Scolytocis paschoali Lopes-Andrade sp. nov. ( Figs 1–4 , 88–90 , 93 , 94C, 95C , 99–101 )

Etymology

The species is named after Paschoal Coelho Grossi, entomologist, good friend, and great collector of ciids.

Diagnosis

The species belongs to the fritzplaumanni species-group and so it is distinguishable from the other Scolytocis by the biconcave prosternum without longitudinal carina at midline, and the smooth border of the posterior pronotal margin. It differs from the other species in the group by the combination of a fine and sparse pronotal punctation and a large antennal club (2X longer than funicle).

Description

Holotype. ( Figs 88–90 ) Measurements in mm: TL 1.70; PL 0.60; PW 0.75; EL 1.10; EW 0.85; GD 0.75. Ratios: PL/PW 0.80; EL/EW 1.29; EL/PL 1.83; GD/EW 0.88; TL/EW 2.00. Body black, almost entirely glabrous; legs brown; antennae, mouthparts and tarsi yellowish brown. Head coarsely punctate; punctures small, with interstice microreticulate. Each antenna ( Fig. 94C ) with nine antennomeres (FL 0.093mm; CL 0.190mm; CL/FL 2.05); length of the antennomeres (in mm) as follows: 0.105; 0.045; 0.050; 0.013; 0.015; 0.015; 0.053; 0.053; 0.085. Eyes with greatest width 1.5X the basal width of scutellum. Pronotal punctation sparse; punctures shallow and narrow, separated by a distance of one to three puncture widths; interstice between punctures finely and conspicuously microreticulate; anterolateral margins straight; posterolateral angles broadly rounded; posterior margin without a rugose border. Scutellum impunctate, but microreticulate; basal width 0.14X the EW. Elytra with confuse punctation, coarser and denser than that of pronotum; punctures deep, usually separated by a distance of two puncture widths or less; interstice between punctures smooth, shiny; elytral apex truncate, apical border slightly concave when seen from above, bearing small, sparse cuticular globules. Each hindwing ( Fig. 93 ) with apical area bearing two distinct pigmented lines, one near the anterior margin and the other almost reaching the posterior margin. Prosternum biconcave, with very narrow longitudinal carina at midline; surface shiny, inconspicuously rugose. Metaventrite glabrous; disc finely microreticulate, with discrimen half of its length at midline; either side bearing some large obsolescent punctures, with interstice microreticulate to striated. Abdominal ventrites glabrous, microreticulate. Each metatibia ( Fig. 95C ) broadly rounded, around 3X as long as broad; outer apical and outer lateral edges forming an obtuse rounded angle; outer edge with spines (around 20) close to each other at the apex and getting sparser until its base. Male genitalia (in paratypes). ( Fig. 99–100 ) Apical portion of tegmen with sides subparallel; median lobe slightly longer than tegmen.
