Blepharoneura femoralis: Condon & Norrbom 1999: 161 View in CoL [misidentification].

Diagnosis. This species belongs to the femoralis complex (see diagnosis of B. femoralis ), species of which are difficult to distinguish except by aculeus shape. That of B. cyclantherae differs from those of B. osmundsonae and nigrifemur in having the tip stouter (lobed part half as long as wide) and not rounded proximal to the lateral lobe. The lobes, particularly the lateral one, are more acute than in other species except B. osmundsonae and the gaps are shallower than in B. femoralis which also has a convex medial lobe. The sublateral lobe also is similar in size to the submedial lobe, unlike in B. zumbadoi and femoralis . Blepharoneura cyclantherae also differs from B. osmundsonae in having acute rather than polygonal scales on the medial membrane, and they are present only dorsally and are less extensive than in other species of the complex.

Description. Head: Dark brown area on ocellar tubercle extended more than half distance to postocellar seta (except in teneral ♂). Medial vertical seta in yellow area. Medial occipital sclerite with pair of brown submedial vittae on ventral half. Occipital suture narrowly dark brown, on lateral side bordered by slightly paler band, extended dorsolaterally to postocular setae but well separated dorsally from lateral vertical seta.

Thorax: Scutum with large irregular medial nonmicrotrichose area, extending posteriorly to transverse suture and on submedial vittae to midway between suture and dorsocentral seta, extending laterally to lateral margin of submedial vitta and on posterior half of presutural part to lateral margin of sublateral vitta, also with at least a small nonmicrotrichose area on anterior half of postsutural sublateral vitta; scutum also with 2 pairs of dark brown vittae or rows of spots; submedial vitta interrupted or narrowed slightly posterior to transverse suture and not connected to mark or marks on posterior margin; sublateral vitta broadly interrupted at transverse suture and separated from mark on posterior margin; posterior margin with 2 brown marks or with 1 broad mark narrowed medially. Notopleuron with dark brown vitta on lateral margin. Small brown spot anterior to postsutural supra-alar seta present or absent. Brown vitta anterior to postalar seta and brown spot lateral to dorsolateral corner of scutellum present. Scutellum with pair of submedial brown marks or single inverted U-shaped medial mark usually extended to basal margin. Subscutellum and mediotergite with pair of dark brown vittae and ventral half of lateral margin of mediotergite also narrowly brown or both sclerites brown except narrow medial vitta and dorsolateral corner of mediotergite yellow. Pleuron mostly dark brown, yellow only on propleuron, most of anepisternum (with large dorsomedial dark brown spot extending ventrally 1/3–2/3 distance to ventral margin, and narrowly brown in posteroventral corner), extreme anterior and posterior corners of katepisternum, all of katepimeron, greater ampulla, narrow dorsal, posterior and ventral margins of anepimeron, and narrow posterodorsal margin of katatergite and anterodorsal margin of anatergite. Basalare brown. Dorsocentral seta aligned slightly anterior to postalar seta.

Legs: Mostly yellow. Mid femur sometimes with anteroventral and posteroventral brown marks on apical 1/5–1/4. Hind femur with entire apical 1/4–1/3 dark brown.

Wing ( Fig. 26 View FIGURES 26–35 ): Length 5.50–6.00 mm, width 2.70–2.88 mm, ratio 2.04–2.08. Crossvein r-m at 0.56–0.57 distance from bm-cu to dm-cu. Cell c with 2 broad rectangular hyaline spots, both reaching costa and subcosta; medial brown area almost as dark as to distinctly paler than area of cell r1 posterior to pterostigma, sometimes paler medially, distinctly narrower than both hyaline spots. Pterostigma usually with large subapical hyaline spot [#3] (absent in 1 of 3 specimens) but usually not reaching R1 (on 1 wing of 1 specimen). Cell r1 basally (proximal to apex of R1) with pale brown spot posterior to apex of vein Sc; cell r2+3 occasionally (1 wing of 2 specimens) with 1 pale brown spot. Radial cells medially with 1 broad quadrate basal hyaline mark [#5 fused with additional spot?] in cell r1, sometimes with very small pale brown spot partially dividing it posteriorly; cell r2+3 with 2 hyaline spots [#8, #9] or usually 1 broad hyaline spot aligned with r1 mark, extending across cell; cell r4+ 5 in anterior half sometimes with small hyaline spot [#14] aligned with middle of r1 mark, less than half as wide as cell, sometimes minute or absent, and with medial hyaline spot [#15] near anterior end of dm-cu small. Distally cell r1 with or without 1 marginal subapical hyaline spot [#6]. Cell r2+3 with 2 large marginal hyaline marks [#10, #11], proximal mark sometimes constricted medially or divided into marginal and posterior spots. Cell r4+5 with small hyaline spot [#16] anteriorly, aligned with more proximal or between apical marks in cell r2+3; with 1 ovoid hyaline spot in posterior half of cell aligned with distal mark in cell m, in 1 specimen fused with posterior marginal spot; and with 2 ovoid marginal or submarginal hyaline spots [#18, #18A]. Cell m without subbasal hyaline spot [#49] near midlength of dm-cu; with 2 marginal hyaline spots [#27, #29] and 1 large anteromedial spot [fused #26, #26A], narrowly separated from proximal marginal spot and vein M. Cell br with subbasal hyaline spot [#12]. Cell bm without subbasal hyaline spot [#19], with large circular subapical hyaline spot [#20]. Cell bcu with or without hyaline spot in lobe. Posteromedial part of wing with large broad hyaline areas; cell br with subapical hyaline spot [#13]; cell dm with broad and long hyaline area [fusion of at least #52, #21, #22, #23, #24, sometimes #50], sometimes narrowly or partially divided by pale brown medially, narrowly separated from or reaching vein M proximally, sometimes extended to level of r-m anteriorly, tapered distally, extending farther posteriorly than anteriorly; cell cu1 with large medial anteriorly trilobed and posteriorly 1–2 lobed mark or with more broadly fused area with 0–2 anterior and 1–2 marginal brown spots [fused #31, #32, #33, #36, sometimes #36A], broad on posterior wing margin, proximal marginal part [#34, #39] across apex of vein A1+Cu2 sometimes narrowly isolated; subapical marginal hyaline spot [#37] reaching vein Cu1. Cell dm with anteromedial subapical hyaline spot [#25] sometimes connected to proximal hyaline area.

Abdomen: Syntergite 1+2 with pair of submedial brown spots narrowly connected to posterolateral brown bands to form pair of irregular marks. Tergites 3–5 with typical 2 pairs of spots and L-shaped posterolateral bands fused to form pair of irregular somewhat W-shaped lateral dark brown marks, separated medially, or with submedial spots sometimes isolated, sublateral spots also isolated on tergite 5 of 1 female; usually also with isolated anterolateral spot.

Female terminalia: Oviscape entirely dark brown, length 0.97 mm. Aculeus ( Fig. 137 View FIGURES 136–145 ) 0.55 mm long, 1.94–2.00 times as long as wide, with acute scales proximally on medial membrane dorsally, but without scales ventrally; tip angulate basolaterally, slightly elongate triangular (lobed part 0.48–0.49 times as long as wide), with small, notched medial lobe, and 3 pairs of step-like lobes with small acute apices separated by relatively shallow gaps; sublateral and submedial lobes similar in size; lateral gap 0.89–1.00 times as long as wide. Spermathecae subspherical, with straight slender sclerotized neck and large cylindrical basal apodeme (similar to B. femoralis ).

Male terminalia: Medial surstylus with medial prensiseta on long lobe, lateral prensiseta absent.

Distribution. Mexico (Morelos). The type locality is at approximately 2170 m elevation.

Etymology. The name of this species is derived from that of its only known host plant.

Biology. We reared the three type specimens of this species from fruits of Cyclanthera dissecta Arn. in central Mexico ( Figs. 204–205 View FIGURES 204–209 ). The larvae fed extensively on the developing seeds and other tissues within the fruits. They pupated and then apparently entered a diapause as the adults did not emerge (under laboratory conditions) until 8–11 months after collection of the larvae.
