Redescription of Lystrocteisa Simon, 1884 (Araneae: Salticidae) from New Caledonia Author Patoleta, Barbara Author Gardzińska, Joanna text Zootaxa 2013 3646 587 592 http://www.mapress.com/zootaxa/2013/f/zt03646p592.pdf journal article zt03646p592 50C87148-49F6-4BB2-BBF3-B5E6DD52B282 Genus Lystrocteisa Simon, 1884 Lystrocteisa Simon 1884, p. 228; Peckham & Peckham 1885, pp. 272-273; Simon 1901, pp. 478-481. Type species: Lystrocteisa myrmex Simon 1884, by monotypy. Diagnosis. Cephalothorax moderately low, with posterior lateral eyes located on protuberances. Legs I longer and more robust than others, armed with 3 and 2 pairs of ventral spines on tibiae and metatarsi respectively. Palpal organ with embolus fixed to the tegulum. Epigyne with posterior notch. Description. Myrmecomorph spiders, 3.5- 4 mm long. Sexes similar in appearance, though males with more distinct transverse constriction of the cephalothorax, cheek swelling (Fig. 21 "cs" ), and raptor-like development of first legs, with strongly swollen tibiae and relatively longer trochanters I (Figs 12, 18). Female carapace with granulated integument on the dorsum. Cephalothorax low and relatively narrow ( CW <70% of CL ) in both sexes, with distinct posterior slope and constriction between posterior medial and lateral eyes (Fig. 22). Eye field trapezoid, long (about 60% of CL ), PME considerably more distant from PLE than from ALE, the last ones situated on protuberances. Fovea short, located behind PLE. Clypeus very narrow (about 10% of AME diameter). Chelicerae of fissident pattern, with frontal surfaces flattened and rugose (Figs 10, 17). Endites slightly divergent, lateral modifications possible (Fig. 24 "ho" ). Sternum scutiform (Figs 3, 25). Abdomen elongate ovoid, slightly constricted in anterior third, pedicel moderately long, visible in dorsal view (Fig. 22). Legs I the longest and more robust than others. Trochanters I elongate (but shorter than tibiae I : about 50% of tibiae I length). Ventral spination of first legs: tibia 2-2-2, metatarsus 2-2. Legs formula: I-IV-III=II or I-IV-II-III. Palpal organ: cymbium unmodified, tegulum triangular in ventral view (Figs 11, 19), embolus thin, anteriorly set (at 10 o'clock position), tibial apophysis short and slender (Fig. 20 "rta" ). Epigyne: copulatory openings widely separated, insemination ducts and spermathecae elongate and curved, the last ones accompanied with accessory glands (Fig. 7).
