  • Material: 1 female holotype, 1 male allotype, 1 female paratype Phlegra stephaniae Proszynski Israel: Arava, Kibbutz Qtura, pomelo grove, 8.I.95 Y. Lubin. [sp. 429]

    Etymology. Named for Dr Stefania Heciak, of Siedlce, Poland, an Arachnologist who has recently contributed valuable redescriptions of types of over 20 species of Phlegra (a PhD thesis, publication in preparation for print), which I used in my studies, and also consulted my identifications, including this species.

    Diagnosis. Typical stripped pattern, lighter than in other species, particularly in females, in which dark streaks are reduced to thin, light brown lines. Pedipalps contrasting dark, embolus long and thin, broader near edge of bulbus, space between tibial apophyses slit like, tips of apohyses slightly bent. Epigyne: angular meeting point of anterior rims located in the mid length of epigyne.

    Male

    Cephalothorax: thorax and upper sides of cephalothorax light yellow with thin light brown streak on dorsum: one median and two marginal. Eye field dark brown, covered with inconspicuous adpressed, colorless setae; there are remnants of two whitish lines of denser and longer whitish setae running along eye field from a white spot on median rims of ALE, medially to eyes II and III and joining light thoracal streaks. These white lines may be much more conspicuous in some specimens.

    Abdomen with typical light and dark stripes pattern. Two median light yellow and two darker brown stripes, whose width are 1/5th of the abdomen width each, marginal light stripes are 1/10th of abdomen width. Upper sides light greyish brown, lower whitish. Dark streaks, covered with brown adpressed setae, light yellow streaks with colorless setae.

    Frontal aspect. Dorsal surface of eye field appear in this position black with fawn adpressed setae, a striking spot of white setae above medial half of ALE rim, the remaining half has inconspicuous fawn setae. Orbital setae around AME dorsally fawn with a few white, laterally greyish, ventrally colorless. Clypeus low, slightly higher than 1/3rd of AME diameter, space beneath AME is greish brown, with slightly lighter median vertical line, with stronger setae dark brown, pointed diagonally down. Part of these setae overhang diagonally cheliceral bases. The dark area beneath AME is delimited laterally by light yellow area running from the rim of ALE to carapace edge and extending onto sides of cephalothorax, upper half of that lighter area, under ALE rim, is covered with conspicuous white, adpressed setae. Chelicerae laterally brown, medially fawn, with lighter, almost white apical part. That contrasts with black cymbium (with a whitish grey tip), tibia and medial half of patella of pedipalps, the retrolateral half of patella is lighter, grey with a spot of white setae. Palpal femur is dark grey, with a crest of longer white setae along its dorsal surface. Legs I in this position are light yellowish grey, tibia and metatarsus I fawn; prolateral surface of femur I is darkened, which on femur II is followed by narrower dark streak.

    Palpal organ resembling Phl. particeps, from which seem to differ by slightly broader bulbus, posterior part of protruding tip of embolus seem to be broadened.

    Ventral aspect light greyish yellow, abdomen whitish.

    Female

    Cephalothorax yellow with dark eye field and two thin, light brown streaks of adpressed setae along marginal edges of dorsal surfaces of thorax and upper lateral surfaces. There are remnants of median streak of dark adpressed setae on slope of thorax, which may suggest presence of median streak in some specimens, dividing light dorsal surface into two light streaks, apparently somewhat broader than the dark median one, just like in males. Eye field dark brown (in the younger specimen dark olive brown) with inconspicuous colorless, adpressed setae and sparse black bristles.

    Abdomen whitish yellow, with two light greyish brown pigmented streaks, thinner than three light streaks, there is also a thin dark rim on the edge with sides. The setae on the dorsal surface are very inconspicuous, small and sparse, dark. Spinnerets yellowish grey.

    Frontal aspect: upper part of face dark with tiny white setae, eyes I surrounded by orbital setae dorsally yellow, ventrally whitish. Space beneath eyes light yellow, without any contrasting setae.In the paratype specimen clypeus is light grey, also without contrasting coloration, but partially hidden by a triangular patch of inconspicuous long whitish setae, protruding from under eye rims diagonally forward and down, there are also thin and colorless, almost invisible sparse setae overhanging cheliceral bases. Chelicerae yellow. Pedipalps whitish yellow, with tibiae and tarsi yellowish brown, covered with upright, dense and long, colorless setae. Ventral aspect almost uniformly whitish

    Legs yellowish or yellow except tibiae and metatarsi I-IV fawn, femora I-II with prolateral surface darkened or with dark streak, covered with small and sparse dark setae.
