Diagnosis.
Interstriae 10 sharply elevated to near apex. Protibiae with an additional mesal tooth. Elytra with erect setae on odd-numbered interstriae. Ventral vestiture largely bifid to plumose. Most closely related to
S. lepidus
Wood, 1975
, but differs by the much less abundant setae in the female frons, and by the regular presence of erect setae on all odd-numbered interstriae.
Description, female.
Length
2.1 mm
, 2.3 × as long as wide; colour dark brown.
Head
. Eyes entire, separated above by 2.2 × their width. Frons concave between eyes from upper level of eyes to epistoma, finely punctured in impressed area except impunctate and shiny at level of antennal insertion; vestiture consisting of scant long setae arising from margin of concave area, and much shorter and finer setae within impressed area. Antennal club with two obliquely procurved sutures, segment 1 and 2 partially corneous. Funiculus 6-segmented.
Pronotum
reticulate, with dense, deep punctures on posterior half, punctures more shallow and smaller on anterior half, mixed with distinct asperities, anterior row of asperities forming a faint wavy rim. Vestiture consisting of few short recumbent setae and at least eight long, erect setae (4-2-2).
Elytra
smooth, shiny; striae regular, punctures moderately large, deep, spaced by their diameter; interstrial punctures slightly smaller, confused; interstriae 10 sharply elevated to near apex. Vestiture consisting of erect, slightly spatulate, setae on odd-numbered interstriae, particularly on posterior half and sides.
Legs.
Procoxae separated by 0.5 × the width of one procoxa. Mesocoxae separated by 0.8 × the width of a procoxa. Protibiae narrow, distal tooth 1 and 2 subequal, with 3–4 lateral spines or rugae decreasing in size towards tibial base; an additional mesal tooth present on its posterior face; protibial mucro short, obtuse. Meso- and metatibiae with 6 lateral, long, socketed teeth on distal half.
Ventral vestiture
. Setae on mes- and metanepisternum mixed bifid to plumose, on metasternum largely bifid except simple on posterior half.
Male.
Not known.
Key (
Wood 2007
).
Keys to couplet 62,
S. lepidus
, but differs as noted in the diagnosis.
Etymology.
The combination of the Latin adjective
lepidus
, meaning glamorous, and the Latin prefix
pseudo
- (derived from ancient Greek), meaning false, refers to the similarity to
Scolytodes lepidus
.
Biology and distribution.
Only known from the
type
locality in the Ecuadorian Amazon rainforest. The specimens were collected by canopy fogging.
