Ordo: Hymenoptera
Familia: Braconidae
Genus: Heerz
Name
Heerz ecmahla Martínez, Zaldívar-Riverón, Ceccarelli & Shaw sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnosis
Heerz ecmahla distinguishes from the remaining species of the genus by the uniformly coriaceous sculpture on the first and second metasomal tergites (Fig. 2C). It also distinguishes from the Central and South American species, Heerz tooya and Heerz lukenatcha, by its entirely hyaline wings (Fig. 2A) [wings partially or totally infuscate in the latter two species (Fig. 2B)], and from Heerz macrophtalma by its relatively smaller eyes (Fig. 2D) [considerably large in Heerz macrophtalma (Fig. 3B)] and distinctly longer ovipositor (Fig. 2A) [about 0.5 times as long as metasoma in Heerz macrophtalma (Fig. 3A)].
Description
Female. Colour: Body honey yellow, antennae honey yellow, turning darker apically; legs yellow, median lobe of mesoscutum and upper half of mesopleuron light brown; metasoma slightly lighter; wings hyaline, veins, pterostigma and tegula light brown. Body length: 2.5 mm. Head: vertex, frons and temple striate, gena smooth, face acinose; eyes large, its height 1.3 times its maximum width (lateral view); malar space about 0.3 times eye height (lateral view); ocello-ocular distance two times the diameter of lateral ocellus and 1.5 times longer than posterior ocellar line; antennae with 21 flagellomeres. Mesosoma: length of mesosoma 1.9 times its maximum height; pronotum essentially smooth, pronotal groove largely smooth, with a few rugae medially; mesoscutal lobes coriaceous; notauli scrobiculate, obscured in a posterior rugose median area; scutellum smooth, scutellar sulcus deep and scrobiculate, with four longitudinal carinae; mesopleuron largely smooth, posterior mesopleural sulcus distinct and scrobiculate; subalar groove scrobiculate; precoxal sulcus smooth; metapleuron rugulose; dorsolateral areas of propodeum coriaceous; propodeal areola distinctly delimited by carinae and essentially coriaceous. Legs: fore tibia with a row of 12 spines; hind coxa mostly smooth, with a distinct basoventral tooth. Wings: fore wing 2.9 times longer than wide; length of pterostigma 2.7 times its maximum width, 0.6 times length of vein R; vein r 1.5 times longer than vein 3RSa; vein 3RSa 0.8 times length of r-m; vein m-cu distinctly antefurcal; (RS+M)b present, 0.3 times length of vein 2RS; hind wing with vein M+CU 0.8 times as long as 1M and 1.5 times length of vein r-m; vein m-cu slightly curved towards wing apex. Metasoma: first metasomal tergite short, 1.1 times as long as its apical width, entirely coriaceous, with two dorsolateral carinae running through anterior half of median tergite, without a median dorsal area fully delimited by carinae; second metasomal tergite coriaceous, with two slightly convergent furrows basally; third metasomal tergite smooth, turning coriaceous laterally and with a transverse scrobiculate furrow; remaining metasomal tergites smooth and polished; ovipositor 1.1 times length of metasoma, with a single, reduced node.
Male. Essentially as female, body length 2.7 mm.
Variation. Females: Body length 2.5–2.7 mm; eyes 1.1–1.2 times higher than wide (lateral view); fore wing length 2.5–2.6 times its maximum width; length of pterostigma 2.6–2.7 times its maximum width; hind wing vein M+CU 0.8–1.0 times as long as vein 1M.
