Diagnosis. Ulivellia laetitiae differs from all the other species of the genus in that the subbasal band does not continue on the alula, the discal band is more arched than in U. inversa and crossvein dm-m is basally bent in the apical fourth (Figs 4 C, 53 A, B, F).
Description. Female. Head (Figs 53 E, F) ratio (length: height: width) 1: 1.4: 1.5, mostly black, except lower half of frons, gena and parafacial brownish brown. Frons 0.7× longer than wide (measured from ptilinale fissure to fore ocellus), orange brown with black ocellar triangle and vertical plates; orbits silver-white microtrichose, brown. Parafacial narrow, 0.2–0.3× broader than postpedicel, slightly white microtrichose. Frontal setulae relatively short, black, inclinate and partly proclinate, forming two irregular rows of 3–6 setulae on each side, all more than ⅓ and up to ½ the length of ocellar setae; 2 orbital setae, posterior longer than anterior, about 0.5–0.6× longer than inner vertical seta and 3–4× longer than outer vertical seta; postocellar 0.3× longer than inner vertical setae; outer vertical seta short, 0.2–0.25× longer than inner vertical seta and barely distinguishable from postoculair setae forming one row allied by 9–12 dorsal and 10–15 ventral occipital setae. Lunule very narrow, indisctinct, orange-yellow. Eye 1.6× higher than long. Face (above suture) as high as wide at transverse fold, brown, obscured ventrally, densely white microtrichose; epistome brown to black, sparsely white microtrichose, metallic shiny, often with greenish or cyan shine, strongly produced anteriorly and separated from upper part of face by deep suture. Clypeus brown to black, sparsely white microtrichose, metallic shining, often with cyan sheen, 0.3–0.4× higher than epistome. Gena brownish yellow, with long genal seta and 3–4 additional setae anterior of it, 0.5–0.8× longer than genal seta. Occiput black, except postgena brown, with silvery to cyan metallic sheen, moderately densely covered with white microtrichia partly hiding underlying cuticle; ventral part of occiput (postgena) with 4–5 setae almost as long as genal seta. Antenna brownish yellow; scape and pedicel with black setulae; postpedicel brown, blackish antero-dorsally, whitish microtrichose, 1.9× longer than wide, narrowed in apical half and rounded; arista black except yellow at base, almost bare. Mouthparts black, prementum black, shiny. Palp yellowish-brown, with black setulae, ventrally and subapically with setulae 2–3 times longer.
Thorax (Fig. 53 F) black, metallically shiny with yellowish-green or cyan sheen and sparse yellow microtrichia not obscuring underlying cuticle. Mesonotal scutum 1.4× longer than wide; with 3 almost inconspicuous yellowish-green vittae in otherwise silvery cyan sheen in the presutural area, postsutural area with yellowish-green shine, black setulose, with 8–10 rows of setulae between dorsocentral setulae; 1 pair of acrostichal setae; prescutellar area without setulae. Scutellum dorsally flattened, posteriorly black or brownish, finely shagreened, sparsely microtrichose, without setulae. Subscutellum subshining, black with yellowish -green metallic sheen. Mediotergite shining black with metallic yellowish-green sheen, sparsely microtrichose. Set of setae normal for the genus. All the setae and setulae black. Anepisternum apicoventrally with yellowish-green sheen, as well as anepimeron ventrally and katepisternum nearly entirely, pleurae otherwise with metallic silvery cyan sheen.
Wing (Figs 4 C, 53 F) 5.8–6.6 mm (♂) 6.2–6.8 mm (♀) long: 2.3–2.5× longer than wide, basicostal cell hyaline; costal cell long, 4.8× longer than wide, brown in basal third, with costa almost straight, forming neither lobe nor cleft; pterostigma entirely brown, narrow triangular, 5.1× longer than wide, vein R 1 setulose dorsally at pterostigma level, ending at level of crossvein dm-m; vein R 2+3 at apex bent anteriorly and then subparallel to costa, turning towards it before very apex; vein R 4+5 arcuate, first upward from crossvein r-m and downward distally, terminating just shortof wing apex; vein M 1+2 similarly curved but in opposite direction, terminating well beyond wing apex; crossvein r-m at basal ¼ of cell dm; crossvein dm-m bent basally in the apical fourth. Cell r 4+5 4.5–5.5× longer than wide, broadest just beyond the middle and narrowed apically; Cell m1 narrowly triangular; ultimate section of M 1 2.4×. as long as crossvein dm-m and 1.9× longer than penultimate section. Vein CuA slightly convex in upper part, cell cua with short posteroapical lobe along vein CuP. Wing pattern similar to U. inversa and U. amnoni, subbasal band broader and more or less oblique, not continued on alula, discal band strongly arched, stronger than in U. inversa and U. amnoni, broader at cell br and clearly narrowed at posterior end, preapical band slightly less arched than in U. inversa. Calypters white, with white ciliae. Halter creamy with yellow knob.
Legs (Figs 53 A–C) all entirely black bluish cyan sheen, femora partially with yellowish-green metallic sheen, except coxae ventrally and trochanters entirely yellow-brown and knees narrowly brown, all sparse with microtrichia except for coxae of prolegs. Mid tibia ventrally with one spur-like seta 3× longer than tibia width.
Abdomen (Figs 53 A–B) entirely black, tergites very finely shagreened and sparsely microtrichose, with metallic yellowish-green metallic sheen, less shiny than pleurae; setulae and setae black.
Male postabdomen. Sternite 8 setulose, with 2 longer setae. Cerci short oval, setulose (Figs 54 A–D). Epandrium ovoid, dorsally short, moderately setulose. Surstyli basally wide, inner surstylus with 10–11 prensisetae, outer surstylus simple with narrow, elongated, mesally directed ventral lobe apically bearing dorsally directed pimple-like process, but without distinct antero-ventral and postero-ventral lobes; inner surstylus with 12–15 thickened prensisetae (Fig. 54 D). Pregonites symmetrical, with 8–9 setulae ventro-mesally, conspicuously anterior of postgonites. Postgonites on laterobasal part of the phallic guide lobes, with 4–6 small trichoid sensilla. Phallus moderately short and narrow, about 3–4 times as long as epandrium high, almost bare, in rest coiled at right side of abdomen (Fig. 54 B). Ejaculatory apodeme short, bar-like, with relatively small sperm pump (Figs 52 D, 56 B).
Etymology. This species is named in honor of Laetitia Martina, the author’s girlfriend and mother of his children. The specific epithet should be treated as a noun in the genitive case.
Biology. All specimens were collected and many additional specimens were observed on mature stems of the bamboo Guadua weberbaueri, in contrast to many other species that were specifically attracted to freshly cut young shoots of the same bamboo species. This species appears to develop in the internodes of damaged mature stems of G. weberbaueri.
