Ghost-moths of Trinidad and Tobago with description of a new genus and a new species (Lepidoptera: Hepialidae) Mielke, Carlos G. C. Grehan, John R. Cock, Matthew J. W. Zootaxa 2020 2020-03-27 4758 1 181 190 (Schaus, 1940) Mielke & Grehan & Cock 2020 Schaus 1940 [151,605,873,900] Insecta Hepialidae Wallacella Animalia Lepidoptera 3 184 Arthropoda species guianensis comb. nov.  ( Figs 1a, 1b, 2, 3, 4, 5, 6, 10, 11, 12, 13a, 13b, 13c, 14, 15)   Diagnosis. The single known species may be recognized using diagnostic attributes of the genus. However, it is also easily recognized by the distinctive posterior abdomen and male genitalia: i) tergal lobe spatulate on the left and digitiform on the right; ii) ventral projection of the saccus pocket-like with posterior edge serrate; iii) number of antenomeres in the male ~67. These characters are unique among all known Neotropical species.   Redescription. Male( Figs 1a, 1b, 2, 3, 4, 6, 10, 11, 12, 14). Head. Frons dark orangish-brown to brown. Antenna with ~67 antenomeres.  Thorax. Coloured as the head. Legs( Fig. 10). Epiphysis and arolium absent. Forewing length: 22–31 mm; wingspan: 44–60 mm. Forewing dorsally. Elongated, tornus not distinguished; costal margin straight, apex angle sub-obtuse [almost right angled], outer and inner margins convex. Ground colour orangish-brown to brown with four light gray transverse lines ( Fig. 3): i) proximal antemedial line almost straight; ii) distal antemedial line oblique (the most oblique one); iii) proximal postmedial line almost in parallel to the proximal antemedial line, and; iv) premarginal line straight or concave which angles outward from M 2to costal margin; lighter areas present proximally to all the lines. Stigma concolourus with lines, but not always present. Hindwing dorsally. Orangish-brown to brown, generally lighter than forewing. Forewing and hindwing ventrally. Uniformly coloured, light orangish-brown to brown, but paler and without markings. Abdomen( Figs 11, 12, 14). Dorsally as the thorax, ventrally lighter. Tergum VIII with left lobe pronounced and tapered; sternum VIII lunulate and deeply concave anteriorly, with an irregular sclerotized plate of each side posteriorly.  Male genitalia( Figs 13a, 13b, 13c, 15). Tegumen (= intermediate plate) rectangular and slightly curved inward, fused to pseudotegumen. Saccus U–shaped with robust lateral arms and with a conspicuous pocket-like posterior projection; posterior edge of the pocket V-shaped, strongly sclerotized with serrate borders. Left tergal lobe spatulate, right lobe digitiform. Pseudotegumen laterally rectangular, but forming a ring around the phallocrypt that is unfused dorso-posteriorly and strongly fused antero-ventrally, producing a tapered and projected backwards process, serrated antero-ventrally. Fultura inferior (= juxta) subrectangular, enlarged at its base. Fultura superior (= trulleum) subsquare. Valva L-shaped, digitiform, but enlarged at base; tip, base and anterior margin setose. Phallus membranous, as long the height of the genitalia when everted, with several spine-like cornuti.  Female( Fig. 4). Same pattern as the male, but with paler and longer forewing. Forewing length: 49 mm; wingspan: 101 mm.  Geographical distribution.  Wallacella guianensisis known from Trinidad, southern Venezuela, Guyana, and French Guiana ( Fig. 20).   FIGURES 7−9.  Gymelloxes juliusboosi  sp. nov.7, Male holotype (enlarged 2x): 7a, dorsal view; 7b, ventral view (NHMUK). 8, Male paratype (CGCM 35.247; enlarged 2x): 8a, dorsal view; 8b, ventral view (NHMUK). 9, Female paratype: 9a, dorsal view; 9b, ventral view (UWIZM). Scale bar = 1 cm.  Ethology. Specimens were attracted to light at dusk.   Host plant. Unknown.   Etymology. It is likely that Schaus (1940)proposed the specific name after the locality of the holotypespecimen, Guyana.  Examined material( 19 males, 1 female).  Trinidad and Tobago.  3 males, Trinidad, Off Saunders Rd, Inniss Field,  50m, MV light:  17.V.1999, M.
