Length 24 mm( vs. 23–25 mmin the original description, Carl 1902), maximum width of midbody body rings 2.6 mm. Coloration(live specimens) of dorsum ( Fig. 1) generally yellowish brown, but head, antennae and two broad lateral stripes dark brown and an axial line light brown. Legs yellowish brown, densely setose, relatively long, tibiae swollen ventrally and with brushes starting in leg pair 9 until three last pairs. Male coxae of leg pair 2 with a prominent gonapophysis. Antennaedensely setose, relatively long, in situreaching behind body ring 3 dorsally. Frons and clypeus smooth and setose. Integumentsmooth and shining. Limbus thin and entire. Paraterga strongly reduced, traceable as faint and arcuate sulci on body rings 2–4, missing thereafter posteriorly. Epiproct pointed, rather long, with a pair of dorsal and ventral spinnerets. Hypoproct subtriangular, its tip not produced ventrally. Sternal structures of male.Sternum between coxae of leg pair 3 (III) with a paramedian pair of bunches of setae. Sternum between coxae of leg pair 4 (IV) with a strong, linguiform, anteriad directed process beset with short setae on both sides of ventral face, but not medially. A subtrapezoidal densely setose process between coxae of leg pair 5 (V) ( Fig. 2). Two compact, but large, paramedian, circular groups of short setae on low bosses between coxae of leg pair 6 (VI). Two conspicuous, thin, paramedian tufts of very long, posteriad directed setae between coxae of leg pair 7 (VII) near caudal margin. A median field of short setae scattered between anterior group of similarly short setae and two long subcaudal tufts ( Fig. 3). Postgonopodal sterna with paramedian spines. Gonopods( Figs 4–9) complex, subcircular. Gonocoxite (cx) subcylindrical, about as long as densely setose prefemoral (pf). Femorite (fe) demarcated from postfemoral (psf) portion by a distinct cingulum both on mesal and lateral sides. A characteristic, small, slender, sometimes bifid, parabasal lobe (p) on solenophore (sph) (MCN 227; Fig. 6, and MCN 669; Fig. 7). Female. General coloration as in male, length 26 mmand maximum width of midbody 2.7 mm. Legs without tibiae swollen and with few setae. Paramedian cones on postgonopodal sternal smaller than those of the male.   Distribution: Southern Brazil(state of Rio Grande do Sul: Canela, Maquiné, Triunfo, Montenegro, Porto Alegre, São Leopoldo and Rio Grande).   Remarks: The type series of  C. intermediumwas stated to comprise three males ( Carl 1902), which is apparently inaccurate, or the others are lost. We were only able to find two syntypesfor study and selected the sole available male as the lectotype.   FIGURES 8, 9.  Catharosoma intermedium, male (MCN-575), left gonopod. 8, Medial view. 9, Ventromedial view.

( MCN 1008). Paratypefemale, same data as the holotype ( MCN 1468).   Diagnosis: Using the latest key ( Golovatch 2005a),  C. promatense n. sp.closely resembles some other species of the genus by the tip of the hypoproct being curved ventrad, much like in  C. bilineatumGolovatch, 2005(see Golovatch, 2005a: 812, fig. 2) and  C. mesoxanthum( Attems, 1898)(see Attems, 1898: 286-287, fig. 32), but  C. promatense n. sp.differs by the shape of parabasal lobe (p) of the solenophore which is very long and unciform, with a very long hyaline lobe next to it (Figs 13, 14).   Description: Male holotype(Figs 10, 11). Length 28 mmand maximum width of midbody 2.4 mm. Coloration(in alcohol): generally reddish brown, legs and antennae yellowish brown. Legs densely setose, relatively long, tibiae swollen ventrally. Male coxae of leg pair 2 with a prominent gonapophysis. Antennaedensely setose, relatively long, in situreaching behind body ring 3 dorsally. Frons and clypeus smooth and setose. Integumentsmooth and shining, pro- and metazona divided by a stricture. Ozopores lateral, faintly visible. Limbus thin and entire. Paraterga strongly reduced, arcuate sulci present until body ring 6, missing posteriorly thereafter. Epiproct pointed, rather long, with a dorsal and ventral pair of spinnerets. Hypoproct subtriangular, tip unciform, directed ventrad (Fig. 11). Sternal structures of male(Fig. 12). Sternum between coxae of leg pair 3 with a paramedian pair of setal bunches. Sternum between coxae of leg pair 4 with a shorter, linguiform, anteriad directed process beset with short setae on all process; a subtrapeziform densely setose process between coxae of leg pair 5. Sternum between coxae of leg pair 6 with two, paramedian, circular tufts of long setae anteriad directed; two, paramedian tufts of long posteriad directed setae between coxae of leg pair 7. Postgonopodal sterna with paramedian spines like in many others species of the genus. Gonopods(Figs 13–17) highly complex, subcircular; gonocoxite subcylindrical with some long setae distoventrally, gonocoxite about as short as densely setose prefemoral portion; femorite longer than prefemoral portion; postfemoral portion with three sulci and a long hyaline process. Solenophore (sph) with a very long, unciform, parabasal lobe (p). Female. General coloration as in male, length 26 mmand maximum width of midbody 2.8 mm. Legs without tibiae swollen and with few setae. Paramedian cones on postgonopodal sterna as in male.   Distribution: The species is known only from the typelocality.   Etymology: The species epithet is an adjective in neuter gender, referring to the typelocality, “Pró-Mata”. 2576149791 1977-07-07 VII H.
