Scolytocis zimmermani Lopes-Andrade 2008, sp. nov.

Scolytocis zimmermani Lopes-Andrade sp. nov. (Figs 117–119, 125, 127C, 129C, 135)

Etymology

The species is named after the outstanding entomologist Elwood Curtin Zimmerman (1912-2004), who collected the three known specimens of the species.

Diagnosis

The species belongs to the zimmermani species-group, in which the species have each tibia expanded to the middle, with its outer margin broadly rounded and bearing several spines very close to each other at the apical half. It differs from Scol. thayerae sp. nov. mainly by its smaller body (less than 1.7mm) and from Scol. philippinensis sp. nov. by the conspicuous larger apical antennomere.

Description

Holotype. (Figs 117–119) Measurements in mm: TL 1.58; PL 0.63; PW 0.68; EL 0.89; EW 0.68; GD 0.68. Ratios: PL/PW 0.93; EL/EW 1.31; EL/PL 1.41; GD/EW 1.00; TL/EW 2.32. Body with dorsum dark brown, ventral surface reddish brown; basal antennomeres, mouthparts and tarsi yellowish brown. Head finely and sparsely punctate on dorsum; interstice between punctures smooth, shiny, rugose near the anterior margin. Each antenna (Fig. 127A) with nine antennomeres (FL 0.113mm; CL 0.195mm; CL/FL 1.73); length of the antennomeres (in mm) as follows: 0.100; 0.043; 0.065; 0.020; 0.015; 0.013; 0.045; 0.050; 0.100. Eyes with greatest width 1.11X the basal width of scutellum. Pronotum with shallow punctation; punctures fine at disc, separated by a distance of two to three puncture widths; near the lateral margins, the punctures are coarse and somewhat elongate, separated by one puncture width or less, but not coalescent; interstice between punctures finely and inconspicuously microreticulate; anterolateral margins straight; posterolateral angles broadly rounded; posterior margin without a rugose border. Scutellum impunctate, shiny; basal width 0.21X the EW. Elytra with confuse punctation, which is shallower, denser and coarser than that of pronotum; interstice between punctures smooth, shiny; elytral apex truncate; apical declivity concave, with inconspicuous cuticular globules. Each hindwing (Fig. 125) with apical area bearing two distinct pigmented lines, one near the anterior margin and the other almost reaching the posterior margin. Prosternum concave, without longitudinal carina at midline; surface finely rugose. Metaventrite glabrous, with disc delimited by a circular row of obsolescent punctures, finely microreticulate; either side microreticulate, and bearing some obsolescent punctures; discrimen one-sixth the length of metaventrite at midline. Abdominal ventrites glabrous, finely microreticulate. Each metatibia (Fig. 129C) conspicuously expanded at middle, 3.5X as long as broad; outer margin broadly rounded, equally spinulose from apex to middle, with spines very close to each other and then getting sparse to the base. Male genitalia. Unknown.

Comments

Although the morphology of male genitalia is not provided for this species, it is sufficiently different to allow the description at this moment.
