There are 4 current projects at the University of Delaware that delphacid specimens are needed on loan:

(This list as PDF:  Delphacid specimens needed Bartlett 2010 UDEL)

1) A revision of the "Delphacodes puella" clade (Katie Weglarz' Master's project)

This project is a morphological taxonomic revision of Delphacodes species that are, or may be, related to D. puella (see picture below).  This will include all members of the genus Chionomus.   Some of the species in this group are quite common, and we have plenty of specimens and records to work with.  Others, such as those species below, appear less often in collections, and we would like to find additional specimens and obtain new records.  At present, we are not sure exactly what species belong with this group, so we are going to look at a few things that may not belong.  Several of these species are known only from the type specimen.

Delphacodes ardentis Beamer, 1948 (reported USA: FL)

Delphacodes banosensis Muir, 1926 (Banos, Ecuador)

Delphacodes bellicosa Muir and Giffard, 1924 (USA: CA)

Delphacodes concava Beamer, 1948 (USA: FL, GA)

Delphacodes dentis Beamer, 1948 (USA: TX and Canada: NWT!)

Delphacodes gluciophila Muir, 1926 (Banos, Ecuador)

Delphacodes mesada Caldwell, 1951  (Puerto Rico)

Delphacodes pacifica (Crawford, 1914) (USA: AZ, CA, IL, MO, MS; Mexico)

Delphacodes penepuella Beamer, 1948 (USA: FL, NY)

Delphacodes quadridentis Beamer, 1948 (USA: FL, MS)

Delphacodes quadrispinosa Muir and Giffard, 1924 (USA: FL, Cuba, Nicaragua)

Delphacodes sagae Beamer, 1946  (US: IL, MO, NC, NY; Canada: Ont.)

Delphacodes saxicola Muir, 1926 (Brazil, Rio de Janeiro)

Delphacodes securigera Muir, 1926 (Brazil, "Rezende" = Resende?)

Delphacodes silvae Beamer, 1946 (USA: TX)

Delphacodes tenae Muir, 1926 (Tena, Ecuador)

Nothodelphax venusta (Beamer, 1948) (USA: TX) (was in Delphacodes)

Syndelphax dissipata (Muir, 1926) (reported Brazil, Ecuador) (was in Delphacodes)

If you are a insect collection manager and are willing to look for target taxa in your undetermined for specimens that might be in this group, they all look something like Delphacodes puella, below:

2) A revision of the "Delphacodes andromeda" clade (Ashley Kennedy's Master's project)

This project is a morphological taxonomic revision of Delphacodes species that are, or may be, related to D. andromeda (see picture below).  This includes Caenodelphax as defined by Hamilton (2002).   Caenodelphax teapae is quite common, and we would only be interested in locality records for this species.

Delphacodes shermani (Metcalf, 1923)   (USA: KS, NC)

Delphacodes xerosa Caldwell & Martorell, 1951 (Puerto Rico)

3) Species needed to photograph:

This is a working list of species of which specimens are needed to photograph for the interactive key (sometimes "better" - more photogenic - specimens are needed than those currently available).  Most of these species are not from North America. Males and female, short and long-winged forms are all desired.  Later, there will be a much longer list presented of North American species that I still need.

Of course, I'd be happy to accept good photographs instead.

4) Taxa needed for molecular work (Palearctic wishlist)

These taxa are wanted to improve taxonomic sampling in an ongoing project exploring the phylogenetics of the Delphacidae (in collaboration with Jason Cryan and Julie Urban, NYSM).  This project combines molecular and morphological data, so ideally I could use specimens both for DNA (preserved in alcohol - ideally 95-100% ETOH), and for morphological work (which can be dry or in alcohol).  Although a single specimen (positively identified and well-preserved) will serve for DNA, I have been targeting 3 specimens (males), with any in excess of this used for morphological coding (when needed).  For this project, our prime concern is to have as many delphacid genera represented in the dataset as possible, with a secondary concern of having multiple species within each genus.  While we need taxa from all over the world, the following list is directed toward taxa of the western Palearctic, and was assembled to provide some guidance to colleagues we spoke with at the 13th International Auchenorrhyncha Congress held at Vaison-la-Romaine, France (28 June - 2 July 2010).

Of course, I'd be happy to accept unsorted delphacids from anywhere for molecular work.
