Pythidae of New Hampshire - Pytho

Pythidae of New Hampshire - Pytho
Nashua, Hillsborough County, New Hampshire, USA
April 28, 2005
Size: all 12 mm
All three species of Pythidae that live in New Hampshire: Pytho niger, Pytho planus, and Pytho seidlitzi.

Pythidae: Pytho planus and niger
Sorry, no Pytho seidlitzi here. The two planus (brown and metallic forms) and two niger are more or less opposite each other. P. seidlitzi has the pronotal margins parallel or nearly so for most of their length.

 
Shame on me!
I assumed. I should have fought back the giddiness of having nailed down the entire family in a couple afternoons of bark stripping.

What does the really rare one look like?

 
Missing species: Pytho stictus or strictus?
Can't remember the correct name now, but it has the lateral pronotal margins roundly angulate at the middle - we don't have it in the collection and apparently is VERY rare here - the northern part of its range. P. seidlitzi has the lateral margins largely parallel or nearly so. P. niger has them evenly rounded, while P. planus has the anterior angles broader than the posterior angles. Only remember this because I was looking at them today. It will be forgotten within a week.

 
How about Prio*gnathus monili*cornis?
That's the fourth species in Pythidae on the UNH checklist. Nearctica site lists a Pytho stric*tus.
