Morphological data ( based on new larval materials of L. saboorii ) Idiosoma – Oval, dorsal surface with 40 normal setae. All dorsal idiosomal setae barbed and blunted. Dorsal propodosoma with a quadrangular shape scutum; scutum punctate, wider than long with a concavity behind PL bases. Anterior margin of scutum straight, lateral margins convex ( Fig. 1 ). Scutum with 2 pairs of scutalae, AL longer than PL, both fully barbed and pointed. Anterior and posterior pairs of sensilla (ASens and PSens) with fine barbs throughout the length. PSens slightly longer than ASens ( Fig. 1 ). Two eyes present on each side of scutum, circular, not on platelets; anterior eye 20, posterior one 12 across. Ventral surface of idiosoma bearing 4 sternalae (1 a and 3 a ), 18 barbed and pointed setae behind coxae III. Sternala 1a longer than sternala 3a , both barbed and pointed. Coxae I–III each with one seta; coxala 1b longer than other coxalae; coxala 3b longer than coxala 2b ; all coxalae barbed and pointed ( Fig. 2 ). NDV = 40 + 18 = 58. Gnathosoma with smooth galealae ( cs ) and two hypostomalae, anterior hypostomalae ( as ) minute and posterior hypostomalae ( bs ) long and nude ( Fig. 3 ). Palpal femur and genu each with 1 barbed seta ( Fig. 3 ), tibia with three barbed setae, palpal tibial claw bifurcate with unequal prongs. Palpal tarsus with 8 setae including a solenidion and an eupathidium; one seta long ( Fig. 3 ). fPp = 0-B-B- BBB 2 -6Nωζ. Supracoxal setae ( eP ) minute (4 μm) and peg-like. Leg segmentation formula: 7–7–7. Leg setal formula: Leg I: Ta- 1ϖ, 18, 2ζ,1Cp, 24n; Ti- 2φ, 1K, 15n; Ge- 10, 1K, 9n; TFe- 5n; BFe- 4n; Tr- 1n; Cx- 1n ( Figs. 4–6 ). Leg II: Ta- 1ϖ, 2ζ, 1Cp, 23n; Ti- 2φ, 15n; Ge- 1K, 9n; TFe- 5n; BFe- 4n; Tr- 1n; Cx- 1n ( Figs. 7–9 ). Leg III: Ta- 1ζ, 22n; Ti- 1φ, 15n; Ge- 9n; TFe- 5n; BFe- 3n; Tr- 1n; Cx- 1n ( Figs. 10–13 ).
