<paragraph pageId="0" pageNumber="22396">Female (Figs 2, 3). Body length 0.395 mm, flattened, limuoid. Flagellomere 1 pointed, with long setae almost as long as flagellomere 1 + apparently 2-articled arista (difficult to discern due to small size of specimen). Palpus large, broad with apical setae. Proboscis greatly reduced. Genal margin with few setae. Frons broad, without differentiated bristle-like setae; eye greatly reduced to few ommatidia. Scutum with short sparse setae dorsally. Scutellum with 2 pairs of large setae. Forelegs, especially forecoxa, greatly enlarged; forefemur with three anteroventral setae. Mid- and hind legs greatly reduced, possibly vestigial. Abdomen extremely small, covered by scutellum. Oviscape pointed.</paragraph>

<paragraph pageId="0" pageNumber="22396">Unknown, but almost certainly a parasitoid. The torn wing membrane is reminiscent of other phorid flies that shed their wings when entering a social insect colony. It seems likely that the greatly enlarged forelegs are used to clutch a host, upon which the small, rounded body would appear similar to that of many phoretic mites.</paragraph>

It is common for researchers to change the alcohol in Malaise trap samples, pouring off the old liquid, stained yellow with body fluids of the many preserved insects. Also, we commonly drain the alcohol out of samples for safer or at least more legal transport of these chemicals. Fortunately, the samples including the

sp. n. were examined immediately after being collected and were thus not so treated. The tiny phorid flies described herein are easily lost when waste alcohol is drained off, such that any alcohol that is being disposed should be first examined carefully under a microscope. Furthermore, I suggest purposely

Malaise trap samples in fresh alcohol to clean tiny insects off of the larger ones and search for further microfauna.
