Name
Caledonotrichia ouinnica Wells & Johanson & Mary-Sasal, 2013 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnosis
Males are recognised by the presence of a tiny jet black spot on the forewing between veins R and M, formed by a cluster of androconial scales; but it is particularly distinguished from all other species by maxillary palps with dense brush of elongate setae on the first segment and bristle-like setae on other segments which give the palps a bottlebrush-like appearance (Fig. 15), including the otherwise closely similar Caledonotrichia minor which has maxillary palps of the usual form with fewer and shorter straight setae, the forewings are less attenuate apically and the area of scales over the fork in M larger.
Description, male
Head rounded in dorsal view, as in Caledonotrichia capensis sp. n. (Fig. 1). Forewing (Fig. 6) length, 2.2–2.4 mm (n=5); wing acute apically; small cluster of slender jet black androconia proximally. Maxillary palps densely hairy (Fig. 15), with basal 2 segments short and rounded, segment 2 bearing a tuft of long setae, segment 3–5 cylindrical, segment 3 length almost 3× maximum width, segment 4 length about 2× width, segment 5 length approximately 6× width. Antennae with 23–24 flagellomeres, median flagellomeres slender with length around 4–6× width.
Genitalia (Figs 36, 37, 45). Abdominal segment IX rounded anteriorly, sternite slightly cleft medially on posterior margin, a row of elongate setae on distal margin (arrow in Fig. 36). Tergite X tapered to broadly rounded apex. Each gonopod with ventral lobe club-shaped, dense short setae towards tip, dorsal lobe rectangular. Sclerotised rods of subgenital process in ventral view simple, rounded apically. Phallic apparatus elongate, almost length of abdominal segments VII–IX, without associated parameres.
