Characteristics & Similar species
Like other members of the Heteromeringia czernyi species group, H.  czernyi has two pairs of vibrissae, an additional upcurved posterodorsal bristle on the anepisternum just before the wing base, and a plumose (not pubescent) arista. Heteromeringia czernyi and H. flavipes (the only other species of this species group known from North America), are further characterized by a cloud around the cross-veins, and a small rounded surstylus with an internal process and sometimes scale-like bristles. Heteromeringia czernyi differs from H. flavipes in having almost entirely brown tibiae (only the mid tibia is brown in H. flavipes).

Distribution
Heteromeringia czernyi is a very common neotropical species that probably has the widest distribution of all New World Clusiidae - it extends throughout the tropics from central Mexico to Bolivia and southern Brazil, and has been found in Tierra del Fuego, Argentina. In North America, it is only known from two localities in central and southern Florida.

Biology
Heteromeringia czernyi has been collected in Malaise, flight intercept and pan traps, and like many other Heteromeringia, appears to prefer open areas such as tree falls. It is regularly found near dung and is one of the few Clusiidae to have been collected from carrion.
