Discovery Trail Park (Lang Crossing) on NF-18, Bowman Lake rd., 39.3090, -120.6657. Ele = 1360 m., Nevada County, California, USA
June 17, 2015
Size: 3.5 mm
Black Light and Mercury Vapor lights.
Specimen was covered with mud so soaked for 24 hrs in Simple Green and used vibrator on vial to shake off mud.
Characteristics that make me think this is G. californica (which isn't in BG to compare with), that relate to pictures, using Gordon's keys (1)
. Other possibilities depending on interpretation of characters are G. mendica & M. paramendica. I have no other specimens to compare this with. With correct sp. identified some pics can be removed that aren't important.
- Metasternal groove picture
is oriented head to left. Mid leg removed (by accident), attachment hole at bottom. Groove is deep posteriorly, shallow towards center of body anteriorly with the arrow pointing to the deep side.
- Pronotal frontal fovea
I considered to be deeply impressed.
- Elytral striae strongly, nearly continuously carinate.
- Posterolateral emargination of mesotibia
with 3 widely spaced spines and another next the 4th (as opposed to the key which says 3 or 4 short, widely spaced spines).
- Mesotibial apex weakly projecting laterally, projection rounded.
- Tubercles on head
- Apiical posterosuperior metatrochanteral margin
with 2 small teeth.
- Metatasternal sculpture
irregular, forming reticulate pattern, but meeting hind coxa only near the center.
