Type material. Holotype: male, Cordillera Del Condor , alto Río Comaina , Puesto de Vigilancia 22 (Falso Paquisha), department of Amazonas, Peru, 4 o 27’S, 78 o 13’W, 21 October–3 November 1987, D. Silva ( MUSM) GoogleMaps . Paratypes: male and two females, same locality ( MUSM) GoogleMaps ; 2 males and 2 females, same locality ( IBSP 71965 View Materials ) GoogleMaps .

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Architis comaina sp. nov. resembles A. tenuis and A. cymatilis by eye size and arrangement ( Carico 1981; fig. 11), the presence of ventral cuspule-like spines on male coxae I ( Fig. 4E View FIGURES 4 ), the prolaterally notched VTA ( Figs 2A View FIGURES 2 , 3A View FIGURES 3 , 7A View FIGURES 7 ) and the basally fused vRTA and dRTA ( Figs 2B View FIGURES 2 , 3B View FIGURES 3 , 7B View FIGURES 7 ). It can be distinguished by larger, ventrally projected vRTA ( Fig. 7B View FIGURES 7 ) and the longer and narrower apex of the cymbium ( Fig. 7A View FIGURES 7 ) of the male pedipalpus. Females are similar to A. ikuruwa by the CD which are encapsulated in epigynal folds ( Fig. 8B View FIGURES 8 ), but can be differentiated by the sinuous border of the LL of the epigynum ( Fig. 7C View FIGURES 7 ) and the sinuous and apically expanded internal epigynal folds ( Fig. 7D View FIGURES 7 ).


Male ( based on holotype from Cordillera Del Condor , Peru)

Carapace reddish-brown, dark brown medially and marginally. Anterior eye row procurved, lateral eyes strongly projected ventrally and almost twice as large as medians. Posterior eyes of similar size. Clypeus cream-coloured, chelicerae reddish-brown. Sternum cream-coloured, with marginal brown spots at the base of coxae. Labium and endites reddish-brown. Pedipalpi and legs reddish-brown, with dark lateral spots. Opisthosoma dark gray dorsally, with gray spots. Venter and sides cream-coloured, with dark spots. Spinnerets reddish-brown. Total length 5.3; carapace 1.8 long, 1.6 wide. Tibia I length 4.2, II 4.2, III 2.8, IV 3.4. Opisthosoma 2.5 long, 1.3 wide. VTA slightly sclerotised apically; conductor wide, directed anteriorly ( Fig. 7A View FIGURES 7 ).
