 Etymology: Named after Mr Nicholas Locke, who continuously struggles for the integrity of the REGUA natural reserve.   
 Diagnosis: Similar to P. modestus in the skirt being acorn-shaped, greatly folded (as a tricorn fan or parabolic erect in the other species). Similar to P. colatinae in the scutal groove II being straight (arched frontwards in all other species). Separated from all other species by the ocularium being wide and very high (instead of ordinary ovoid) and the acuminate tubercles on scutal areas II to IV. Tarsal counts slightly higher than most Paratricommatus – Ta II, IV higher than pentamerous. Patella II not particularly elongate (as in P. modestus); pedipalpus of male not massive (as in Gen. sp. H); stylus C-shaped (instead of substraight in P. modestus). Basichelicerite sturdy (instead of elongate slender as in P. mahnerti and sp. H).   
 Description, male holotype: Dorsum. Dorsal scutum subrectangular with constrictions well marked and coda wide (Figs 18B, 19A). Carapace slightly convex and projected anterolaterally and almost as long as abdominal scutum. Frontal hump strongly developed, unarmed (Fig. 18A). Ocularium located far from the anterior margin of scutum, very wide and high, armed with a single median sturdy spine (Fig. 18D). Mesotergum divided into four areas separated by straight grooves. Area I entire. Scutal areas II to IV armed with slightly asymmetrical paramedian acuminate tubercles (Fig. 18A, B). All scutum finely granular with a transverse row of setiferous tubercle on each of the free tergites. Ozopore single. Venter (Fig. 19E). Stigmatic area short, partly fused with coxae IV. Coxa IV armed with proventral apical spiniform apophysis matching lobe on sternite II. Chelicera (Fig. 20A, E). Basichelicerite short, with well-developed bulla. Hand not swollen. Pedipalpus (Fig. 20B). Without particularly elongate or incrassate articles. Trochanter armed with dorsal protuberance and two ventral setiferous tubercles. Femur slightly compressed and slightly convex dorsally, with a ventral row of three small, setiferous tubercles on proximal half. Tibia and tarsus with the usual armature of setiferous tubercles – tibia ectal with III, mesal with IiIi, tarsus ectal and mesal with IiIi. Legs (Fig. 20C–E). Legs short, without armature, except for ventral row of setiferous tubercles on femur I. Femur IV sinuous, unarmed. Tarsal counts 4(3)/6(3)/5/6. Genitalia. Distal part of truncus shaped as an oblique kidney-shaped malleus and an erect LP. Malleus with one pair of robust, ventral, ridged prostrate setae pointing basally. Lamina parva tongue-shaped, covered with numerous median dorsal and lateral acuminate short spines. LP with broad base, base with two pairs of robust, ridged setae, one ventrolateral with massive sockets and pointing laterobasally, another dorsolateral, flanking glans and pointing dorsally. Laterodistal margins of LP each with four long, ridged setae parallel to each other. Ventral face of LP with rectangle of four setae, two short, distal and two long immediately basal to those. Malleus functions as a support from where arise the rigid ‘finger’, which is the LP, and the soft sac, which is the follis of the glans. Follis almost without folds, with a well-marked dorsal furrow dividing it into left and right halves. Stylus smooth and simple, without head, mounted atop glans, with short pedestal and arising candelabrum-like from it. Skirt ungrooved, without an axis, pentagonal in dorsal view, folding over itself, with shallow-serrate margins. Coloration. Body and appendages uniform 53 Moderate Orange.   
 Sexual dimorphism (Fig. 19A–D): Ocularium of male is hugely developed in width and height, whereas that of female is normal-sized. Dorsal scutum of female is more rounded and has sharper constrictions.
