Are they from the Neotropics? Very recent arrival or so rare that they were never noticed before?

Synonym desc. from Tamaulipas, Mexico
Beatriz, Atrypanius irrorellus is a very recent arrival from Mexico. A species that's now a synonym was actually described from Tamaulipas, Mex in 1918. Cameron County of southmost Texas is one of the most intensively entomologically surveyed regions in the state. The boll weevil migrating north reached Brownsville ca. 1900 induced the state legislature to form what is now Texas A&M Dept of Entomology to try address the pest. Early 20th century collectors, such as Charles Schaeffer, knew the palm grove as "San Tomas" (More info).
A short series of Atrypanius irrorellus was collected earlier this year within sight of the Rio Grande. A second short series was collected this month. If only one had been collected, then it's possible that it might have been an over looked member of our fauna, but collecting ten or so in a matter of months suggests it's a recent addition.
