Didion punctatum? - Didion punctatum

Didion punctatum? - Didion punctatum
Loomis, near Whiskey Bar Rd., elevation 213 m (700’), 38.81986, -121.11735, Placer County, California, USA
August 23, 2019
Size: 1.5 mm
Taken in a Lindgren Funnel set out from Aug 16 to Aug 23, 2019.

Posted to add Didion genus to BG range map for CA.
Didion punctatum agrees as much as I can see with the species key in Gordon (1).

This location is within the range map listed by Gordon (Map).

Characters possibly important from Arnett (2) and Gordon (1):
Head
-- Maxillary palpus shape, parallel sided.
-- Antennal club shape not spindle shape.
-- Eye canthus very small if any.
Thorax
-- View = prosternal intercoxal process in center of picture. Intercoxal process extending back between the mid coxae. Prosternum with only abbreviated ridges near coxal cavities, not extending forward. This picture shows no carina on the anterior part of the prosternum.
-- Lateral margin of pronotum nearly straight, margins converge sharply near the head.
Body
-- Dorsal surfaces pubescent.
-- Punctures on elytron large, deep, distinct (see dorsal and side view).
-- Postcoxal line complete and curving forward.
-- Abdomen with 5 ventrites I think (according to Arnett's key should have 6 but other characters push it past this couplet).
