Etymology. The specific epithet is a patronymic in honor of the late French arachnologist Lucien Berland, for his many contributions to arachnology including the Ecuadorian Anyphaenidae . It is a noun in possessive substantive.

Diagnosis. Males are easily distinguished from other species by the bifid external section of the conductor, with beak-shaped anterior tip, longer than the posterior one, which is sharp and thin, elongated subapical protrusion ( Figs 25A View FIGURE 25 , 26A View FIGURE 26 , 27A–B, D View FIGURE 27 ), median apophysis bifid, laminar, projected, with the anterior tip longer than the posterior one ( Fig. 27B, F, H View FIGURE 27 ), tegulum prolaterobasally projected ( Figs 25A View FIGURE 25 , 26A View FIGURE 26 , 27A View FIGURE 27 ). Females are distinguished by a bilobed median field folded toward the median notch, wide lateral lobes with basally rounded posterior sclerotized projections, and an arch-shaped narrow median notch ( Figs 25E–F View FIGURE 25 ).

Color: carapace dark brown, with cervical groves spotted in black and converging in the large black patch on fovea. Lateral region with two poorly defined dark bands on sides, covered by abundant white setae. Ocular area on a black patch, eyes bordered in black rings. Clypeus brown, low with abundant white setae. Chelicerae brown with black stripes and fine setae on frontal edge. Endites, labium, and sternum brown with some dark spots; labium more pigmented. Legs coxae-tarsi brown, femora with dark longitudinal bands, tibia-metatarsi with rings of white setae; tarsi uniformly brown. Articles with abundant white setae. Abdomen dehydrated, with a pattern of faint light spots on a dark gray background, covered by abundant white setae. Venter uniformly dark gray. Palp: tegulum with very developed median hematodochae ( Figs 25A View FIGURE 25 , 26A View FIGURE 26 , 27A View FIGURE 27 ). Median apophysis very large, bifid, with anterior branch long, laminar, with projected prolateral tip, posterior branch membranous at base and with the external border sub-rounded ( Figs 25A–B View FIGURE 25 , 26A–C View FIGURE 26 , 27A, B, D, F View FIGURE 27 ). Conductor small, rounded, with projected base, external section apically wide and bifid, with a swollen, elongated projection; anterior tip of external section large, curved, and longer than posterior; posterior tip short and sharp; internal section ending as a sharp tip, converging with the posterior tip of external section ( Figs 25A–B View FIGURE 25 , 26A–C View FIGURE 26 , 27A, B, D, F View FIGURE 27 ). Paramedian apophysis large, cup-shaped, heavily sclerotized, concave, apically acuminated ( Fig. 27C, E View FIGURE 27 ) Embolus short, tape-shaped at base, coiled, with poorly developed laminar projection, apically filiform; basal process small, flat, retrolateral region pointed in posterior region, prolateral region oval, poorly pronounced external keel ( Figs 25A–D View FIGURE 25 , 26A–C View FIGURE 26 , 27 View FIGURE 27 ).

Abdomen: length 2.53, width 1.54, spiracle–epigastrium 0.80. Color pattern as in male, but dark brown, abdominal and legs spots more defined. Sternum and labium darker. Epigyne: anterior plate sclerotized with accentuated anterior excavations, median excavation long and narrow ( Figs 25E View FIGURE 25 , 26D View FIGURE 26 ). Median field totally divided in two sub-rounded section interrupted by a large medial depression ( Fig. 28E – F View FIGURE 28 ). Lateral lobes with sclerotized extensions wide, swollen and apically rounded ( Fig. 25E View FIGURE 25 ). Copulatory ducts short joining with the accessory bulb ducts at medial level.
