Etymology The specific epithet is in honour of the great entomologist Floyd Gerald Werner (1921-1992), who col- lected the known specimens of the species. He also collected the known specimens of
Scol. thayerae
sp. nov.
and
Xylographella speciosa
sp. nov.
, all during the Philippine Zoological Expedition (1946 to 1947), sponsored by the Chicago Museum of Natural History (now the Field Museum of Natural History).
Diagnosis
The species belongs to the
werneri
species-group, and so is distinguishable from the other
Scolytocis
by the combination of a concave prosternum and the presence of a rugose border along the posterior margin of pronotum. It differs from
Scol. novaezelandiae
, the other species of the group, by its narrower rugose border of pronotum and the metaventrite bearing a long discrimen.
Description
Holotype
.
(
Figs 114–116
) Measurements in mm: TL 1.26; PL 0.42; PW 0.53; EL 0.84; EW 0.58; GD 0.58. Ratios: PL/PW 0.80; EL/EW 1.45; EL/PL 2.00; GD/EW 1.00; TL/EW 2.18. Body dark brown; antennae, mouthparts and legs yellowish brown. Head sparsely punctate; interstice between punctures inconspicuously microreticulate, shiny. Each antenna (
Fig. 127B
) with nine antennomeres (FL
0.07mm
; CL
0.12mm
; CL/FL 1.59); length of the antennomeres (in mm) as follows: 0.067; 0.037; 0.033; 0.013; 0.013; 0.013; 0.033; 0.030; 0.053. Eyes with greatest width 1.3X the basal width of scutellum. Pronotum with coarse, sparse punctation; punctures irregular, separated by a distance of one to three puncture widths; interstice between punctures finely microreticulate. Scutellum impunctate, rugose; basal width 0.14X the EW. Elytra with confuse punctation, coarser and denser than that of pronotum; interstice between punctures smooth to slightly rugose, shiny, but not microreticulate; elytral apex truncate, declivity slightly concave and bearing small, inconspicuous cuticular globules. Each hindwing (
Fig. 124
) with apical area without conspicuous pigmented line, but one vague, inconspicuous line near the posterior margin. Prosternum concave, without longitudinal carina at midline; surface finely rugose. Metaventrite bearing a distinct discrimen along its midline, beginning at the posterior margin and almost reaching the anterior; surface finely granulose at disc and rugose on either side. Abdominal ventrite glabrous, finely microreticulate. Each metatibia (
Fig. 129B
) near 3X as long as broad; outer apical and outer lateral edges forming an obtuse angle that is broadly rounded; apex with outer edge bearing almost 15 spines very close to each other, outer lateral edge with near five spines regularly distributed.
Male genitalia (in a
paratype
).
(
Fig. 133
) Median lobe subcylindrical, membranous, elongate, as long as tegmen; tegmen with lateral margins converging from the middle to the apex.
