9. Globocalynda unilobata View in CoL (Brunner v. Wattenwyl, 1907: 330 ) [ Calynda ]. LT [by present designation], ♂: Coll. Br. v. W., Bolivia, Antonio, Staud.; det. Br. v. W., Calynda unilobata ; 22.076 [NHMW, No. 671]; PLT, ♀: Coll. Br. v. W., Bolivia, Antonio, Staud.; det. Br. v. W., Calynda unilobata ; 22.077 [NHMW, No. 671].

= Calynda simplex Brunner View in CoL v. Wattenwyl, 1907: 329 (in part—only PLT’s from Bolivia). PLT, ♂: Coll. Br. v. W., ( Songo ) Bolivia, Staudinger; det. Br. v. W., Calynda simplex Br. View in CoL ; 22.249 [NHMW, No. 669]; PLT, ♀ (+ 2 eggs ex ovipositor): Coll. Br. v. W., (Songo) Bolivia, Staudinger; det. Br. v. W., Calynda simplex Br. View in CoL ; 22.250 [NHMW, No. 669]; PLT, 2 ♂♂: Mapiri, Bolivia, Staudinger; Collectio Br. v. W.; det. Br. v. W., Calynda simplex Br. View in CoL ; 25.613 [NHMW, No. 669].

Remarks: All Bolivian paralectotypes of Calynda simplex are in fact G. unilobata (see above). Already Brunner v. Wattenwyl (1907: 330) stated that the ♂♂ of these two species were impossible to distinguish, which was confirmed by careful examination of the complete type-series. The sub-apical dorsal lobe on the mesofemora of ♀♀ of unilobata , which is the only feature that Brunner v. Wattenwyl provided to distinguish it from simplex , is obviously subject to intraspecific variation in this species. The eggs were briefly characterised and illustrated by Zompro (2001a: 202, figs. 82–83) as “ Globocalynda simplex ”.

Females of this species show considerable variability in size and armature of the mid and hind legs. White the meso- and metafemora are wholly uanarmed (with exception of the dentate sub-apical protrusion on the two outer ventral carinae) in the paralectotype of simplex from Rio Songo, there is a prominent, obtusely triangular sub-apical lobe on the posterodorsal carina of the mesofemora in the paralectotype of unilobata from Antonio. The ♀ from Uyapi in the collection of ANSP and ♀ from the Sara Province in MNHU have this lobe notably more distinct (rounded and almost semi-circular in the Uyapi specimen) and moreover have a small, triangular sub-apical lobe at the same position on the metafemora. In addition to these, there is a large and rounded sub-basal lobe on the two outer ventral carinae of the meso- and metafemora (more pronounced on mesofemora) and also the meso- and metatibiae have a roundly triangular dorsal lobe just before the apex. Measurements in table 7 below.

Distribution: N-Bolivia, Province Cochabamba, Antonio [NHMW]; W-Bolivia, Province La Paz, Mapiri [NHMW]; WBolivia, Province La Paz, Rio Songo [NHMW, MHNG, ZMUH]; W-Bolivia, Province La Paz, Yungas de la Paz, 1000 m [MNHU]; W-Bolivia, Province La Paz, Uyapi, 15°25’S 67°46’W [ANSP]; Bolivia, Province Sara 450 m [MNHU].
