Etymology

The specific name comes from the Latin participle exutus, -a, -um (deprived of) and alludes to the fact that the protibia of the male lacks the spinelike projection (calcar) found in the other American (north of Mexico) species.

Diagnosis

This species is best separated from Paratenetus punctatus and Paratenetus texanus in having the antennomere 8 transverse. The males are also easily recognized among the species treated here in having no calcar on the protibia and a relatively long apical spine, oriented more or less parallel to long axis of tibia, on the mesotibia.

Description

Body dorsally pale reddish brown in most specimens, with the pronotum and head usually slightly darker than elytra and legs; antennal club darker than antennomeres 1–8, particularly in males; metaventrite quite distinctly darker than first two abdominal ventrites in the vast majority of specimens, not or only slightly darker in a few specimens. Antennomere 8 transverse. Pronotum with maximum width at or very slightly anterior of midlength (Fig. 2); punctures narrowly spaced, in part subcontiguous over lateral half. Elytra less convex than for Paratenetus gibbipennis and Paratenetus fuscus; slanting setae subdepressed, erect setae few. Metaventrite long, length along midline longer than length of abdominal ventrite 2 along midline. Male protibia without calcar near middle along ventral surface; male mesotibia with relatively long, apical spine, oriented more or less parallel to long axis of tibia. Parameres with sides convergent towards apex; apex more or less truncate (Fig. 7).
Length: 2.5–3.0 mm.

Distribution

This species ranges from Cape Breton Island to northwestern Alberta, south to east-central Texas, southern Alabama, and southern Florida (Fig. 13).

Remarks

While almost all specimens from Canada and northern United States had the metaventrite distinctly darker than the first two abdominal ventrites, this is not the case with the specimens from the southern states. There is also variation in the width of the antennomere 8. Most specimens have that antennomere distinctly transverse, some specimens from the southern states (particularly Louisiana) have the antennomere 8 only slightly transverse.
Females are more common in collections than males. Of 105 randomly selected specimens, 76 (72%) were females and 29 (28%) were males.
Specimens were collected in March (n=9), April (n=38), May (n=84), June (n=58), July (n=79), August (n=40), September (n=22), October (n=5), November (n=3), and December (n=2).
Labels on specimens read “at black light near mixed forest, farmed fields and tidal creek” (4 specimens); “at black light at edge of mixed forest and open turf on hill” (1); “in moldy leaf clusters on cut branches of Acer rubrum” (3); “beaten ex spruce” (35); “beaten ex fir” (10); “on Bumelia lanuginosa” (1); “ex. spruce” (1); “ex. canopy trap” (15); “ex. FIT, near upper meadow” (1); “ex. FIT, near lower meadow” (3); “ex. canopy malaise, near lower meadow” (9); “ex. canopy FIT, near lower meadow” (3); “malaise trap” (6).
Most specimens of this species in collections are identified under the name “Paratenetus inermis Bsq. and Bouch.” since it was the intended name. Unfortunately, we realized that the name was already used by Champion only after the specimens were returned to their respective collections.
