Description

As for the genus. Maximum male/female midbody width ca. 3.8 (mean of 24 males, range 2.9-4.7 mm)/4.8 mm (paralectotype female). Colour in alcohol: “Body reddish yellow with two broad, blackish, lateral longitudinal bands on the dorsum, separated by wide, reddish yellow median (band). Medial [longitudinal] stripe washed-out reddish, ventral flanks reddish-yellow” ( vittatus, Verhoeff 1924: 20   , my translation); “Trunk black, with brown legs and wide yellow reddish dorsal median band, significantly narrower than in vittatus   . Ventral flanks black” ( vittatus   dorsalis, Verhoeff 1924: 21, my translation); colour in types faded and patchy, dorsalis medial longitudinal band ca. 1/3 ring width, vittatus   ca. 2/3 ring width; colour and pattern variable in other specimens ( Fig. 4 View Fig C–I), but always with lighter colouring dorsally and darkest colouring on upper sides.

Male with transverse furrows shallow, narrow, sometimes indistinct. No longitudinal furrows laterally on diplosegments. Sternal lamella ( Fig. 2E View Fig ) with sides more or less straight, corners broadly rounded, distal margin a flat inverted V. Scopulae on legs 1 to 29, i.e., not present on last podous ring. Leg bases on rings 6 and 8 separated more widely than on other rings, sternites a little depressed. Anterior margin of aperture with rounded-triangular, medial extension and shorter, gently convex extension on either side (as shown in Fig. 3B View Fig for S. rubriventris   ).

Gonopods usually as for S. pruvoti   ( Fig. 10A View Fig ), but with femorite in some males thinner ( Fig. 10B View Fig ), and in other males shorter and bent medially near apex, and with medial femorite process larger, reaching to ca. 1/3-1/2 of solenomere length ( Fig. 10D View Fig ); intermediate forms occur ( Fig. 10C View Fig ).

Female with leg 2 coxa extended posteroventrally as apically rounded process (as shown for S. pruvoti   in Fig. 5 View Fig C–D).

Distribution

Forest and non-forest habitats in the Brisbane region, from Moreton Island ca. 130 km south to the Border Ranges, and inland ca. 80 km from the sea (map Fig. 12 View Fig ). Overlaps in range with S. pruvoti   and S. rubriventris   .

Taxonomic notes

The subspecies S. vittatus dorsalis   was erected for a single male only differing from S. vittatus vittatus   in size, colour of ventral flanks and width of the medial dorsal band. These three characters vary substantially in the 24 non-type males I have examined and do not appear to be correlated. I therefore regard the subspecies dorsalis as a synonym of the nominate subspecies vittatus   . The gonopod telopodites of the types are virtually identical ( Fig. 10E–G View Fig ).

S. vittatus   varies more across its range than other Solaenodolichopus   (described and undescribed), in gonopod form as well as in size and colour pattern. It might better be called ‘the S. vittatus   group’, and intensive sampling and genetic analysis across its range would be a worthwhile systematics project.

It is particularly interesting that the gonopods in S. pruvoti   and some S. vittatus   populations are indistinguishable, and that no colour pattern intermediates have so far been found. When redescribing S. pruvoti   as S. annulatus, Verhoeff   wrote: “Stands close to vittatus Verh.   (contribution 3, figs 9 and 10) but is distinguished by different patterning and some special features of the gonopods: the rudiment of the tibiotarsus [rounded process on basal side of U-shaped indentation] is smaller in vittatus   and not curved, the parsolenomere [apical tab] very similar but more transversely curved, the medial displacement of the solenomere is barely detectable, overall the solenomere is less curved and less clavate, the end in vittatus   rounded” ( Verhoeff 1941: 12, my translation). These small differences are largely contained within the variation seen in both S. pruvoti   and S. vittatus   . Until new diagnostic features are identified, S. vittatus   and S. pruvoti   are only separable on colour pattern.

Both Verhoeff and Mjöberg spelled the type locality of S. vittatus ‘Mt   Tambourine’, which in the early 20th century referred to both a village and to the small basalt plateau on which the village was located; the modern name for the plateau is Tamborine Mountain. Verhoeff (1924) did not give a collection date for the S. vittatus   types. Mjöberg’s unpublished field diaries show that he collected at ‘Mt Tambourine’ in the last two weeks of October 1912 (Å. Ferrier, in litt., 16 Dec. 2013; see also Ferrier 2006). The lectotype slide of S. vittatus   was labelled ‘lectotype’ by P.M. Johns in 1967, but Johns did not publish this lectotypification.

Verhoeff’s one specimen of S. vittatus dorsalis   was from ‘Glen Lamington’. Lamington Glen was a locality and rainfall recording station on the Lamington Plateau in the first half of the 20th century, and Mjöberg’s unpublished field diaries show that he collected on the ‘Lamington Plateau’ in mid-November 1912 (Å. Ferrier, in litt., 16 Dec. 2013; see also Ferrier 2006). The holotype slide was labelled ‘holotype’ by P.M. Johns in 1967.
