Citation: Bousquet Y, Bouchard P (2014) Review of the species of Paratenetus Spinola inhabiting America, north of Mexico (Coleoptera, Tenebrionidae). In: Bouchard P, Smith AD (Eds) Proceedings of the Third International Tenebrionoidea Symposium, Arizona, USA, 2013. ZooKeys 415: 23–51. doi: 10.3897/zookeys.415.6524
The North American (north of Mexico) species of the tenebrionid genus Paratenetus Spinola are reviewed and a key is presented for their identification. Five species are recognized, P. gibbipennis Motschulsky, P. fuscus LeConte, P. punctatus Spinola and two sp. n., P. exutus [type locality: Tabusintac, Nova Scotia] and P. texanus [type locality: Port Isabel, Cameron County, Texas]. Two syn. n. are proposed: P. cribratus Motschulsky, 1868 with P. gibbipennis Motschulsky, 1868 and P. crinitus Fall, 1907 with P. fuscus LeConte, 1850. A lectotype is selected for Paratenetus punctatus Spinola. A type species is designated for Storthephora Mäklin, 1875 (Storthephora denticollis Mäklin, 1875).

We did not investigate the taxonomic position of the genus Paratenetus but we accept, following
The biology of members of Paratenetus is poorly known. Many of the specimens seen in this study were collected in leaf litter in forested areas or in nests of the tent caterpillar genus Malacosoma (Lepidoptera: Lasiocampidae). All three winged species have been collected at black light.
There are two types of setae on the elytra of Paratenetus: erect and slanting. The slanting setae are characterized as subdepressed when the angle between the base of the seta and the elytra is between 10 and 40°, semierect when the angle is between 40 and 60°, and suberect when the angle is between 60 and 80°.
1 | Metaventrite short, length along midline subequal to or shorter than length of abdominal ventrite 2 along midline | 2 |
– | Metaventrite longer, length along midline longer than length of abdominal ventrite 2 along midline | 3 |
2 | Elytra with very few, short erect setae | Paratenetus gibbipennis Motschulsky |
– | Elytra with numerous, long erect setae | Paratenetus fuscus LeConte |
3 | Antennomere 8 transverse. Metaventrite quite distinctly darker than first two abdominal ventrites in the vast majority of specimens, not or only slightly darker in a few specimens. Protibia of male without calcar | Paratenetus exutus Bousquet & Bouchard |
– | Antennomere 8 subquadrate or slightly elongate. Metaventrite not darker than first two abdominal ventrites in the vast majority of specimens, slightly darker in a few specimens. Protibia of male with calcar | 4 |
4 | Pronotum with maximum width anterior of midlength (Fig. 3); punctures narrowly spaced, in part subcontiguous over lateral half [widely distributed in eastern North America] | Paratenetus punctatus Spinola |
– | Pronotum with maximum width at midlength (Fig. 4); punctures moderately dense, not subcontiguous even over lateral half [known only from Texas, Louisiana and Florida in North America] | Paratenetus texanus Bousquet & Bouchard |
http://species-id.net/wiki/Paratenetus_gibbipennis
Figs 5, 10Motschulsky’s collection at ZMMU contains a single specimen, a female, under the name Paratenetus gibbipennis. It bears the following labels: “[green round disc] / [small brick red square label] / type [handwritten] / Paratenetus gibbipennis Motch Am. b. Mobile [handwritten on a rectangular green label].” The specimen is intact although many of the setae on the pronotum and elytra are gone. The provenance of the specimen is doubtful. In the key to the Paratenetus in his collection,
Motschulsky’s collection contains a single specimen, a male, under the name Paratenetus cribratus. It bears the following labels: “[green round disc] / Atlanta [handwritten] / type [handwritten] / Paratenetus cribratus Motch Am. bor. Atlanta [handwritten on a rectangular green label].” The specimen is missing the left antennomeres 3–11 and the posterior legs.
This species and Paratenetus fuscus differ from the other three species treated by having the metaventrite very short. Paratenetus gibbipennis differs from Paratenetus fuscus by having few short erect setae on the elytra.
Body dorsally reddish yellow to dark reddish brown, legs paler, yellow to reddish yellow; antennal club not darkened in most specimens; metaventrite not darker than first two abdominal ventrites. Antennomere 8 subquadrate or very slightly transverse. Pronotum with maximum width near midlength or slightly anterior to midlength; punctures moderately dense, not subcontiguous even over lateral half. Elytra very convex; slanting setae subdepressed, erect setae very few, short. Metaventrite short, length along midline clearly shorter than length of abdominal ventrite 2 along midline. Male protibia with calcar near middle along ventral surface; male mesotibia with short, in some specimens very short, more or less perpendicular preapical protuberance. Parameres with sides more or less parallel towards apex, apex not particularly acute (Fig. 5).
Length: 2.5–3.2 mm.

http://species-id.net/wiki/Paratenetus_punctatus
Figs 3, 8, 12Most of Say’s entomological collection has been destroyed and we are unaware that a syntype of his Latridius pubescens survived.
Many specimens of Paratenetus punctatus can be separated from the other North American species of Paratenetus by their large size (3 mm or more). The vast majority of specimens of the other species are less than 3 mm long. Otherwise, the species can be separated from Paratenetus exutus in having the antennomere 8 subquadrate, the pronotum wider clearly anterior to the midlength, the punctation on the pronotum coarser, the slanting setae on the elytra slightly longer and more erect and the protibia of the male with a calcar along ventral surface. From Paratenetus texanus, this species is best separated in having the pronotum widest anterior to the midlength and the punctures on the pronotum coarser and denser, in part subcontiguous along the lateral half.
Body dorsally uniformly pale to dark reddish brown in most specimens, with the pronotum and head slightly darker than elytra and legs in some specimens; antennal club darker than antennomeres 1–8; metaventrite not darker than first two abdominal ventrites in the vast majority of specimens, slightly darker in a few specimens. Antennomere 8 subquadrate. Pronotum with maximum width anterior of midlength (Fig. 3); punctures narrowly spaced, in part subcontiguous over lateral half. Elytra less convex than for Paratenetus gibbipennis and Paratenetus fuscus; slanting setae semierect in the vast majority of specimens, suberect in some specimens, erect setae few. Metaventrite long, length along midline longer than length of abdominal ventrite 2 along midline. Male protibia with calcar near middle along ventral surface; male mesotibia with very short, preapical spine, oriented perpendicularly or obliquely to long axis of tibia. Parameres with sides more or less parallel to very slightly convergent towards apex; apex more or less rounded (Fig. 8).
Length: 3.0–4.0 mm.
This species ranges from New Brunswick to southeastern Manitoba, south to eastern Texas, southern Mississippi, and southeastern Florida (Fig. 12).

This species varies in regard to the punctation and setae. The punctation on the pronotum is coarse and in most specimens free on the disc and very close, in part subcontiguous over the sides; in some specimens the punctation is denser, being subcontiguous on the disc and contiguous all over the lateral sides. The slanting setae on the elytra are usually semierect but in some specimens they are less inclined and the erect setae are difficult to distinguish. The erect setae are usually short and moderately numerous but in some specimens, they can be relatively long or much more numerous; in such case the species can be confused with Paratenetus fuscus but is easily separated by the coarse, irregular punctation on the pronotum and by the longer metaventrite.
Females are more common in collections than males. Of 220 randomly selected specimens, 169 (77%) were females and 51 (23%) were males.
Specimens were collected in March (n=6), April (n=89), May (n=296), June (n=384), July (n=152), August (n=67), September (n=40), October (n=9), November (n=5), and December (n=2).

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.
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.
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.

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.

The specific name derives from the name of the state of Texas where the species has been commonly collected.
Members of this species can be distinguished from those of Paratenetus punctatus and Paratenetus exutus in having the punctures on the pronotum sparser, not subcontigous even on the lateral half. They can also be distinguished from most adults of Paratenetus punctatus by their smaller size and from most adults of Paratenetus exutus by the subquadrate antennomere 8 and metaventrite of same color as the first two abdominal ventrites.
Body dorsally yellow to pale reddish brown, with the pronotum and head usually slightly darker than elytra and legs; antennal club slightly darker than antennomeres 1–8 in many specimens, often reddish brown to partially piceous, yellowish and as pale as legs in some specimens; metaventrite not darker than first two abdominal ventrites. Antennomere 8 subquadrate. Pronotum with maximum width at midlength (Fig. 4); punctures moderately dense, not subcontiguous even over lateral half. Elytra less convex than Paratenetus gibbipennis and Paratenetus fuscus; slanting setae subdepressed, erect setae short. Metaventrite long, length along midline longer than length of abdominal ventrite 2 along midline. Male protibia with calcar near middle along ventral surface; male mesotibia with short, preapical spine, wide at base and oriented perpendicularly to long axis of tibia. Parameres with sides distinctly convergent towards apex; apex markedly acute (Fig. 9).
Length: 2.7–3.3 mm.
This species is known from southeastern Florida, central Louisiana, and central and eastern Texas (Fig. 14). We have also seen specimens from the states of Chiapas, Nayarit and Tamaulipas in Mexico.

The two specimens from Miami in Florida externally agree perfectly with those from Texas. One is a male and its genitalia are identical to those of specimens from Texas.
Males are more common in collections than females. Of 106 randomly selected specimens, 42 (40%) were females and 64 (60%) were males.
Specimens were collected in January (n=1), February (n=1), March (n=65), April (n=39), May (n=89), June (n=30), July (n=53), August (n=21), September (n=36), October (n=108), November (n=2), and December (n=6).
Labels on specimens read “at black light in Prosopis and Celtis forest, sandy soil” (6 specimens); “on Celtis” (1); “ex dry okra pod” (1); “cotton” (1); “collected on Celtis” (2); “fallen fruit Yucca treculeana” (1); “on flower Yucca treculeana” (2); “on Acacia Berlandieri Benth.” (1).
This new species occurs in Mexico and nine species have been reported from that country. We have examined the type material of the six species described by Champion and housed in BMNH, i.e., Paratenetus constrictus, Paratenetus corticarioides, Paratenetus nigricornis, Paratenetus punctulatus, Paratenetus tibialis, and Paratenetus villosus, and none of them are conspecific with those of Paratenetus texanus. The three species not seen are Paratenetus tropicalis Motschulsky, Paratenetus koltzei Pic, and Paratenetus mexicanus Pic.
We would like to thank Matthew L. Gimmel for sharing independently-generated information on Nearctic Paratenetus. Thanks are due also to Go Sato for the habitus drawing, to Anthony Davies and Henri Goulet for the photographs, and to Darren A. Pollock and Matthew L. Gimmel for their constructive suggestions on the manuscript. We are grateful to the curators of the collections studied for access to the specimens under their care.
