29. Dilatitibialis florence Canepari and Gordon , new species

Description. Male holotype. Length 2.5 mm, width 2.0 mm; body rounded, slightly elongate, convex. Dorsal surface smooth, shiny except pronotum feebly alutaceous, shiny. Color black except head yellow, pronotum with black basomedian macula extended 2/3 distance to anterior margin, apex of macula deeply, narrowly emarginate with yellow; elytron with 4 small, yellow spots, 2 basal spots, 1 discal, 1 lateral spot narrowed medially, scutellar spot irregularly rounded, discal spot irregularly triangular on both ends ( Fig. 157 ); ventral surface with antenna, mouthparts, prothoracic hypomeron and legs yellow; abdomen yellowish brown medially, lateral 1/4 and ventrites 5-6 brownish yellow. Head punctures small, separated by a diameter or less, each puncture about as large as an eye facet; pronotal punctures slightly larger than head punctures, separated by 1-2 times a diameter; elytral punctures as large as on pronotum, separated by 1 to 4 times a diameter; metaventral punctures lacking medially, smaller than elytral punctures near middle, separated by twice a diameter, coarser, separated by about a diameter toward lateral margin. Clypeus apically truncate, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin rounded, basal margin with trace of bordering line. Epipleuron narrow, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, flange wider than remainder of protibia, outer margin curved, smooth, sponda distinctly extended beyond protibial flange. Carinae on prosternal process narrowly separated at apex, convergent toward base, joined at basal 1/4 with single carina extended to basal margin of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4-5 small, extended under apical 1/4 of 4th ventrite; postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, extended forward, ventrite with sparse, short pubescence and large, dense punctures medially; ventrites 2-4 pubescent throughout, punctures large medially, small, dense, becoming denser toward lateral margin; 5th ventrite coarsely, densely punctured in basal 2/3, apical 1/3 depressed, feebly depressed by primary pore laterally, without tubercle on each side of middle, apical margin broadly, weakly emarginate; 6th ventrite short, narrow, depressed medially, apical margin broadly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface feebly punctured. Apical tergite with apex weakly rounded. Genitalia with basal lobe short, wide, 3/4 as long as paramere, asymmetrical, sides weakly rounded, apex rounded; paramere wide, curved, Psc, apex with small, ventral projection, trabes straight ( Fig. 158, 159 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, sinuate, apex rounded, outer arm about as long as inner arm, with accessory piece, basal border broadly, weakly emarginate ( Fig. 160, 161 ).

Remarks. Dilatitibialis connie and D. florence are similar in nearly all regards except for differing dorsal color patterns. The latter species is also distinguished by a metaventrite impunctate medially, and with punctures in lateral 1/2 small, separated by about a diameter. The elytron of D. florence has a long, narrow lateral spot in the apical 1/2, but this spot probably represents a connection of the mediolateral and apical spots. These species may be synonymous, but are here treated as valid because of these differences, see remarks under D. connie ..

This species named for Claudio Canepari’s wife, Florence, in recognition of her long standing patience with entomological matters.
