Types. Holotype: Ƌ, Bolivia – Region Chapare – 400 m – leg. Zischka 2. XI. 54 ( ZSMC) . – Paratype: 1Ƌ, Bolivia trop., Prov. Chapare, 400 m, leg. 15. XI. 1949 Zischka ( ZSMC) .

Differentiatial diagnosis. Closely related to J.pachycercus (Redtenbacher) from Peru, but distinguished by: the distinctly larger size; shorter and more globose head; smooth and glabrous bluish green mesonotum and mesopleurae, the first having a fine, longitudinal, black median line; and relatively shorter alae which do not exceed the posterior margin of tergite IV. From J. guianensis , spec. nov. from French Guiana it differs by: the shorter and more globose head; relatively longer mesothorax; smooth and glabrous bluish green mesonotum and mesopleurae, the first of which has a fine, longitudinal, black median line; shorter tergite IX; shorter alae which do not reach tergite V and reddish brown instead of green tibiae.

Description

The PT appears to have been a just newly adult specimen when it was captured and has the typical colouration, especially of the mesothorax, less developed than the HT.

ƋƋ: Medium sized (body length 75.0-75. 8 mm), slender (maximum body width 2.5 mm) species with long, slender legs and shortened alae (24.2-24.4 mm). Head, prothorax, metasternum and abdomen plain yellowish or mid brown. The HT has the head with two very faint oval dark markings and another very faint dark marking close to lateral margin. Lateral margins of pronotum black. Mesonotum glabrous pale bluish green (greyish in the PT) with a very fine, black longitudinal median line and a slightly broader, dark brown longitudinal line about 0.5 mm off the lateral margins, each of which gradually widens to a broad dark brown marking in posterior section of mesonotum; these markings melted with another. Lateral margins of mesonotum marked by a distinct black line. Mesopleurae pale blueish green, posterior margin black. Mesosternum only blueish green in anterior section but soon becoming dark brown and with the median longitudinal keel black. Metapleurae greenish brown. Abdominal tergite IX with a pale anterolateral marking. Tegmina plain mid brown with anterior margin straw.Costal region of alae pale to mid brown with a bold rounded patch at the base, a slightly paler anterior margin and all longitudinal veins dark brown. Anal region very slightly brownish, transparent and with the veins brown.Ventral surfaces of all coxae black. Meso- and metafemora green to gryish green; all femora with apex black. Profemora and all tibiae and tarsi orange to reddish brown; apices of tibiae brown (HT) or black (PT). Antennae dark brown and almost black ventrally.

Head. Oval, subcylindrical, 2 × longer than wide, broadest slightly behind the eyes, smooth; vertex gently rounded. Between bases of the antennae with a distinct impression and a minute granule at the anterior margin of the head capsule. Between the eyes with two oval, very slightly raised areas. Eyes circular, strongly convex, projecting hemispherically. Antennae long, filiform and reaching to posterior margin of abdominal tergite VIII. Scapus oval in cross-section, 1.5 × longer than wide, parallel-sided. Pedicellus cylindrical, 2 / 3 the length of scapus.

Antennomere III slightly longer than pedicellus but distinctly narrower. IV less than half the length of III.Following antennomeres increasing to about mid if antennae, then decreasing in length.

Thorax. Pronotum slightly shorter and considerably narrower than head, almost 2 × longer than wide and parallel-sided with anterior margin broadened. Lateral margins raised, transverse median depression very slightly curved and anterior half with an impressed median line. Otherwise smooth except for a very few minute granules. Mesothorax elongate, 2.2 × longer head and pronotum combined, slightly narrower than pronotum and of constant width except for being slightly widened at the posterior.Mesonotum with a very faint and lightly raised longitudinal median carina and and with a few minute, black granules; otherwise smooth. Mesopleurae with a longitudinal row of minute, black granules. Mesosternum with a distinct longitudinal median keel. Metanotum broader than mesonotum, 1.5 × longer than wide. Metapleurae and metasternum with a faint longitudinal median carina. Tegmina elongate, oval, narrowed towards the base and with a small, conical central hump; slightly projecting over posterior margin of metanotum. Alae reaching half way along tergite IV.

Abdomen. Median segment 2.5 × longer than metanotum, smooth, parallel-sided. Segments II-V of equal length, 4 × longer than wide and parallel-sided. VII and VII slightly shorter; VII slightly broadened at posterior margin. Tergites smooth except for a very minute granules which can only bee seen at 4 × magnification. Sternites II-VII with distinct, longitudinal median keel. Tergite VIII less than 2 / 3 the length of VII and strongly widened towards the posterior. IX 3 / 4 the length of VII strongly convex and prominently medially constricted. Anal segment half the length of IX but broader, transverse, laterally rounded and with a broad medial indention at posterioer margin. Cerci 2 / 3 the length of anal segment, very prominent, dorsoventrally flattened with apices truncate, angled inwards and strongly broadened. Vomer very elongate, gradually pointed towards a pointed tip which almost reaches the posterior margin of the anal segment, lateral margins raised. Subgenital plate convex, cup-like, slightly projecting over posterior margin of tergite IX and with two small medial teeth at posterior margin.

Legs. All long, rather slender and destitute of spines or teeth. Profemora longer than mesothorax, mesofemora about as long as mesothorax and hind legs projecting over apex of abdomen. Medioventral carina of femora distinct. Pro- and mesobasitarsus 1.5 × longer, metabasitarsus 2 × longer than remaining tarsomeres combined.

Etymology. The specific name “ bolioianus ” refers to the type-locality Bolivia.
