Leptus (Leptus) chiusicus nov.sp.

D i a g n o s i s:thenewspeciesbelongs to the group species with one palpgenuala and

more than four setae between coxae II – III. Larva with the following features: fD 96, AW 81-82, AL 53, PL 47, Ta I 145-150, Ti III 209-217, fn Ta I-III 23-24, 20-22, 22, fn Ti I-III 14, 14, 14. M a t e r i a l e x a m i n e d: the holotype and paratype were collected by R. Haitlinger on

undetermined Orthoptera, 3 July 2013 in Chiusa Sclafani (37º41’ N, 13º16’ E), Palermo prov.,

Sicily. The holotype and paratype are deposited in Museum of Natural History, Wrocław

University (MNHWU), Poland.

D e s c r i p t i o n (larva): Idiosoma with 96 barbed setae. One pair of eyes ( Fig. 1 ). Scutum in a very small degree, longer than wide (in paratype slightly wider than long), with two barbed scutalae AL and PL, AL> PL. Anterior sensillae ASE shorter than posterior sensillae PSE, both with setules on their distal part ( Fig. 3 ). Ventral surface of idiosoma bearing two barbed setae 1a, two barbed setae 2a, eight barbed setae between coxae II-III, two setae 3a and 28 slightly barbed setae behind coxae III. Setae 1b about twice longer than setae 2b and distinctly longer than setae 3b ( Fig. 2 ). NDV = 124.

Gnathosoma with smooth hypostomalae. Palpfemur and palpgenu each with one barbed seta. Palptibia with three barbed setae; palptarsus with 6 (5N, 1B) normal setae, solenidion and eupathidium ( Fig. 4 ).

Leg setal formula: Leg I: Ta 1ω, 2ζ, 23 (24 in paratype); Ti 2φ, 1κ, 14; Ge 1σ,1κ, 8, Tf 5 ; Bf 2, Tr 1, Cx 1 ( Fig. 5 ). Leg II: Ta 1ω, 2ζ, 20 (22 in paratype) ; Ti 2φ, 14; Ge 1κ, 8; Tf 5; Bf 2; Tr 1, Cx 1 ( Fig. 6 ). Leg III: Ta 1ζ, 22 ; Ti 1φ, 14; Ge 8; Tf 5; Bf 1; Tr 1; Cx 1 ( Fig. 7 ). Legs length: I 780 holotype, 767 paratype, II 656 holotype, 654 paratype, III 810 holotype, 819 paratype. IP = 2246 holotype, 2240 paratype.

Measurements are given in Table 1.

E t y m o l o g y: The species was named after the place where the holotype was collected.

R e m a r k s Leptus (Leptus) chiusicus nov.sp. belongs to the species group with one palpgenuala and more than four setae between coxae II and III. This group includes: L. (L.) ursyni HAITLINGER, 1991 known from Chile, obtained from Scotobius planatus ERICHSON, 1834 ( Coleoptera , Tenebrionidae ) and L. (L.) charan yca FAIN, 1991 known from Belgium, obtained from Charanyca trigrammica HUFNAGEL, 1766 ( Lepidoptera , Noctuidae ) ( FAIN 1991, HAITLINGER 1991). It differs from L. (L.) ursyni in two setae between coxae I vs. four setae, two setae between coxae II vs. six setae, eight setae between coxae II-III vs. 15 setae, the shorter AW (81-82 vs. 134-138), PW (94-95 vs. 138-142), PsFd (58-62 vs. 76), AP (15-19 vs. 24) and longer seta 1a (37-42 vs. 30-32) and from L. (L.) charanyca in the shorter AL (53 vs. 69-73), PL (47 vs. 66-67), longer TaI (145-150 vs. 115), Ti III (209-217 vs. 165), fD (96 vs. 146) and fnTi (14-14-14 vs. 15-15-15).
