Diagnosis. From the known ♂♂ of the genus, those of P. schulthessi are at once distinguished by the very slender shape and presence of tegmina and well-developed alae, that reach almost to the posterior margin of abdominal segment IV ( Fig. 72E View FIGURE 72 ). The only other known ♂ with wings is that of Venezuelan P. semiptera sp. n., but this species is very different in many aspects, e. g. being much larger (body length 128.5 mm), much stockier in shape, having alae that reach not further than to abdominal tergum III and having a very different colouration, including two black parallel stripes on the mesonotum and bright red interior surfaces of the profemora. Females ( Fig. 72D View FIGURE 72 ) are very similar to those of P. lanceolata Conle et al., 2011 and P. sagitta Conle et al., 2011 but differ from both species by the stockier body and legs and proportionally shorter body segments, longer median segment, that is slightly longer than the metanotum (shorter than metanotum in lanceolata and sagitta ) and trifid praeopercular organ, that has the lateral lobes foliaceous and much larger than in these two species ( Fig. 91J View FIGURE 91 ), as well as the shorter subgenital plate, which at extends beyond the tip of the abdomen by no more than the combined length of the three terminal abdominal terga ( Figs. 73N–O View FIGURE 73 ). From the first the ♀♀ of schulthessi may also be separated by the deeply, triangularly incised and acutely bilobate posterior margin of the anal segment and from the latter by lacking the red bases of the profemora and having the granulations of the thoracic segments much less distinct.
Description. ♂♂ ( Fig. 71D View FIGURE 71 , 127 View FIGURE 127 C-D): Moderately sized (body length 81.0–103.0 mm), very delicate for the genus with well-developed alae (length 30.0– 32.2 mm). General colour green with the abdomen slightly brownish and the legs buff with the meso- and metafemora and tibiae each with three straw-coloured annulae and the front legs rather irregularly annulated. Head with a faint yellow postocular streak and with the anterior angle below the eye or entire lower portion of genae yellow ( Fig. 73D View FIGURE 73 ). A fine yellow line along lateral surfaces of mesonotum and the lateral margin marked by a fine grey to black line. Meso- and metasternum brown ( Fig. 87L View FIGURE 87 ). Tegmina and costal region of alae green with the portion anterior to the radial vein yellow and the anterior margin black. Anal fan of alae hyaline. Pedicellus dull green, rest of antennae black basally and gradually turning mid brown towards the tip. Captive reared specimens with all the green portions of the head, body and wings pale drab and the yellow portions rather cream-coloured.
Head ( Fig. 73D View FIGURE 73 ): Ovoid, broadest at the eyes and strongly narrowing towards the posterior, 1.25x wider than longer than wide and the vertex weakly convex and smooth. Frons with two small pits between bases of antennae and area between the eyes slightly raised. Eyes very large, circular in outline, projecting hemispherical and their diameter contained 1.3x in length of genae. Antennae almost reaching to tip of abdomen. Pedicellus increasingly compressed towards the base with the apex weakly oval in cross-section, rectangular in dorsal aspect and about 1.3x longer than wide. Pedicellus round in cross, section, somewhat constricted at base and about half the length of scapus. III notably longer than pedicellus and with apical half notably narrowed.
Thorax: Pronotum slightly shorter and much narrower than head, basically rectangular in shape with the posterior margin rounded and a weak narrowing pre-medially; 1.6x longer than wide ( Fig. 73D View FIGURE 73 ). Transverse median sulcus moderately distinct, straight and just not reaching to lateral margins of segment; the median line distinctly impressed over its entire length. Mesothorax uniform in diameter and slightly narrower and about 8.3x longer than pronotum. Mesonotum with the median line weakly indicated and a fine, granulose longitudinal lateral carina parallel to lateral margins. Meso- and metasternum with a fine longitudinal median carina, that is fairly acute on mesosternum ( Fig. 87L View FIGURE 87 ) and weakly developed on metasternum. Tegmina elongate-oval, scaphiform, gradually narrowing in the basal portion and with the central protuberance obtusely rounded and moderately developed. Alae on average reaching some three-quarters the way along abdominal tergum IV.
Abdomen: Median segment almost 3x longer than metanotum. Segment II notably shorter than median segment, II–VII uniform in diameter but gradually decreasing in length with II about 5.5x and VII only 4.3x longer than wide. Tergum VII slightly widened at posterior margin and weakly constricted medially. Tergum VIII about two-thirds the length of VII, very weakly widening towards the posterior, about 1.6x longer than wide and with a very prominent tectifirm longitudinal bulge laterally. IX of similar dimensions as VIII and slightly narrowing towards posterior, the lateral margins straight but slightly gradually deflexed towards the posterior and the lateral surfaces with an obtuse longitudinal bulge in basal half ( Fig. 76G–J View FIGURE 76 ). Anal segment somewhat wider than IX, basically rectangular in dorsal aspect but somewhat constricted at anterior margin; the posterior margin weakly concave ( Fig. 76H View FIGURE 76 ) and entire posterior margin unevenly set with small reddish brown denticles ventrally ( Figs. 76J View FIGURE 76 , 96H View FIGURE 96 ). Phallus strongly enlarged, digitiform, sinistral-directed and projecting projecting ( Figs. 76G–J View FIGURE 76 ). Vomer long, very slender, gradually constricted towards a pointed terminal hook and strongly arcuate; basically, almost semi-circular in lateral aspect but the upcurved distal half notably dextrad directed ( Fig. 96H View FIGURE 96 ). Cerci elongate slender, fairly straight and weakly club-shaped. Poculum convex but weakly bulgy and rather scoop-shaped with the posterior margin slightly labiate, rounded and not reaching to posterior of tergum IX ( Fig. 76G View FIGURE 76 ).
Legs: all very long, delicate and entirely unarmed. Profemora notably longer than head, pro- and mesothorax combined, mesofemora longer than pro- and mesothorax combined, metafemora reaching to posterior margin of abdominal segment V and metatibiae projecting greatly over tip of abdomen. Basitarsi long and slender, all notably longer than remaining tarsomeres combined.
Egg ( Fig. 100J View FIGURE 100 ). Fairly large, capsule ovoid with the dorsal surface somewhat more convex than ventral surface and the polar-area slightly flattened; 1.5x longer than wide. Capsule surface minutely coriaceous and all over coarsely and unevenly covered with a network of strongly raised bulges, which are somewhat less pronounced on the lateral surfaces. Micropylar plate pear-shaped with anterior end narrowed. Outer margin raised, the surface generally flat, minutely coriaceous and with an uneven, medio-longitudinal bulge in the posterior two-thirds. Micropylar cup a moderately distinct, node-like swelling at posterior end. Median line short but distinct. Operculum flat, oval and with a high and hollow capitular structure that is formed by membranous, lamellate extensions of the outer margin; this structure somewhat crenulate at the apex and extending by about half the length of capsule. Capsule plain drab with the polar-are slightly greyish, the micropylar plate somewhat darker. Operculur structure dark yellow to orange.
Measurements [mm]: Overall length 4.3–4.8, length 3.0–3.1, width 2.1–2.2, height 2.2–2.4, length of micropylar plate 1.3.
Comments. Gutiérrez & Bacca (2014: 219, fig. 19) recorded this species from the Ñambí River Nature Reserve , Nariño, SW-Colombia and provided an illustration of the previously unknown ♂. A full description of the ♂ is provided above along with a description of the as yet unknown egg. Stock from Pajal, Province Manabí, Ecuador, was imported to Europe in 2008 and breeding in captivity was attempted. The culture could however only be maintained for one generation and nothing hatched from eggs laid by the F1-generation ♀♀. Bramble ( Rubus fruticosus , Rosaceae ) was frequently accepted as an alternative food plant .
