Name
Paratenetus gibbipennis Motschulsky, 1868 – Wikispecies link – ZooBank link – Pensoft Profile
- Paratenetus gibbipennis Motschulsky, 1868: 193. Type locality: «Atlanta, Géorgie américaine» (original citation).
- Paratenetus cribratus Motschulsky, 1868: 193. Type locality: «Géorgie américaine» (original citation). syn. n.
Type material
Motschulsky’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 (1868[1]: 193) mentioned that the species was collected in Atlanta but Mobile is listed on one of the type labels. Motschulsky collected in both localities during his 10-month trip to America in 1853–54.
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.
Note about synonymy
Motschulsky (1868)[1] separated Paratenetus gibbipennis and Paratenetus cribratus on the account that the first species has the lateral denticles of the pronotum very short while the second species has strong denticles. From an examination of the types, we cannot sustain Motschulsky’s affirmation; the denticles are basically of the same size on both specimens.
Diagnosis
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.
Description
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.
Distribution
This species ranges from southern Maine to southwestern Manitoba, south to central Texas, southwestern Alabama, and central South Carolina (Fig. 10).

Remarks
Females are much more abundant in collections than males. Of 183 specimens randomly selected, 8 were males (4.4%) and 175 were females (95.6%). The males came from Georgia (n=1), Alabama (n=6), and Missouri (n=1). No males were found among the 160+ randomly selected specimens from Canada and the northern states.
Specimens were collected in January (n=1), February (n=1), March (n=89), April (n=64), May (n=8), June (n=61), July (n=20), August (n=95), September (n=31), October (n=38), November (n=6) and December (n=2).
Labels on specimens read “in leaf litter” (6 specimens); “in leaf litter of black birch and shrubs around and on areas of exposed rock” (71); “forest litter sifting” (2); “forest litter” (3); “moist forest berlese” (1).
