Fig. 10, 11  
 Description of holotype. Male, length 5.50 mm. Color of head dusky, dark chestnut above, vertex and underside orange; mandible paler with black apex. Prothorax and procoxae orange. Mesosternum and mesocoxae chestnut. Elytra ochreous, costae and sutural border orange, apical third suffused with black. Antennal segments I–IV blackish, the rest chestnut. Legs (including metacoxae) sepia-black. Head with frons, clypeus and mandibles densely, and somewhat rugosely micropunctate; with inconspicuous, dense, recumbent, white pubescence. Vertex glabrous; with rugose, small, dense alveolate punctures. Antennae eleven-segmented, passing middle of elytra by half a segment. Basal segments moderately pubescent, towards apex denser. Antennomeres III–V subcylindrical, weakly widened at apex, III and V (0.4 mm) slightly longer than IV (0.35 mm); VI widening from base to moderately tumid apex, of equal length to V; VII and VIII moderately serrate; IX and X somewhat oval; VII (0.35 mm); VIII and IX (0.30 mm); X (0.25 mm); XI (0.35 mm) slightly shorter than III, fusiform and narrow. Prothorax subcylindrical; 1.4 longer than wide (0.95 mm); widest at middle; sides widened, distinctly rounded for middle third, moderately attenuate, bisinuate to front margin, strongly bisinuate to base (width of base 0.90 mm, about 1.3 narrower than humeri). Pronotum lacking setae; surface smooth with somewhat silky appearance; latero-basal gibbosities rather large, but rounded at apex. Elytra glabrous (except for inconspicuous pubescence at apex); moderately sinuous at sides, narrowest well before middle; distinctly depressed at base and on disc. Dorsal costa strong, almost reaching apex. Surface not microreticulate, across middle half ornamented with large, deep, alveolate, contiguous punctures in four seriate rows. Margins not asperate. Elytral apices well rounded. Legs with peduncle of femora distinctly sulcate. Metafemora passing apex of elytra at base of clave. Metatibiae sinuate. Apex of protibia with angular projection laterally. First segment of metatarsus longer (0.55 mm) than the following two combined (0.40 mm).   
 Male variation. In two specimens orange color as in holotype, in four more rufous, in one brownish; in one specimen head above rufous-orange, the rest similar to holotype; in three specimens legs black, sepia in two, chestnut in two. In two males surface of pronotum weakly rugose, with larger, semi-evanescent punctures on center of disc, the rest as holotype. In one male antennae pass apex of elytra by half a segment, in one by one segment, in two by 1.5 segments, in three by two segments. In two of the smallest males elytral punctures subseriate, smaller, and shallower.   
 Female (Fig. 11). Very similar to male; orange color more rufous than holotype, often clouded dusky; in two paratypes head above black, in two rufous-orange, in four only vertex rufousorange; antennal color entirely black in six females, as holotype in two; in four females legs black, sepia in four. Surface of pronotum weakly rugose, with large, semi-evanescent punctures on center of disc. Antennal proportions much as male, but more crassate, base of antennomeres as wide as or wider than mesofemoral peduncle (when viewed from the side). In larger females prothorax 1.2 longer than wide and less sinuate at sides. Elytra more sinuate at sides; and usually narrowest well before middle. Metatibiae less sinuate. Side of protibial apex as in male. First segment of metatarsus 1.0–1.2 longer than the following two combined. Punctures on middle half of elytra as male; but, in the single, unusually large, female with five rows, and sides of humeri with distinct, small, tooth-like projection laterally (just traceable in most larger specimens of both sexes).   
 Measurements (mm). 8 males / 8 females, total length 4.75–6.00/5.30–7.70; length of pronotum 1.10–1.45/1.30–1.75; width of pronotum 0.80–1.00/0.90–1.40; length of elytra 2.90–3.95/3.30–4.60; width at humeri 1.00–1.25/1.15–1.30.   
 Diagnosis. This species, with eleven-segmented antennae, may be immediately recognized by its unusual color combination; dusky head, pale orange prothorax, ochreous elytra (with dusky apex), and sepia colored appendages. Moreover, the margins of elytra of D. dilmanappae are not asperate, a character only shared by Dihammaphora nitidicollis Bates, 1870 among the eleven-segmented species. The latter is readily separated from D. dilmanappae by its black color, with prothorax reddish, and club of femora reddish black.   
 Type material. Holotype, male: BOLIVIA, Santa Cruz, 17°29’96"S/ 63°39’13"W, 430 m, 5 km SSE of Buena Vista, Hotel Flora & Fauna, flying to/on flowers of “ Turere ”, 9.X.2004 (MNKM). Paratypes with data as holotype, 2 males and 2 females, (RCSZ); 7.X.2005, male and female (DZUP), male (FSCA), female (MNKM), male and female (MZUSP), male (RCSZ), male and female (USNM). Paratypes with same data as holotype, different host flower, flying to/on flowers of “Bejuco hoja lanuda”, 30.IV.2005, female, 5.V.2005, male (RCSZ); flying to/on flowers of “Sama blanca chica”, 21.X.2006, male, 27.X.2006, female (RCSZ).   
 Comment. Another character not observed in any of the species described here, nor mentioned by Napp and Mermudes (2010), is found on the mesosternum, where the surface is divided into flat patches of dense pubescence by rings (in males), or partial rings (in females) of smooth glabrous chitin. This character was not confirmed for the description of the holotype because the mesosternum was hidden by the specimen’s mount.   
 Etymology. This species is named in honor of Dr. Dilma Solange Napp, now retired from the DZUP; she will be missed.
