“…Six genera native to the neotropics were not found, but are known to occur throughout Costa Rica: Amiota and Phortica ( Sinophthalmus ), the two genera of which are closely related (there are several subgenera of Phortica ). There are approximately 50 Nearctic species of Amiota (Jones and Grimaldi, 2022); neotropical species have hardly been studied. There are only two described species of P. ( Sinophthalmus ) but perhaps 10 undescribed species, all from Central America.…”

“…Flies in both groups are easily collected since they (especially males) are attracted to perspiration and eyes of various mammals, including humans. They prefer montane forest, where they breed in decaying trees like Stegana (e.g., Jones and Grimaldi, 2022). Likewise absent were Palmomyia Grimaldi and Apachrochaeta Duda, two small, closely related genera, the former of which is attracted to (and probably breeding in) palm flowers, habits of the latter genus unknown.…”

“…8, 9. Miller et al, 2017Jones and Grimaldi, 2022 Waorani species diversity is probably a significant underestimate, since only one sampling method was used, albeit one that allowed roaming the entire sampling area. Sampling was also not continuous like at Zurquí, done neither throughout the year nor at night when some species fly.…”

The highest single-site species diversity known thus far in the world for Drosophilidae is in Costa Rica, based on findings in this report. A total of 352 species of Drosophilidae (Diptera) were found in a cloud forest (1580 m) in Zurquí de Moravia, San José Province (hereafter "Zurquí"), based on 2908 specimens collected continuously for one year, using eight trapping and collecting methods. There are currently 305 described species from Costa Rica. Zurquí is at the edge of a large, protected area and was the site of an All-Diptera inventory project. For this study, drosophilid specimens were identified to genus/subgenus, sorted to morphospecies, and their abundances plotted by collection method: Malaise traps, flight intercept traps, baited traps, light and yellow pan traps, emergence traps, and hand collecting with nets. The standard method used by drosophilists, bait trapping, captured a small fraction of species. Malaise traps captured 87% of all species, and 41% of the 352 species were captured only this way. Emergence traps captured a surprising diversity (47 species) of Diathoneura and Drosophila, establishing that leaf litter/humus is an important breeding site for some taxa. Combining all collection methods, 11 species were abundant, as defined by 50 or more specimens, and comprised 35% of all specimens in the study; two-thirds (66%) of all species were rare, as defined by five or fewer specimens. Comparisons are made to other well-collected sites and regions around the world. Lowland to mid-montane forests on the eastern slopes of the Andes may be the most diverse area for Drosophilidae, a family that is exemplary for studying the ecology and evolution of tropical diversity.
