Micaria galilaea n. sp.

Figs 36–41

Type material. Adult male holotype from Har Meron, Galilee, Israel, leg. Iris Musli, May 7, 2007, pitfall trap ( HUJ 15538). Female unknown.

Etymology. The specific name refers to the type locality zone.

Description. Small slender black body marked by two indistinct light spots on upper part of opisthosoma. No scutum. Eyes in two rows with small AME touching larger ALE ( Figs 36 a–b). Chelicerae lack teeth.

Labium wider than long ( Fig. 37 ). Legs yellow except for black femora; tibiae and metatarsi of two anterior pairs armed with pairs of macrosetae.

Male. Measurements (holotype + 1ɗ; holotype listed first): total length 2.0, 2.1; carapace length 0.95, 0.95, width 0.70, 0.70, index 1.36, 1.36; labial index 0.86, 0.77; clypeal index 2.75, 1.8; MOQ index 6.33, 5.94; legs length: I 2.55, 2.40, II 2.10, 1.90, III 1.85, 1.80, IV 2.80, 2.75; patella-tibia index 0.94, 0.84.

Palpus. Small with round bulging whitish tegulum, and brown tapering embolus ending with fine, transparent hooked tip ( Figs 38, 39 ). Very large, mesally concave, tibial apophysis rises to about half length of bulb ( Figs 38–40 ). Palpal femur bears ventral, setaceous hump ( Fig. 41 ).

Diagnosis. Based on male. The peculiar shape of the palpal distended tegulum with the hooked embolus, the sizable tibial apophysis, and the femoral hump distinctly separate M. galilaea from all other Micaria species.

Distribution. Israel. Records: Mt. Meron, Adullam Reserve.
