Megalopsalis Roewer 1923 View in CoL

Macropsalis Sørensen 1886: 54–55 View in CoL non Sclater 1866 — Pocock 1903a: 398; Hogg 1910: 277; Roewer 1911: 102, 1912: 278. Megalopsalis Roewer 1923: 866 View in CoL (replacement name for Macropsalis Sørensen View in CoL )— Forster 1944: 184–185 (referring to material of Forsteropsalis View in CoL new genus); Crawford 1992: 28, 29.

Type species. Macropsalis serritarsus Sørensen 1886 by monotypy.

Other included species. Megalopsalis epizephyros View in CoL new species, Megalopsalis eremiotis View in CoL new species, Megalopsalis hoggi Pocock 1903a View in CoL , Megalopsalis leptekes View in CoL new species, Megalopsalis pilliga View in CoL new species.

Diagnosis. Megalopsalis is distinguished from Pantopsalis , Forsteropsalis , Spinicrus and Neopantopsalis by the presence of a well-developed apophysis, longer than wide, on the pedipalpal patella. It differs from Monoscutum , Acihasta , Templar and Australiscutum in having long, slender legs and from Hypomegalopsalis and Tercentenarium in the presence of elongate chelicerae in the male. It also differs from Tercentenarium in having a short glans that is triangular in ventral view.

Description. MALE. Dorsal prosomal plate denticulate; remainder of dorsum unarmed. Chelicerae elongate, heavily denticulate; cheliceral fingers closing tightly against each other. Pedipalpal patella with well-developed hypersetose mediodistal apophysis; claw with ventral tooth-comb. Trochanters I and II usually with prolateral spines (except in Megalopsalis leptekes ). Femora I and II denticulate, femur I usually particularly so; patella and tibia I often denticulate. Penis with elongate shaft and long tendon; well-developed bristle groups at shaft-glans junction. Glans short, triangular in ventral view, bent only slightly dorsad from glans; dorsal side evenly convex, no dorsolateral keel; distal end of glans dorsoventrally flattened. Pores on glans shallowly or deeply recessed without distinct rim. Spiracle with anterior grill of slender spines, often only extending partway across; spines often reticulate (except M. leptekes ), with simple or palmate terminations; cluster of lace tubercles present at lateral corner; posterior margin of spiracle unornamented.

Distribution (fig. 44). Southern Western Australia, southern South Australia, Victoria, eastern New South Wales.
