The triangular inferior appendage with a rounded apex, in lateral view, resembles those of  M. bracuiSantos,Takiya & Nessimian and several members of the  Metrichia neotropicalisgroup (Flint 1983), such as  M. patagonicaFlint. However, the phallus of  M. leahaesp. nov. has a pair of apical spines, absent in those species with a triangular inferior appendage, but similar to those seen in  M. longitudinisBueno-Soria,  M. gombosa Olah& Johanson, and  M. kocka Olah& Johanson all of which have a differently shaped inferior appendage.  Description.  Male.Total length 1.8-2.2 mm, antenna broken, forewings with white band at midlength, body brown in alcohol. Abdominal segment V with pair of setose glands on dorsum. Segment VI with pair of medial sacs on dorsum, lateral finger-like glands which telescope.  Genitalia.Segment VII with pair of setose glands on dorsum, laterally wide dorsally tapering ventrad; in ventral view narrow, with broad incision on posterior margin. Segment IX in lateral view triangular, narrow, and truncate posteriorly, tapering anteriorly into segment VI. Preanal appendage (cercus) short and rounded distally in lateral view; in dorsal view oval in shape. Dorsolateral hook in lateral view thin, slightly downturned apically; in dorsal view narrow over length, preapical spine on outer margin. Segment X thin and shelf-like in lateral view; in dorsal view rectanguloid. Inferior appendage triangular in lateral view, tapering distally to rounded apex; in ventral and dorsal views oval in shape with lateral margins lightly sclerotized. Phallus in dorsal view thin and elongate, pair of apical spines, lowermost spine curving outward, upper spine short and straight; in lateral view, subapical spine curving upward and apical spine, separated and curving downward.   Figure 13.  Metrichia leahaesp. nov., male holotype, genitalia Aleft lateral Bventral Cdorsal Dabdominal tergites V-VII, dorsal Ephallus, dorsal Fphallus apex, left lateral.  Distribution. Panama.  Etymology. This species is named for Leah Keth, who completed many of the illustrations in this paper and in many others in previous manuscripts for the authors. 2017-04-19 2017-04-23 2017-04-19 Malaise trap T.
