Scolytocis philippinensis Lopes-Andrade sp. nov. ( Figs 108–110 , 122 , 126C , 128C , 131 , 134 )

Etymology The specific epithet refers to the Philippines, terra typica of this species.

Diagnosis

The species belongs to the zimmermani species-group, in which the species have each tibia expanded to the middle, with its outer margin broadly rounded and bearing several spines very close to each other at the apical half. It differs from both Scol. thayerae sp. nov. and Scol. zimmermani sp. nov. by its smaller apical antennomere and body.

Description

Holotype. ( Figs 108–110 ) Measurements in mm: TL 1.37; PL 0.47; PW 0.58; EL 0.84; EW 0.63; GD 0.63. Ratios: PL/PW 0.82; EL/EW 1.33; EL/PL 1.78; GD/EW 1.00; TL/EW 2.17. Body with dorsal surface dark reddish brown, ventral surface light reddish brown; basal antennomeres and funicle yellowish brown; labial palpi, maxillary palpi and club brown. Head finely and sparsely punctate on dorsum; interstice between punctures microreticulate, shiny. Each antenna ( Fig. 126C ) with nine antennomeres (FL 0.08mm; CL 0.17mm; CL/FL 2.04); length of the antennomeres (in mm) as follows: 0.107; 0.033; 0.040; 0.017; 0.013; 0.013; 0.040; 0.050; 0.080. Eyes with greatest width 1.14X the basal width of scutellum. Pronotum with shallow punctation; punctures fine, separated by a distance of three to five puncture widths; interstice between punctures finely microreticulate; anterolateral margins slightly arched inwards; posterolateral angles broadly rounded; posterior margin without rugose border. Scutellum impunctate, inconspicuously microreticulate; basal width 0.19X the EW. Elytra with confuse and dense punctation; punctures coarser and shallower than those of pronotum, each one with the border indistinct from surrounding surface (when seen from above); interstice between punctures rugose, but without microreticulation; elytral apex rounded, declivity with shallow concavity and bearing small cuticular globules. Each hindwing ( Fig. 122 ) with apical area bearing one incomplete pigmented line near the anterior margin. Prosternum biconcave, with conspicuous longitudinal carina at midline; rugose. Metaventrite glabrous; disc smooth, delimited by a circular row of obsolescent punctures; either side rugose, bearing some large obsolescent punctures; discrimen half the length of the metaventrite at midline. Abdominal ventrites almost glabrous, finely rugose. Each metatibia ( Fig. 128C ) conspicuously expanded at middle, near 3.5X as long as broad; outer margin broadly rounded, equally spinulose from apex to middle, with spines separated by a distance of one spine width, and spines then getting sparse to the base. Male genitalia (in a paratype). ( Fig. 131 ) Median lobe subcylindrical, membranous, elongate, as long as tegmen; tegmen with lateral margins gradually converging from base to apex.
