Blepharoneura zapoteca Hernández-López & Hernández-Ortiz , new species

( Figures 5 A–D )

Diagnosis. This species shares morphological similarities with B. amplihyalina Norrbom & Condon , B. marshalli Norrbom & Condon , and B. regina Giglio-Tos by having wings with broad hyaline areas, mainly in the medial section of cells r 1, r 2+3, r 4+5, dm and cu 2; in addition to a subapical hyaline spot on the pterostigma [#3], while the distal margin of cell dm is mostly brown, except in some individuals of B. regina (see Fig. 58 in Norrbom & Condon 2010). This new species differs from all the above species by having the pleuron and scutellum disc largely dark brown, and by the apicoventral spot on the hind femur not exceeding ¼ of its length. In addition, it can be distinguished from B. amplihyalina and B. marshalli by the presence of two well-delimited rectangular hyaline blotches in cell br [#13, #44] near crossvein R-M, and by two hyaline dots in cell bm [#19, #20]. It matches B. regina in the bm-cu/dm-cu ratio (<0.60) but differs by the presence of only one subapical hyaline dot in cell r 1 [#6].

Description. Head ( Figs. 5A,C ): Face yellow; frons with two brown striae from anterior lunule to ocellar tubercle; 2 frontal setae; 2 orbital setae; ocellar seta long, well developed, twice as long as posterior orbital seta; scape yellow, pedicel and flagellomere with some brown coloration; arista pubescent, yellow basally, dark apically; genal area widely brown, and genal seta black; labella with rows of spinules; ocellar tubercle blackish, this coloration not extending beyond postocellar setae; posterior ocular margins darkened; lateral areas of vertex yellow; middle occipital sclerite with two submedial brown stripes; lateral sclerites to occipital suture yellow with fuzzy brown stripes, and brown spots not extending beyond postocular seta.

Thorax ( Figs. 5A–C ): Mesonotum 2.51 mm long, 1.59 mm wide; (M-ratio= 1.59x); the following setae are present: 4–5 scapulars; 1 postpronotal, 1 presutural supra-alar, 1 postsutural supra-alar, 1 postalar, 1 intra-alar, 2 intra-postalars, 1 dorsocentral slightly above postalar level; 1 acrostichal; and 3 scutellars. Scutum dark brown setulose dorsally, mostly microtrichose; postpronotal lobes yellow, weakly dark on anterior margin; overall pattern of scutum with distinct submedial and sublateral brown stripes; submedials weakly connected, and sublaterals shortly separated at transverse suture; postsutural sublateral stripes long, and submedials reaching level of dorsocentral seta; anterior spot to postsutural supra-alar seta present; spot below postalar seta present; scutal posterior margin with two large brown spots separated medially; scutellum microtrichose largely brown on disc, extending from scuto-scutellar suture close to apical setae; lateral bases of scutellum yellow; subscutellum and mediotergite mostly brown, interrupted by a narrow yellow medial stripe; notopleuron mostly brown along posterior margin; anepisternum with anterior brown marking, yellow behind of phragma; the katepisternum, katatergite, anepimeron, anatergite and meron mostly brown; basalare brown; fore- and mid-legs pale yellow; hind-legs yellow, with an apicoventral brown blotch on femur covering less than ¼ length.

Wing ( Fig. 5D ): Length 6.66 mm, 2.81 mm width (W-ratio= 2.37x); crossvein R-M at 0.59x distance between BM-Cu and DM-Cu; tip of vein R 1 ending beyond R-M level; dorsal setulae on vein R 4+5 extending beyond R-M; vein Cu 1 setulose dorsally along body of cell bm and extending close to DM-Cu; wing pattern basal third largely hyaline along the basal cells r 1, br, bm, bcu, alula and anal lobe; apical third of wing pattern largely spotted, with extensive hyaline spots on apices of cells r 1, r 2+3, r 4+5 and m; costal cell with two square hyaline spots separated by a well-defined brown stripe; basal hyaline mark on cell br present [#12], apical half with two hyaline spots [#44, #13] present; cell bm with two hyaline spots [#19,#20]; body of cell bcu largely hyaline, posteroapical corner brown; alula and anal lobe hyaline; pterostigma with subapical hyaline spot present [#3]. Basal section of cell r 1 mostly brown, basally with two small weak pale dots, medially with a trapezoidal hyaline mark [#5], connected inferiorly with hyaline spots on cells r 2+3 [#8, #9], and r 4+5 [#14, #15], subapical hyaline spot present [#6] reaching costal margin; cell r 2+3 with single basal hyaline spot, and two wide hyaline marks merged medially [#10, #11]; cell r 4+5 with large subbasal hyaline spot [#14] reaching inferior margin, apparently fused with hyaline spot [#15] above DM-Cu, and three preapical spots, one of them open to costal margin; cell dm with large hyaline patch, covering most of the length of body cell, probably fused with anterior [#25] and posterior [#53] hyaline spots, apical margin brown; cell m with three large rounded hyaline marks, isolated from others of cell r 4+5, two of them open to wing margin; proximal spot [#49] close to DM-Cu present; cell cu 2 mostly hyaline reaching posterior margin, probably as a result of the fusion of several hyaline marks [#31, #32, #33], and subapical hyaline spot [#37] present.

Abdomen ( Fig. 5B ): Tergites brown stripped, fused laterally on edges of tergites 3–5; syntergite 1+2 with two large subcentral brown markings extended on sides; sternite 5th mostly brown.

Male terminalia: Not dissected.

Female: Unknown.

Material Examined. Holotype ♂ ( IEXA) MEXICO. Oaxaca, Concepción Pápalo , 2500m, 17.8417°N 96.8806°W, 11 Jul 1997, G Nogueira.

Etymology. The epithet of this species derives from the name of indigenous inhabitants belonging to the Zapoteca culture from the state of Oaxaca, Mexico.
