Name
Paratenetus punctatus Spinola, 1844 – Wikispecies link – ZooBank link – Pensoft Profile
- Latridius pubescens Say, 1826: 265 [nomen dubium]. Type locality: United States (inferred from title of the paper).
- Paratenetus punctatus Spinola, 1844: 118. Type locality: «Etats-unis de l’Amérique septentrionale» (original citation). Synonymy established by LeConte (1859[1]: 325).
Type material
Most of Say’s entomological collection has been destroyed and we are unaware that a syntype of his Latridius pubescens survived. LeConte (1859[1]: 325) based his interpretation of Say’s species on the original description. For nomenclatural stability, we believe it is best to consider Latridius pubescens Say as a nomen dubium and retain the long accepted name Paratenetus punctatus Spinola for this species.
Spinola (1844[2]: 119) indicated that he had three specimens of Paratenetus punctatus which came from Dejean’s collection. These specimens were received for study from the Museo Regionale di Scienze Naturali in Turin (MRSN). The first specimen, probably a female, is labeled “Paratenetus punctatus Ekis 1974 [handwritten]”; the second, a male “Paralectotype Paratenetus punctatus Spinola Ekis 74 [handwritten]”; and the third, a female “Lectotype Paratenetus punctatus (Spinola) Ekis 74 [handwritten]”. The first two specimens correspond neither to our concept of Paratenetus punctatus nor to any other North American species we have seen. The specimens are in poor condition, with almost all the setae gone, but they appear to be conspecific. Although Spinola indicated that all three of his specimens came from the United States and were provided by “Mr. [John Eatton] LeConte,” these two specimens may have originated from Mexico, Central America or South America. The third specimen, a small individual (3.2 mm), fits our concept of Paratenetus punctatus and is here selected as lectotype. The label “Lectotype Paratenetus punctatus Spinola des. Y. Bousquet 2012” has been attached to the specimen.
Diagnosis
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.
Description
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.
Distribution
This species ranges from New Brunswick to southeastern Manitoba, south to eastern Texas, southern Mississippi, and southeastern Florida (Fig. 12).

Remarks
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).
