Turdinirmus australissimus Gustafsson & Bush

new species

Turdinirmus australissimus Gustafsson & Bush  , new species

( Figs 189–195View FIGURES 189 – 190View FIGURES 191 – 195)

Brueelia daumae ( Clay, 1936)  ; Green & Munday 1971: 8 (partim).

Type host. Zoothera lunulata lunulata (Latham, 1802)  —olive-tailed thrush. Type locality. Pass River, King island, Tasmania, Australia.

Diagnosis. Turdinirmus australissimus  n. sp. is similar to other Turdinirmus  species from Zoothera  spp., particularly Tu. daumae  , with which it shares the broad head carinae and large head nodi. However, in Tu. daumae  the marginal carina is narrowly and obliquely interrupted lateral to the dsms, whereas in Tu. australissimus  ( Fig. 191View FIGURES 191 – 195) the dorsal preantennal suture does not reach either dsms or the lateral margin of the head. The dorsal anterior plate of Tu. daumae  is shorter and more oval than in Tu. australissimus  , and the frons of Tu. daumae  is more gently rounded, and not flattened as in Tu. australissimus  ( Fig. 191View FIGURES 191 – 195). Vulval chaetotaxy is overlapping between the two species, but Tu. daumae  generally have 7–9 marginal setae on each side (5–7 in Tu. australissimus  , Fig. 195View FIGURES 191 – 195). The male genitalia of Tu. daumae  are similar to those of Tu. australissimus  ( Fig. 192View FIGURES 191 – 195), with the proximal mesosome being more or less flat in both species, but the mesosome is even shorter in Tu. daumae  , with posterior margin being more or less parallel to anterior margin, and not strongly convergent as in Tu. australissimus  ( Fig. 193View FIGURES 191 – 195). The lateral corners of the lobes are even more acutely angular in Tu. daumae  than in Tu. australissimus  , and the papillate submedian section is more extensive, and reaches more than half of the width of the lobe (not less than a third as in Tu. australissimus  ). Parameres distorted in all specimens examined of Tu. daumae  , but appear to be similar to those of Tu. australissimus  ( Fig. 194View FIGURES 191 – 195).

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 191View FIGURES 191 – 195. Dorsal preantennal suture does not reach dsms. All head carinae and nodi very broad. Thoracic and abdominal segments as in genus description and Figs 189–190View FIGURES 189 – 190.

Male. Abdominal chaetotaxy as in Table 2 and Fig. 189View FIGURES 189 – 190. Basal apodeme somewhat constricted at mid-length ( Fig. 192View FIGURES 191 – 195). Proximal mesosome concave to flat; whole mesosome very short. Gonopore ( Fig. 193View FIGURES 191 – 195) as a wide, angular thickening that converge medianly; open distally and proximally. Mesosomal lobes much wider than long, angular, with thickened margins and papillate section submedianly; 2 pmes near distal end of each lobe, at least 1 typically submarginal. Parameral heads ( Fig. 194View FIGURES 191 – 195) bluntly bifid. Parameral blades small; pst1–2 as in genus description. Measurements ex Zoothera lunulata lunulata  (n = 2): TL = 1.89; HL = 0.48–0.50; HW = 0.52–0.54; PRW = 0.32; PTW = 0.43–0.45; AW = 0.57.

Female. Abdominal chaetotaxy as in Table 2 and Fig. 190View FIGURES 189 – 190. Subgenital plate roundedly triangular, with narrow median section approaching vulval margin ( Fig. 195View FIGURES 191 – 195). Vulval margin gently rounded, median section concave ( Fig. 195View FIGURES 191 – 195); 5–7 short, slender vms on each side, and 7–11 short, thorn-like vss on each side; 3–5 long, slender vos on each side; distal seta median to vss. Measurements ex Zoothera lunulata lunulata  (n = 4): TL = 1.96–2.21; HL = 0.49– 0.55; HW = 0.53–0.61; PRW = 0.31–0.35; PTW = 0.44–0.48; AW = 0.61–0.68.

Etymology. The species epithet is derived from Latin “ australis  ” for “South”, with the superlative ending “- issimus ”, and refers to the southern type locality of the species, the most southern of all species in the Brueelia  - complex to date (with the exception of species introduced by human agency), and one of very few known from Australia.

Type material. Ex Zoothera lunulata lunulata  : Holotype ♂, Pass River, King Island, Tasmania, Australia, 21 Feb. 1968, R.H. Green, Brit. Mus. 1975-81 ( NHML)  . Paratypes: 1♂, 3♀, same data as holotype ( NHML)  ; 2♂, 3♀, Flinders Island , Tasmania, Australia, 21 Mar. 1966, R.H. Green, Brit. Mus. 1968-752 ( NHML)  .
