Daidalotarsonemus leonardi ; Attiah, 1970: 191; Smiley, 1972: 89; Lindquist, 1986: 319; Lin & Zhang, 2002: 61.

Diagnosis. Female: unknown. Male: Gnathosoma : Palpal length about 1/4 length of gnathosoma. Dorsum: Setae v1 slightly longer than sc2 (~25 and ~23, respectively), both longer than v2 (~20). Setae c1 slightly shorter than c2 (~26 and ~28, respectively) both shorter than d (~37). Venter: Apodemes 5 visible at posterior end of poststernal apodeme. Legs: Sensory cluster of tibiotarsus I incomplete. Solenidion ω of tarsus II 4. On femorogenu IV, seta v’ G around five times longer than v’ F (~34 and ~7, respectively). On tibia IV, seta v’ Ti around 2.3 times longer than tibia IV itself (~86 and ~38, respectively). Larva: unknown.

Redescription:

Gnathosoma : subtriangular in ventral view, length 32, maximum width 27; dorsal apodeme distinct. Setae dgs 14 serrate and vgs 8 smooth; Palps moderately long 8, with 2 small subterminal setae and terminal projections. Pharynx fusiform, length 14 and width 8 at widest region.

Idiosoma—dorsum: length 165, maximum width 93. Prodorsal shield trapezoidal. Length of dorsal setae: v1 25, v2 20, sc1 49, sc2 23, c1 26, c2 28, d 37, f 40. All setae slender and serrate. Distances between dorsal setae: v1–v1 11, sc1–sc1 35, sc2–sc2 49, v1–sc2 33, c1–c1 75, c2–c2 93, c1–c2 58 d–d 55, f–f 22. Seta sc2 laterad and slightly posterior to sc1.

Idiosoma—venter: setae 1a 5; setae 2a 12; setae 3a 13 located near anterior end of apodemes 3; setae 3b 15. Apodeme 1 fused to anterior end of prosternal apodeme; apodeme 2 fused to prosternal apodeme. Prosternal apodeme conspicuous between coxisternal plates I but inconspicuous between coxisternal plates II, extending close to sejugal apodeme. Lines of fusion between coxae III and IV with venter of idiosoma mostly conspicuous; connecting between 3, 4 and poststernal apodemes diffuse.

Legs: lengths (measured from femur to tarsus): leg I 66, leg II 51, leg III 82, leg IV 130. Number of setae: leg I: 2-4-3(1)+5(1), leg II: 3-3-3-4(1), leg III: 1-3-4-3. Due to type condition, it was not possible to count precisely all setae on legs. Solenidion ω of tarsus I 4. Sensory cluster of tibia I composed of φ1 3, and famulus k 4, both inserted at approximately same level. Seta d of tibia I 18 serrate. Solenidion ω of tarsus II 4. Seta d of tibia II 19 serrate. Trochanter IV wider than long, seta v’ 8, serrate. Femorogenu IV length 70 and width 31 at v’ F level; anterior margin convex, posterior margin slightly convex at proximal third. Seta v’ F 7 serrate. Setae v’ G 34 and l” G 13 serrate. Tibia IV length 38; solenidion φ 8; seta v’ Ti 86, serrate. Tarsus IV short, bearing 3 smooth setae, lengths: tc” 7, pv” 6 and u’ 5.

Type material deposition: holotype ♂ deposited at USNM .

Locality: Jamaica ( Smiley 1967).
