An essay on the tribe Xylographellini (Coleoptera: Tenebrionoidea: Ciidae) Author Lopes-Andrade, Cristiano text Zootaxa 2008 2008-07-30 1832 1 1 110 https://biotaxa.org/Zootaxa/article/view/zootaxa.1832.1.1 journal article 10.11646/zootaxa.1832.1.1 1175­5334 5126979 45A82AD6-F369-4A74-A280-048BAE6E2DA5 Scolytocis danielssoni Lopes-Andrade sp. nov. ( Figs 33–35 , 56 , 63C , 66C , 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 ) 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 , 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 ) 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 , 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.

Comments Among the Scolytocis examined, this new species occurs at the highest known altitude ( type locality, Cerro de la Muerte, 3200m over the sea).
