Scolytocis kiskeyensis Lopes-Andrade sp. nov. ( Figs 45–47 , 60 , 65A , 68A , 74–76 , 81 )

Etymology

The specific epithet refers to Kiskeya (also Quisqueya), an indigenous name for the island of Hispaniola ( Haiti and Dominican Republic), terra typica of this species.

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. Scol. cariborum sp. nov. has several setae at the elytral apex, and Scol. lawrencei sp. nov. has setae at the metaventrite and abdominal ventrites.

Description

Holotype. ( Figs 45–47 ) Measurements in mm: TL 1.00; PL 0.37; PW 0.42; EL 0.63; EW 0.47; GD 0.42. Ratios: PL/PW 0.88; EL/EW 1.33; EL/PL 1.71; GD/EW 0.89; TL/EW 2.11. Body reddish brown; antennae, mouthparts and legs slightly lighter than body. Head shiny, sparsely punctate; punctures fine, interstice smooth. Each antenna ( Fig. 65A ) with nine antennomeres (FL 0.073mm; CL 0.108mm; CL/FL 1.48); length of the antennomeres (in mm) as follows: 0.060; 0.035; 0.035; 0.013; 0.013; 0.013; 0.025; 0.033; 0.050. Eyes with greatest width 1.0X the basal width of scutellum. Pronotum sparsely, finely punctate; puncture deep, separated by a distance of three to five puncture widths; interstice between punctures microreticulate; anterolateral margins straight; posterolateral angles broadly rounded; posterior margin without rugose border. Scutellum shiny, rugose but not microreticulate, bearing one distinct puncture; basal width 0.16X the EW. Elytra with coarse, shallow, subseriate punctation; limits of punctures not well distinct (when seen from above), interstice between punctures smooth; elytral apex rounded, slightly concave, bearing very small, indistinct cuticular globules (best seen in lateral view). Each hindwings ( Fig. 60 ) with apical area without conspicuous pigmented lines. Prosternum concave, without longitudinal carina at midline; surface rugose. Metaventrite glabrous, rugose; discrimen indistinct. Abdominal ventrites glabrous, rugose. Each metatibiae ( Fig. 68A ) near 3X as long as broad; outer apical and outer lateral edges forming an almost perpendicular angle that is rounded; outer edge with spines (around 15) regularly distributed at apical two-thirds. Male genitalia (in paratypes). ( Fig. 74–76 ) Both tegmen and median lobe completely and equally sclerotized, elongate but somewhat globose; median lobe broadly rounded, only 4X as long as broad and larger at middle.

Distribution Known from the Greater Antilles, from Puerto Rico and the Dominican Republic ( Fig. 81 ).

Host fungi Fomes fasciatus (Sw.) Cooke (Polyporaceae) and Ganoderma sp. (Ganodermataceae) .

Comments

The morphology of the male genitalia in this species is unique among all the known Scolytocis . The genitalia of Scol. cariborum sp. nov. has a median lobe with a globose apex, somewhat resembling the one of Scol. kiskeyensis sp. nov.
