Listropsoralges marmosae Fain, 1965: 20   , figs. 12, 13, 15; Fain and Lukoschus 1970: 50, 1979: 389; Bochkov and Wauthy 2009: 270.

Redescription. FEMALE (2 paratypes). Body 205–210 long and 140–145 wide. Gnathosoma   . Ventral retrorse spurs of subcapitulum with 2 apices. Dorsum. Dorsal shields without ornamentation. Propodonotal shield about 60 long. Setae si almost 7 times shorter than se. Hysteronotal shield 95–100 long. Setal alveoli c1 absent. Setae e1 represented by minute setae. Posterior margin of opisthosoma without nipple-like median projection. Venter. Epigynum about 45 wide. Setae 1a and 3a distinctly thickened, 6 wide in basal part. Setae 4b and 4a subequal. Length and width of opisthogastric shield subequal, about 40 long. Setae h3 slightly thickened, 3.3 times longer than setae ps2 and 2.6 times longer than ps3. Legs. Genua I and II with distinct ventro-antiaxial retrorse spur. Setae d I slightly longer than solenidion ω 3 I. Legs III about 70 long. Pretarsi III moderately developed. Legs IV moderately developed, about 50 long. Pretarsi IV with ambulacral disc. Lengths of setae: si 9–10, se 55–57, c2, d2, e2, h1, and ps1 —all 12–17, cp 24–25, c3 and f2 4–6, e1 4–5, h2 95–100, h3 23–25, ps2 8 and ps3 9–10, 1a 28–30, 3a 29–30, g and 4b 7–9, 4a 5, w1 I and II about 20, ω 3 I 16–17, φI about 28, φII about 35, φIII about 20, φIV 4–5, σ 1 I 25–27, σII 6–7, and σIII about 10.

MALE (paratype). Body 155 long and 115 wide. Gnathosoma   . Ventral retrorse spurs of subcapitulum with 2 apices. Dorsum. Dorsal shields without ornamentation. Propodonotal shield 45 long. Setae si almost 9 times shorter than se. Hysteronotal shield 75 long. Setal alveoli c1 absent, setae cp only slightly thicker than c2 and c3, setae f2 slightly thickened. Setae e1 represented by minute setae. Posterior margin of hysteronotal shield widely concavated. Venter. Retrorse spur of coxal fields III distinct. Fleshly-like projections bearing setae h2 and h3 absent. Diameter of adanal suckers about 7. Opisthosomal lobes about 17 long. Maximum distance between opisthosomal lobes 25. Legs. Legs III about 80 long. Legs IV about 25 long. Lengths of setae: si 6, se 60, c2, d2, e2, f2, and 1a – all 8–10, cp 25, c3 15, e1, h1, ps2, ps3, 4a, 4b and g —all 3–5, h2 90, h3 19, 3a 10, ps1 25, w1 I and II about 18, ω 3 I 20, φI and II about 33, φIII 20, φIV 5, σ 1 I 30, σII 8, and σIII 7.

FEMALE TRITONYMPH (3 paratypes). Idiosoma   170–175 long and 130–145 wide. Gnathosoma   . Ventral retrorse spurs of subcapitulum with 2 apices. Dorsum. Dorsal shields without ornamentation, distinctly separated from each other. Setae se 63–65 long, 5 times longer than si. Setae d2 located on hysteronotal shield, setae e2 located off hysteronotal shield. Legs. Pretarsi III present. Small fold present near leg IV.

Type material examined. Two female, 1 male and 3 female tritonymph paratypes ( IRSNB) from Gracilinanus microtarsus   ( BMNH # 13.7.8.14.18), BRAZIL: Santa Catarina State, Joinville City , 26°18'18"S, 48°50'46"W, date unknown, coll. Rothschild. GoogleMaps  

Holotype deposition. Holotype female (not examined) is deposited in BMNH   .

Non-type material examined. Four females and 4 males from Marmosa robinsoni fulviventer   , PANAMA:

Perlas Archipelago, San Miguel Island , 08 27’00’’N, 78 51’00’’W, 5. 08. 1970, coll. Ritte. Five GoogleMaps   males and 2 females from Marmosa isthmica   , PANAMA: Panama Prov., Rodman United States Naval Reservation , 08 57’00’’N, 79 35’00’’W, 21. September 1972, coll. Guerrero. GoogleMaps  

Host range and distribution. This species is known from Gracilinanus microtarsus   from Brazil (Santa Catarina) ( Fain 1965), Marmosa robinsoni fulviventer   and M. isthmica   from Panama ( Bochkov & Wauthy 2009).

Remarks. The record of this species from Caluromys derbianus from Panama by Bochkov and Wauthy (2009) should be referred to a new species Listropsoralges similis   sp. n. We found the female paratype of L. marmosae   from Marmosa murina   from French Guiana which was considered to be lost ( Bochkov & Wauthy 2009). This specimen undoubtedly belongs to L. faini Bochkov and Wauthy, 2009   .
