HT, ♂: Marcapata, Peru, Staudinger; Collectio Br. v. W.; det. Br. v. W., Calynda simplex Br. ; 24. 150; Paralectotypus (PLT of Calynda simplex Brunner v. Wattenwyl, 1907: 330 ) [NHMW, No. 669].

PT, ♂: Peru, 500 m, Ob Madre de Dios, Garlepp V. [ MNHU] .

Diagnosis. Males of this new species (the only sex known) are very similar to G. simplex (Brunner v. Wattenwyl, 1907 ) and G. unilobata (Brunner v. Wattenwyl, 1907 ) but at once differ from those of both species by the very distinct colouration. In contrast to these two species, the mesothorax is brown with only the extreme posterior portion as well as the head and pronotum bluish green Fig. 20E View FIGURE 20 ; (vice versa in simplex and unilobata ). From G. simplex they also differ by the smaller size, plain reddish brown meso- and metafemora (bases of all femora green in simplex ), less fornicate poculum ( Fig. 23L View FIGURE 23 ) and differently shaped anal segment. From G. unilobata they may also be separated by the slightly slenderer body, less distinct transverse posterior black stripes of the abdominal terga, not distinctly and broadly black apices of the femora, less fornicate poculum ( Fig. 23L View FIGURE 23 ) and very different shape of the anal segment.

Etymology. Named after the Cordillera de Marcapata in western Peru, the type-locality of this new species.

Description. ♂♂ ( Fig. 20E View FIGURE 20 ): Of moderate size (body length 70.0–80.0 mm) and fairly slender for the genus with a characteristic colouration. Great parts of mesothorax orange-brown (holotype) to dark red (paratype), the abdomen dark ochre with the three terminal segments dark brown. Extreme anterior portion and posterior portion of mesothorax and most of metathorax pale greyish blue (holotype) or bluish green (paratype), head and pronotum very dull green (with a slight greyish wash in the holotype). Posterior margin of body segments with a distinct black transverse band, abdominal tergum VIII with an ochre marking laterally. Legs reddish pale brown with the apex of all femora black (basal portion dark greenish in the paratype) and the base of the profemora turquoise. Eyes ochre, antennae black with the apex brown.

Head ( Fig. 21L View FIGURE 21 ): Elongate-ovoid, about 1.3x longer than wide, broadest at the eyes, narrowing towards the posterior with vertex flat and smooth except for a slightly impressed coronal line. Eyes prominent and strongly projecting, slightly oval in outline and their length contained about 1.6x in length of genae. Antennae reaching to posterior of abdominal tergum VII. Scapus weakly compressed dorsoventrally, oval in cross-section, roundly rectangular in dorsal aspect and about 1.4x longer than wide. Pedicellus round in cross-section and somewhat shorter than scapus. III notably longer than pedicellus and slightly narrowing towards the apex.

Thorax: Pronotum slightly shorter but noticeably narrower than head, roughly 1.3x longer than wide and distinctly narrowed medially with the lateral margins strongly concave. Medio-longitudinal line notably impressed over whole length. Transverse median sulcus distinctly impressed, gently curved and almost expanding over entire width of segment. Mesothorax narrower than prothorax and about 8.5x longer than prothorax, uniform in diameter except for a slight widening at the anterior margin and in posterior portion. Metanotum slightly less than half the length of mesonotum; both with a very weakly indicated medio-longitudinal line and a row of minute granules laterally. Meso- and metasternum with a distinct carina medio-longitudinally

Abdomen: Median segment a little less than one-third the length of metanotum, about 2.7x longer than wide and slightly widening towards the posterior with the lateral margins weakly concave. Segment II about 1.25x longer than median segment, II–V increasing and VI–VII decreasing in length with II about 3.3x and V 4x longer than wide; VII only two-thirds the length of V. All terga with an obtuse longitudinal bulge parallel to lateral margins; otherwise these segments wholly smooth. Terga VIII–X taken together scarcely longer than VII and considerably broader than all preceding segments. VIII about two-fifth the length of VII narrowed in anterior portion and in posterior portion strongly widened with the posterior margin almost 2x broader than anterior margin; the posterior portion somewhat gibbose and the lateral surfaces with a distinct, obtuse longitudinal bulge. IX longer than VIII and roundly rectangular in dorsal aspect with the lateral margins weakly deflexed towards the posterior; strongly gibbose in the posterior portion, which is about 1.5x higher than the anterior portion. Anal segment only about half the length of IX, strongly descendant towards the posterior and triangular in lateral aspect ( Fig. 23L View FIGURE 23 ), slightly wider than long and with an obtuse medio-longitudinal dorsal bulge; shape trapezoidal in dorsal aspect with the posterior margin narrowly and roundly emarginated medially and the outer lateral angles protruded into an obtusely rounded, almost hemispherical swelling ( Fig. 23M View FIGURE 23 ). Ventral surface of the posterolateral swellings set with several minute dark reddish brown teeth. Vomer basically triangular with a short but pointed terminal hook. Cerci elongate with the apex slightly club-like and a little longer than anal segment ( Fig. 23M View FIGURE 23 ). Poculum very bulgy, roundly cup-shaped and very scarcely higher than tergum IX with the posterior half carinate medio-longitudinally; posterior margin somewhat protruded, with a narrow median incision and almost reaching to apex of anal segment ( Fig. 23M View FIGURE 23 ).

Legs:All long, slender and wholly unarmed. Profemora a little longer than head, pro- and mesonotum combined, mesofemora almost as long as mesothorax, metafemora reaching about one-third along abdominal segment VI and metatibiae greatly projecting beyond apex of abdomen. Basitarsi slender and very elongate, mesobasitarsi about 1.3x, pro- and metabasitarsi about 1.5x longer than remaining tarsomeres taken together.

Comments. The holotype of this new species is one of Brunner v. Wattenwyl’s syntypes of Calynda simplex . It is surprising that the strikingly different colouration was not recognised by Brunner nor by Zompro (2001a: 202), who selected the ♂ from Callanga, South-Peru in the collection of NHMW as the lectotype of C. simplex . In addition to that the colouration differs from all other paralectotypes at first glance, the holotype of G. marcapatae sp. n. is from a different quite separate locality in western Peru and also differs from the lectotype of simplex by the notably smaller size (see table 7 below) and morphology of the genitalia ( Figs. 23L–M View FIGURE 23 ). Females and eggs unknown.
