Head capsule dorsally with fine, randomly scattered setigerous punctures (setae not visible or only barely so at 50× magnification) from constriction of neck extended anteriorly toward clypeus. Elytra with striae moderately impressed and punctulate throughout length; intervals slightly convex (few with greater convexity in intervals 1, 3 and 5); abdominal sterna with fine pilose punctures throughout.
Fixed setae. Elytra with 14–15 lateral (umbilical) setae;two setae on each of abdominal sterna III to VI; 4 setae along apical margin of sternum VII (Fig. 3).
Luster. Head capsule and pronotum glossyl elytra moderately glossy.

Hind wings. Macropterous.
Male genitalia. Phallus (Fig. 14A) length 1.70 – 2.42 mm.

Variation

Through the range of Cymindis platicollis platicollis a three-phased cline is observed (Fig. 17, Table 4). Phase 1: northeastern specimens have an average overall body length of 8.83 mm, average phallus length of 1.76 mm (Fig. 15A) and are dorsally glabrous; (~75%) with a single row of ~50–80 (interval 2 with more than 70) punctures in interval 1–7, some (~25%) with one to two rows of punctures in intervals 2, 4 and 6, all others with one row of punctures (except interval 8 with two to four rows). Phase 2: more southern specimens have an average overall body length of 9.22 mm, average phallus length 1.82 mm and have dorsal setation on humeral area of elytra; some specimens with few setae visible on dorsum of head and disc of elytra; (~86 %) with odd intervals bearing one row of scattered setigerous puncture and even intervals bearing two or three rows of scattered setigerous punctures, others (~14%) with interval 2 having two or three rows of setigerous punctures (rarely one row), interval 8 with two or three rows, and all other intervals bearing one row of setigerous punctures. Phase 3: southwestern specimens (extreme south west Oklahoma to mid-western Texas south west to Nuevo Leon) have an average overall body length of 9.92 mm, an average phallus length of 2.08 mm (Fig. 15B) and are dorsally setose, most individuals having one or two rows (mostly two) of moderately deep, randomly spaced, pilose punctures in all intervals, interval 8 with two to three rows. Few with various combinations of above.

Table 4. Geographical variation in the extent of elytral punctation in Cymindis platicollis platicollis (Say), by state (and regions of Texas) and number of individuals examined. Legend: 1, dorsal surface of elytra glabrous, punctation fine; 2, dorsal surface of elytra setose basally, punctation moderately fine; 3, entire dorsal surface of elytra setose, punctation coarse.

Habitat, habits and seasonal occurrence

The known elevational range of Cymindis platicollis platicollis extends from 3 to 1935 m. Specimens were collected under stones, under and on bark of trees and associated mosses in forests of buckeye, beech-magnolia, elm, hackberry, hickory, juniper, mesquite, oak, oak-pine, and tamarack. It has been collected from shrub species Leucaena pulver (Schltdl.), from bromeliads associated with oak and also from the nest of woodrats, Neotoma micropus Baird. Adults are crepuscular, and most commonly collected from late February through July.
I witnessed several pairs in copula over a three-week period of collecting in Georgia and Florida from late February to mid-March of 2008. Of these mated pairs I brought 9 females and 10 males back to the University of Alberta to attempt rearing larvae. I kept them all in a single plastic container with substrate from under the trees they were captured on. A wet ball of tissue provided moisture, and several 3rd to 5th instar larvae of cabbage looper moth species Trichoplusia ni (Hübner) were introduced each week for food. All individuals (with the exception of one female) survived for the first three months in captivity. By mid-June (three months after capture) males started to die, and within the next two weeks all had expired. All of the remaining eight females lived at least until mid-September (6 months after capture) with the last individual dying in early November (7.5 months after capture). Males lived an average of 82 days after capture and females lived more than twice as long with an average lifespan of 166.5 days after capture.
All beetles were removed from the container every week and the substrate was searched for eggs and larvae. No evidence of oviposition was found. Other attempts to rear larvae from mated Pinacodera adults (Mahar, 1978) were also unsuccessful. Many lebiines are known to have unusual ovipositional habits or needs; that may also be the case in Pinacodera and a reason why rearing is problematic.
Collecting methods include asafetida and molasses traps, sugar baits painted on tree trunks, beating and sweeping vegetation, at light and u.v. light, Lindgren funnel traps, Berlese traps, Malaise traps, flight intercept traps (FIT’s), pitfall traps, hand collecting, and sticky traps.

Geographical distribution

The range of this subspecies (Fig. 17) extends in eastern Canada from southern Quebec west to southern Ontario; in the eastern United States from Maine south to mid-Georgia west to eastern Colorado and Nebraska south to southern Texas. In Mexico it is known from Nuevo Leon in the northern portion of the Sierra Madre Oriental.

Evolutionary affinities

This subspecies is, by definition the closest relative of Cymindis platicollis atripennis.

Chorological affinities

Cymindis platicollis platicollis is sympatric in portions of its range with Cymindis limbata, Cymindis complanata, Cymindis punctigera punctigera, and Cymindis chevrolati. It is allopatric with Cymindis platicollis atripennis, Cymindis rufostigma, and all other taxa in the limbata species group.

Material examined

I have examined 897 specimens of Cymindis platicollis platicollis: 24 males and 17 females were dissected. For details see University of Alberta Strickland Virtual Entomology Museum Database (University of Alberta 2009[23]).
