Zagrammosoma ?centrolineatum ex Phyllonorycter platani - Zagrammosoma centrolineatum - Male
Feather River, Sutter County, California, USA
Size: 1.3 mm

Moved from Zagrammosoma.
Thanks for taking a look. This is one of ~100 eulophids I sent to Dr. Hansson in my last shipment, so I'll report back with his assessment sooner or later.

Good to have help of an expert
Much may have changed since the references I mentioned below were published.

For instance, the Figures 7 & 8 listed as "Z. nigrolineatum" in Gordh (1978), now appear listed as Cirrospilus vittatus on this web page from R. Burks UC Riverside web site.

Christer Hansson did in fact ID this as Z. centrolineatum.

Fascinating genus...good finds& work, Charley!
I just bumped into the BG node for this amazing genus, and subsequently found Biodiversity Heritage Library links for the two references below (in case you didn't have access to them):

Gordh, G. 1978. Taxonomic notes on Zagrammosoma, a key to the Nearctic species and descriptions of new species from California (Hymenoptera: Eulophidae). Proceedings of the Entomological Society of Washington. 80: 344-359. (Full text)

LaSalle, J. 1989. Notes on the genus Zagrammosoma (Hymenoptera: Eulophidae) with description of a new species. Proceedings of the Entomological Society of Washington. 91: 230-236. (Full text)

Initially I was excited that I might be able to use the above to ID some of the BG posts. But after a brief attempt to read through the keys and compare with posts, I'm wondering if there may be a number of undescribed species...or if those already described may have too much variation for me to cavalierly use the key without experience studying lots of specimens. (That is, though well-intentioned, my initial zeal for trying to place some of the posts may have been based on hubris! :-)

But, at least for your post here, I'm think it's a fairly good bet that it's Z. centrolineata, like your other post that was confirmed by Christer Hansson:

The wide central dark stripe on both the meso- and metasoma, and the fairly distinct wing infuscation correspond well with the figures in Gordh (1978) and with your post in the thumbnail above.
