Lorelopsis
Champion, 1896: 15. Type species:
Lorelopsis pilosa
Champion, 1896.
Note.
Champion (1896)
described this genus for a single species,
Lorelopsis pilosa
, from St. Vincent in the Lesser Antilles, comparing it to
Lorelus
. He mentioned the lobe beneath the fourth tarsomere; pronotum narrower than elytra; erect, fine dorsal pubescence; and closed mesocoxal cavities as distinguishing generic characters. The only other species ever placed in
Lorelopsis
was when
Wolcott (1936
,
1951
; see also
Blackwelder 1945
) mentioned an undescribed species from Yauco, Puerto Rico, determined by Chapin as belonging to this genus.
Doyen (1993)
described
Lorelus wolcotti
Doyen, 1993 and listed
Wolcott's
citation as a synonym but did not mention having actually seen the specimens cited by Wolcott.
Doyen (1993)
also stated that "
Lorelopsis
is probably not distinct from
Lorelus
."
Bouchard et al. (2021)
record the two genera as synonyms, listing
Doyen (1993)
as a first synonymy ignoring the provisional nature of the statement.
We reestablish
Lorelopsis
as a valid genus in
Prateini
based upon several characters mentioned in the key and discussion below. Further, we move several species described in
Lorelus
by
Champion (1913)
,
Doyen (1993)
, and
Doyen and Poinar (1994)
to
Lorelopsis
. The new concept of this genus includes the species given in the checklist below, though a number of undescribed species are also known from the West Indies. Note that
Champion (1896
: 15) considered this genus to be masculine with his single described species ending in -
us
and this was followed by all subsequent workers through
Bousquet et al. (2018)
. However, following ICZN Article 30.1.2,
Bouchard et al. (2021)
appropriately treated this genus as feminine and the species epithets are emended accordingly here.

Besides having the characters of
Prateini
,
Lorelopsis
species are small, elongate, parallel-sided, and covered in fine, silky, erect to suberect setae. The pronotum is slightly to distinctly narrower than the base of the elytra and microspiculate on the lateral margin, each spicule with an associated projecting seta forming a fringing row of projecting setae. A distinct and newly observed character is a long, stout projecting seta on the dorsum of the head close to the hind edge of the eye. This seta is clearly visible in species with relatively sparse and short setae on the head (Fig.
19
) but becomes less distinct when more dense and longer setae are present, blending with others (Fig.
20
). Since not all species assigned here have been examined (specifically several of the Champion species from the mainland), and since this character has not previously been mentioned, it is possible that it does not occur in all the mainland species, but it is there in the species we have seen. Some, but not all, species have the fourth tarsomere lobed beneath for a variable length. Champion used this as a primary character when he described the genus, but it has proved to be a species-level character.
