Trassedia luapi Cancemi 1996 Diagnosis Trassedia luapi shares the following characters with T. yanegai and T. australiensis: short setae on the dorsal region of the cranium (shorter than the diameter of the median ocellus; Fig. 3C and D); reduced anterior ocellar fovea that do not extend to the antennal scrobe (Fig. 3C and D); a punctate ocular impression along the inner orbit (io: Fig. 3C and D); and a wide Waterston’s evaporatorium that reaches the lateral 1/3 of the tergite (wop: Fig. 4A and B). Trassedia luapi differs from T. yanegai by the preoccipital sulcus not widening gradually anteriorly (pof: Fig. 3C) and by the presence of the notaulus, scutes on the vertex, a foveolate sternaulus (ster: Fig. 5C) and large eyes (HW/IOS = 3.7, Fig. 3C). The female pedicel and F1 are brown and F2–F4 are whitish in T. yanegai, while the female pedicel and F1–F3 are yellow and F4–F9 are dark brown in T. luapi. Trassedia luapi differs from T. australiensis in cranium shape (cranium as long as wide in dorsal view in T. australiensis and 1.4× as wide as long in T. luapi), POL:OOL ratio (POL 2× as long as OOL in T. australiensis and equal to OOL in T. luapi), the length of the harpe (harpe 2× as long as the gonossiculus in T. australiensis and 1.5× as long as the gonossiculus in T. luapi) and the position of the distal sensilla of the gonossiculus (sensilla closer to the distal margin than to the proximal margin of the gonossiculus in T. luapi and equidistant from both margins in T. australiensis). Description Body length: 1.80–2.90 mm. Color hue pattern female: brown, F1–F3, legs yellow. Color intensity pattern female: F4–F9 darker than cranium, scape, pedicel, mesosoma and metasoma. Color hue pattern male: ochre, legs, scape, pedicel, F1 yellow. Structure of scutes on head and mesosoma: Scute surface on head and mesosoma flat, scutes indistinct. HW:HH = 0.9–1.3. Head: HW/IOS Female: 2.5–2.7. HW/IOS Male: 2.2. Maximum eye diameter versus minimum eye diameter: 1.1–1.3. Interommatidial seta length: Interommatidial seta length ... |
