Dupérré, E. Tapia and C. Tapia ( QCAZ). Female paratype, Cotopaxi Province, Otonga Biological Reserve (00.42261°S 79. 5107°W), 2225m, 26.v.2014, hand collected from web, C. Tapia ( QCAZ).

Additional material examined. Ecuador: Cotopaxi Province, Otonga Biological Reserve (00.42261°S 79.5107°W), 2225m, 26.v.2014, 4♀, hand collected from webs, N. Dupérré, E. Tapia and C. Tapia (DTC).

Etymology. The specific epithet is taken from the Kichwa language and represents the combination of two words, “puka” (red) and “chumpi” (brown).

Diagnosis. Females are diagnosed by their uniform red-brown colour ( Fig. 30 View FIGURES 30 – 33 ). From L. longicauda , L.

aequatorialis and L. cousini by the presence of yellowish setae on the carapace ( Fig. 30 View FIGURES 30 – 33 ). Females can be further diagnosed by their elongated and apically tapering spermathecae, with a few elongated vesicles medially ( Figs. 32, 33 View FIGURES 30 – 33 ).

Cephalothorax: Carapace slightly longer than wide, dark reddish-brown, covered with a mix of numerous short black and golden setae, black setae positioned along radiating lines; margin covered with short golden setae; cephalic region elevated, delimited by deep furrow; fovea recurved, deep ( Fig. 30 View FIGURES 30 – 33 ). Chelicerae black, covered with long black setae; promargin with 10 teeth, fang furrow with seven denticles, retromargin without teeth.

Sternum uniformly brown, covered with long, black, erect setae, flat, slightly longer than wide, with three oval to rounded sigilla, weakly rebordered, border light yellow ( Fig. 31 View FIGURES 30 – 33 ). Eyes: eight on a tubercle; AME rounded, separated by half their width; LE-PME oval, LE touching, ALE the largest; PME the smallest, separated by three times their diameter; anterior row straight, posterior row recurved ( Fig. 30 View FIGURES 30 – 33 ). Abdomen: Elongated oval, dorsally dark red-brown covered with short black setae and black erect setae ( Fig. 30 View FIGURES 30 – 33 ); ventrally dark red-brown covered with short black setae.
