Fustis View in CoL s-forma Fibiger, new species
( Plate 6 View PLATE 6 , figure 5; male genit. plate 16, figure 1)
Material examined. Holotype: male, Thailand NE, ca. 5 km NE junction road 1081–1307 towards Ban Nam Lee Pattana , 28.xi.2003, leg. L. Peregovits, M. Földvári & Á. Körösi, genit. prep. 6070 M. Fibiger, coll. HNHM.
Diagnosis. Imago (external). Wingspan: 13.5 mm (apo.).
Head, patagia, anterior part of tegulae, prothorax, basal part of costa, triangular patch of medial area, and terminal area, including fringes: black.
Forewing: long and narrow, with pointed apex; brown ground colour (apo.).
Abdomen: dark grey; with dorsal tuft on basal segment.
Crosslines: untraceable, except subterminal line weakly marked, beige, and terminal line marked by black interneural dots.
Reniform stigma: beige, ovoid, black outlined.
Hindwing: grey; with narrow brown terminal line and indistinct discal spot; fringes basally beige, distally grey.
Underside: forewing grey-brown; hindwing light grey, with discal spot.
Male genitalia. Tegumen-fultura superior: fused, with diaphragm medially forming a tube (apo.).
Vinculum: two-branched; centre one barlike; posterior one branchlike, not curved.
Saccus: relatively long; broadly U-shaped.
Valvae: slightly asymmetrical.
Ampulla: bilobed; slightly asymmetrical; lobes tapered strongly from subapically twice as broad and rounded ventral part to slightly shorter dorsal, rounded tip; dorsal lobe narrow, straight; ventral lobe broad, curved (apo.)
Digitus: rather large, platelike, broadly quadrangular.
Juxta-anellus plate: inseparable (phallus on left side); base strongly asymmetrical, with narrow processes; medially with extremely long, heavily sclerotised, free, tapered, and S-curved process; with curved, setose, pointed tip (apo.).
Phallus: coecum short and broad, smoothly rounded; broadest by ductus ejaculatorius; there with short forewardly directed process (a stop-function connected with juxta-anellus ventral processes); slightly upturned and tapered outwards; tip ventrally with small hook (apo.).
Vesica: armed with a small and short, heavily sclerotised rectangular plate (apo.).
Differential diagnosis. F. s-forma differs from other Fustis species in:
- brown ground colour;
- fused tegumen-fultura superior plate;
male genitalia, in
- shape of ampulla, especially narrow dorsal arm;
- long, S-formed, setose, pointed anellus;
- phallus short, slightly upturned, with ventral small hook at tip; and
