Figures 70 D, E , Maps 10, 21.

Type material. Holotype female ( CASENT9030916 ) and two paratype females ( CASENT9064719 and CASENT9064720 ) from montane rainforest at 1325m elevation in Parc National de Marojejy , Antsiranana Province, Madagascar, collected 18 November 2003 by B. L. Fisher, deposited in CAS.

Etymology. The species epithet is from a Malagasy word for difficult, sarotra; an adjective in apposition.

Diagnosis. Uduba sarotra are an Unclassified species ( Map 21 ) and females can be distinguished from those of other Uduba that have a divided cribellum by the form of the epigynum ( Fig. 70 D ): the epigynal plate lacks sclerotized lateral margin, not projecting laterally, ML short, limit- ed to anterior half of epigynal plate, CO hidden beneath ML, spermathecae path, if visible through epigynal cuticle, seen only posteriad of copulatory openings. Males are unknown.

Description. Male Unknown. Female (Holotype, CASENT9030916): Total length 10.50. Markings typical of Uduba . Carapace 3.80 long, 2.80 wide, 1.40 high; clypeus 0.20 high. Eye diameters: AME 0.13, ALE 0.20, PME 0.18, PLE 0.22. Chelicerae 2.00 long; sternum 1.90 long, 1.55 wide; labium 0.80 long; palpal coxae 1.45 long. Divided cribellum. Spination: palpus–femur d0-1-1, patella p1-0, tibia p2-0, tarsus p2-1-0, v0-0-1; leg I–femur d0-1-0, p0-0-1, tibia v2-2-2-2, metatarsus v2-2-3; leg II–femur d0-1-0, tibia r0-1-0, metatarsus v2-2-3; leg III–femur d1-0-0, tibia d0-1-0, p0-1-1-0, v0-1-1-0, r0-1-1-0, metatarsus p1-2-2, v2-1-2, r1-1-2; leg IV–femur d1-0-0, tibia v1-1-2, r0-0-1, metatarsus p0-0-2, v0-2-2-2, r0-0-2. Scopulae: strong ventral on tarsi I-IV, metatarsus I, apex of metatarsi II and IV. Leg measurements: I: 2.80 + 1.40 + 2.40 + 2.20 + 1.60 = 10.40; II: 2.50 + 1.20 + 1.90 + 1.80 + 1.30 = 8.70; III: 2.00 + 1.10 + 1.10 + 1.50 + 1.10 = 6.80; IV: 2.80 + 1.30 + 2.40 + 2.60 + 1.40 = 10.50; palpus: 1.40 + 0.70 + 0.70 + NA + 1.30 = 4.10. Leg formula 4123. Female genitalia: epigynal plate without depressed atrium, posterior margin at epigastric furrow convex ( Fig. 70 D ), plate width 1.37 times length, ML and LL not clearly defined, CO beneath longitudinal grooves in anterior half of plate, distance between CO 0.41 times epigynum width, CO origin at 0.44 of epigynum length, extant of plate laterad to CO equals 0.19 times plate width. Vulva ( Fig. 70 E ) with spermathecal ducts forming two-and-a-half longitudinal loops, vulva length 0.67 times width, FD widely spaced, vulva width 3.86 times distance between FD.

Variation. Female (N= 3): Total length = 7.30–11.10. Carapace length / width = 1.36–1.50, carapace height / width = 0.50–0.73, PER / carapace width = 0.46–0.48, PER/OAL = 3.00–3.10, PER/AER = 1.17–1.40, OAL/OQL = 1.00–1.18, OQP/ OQA = 1.23–1.39, clypeus height / AME = 1.54–1.67, cheliceral length / clypeus height = 9.00–10.00, sternum length / width = 1.23–1.35, palpal coxa length / width = 2.00–2.17, femur I length / carapace width = 0.92–1.00, metatarsus I length / carapace width = 0.79–0.88, femur IV length / carapace width = 1.00–1.09, palpal tarsus length / carapace width = 0.46–0.53, palpal tibia length / palpal patella length = 1.70–2.17, palpal tarsus length / palpal tibia length = 1.86–2.17, palpal tarsus length / palpal femur length = 0.93– 1.00, palpal tibia length / palpal patella length = 0.90–1.00. Male variation unknown; U. sarotra are known only from females.

L. Fisher, [BLF9082] ( Uduba sarotra Holotype, CASENT9030916 , 1♀, CAS), (paratype, CASENT9064719 , 1♀, CAS), (paratype CASENT9064720 , 1♀, CAS) .

Natural history. Collection records suggest that the cribellate Uduba sarotra occur only in montane rainforest.

Distribution. The species Uduba sarotra is known only from the type locality at Parc National de Marojejy in Antsiranana Province in northeastern Madagascar (Maps 10, 21).
