description: Poecilipta janthina Simon, 1896
(Figs 3a, 98a, b, 100a–d, 135. Map 57)
Poecilipta janthina Simon, 1896: 408; Rainbow, 1911: 254.
Material. Queensland: holotype: ♀, "Cooktown", northeast Queensland, MNHN catalogue no. 18268, Boc. 1909, examined.
Other material. Queensland: 1♂, Davies Creek National Park, 23 Jul–26 Nov 1992, R. Raven, P. & E. Lawless, M. Shaw, QM S19845.
Diagnosis. The male differs from those of P. gloverae sp. nov. in the embolus being cylindrical almost through to the tip (Fig. 100a); females differ from those of P. kgari sp. nov. in the relatively longer spermathecae with a smaller head of spermathecae (Fig. 100d).
Description male QM S31517
Carapace 2.72 long, 1.68 wide. Abdomen 2.84 long, 1.36 wide. Total length 5.7.
Colour: carapace and chelicerae and ventral cephalothorax brown orange without dark markings; legs I and II yellow, femora I slightly darker; III, yellow with dark longitudinal stripes, IV dark brown; all tarsi pallid; abdomen dorsally dark brown with iridescent dark green sheen on scute; ventrally genital scute brown, abdominal scute paler flanks dark gray. Carapace: widest at coxae I and II, tapering strongly to narrow posterior margin only slightly wider than pedicel, anteriorly narrowing distinctly to long caput; fovea at coxae II and III, thorax slopes down from fovea and anteriorly arches gently to opposite widest point and slopes gently down to eyes and steeply across clypeus. Surface rugose with finely serrate lateral margins; fine white simple hairs around eye group. Clypeus ca. three AME diameters high. Fine ridge of cuticle separate below carapace above coxae. Eyes: front row slightly recurved, back clearly recurved and clearly wider behind than in front. AME ca. 2x ALE, ALE from in front set slightly lower; ALE, PME and PLE about same size. MOQ clearly longer than wide, slightly wider behind. Group occupies ca. 0.5 of headwidth. Chelicerae: small, convergent, vertical; strong inwardly directed bristle on each upper outer face; lobe indistinct; fang and furrow short; two small close teeth on retro margin; one large and one small basal on promargin. Maxillae: apically narrowed, divergent, short, with extensive pallid zone. Labium wider than long. Sternum: shield-shaped, anteriorly truncate and ventrally indented; posteriorly only extends to edge of coxae IV; small sclerotised triangular intercoxal extensions. Pedicel broad, arrow-like, with narrow anterior "spine". Legs: IV very long; femur IV distally unmodified, longer than abdomen and ca. 1.6 x femur III. Feathery hairs on I–IV, not on metatarsi I and II or any tarsi; all coxae with distinct triangular basal extensions. Trochanters with broad shallow notches. Tarsi slender, not curved or distally incrassate. Scopula absent; ventral tarsi with thick curved hairs. Brush of hairs ventrolaterally on metatarsi I and II = weak preening comb. Lateral coxae III rugose, less so on IV. Trichobothria: two rows on tarsi; long in basal group on metatarsi; basal short on tibia. Spines: I: fe pv1; pa 0; ti v2.2.2; me v2.2. Tibial spines long curved, erect and overlapped longer than on metatarsi, long but contiguous. II: fe d1; pa 0; ti v2.2.2; me v2.2. III: fe p2d3; pa d1 (distal); ti p2r1v2.2.2; me p2r2v2.2.3. IV: fe p1d2r1; pa d1 (distal) ti p2r2v2.2.2; me p3r3v2.2.3. Palp: fe p1d2; pa (weak) p1d2; ti p2d1r1; no strong spines ventrally on palpal femur. Abdomen: two long anteriorly directed bristles from front face of dorsal scute, which from front to just past widest point, i.e., a small crescent over spinnerets not covered scute narrow, widens slightly then with distinct dorsal (vertical) widening, hair cover simple; cuticle finely pustulose. Ventral scute surrounds pedicel with narrow dorsal collar, medially indented with two small lateral lobes, laterally arcs down to cover booklungs and genital area; main ventral scute long, rectangular, from just behind genital plate widening slightly, then constricted and fused to tracheal spiracle. Pedicel with short collar. Palp: tibia short, with truncate flared ventral collar; cymbium long with small basal margin and truncate ventrolateral process above that; retrolateral edge intrudes over bulb. Tegulum pyriform with lateral excavation and subtegulum, apically forms corkscrew tip to embolus.
Holotype female MNHN 18268, as ♂ except as follows:
Colour: carapace, legs and abdomen yellow orange without pattern (?faded); narrow slightly darker dorsal scute extends for ca. one-fifth. Carapace: margin smooth, not iridescent; pile of fine hairs. Chelicerae: no enlarged fang setae. Legs: femur IV unmodified. Feathery hairs absent. Spines: erect bristles on ventral edge of femora I–III. Palp: fe: p1d2v4; pa p1d1; ti p2r1; ta v2 distal. I: fe p1 long d3; ti v2.2.2(2.2w); me v.2.2. II: fe d3; ti v2.2.2; me v2.2. III: fe p3d3r1; pa d1; ti p2r2v2.2; me p2r2v2.2.3. IV: fe p1d3r1; pa d1w; ti p2r2v2.2.2; me p2r2v.2.3. Epigyne: two small lunate ridges dorsally shield insemination duct passing forward and recurving twice before joining long central spermathecae.
Distribution and Habitat. Known only from heathland forest west and north of Cairns, north Queensland.
Remarks. As in the descriptions of Supunna funerea and S. versicolor, Simon (1897a) first listed Poecilipta as a new genus in the Histoire Naturelle des Araignées although he had already included species in the then undescribed genus (Simon, 1896).
