Dihammaphora paraperforata
sp. nov.
Fig. 12, 13
Dihammaphora perforata
; Wappes et al., 2013: 7, fig. 31 (distr.).
Description of
holotype
.
Male, length
6.40 mm
.
Color
black; gula and prothorax orange.
Head
with frons, clypeus and mandibles densely, but not rugosely, micropunctate; with moderately dense, recumbent white pubescence. Vertex glabrous, with small, dense alveolate punctures.
Antennae
eleven-segmented, passing middle of elytra by one segment. Segments inconspicuously pubescent. Antennomeres III–V subcylindrical, moderately expanded at outer apex, gradually increasing in length (
0.40–0.50 mm
); VI widening from middle to distinctly tumid apex, slightly shorter (
0.45 mm
) than V; VII and VIII moderately serrate; IX–XI subcylindrical (but narrow at base); VII (
0.40 mm
); VIII and IX (
0.35 mm
); X (
0.30 mm
); XI as long as III.
Prothorax
almost cylindrical, one-third longer than wide; widened and weakly rounded for middle third, hardly attenuate, weakly sinuate to front margin, strongly sinuate to base (the latter wider than middle, 1.3 narrower than humeri). Pronotum with some erect, short setae at apical third; surface rendered slightly rugose by evanescent large punctures; latero-basal gibbosities well developed and somewhat acute.
Elytra
almost glabrous (with inconspicuous pubescence at apex); moderately sinuous at sides, narrowest just before middle, subdepressed at base. Dorsal costa present limited to basal third. Surface almost entirely microreticulate, for middle half ornamented with large, deep punctures (most separated by one diameter or less), in four subseriate rows. Margins moderately densely asperate on apical half (at apex asperities larger), absent towards base. Elytral apices rounded-truncate.
Legs
with peduncle of femora distinctly sulcate. Metafemora passing apex of elytra at middle of clave. Metatibiae straight. Apex of protibia with rounded projection laterally. First segment of metatarsus slightly longer than the following two combined.
Male variation.
In one of the
two paratypes
vertex of head partially infused with orange, elytral punctures much smaller, and microreticulation reduced; in the other
paratype
dorsal costa almost reaching to middle of elytra.
Female
(
Fig. 13
). Very similar to male, but puncturation of pronotum less evanescent, more distinctly alveolate; and orange color more rufous (vertex of head rufous-orange in
one paratype
). Prothorax more cylindrical and slightly narrower, less sinuous at sides. Elytra narrowest well before middle; in the two large
paratypes
punctures on elytra larger, and microreticulation much stronger. Metafemora just passing elytral apices. Apex of protibia without rounded projection laterally.
Measurements (mm).
2 males
/
3 females
, total length 5.00–6.40/5.10–6.60; length of pronotum 1.25–2.00/1.20–2.10; width of pronotum 0.85–0.95/0.80–1.00; length of elytra 3.10–3.80/3.00–3.90; width at humeri 1.05–1.25/1.05–1.35.
Diagnosis.
In the key provided by Napp and Mermudes (2010) to the species of
Dihammaphora
with eleven-segmented antennae this new species would run down to couplet 7, which includes
D
.
perforata
(Klug, 1825)
and
D
.
ibirajarai
Mermudes, 1998
.
Dihammaphora paraperforata
differs from
D. perforata
(
Fig. 23
) by the following characters; in
D. paraperforata
base of prothorax distinctly narrower than humeri, hardly attenuate to apex, and latero-basal gibbosities strong and somewhat pointed (in
D. perforata
base of prothorax almost as wide humeri, slightly attenuate to apex, and gibbosities rounded and almost obsolete); in
D. paraperforata
elytra glabrous, not conspicuously sinuous at sides, humero-apical costa nearly reaching apex, with four rows of punctures at middle third, where many punctures separated by less than their own diameter (in
D. perforata
elytra pubescent, conspicuously sinuous at sides, humero-apical costa present only at basal third, with three rows of punctures at middle third, where punctures separated by their own diameter or more); in
D. paraperforata
metatibia is straight (in
D. perforata
sinuate); in
D. paraperforata
mesosternum is black (in
D. perforata
red). Females of
D. paraperforata
differ from those of
D. perforata
by the apical antennomeres not serrate and rather narrow, XI as long as or longer than III (in
D. perforata
subserrate and somewhat swollen, XI shorter than III).
Dihammaphora paraperforata
differs from
D
.
ibirajarai
by the following characters in males; in
D. paraperforata
clypeal suture rather weak (in
D
.
ibirajarai
suture missing); in
D. paraperforata
antennomeres III–V almost filiform, equally and only moderately wider at apex, VI slightly shorter than V (in
D
.
ibirajarai
III
–V subserrate, sequentially more expanded at apex, VI as long as V); in
D. paraperforata
basal gibbosities of pronotum prominent and somewhat pointed (in
D
.
ibirajarai
rounded and feebly prominent); in
D. paraperforata
peduncle of femora distinctly sulcate, and metafemora passing apex of elytra near middle of clave (in
D
.
ibirajarai
peduncles barely sulcate, and metafemora reaching elytral apex); in
D. paraperforata
metatarsomere I slightly longer than II+III (in
D
.
ibirajarai
as long as II+III).

Comment.
The Bolivian record for
D. perforata
(Wappes
et. al.
2013) was due to a misidentification; their illustration shows it to be
D. paraperforata
.
Etymology.
The species epithet,
paraperforata
, is a compound of the Latin “para” meaning a different form of
perforata
.
