Parasyrisca arrabonica est une espèce d'araignées aranéomorphes de la famille des Gnaphosidae.

Description. Male. Habitus as seen in Figs 13-14. Total length 7.1. Carapace 2.6 long, 2.1 wide. Femur II 2.2 long. Eye sizes and interdistance: AME 0.16, ALE 0.14, PME 0.14, PLE 0.12; AME - AME 0.08, AME - ALE 0.04, PME - PME 0.1, PME - PLE 0.14, ALE - PLE 0.16; MOQ lenght 0.46, front width 0.36, back width 0.4.
Leg spination: femora ; I,II d 1-1-0, p 0-0-1; III d 1-1-0, p 0-1-1, r 0-0-1; IV d 1-1-0, (without prolateral spine), r 0-0-1; tibiae I v 2-2-0; II v 1-1-0; III v 1-1-2, p 1-1-0, r 1-1-0; IV v 1-2-2, p 0-1-1, r 1-0-1; metatarsi I-II v 2-0-0; III v 2-0-2, p 2-0-2, r 2-0-2; IV v 1-0-2, p 2-0-2, r 2-0-2.
Palps (Figs 1-3, 7-11) with strong, well developed, long RTA (Figs 2-3), reach ¼ of cymbium length (Figs 2-3, 7-9). RTA tip seems abrupt in lateral view. Conductor (Fig. 10) twisted, directed upward (Fig. 2), gradually tapered at end, twisted in shape (Figs 2, 10), with thin tip (Fig. 8) clearly visible in frontal and lateral views. Embolus unusually long, largely covered by conductor, visible only after conductor is removed (Fig. 11). Terminal apophysis thick, curved toward sides (Figs 2-3, 10).
Colouration. (Fig. 12) Legs yellowish-brown, tibia, metatarsus and tarsus slightly darker than proximal segments. Carapace also yellowish-brown, but head somewhat darker. Chelicerae, cymbia, gnathocoxae and labium also darker brown. Abdomen grayish–brown with a few narrow, light brown stripes at the posterior end, just before the spinnerets.
Female. Total length 9.2. Carapace 3.3 long, 2.3 wide. Femur II 2.2 long. Eye sizes and interdistance: AME 0.16, ALE 0.14, PME 0.16, PLE 0.12; AME - AME 0.1, AME - ALE 0.04, PME - PME 0.12, PME - PLE 0.16, ALE - PLE 0.18; MOQ length 0.52, front width 0.36, back width 0.4. Leg spination: femora; I,II d 1-1-0, p 0-0-1; III d 1-1-0, p 0-0-1, r 0-0-1; IV d 1-1-0, (without prolateral spine), r 0-0-1; tibiae I v 2-2-0; II v 1-1-0; III v 1-1-2, p 1-1-0, r 1-1-0; IV v 1-2-2, p 0-1-1, r 0-1-1; metatarsi I-II v 2-0-0; III v 2-0-2, p 2-0-2, r 1-0-1; IV v 1-1-2, p 2-0-2, r 2-0-2.
Female genitalia (Figs 4-6) Epigyne elongate, with length/width ratio 1.7. Anterior hood twice as long as wide (Fig. 4), atrium elongated as in P. songi. Epigynal plate depressed at the posterior end, posterior ridge (PRE) invaginated from the posterior end having a two-pointed tip at the sides (Fig. 4). As seen in rear view (Fig. 6), PRE U-shaped (as the epigynal plate depressed), which is in an inverted position compared to other Parasyrisca species. Spermathecal ducts directed upwards and curved inwards (Fig. 5). Ducts significantly stronger than that of P. turkenica.
Colouration. Similar to that of male, but carapace with more distinct pattern: three radially directed dark stripes present on both sides of fovea.

Distribution. (Figs 18-19) Known from Hungary only. From the type locality (Győrszentiván) and from two collecting sites of the Kiskunság area: Bugac and Orgovány.
