Type speciment. Neotype (here designated): ♀ BOLIVIA, La Paz, Prov. Nor Yungas, Yolosa. 16°14.56’S, 67°44.19’W. 1261 m. (labels with 4140 ft) 13-XII-2008. S.M. Clark. (Det. as S. boliviana by O.J. Cadena-Castañeda, 2018) ( BYUC).

Other specimen examined. ♂ BOLIVIA, La Paz, Prov. Nor Yungas, Pacallo. 16.206°S, 67.793°W. 29-IV- 2005, S.M. Clark & R.L. Johnson. (Det. as S. boliviana by O.J. Cadena-Castañeda, 2018) ( BYUC) .

Redescription. Female. Color mostly olive-green with white punctuations and abundant, dark brown, irregular stripes in the pronotum and the legs; post-ocular stripe present, face greenish-white as is the lower half of the lateral lobes of the pronotum. Upper half of the lateral lobes of the pronotum, as are the upper half of the abdominal and thoracic tergites and legs, yellowish brown ( Figs. 22 A,D ). Head, stout and moderately elongated, eyes globose and not very prominent; frontal costa well advanced before the eyes in lateral view; dorsal carina short, anteriorly projecting before the frons, declivous, lateral carinae rising high, evenly divergent in ventral descendent, narrow scutellum ( Fig. 22B,C ). Pronotum, flat, extending a little beyond the hind femora and the abdomen; moderately elevated in the anterior half of the pronotal disc ( Fig. 22D ). Anterior spine basally heavy, acute, only moderately prolonged and decurved, anterior carinae well developed, weakly concave in lateral viewed from above; lateral lobes wider than long, lateral shoulder carina rounded and not very protruding. Tegmina elongated with a medium sized spot. Legs slender and elongate, fore femora with a well-developed sulcation above; no apical spine; mid femora well-developed to elongated, six times longer than wide, internal dorso-apical spine present, hind femora with pre-genicular spine little developed. Abdomen. Subgenital plate broadly and deeply emarginated apically, with a basally broad, with a very small triangulate median lobe and two lateral rounded lobes ( Fig. 22E ). Ovipositor stout, 1.5 times as long as the sub-genital plate; cerci conical and thickened ( Fig. 22F ).

Male. Similar to the female in morphological structure but with a very similar coloration to the males described for S. hamata ( Fig. 23 A–D). Subgenital plate as long as wide, penultimate male sternite with a mid-prolongation ( Fig. 23E ), cerci cylindrical and with a rounded tip ( Fig. 23F ). triangular epiproct with a pointy tip.

Variation. The only variation observed is the difference in coloration between males and females.

Measurements: CFP: 12,6-11,2; PL: 12,09-11,7; PLB: 3,30-2,75; FF: 2,9-2,1; FL: 4,8-4,6; MFL: 3-2,6; MTL: 3,1-2,7; HL: 6,63-5,85; HW: 1,9-1,4; HL: 5,8-5,2.

Distribution. Bolivian Andes piedmont.

Comments. The type species of this species is lost, as it was originally deposited in the Carnegie Museum of Natural History (CMNH), Pittsburgh, Pennsylvania, USA, but a few years ago the Orthoptera type species were exchanged with Lepidoptera type specimens from the Academy of Natural Sciences (ANSP) (Jhon Rawlins pers. comm), when it conceivably could have been misplaced.

Because of the above, it becomes necessary to designate a neotype specimen that can become the port-name of the species, supported by the following reasons (Art. 75 ICZN): 1. In recent visits to ANSP by the Orthopterists Daniela Santos and Marcelo Ribeiro it was not possible to locate the type specimen of S. boliviana . Besides, this specimen is not catalogued in the list of types of ANSP published by Otte (1979) and it is also missing from the lectotype list of Tetrigidae from the CMNH ( Grant, 1957). Specimens could be tracked to 1962 in Grant’s thesis, but from then on it is not known where they are deposited (Arts. 75.3.1., 75.3.4.). 2. Type location of the original type (female) was Bolivia, Santa Cruz, las Juntas. Fortunately, a female from a nearby location and with the same geological horizon could be studied (Arts. 75.3.5, 75.3.6), and thus a female is proposed for the name bearer, as it better fits the short original description (Recommendation 75A ICZN). 3. A detailed description of the neotype according to the general idea of the species identity, separate from other taxa, ensuring the acknowledgement of the designated specimen, and with a consensus in identifications and wide distribution that characterizes the species, procuring that most identifications of the past are correct (Arts. 75.3.2, 75.3.3, 75.3.5; recommendation 75B). 4. The neotype is deposited in BYUC, a collection from a renowned scientific institution, which has appropriate facilities to store and preserve the types and makes them accessible for study (Art. 75.3.7).
