Description. Body ( Figs. 7–8 View Figs ): stout, broad, parallelsided in dorsal view; length 2.5– 3.4 mm; width 1.3–1.8 mm. Integument black, broadly exposed, sparsely clothed with setiform fuscous scales and broader, more abundant, pallid cretaceous scales. Head: vertex minutely punctate, finely granulate, with sparse, narrow, cretaceous scales. Rostrum: distinctly, evenly curved from base to apex; proximal portion rugose, glabrous; distal portion rugulose, punctulate, glabrous. Antenna: funicular segments with narrow, setiform scales; basal segment of club ca. 1/3 length of club, densely setose except at base. Prothorax: pronotum densely, coarsely punctate, without middorsal carina; long, slender, cretaceous scales predominant laterally, slightly broader scales forming narrow middorsal vitta, shorter, narrower cretaceous scales predominant laterally on dorsum; mesocoxae separated by distance ca. 0.3 3 width of one mexocoxa. Elytra: broad, slightly wider at humeri, subparallelsided in dorsal view, convex on disc and strongly rounded posteriorly in lateral view; striae slightly impressed, each puncture with one small cretaceous scale; interstriae subequal in width and slight convexity, with uniform vestiture of small, sparse, cretaceous scales; sutural interstriae not prominent. Scutellum : with dense cretaceous scales. Pygidium : punctate. Abdomen: sterna 1–4 with narrow, pallid scales laterally, with sparser, narrower scales medially; sternum 5 not impressed medially. Legs: profemur slender ( Fig. 14 View Figs ), unarmed; protibia narrow, straight, with slight innermarginal prominence in basal 1/4 and with one slight preapical prominence; protibial uncus slender, curved, acute; metatibia with outer margin straight, inner margin slightly prominent in basal 1/4, not notably concave in apical 3/4, without preapical convexity ( Fig. 14 View Figs ); metatibial mucro straight, subacute, oblique in lateral view ( Fig. 14 View Figs ); tarsal claw long, slender, with blunt prominence ( Fig. 17 View Figs ) or short, slender tooth arising from inner margin, well distad of base (cf. Fig. 16 View Figs ). Male Genitalia ( Fig. 24 View Figs ): median lobe of aedeagus evenly, gradually narrowed to bluntly rounded apex in dorsal view; endophallus unarmed.
Plant Associations. The only indication of a host relationship for M. falli is a label: ‘‘ex Artemisia . ’’
Remarks. Magdalinops falli resembles Epimechus mimicus Dietz. Both species have dark integument broadly exposed between sparse, narrow scales, the rostrum long and slender, strongly curved, slightly more strongly so basally, and the antennal funiculus 7segmented. Magdalinops falli is larger, however, has the rostrum broader at the base and more narrowed apically in lateral view, and lacks the apicomedian prominence of the median lobe of the aedeagus and the endophallic transfer apparatus exhibited by E. mimicus . Furthermore, the tarsal claws of M. falli are longer and more widely divergent and have a small, acute basal prominence ( Fig. 17 View Figs ) or slender tooth (cf. Fig. 16 View Figs ) that is lacking in E. mimicus . The tarsal claws of M. falli are long, slender, and widely divergent as in M. alutaceus (cf. Figs. 16–17 View Figs ). The claws of M. alutaceus have a uniformly slender, acute basal tooth, whereas the claws in M. falli vary—in some the slender, acute tooth of the claw is indistinguishable from that of M.

however, is distinguished by its stouter, broader body form (cf. Figs. 5–8 View Figs ), rugosepunctate rather than smooth, sparsely punctate rostrum, subcarinate rather than obsolete dorsal margin of the lateral rostral groove, and by the narrower pronotal and elytral scales that leave the integument more broadly exposed.
The species is named for Henry Clinton Fall (1862–1939) in honor of his many contributions to the study of the Curculionidae . The Fall Collection at the MCZC also contains some of the earliest collected specimens of this species.
