Peripsocus close to stagnivagus Chapman - Peripsocus - male

Peripsocus close to stagnivagus Chapman - Peripsocus - Male
San Marcos, Hays County, Texas, USA
October 6, 2010
Size: 2.1 mm
This specimen (caught on cedar elm) is very similar to Peripsocus stagnivagus. The phallosome, visible through the abdominal wall is shaped like Fig. 725 (Mockford, 1993). The wing venation and pigmentation are almost identical except that the darker spots along M2 and M3 (Fig. 724) are not evident here. Mockford mentions that "This species is very close to an undescribed species in central Mexico and a second undescribed species in southern Mexico" (p. 215). In addition Mockford told me that males of P. stagnivagus are rare. So, all I can say for sure is that this specimen might be P. stagnivagus. I could send the specimen to him and see what he says.

Moved

Moved tentatively; sounds good enough for me - and thanks again!
Moved from Peripsocus.

 
Genus level may be more appropriate
In addition to the concerns that Diane and Dr. Mockford raise (missing wing spots, rarity of males), the wings seem longer than in the images of P. stagnivagus in the Guide.

 
You are so right..
This one is likely the un-described Peripsocus with the macropterous female. It should be removed from stagnivagus.
