Figs 1–17
Hasarius dispalans Thorell, 1892: 440 –443, 477 (male holotype from Java, Indonesia, SMNH, NHRS-KASI19, examined).
Cytaea dispalans: Prószyński & Żabka, 1983: 576, fig. 17; World Spider Catalog 2015.
Cytaea guentheri Thorell, 1895: 388 –390 [one male syntype from Burma (Myanmar), SMNH, NHRS-KASI18, here designed as lectotype, examined]; World Spider Catalog 2015, new synonymy.
Cytaea aenoemicans Simon, 1902: 393 (male holotype from Lombok, Indonesia, Fruhstorfer, MNHN 20096, examined); World Spider Catalog 2015, new synonymy.
Justification of the synonymies: The detailed study of the types of C. guentheri and C. aeneomicans showed that these specimens have all the diagnostic characters found in the holotype of Hasarius dispalans, both in general appearance and palpal structure (Figs 1–17).
Additional material examined. BORNEO: 2♂, Keningau, Crocker Range, 5°26' N, 116°08' E, degraded 20 year old isolated forest CRII.1, canopy fogging, Melanopis (Euph.), W. Sabah, 23 June 1905, A. Floren leg., CDML; 1♂, Sorinsim, 6°6' N 116°50' E, secondary forest 15 year old, Vinex pinnata, loc 42, canopy fogging, 19 June 1905, W. Sabah, A. Floren leg., CDML.
Diagnosis. Unlike in other Cytaea species, the embolus is short and not spiralled (Fig 16–17). Although this species does not have the typical Cytaea palp structure, all the following Cytaea characters are found: the two-cusp tooth on retromargin of chelicerae and 3 to 6 teeth on promargin, lateral spines on all tibiae, patellae and metatarsi, and dorsal spine near the base on tibiae. Unlike similar genera found in the Pacific area (like Ascyltus Karsch, Euryattus Thorell and Servaea Simon), Cytaea species, as well as C. dispalans, have short tibia and patella in the male palp, being as wide as long or wider (Berry et al. 1998).
Redescription. Male (holotype of H. dispalans). Cephalothorax chestnut-brown, covered with sparse brown hairs and brown and white scales, more numerous on sides (Figs 1, 8, 12). Eye surroundings black. Eye field wider than long, slightly narrowing posteriorly (trapezoid) (51% of CL). PME halfway between PLE and ALE. Fovea short, located between PLE. Abdomen elongate, with more or less contrasting pattern of light and dark patches, covered with brown scales (Figs 1, 8, 12). Spinnerets grey-brown. Clypeus orange with darker margin, narrow (30% of AME diameter), with same protruding setae (Fig. 4). Chelicerae short, vertical, chestnut-brown (Fig. 4); promargin with three or four teeth, retromargin with one bicuspidate tooth (Fig. 5). Endites and labium not distinctive, brown with yellowish chewing margins. Sternum longer than wide, light-brown to pale (Figs 2, 9, 13). Venter grey-brown to pale with little darker wide stripe and small grey-brown posterior spot. Pedipalps (Figs 6–7, 10–11, 14–17) orange-brown, femur with 1-1-3 dorsal spines, RTA slightly hooked apically, tegulum with posterior lobe, seminal duct well visible, meandering. Legs I brown, coxae–patellae ventrally lighter; spination: fI: dorsal 1- 1-5; pI: prolateral 1, retrolateral 1; tI: dorsal 1-2, prolateral 1-1, retrolateral 1-1, ventral 2-2-2; mI: prolateral 1-1, retrolateral 1-1, ventral 2-2. Other legs light brown, lighter ventrally, with numerous spines. Leg formula: III-II-IV- I. Dimensions. CL 2.20, CW 1.87, CH 1.30, AL 2.20, AW 1.30, EFL 1.12, AEW 1.64, PEW 1.42, leg I: 4.80 (1.42 + 0.81 + 1.01 + 1.02 + 0.54), leg II: 4.96 (1.56 + 0.84 + 1.00 + 1.01 + 0.55), leg III: 5.37 (1.77 + 0.79 + 0.99 + 1.23 + 0.59), leg IV: 4.87 (1.59 + 0.62 + 0.98 + 1.15 + 0.56).
Female. Unknown.
