M a t e r i a l e x a m i n e d: 1 l. Locus typicus: Sicily, Roccamena, 17 September 2016 from undetermined Orthoptera ; coll. R. Haitlinger. Holotype deposited in the Museum of Natural History, Wrocław University ( MNHWU), Poland.

D i a g n o s i s: Scutum trapezoidal with nasus. Tarsus I with two solenidia, genu III with one solenidion. Ta I 220, Ta II 200, Ta III 374, AL 66, PL 69, IP 2276.

D e s c r i p t i o n (larva): Dorsun with 32 barbed setae placed on platelets, longer setae placed in anterior part of idiosoma. Laterally of scutum two pairs of circular eyes on platelet, anterior 18, posterior 26 ( Fig. 1 View Figs 1-5 ). Scutum trapezoidal with nasus, lateral margins straight, posterior margin weakly concave. Scutalae AL and PL with short barbs, PL> AL; sensillary setae ASE and PSE barbed, PSE barbed only in distal part, PSE over twice longer than ASE. Beyond PSE short line ( Fig. 3 View Figs 1-5 ). Ventral side of idiosoma with setae 3a and behind coxae III 39 barbed setae placed on small platelets. Coxae I with two setae: 1a and 1b, coxae II and III each with one seta; all setae barbed ( Fig. 2 View Figs 1-5 ).

Gnathosoma robust, with barbed hypostomala (bs) and nude galeala (cs). Short seta elcp present. Palpfemur and palpgenu each with one barbed seta, palptibia with three barbed setae ( Fig. 4 View Figs 1-5 ). Palptarsus with 6 normal setae with small barbs, ω and ζ ( Fig. 5 View Figs 1-5 ).

Leg setal formula: Leg I: Ta I 2 ω, 2 ζ, 43; Ti 2 φ, 1κ, 8; Ge 1 σ, 1 κ, 4; Tf 5 (right leg 4); Bf 1; Tr 1; Cx 2 ( Fig. 6 View Figs 6-8 ); Leg II; Ta 1ω, 2 ζ, 36; Ti 2φ, 8; Ge 1σ, 1 κ, 4; Tf 4; Bf 2; Tr 1; Cx 1 ( Fig. 7 View Figs 6-8 ). Leg III: Ta 1ζ, 41; Ti 1 φ, 6; Ge 1 σ, 4; Tf 4; Bf 2; Tr 1; Cx 1 ( Fig. 8 View Figs 6-8 ).

E t y m o l o g y: The name of the species is based on the name of the place where the holotype was collected.

R e m a r k s: Cretessenia roccamenaica nov. sp. differs from C. leoni in the longer W (202 vs. 178), AL (66 vs. 50), PSE (126 vs. 80-94), 1b (76 vs. 32), Ta I (220 vs. 180- 190), Ta II (200 vs. 180), Ta III (374 vs. 244), shorter 1a (40 vs. 68) and shape of scutum.
