Description
anterior angles; length of mandible equal to that of head, fi nely and densely punctured,
punctures slightly smaller than those on disc of head, becoming slightly coarser
at apices; apices of mandible trifurcate; mandible in major male (Fig. 5) robust with
a large tooth on inner edge just above the middle (see Santos-Silva 2002:36), size of
sub-median tooth more or less equal to that of dorsal inner apical tooth which is in
turn slightly shorter than terminal element but longer and broader than ventral apical
tooth, ventral tooth (not visible when viewed dorsally) small and somewhat indistinct,
apical teeth may be worn or broken; mandible in minor male (Fig. 6) less robust, submedian
inner tooth broadly fl attened, width twice that of inner apical tooth, outer
margin of sub-median tooth weekly emarginated; there is also a large basal tooth which
is similar in size to sub-median tooth but this is only visible if the jaws are widely open;
mandibular dorsal carina distinct, elevated from the base of mandible to just beyond
sub-median inner tooth, inner edge of mandible with a fringe of long, pale, setae
which project beyond margin and over sub-median tooth. Dorsal surface of the head
(Figs 5, 6) more or less evenly convex with a weak median longitudinal sulcus, disc
moderately and fi nely punctured, punctures irregular, size and distribution similar to
that on disc of pronotum, becoming distinctly larger and coarser towards the ocular
carina and occiput, post occipital area and genae coarsely and abundantly punctuate,
size of punctures at least three times that of largest on pronotum (maybe confl uent
in places), dense punctuation extending beneath head to gula which is medially impunctate;
dorsal ocular carina distinct, moderately elevated, extending from mid level
of eye to base of jaw, width more or less equal to the base of mandibular carina. Frons
weakly depressed at sides, prior to anterior margin, resulting in a slight median, transverse
ridge at level of anterior margin of antennal insertions. Clypeus weakly elevated
medially with a strong median projection; projection at least three times wider than
long; anterior margin weakly emarginated. Eye (Fig 8) very weakly emarginated; posterior
ocular edge very distinct; length of eye twice that of median width, when viewed
laterally; ventral ocular lobe only slightly broader than dorsal lobe. Sub-mentum with
similar strong, dense punctuation, elevation of sub-mentum more of less equal to that
of genae, delimited behind by a shallow transverse sulcus, punctures with a long pale
seta which is at least fi ve times the length of the puncture. Carina of ventral sensorial
area of the antennomeres III-XI (Figs 8, 9) distinctly elevated, visible from the side; pilosity
of the antennomeres III-XI pale, distinct, longest setae forming posterior fringe
on segments, setal length almost equal to that of segment.
Pronotum (Figs 5, 6) transverse, somewhat fl attened dorsally, maximum width
at anterior angles, being slightly greater than that of elytra at humeri, anterior angles
rounded not strongly projected; anterior margin very weakly concave; posterior margin
weakly sinuate; lateral margins narrow but well defi ned, becoming gradually but distinctly
concave after anterior third with minimum width just prior to posterior angles that are weakly projected; disc fi nely and irregularly punctuate, punctures fi ner than
those on disc of head, becoming gradually larger towards margins, largest punctures
not greater than those on anterior area of head. Elytron 3.8 times longer than broad,
maximum width at humeri, becoming only slightly narrowed just prior to apex which
is broadly rounded; surface adjacent to median suture fi nely punctate, punctures equal
in size to smallest on disc of pronotum, distribution irregular, punctures on average
4–5 times their own width apart becoming slightly larger and denser sub-laterally below
humeral third. Metepisternum distinctly and irregularly punctuate, punctures of
similar size or slightly smaller than those on adjacent area of metasternum, becoming
denser near anterior margin; punctures on metasternum large and distinct adjacent
to metepisternum 2.3 times their own width apart, becoming distinctly fi ner towards
metasternal suture. Apical ventrite of abdomen only slightly longer than preceeding
segment, more distinctly punctured than rest of abdomen with long pale sub-erect
setae. Femora minutely and indistinctly punctured throughout, setae minute and indistinct.
Tibiae becoming strongly dilated towards apex, width at apical margin at least
4× that at base, punctures minute, as on femora, setae minute just extending beyond
margins of punctures, ventral fringe short; protibiae somewhat fl attened giving narrow,
sharp dorsal edge. Metatarsomere V approximately as long as I–III combined.
Body length (including mandibles) 10.3–18.7 mm; prothorax: length 2.2–3.3 mm;
anterior width, 3.0–4.8 mm; posterior width, 2.5–4.0 mm; elytral length, 6.2–11.5 mm.
Female (Fig. 3). Head less robust, width plus eyes slightly narrower than that of
pronotum at anterior angles. Eyes slightly broader and less pronounced than in male.
Mandible (Fig. 7) subtriangular, length equal to two thirds that of head, more coarsely
punctured than in male, punctures on dorsal surface irregular, largest equal in size to
post ocular punctures; dorsal carina present but less well defi ned than in male; ventral
apical tooth small (not visible dorsally); dorsal inner edge with small rounded preapical
tooth, basal half with a broad fl attened, weakly sinuate tooth which is slightly more
pronounced on left mandible. Clypeal projection not broader than long, distinctly
narrowing towards apex. Pronotum (Fig. 7) similar to male but with anterior two
thirds slightly more rounded at sides prior to becoming narrowed and with anterior angles
less pronounced. Apical ventrite of abdomen twice length of preceeding segment,
puncturation slightly denser than in male and setae shorter.
Body length (including mandibles) 15.0–18.7 mm; prothorax: length 3.2–3.7
mm; anterior width, 4.1–4.6 mm; posterior width, 3.5–4.3 mm; humeral width, 4.1–
5.1 mm; elytral length, 9.0–11.1 mm.
