Diagnosis. Cryptodacus univittatus is most similar to C. tigreroi and runs to that species in the key of Norrbom (1994). It differs in the shape of the aculeus tip ( Figs. 35-36 ), which is much more slender and elongate triangular than in C. tigreroi ( Figs. 31-32 ). The subapical band anterior to vein R4+5 and the apical band are orange and poorly defined in C. univittatus ( Figs. 20-21 ), whereas they are dark brown and well delimited in C. tigreroi ( Fig. 18 ). Syntergite 1+2 is mostly dark brown in C. univittatus (white only narrowly on posterior margin medially), whereas in C. tigreroi there is a white band on the posterior half except on the lateral margin, and C. univittatus also lacks the brown genal spot that is present in C. tigreroi. The first flagellomere also is slightly shorter in C. univittatus , 4.25–5.00 times as long as wide, versus 5.67 times as long as wide in C. tigreroi.

Description. Length 4.0–5.0 mm. Wing length 3.65–3.9 mm, width 1.5–1.6 mm.

Head ( Figs. 9–10 ): Mostly yellow. Frons with dark brown band across vertex, medially extending anteriorly to include ocellar tubercle, sometimes with grayish or faint brown markings connecting frontal setae and/ or extending from brown band to anterior orbital seta. 2 or occasionally 3 frontal setae (third (posterior) seta strong in only 1 specimen, weak in 2 others), 2 orbital setae, well separated, distance between them 1.63–2.46 times distance from anterior seta to eye margin. Ocellar seta weak, 1–2 times length of ocellar tubercle. Gena entirely yellow. Occiput and postgena dark brown except dorsal and anterior margins, brown area almost reaching postocular setae. Face ( Fig. 9 ) with ventral margin strongly concave, 0.47–0.56 times as high (measured medially) as wide (measured between ventral corners), with 4 dark brown spots arranged nearly in square, lateral margin often narrowly brown, sometimes connecting to dorsal spots, gray spot similar in size to brown spots sometimes present near lateral corner on ventral margin. Clypeus and prementum dark brown, palpus yellow to pale brown. Antenna with scape and pedicel yellow, first flagellomere pale to moderate brown, elongate, 4.25–5.00 times as long as wide, apex flattened, in lateral view rounded and often slightly expanded. Arista short pubescent.

Thorax ( Fig. 8 ): Mostly dark brown, with following whitish markings: Postpronotal lobe; band on transverse suture (interrupted medially), across posterior part of notopleuron and posterior margin of anepisternum, almost reaching katepisternum; dorsomedial spot on katepisternum aligned with band on anepisternum but slightly wider, extending to or almost to katepisternal seta; single medial and paired sublateral vittae on scutum, medial vitta short, not reaching level of band on transverse suture anteriorly, extending to acrostichal seta posteriorly, lateral vitta narrowly separated from or often connected (8 specimens) to band on transverse suture, including base of intra-alar seta and extended to posterior margin of scutum; scutellum except base of disk, sides entirely white. Scutum entirely microtrichose, with denser submedial vitta from middle of presutural part to anterior end of medial white vitta. Chaetotaxy normal for genus, postpronotal, 2 notopleural, 1 anepisternal, anepimeral, katepisternal, postsutural supra-alar, intra-alar, postalar, acrostichal, and 2 scutellar setae well developed. Presutural supra-alar seta relatively small, half to two-thirds size of postsutural supraalar seta. Dorsocentral seta also relatively small, aligned one-third to two thirds distance from postsutural supra-alar seta to postalar seta. Legs with coxae, most of femora, and hind tibia dark brown; trochanters and sometimes bases of femora yellow to pale brown; apical third to half of fore femur and apex of mid femur white; apex of hind femur often white or yellow; apex of hind tibia often yellow; other tibiae and tarsi yellow.

Wing ( Figs. 20–21 ): Crossvein r-m 0.69–0.73 distance from bm-cu to dm-cu. Pattern including: brown and orange discal band covering most or all of cell bc, cell c and pterostigma, curving posteriorly to cover cell r1 posterior to pterostigma, base of cell r2+3, apex of cell br and crossvein r-m, most of apex of cell dm (although small subapical hyaline area present in that cell anteriorly), and apex of cell cu1, band dark brown anteriorly, distinctly paler orange or orange brown in cells r1, r2+3, and br except for dark brown margins, and moderate brown posteriorly; brown area covering cells bm and bcu and bases of cells dm and cu1, sometimes extending narrowly along vein Cu1 to connect with discal band; narrow brown subapical band covering crossvein dm-cu, broadly connected to discal band posteriorly, paler and diffuse anterior to vein R4+5; and weak, diffuse orange apical band, usually connected anteriorly to subapical band but sometimes largely absent in cells r1 and r2+3.

Abdomen ( Fig. 8 ): Dark brown except narrow white medial vitta from posterior margin of syntergite 1+2 to apical margin of tergite 6. Tergites nonmicrotrichose except anterior third, anterolateral two-thirds, and medially on syntergite 1+2, anterior margins of other tergites, and sometimes very narrowly medially (middle of white vitta) on tergites 3 and 4. Setulae acuminate, black.

Female terminalia: Oviscape dark brown, sometimes apex orange ventrally, 0.92–1.10 mm long, stout but without strong dorsal hump. Aculeus ( Fig. 35 ) (n=1) 0.86 mm long, tip ( Fig. 36 ) (n=4) slender, elongate triangular, 0.13–0.15 mm long, apical 0.055–0.070 mm sagittate, triangular, 0.04–0.05 mm wide, finely serrate. 2 spermathecae ( Fig. 37 ) subcylindrical with elongate base.

Distribution. Cryptodacus univittatus is known only from Panama.

Etymology. The name of this species is a Latin adjective referring to the single medial vitta on the abdomen.

Comments. Unless otherwise indicated, measurements were made on five specimens. All of the type specimens are females and were collected in McPhail traps. The male is unknown. McPhail traps have captured predominantly females of other species as well (the 3 type specimens of C. lopezi; the 44 type specimens of C. trinotatus ; and 5 of 7 specimens from Guatemala of C. tau ), perhaps indicating that females of this genus are more attracted to fermenting substances or simply disperse more than males.
