Euscopus rubens sp. nov.

( Fig. 7 )

Type material. HOLOTYPE: ♀, ‘ North Sumatra, Brestagi, 76 km from Medan , 30.III.-1.IV.1996, S. Bečvář leg.’ ( PPUA).

Description. Body mainly red. Head, pronotal collar, callar and pronotal lobe, membrane (except base), sternum and zygosternites, extreme apex of antennomere III, extreme base and distal third of antennomere IV and tarsi black. Trichobothrial areas velvet black. Median spot on vertex and pronotal collar, antennomeres I-III, labium, lateral margin of pronotum, basal third of pronotum (medially prolonged towards callar lobe), pronotal epipleuron, apex of scutellum, claval suture, apex of clavus, entire corium including hypocostal lamina, legs (including coxae) and dorsal outer and ventral laterotergites red. Base of membrane grey, antennomere IV (except base and apical part) whitish.

Head rather wide; medial longitudinal furrow on frons less apparent. Pronotum rather narrow, towards base only slightly widening; lateral margin of pronotum on level of median furrow, very slightly sinuate, in lateral view its edge rounded rather than sharp. Fore femora with small denticle at midlength, apex with one large and one small denticle. Sides of corium almost parallel, scarcely widening at level of claval apex.

Head, pronotal collar, furrow around callar lobe, sternum and ventrites with silvery pubescence, pubescence on ventral surface of body larger and denser. Pronotal lobe, mesoscutum, mesoscutellum (except top), clavus, and corium (except costal margin) with black punctures.

Measurements (mm). Holotype female. Body length 9.50. Head: width (including eyes) 1.97, interocular width 1.10. Antenna: antennomere I 1.90, antennomere II 1.90, antennomere III 0.84, antennomere IV 1.15. Pronotum: length 2.00, width 3.21. Scutellum: length 1.5, width 1.97. Corium: length 4.97, width 1.78.

Differential diagnosis. Euscopus rubens sp. nov. differs from other species of the genus with a red corium (i.e., E. rufipes Stål, 1870 , E. vittiventris Walker, 1872 , E. chinensis Blöte, 1931 , E. major Stehlík & Jindra, 2003 , and E. parvimacula Stehlík, 2004 ) by lacking a medial black spot on the corium (as well as a spot on its apex) and by having red rather than black antennomeres I-III (except base of antennomere III). In E. parvimacula , whose antennomeres I-III are also red, the forewing membrane is grey with a black base rather than the opposite in E. rubens sp. nov.

Etymology. The specific epithet is the Latin adjective rubens (= reddish).

Distribution. Indonesia: Sumatra.
