Alloxysta piceomaculata (Cameron, 1883) stat. rev. Fig. 5 Allotria piceomaculata Cameron, 1883: 367. Dilyta piceomaculata − Kieffer 1900: 114. Alloxysta (Alloxysta) piceomaculata − Dalla Torre & Kieffer 1902: 39. Alloxysta piceomaculata − Hellén 1963: 13. Type material Holotype ♀, with the following labels: “ Holotype ” (round label with red margin), “Cameron 96─76. Dumfries”, “Dumfries, piceomaculata” (handwritten), “ piceomaculata Cam ” (handwritten), “ Holotype ♀ Allotria piceomaculata C. det. J. Quinlan, 1973” (handwritten), “B.M. TYPE HYM. 7.127”, “ Alloxysta piceomaculata (Cameron, 1883) det. M. Ferrer-Suay 2012”. Redescription COLORATION. Head, mesosoma and metasoma yellowish brown. Scape, pedicel and F1-F2 dark yellow; F3-F11 brown. Legs and veins dark yellow. HEAD. Transversely ovate, smooth and shiny, wider than high in front view. With setae below and between toruli and a few setae above toruli. With few scattered setae on vertex and with many setae on face. Transfacial line and malar space cannot be measured due to the position of the type specimen. ANTENNA. Female: 13-segmented, filiform. All antennomeres covered with sparse setae. F1-F3 thinner and smoother than remaining flagellomeres; F4-F11 club-shaped, with rhinaria. Pedicel 1.9 x as long as wide; F1 1.4 x as long as wide; F2 2.4 x as long as wide; F3 2.6 x as long as wide; F4 2.1 x as long as wide. F1 1.2 x as long as pedicel; F1 1.4 x as long as F2; F3 1.1 x as long as F2; F3 subequal to F4; F4-F11 subequal in length, width and shape (Fig. 5D). Male unknown. MESOSOMA. Pronotum covered by abundant setae, with two long and thick, clearly visible carinae (Fig. 5F). Mesoscutum smooth and shiny, round in dorsal view, with scattered setae. Scutellum also smooth and shiny, with few scattered setae, abundant on apex of scutellum. Height of mesopleural triangle along anterior margin 1.3 x height of mesopleuron. Propodeum covered by abundant setae, propodeal carinae absent (Fig. 5C). FORE WING. Longer than body, 1.8 x as long as mesosoma and metasoma together (Fig. 5A), covered with dense pubescence; marginal setae present. Open radial cell, 2.8 x as long as wide. R1 short and straight; Rs long and slightly curved (Fig. 5B). METASOMA. Anterior part with an incomplete ring of setae, glabrous at centre, wider laterally. Metasoma smooth and shiny, T3 and T4 clearly distinguished. Remarks The type series of Alloxysta piceomaculata is represented by the lectotype female and one paralectotype male. This species was synonymized with A. macrophadna (Hartig, 1841) by Fergusson (1986). After studying the type material, we found it was different from A. macrophadna and therefore it is here considered a valid species. This species is similar to Alloxysta nigrita (Thomson, 1862) in having a completely open radial cell, pronotal carinae present, propodeal carinae absent, and flagellomeres club-shaped and with rhinaria from F4. However, they can be differentiated by the relative length/width of F1: 1.4 x as long as wide in A. piceomaculata, but 4.4 x in A. nigrita; ratio between the lengths of F3 and F4: F3 subequal to F 4 in A. piceomaculata but longer than F 4 in A. nigrita.
