Material examined. Holotype: ♂, INDONESIA, Maluku Province: Aru Islands ( MSNG, examined). Original label: / Storena zebra Thor. ; Aru Islands , Vakan, O. Beccari/. New material. NEW GUINEA, Eastern Highlands: 1♂, Piunde-Aunde Camp , east slopes, Mt. Wilhelm , 3,600 m, Camp #5, 31–25 June 1959, 6th Archbold Expedition, leg. L.J. Brass ( AMNH); 1♀, Kimi Creek Camp, NE slopes, Mt. Michael , 1,980 m, Camp #9, 29 August – 13 September 1959, leg. J. Gunn ( AMNH). SOLOMON ISLANDS, Malaita Province: 20♂, 13♀ ( BMNH).

Remarks. The male of M. zebra conforms well with other males of the zebra -group in having: 1) a terminally bifid process on the TA; 2) a triangular apico-retrolateral fold directed mesad; 3) a large, triangular basal tooth. It can be differentiated by the partly split embolus ending in a divergent apex ( Fig. 447 View FIGURES 447–454. 447–454 ). The female spermathecae are short and stout, with secretory glands situated dorsally ( Fig. 452 View FIGURES 447–454. 447–454 ).

Natural history. The holotype of M. zebra was collected from a group of islands west of Irian Jaya. None of the islands are mountainous but most of them are covered in thick forests. Males were subsequently collected in the forests of noticeably high-altitude mountains (1,980 –3,600 m) of New Guinea as well as from the insular environment of Solomon Islands. Unlike other Mallinella species which are highly endemic to a particular locality, the distribution of M. zebra expands over 2,000 km in east-west direction.

Distribution. Indonesia (Aru Islands), New Guinea, Solomon Islands and northern tip of Australia.

Mallinella beauforti (Kulczy ń ski, 1911) comb. nov.

Storena beauforti Kulczy ṅski, 1911c: 430, pl. 19, figs 6–9, description of ♀

Material examined. Syntype: 1 juvenile: NEW GUINEA, Moso : 9–10 May 1903, no collector ( MIZ Inst. Zool. P.A.N. Warszawa, Coll. W. Kulczy ṅski ( MIZ 212007–212008 ), examined). Original label: / Storena beauforti ; Kulczy ṅski 1911 ; 1juv. SYNTYPUS; Nowa Gwinea: Moso; 9.–10.v.1903.; I.Z.P.A.N. Warszawa 46/51 U/.

Remarks. Kulczyṅski (1911c: 430) described female and male of Storena beauforti from the Lake Jamur region and Manikion of Dutch New Guinea. Unfortunately the male and female syntypes were confirmed missing by the museum curator (Dr. D. Mierzwa pers. comm.). Only one penultimate male (syntype) remains in the collection of MIZ but it was separately collected in Moso.

Lake Jamur is situated in the center of the narrow isthmus that separates the Bomberai and Vogelkop Peninsulas (Irian Jaya, Indonesia) from the remainder of New Guinea; the present-day Maniki was previously known as Manikion of the Vogelkop Peninsula (according to Dr. Ken Walker, Museum Victoria, Australia); Moso possibly corresponds with Muso ca. 30 km east of Jayapura.

Diagnosis. This species undoubtedly belongs to the genus Mallinella on the basis of the presence of cylindrical PVS in front of the spinnerets. Mallinella beauforti comb. nov. closely resembles M. vulparia sp. nov. in possessing a filiform embolus, and a similar shape of embolic base (see also Kulczyṅski 1911c: figs 6–7) but in the latter species the embolus is bifurcated, its mesal ramus is digitiform and short, whereas the embolus is entire in M. beauforti comb. nov. In the female type of M. beauforti comb. nov., the epigynal plate of is excavated on its anterior margin (Kulczyṅski 1911c: fig. 9), whereas in M. vulparia sp. nov. the epigyne is a broad trapezoidal plate ( Fig. 434 View FIGURES 434–439. 434 ).

Distribution. Indonesia, Irian Jaya, Vogelkop Peninsula.
