BRIEF DESCRIPTIVE NOTES (after Silvestri [1897b] and Hoffman [in litt.]). Length 32–33 mm, width 4.0– 4.6 mm. Coloration red-grey or brown with a yellowish axial stripe from collum to tip of epiproct, sides, entire epiproct and legs sometimes yellow; metaterga, venter and legs yellowish to brown and reddish-yellow; prozona, except anteriormost ones, sometimes with two whitish paramedian spots; paraterga sometimes yellowish white both dorsally and ventrally. Paraterga broadly and regularly rounded, rimmed throughout, paraterga 2 sometimes with a small lateral tooth towards anterolateral corner; caudal corners increasingly acute from ring 5 on (Fig. 4A). Epiproct short and finger-shaped, with a paramedian pair of small apical claws directed caudoventrallY (Fig. 4C). ♂ legs 3–20 ventrallY with prefemora bearing semi-circular bulges distally and with tibiae carrYing chelae apicallY (Fig. 4B). ♂ coxae 2 enlarged and apicallY truncate; ♂ coxae 3 (Fig. 4B) also enlarged and apicallY truncate, denselY setose, almost in contact mediallY; ♂ coxae 4 and 5 produced ventrad into prominent, blunt, rounded lobes.

Gonopods (Fig. 4D–I) with prefemoral process (PfP) and acropodite (A) subequal in length, both being rather simple, unarmed, with spatuliform apices; PfP strongly twisted; solenomere (sl) simple, helicoid and slender, subflagelliform distallY.

DISTRIBUTION. For C. dOrsAlis: Ecuador, San José, 1°29′03.1″S 80°19′59.7″W [Silvestri, 1897b]. Hoffman [in litt.] elucidated the type locality as actually lying at Rio San José, ca 25 km NW of Gualaquiza.

For C. perprOximA: Ecuador, Valle de Zamora (Santiago Zamora = Zamora Chinchipe), 4°03′44.7″S 78°56′55.7″W [Silvestri, 1897b] .

JUSTIFICATION OF SYNONYMY. Hoffman [in litt.] recorded and depicted ♂ material of this species from Cushuene, Pastaza Prov. (Fig. 4A–E) and Hacienda Santa Inés (1º25′ S 78º12′ W) on Rio Pastaza between Rio Mapoto and Rio Topo, Tungurahua Prov. (Fig. 4F, J), Ecuador, comparing it directly with a syntype of C. perprOximA (Fig. 4G, H). The results unequivocally prove the synonymy and quite a vast distribution of C dOrsAlis (= C. perprOximA, syn.n.) in Ecuador.
