Diagnosis. Similar to P. venezuelica sp. n. but differing by: the slightly smaller dimensions; shorter median segment which is shorter than the metanotum (longer than the metanotum in venezuelica ); presence of small apical spines on the medioventral carina of the meso- and metafemora and shorter, more globose head of both sexes. Females ( Fig. 70D View FIGURE 70 ) furthermore differ by the presence of cephalic tubercles or horns in the anterior portion of the vertex ( Figs. 72F–G View FIGURE 72 ; unarmed in venezuelica ), spinose meso- and metasternum ( Fig. 87F View FIGURE 87 ); smaller lobes of the praeopercular organ ( Fig. 91H View FIGURE 91 ) and relatively longer subgenital plate ( Figs. 74D–G View FIGURE 74 ; in venezuelica at best extending beyond apex of abdomen by length of anal segment). Males ( Fig. 70E View FIGURE 70 ) may also be distinguished from those of venezuelica by the different colouration, narrower and rounded instead of triangular lateral lobes of abdominal tergum IX ( Fig. 76A View FIGURE 76 ), less elongate and relatively broader and apically bi-spinose vomer ( Fig. 96C View FIGURE 96 ) and presence of two conical humps on the posterior margin of the poculum ( Figs. 76A View FIGURE 76 , 96C View FIGURE 96 ). The eggs ( Fig. 100N View FIGURE 100 ) differ from those of venezuelica by the much smaller size and conspicuous fimbriate appendages of the capsule. Females also strongly resemble those of P. submutica ( Redtenbacher, 1908) comb. n. in most morphological aspects but may be separated by the more globose head, which has the cephalad horns much more pronounced, slightly longer median segment (only 0.75x length of metanotum in submutica ), more distinct and numerous spines of the meso- and metapleurae and sterna, less emarginate posterior margin of the anal segment, and having the praeopercular organ formed by two longitudinal ridges near posterior margin of abdominal sternum VII (one transverse ridge in submutica ).
Description. Since the original type specimens of Westwood’s turgida are very incomplete re-descriptions of both sexes appear desirable at this place and are presented below.
♀♀ ( Fig. 70D View FIGURE 70 ): Medium-sized (body length including subgenital plate 113.0–155.0 mm), fairly stocky for the genus with a median segment that is slightly shorter than the metanotum, tubercular to spinose meso- and metapleurae and meso- and metasternum, and a subgenital plate that projects beyond the apex of the abdomen by more than the length of anal segment. Body surface mostly smooth. Colour variable and ranging from green over straw, ochre and various shades of brown to dark blackish brown; thoracic armature ochre with dark red points. Base of profemora pale red interiorly. Antennae drab with the scapus and pedicellus coloured like head and the ventral surface distinctly black basally.
Head ( Figs. 72F–G View FIGURE 72 ): Globose, about 1.2x longer than wide, widest at the eyes and distinctly narrowing towards the posterior. Vertex fairly flattened with a slightly impressed coronal line and behind the eyes armed with a pair of obtusely conical humps or anteriad directed spines; the posterior portion occasionally supplied with a few minute granules. Frons with a very distinct, oval transverse impression between bases of antennae and area in frotn of the cephalic horns transversely impressed. Eyes fairly prominent, circular in outline and projecting almost hemispherical, their diameter contained 2x in length of genae. Antennae roughly reaching to posterior margin of abdominal segment III. Scapus strongly compressed dorsoventrally and carinate laterally, rectangular in dorsal aspect and about 1.5x longer than wide. Pedicellus round in cross-section, weakly narrowing towards the apex and about three-fifth the length of scapus. III notably longer than pedicellus.
Thorax: Pronotum slightly longer but notably narrower than head, basically rectangular with the anterior margin concave and slightly widened, the posterior portion narrowing and the posterior margin rounded; a slight constriction pre-medially ( Figs. 72 View FIGURE 72 F-G). An impression near each anterolateral angle and the transverse median sulcus distinctly impressed, gently curved and almost expanding over entire width of segment; median line slightly impressed. Mesothorax very weakly narrowed anterior and with the posterior margin somewhat widened, otherwise uniform in diameter and 6.6x longer than prothorax. Mesonotum with a weak medio-longitudinal carina, which is most pronounced in anterior portion; the anterior portion also granulose but rest of surface smooth and only a fine longitudinal lateral carina present that is roughly parallel to lateral margins. Metanotum smooth with a weakly indicated medio-longitudinal carina, slightly more than one-third the length of mesonotum, rectangular and 2.5x longer than wide. Meso- and metapleurae set with a variable number of spiniform tubercles to spines that are arranged in a longitudinal row, and with a longitudinal row of granules close to lower margin ( Figs. 72F–G View FIGURE 72 , 87F View FIGURE 87 ). Meso- and metasternum unevenly set with spiniform tubercles or spines ( Fig. 87F View FIGURE 87 ), which are less numerous on metasternum.
Abdomen: Median segment about 0.8x the length of metanotum, 2.2x longer than wide and with lateral margins gently concave. Segment II slightly shorter than median segment, II–V slightly gradually increasing and VI–VII decreasing in length with V longest and about 2.2x longer than wide and II shortest and only 1.6x longer than wide: II–IV weakly increasing in width and VI–VI narrowing with VII notably narrower than all preceding. Terga II–VII with a fine and granulose longitudinal median carina and the terminal terga sparsely supplied with some minute, irregularly dispersed granules. Sterna all with a fairly acute and lamellate lateral carina and also supplied with a few minute granules. Praeopercular organ formed by two short raised ridges near posterior margin of sternum VII ( Fig. 91H View FIGURE 91 ). Tergum VIII a little less than half the length of VII, trapezoidal with posterior margin somewhat wider than anterior margin. IX shorter and weakly narrowing towards the posterior, about as wide as long. Anal segment narrower than two preceding terga, scarcely longer than wide and almost rectangular in dorsal aspect; dorsal surface with a fine medio-longitudinal carina and posterior margin weakly emarginated with the outer lateral angles somewhat deflexed and obtusely angular. Epiproct minute and almost fully concealed by anal segment. Cerci small, conical and round in cross-section. Gonapophyses VIII elongate, slender, gently upcurved at the apex and projecting beyond tip of abdomen by no more than length of anal segment ( Figs. 74D–E View FIGURE 74 ). Subgenital plate narrowly naviculate, almost parallel-sided in dorsal aspect ( Fig. 74E View FIGURE 74 ) with the apex rounded and with two prominent, lamellate longitudinal carinae in basal portion; length very variable and projecting beyond apex of abdomen by at least the length of anal segment and at most by the combined length of terminal three terga ( Figs. 74D–G View FIGURE 74 ).
Legs: Moderately long and slender, profemora shorter than mesothorax, mesofemora about as long as metathorax, metafemora reaching about two-thirds the way along abdominal segment IV and metatibiae reaching to abdominal segment VII. Meso- and metafemora with 3–5 blunt apical spines on medio-ventral carina and occasionally with a rounded deflexion or obtuse tooth one-quarter off the base on the two outer ventral carinae; otherwise unarmed. Basitarsi slender with dorsal carina uniform in height and slightly longer than following three tarsomeres combined.
♂♂ ( Fig. 70E View FIGURE 70 ): Of moderate size (body length 76.2–95.0 mm) and averagely stocky for the genus, apterous, with a multi-coloroured thorax, median segment that is slightly shorter than the metanotum, and a vomer with two terminal hooks. Body surface entirely smooth. General colour of the reddish ochre, the abdomen greyish. Head and pronotum drab. Meso- and metanotum orange with the lateral portion green and the lateral margins black. Front legs ochre, meso- and metafemora pale green with the apical portion chestnut brown, the meso- and metatibiae ochre with two faint green annulae. Interior surface of profemora pale to bright red. Eyes reddish mid brown. Antennae dark brown and gradually becoming lighter towards the apex, the ventral surface with a slight reddish wash; scapus and pedicellus drab. The captive reared specimens in the authors collections differ in colouration from most of the other specimens examined by the following points: Mesonotum with a broad longitudinal green band on lateral surfaces leaving just a fine reddish dorso-median line; meso- and metapleurae green except for brown posterior portion which is brown; meso- and metasternum reddish; median segment green in anterior half; base of meso- and metafemora green.
Head ( Fig. 73F View FIGURE 73 ): Globose, about 1.2x longer than wide, broadest at the eyes and distinctly narrowing towards the posterior. Vertex very gently rounded, with a pair of distant conical tubercles just behind the eyes and a pair of much smaller tubercles medially; the posterior portion supplied with a few minute granules. Frons with a very distinct, oval transverse impression between bases of antennae. Eyes prominent, projecting more than hemispherical and their diameter contained only 1.2x in length of genae. Antennae reaching about half way along abdominal tergum V; otherwise generally as in ♀♀.
Thorax: Pronotum basically as in ♀♀. A pit near each anterolateral angle and the transverse median sulcus moderate, straight and expanding almost over entire width of segment ( Fig. 73F View FIGURE 73 ); median line distinct and slightly impressed. Mesothorax uniform in diameter and 7.2x longer than pronotum; medio-longitudinal line of mesonotum very weakly indicated. Metanotum 0.4x length of mesonotum and about 6x longer than wide. Meso- and metasternum with an indistinct medio-longitudinal carina ( Fig. 87G View FIGURE 87 ).
Abdomen: Median segment a little less than two-thirds the length of metanotum and about 5x longer than wide. II slightly shorter than median segment and very slightly longer than II–V; the latter segment roughly uniform in length. VI–VII somewhat decreasing in length. II–VII uniform in width. II almost 4.8x and VII a little more than 4x longer than wide. Tergum VIII trapezoidal and notably widened towards the posterior; slightly more than half the length of VII. IX widest segment, somewhat longer than VIII and more than 2x width of II–VII; lateral surfaces with a longitudinal furrow in posterior half, the lateral margins weakly deflexed and somewhat angular in outline sub-posteriorly. Anal segment notably shorter than IX, the basal half slightly widening, the lateral margins rounded in dorsal aspect and the posterior margin somewhat labiate and broadly bilobate with a shallow triangular median indention ( Fig. 76B View FIGURE 76 ); ventral surface of posterior margin with a few dark red denticles at the outer corners ( Fig. 76C View FIGURE 76 ). Epiproct very small, rounded and slightly projecting beyond posterior margin of anal segment. Vomer broad, weakly narrowing and with a broad apex that is protruded into two equally sized upcurved terminal hooks; ventral surface impressed basally ( Fig. 96C View FIGURE 96 ). Cerci small, oval in cross-section and gently arched towards the posterior. Poculum moderately bulgy and obtusely conical in centre, the ventral surface distinct labiate, downcurved and protruded into two conical downward-directed swellings, concavely excavated medially and with two prominent rounded posterolateral impressions; roughly reaching to posterior margin of tergum IX ( Figs. 76A, 76C View FIGURE 76 , 96C View FIGURE 96 ).
Legs: All long, slender and unarmed except for the medioventral carina of the meso- and metafemora, which is granulose basally, tubercular in the median portion of femur with the tubercles gradually increasing in size to form 2–3 (mesofemora) or 6–7 teeth sub-apically. Profemora a little longer than head, pro- and mesothorax combined, mesofemora almost as long as mesothorax, metafemora reaching about one-third the way along abdominal segment VI and metatibiae projecting greatly over apex of abdomen. Basitarsi slender mesobasitarsi slightly shorter, pro- and metabasitarsi a little longer than remaining tarsomeres combined.
Variability. In addition to the colouration and size ♀♀ show considerable variability in the size and size and shape of the cephalic horns and length of the subgenital plate. While captive reared specimens in the two first author’s collections merely have the horns represented by a pair of obtusely conical humps ( Fig. 72F View FIGURE 72 ) they are of moderate size in the paralectotype and strongly developed and acute forward directed spines in most other ♀♀ examined ( Fig. 72G View FIGURE 72 ). The subgenital plate extends no further beyond the apex of the abdomen than by the length of the anal segment in most specimens examined (e. g. Figs. 74D–F View FIGURE 74 ), but some specimens have it increasingly elongate to extend beyond the tip of the abdomen by as much as the combined length of the three terminal abdominal terga ( Fig. 74G View FIGURE 74 ). Variability is also seen in the size and number of spines on the thoracic pleurae and sterna as well as the size and shape of the sub-basal tooth or deflexion on the two outer ventral carinae of the meso- and metafemora, which may even be completely absent in some specimens. The chromatic variability seen in ♂♂ is summarized in the description above.
Egg ( Fig. 100N View FIGURE 100 ). Small, capsule 2x longer than wide and compressed laterally with lateral margins almost parallel to each other; angular in lateral aspect with polar-area flattened, ventral surface weakly concave and dorsal surface somewhat convex. Capsule surface coriaceous and weakly rugose; along anterior and dorso-lateral margins and around polar-area with short, irregularly fimbriate appendages. Outer margin of micropylar plate with a collar of much longer fimbriate, partly feather-like appendages or pinnae, some which have frills. Micropylar plate large, elongate with lateral margins sub-parallel and both ends rounded and covering four-fifths of dorsal egg surface; surface minutely granulose and rather flattened with just a shallow medio-longitudinal bulge. Micropylar cup near the notched posterior end of plate and represented by a small, knob-like swelling. Median line short. Operculum slightly oval and flat and with a hollow, crenulate structure formed by membranous extensions of the outer margin; these extending by about one-third the length of capsule. General colour of capsule brown, the fimbriate appendages greenish cream and the micropylar plate somewhat darker brown than capsule. Opercular extensions straw-coloured.
Measurements [mm]: Overall length 4.3, length 3.0, width 1.5, height 2.2, length of micropylar plate 2.5.
Comments. Westwood (1859: 28) described P. turgida from a ♂ and ♀ which are mounted on the same pin. The ♂ lacks all extremities and the ♀ has only the right mid leg present. Stål (1875: 6) included it in his new genus Bostra and subsequently Kirby (1904: 350) designated Westwood’s turgida as the type-species. Zompro (2001: 200) designated the ♂ as the lectotype and provided illustrations of the egg ( Figs. 78–79 View FIGURE 78 View FIGURE 79 ) and genitalia of both sexes (figs. 8–9).
Culture stock has been imported to Germany in the early 1990’s originating from near Bejuma in the Yaracuy Province of Venezuela and could be maintained in culture for a few generations.Bramble ( Rubus fruticosu s, Rosaceae ) and roses ( Rosa spp. , Rosaceae ) were frequently accepted as alternative food plants but no further information is available on culture conditions, incubation periods of eggs and nymphal development.
