Grayenulla

Abstract: Genera Grayenulla from Australia and Paraplatoides from Australia and New Caledonia are diagnosed, described and illustrated. Marptusa tenerrima L. Koch, 1979 is established as the generic type of Paraplatoides. Holoplatys caledonica Berland, 1932 is included in Paraplatoides, as are four other new species: P. longulus, P. hirsti, P. christopheri and P. nigrum. Five new representatives of Grayenulla are described: G. wishartorum, G. nova, G. dejongi, G. waldockae and G. australensis. ZABKA, M., 1992.

Records of the Australian Museum 44(2): 165-183. 165 Material and Methods The paper is based on material from several collections listed below. Dimensions are given in millimetres. Details of terminology are presented for each genus separately. Format of leg spination follows Platnick & Shadab (1975). Dissected epigynes were digested in lactic acid for 10 to 30 minutes or in 10% KOH for 12 to 48 hours at room temperature, rinsed in distilled water and stained in ethanol solution of chlorazol black E under control and mounted in glycerin. The drawings were made using grid system.

Parapiatoides n.gen. Type species. Marptusa tenerrima L. Koch, 1879 by original designation. Etymology. The generic name is a random combination of letters and it is masculine in gender. o a Diagnosis. The body flat and elongate. In some species similar to Holoplatys. Spines on first tibia always present, male palpal organ club-shaped, cymbium truncate at the top, embolus and insemination ducts long, the last coiled. Description (Fig. 1 ). Medium spiders, ranging from 4.30 to 7.20 mm in length. The body flat, narrow and elongate. Chelicerae of unident pattern, with 2 promarginal teeth and 1 retromarginal tooth. Legs I the strongest, Holoplatys-like, or more elongate, usually with prolateral (p) and retrolateral (r) spines on tibiae (t) and metatarsi (m). Legs IV longer than Ill. Genitalia almost identical in all species. Male palpal organ club-shaped, with tegular furrow (tf), embolus (e) long and thin, tibia (t) short and wide with single retrolateral
