M. katae is a rather rare species, virtue of the scarcity of its lowland habitat, as explained in the Check List article.
|Macromia katae, a beautiful Macromia. Note the darkened wing bases.|
|The face is very dark, with small yellow markings on labrum, base of mandibles, and postclypeus.|
|The dorsal spine on S10 is very prominent|
|The epiproct is quite long, extending well beyond the superiors|
|Typical hamule and lobe. What I found striking is that the genital lobe is bicolored.|
