. In 2003, we collected the first four female specimens on mushrooms associated with a decaying log near a road. The specimens were found in the galleries they excavated in the mushroom pileus. The absence of males may indicate that the females were ovipositing and/or providing parental care. When disturbed, the females tried to escape and we did not have an opportunity to observe their behavior. We tried to collect more specimens, particularly males, for several days searching additional mushrooms (
and others). We also installed temporal traps baited with local mushrooms, but all our attempts were futile. In 2004, the first author visited the same decaying log where the first specimens had been found and collected three more specimens, one of them a male. Again, extended search for additional specimens on other mushrooms and use of a flight intercept trap produced no results. Thus, the new species has been collected only on mushrooms of the genus
may be a rare species, possibly because the host mushroom species may also be rare.
