Treatment

Scolytocis danielssoni Lopes-Andrade sp. nov. ( Figs 33–35 View FIGURES 33–35 , 56 View FIGURES 54–56 , 63C View FIGURES 63–65 , 66C View FIGURES 66–68 , 80 View FIGURE 80 )

Etymology

The species is named after Dr. Roy Danielsson, curator of the Entomological Collection of MZLU. The loan of a large number of ciids of MZLU has been very important to conclude a series of works on the Ciidae systematics, and two specimens of this new species were found among the specimens he sent me.

Diagnosis

The species belongs to the danielssoni species-group, and so it is distinguishable from the other Scolytocis species by the biconcave prosternum with a narrow longitudinal carina at midline, the rugose border along the posterior pronotal margin and the comparatively large tibiae. It differs from Scol. howdeni sp. nov. and Scol. indecisus sp. nov. by the fine and sparse pronotal punctation, and the lack of microreticulation at the interstice between punctures. It differs from Scol. panamensis sp. nov. by the distinct separation of the three antennomeres of the club.

Description

Holotype. ( Figs. 33–35 View FIGURES 33–35 ) Measurements in mm: TL 1.68; PL 0.58; PW 0.74; EL 1.00; EW 0.79; GD 0.68. Ratios: PL/PW 0.78; EL/EW 1.27; EL/PL 1.72; GD/EW 0.86; TL/EW 2.13. Body shiny black; upper and ventral surfaces subglabrous. Head with dorsum smooth, shiny, sparsely punctate. Each antenna ( Fig. 63C View FIGURES 63–65 , paratype) with nine antennomeres (FL 0.143mm; CL 0.175mm; CL/FL 1.23); length of the antennomeres (in mm) as follows: 0.06; 0.050; 0.063; 0.028; 0.025; 0.028; 0.048; 0.050; 0.078. Eyes with greatest width 1.5X the basal width of scutellum. Pronotum punctate; punctures sparse, small, deep, uniform in size, separated by a distance of two to three puncture widths; interstice between punctures smooth, shiny; anterolateral margins straight; posterolateral angles broadly rounded; posterior margin with a conspicuous, narrow rugose border along it. Scutellum glabrous, impunctate, shiny; basal width 0.11X the EW. Elytral punctures slightly coarser than those of pronotum; interstice between punctures smooth and shiny; elytral apex truncate, bearing a distinct concavity when seen from above; cuticular globules very small, inconspicuous. Each hindwing ( Fig. 56 View FIGURES 54–56 ) with apical area bearing two distinct pigmented lines, one near the anterior margin and the other almost reaching the posterior margin. Prosternum biconcave, with a narrow longitudinal carina at midline; surface rugose. Metaventrite disc delimited by a circular row of obsolescent punctures, microreticulate; discrimen inconspicuous, being just a small impression restricted to the very base of the metaventrite; either side bearing small and sparse setae, each arising from a large obsolescent puncture, with interstice microreticulate. Abdominal ventrites bearing some small and sparse setae. Each metatibia ( Fig. 66C View FIGURES 66–68 , paratype) slender, more than 4X as long as broad; outer apical and outer lateral edges forming an obtuse rounded angle; outer edge with spines (around 20) regularly distributed at apical two-thirds and then getting sparser. Male genitalia. Unknown.
