Succinctonotum frosti Gordon and Hanley , new species

Description. Male holotype. Length 1.4 mm, width 1.2 mm. Dorsal surface entirely shiny, lacking microsculpture. Color black except head reddish yellow ( Fig. 308 ), with black vertex, maculae consisting of narrow, yellow, sinuate vitta from clypeal apex adjacent to eye onto vertex, and short, yellow, median vitta from clypeal apex to midpoint of eye ( Fig. 310 ); pronotum with anterolateral angle reddish yellow; elytra with brownish red margin; antenna, legs yellow; mouthparts yellow except apical 1/3 of final palpomere brown; prosternal process brownish red; remainder of ventral surface brown with reddish tint except ventrite 5 yellow. Head punctures coarse, separated by a diameter or less; pronotal punctures smaller than head punctures, separated by a diameter or less; elytral punctures slightly larger than pronotal punctures, separated by a diameter or twice a diameter; prosternal, metasternal punctures large, separated by less than a diameter, punctures on abdominal ventrites 1, 2 large, separated by a diameter or less, punctures on remaining ventrites small, separated by about a diameter. Head with frons slightly more than ½ width of eye measured at vertex; eye canthus short ( Fig. 310 ); apical maxillary palpomere long, narrowed to apex in apical ½. Pronotum widest at middle, reflexed lateral margin narrow. Epipleuron flat, narrow. Prosternum short, as wide as long, as long as mesosternum, with apical margin nearly truncate, small anterolateral projection not setose. Postcoxal line on ventrite 1 short, arcuate, extended ½ distance to apical margin of ventrite ( Fig. 309 ). Apex of ventrite 5 narrowly, shallowly emarginate medially. Genitalia with basal lobe longer than paramere, slender, about equal in width from base to deeply emarginate apex; paramere slender, slightly narrowed from base to acute apex, weakly sinuate, dorsal margin smooth ( Fig. 311, 312 ); sipho lost.

Female. Similar to male except head not maculate, black, elytron bluish black ( Fig. 314 ); Spermathecal capsule curved medially, base enlarged, remainder of capsule slender ( Fig. 313 ).

Variation. Unknown.

Type material. Holotype male; PANAMA: BarrowColoIsl. ( Barrow Colorado Island , CZ (Canal Zone), Feb. 11–1929. ( USNM).

Other specimen. 1. Female differing from male described above by length 1.3 mm, width 1.1 mm ; immaculate head; distinctly blue elytra; and prosternal process medially depressed. Genitalia typical of Cephaloscymnini , spermathecal capsule lost. Label data: COSTA RICA: Heredia Est. Biol. La Selva , 50–150m 10o 26'N 84o01'W, Prov. ALAS, INBIO–OET, M/06/021, 02 Marzo 1983, Bosque primario. ( USNM) .

Remarks. These specimens are distinguished from other known Cephaloscymnini by the generic characters. The female listed under “other specimen” above is not designated as a type because it may not be conspecific with the male holotype. It matches the holotype in all characters other than those described above.

Etymology. This species is named for S. W. Frost, collector of the holotype.
