Scolytodes pseudolepidus Jordal and Smith

sp. nov.

Scolytodes pseudolepidus Jordal and Smith   , sp. nov.

( Figs 74, 77, 80 View FIGURES 73–81 )

Type material. Holotype, female: Ecuador: Napo Prov., Res. Ethnica Waorani, 1km S Onkone Gare Camp., Trans. Et. , 00°39’10’’S, 76°26’W, 220m elev., October 1995, T.L. Erwin et al. collectors, indiv #000963 GoogleMaps   . Holotype temporarily held in trust at USNM for MECN   .

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.
