Dindymus (Dindymus) wynigerae sp. nov.

( Fig. 7 )

Type material. HOLOTYPE: ♀, ‘ Indonesien, Flores [ Insel], Moni , 800-1200 m, 24.III.1984, E. M. Braunwalder’ ( NHMB).

Description. Female. Head, antennae (except basal third of antennomere IV), labium, callar lobe, scutellum, legs including coxae, sternum including epicoxal lobes, large ventral spot (with clear outline) on base of abdomen, narrowing and reaching towards ventrite VII, black. Pronotal lobe dark brown. Clavus and base of corium dark brown, becoming gradually lighter with a wine-red touch to light yellow at level of median vein on membrane, base up to apex of corium light grey, distal part of membrane black. Ventrites including genitalia yellow to orange. Basal third of last antennomere whitish.

Head anterior and posterior of eyes protruding, in frontal view markedly and evenly elevated above eyes, in lateral view somewhat rounded ventrally. Eyes only little convex, tempus protruding towards vertex, which is rather large and separated from frons by rounded furrow. Pronotum narrow both basally and anterolaterally (here more narrow than head including eyes). Lateral margins of pronotum thinner, markedly bent upwards, anterior angles not protruding to front, distinctly sinuate around midlength, well rounded in front of base. Base of costal margin not very wide, body almost pear-shaped, widest behind claval apex. Fore femur with one great, outer denticle and one smaller, inner denticle.

Puncturation on pronotal lobe and mesoscutum on entire surface very dense and conspicuous, clavus and corium except apex colourless and dwindling.

Female genitalia. Both sides of valvifer I touching only slightly at base, its upper margin running in parallel with distal margin of ventrite VII (more or less bordering it), and feebly depressed; laterotergite IX large and high (reaching up to short valvifer I) with large depression and from both sides covering valvifer II. Tergite VIII and anal tube markedly overlapping ventrite VII in lateral view.

Measurements (mm). Holotype female. Body length 12.80. Head: width (including eyes) 2.02, interocular width 1.24. Antenna: antennomere I 3.24, antennomere II 2.21, antennomere III 2.00, antennomere IV 2.75. Pronotum: length 2.16, width 3.40. Scutellum: length 1.46, width 1.73. Corium: length 5.78, width 2.32.

Differential diagnosis. The new species is similar to D. nigellus Distant, 1888 , and D. longicollis Blöte, 1931 , from the Oriental region in the shape of its head, i.e., the head long and narrow, eyes a little convex and rather far from the pronotum; as well as in its pronotum, which is narrow both proximally and distally, the callar lobe being without any medial protuberances. The new species can be easily recognized, as the corium is entirely pale (whitish or yellowish) in the two above-mentioned species whereas in the new one it is dark brown except a wider apical band of lighter colour.

Etymology. We name the species in honour of Denise Wyniger, Naturhistorisches Museum, Basel (now in Natur-Museum, Luzern), who lent us the material of Pyrrhocoridae for study.

Distribution. Indonesia ( Flores Island).
