Trassedia yanegai Mikó and Trietsch sp. nov. (Zoobank LSID: urn:lsid:zoobank. org:act: 53D5E575-4ED3-4146-A7F2-19ECF032846E) Diagnosis Trassedia yanegai shares the short setae on the dorsal region of the cranium (shorter than the diameter of the median ocellus; Fig. 3C and D), the reduced anterior ocellar fovea that does not extend to the antennal scrobe (Fig. 3C and D), the punctate ocular impression along the inner orbit (io: Fig. 3C and D) and a wide Waterston’s evaporatorium that reaches the lateral 13 of the tergite (wop: Fig. 4A and B) with T. luapi and T. australiensis. Trassedia yanegai differs from these species in the lack of the notaulus, the lack of scutes on the vertex, the anteriorly gradually widening preoccipital sulcus (pof: Fig. 3C), the foveolate sternaulus (ster: Fig. 5C) and the 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. Description Body length: 3.95 mm. Color hue pattern female: cranium, mesosomablack, F5–F9 black, F2–F4 white, scape, legs, pedicel, F1 ochre. Color intensity pattern female: pedicel, F1, fore leg, mesocoxa darker than rest of middle leg, hind leg, scape. Structure of scutes on head and mesosoma: scute surface on head and mesosoma flat, scutes indistinct. Head: HW:HH = 1.1. HW/IOS Female: 3.8. Maximum eye diameter versus minimum eye diameter: 1.2. Interommatidial seta length: interommatidial seta length less than facet diameter. Occipital carina medially: continuous medially. Seta length on dorsal region of cranium versus diameter of median ocellus: shorter. Scutes on vertex count: absent. Preoccipital furrow anterior extension: adjacent anteriorly to the posterior margin of the median ocellus. Preoccipital furrow anterior region versus posterior region sculpture: posterior region crenulate, anterior region smooth or finely reticulate. Preoccipital furrow anterior region width versus posterior region width: wider anteriorly than ... |
