is recognized as a member of Alycaulini in possessing the enlarged dorsal-longitudinal ridges on the basal half of the ovipositor and the sclerotized and setose
posterior margin of the male seventh tergite, diagnostic characters of the tribe.
Habitus (Figures 21-22): Head brownish red; compound eyes black, rounded, arranged transversally; vertex smooth, rectangular, with a prominent median carina; ocelli closer to each other than to compound eyes; tylus smooth and rectangular with a prominent median carina; antennae brownish red, pedicel sparsely setose
, basal body of flagellum ovoid with one arista as long as pedicel; postclypeus brownish red, inflated, angulose in profile, with one longitudinal carina strongly marked and prominent, lateral grooves strongly marked; rostrum extending to mesocoxae.
All species are large to very large, highly setose
and dark brown to black in color (Figs.
17) with basal piece 0.6 times total length; median lobe 0.5 times total length, with dorsal midline carinate, midlength with lateral wings up-curved and retrose; paramere 0.6 times total length, gradually broadening and dorsoventrally compressed apically, apex obliquely subtruncate, densely setose
dorsally and ventrally; ventrally separate, articulate.
2C, D) with all articles distinct, larger anteriorly; carpi sparsely setose
on anteromedial corners; all propodi enlarged, each produced into proximal lobe with socket receiving tip of reflexed dactylus; long sharply pointed dactyli on pereopods 1-5, shorter and blunter dactyli on pereopods 6-7.
Thorax: Dark red-brown to black, extensively dull gold pruinose, orange and pale yellow-white setose
. Mesonotum: Extensively pruinose with few small apruinose areas (small spot laterally anterior to transverse suture, V-shaped area postsuture).
Subgenital plate long, broad, setose
as illustrated (Fig.
Tergite-1 dorsally smooth, long, sparsely setose
at secondary tubercles.
Genitalia: Base of medial process of the pygophore laterally densely setose
Hypandrium small, fused on the sides to claspers; proximal halves of these, robust, setose
, distal halves slender, elongate, straight, preapically dilated, terminally acuminate (Fig.
