Name
Patagobia Schmidt & De Freina gen. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type species
Turuptiana thursbyi Rothschild, 1910.
Etymology
The name is derived from a combination of the words Patagonia and Phragmatobia.
Diagnosis
Although Patagobia shows similarities to the Holarctic Phragmatobia in some external aspects, it differs in having longer, symmetrical rami of the male antenna, ochre thoracic collar, lack of a male clasper, pale tan forewing pattern (usually), and a restricted distribution to the Chilean Andes of South America. The wing colour and pattern is also similar to Andesobia, but structurally Patagobia has a more robust build with denser thoracic vestiture, equally long posterior and anterior male antennal rami (anterior rami shorter than posterior in Andesobia), male antennal rami up to 3 × longer than antennal segment length (up to 2 × in Andesobia); 2nd labial segment elongate, 1.8 × as long as wide, 1.5 × longer than apical segment; thoracic collar contrastingly paler ochre (conconcolourous with dorsal thoracic vestiture in Andesobia); thoracic vestiture dense and pilose (sparse and shaggy in Andesobia);femur and tibia elongate, 4.5–5.6 × longer than wide (very stout, 3.0–3.5 × longer than wide in Andesobia); metatibia with two pairs of spurs (one pair in Andesobia); forewing medial line present (absent in Andesobia); postmedial line usually double (absent in Andesobia); hindwing discal spot diffuse and elongate (sharp or absent in Andesobia). The male coremata betwen the 7th and 8th sternite are moderately developed in Patagobia, very reduced in Andesobia.
Description
Male (female unknown). Head – vestiture dark brown to black, setae long; antenna bipectinate, ciliate ventrally; longest posterior rami 1.5–3.0 × segment length, longest anterior rami 1.1–3.0 × segment length; rami longest over middle third of antenna, decreasing in length toward base and apex; eye elliptical, 1.2–1.5 × as high as wide; labial palp short, not extending beyond vestiture of frons; haustellum reduced and poorly sclerotized, presumably nonfunctional. Thorax – vestiture of vertex and ventrum of thorax black brown; tegulae entirely black brown or black brown edged with yellowish brown; patagia yellowish brown or rarely black brown; leg vestiture brownish ochre, dorsum of femur yellow or red, co-varying with hindwing and abdomen ground colour; apex of prothoracic tibia with two subequal, blunt, triangular projections; mesotibia with two apical and two subapical spurs, length of apical spurs 1.5 × and supapical spurs 0.6 × tibial width at apex; two metatibial spurs, posterior spur slightly longer than anterior; metepisternum lacking microtymbals. Forewings – forewing length 12.9–13.2 mm (mean 13.1 mm; n = 4), length:width ratio averaging 2.1; ground colour pale ochre yellow but with broad, sometimes entirely confluent dark-brown transverse bands (Fig. 4c); pattern elements consisting of dark basal area and sinuous, diffuse dark-brown transverse lines (Fig. 4a) discal spot indistinct dorsally, but well defined ventrally; ventrally with bands obsolete except for marginal band. Hindwing – ground colour pinkish red or rarely yellow (Fig. 4d), with broad dark-brown marginal and costal band; well-defined brown, crescentic discal spot; similar ventrally but with discal spot better defined. Abdomen – Vestiture brownish black and pinkish red or yellow subdorsdally, ventrally with segmental margins yellowish ochre; abdomen entirely dark brown in melanic specimens (Fig. 4c). Coremata between sternites 7–8 in shallow pockets, scent scales approximately 0.5 × as long as sternite length. Genitalia – highly simplified, with large, triangular, dorsoventrally flattened uncus characteristic of subtribe; uncus 1.5 × longer than width of base, broadly joined to wide, band-like tegumen; dorsal margin of tegumen caudally recurved; valve simple and digitate, lacking processes or claspers, 1.5 × as long as uncus-tegumen complex; vinculum semicircular, saccus v-shaped, similar in length to uncus; aedeagus large, 5–6 × longer than wide, 2 × as long as width of genital capsule, curving dorsad slightly; coecum 1/10 length of aedeagus, directed slightly ventrad; vesica extremely large, diameter when inflated 2 × that of genital capsule; vesica directed right-laterad, globose, finely spiculate, with poorly differentiated basal chamber and large apical chamber (Fig. 11b).
