Gymnopholus (Niphetoscapha) wichmanni (Heller) 

( Figs. 7–8View FIGURES 5 – 8, 12View FIGURES 9 – 12, 16View FIGURES 13 – 16, 19View FIGURES 17 – 20, 24View FIGURES 21 – 24, 37–38View FIGURES 33 – 38, 41View FIGURE 41)

Rhinoscapha (Niphetoscapha) wichmanni Heller, 1914: 645  (type locality: Hellwig Mountains ). 

Diagnosis. Pronotum nude, weakly punctate, without distinct granules. Elytral intervals 4–6 with longitudinal impression; longitudinal impressions and subapical portion sparsely squamose.

Redescription. Paralectotype, male ( Fig. 7View FIGURES 5 – 8). Length. Total length 25.0 mm; pronotum + elytron 20.0 mm.

Color dull black, portions of head, pronotum and base of elytra greyish due to age related degradation of cuticle; antennal scape and funicle ferruginous; elytra partly with brownish encrustations presumably consisting of algae or lichens, especially in apical half and in basal portion of longitudinal impressions; venter almost nude, with sparse setae.

Head ( Fig. 12View FIGURES 9 – 12) dull, dorsally nude, with sparse coarse punctures, laterally coriaceous, sparsely setose with short recumbent setae; between eyes 1.05 X as wide as vertical diameter of eye. Eyes moderately prominent from outline of head. Gena 1.22 X as long as vertical diameter of eye.

Rostrum ( Fig. 12View FIGURES 9 – 12) 2.54 X longer than wide at base; maximum width in front of antennal insertion 1.46 X width at base. Dorsum with shallow median impression, without dorsolateral furrows; sparsely punctate with coarse punctures, nude, but presumably scales abraded.

Antenna. Funicle + club 1.64 X length of scape; club 3.55 X as long as wide.

Thorax. Pronotum 1.13 X longer than wide; sides gently sinuate, widest in apical half; disc dull, punctulate, with larger interspersed punctures, without wrinkles or denticles, nude; with shallow median impression, most distinct in apical half. Thoracic venter. Metanepisternite anteriorly with white recumbent scales. Mesoventrite granulate-punctate, with long erect setae; metaventrite sparsely denticulate, sparsely setose with suberect setae not concealing surface.

Elytron 4.53 X longer than wide between humeri; at greatest width 1.18 X wider than between humeri; sides subparallel, weakly rounded; surface dull, coriaceous, without transverse wrinkles; medially dorsally flattened, in basal half intervals 4–6 with longitudinal impression; epipleural edge simple, without fringe of setae; apical declivity at suture with blunt knob, further ventrad with pair of sublateral knobs.

Legs. Surface dull, punctulate, with numerous granules, with sparse suberect setae. Femora moderately long; metafemur in repose not reaching elytral apex.

Abdomen. Ventrite 1–2 medially concave, weakly punctate, sparsely setose; ventrite 5 flat, subapically with densely setose patch. Penis ( Fig. 24View FIGURES 21 – 24) with asymmetrical apical tip moderately wide.

Lectotype, female ( Fig. 8View FIGURES 5 – 8). Same as paralectotype except: Length. Total length 29.0 mm; pronotum + elytron 25.0 mm. Color black, without grey areas of degraded cuticle; integument partly covered with brownish scales and encrustations. Head between eyes 1.07 X as wide as vertical diameter of eye. Rostrum ( Fig. 12View FIGURES 9 – 12) 2.56 X longer than wide at base; maximum width in front of antennal insertion 1.44 X width at base. Dorsum with shallow median impression, in basal half with pair of weak dorsolateral furrows; laterally with sparse erect scales, antennal scrobes clothed with scales and brown encrustations. Antenna. Funicle + club 1.63 X length of scape; club 3.15 X as long as wide. Thorax. Pronotum 1.05 X longer than wide. Elytron 4.28 X longer than wide between humeri; at greatest width 1.20 X wider than between humeri; side moderately rounded; surface markedly coriaceous; apex and longitudinal impressions of intervals 4–6 with dense recumbent scales, sparsely interspersed with short erect scales, with brownish encrustations; knobs at apical declivity ( Fig. 19View FIGURES 17 – 20) more distinct, forming horseshoe-shaped swelling. Abdomen. Ventrite 1–2 convex, medially flat; ventrite 5 subglabrous, sparsely setose.

NieuwGuinea, Lorentz 1909-10 [printed], Hellwig Gebergte, 2500 M, XI.09 [handwritten]”, 2) [blue, small, quadrate] “1912 [printed], 6 [handwritten]”, 3) [red, rectangular] “Typus!

Riedel 2014 [printed]”; condition: fair; right antennal club broken and missing; 5 eggs found in abdomen and glued to card; genitalia in glycerol, in microvial attached to pin (SMTD); paralectotype, male: labels ( Fig. 38View FIGURES 33 – 38): 1) [white, rectangular]: “Z. NieuwGuinea, Lorentz 1909-10 [printed], Hellwig Gebergte, 2500 M, XI.09 [handwritten]”, 2) [blue, small, quadrate] “1912 [printed], 6 [handwritten]”, 3) [red, rectangular] “Cotypus [handwritten] “, 4) [white, rectangular] “Staatl.

Riedel 2014 [printed]”; condition: fair; specimen abraded and showing age-related degeneration of cuticle; genitalia glued to card (SMTD).

Distribution ( Fig. 41View FIGURE 41). To date only known from the type specimens. Based on the data from the map given by Nouhuys (1914) and Google Earth the approximate coordinates of the type locality are E 138°43.963´ S 4° 30.952´, about 25 km linear distance south of Mt. Trikora.

Notes. The two syntypes at hand differ somewhat morphologically. Heller (1914) did not mention the total number of specimens, so other syntypes may exist. He marked the female as “type”, the male as “cotype” but he did not mention these terms in the original publication. To ensure stability of nomenclature the female marked by Heller as “type” is here designated as lectotype.
