Holzenthal This list is meant to supplement and update the bibliography cited in the Catalog of the Neotropical Cad- disflies (Flint et al 1999) and the literature updates in issues 1 and 2 of Nectopsyche. The former work contained a list of literature through the end of 1998, but included some works published in early 1999. Users should con- sult the Catalog for a comprehensive list of Neotropical taxa and associated bibliographic citations . Select the link “Literature Cited” to download copy of the Catalog’s bibliography in PDF format. The list presented below was obtained through Zoological Record’s searchable on-line database available through the University of Minnesota Libraries. A search was performed using the keyword “Trichoptera” for the years 2004 through May, 2006. Only those records pertaining to the taxonomy, distribution, or biology of Neotropical Trichoptera are included. Papers of a general benthological or ecological nature, not directly ad- dressing Trichoptera were excluded. Readers of Nectopsyche are encouraged to send me bibliographic citations to include in future issues. Any errors of omission or spelling in the current list are my own; these will be corrected in subsequent newsletters.

Wow! The genitalia looks just like a polycen- tropodid, but it has ocelli. Perhaps this is an interesting case of speciation across lineages through introgression. The result could be the formation of intermediate or introgressed popula- tions which, because of their hybrid origin also had Being an Entomologist increased genetic variance, most relevantly for characters relating to the structures of the head, but quite possibly also by Lourdes Chamorro-Lacayo & Ralph Holzenthal for unobserved characters, such as pheremonal, behavioral or ecolocigal traits. Newly acquired differences developed in these populations may have been sufficient to allow them to become effectively self discriminating and genetically isolating, thus also Oh... wait... Wow!
