Etymology
Johnson ms name, presumably from the Latin ‘ seditiosus ’, meaning ‘mutinous’ or ‘fractious’.
Material examined
Holotype
JAMAICA • ♂; St. Ann Parish , 2.5 miles S of Moncague; 2250 ft a.s.l.; 3 Apr. 1968; forest floor litter; S. Peck and R. Fiske leg.; parts of antennae missing; FMNH.
Paratype
JAMAICA • ♂; same collection data as for holotype; aedeagus glued to card, antennae missing; MMUE.
Description
SIZE. Habitus ( Fig. 82A View Fig ), length 0.83 mm.
COLOUR. Yellow brown, head darker, pubescence, legs and antennae dusky yellow.
HEAD. With a shallow linear depression behind the eyes, width across eyes 0.21 mm; mentum parallelsided; antennomeres III–XI, length 0.39 mm, III–IX length 0.22 mm, X–XI length 0.17 mm. (Note; one antennomere missing, the other missing antennomeres III–IX, X–XI remaining pasted to the card).
PRONOTUM. 0.26 mm long, 0.37 mm wide, densely pubescent, the hairs barely overlapping, and foveolate, without basal foveae; sides rounded, becoming almost parallel to acute hind angles, bordered, the border continuing along the posterior margin to the short and angulate median emargination in front of the scutellum ( Fig. 82B View Fig ).
ELYTRA. 0.49 mm long, 0.40 mm wide, pubescent and foveolate contrasting with the pronotum.
MESOVENTRITE. Medial extension of collar short, parallel-sided then becoming effaced; mid-keel parallelsided hind angles with short flat carinae to mesocoxal anterior borders, rising medially with transverse foveolate sculpturing and ± eight setae (missing from holotype) to a point above the keel; keel with ± six setae, short, terminating in a point at the mid-point of the mesocoxae; mesoventral lateral margins evenly rounded, without serrations; humeri toothed ( Fig. 82C View Fig ).
METAVENTRITE. Length 0.15 mm, reticulate at sides, depressed disc with crescent-shaped foveolae and mixture of setae and elongate scales, distance across spines 0.12 mm.
WINGS. Apterous.
GENITALIA. Male aedeagus pointed, lateral margins broadening towards tip.
Remarks
Distinguished from C. insulare sp. nov., the only other Cissidium reported from Jamaica, by the acute hind angles of the pronotum.
