Cymbium with dense cluster of long weak ensiform spines distributed over distal  2⁄  3of d surface. RTA swollen midway; covered with d and rd short spines; extended brush of c. 22 longer pointed spines on rv surface of mid region of tibial excavation; DTA hooked, terminated with c. 12 short spines. TEM contiguous with RTA; pv surface weakly textured. Bulb( Fig. 6B,C). Embolus broad, gently bent and twisted with small d embolic apophysis basally placed contiguous with rl embolic flange; flange with 4 folds, margin strongly convexly curved.  Scopula. Dense on Tarsi I and II, sparse on tarsi III and IV, incomplete on metatarsi I and II. Trichobothria. Palp: tarsi 8, tibia pd5 rd5. Leg I: tarsi 12, metatarsi 11, tibia pd6 rd5. Leg II: tarsi 11, metatarsi 11, tibia pd5 rd5. Leg III: tarsi 10, metatarsi 10, tibia pd5 rd5. Leg IV: tarsi 11, metatarsi 12, tibia pd7 rd7. Leg spination. Leg I: metatarsi v01002; tibia v0112. Leg II: metatarsi v0202; tibia v0113. Leg III: tarsi rv001110; metatarsi v02212, d002020; tibia v0122, d0220; patella pd3. Leg IV: tarsi v12; metatarsi v8; tibia v0223. Abdomen. Bilateral cover of fine hairs.Venter and dorsum with larger hairs; dorsum with anteriorly placed group of c. 30 long bristles.  Taxonomic note. May be confused with  M. maculosusfor which the male is unknown. Because of the maculate d abdominal colouration, arrangement of brown spots on venter, absence of spines on rd surface of metatarsi IV and littoral location consideration was given for this spider being the male of  M. maculosus(Rainbow & Pulleine, 1918). Because the 30Km distance and the intersection of Sydney Harbour separating the respective localities this spider is determined here a good species.   Etymology. The species is named in recognition of the author’s second daughter, Trang Wishart.   Distribution and natural history( Fig. 12C). This spider is known only from Sydney’s coastal suburbs north of Port Jackson. The burrow is unknown.  Fig. 6.  Misgolas trangae n.sp.( A–D) Ƌ, holotype AM KS49026. ( A), right palp retrolateral.
