Holotype
male:
9.5 mm
. Deposited at
MNKM
.
Diagnosis:
See diagnosis under description of genus.
Description of
holotype
:
Elongate, narrow species; forebody (
4.25 mm
) 1.2 shorter than abdomen (
5.20 mm
). General colour opaque, shining black, without metallic reflection; centre of elytra paler and somewhat translucent (but not at all vitreous); the following yellow: maxilla (except apical palpomere); narrow rings on base of antennomeres VI-XI; basal third of metafemora; and extreme base of metatibia.
Surface ornamentation:
Above: frons densely punctured, each puncture with short suberect, white hair. Pronotum with scattered erect, long and short hairs, as found on frons (these in male forming indistinct patches of pubescence laterally); paired sulci with simple, smaller punctures. Elytra punctate (each puncture with very short hair), punctures dense, confluent and alveolate on apical third; and basal third moderately clothed with long, erect pubescence. Below: mentum-submentum multicarinate, and densely punctured, the punctures non alveolate, moderately large, and deep. Prosternum multicarinate with dense, moderately large, transverse punctures. Meso- and metasterna with recumbent, grey pubescence (on sides of mesosternum, mesepimeron, base of metasternum, and metepisternum). Abdomen hardly punctate (slightly denser towards sides); pubescence recumbent, very short to short (with scattered suberect hairs towards sides); punctures shallow, transverse, and slightly beveled.

Structure:
Head width with eyes (
1.15 mm
); rostrum moderately narrow (width
0.85 mm
, length
0.30 mm
), much shorter than length of inferior lobes (
0.60 mm
), sides slightly narrowed to apex. Maxillary galea very narrow, twice as long as lacinia, and much longer (
0.80 mm
) than palp (
0.50 mm
). Labrum projecting, rectangular, depressed apically; apical margin almost straight. Clypeus short, prominent transversely, declivous with both labrum and frons, punctate towards centre. Eyes moderately convex; inferior lobes with interocular distance (
0.10 mm
) much narrower than width of one inferior lobe (
0.55 mm
); superior lobe with 6-7 ommatidia, width of lobe (
0.15 mm
) about one-third interocular distance (
0.40 mm
). Antennae reach apex of urosternite
II
; moderately narrow; antennomeres III-VI filiform,
VII
wider at apex,
VIII-XI
uniformly widened,
XI
with short cone at apex. Scape (
0.60 mm
),
III
(
0.90 mm
),
IV
short (
0.60 mm
),
V
(
0.80 mm
),
VI
and
VII
(
0.60 mm
),
VIII
(
0.50 mm
),
IX
and X (
0.45 mm
),
XI
(
0.50 mm
). Prothorax 1.2 longer (
1.50 mm
) than wide (
1.25 mm
), sides converging; width (1.00 mm) of front margin narrower than width (
1.15 mm
) of hind margin (the former with narrow, raised border); apical constriction feeble, basal constriction short but stronger. Pronotum: paired calli not overhanging basal constriction, nor hiding sides of hind angles. Elytral length
4.40 mm
, 3.0 longer than width of humeri; width of elytron measured at beginning of apical third
0.30 mm
; apex of elytron not bordered, sutural angle with minute tooth, lateral angle unarmed and almost square.
Legs:
Front leg relatively short (
3.65 mm
); peduncles short; underside of clave slightly spiculate. Middle leg longer (
4.45 mm
), femora bisinuate; peduncle about two-thirds length of clave; underside of clave spiculate towards apex; tibia gradually widening to apex. Hind leg comparatively long (
8.40 mm
), about twice length of middle leg; peduncle almost straight; clave rather narrow, its apex reaching middle of urosternite
IV
. Pro- and mesotarsi similar, tarsomeres short, I slightly
elongate,
II
trapezoidal,
III
wide and strongly bifid. Metatarsomere I long (
1.30 mm
), 1.4 longer than
II
+
III
(
0.90 mm
);
II
and
III
as mesotarsus, except
II
slightly more elongate.
Variation:
Colour variation absent, but less opaque panels on elytra may be much reduced (in
holotype
extend from well behind humeri to apical fifth), or slightly more extensive. Mouthparts may be browner; apical antennomeres may be chestnut with cinnamon coloured pubescence; apical half of elytra may be bronzy. Suture of elytra may lack border for apical quarter. Prothorax may be more cylindrical, the sides less convergent (but still 1.2 longer than wide); prosternal process may be more arced, and apex sub-trapezoidal (with broadly rounded apical angles). Width of elytron measured at beginning of apical third varies from
0.30 mm
(as in
holotype
) to
0.45 mm
; and apex may be slightly lobed.
Description of female (
Fig. 6B
):
Example size
10.30 mm
; elongate, antennae and legs much as male, but body more robust; forebody (
4.50 mm
) slightly shorter than abdomen (
4.75 mm
). General colour as male (including colour of pubescence), or as follows: opaque, shining black, without metallic reflection; disc of elytra (from base to apical third) distinctly paler and less opaque; the following yellow: base of antennomeres IV-XI yellow (
IV-VII
very narrowly yellow,
VIII-XI
more obviously), pronotum (except paired calli), prosternum in
one female
entirely black, in other yellow, basal half of metafemora, extreme base of mesofemur, and all tibiae. The puncturation also similar to male except: frons less densely punctured; on pronotum more uniform, lacking the small- er, simple punctures present in the male; and elytra, also uniformly, but more densely punctured, and less rugose anteriorly. Mentum-submentum uniformly carinate, with sparse, deep punctures.
Structure:
The female shows the following structural differences from the male: rostrum 2.3 wider (
0.90 mm
) than long (
0.40 mm
), shorter than length of inferior lobes (
0.55 mm
); clypeus not declivous with both labrum and frons; eyes less convex; inferior lobes with interocular distance (
0.45 mm
) equal to width of one lobe (
two females
from the
Department
of
Chuquisaca
have a narrower interocular (
0.35-0.40 mm
); interocular flat and planar with eyes, with uniform, dense, small, round punctures; frontal suture just traceable from well behind superior lobes, where it is prominent, to middle of frons, where it is superficial; superior lobe of eye with 8-9 ommatidia; antennal structure similar to that of male, with the following differences: apex reaches middle of urosternite
II
; VII-XI uniformly widened, X distinctly shorter than
IX
and
XI

0.20 mm
) than in male, and sides of apical triangle more raised; mesosternal process moderately narrow (about
0.15 mm
), about one third width of coxal cavity, mesepimeron not as narrow (about
0.07 mm
at its widest) as in male.
Elytra
reaching middle of urosternite

;
each elytron rather wider than those of male.
Ratio
of length from front to hind leg 1.0:1.3:2.4 slightly different to that of male; tibiae less sinuate; and metatarsomere I longer than in male, about 1.5 longer than
II

Etymology:
Vestigiepimeron
(a noun phrase in apposition) refers to the very narrow, almost vestigial mesepimeron in the male of this species.
