Treatment

Scolytocis lawrencei Lopes-Andrade sp. nov. ( Figs 48–50 View FIGURES 48–50 , 61 View FIGURES 60–62 , 65B View FIGURES 63–65 , 68B View FIGURES 66–68 , 77–78 View FIGURES 77–79 , 80 View FIGURE 80 )

Etymology

The species is named after John F. Lawrence, great coleopterist (and ciidologist) who arranged and organized most of the Xylographellini described in this work.

Diagnosis

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 Neotropical species in the group mainly by the glabrous elytral apex and the slightly setose metaventrite and abdominal ventrites.

Description

Holotype. ( Figs 48–50 View FIGURES 48–50 ) Measurements in mm: TL 1.16; PL 0.42; PW 0.53; EL 0.74; EW 0.58; GD 0.53. Ratios: PL/PW 0.80; EL/EW 1.27; EL/PL 1.75; GD/EW 0.91; TL/EW 2.00. Body brown; basal antennomeres, mouthparts and legs light yellowish brown. Head finely and sparsely punctate; interstice between puncture inconspicuously microreticulate. Each antenna ( Fig. 65B View FIGURES 63–65 , paratype) with nine antennomeres (FL 0.073mm; CL 0.130mm; CL/FL 1.79); length of the antennomeres (in mm) as follows: 0.073; 0.033; 0.035; 0.013; 0.013; 0.013; 0.038; 0.030; 0.063. Eyes with greatest width 1.0X the basal width of scutellum. Pronotum with shallow, coarse, sparse punctation; punctures separate by a distance of two to three puncture widths, interstice microreticulate; anterolateral margins slighted arched inwards; posterolateral angles broadly rounded; posterior margin without rugose border. Scutellum impunctate, microreticulate; basal width 0.19X the EW. Elytra with subseriate punctation; punctures coarser and shallower than those of pronotum, border indistinct from elytral surface (at least when seen from above); interstice between punctures rugose, but without microreticulation; elytral apex subacute, declivity without conspicuous concavity but bearing some small, inconspicuous cuticular globules. Each hindwing ( Fig. 61 View FIGURES 60–62 ) with apical area bearing one vague, incomplete pigmented line near the anterior margin. Prosternum concave, without longitudinal carina at midline; surface shiny, slightly rugose. Metaventrite slightly microreticulate; disc delimited by a circular row of obsolescent punctures; discrimen one-fourth the length of the metaventrite at midline; either side bearing small and sparse setae, each arising from a large obsolescent punctures. Abdominal ventrites bearing small and sparse setae, best seen in lateral view. Each metatibia ( Fig. 68B View FIGURES 66–68 ) just slightly expanded near apex, around 4X as long as broad; outer edge broadly rounded, bearing spines (around 20) regularly distributed at apical two thirds and then getting sparser. Male genitalia (in paratypes). ( Figs 77–78 View FIGURES 77–79 ) Tegmen and median lobe barely sclerotized; tegmen with apex (apical three-fourths) subtriangular; median lobe extremely elongate, more than 10X longer than broad.

Comments

A common and widespread continental Mesoamerican Scolytocis . It co-occurs with Scol. panamensis sp. nov. in Panama, and large specimens of Scol. lawrencei sp. nov. may be confused with it in dorsal view. However, Scol. panamensis sp. nov. belongs to the danielssoni species-group, and is unique among the Scolytocis in the fused antennomeres of the club.
