Diagnosis

Specimens of Schacontia chanesalis are best distinguished from those of Schacontia medalba by the male genitalia, specifically a more sinuate valva and more denticled or rugose (as opposed to naked) intrasaccular process. The valvae are less conspicuously lobate than in Schacontia umbra (below). Forewing pattern somewhat variable, as in Schacontia medalba, but antemedial area more often traversed by white bar originating at scapula, enhancing the baso-costal patch.

Re-description

(Fig. 2). Forewing length: 4.5–9.0 mm. Head - Ocelli and chaetosemata absent; proboscis reduced. Labial palpi porrect, extending slightly beyond clypeus. Frons conical; vertex and frons grayish brown, intermixed with white scales medially and along anterior bases of antennae. Thorax - Prothoracic collar light gray intermixed with gray-brown and white scales. Tegula and mesoscutum mostly gray, intermixed with light-gray and/or grayish-brown scales, the posterior apex of tegulae pale gray. Legs predominantly white, gray shading throughout foreleg; female with one pair of hind tibial spurs (medial pair absent). Forewing. Baso-costal triangle flanked by white scaling towards inner margin and in medial area, which is outwardly shaded brown (suffused with white basad). Postmedial area (between postmedial line and subterminal line) grayish brown. Subterminal line white; terminal line black, interrupted. Marginal scales brown. Basal area grayish brown traversed by a white band. Fringe scales light gray. Hindwing. Ground color white/very light gray, darker postmedially; postmedial lines grayish brown, white distally, conspicuous and common with FW. Subterminal area shaded darker brown; fringe white. Sc+R1 and Rs anastomosed slightly beyond dilated base of former. Male and female acanthae of frenulum fused from near base to apex to form one bristle. Abdomen - Ground color mostly dark gray intermixed with gray and light-gray scales above, white on undersurface. Tympanal organs (Fig. 22). As above for medalba group, vide supra. Male Genitalia (Figs 39, 40) - Tegumen divided dorsally into two dihedral or hemi-spherical “bubbles” that meet at a central sulcus, which divides anterior to base of uncus and forms a Y-shaped strut. Teguminal sulcus long, extending length of two teguminal lobes, such that anterior margin of tegumen appears emarginate, but not deeply invaginated. Uncus oblong, mucronate or miter-like, culminating in a distinct tip; concave or spatulate, setose on inner (ventral) surface. A membranous, more or less circular region at base of uncus positioned directly above (dorsal to) finger-like projection of gnathos, which also comprises a floating sub-tegumenal plate with four arms. Finger-like process arises from center of gnathos; dorsal pair of arms, which meet at juncture of uncus and tegumen, appearing to fulfill traditional description of gnathos by enveloping the anal tube, and the anterior pair extending ventrolaterally towards the vinculum, resembling a wishbone. Gnathos thus appears as a subtegumental (ventrad) suspension. Valvae reduced, broadly emarginate, bilobed; intrasaccular process a simple flange, denticled or rugose; subapical setal cluster near saccular margin. Costa robust, curved, appearing to arise near the respective vincular terminus. Juxta horseshoe-shaped, the base wider than the lateral “arms.” Phallus simple, moderately sclerotized throughout; cornuti absent. Female Genitalia (Fig. 41) - Papillae anales appressed; antrum apparent, chalice-like; ductus bursae short; corpus bursae elongate, without signa, caeca, or appendix bursae; ductus seminalis originating from posterior portion of corpus bursae. Ostium bursae with membrane between seventh and eighth segments.

Biology

Larvae have been reared from Podandrogyne decipiense (Capparaceae) (D. Janzen, pers. comm.).

Distribution

Mexico, Guatemala; Costa Rica; Venezuela.

Immature stages

Unknown.

Variation

In size, with Mexican specimens appearing smaller in wingspan (FW length 4.5–7.0 mm) than Central American specimens.

Remarks

It is with some trepidation that we synonymize both replica and especially pfeifferi with chanesalis. Pfeifferi in particular was, until this work, the only Schacontia for which a detailed description had been published, and its continental separation from the type locality and primary distribution of chanesalis might suggest the potential for as yet unrecognized diagnosable species.
