Species Guides
1- Paracloeodes minutus(small minnow mayfly)
Paracloeodes is a of small minnow mayflies in the Baetidae, established by Day in 1955. The genus contains at least 23 described distributed across the Americas, with the highest diversity concentrated in the Neotropical region. Nymph- associations have been established for only nine species, indicating significant gaps in life stage knowledge. Recent taxonomic work has focused on describing new species and clarifying previously unknown adult stages, such as for P. carolinae.

Identification
-level identification within Paracloeodes relies on specific morphological characters of nymphs and . Nymphs may be distinguished by features such as shape (deeply distomedial margin in some species), relative length of and paraglossa, maxillary palp proportions, presence and arrangement of setae on foretarsus, and paraproct spine count (e.g., 24–28 marginal spines). Male imagos can be identified by coloration (yellow turbinate portion in P. carolinae), wing venation patterns (stigmatic area with four not reaching subcostal vein in P. carolinae), and subgenital plate (concave margin with pointed spine in P. carolinae).
Habitat
Freshwater aquatic environments; specific microhabitat preferences not documented in available sources.
Distribution
Panamerican distribution spanning North, Central, and South America. Greatest occurs in the Neotropics. Documented from Brazil (including poorly sampled areas), Colombia (Caldas, Tolima departments), and other regions.
Life Cycle
Hemimetabolous development with aquatic nymphal stage and terrestrial stage. Nymph-adult associations have been established for only nine of 23 described , indicating that complete descriptions remain incomplete for most . Adults of P. carolinae have been successfully reared from nymphs in laboratory conditions.

Distinguished from related by specific combinations of mouthpart , tarsal setation, and male genitalia characters as detailed in -level descriptions.
