Diagnosis. Females of this new species closely resemble those of P. ecuadoricus sp. n. from the Napo Province of E-Ecuador and the Peruvian J. pachycercus ( Redtenbacher, 1908) . They can however be distinguished from ecuadoricus sp. n. by the broader and more globose head, less pronounced granules of the thorax ( Fig. 33F View FIGURE 33 ), less distinctly granulose abdominal terga, straight posterior margin of the anal segment ( Fig. 34K View FIGURE 34 ; concave in ecuadoricus ), considerably larger and protruding epiproct, less broad subgenital plate which has the apex obtusely pointed ( Figs. 34J–L View FIGURE 34 ), the less deflexed outer ventral carinae of the meso- and metafemora and relatively longer and slenderer tarsi. From the larger and slenderer pachycercus they may also be separated by the head being more globose and relatively larger ( Fig. 33F View FIGURE 33 ) and the subgenital plate notably shorter and obtuse apically (lanceolate, acutely pointed and projecting beyond apex of abdomen by almost combined length of four terminal abdominal terga in pachycercus ). Males resemble those of J. costaricensis sp. n. but can readily be differentiated by the less armed and merely granulose mesonotum ( Fig. 33J View FIGURE 33 ; tubercular in costaricensis ), more densely granulose head and pronotum, plain brown meso- and metafemora (green with only the apex brown in costaricensis ) and distinctive colouration of the mesonotum, which is dark turquoise with a bold brown longitudinal median line ( Fig. 33J View FIGURE 33 ; plain greyish green in costaricensis ).

Etymology. Named after the distribution in Peru.

Description. ♀♀ ( Fig. 32C–D View FIGURE 32 ): Small (body length incl. subgenital plate 96.0 mm) and of average shape for the genus with a large and globose, minutely granulose head, unarmed legs and a moderately long, apically obtuse subgenital plate. The holotype has obviously been preserved in spirits, which has faded the presumably green colour of the life insect to rather plain ochre or dark yellow. Eyes reddish mid brown and the antennae, except for the scapus and pedicellus, with a reddish hue. Granules of the head and thorax yellow. Most of the right antenna and the tip of the left antenna are missing in the holotype.

Head: Large, globose with vertex strongly convex and slightly longer than wide; vertex and genae rather irregularly set with node-like granules of variable sizes (the median ones of the vertex most pronounced). A shallow impression between bases of antennae. The antennae projecting over posterior margin of mesonotum (tips missing). Scapus rectangular in outline and 1.7x longer than wide, pedicellus about 2/3 the length of scapus and round in cross-section; slightly barrel-shaped. Antennomere III somewhat longer than pedicellus, IV less than ¼ the length of III and the proceeding ones gradually increasingly elongated.

Thorax: Pronotum shorter and considerably narrower than head, basically rectangular in shape and somewhat narrowed medially; about 1.4x longer than wide. Surface unevenly granulose and the transverse median sulcus distinctly impressed, very weakly curved and expanding over entire width of segment. Mesothorax elongate, 5.4x longer than pronotum, slightly constricted anteriorly and somewhat widened pre-medially and more notably widened posteriorly; entire surface unevenly covered with node-like to tuberculiform granules. Posterior margin of mesonotum very weakly bulging. Metanotum notably narrowed towards the posterior and 1.5x longer than width of anterior margin; surface of metathorax like mesonotum but granules comparatively smaller.

Abdomen: Median segment 1.2x longer than metanotum and in dorsal aspect with lateral margins concave; surface granulose. Abdominal terga sparsely and minutely granulose but the granulae becoming increasingly sparse and minute towards apex of abdomen. Segment II about 0.8x the length of median segment and slightly narrowed just behind anterior margin. III and IV equal in length and slightly longer than III, VI–VII decreasing in length and width; IV 1.9x longer than wide. Sterna II–VII very sparsely and minutely granulose. Praeopercular organ indistinct and merely represented by two shallow transverse impressions at posterior margin of sternum VII. Terga VIII–X uniform in width, together some 1.3x longer than VII and somewhat narrower than all preceding segments. IX two-thirds the length of VIII. Anal segment rectangular in dorsal aspect with the posterior margin straight and the posterolateral angles broadly rounded; with a fine medio-longitudinal carina dorsally. Epiproct fairly distinct, almost semi-circular, shield-shaped and with a faint medio-dorsal carina; projecting distinctly beyond anal segment. Cerci conical with an acute tip and projecting by about one-third the length of anal segment. Gonapophyses strongly upcurved and protruding over apex of abdomen by almost the length on anal segment. Subgenital plate long, moderately slender, gently upcurved in lateral aspect and with the apical portion gradually tapering towards a narrow tip; extending beyond apex of abdomen by almost the combined length of three terminal terga.

Legs: Rather slender for the genus, the profemora somewhat shorter than mesothorax, the metafemora reaching about one-third the way along abdominal segment IV and the metatarsi reaching abdominal segment VIII. All entirely unarmed. Two outer ventral carinae of the meso- and metafemora weakly deflexed and rounded basally. Tarsi elongate and basitarsi ± as long as remaining tarsomeres excluding the ungues combined.

♂♂ ( Fig. 32D View FIGURE 32 ). Unfortunately, the unique ♂ in MNHN is very incomplete but the morphology of the head, thoracic segments and the locality suggest that it almost certainly is the opposite sex of the ♀ holotype in the collection of ANSP. The specimen lacks the abdomen except for the five basal segments and both front legs.

Of average size and rather stocky for the genus, with a granulose head, densely granulose mesothorax, unarmed legs and distinctive colouration. Basic colour drab, the abdomen with more reddish tones and the head with a slight ochre tinge. Mesonotum dark turquoise with a washed ochreous brown medio-longitudinal streak and the posterior portion of a similar colour. Meso- and metapleurae dull reddish. Mesosternum greyish turquoise anterior and gradually becoming mid green; the metasternum green anteriorly, gradually becoming bright apple green towards the posterior and with a faint yellow medio-longitudinal line. Granules of mesonotum dark green, those of the thoracic pleurae and sterna with a greyish tinge. Tegmina brown with the anterior margin broadly pale cream; costal region of alae green with dark brown longitudinal veins. Coxae brown with ventral surface black. Legs plain mid brown with a slight reddish wash and the carinae of the femora green; apical portion of femora and tibiae very slightly darker brown. Scapus and pedicellus coloured like head, the dark grey and gradually turning to dark reddish brown towards the apex.

Head ( Fig. 33J View FIGURE 33 ): Basically, as in ♀♀ but relatively smaller and somewhat less globose; granules very small. Frons with a pair of shallowly raised and darker brown areas. Antennae fairly thickened and reaching to posterior margin of abdominal segment IV, otherwise as in ♀♀.

Thorax ( Figs. 33J View FIGURE 33 , 84J View FIGURE 84 ): Pronotum generally as in ♀♀ but slightly widened anteriorly and the granules less pronounced. Mesothorax moderately elongate, uniform in diameter with only the posterior portion slightly widened and 4.25x longer than pronotum; complete surface unevenly set with node-like granules. Metanotum all over set with the same granules seen on mesothorax. Tegmina oval in outline with the central protuberance obtusely conical and fairly distinct. Alae reaching half way along abdominal segment VI.

Abdomen: Segments II–V roughly equal in length and uniform in diameter, 3.8x longer than wide. Sterna minutely granulose.

Legs: Mid and hind legs rather stocky but completely unarmed with all carinae of the femora, including the well pronounced medioventral carina, minutely granulose. Basitarsi as long as remaining tarsomeres combined.

Differentiation. Most similar in most morphological aspects and apparently closely related to Globocalynda Zompro, 2001 , with which it shares the short median segment (roughly half as long as the metanotum), and conspicuously enlarged, paddle-shaped gonoplacs of ♀♀, large and apically protruded poculum and long, apically hooked and downward-directed cerci of ♂♂. In Laciphorus however, the head of both sexes is notably more elongate than in Globocalynda , sub-cylindrical in shape with the vertex flattened ( Figs. 35G–J View FIGURE 35 ; ovoid to globose in Globocalynda ) and on average the only known species is smaller than all known members of Globocalynda (body lengths: ♂♂ <68.0 mm, ♀♀ including subgenital plate <103.0 mm). The gonoplacs of ♀♀ are much more enlarged in Laciphorus and may project beyond the tip of the abdomen by almost the length of the anal segment ( Fig. 35C View FIGURE 35 ) and the mesonotum and mesopleurae are all over covered with prominent tubercles ( Figs. 35H–J View FIGURE 35 ). Although the genital morphology of ♂♂ strongly resembles that of Globocalynda , the anal segment is much more tectate longitudinally with the ventrolateral angles protruded into a conspicuous digitiform downward directed process ( Figs. 35D–F View FIGURE 35 ; strongly descendant towards the posterior and mostly without such processes in Globocalynda ), the cerci are notably longer than the anal segment and the poculum bears a distinct spiniform central protrusion in Laciphorus ( Fig. 35D View FIGURE 35 ). The eggs differ from those of Globocalynda by the strongly laterally compressed almost lens-shaped capsule and much slenderer and relatively longer micropylar plate.

Comments. A detailed re-description of this monotypic genus and the type-species were presented by Hennemann & Conle (2020a) along with illustrations and clarification of all synonymies.Since this recent description is sufficient, it is not repeated at this place.

Distribution ( Fig. 103A View FIGURE 103 ). Peculiar the “Coastal Lomas” of western Peru, which biogeographically lie within the Coastal Peruvian Dessert, part of the South American transition zone ( Morrone, 2006: 473, fig. 2).
