Scolytocis indecisus Lopes-Andrade

sp. nov.

Scolytocis indecisus Lopes-Andrade   sp. nov. ( Figs 42–44 View FIGURES 42–44 , 59 View FIGURES 57–59 , 64C View FIGURES 63–65 , 67C View FIGURES 66–68 , 73 View FIGURES 72–73 , 80 View FIGURE 80 )

Etymology The specific epithet refers to my indecision in choosing the name of this new species.


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. Scol. danielssoni   sp. nov. has finer pronotal punctation and interstices of punctures shiny, Scol. panamensis   sp. nov. has a distinct antennal club (with only one broad antennomere) and Scol. howdeni   sp. nov. has closer pronotal punctation.


Holotype. ( Figs 42–44 View FIGURES 42–44 ) Measurements in mm: TL 1.42; PL 0.47; PW 0.58; EL 0.89; EW 0.68; GD 0.63. Ratios: PL/PW 0.82; EL/EW 1.31; EL/PL 1.89; GD/EW 0.92; TL/EW 2.08. Body shiny dark-brown, with head and pronotum darker than elytra; antennae, mouthparts and legs yellowish brown. Head coarsely punctate, with interstice between punctures microreticulate. Each antenna ( Fig. 64C View FIGURES 63–65 , paratype) with nine antennomeres (FL 0.095mm; CL 0.145mm; CL/FL 1.53); length of the antennomeres (in mm) as follows: 0.068; 0.038; 0.050; 0.015; 0.015; 0.015; 0.038; 0.040; 0.068. Eyes with greatest width 1.0X the basal width of scutellum; ommatidia with irregular surface. Pronotum with deep and coarse punctation; punctures separated by a distance of one to two puncture widths, some areas of the disc with sparser punctation; interstice between punctures inconspicuously microreticulate, shiny; anterolateral margins straight; posterolateral angles broadly rounded; posterior margin with a rugose border along it. Scutellum glabrous, impunctate, shiny, basal width 0.13X the EW. Elytra with confuse punctation, slightly coarser than that of pronotum; punctures deep, with interstice smooth and shiny; elytral apex truncate, slightly concave when seen from above, bearing small, inconspicuous cuticular globules. Each hindwing ( Fig.59 View FIGURES 57–59 ) extremely membranous, probably not or barely functional for flight; apical area without conspicuous pigmented lines. Prosternum biconcave, with a narrow longitudinal carina at midline; surface rugose. Metaventrite with rugose surface; disc delimited by a circular row of punctures; discrimen absent; either side bearing small and sparse setae, each arising from large obsolescent punctures. Abdominal ventrites with rugose surface and bearing small and sparse setae. Each metatibia ( Fig. 67C View FIGURES 66–68 , paratype) near 3.2X as long as broad; outer apical and outer lateral edges forming an obtuse angle that is broadly rounded; outer edge with spines (around 20) regularly distributed and more close to each other at apical two-thirds, then getting sparser. Male genitalia (in a paratype). ( Fig. 73 View FIGURES 72–73 ) Tegmen with apex (sclerotized apical half) subpentagonal, basal half extremely membranous; median lobe as long as tegmen.
