COPESTYLUM MEXICANUM (MACQUART, 1842) Larva and puparium: Posterior breathing tube shiny below TR. Above TR shiny and faintly punctured. AP about as long as TR is wide and with an incomplete and shallow longitudinal groove from spiracular plates to TR. Pupal spiracles slightly curved from the base and about 2¥ as far apart as pupal spiracle is long. Taxonomic notes: This species may be distinguished from others in the group by the AP which is about as long as TR is wide and the slightly curved pupal spiracles. Material examined: 1 ♂, one puparium MEXICO, Hidalgo, Metztitlán, 18.viii.2005 M. A. M. ex Opuntia sp.

COPESTYLUM IMITANS (CURRAN, 1926) Puparium: Anterior fold without extra large spicules. Anterior spiracles with three openings. Spicules only between longitudinal folds on the dorsum of the prothorax reaching to middle sensilla i.e. about halfway along folds. Abdominal vestiture of short, upright setae. Anal lobe with spicules. Posterior breathing tube orange, not tapering. AP smooth, mostly shiny and as long as TR is wide. Pupal spiracles dark orange, matt, and with three encircling rings of openings in upper third. Pupal spiracles about 1.5¥ as wide apart as a pupal spiracle is long. Taxonomic notes: Copestylum imitans is recognizable by the dark orange pupal spiracles, nontapering posterior breathing tube and numerous spicules between the longitudinal folds of the prothorax. Copestylum ornatum has similarly dark pupal spiracles but the posterior breathing tube tapers in that species.

COPESTYLUM MARGINATUM (SAY, 1829) Larva and puparium: Anterior fold with a wide spicule band extending from just above the antennomaxillary organs to the apex. Spicules extending almost to halfway along longitudinal folds of the prothorax, at least to beyond the middle sensillum on mid-dorsal folds. Crochets of metathoracic prolegs forming a w-shaped band. Metathorax with lateral folds bearing broad setae at sensilla 4 and 5. Anal lobe with broad setae. Posterior breathing tube with AP 1.6¥ length of TR, faintly coriacous otherwise shining and not tapering. Pupal spiracles (Figs 51, 53) about 1.3¥ length of AP. Taxonomic notes: Copestylum narginatum is most similar to C. limbipenne Williston, 1887, C. truncatum sp. nov. and C. simile Giglio-Tos, 1892 in having the AP the same length as or longer than the width of the TR.

COPESTYLUM FRAUDULENTUM (WILLISTON, 1891) Larva and puparium (prothoracic plate and pupal spiracles missing): Dorsal abdominal vestiture coating the surface but shorter on either side of the transverse folds. Ventral abdominal vestiture dense and of varying length across folds: anterior sides of folds with longer setae than posterior sides. Posterior breathing tube red-brown, surface corrugated and lightly punctured, about half width of puparium. TR deep and distinct. AP bulging, not tapering, about 0.77¥ as long as TR is wide and with spiracular openings of simple s-shaped curves. Taxonomic notes: The larva and puparium are readily distinguished from those of other species in this group by the clearly discernable TR on the posterior breathing tube and the dorsal abdominal vestiture which completely coats the integument. Material examined: 1 ♂, one puparium USA Arizona, Phoenix 12.ii.1939 collector unknown ex cactus (SI).

COPESTYLUM APICIFERUM (TOWNSEND, 1895) Larva and puparium (Fig. 25): Anterior fold with band of spicules rounded not tapered at outer limits. Longest vestiture of dorsum of prothorax shorter than longest spicules on the anterior fold. Posterior breathing tube about as long as wide above poorly defined TR (Fig. 66). AP tapering to half width of TR and 0.9¥ as long as TR is wide. Pupal spiracles separated by 2.1¥ their length and openings not clustered closely together at the apex but spread down the upper third and separated by about 2¥ diameter of an opening (Fig. 67). Taxonomic notes: Copestylum apiciferum is separated from C. quadratum (Williston, 1891) and C. milae sp. nov. by the pattern of distribution formed by spicules at the ends of the band on the anterior fold that are rounded not tapered, AP not as long as TR is wide and the distribution of the openings on the pupal spiracles, which are distributed over the apical third and not clustered at the apex. Copestylum apiciferum is separated from C. hidalgense sp. nov. by the absence of spicules on the anterodorsal margin of the mesothorax.

Pupal spiracles short, about 1.5¥ basal width, straight, shiny red with openings in upper third and separated by about 4.5¥ their length (Figs 48, 50). Taxonomic notes: Copestylum fornax is more similar to C. satur than to C. fraudulentum. It is distinguished from C. fraudulentum by the shallow TR and vestiture confined to medial areas of abdominal transverse folds. It is separated from C. satur by a redbrown, nontapering AP which is the same length as a pupal spiracle, the shorter, 1.5¥ basal width pupal spiracles which are separated by more than 4¥ their length and by the more complex curves of the spiracular openings.

COPESTYLUM SATUR (OSTEN SACKEN, 1877) Larva and puparium (Fig. 20): Dorsal abdominal vestiture confined to medial areas on the transverse bands. Ventral abdominal vestiture of varying length with anterior ends of folds with longer setae than posterior ends. Posterior breathing tube yellowbrown, surface corrugated and shiny, about half width of puparium. TR barely discernable. AP bulging at apex, tapering slightly and 0.75¥ as long as a pupal spiracle. Spiracular openings at apex with simple s-shaped curves. Pupal spiracles long, about 3¥ as long as basal width, slightly outcurved, shiny red with openings in upper third and separated by 1.4¥ their length (Fig. 49). Taxonomic notes: Copestylum satur is more similar to C. fornax (Townsend, 1895) than to C. fraudulentum (Williston, 1891). It is distinguished from C. fraudulentum by the shallow TR and vestiture confined to medial areas of abdominal transverse folds and from C. fornax by the yellow-brown, slightly tapering posterior breathing tube and the longer pupal spiracles which are about 3¥ basal length and which are separated by less than 2¥ their length.

COPESTYLUM SMITHAE (THOMPSON, 1965) Puparium: (prothoracic plate missing), length 4 mm, anterior fold without extra large spicules. Abdominal vestiture of short, upright setae. Anal lobe with indistinct broad setae. Anteriorly directed spicules little sclerotized and indistinct or possibly absent on the ventral surface of the abdomen. Posterior breathing tube orange, not tapering. AP smooth and shiny and about 0.8¥ as long as TR is wide. Pupal spiracles orange, matt, shining apically, and with openings in upper two thirds. Pupal spiracles about 3¥ as wide apart as a pupal spiracle is long. Taxonomic notes: The adult of C. smithae is similar to adults of the Pictum group in general form but has unmarked wings and thick, scale-like setae on the eyes that set this group apart (F. C. Thompson, unpubl. data). The larva is distinct from other species described here by its small size and pupal spiracles separated by about 3¥ their length. The absence of anteriorly directed spicules on the ventral surface of the abdomen indicates that this is not a member of the Pictum group. It was not possible to determine the presence of anterior spiracles, another character indicating membership of the Pictum group, because of the absence of the prothoracic plate from the specimen.

COPESTYLUM QUADRATUM (WILLISTON, 1891) Larva and puparium: Anterior fold with band of spicules narrowing towards the lateral ends. Longest vestiture of dorsum of prothorax longer than longest spicules on the anterior fold. Posterior breathing tube with AP about as long as wide above inconspicuous TR. AP tapering to about two-thirds of width of TR and 1.1¥ as long as TR is wide. Pupal spiracles about the same length as the AP and separated by about 1.3¥ their length with openings surrounding the apex. Taxonomic notes: Copestylum quadratum is most similar to C. milae from which it differs by having the openings of the pupal spiracles surrounding the apex rather than being on the apex and by having the AP slightly longer than the TR is wide. Copestylum quadratum is separated from C. hidalgense by the absence of spicules on the anterodorsal margin of the mesothorax.

COPESTYLUM ORNATUM (WILLISTON, 1891) Puparium: (prothoracic plate missing), largest species of the group, puparium length 9 mm. Anterior fold without extra large spicules. Thorax with lateral fold bearing sensilla 4 of mesothorax wider than band immediately below bearing sensilla 5. Abdominal vestiture of short, upright setae. Anal lobe without spicules. Posterior breathing tube orange, tapering. AP punctured and shiny, and as long as TR is wide. Pupal spiracles dark orange, matt, shining apically, and with openings in upper third. Pupal spiracles 1.1¥ as wide apart as a pupal spiracle is long. Taxonomic notes: Copestylum ornatum is similar to those species of the Pictum group having a tapering posterior breathing tube. It can be separated from these species by its large size (puparium length 9 mm), upper thoracic lateral fold being wider than the fold immediately below and having dark orange pupal spiracles. In having dark orange pupal spiracles it is similar to C. imitans but may be separated from that species by its tapering posterior breathing tube.

COPESTYLUM COCHABAMBA ROTHERAY, MARCOS & HANCOCK SP. NOV. Adult: Male holotype: face with lateral margins inflated and with slight lateral tubercles near the eye margins below the antennae. Face indented slightly from just above margin of mouth so lower part of face appears as a narrow projection (view from in front). Face and genae yellow and yellow haired except for some black hairs on the central tubercle and on the lower lateral margins of the face. Face without vittae. Tubercle large and prominent and elongate oval in side view. Mid point of tubercle appearing below the mid point between the antennae and the mouth Fig. 5). Frons yellow with black hairs. Antennae yellow with plumose arista and basoflagellomere slightly constricted in the middle and 2.5¥ as long as broad, rounded apically. Ocellar triangle dark yellow and black haired, suture about same length as ocellar triangle. Eyes with yellow hairs reaching lower margins, slightly longer on top of head. Ground colour of mesonotum black except for vague yellowish lateral and posterior margins and transverse suture also yellow marked. Postpronotum well developed, forming a rounded yellow lobe as wide as long with long, yellow and black hairs and two to three black bristles on posterolateral margin. In profile view mesonotum has mixed length pale and black hairs but when viewed from behind, mesonotum has an alternating pattern of hairy, gold and black stripes. Lateral margins with mixed long pale hairs and black bristles. Posterior margin with a row of eight+, thin, prescutellar black bristles, these bristles stronger towards the medial line. Scutellum dark yellow with mixed length black hairs except for pale haired margins and posterior margin with six very strong, socketed, black bristles. Pleurae black except for yellow mark on dorsal margin of posterior anepisternum and densely coated in long yellowish hairs and a row of six+ black bristles on the posterior anepisternum. Wing membrane hyaline, without microtrichia. Legs black with yellowish tibiae and completely black haired. All sternites brown, shiny with long pale hairs. Tergites 1–3 dark yellow, tergite 4 black all coated in short and posteriorly reclined black hairs. Hairs on tergite 4 longer than on other abdominal tergites. Genitalia: in profile view, surstylus longer than basally wide, rounded and slightly tapered at the apex with dark bristles on the inner and anterior sides. Cerci flat tipped. In profile view, epandrium longer than basally broad. Hypandrium indented ventrobasally with below, a rounded ridge across the ventral margin. Hypandrium smoothly punctured and covered with fine pile. Superior lobe dorsally rounded and with a hook shaped apex (Figs 10, 11). Female: Similar to holotype male; width of vertex about 2/5 width of head. Length: Body 13.0– 13.1 mm; wing 12.5 mm (N = 2). Puparium: Anterodorsal margin of mesothorax with enlarged setae and spicules. Dorsal vestiture of abdomen spread across folds and not strongly confined to medial transverse bands. Crochets translucent with red tips. Posterior breathing tube dark brown, short, about 1/10 as wide as puparium, AP only 0.6¥ as long as TR is wide, coriaceous not tapering and slightly bulging ventrally with midventral groove ending before halfway point to TR. Pupal spiracles about 1.6¥ as long as AP and 1.2¥ as wide apart as a pupal spiracle is long. Material examined: Holotype: male with puparium BOLIVIA, Cochabamba, ix.2004, ex decaying Opuntia. Known only from this locality, collected by G. E. R. and E. G. H. (NMS). Paratype: 1 ♀ with puparia, same data as holotype (HM). Etymology: The name refers to ‘Cochabamba’, the Bolivian locality where the larva of the type specimen was collected. Taxonomic notes: In the Scutellata group key of Fluke (1951), the adult of C. cochabamba keys out to C. rectum (Wulp, 1882). Fluke (1951) provided a description of a species that he determined as C. rectum but questioned whether his determination was correct on the basis of discrepancies between his specimens and the description of recta given by Wulp. Copestylum cochabamba differs from both C. recta Wulp and C. rectum sensu Fluke (1951) in the following combination of characters: a flattened not a well rounded facial tubercle, black not pale haired facial margins, pale not black hairs on the abdominal sternites, and in the male genitalia by a rectangular not squareshaped epandrium with surstyli that are taller rather than shorter than basally long. The puparium of C. cochabamba is distinguished from other early stages of the Scutellatum group by the dark brown posterior breathing tube which does not taper, AP about half as long as TR is wide and the pupal spiracles which are about as long as TR is wide., Published as part of Rotheray, Graham E., Marcos-García, Maria-Angeles, Hancock, Geoff, Pérez-Bañón, Celeste & Maier, Chris T., 2009, Neotropical Copestylum (Diptera, Syrphidae) breeding in Agavaceae and Cactaceae including seven new species, pp. 697-749 in Zoological Journal of the Linnean Society 156 (4) on pages 713-714, DOI: 10.1111/j.1096-3642.2008.00503.x, http://zenodo.org/record/5443474, {"references":["Fluke CT. 1951.

Etymology: The name tetetzoi refers to the cactus species Neobuxbaumia tetetzo from which the holotype was reared. Taxonomic notes: The adult of this species can be easily separated from other Marginatum group adults by the male genitalia, black frons, and wings hyaline without brown spots. The larva and puparium of C. tetetzoi is similar to C. bequaerti and C. lentum in having an AP which is shorter than the width of the TR. The nontapering punctured AP separate C. tetetzoi from C. lentum and the absence of anterior spiracles separates it from C. bequaerti., Published as part of Rotheray, Graham E., Marcos-García, Maria-Angeles, Hancock, Geoff, Pérez-Bañón, Celeste & Maier, Chris T., 2009, Neotropical Copestylum (Diptera, Syrphidae) breeding in Agavaceae and Cactaceae including seven new species, pp. 697-749 in Zoological Journal of the Linnean Society 156 (4) on pages 709-710, DOI: 10.1111/j.1096-3642.2008.00503.x, http://zenodo.org/record/5443474

The absence of anterior spiracles, mixed long and short abdominal vestiture, smooth not punctured AP, and spicules on the anterodorsal margin of the metathorax separate this species from others in this species group.

COPESTYLUM CURRANI (FLUKE, 1951) Puparium: Anterodorsal margin of mesothorax with enlarged setae, not spicules. Dorsal vestiture of abdomen spread across folds and not strongly confined to medial transverse bands. Crochets translucent with red tips. Posterior breathing tube dark brown, about 1/10 as wide as puparium, AP about 0.67¥ as long as TR is wide, lightly punctate and slightly tapering. Pupal spiracles about as long as AP and about 1.8¥ as wide apart as a pupal spiracle is long. Taxonomic notes: The puparium of C. currani is distinguished from other Scutellatum group species by the slightly tapering posterior breathing tube which is dark brown and with the AP just over half as long as TR is wide.
