.4 (1.0); 2.4 (1.1), F5–F12 subequal in length, width, and shape (Fig. 3F). Male: 14-segmented, filiform. All antennomeres covered with sparse setae. F1 smooth and thinner than remaining flagellomeres, F2–F12 with placodeal sensilla and club shaped, F2 and F3 bowed. Antennal formula: 2.0 (1.5); 3.0 (1.0); 3.5 (1.2); 3.2 (1.2); 2.5 (1.1); 2.5 (1.1), F5-F12 subequal in length, width, and shape (Fig. 3E).
MESOSOMA. Pronotum covered by sparse setae, being less in the distolateral corners and abundant in the anterior margins, with two long and think carinae clearly visible (Fig. 3C). Mesoscutum smooth and shiny, round in dorsal view with few scattered setae. Scutellum smooth and shiny with scattered setae, more abundant on apex of scutellum. Propodeum covered by abundant setae, without carinae and without setae where carinae usually present (Fig. 3D).
FORE WING. Longer than body, 1.5 times as long as mesosoma and metasoma together. Covered with dense pubescence; marginal setae present and very long. Partially open radial cell, 2.3 times as long as wide in female paratypes (Fig. 3A), 2.8 times in male, type and paratypes (Fig. 3B). R1 short and curved; Rs long and slightly curved.
METASOMA. Anterior part with an incomplete ring of setae, glabrous at centre, wider laterally. Metasoma smooth and shiny, T3 and T4 clearly distinguished.
Distribution
Pinar del Río (Cuba), Zhoř (Czech Republic) and Tatry (Slovakia).
Host
Emerged from Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) on Psidium guyava L. (Myrtaceae) and, Betulaphis sp. and Euceraphis sp. (Hemiptera: Aphididae) on Betula L. (Betulaceae).
