KY spider 16 - Dictyna formidolosa - male

KY spider 16 - Dictyna formidolosa - Male
Pulaski County, Kentucky, USA
May 28, 2011
Size: 2 mm
Ex yellow pan trap. Collection date is 27.V.2011 to 29.V.2011

2nd specimen
Follow-up: There was a second specimen, also male, that I found in the batch "KY spiders 8 to 16" that for some reason I hadn't examined. It is now together as a lot of 2 males with this specimen.

Moved from Spiders. Neat, a new species for the guide.

Should you come across these again, I wouldn't mind seeing a couple more just for the sake of comparision.


Dictyna formidolosa --- kmp-10019
This central/eastern species is somewhat similar to the western D. calcarata in that the palpal tibia has an extremely long spur ("carpoblem" according to Kaston, 1948) with two black ctenidia at the apex. The dorsal pattern is actually more or less the reverse of what one sees here: "four pairs of black spots on the posterior half of the dorsum" (Kaston); here the spots merge together to create almost an inverse pattern.

Chamberlin & Gertsch (1958) report that it is common in ground detritus.

Difficult to see much here, b
Difficult to see much here, but certainly looks interesting. Hope you can forward this one, too.

will be mailed beginning of next week :)

spider with white spots
There is hope for this one if we can match up that pattern.
