Etymology

This species is named to honour the prominent heteropterologist Dr. Randall T. Schuh (American Museum of Natural History, New York, United States of America).

Description

Male. Body red with pale and brown areas, body length 3.40–3.53 mm, width 1.85– 1.92. Head pale with red patches, two small spots on vertex and one large patch anterior to these. Frons pale with small red patches on sides, mandibular plate and clypeus pale with small red patches. Head length, in dorsal view, 0.52 mm, width 0.64–0.67 mm, diameter of eye 0.18 mm. First antennal segment pale yellow, slightly tinged with red. Second antennal segment yellow, pale brown basally, slightly tinged with red, with yellow ring and small, brown patch mesially, slightly darker apically, covered with short, pale setae. Third segment brown, darkened towards apex, covered with very thin, short, white, setae. Fourth segment dark brown, covered with white, shining, protruding setae, longer than its diameter. Length of antennal segments in mm: 0.13–0.14: 0.29–0.33: 0.68–0.73: 0.20. Rostrum brown, shining, length of rostral segments in mm: 0.27: 0.23: 0.22: 0.22.

Pronotum pale yellow, mottled with red, with two large, pale brown patches contiguous to posterior margin of pronotum. Lateral margins translucent, pale yellow, with four small, dark red patches along its external sides. Length of pronotum 0.30 mm, lateral margins 0.55 mm, posterior margin 1.30 mm. Mesoscutum red with paler patches, tinged with brown on sides. Scutellum pale grey­brown, red on sides, with red longitudinal stripe paler mesially; apex of scutellum grey­brown.

Hemelytra covered with dense, short, silvery, shining, scale­like pilosity; exocorium pinkish with darker reddish patches, also covered with dark brown or black, short, scalelike setae. Corium with characteristic brown pattern ( Fig. 1 View FIGURE 1 ), red in part contiguous with the claval suture. Clavus red, slightly paler along suture, with a rib­like claval vein. Cuneus pink with small, darker patches on margin, covered with silvery and dark brown scale­like setae. Row of silvery, erect setae perpendicular to inner margin of cuneus. Membrane grey, venation pale brown, partly tinged with red.

Underside of body pale yellow, abdomen yellowish with transverse red bands on segments. Ostiolar peritreme pale yellow. Coxae, trochanters, and femora (except for apical portion) yellowish­brown; apices of femora red with pale ring or patch; trochanters with red or brown rings, tarsi pale brown.

Lateral margins of the pygophore ( Figs 6–7 View FIGURES 6 – 9 ) concave medially on the right side, distally on the left one. Posterodorsal margin broadly and deeply, but gradually emarginate, posteroventral margin suddenly and deeply emarginate in the middle. Both the emarginations filled by dorsal and ventral membraneous lobes, respectively, their exact shape and identity (membranous extensive proctiger or intersegmental membrane 9–10) not ascertained with certainty. Left posterolateral edge of pygophore subtriangularly produced, the right one forming a lobe beneath articulation of the right paramere. Posterodorsal margin with a strong marginal apodeme, complex systems of apodemes at basis of each paramere. Parameres’ shape as illustrated ( Figs 8–9 View FIGURES 6 – 9 ), the right one larger, longer and more complex than the left one, its articulation more dorsal. In natural position both parameres protruding from the pygophore, the left one directed posterad, the right one transverse, crossing over the left one in dorsal view. Suspensorial apodemes (not illustrated) unusually long, and unusually strongly sclerotized. Phallus (Figs 10, 11) very small, in resting position (all the attempts of erection failed) inversely U­shaped, phallobase without particulars. The distal part of the phallus enveloped by transparent theca provided with a distal opening. Endosoma formed by a simple conjunctiva, and a vesica occupying nearly all the dorsal lobe of U. Vesica formed by a single lobe with microsculpture shown in Fig. 11. Ductus seminis long, in resting position also inversely U­shaped, terminating by strongly sclerotized bulb, bearing apically a wide secondary gonopore with no particular structures framing its broad opening.

Female similar to male, length of body 3.55–3.66 mm, width 1.92 –2.0 mm, length of head 0.46–0.50 mm, width 0.67–0.73 mm, diameter of eye 0.16–0.20 mm. Length of antennal segments in mm: 0.14–0.15: 0.34–0.36: 0.73: 0.19–0.20.

Parieto­vaginal rings ( Figs 12–13 View FIGURES 12 – 14 ) reduced, very small, partially hidden by dorsal wall in dorsal view, their outer margins pointed, the other margins gently curved. Dorso­labiate and ventro­labiate plates undeveloped. Medial plate connecting the sclerotized rings absent. Dorsal wall ( Fig. 12 View FIGURES 12 – 14 ) and anterior sac large, lateral oviducts short and wide. Posterior wall ( Fig. 14 View FIGURES 12 – 14 ) translucent. A structures (inner­ramal sclerites) fused, dorsal margin reinforced, concave, ventral margin straight, lateral margin curved. B structure sensu Chérot (2002) reduced to medial part (the so­called foot or medial process).

Biology

Practically unknown. The specimens were collected by fogging of the forest canopy of Bogani Nani Wartabone National Park (Sulawesi, Indonesia).
