Figs. 6, 13, 17, 27, 31, 38, 42  
 Etymology. Named meridionalis = southern, in reference to its most southerly distribution for the genus.   
 Type material. Total: 2 ♂♂. Holotype ♂, Honduras, Comayagua Dept., cloud forest stream, ca. 10 mi SW of Siguatepeque, 14°34' 2"N, 87°56'54"W, 1620 m, 25 v 1972, leg. E.W. Stiles, (USNM). Paratype: same data as holotype, 1 ♂ (DRP)   
 Description. Holotype dimensions: Hw 36.0; abdomen 40.0; total length 51.0. Head of male holotype as in holotype of A. nataliae but with narrow black border around labrum and with ventral margin of anteclypeus infused with yellow.   
 Prothorax as in A. nataliae but with pale green pleural spots of middle lobe extending dorsally toward, but not touching, midline; hind lobe entire, raised, lateral lobes vertical, semicircular, and continuous with smaller irregular v-shaped middle lobe (Figs. 6, 13).   
 Synthorax as in A. nataliae but with second and third lateral stripe on middle of mesepimeron separated into a series of irregular spots on mesinfraepisternum; first lateral stripe reduced, its upper portion limited to upper fourth of mesepisternum followed ventrally by a small, elongate black spot ending at mesinfraepisternum; second (interpleural) thoracic stripe abbreviated and confined to metapleural fossa and small elongate spot above metastigma, third stripe bordering posterior margin of metepimeron. Coxae and legs as in A. nataliae but femora dark brown; Wings (Fig. 17) hyaline; Ax Fw 8 (left):7 (right); Hw 7:7; Px Fw 34:35; Hw 26:28. Abdomen as in A. nataliae but S3–6 with only a basal pale spot laterally, these becoming successively smaller on more terminal segments; S7 black, dorsum of S8–10 pale blue, a thin mid-dorsal black line on S10, its postero-dorsal margin with a narrow median notch half as long as segment. Genital ligula as in A. nataliae (Figs. 22–23). Cercus black, slightly longer than S10, robust, spinulose dorsoexternally, in dorsal view fusiform with apex rounded and armed with a small internal anteapical scalariform tooth, medial surface anterior to tooth rugosely concave (Figs. 27, 38); in lateral view cercus robust, linear, roughly parallel from base to apex, slightly swollen medially (Fig. 31). Paraproct about 0.70 length of cercus, its tip in lateral view slightly directed dorsally, base in dorsal view (Fig. 38) inflated main branch short, parallel its apex slightly inflated, quadrate.   
 Variation in paratypes. paratype male like holotype but with dark lateral thoracic stripes more extensive and complete.   
 Dimensions. Males (n = 2, including holotype; means in parentheses): Hw 36.0 (37.5); abdomen 40.0 (41.5); total length 51.0 (52.9).   
 Distribution. Known only from the type locality (Fig. 42).   
 Diagnosis. Amphipteryx meridionalis is diagnosed in the key to males and under A. nataliae.
