Prosopodesmus panporus
Blower and Rundle, 1980, male ex ANIC 64-000210. A Gonopods in situ, ventral view B Close-up of left gonopod tip, showing hairpad hp. Image contrast is low because specimen is uncoated. Scale bars: A = 0.05 mm, B = 0.01 mm.
Diagnosis.
Males with head + 19 rings, females with head + 20; adults ca 3.5-4 mm long; midbody metatergites typically with 3 transverse rows of 10-12 large tubercles; posterior portion of prozonite with small disks and microtubercles; ozopores on porosteles on all podous rings beginning with ring 5; gonopod telopodite bent posteriorly at midlength, lateral edge near tip with several rounded teeth.
Description.
The excellent description and illustrations of
Blower and Rundle (1980)
are reproduced below in Appendix 1. Here I add a few details:
Antennal sockets separated by ca 1X a socket diameter. Antennomere relative widths (5,6)>(2,3,4); relative lengths 6>5>(2,3,4). Head with vertex and frons microtuberculate; clypeus smooth, sparsely setose dorsally. Dorsal and lateral setae on collum, tergites and metatergites sparse, bisegmented, the tips flared and minutely toothed along distal edge. Anterior portion of prozonite with cellular structure, the cell walls with microvillose extensions (Fig. 2E; see also Fig. 3 of
Blower and Rundle (1980)
in Appendix 1); posterior portion of prozonite more or less uniformly microtuberculate, raised into low mounds each topped with a more or less round, convex disk 3-4X the diameter of a microtubercle. Limbus a thin, straight-edged lamella (Fig. 2E). Sternites as wide as long. Podomere relative lengths femur>(prefemur, femur)>(postfemur, tibia). 5+5 lobes along posterior edge of telson in male examined with SEM (including bilobed epiproct), rather than 6+6 as noted by
Blower and Rundle (1980)
. Spinnerets (the four prominent setae...housed in a collar at the apex of the telson of Blower and Rundle (1980, p. 29)) recessed in individual chambers, basal sheaths with unnotched distal edges.
Gonopore
midventral on leg 2 coxa, opening on low, truncate conical process. Prostatic groove ending in hairpad in posterior concavity of telopodite (Fig. 7).
Distribution.
So far known in Queensland from a single site in rainforest in the Iron Range Resource Reserve, ca 10 km northwest of Lockhart on the Cape York Peninsula (Fig. 8).
