Figures 7A–D , 11 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 ) . Paratypes : male and two females , same locality ( MUSM ) ; 2 males and 2 females , same locality ( IBSP 71965 ) . 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 ), the prolaterally notched VTA ( Figs 2A , 3A , 7A ) and the basally fused vRTA and dRTA ( Figs 2B , 3B , 7B ). It can be distinguished by larger, ventrally projected vRTA ( Fig. 7B ) and the longer and narrower apex of the cymbium ( Fig. 7A ) of the male pedipalpus. Females are similar to A. ikuruwa by the CD which are encapsulated in epigynal folds ( Fig. 8B ), but can be differentiated by the sinuous border of the LL of the epigynum ( Fig. 7C ) and the sinuous and apically expanded internal epigynal folds ( Fig. 7D ). Description 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 ). Female ( based on paratype ( MUSM ) from Cordillera Del Condor , Peru ) Colouration as male. Total length 4.8; carapace 1.9 long, 1.7 wide. Tibia I length 3.5, II 3.4, III 2.6, IV 3.0. Opisthosoma 2.9 long, 1.7 wide. Epigynum with LL ventrally projected over MF; copulatory openings positioned anteriorly, inside wide lateral atria ( Fig. 7C ). Variation. Males, total length 4.2–5.3, carapace width 1.6. Females, total length 4.5–5.0, carapace width 1.6–1.7. Distribution. Known only from the type locality in northern Peru ( Fig. 11 ).
