![]() ![]() No distinct sexual dimorphism between sexes, except males smaller in size with relatively longer legs.īody size: Females 3.2–6.0 mm, males 2.5–3.8 mm.Ĭolour: Live specimens creamish white to greyish white, in some species carapace and legs pale green and abdomen with pink tint body colour fades in alcohol to cream or yellow-brown body setae vary from white to almost translucent ( Fig. 36) the embolus is variable in length female with epigynal area raised, dome-shaped area with hood ( Fig. 1) the eyes are borne on small tubercles, with LE tubercles larger than those of the ME both eye rows are recurved the abdomen is round to oval with indistinct markings the male palp with VTA short, digitiform RTA elongated, with distal tooth ( Fig. However, after Loerbroks ( 1983) had revised the genus, a recommendation was made by Kraus and Loerbroks to recognize Thomisus hirtus as the type species of Heriaeus (ICZN 1988).ĭiagnosis: Heriaeus is characterized by the body and legs covered with erect setae and long hairs ( Fig. Simon ( 1918) then designated a new type for Heriaeus, H. Twenty years later, Simon ( 1895) designated Thomisus hirsutus Walckenaer, 1826 as the type species but it turned out to be a junior synonym of T. When describing Heriaeus, Simon ( 1875) included three species in the genus but did not designate a type species. Type species: Thomisus hirtus Latreille, 1819, designated by ICZN ( 1988). Ta - tarsus, Tib - tibia male genitalia: ITA- intermediate tibial apophysis, RTA-retrolateral tibial apophysis, VTA - ventral tibial apophysis.Ĭoordinates in the distribution records are provided as extracted from the South African National Survey of Arachnida (SANSA) database. The following abbreviations were used: measurements: CL - carapace length, CW - carapace width, TL - total length of body in dorsal view eyes: AER - anterior eye row, ALE - anterior lateral eyes, AME-anterior median eyes, LE - lateral eyes, ME - median eyes, MOQ - median ocular quadrangle, MOQ AW - median ocular quadrangle anterior width, MOQL - median ocular quadrangle length, MOQPW - median ocular quadrangle posterior width, PE - posterior eyes, PER- posterior eye row, PLE - posterior lateral eyes, PME - posterior median eyes legs: Fe - femur, Mt - metatarsus, Pat - patella. The description format and the abbreviations of morphological terms used in this paper follow those of Dippenaar-Schoeman ( 1983). Measurements have been taken with the ocular micrometer and are given in millimetres with 0.01 mm accuracy. Kruger).Ĭharacters were examined under 40x magnification using a Wild M3C light microscope fitted with a calibrated 10x micrometer ocular lens. A key is provided for both males and females.ĭitsong National Museum of Natural History (formerly Transvaal Museum), Pretoria, South Africa (M. In this paper ten new species are described, one species is synonymized and the three valid known species are redescribed. The material studied in this revision was collected mainly from grass and foliage, indicating that these spiders are mainly plant-dwelling. fimbriatus Lawrence, 1942 based on a female. crassispinus Lawrence, 1942, based on a male specimen, and H. A further two South Africa species were added later: H. latifrons Lessert, 1919 from East Africa. transvaalicus Simon, 1895, was described from South Africa, followed by H. Loerbroks ( 1983) revised the European species of Heriaeus and provided short notes on the African species. ![]() Their pilose bodies camouflage them well on grasses and foliage, and they are not easily seen. ![]() Living specimens are usually creamish white with tints of green and pink. 1), the oval-shaped abdomen and the presence of distinct eye tubercles and a wide clypeus ( Figs 2–6). Members of Heriaeus are small to medium-sized spiders characterized by numerous, strong erect setae and fine hairs covering the body and legs ( Fig. Prior to this study, Heriaeus was represented by 25 species ( Platnick 2012), of which seven were known from Africa and four from the Afrotropical Region. The genus Heriaeus Simon, 1875 is characterized by the lateral eye tubercles being separated from each other and the anterior lateral eye tubercle being larger than the posterior eye tubercle ( Jézéquel 19). ![]()
