TWO NEW VICTORIAN SYMPHYLA OF THE GENUS HANSENIELLA 9 
Hanseniella minor sp. nov. 
(Fig. 2, A-E.) 
Length. — 3-4 mm. 
Head . — About as broad as long, measuring in adult about O' 36 mm. in 
diameter. Clothed ■with numerous equally spaced setae, the largest lateral 
setae only a very little shorter than the breadth of the proximal antennal 
joints. “Central rod” exceptionally short and unforked. 
Antennae . — Maximum number of antennal segments counted in any 
adult 32; minimum 22. Setae on inner side of primary (“central”) whorls 
not longer than those on outer side. On first six segments four setae 
visible above. The secondary whorl begins on the lower side of the seventh 
and eighth segments, first appearing dorsally on about the fourteenth joint. 
A true third whorl, posterior to the second, does not develop ; there is, 
however, a whorl of diminutive setae from the eighth segment onwards, 
situated anterior to the primary whorl (Fig. 2a). The absence of a true 
third whorl, and the presence of this anterior whorl of small setae sharply 
distinguish the antennal segments from those of H. agilis (cf. Figs. 1a, 2a). 
The main setae of the primary whorl about equal in length, and about half 
the diameter of the basal antennal segments. On each segment from the 
second onwards, is a small sense-organ similar to that already described for 
H. agilis, except that the central spine is short, scarcely exceeding the others 
in length (Fig. 2b). Terminal segment of antennae with one large and two 
small stalked sense-organs, as in H. agilis. 
Scutes.— The first scute slightly convex on its posterior margin; from 
the third onwards they are slightly indented. A single pair of enlarged 
outwardly directed lateral setae on the fourth, seventh, tenth, thirteenth 
and fourteenth scutes. The enlarged seta of the second scute nearly twice 
the breadth of the basal antennal joints. 
Legs . — On the last leg the tarsus is nearly five times longer than thick. 
“Metatarsus” and tarsus each with five setae in the outer row. On the 
“metatarsus” the most distal is the largest, but is less than half the 
thickness of the “metatarsus.” The anterior claw (Fig. 2c) of the last 
leg slightly curved, and forming at its base a broad blade, which tapers 
less sharply than in H. agilis. Posterior claw very curved. It measures two- 
thirds length of the other. “Front seta” not exceptionally large, being a little 
than the posterior claw. Its basal half broad and blade-hke, its 
distal half tai>ering into a thin filament. . , , , , 
On the first leg the anterior' claw (Fig. 2d) is only slightly less curved 
than on the last leg, and the basal blade-like portion is less pronounced. 
Posterior claw gently curved and a little less than half the length of the 
anterior claw. Basal portion not as sharply demarcated as in H. agilis. 
“Front seta” robust and a little longer than the posterior claw. 
Cerci—(Fig 2e). Length from three to four times their thickness; 
soarselv clad with relatively large setae, of which there are not more than 
five in a row. They increase in length towards the apex, the largest hinder 
setae being twice the length of the smallest anterior setae. A single 
enlarged seta at the apex itself, about equal in length to the thickness of 
the cercus at its base. 
Habitat.— As for H. agilis. 
Type in National Museum, Melbourne.
