Leptus (Leptus) mariani HAITLINGER 1991

T y p e m a t e r i a l e x a m i n e d: holotype (larva), Brazil, Rio Grande do Sul, Porto Alegre from Stolas festiva (KLUG 1829) ( Coleoptera : Chrysomelidae : Cassidinae); paratype same data. The holotype and paratype are deposited in Museum of Natural History, Wrocław University (MNHWU), Poland.

D i a g n o s i s: Palpfemur and palpgenu each with one seta, 4 setae between coxae II and III, AW 92-94, PW 113-118, AL 70-72, PL 71-79, GL 203-212, Ti III 260-286, ω on Ta I 70.

R e d e s c r i p t i o n (larva): (Standard measurements are presented in Table 1). Dorsal side of idiosoma with ~56 barbed setae (in paratype dorsal side is in very bad condition – number of dorsal setae is unknown). A pair of anterolateral eyes (Fig. 1) posterolateral to scutum. Scutum wider than long, punctate, with almost straight anterior margin, anterolateral angles obtuse, anterolateral borders short, nearly straight ; posterolateral borders almost straight. AC = 22-24. Anterior scutalae (AL) and posterior scutalae (PL) each with setules; AL a little shorter than posterior scutalae Anterior sensilla (ASE) shorter than posterior sensilla (PSE), both distally ciliated. (Fig. 3).

Ventral surface of idiosoma bearing one pair of 1a setae between coxae I, one pair of 2a setae between coxae II and 4 setae between coxae II and III; 20 setae beyond coxae III, all setae barbed. All coxae with one barbed seta. Setae 1b> 3b> 2b (Fig. 2).

Gnathosoma. Chelicera composed of basal segment and movable claw. Mouth surrounded with lamellar, narrowing fimbriae. Ventrally, a pair of nude hypostomalae (as), dorsally a pair of nude galaealae (cs) Palptrochanter without setae; palpfemur and palpgenu, each with one barbed seta. Palptibia with 3 barbed setae and odontus. Supracoxalae (elcp) present (Fig.4). Palptarsus with 1ω, 1ζ and 5 nude, normal setae (Fig. 5).

Leg setal formula: Leg I: Ta 1ω, 2ζ, 21B; Ti 2φ, 1κ, 14B; Ge 1σ, 1κ, 6B; Tf 5B; Bf 2B; Tr 1B; Cx 1B (Fig. 6). Leg II: Ta 1ω, 2ζ, 25B; Ti 2φ, 13B; Ge 1σ, 8B; Tf 5B; Bf 2B; Tr 1B; Cx 1B (Fig. 7). Leg III: Ta 6B; Ti 1φ, 14B; Ge 8B; Tf 5B; Bf 1B; Tr 1B; Cx 1B (Fig. 8), solenidion I (ω) 70, distal solenidion I (φ) 35 μm, proximal solenidion I (φ) 48. Legs length: I 958, II 842, III 999. IP = 2799. Supracoxala (elc) present on dorsal side, in terminal part of coxae I.

R e m a r k s: L. (L.) mariani belongs to the species group (Neotropical Region only) with one palpgenuala and palpfemorala, two sternalae between coxae I and coxae II, four setae between coxae II and III, Ti III with one solenidion and Ti III> 190. This group includes: L. (L.) tiranicus, L. (L.) nikanori, L. (L.) annikae and L. (L.) cyryli. It differs from L. (L.) tiranicu s in longer PW (113-118 vs. 90-102), AL (70-72 vs. 58-66), PL (71- 79 vs. 54-62), ISD (69-71 vs. 50-58), GL (203-212 vs. 172-184) and fD (56 vs. 46); from L. (L.) nikanori in 6 normmal setae on Ge I vs. 8 setae on Ge I and longer ω on palptarsus (23-26 vs. 15), depth of concave of anterior margin of scutum(AB) (2-3 vs. 8) and shorter as (27-30 vs. 46); from L. (L.) annikae in shorter hypostomalae as (27-30 vs. 50), ASBa (22-24 vs. 31) and longer DS (49-70 vs. 40-48) and from L. (L.) cyryli in ω on Ta I (70 vs. 49), Ta I (178 vs. 124), Ta II (152 vs. 130), Ta III (177 vs. 130) and leg I (958 vs. 832).
