Diagnosis

Alloxysta llumae sp. nov. is easily differentiated from all other species of Alloxysta by the R1 vein nearly touching Rs. It is morphologically similar to A. salicicola Belizin, 1973 , but differs, in addition to the alar character mentioned, by the length of flagellomeres (F1 and F2) being longer in A. salicicola than in A. llumae . Also, the radial cell of A. saliciola is bigger (2.6) than in A. llumae (2.3).

Etymology

This species is dedicated to the daughter of the first author, Llum Garrido Ferrer.

Material examined

Only known from the holotype female.

Holotype

CZECH REPUBLIC • ♀; near Litoměřice ; 24 Jun. 1957; P. Stary leg.; 57-i- 287; UB.

Description

LENGTH. Female: 1.4 mm. Male unknown.

COLOURATION. Head, mesosoma and metasoma brown. Scape, pedicel, F1–F2 dark yellow, F4–F11 yellowish brown. Legs yellow and veins yellowish brown.

HEAD. Transversally ovate, smooth, and shiny, slightly wider than high in frontal view. Few scattered setae above toruli. Scattered setae on vertex and many setae on face. Transfacial line 1.1 times the height of compound eye. Malar space 0.6 times the height of compound eye.

ANTENNA. Female: 13-segmented, filiform. All antennomeres covered with sparse setae. F1–F2 smooth and thinner than remaining flagellomeres, F3–F11 with placodeal sensilla and club shaped. Antennal formula: 2.5 (1.9); 4.0 (0.9); 2.8 (1.0); 2.7 (1.1); 3.0 (1.2); 2.7 (1.1), F5–F11 subequal in length, width, and shape ( Fig. 1D ).

MESOSOMA. Pronotum completely covered by scattered setae, with two thin carinae sometimes difficult to see under the pubescence ( Fig. 1B ). 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 completely covered by abundant pubescence, without carinae present ( Fig. 1C ).

FORE WING. Longer than body, 1.4 times as long as mesosoma and metasoma together. Covered with dense pubescence; marginal setae present and very long ( Fig. 1A ). Partially open radial cell (nearly closed), 2.3 times as long as wide in female. R1 short and curved; Rs long and slightly curved nearly reachn R1 ( Fig. 1F ).

METASOMA. Anterior part with an incomplete ring of setae, glabrous at centre, wider laterally. Metasoma smooth and shiny, T3 and T4 clearly distinguished.

Distribution

Czech Republic (Litoměřice).

Host

Unknown.
