 Type material. Holotype, female: Ecuador: Napo Prov., Res. Ethnica Waorani, 1km S Onkone Gare Camp., Trans. Et., 00°39’10’’S, 76°26’W, 220m elev., October 1994, T.L. Erwin et al. collectors; indiv#002245. Paratype: same data as HT, except indiv#002202 (1). Holotype temporarily held in trust at USNM for MECN, one paratype in QCAZ.   
 Diagnosis. Interstriae 10 sharply elevated to level of ventrite 2. Protibiae with a tiny additional mesal tooth at base of tooth 2. Pronotum lightly asperate on anterior half. Erect interstrial setae and fine strial setae present mainly on declivity. Not very close to other species in the genus, but share some features with S. marginatus Wood, 1969.   
 Description, female. Length 1.4–1.5 mm, 2.4–2.5 × as long as wide; colour brown. Head. Eyes almost entire, a tiny notch at level of antennal insertion, separated above by 1.1–1.2 × their width. Frons lightly impressed between eyes on lower two-thirds, punctures in impressed area large, deep; vestiture consisting of sparse, long setae arising from upper level of eyes, reaching level of antennal insertion, with short, fine setae on epistoma and central part of impressed area. Antennal club pilose with two obliquely procurved sutures, segment 1 and 2 partly corneous. Funiculus 5-segmented. Pronotum strongly reticulate, punctures obscure, not reaching anterior margin, distinct asperities present on anterior half. Vestiture consisting of 8 long, erect setae (4-2-2) and some additional, shorter, erect setae along anterior margin. Elytra smooth, shiny; striae regular, striae 1 weakly impressed, others not, punctures shallow in striae 1 slightly larger than other striae, spaced by 1–2 × their diameter; interstrial punctures microscopic, widely spaced. Interstriae 10 sharply raised to level of ventrite 2. Vestiture consisting of erect, spatulate, interstrial setae and much finer, semirecumbent strial setae, mainly on declivity. Legs. Procoxae separated by 0.3 × the width of one procoxa. Mesocoxae separated by 0.7 × the width of a procoxa. Protibiae narrow, distal teeth 1 similar to 2, with 4–5 lateral, tiny granules towards tibial base; a tiny additional mesal tooth present on posterior face at base of tooth 2; protibial mucro obtuse. Meso- and metatibiae with 6 and 5 socketed teeth on distal half and one-third, respectively. Ventral vestiture. Setae on mesanepisternum and metanepisternum bifid or trifid, on metasternum bifid or simple.   
 Male. Not known.   
 Key (Wood 2007). Keys to couplet 91 or 92, near S. glabratus (Schedl), but is overall more similar to S. marginatus (couplet 94). The new species differs from all others by the distinct pattern of setae on the declivity.   
 Etymology. The Latin name cnesinoides is composed by the stem of the genus name Cnesinus LeConte, 1868 and the Latin or ancient Greek suffix - oides, meaning resembling, referring to the superficial resemblance to species in the genus Cnesinus, e.g. C. exellens Wood, 2007.   
 Biology and distribution. Only known from a single canopy fogging collecting event in the Amazonian lowlands of Ecuador.
