Scolytocis cariborum Lopes-Andrade

sp. nov.

Scolytocis cariborum Lopes-Andrade   sp. nov. ( Figs 30–32 View FIGURES 30–32 , 55 View FIGURES 54–56 , 63B View FIGURES 63–65 , 66B View FIGURES 66–68 , 70 View FIGURES 69–71 , 81 View FIGURE 81 )

Etymology The specific epithet refers to the Caribs, native habitants of the island of Dominica.


The species belongs to the lawrencei   species-group, and so is distinguishable from the other Scolytocis   by the smooth posterior margin of pronotum and the concave prosternum. It differs from the other species in the group by the elytral apex with concavity bearing several setae (best seen in lateral view) and distinct morphology of male genitalia.

Description Holotype. ( Figs 30–32 View FIGURES 30–32 ) Measurements in mm: TL 1.21; PL 0.42; PW 0.53; EL 0.74; EW 0.58; GD 0.47.

Ratios: PL/PW 0.80; EL/EW 1.27; EL/PL 1.75; GD/EW 0.82; TL/EW 2.09. Body brown; basal antennomeres, mouthparts and legs yellowish brown. Head with shallow, coarse and sparse punctation; interstice between punctures smooth, shiny, barely microreticulate near margins. Each antenna ( Fig. 63B View FIGURES 63–65 , paratype) with nine antennomeres (FL 0.075mm; CL 0.140mm; CL/FL 1.87); length of the antennomeres (in mm) as follows: 0.068; 0.035; 0.038; 0.013; 0.013; 0.013; 0.043; 0.035; 0.063. Eyes with greatest width 1.33X the basal width of scutellum. Pronotum sparsely punctate; punctures shallow, irregular, separated by a distance of two to four puncture widths; interstice between punctures finely, inconspicuously microreticulate; anterolateral margins slightly arched inwards; posterolateral angles broadly rounded; posterior margin without rugose border. Scutellum impunctate, surface smooth; basal width 0.17X the EW. Elytra with coarse, shallow, subseriate punctation, confuse near apex; border of punctures somewhat indistinct from surrounding surface; interstice between punctures irregular, but not microreticulate; elytral apex subacute; apical region with concavity, which bears several setae (best seen in lateral view); cuticular globules very small, inconspicuous. Each hindwing ( Fig. 55 View FIGURES 54–56 , paratype) with apical area bearing one vague, incomplete pigmented line near the anterior margin. Prosternum concave, rugose. Metaventrite glabrous, finely rugose; discrimen small, one-fifth the length of the metaventrite at midline. Abdominal ventrites bearing some sparse setae; surface finely rugose. Each metatibia ( Fig. 66B View FIGURES 66–68 , paratype) just slightly expanded near apex, more than 4X as long as broad; outer apical and outer lateral edges forming an obtuse rounded angle; spines (around 15) sparse. Male genitalia (in a paratype). ( Fig. 70 View FIGURES 69–71 ) Apex of tegmen (sclerotized three-fourths) subtriangular; median lobe around 1.5X longer than tegmen, with a conspicuous globular apex.

Type series

Holotype. (ANIC) Dominica: /New Florida Estate 2000’ SW slope of Morne Anglais, DOMINICA VI- 11-73 / Cary P. Sheldon Collector / Rigidoporus sp.   / J. F. Lawrence Lot [printed] 3451 [handwritten] / Scolytocis cariborum Lopes-Andrade   HOLOTYPUS [printed on red paper] /. Paratypes. Dominica: 4 specimens (2 ANIC, 2 LAPC), same data as holotype but distinguished labeled / Scolytocis cariborum Lopes-Andrade   PARATYPUS [printed on yellow paper]/.


Measurements in mm (n = 4, including the holotype): TL 1.11–1.21 (1.17 ± 0.05); PL 0.37–0.42 (0.41 ± 0.03); PW 0.47–0.53 (0.49 ± 0.03); EL 0.68–0.79 (0.72 ± 0.05); EW 0.53–0.58 (0.54 ± 0.03); GD 0.47–0.47 (0.47 ± 0.0). Ratios: PL/PW 0.78–0.89 (0.84 ± 0.06); EL/EW 1.27–1.50 (1.34 ± 0.11); EL/PL 1.63–1.88 (1.78 ± 0.12); GD/EW 0.82–0.90 (0.88 ± 0.04); TL/EW 2.09–2.30 (2.17 ± 0.10).

Distribution Known only from Dominica Island ( Fig. 81 View FIGURE 81 ) in the Lesser Antilles province (sensu Morrone 2006).

Host fungi Rigidoporus sp.   ( Meripilaceae   ).


Scol. cariborum   sp. nov. most resembles Scol. kiskeyensis   sp. nov., and both comprise a subgroup of the lawrencei   species-group due to the distinctly sclerotized median lobe that is globose (at least at apex). Both species are confined to the insular Northern Neotropical Region.
