Material examined

HOLOTYPE: Female, Colombia, Amazonas: Parque Nacional Natural Amacayacu Caño Mata Matá, 3°41'N, 70°15'W, Malaise trap, Martin Kelsey: 200 m, II-III.1989 (ICN 083474). PARATYPES: 1 female, same data as holotype (ICN 083472); 1 female, same locality, 300 m, 1.III.1988, bosque de tierra firme (ICN 083471).
Non-type material: 1 male, same locality, bosque de várzea (ICN 083473).

Diagnosis

This species can be diagnosed from all other Neotropical Apechoneura by the combination of the following: head orange; mesosoma and legs mostly orange (hind leg partly black); metasoma black. Epicnemial carina absent. Metapleuron with a conspicuous sharp lateral denticle. Hind wing with first abscissa of Cu1 0.2× as long as cu-a.

Description

Female. Fore wing length 15.0 mm.
Head. Clypeus almost flat, with a weak transverse ridge near apex; malar space 0.6× as long as basal mandibular width; lower face at narrowest point 0.9× as wide as height from clypeofacial suture to level of insertion of antenna; hypostomal carina joined to occipital carina far from base of mandible; posterior ocellus separated from eye by 1.3–1.5× its own maximum diameter. Antenna with flagellomeres 1 and 2 subequal by length; subapical flagellomere slightly elongate.
Mesosoma. Pronotum with upper hind margin swollen, forming a small conical projection; scutoscutellar groove broad and shallow; scutellum with three evident rugae posteriorly; epicnemial carina absent (Figs 1, 3, 5); sternal region of mesothorax smooth and polished; metapleuron with a rather conspicuous sharp lateral projection near posterior end; submetapleural carina narrow with a distinct low median denticle (Fig. 1). Propodeum in profile more or less flat; anterior transverse carina complete laterally, separating area spiracularis from area lateralis, mediodorsally incomplete so area basalis is not enclosed posteriorly; area basalis slightly transverse; lateromedian longitudinal carina not present behind anterior transverse carina (Figs 7, 9).
Legs. Fore leg with tibia slightly inflated, tarsus with long hairs on inner surface; mid leg with tibia bearing several stout spines.
Wings. (Fig. 12) Fore wing with areolet large, anteriorly narrowly truncate, with 2m-cu joining it very slightly basal of middle; second discal cell short, with vein 1m-cu about half as long as abscissa of Cu1 between Rs&M and 1m-cu; hind wing with apical abscissa of Cu1 joining cu-a clearly closer to M than to 1A; first abscissa of Cu1 0.2× as long as cu-a.
Metasoma. Tergite 1 slender, 3.5–4.0× as long as posteriorly broad; sternite 1 short, reaching about 0.3–0.4 of length of tergite, with a median swelling centrally. Tergite 2 1.9–2.3× as long as posteriorly broad, with isolated pubescence; tergite 7 mediodorsally without an indentation posteriorly; tergite 8, in lateral view, tapered to a bluntly rounded apex, without a cornus, and with uniformly scattered pubescence; tergite 9 bearing long pubescence. Ovipositor, at rest extending beyond apex of metasoma by 3.5–3.8× the length of the metatibia.
Color. (Figs 3, 5, 7, 10) Head orange; flagellum predominantly black, two basal flagellomeres ventrally reddish. Mesosoma orange. Fore and mid legs orange; hind leg with coxa orange with a ventro-lateral black spot on the apex of the outer side, trochanter and trochantellus black except for some small orange spots, femur, tibia and tarsus black. Metasoma black, hypopygium centrally orange. Ovipositor sheath black except for subapical whitish wide band. Fore wing hyaline, with a distinctive apical black band; pterostigma black.
Variation. The female identified with the code ICN 083471 has the fore wing with the areolet petiolate.
Putative Male. Similar to female in structure, but smaller (fore wing length 10.0 mm). Hind wing with apical abscissa of Cu1 arising from M apical to junction of M + Cu1 with cu-a (Figs 11, 13). Antenna black with apical flagellomeres pale (Fig. 4). Metasoma mostly black, tergites 1–6 with a yellow triangular spot at posterior margin (Figs 4, 8). Metapleuron with denticle smaller and paler than in the female.

Specimen condition

The male exemplar was deteriorated during the drawing process. Its antenna was broken and lost.

Etymology

The species name refers to its color (i.e. metasoma and most part of hind leg black).

Remarks

Apechoneura seminigra sp. n., just like Apechoneura nigricornis, lacks an epicnemial carina; this characteristic separates them from the rest of the species of the genus. As Apechoneura nigricornis, Apechoneura seminigra sp. n. possesses a conical projection on the metapleuron and lacks an indentation on tergite 7. However, the metasoma is orange in Apechoneura nigricornis and black in Apechoneura seminigra sp. n. Also, in the hind wing, the first abscissa of Cu1 is 0.4× as long as cu-a in Apechoneura nigricornis and 0.2 in Apechoneura seminigra sp. n. Although these two species are rather similar morphologically, the difference in color pattern makes in this case their separation reliable. Gauld (2000)[1] examined extensive material of Apechoneura nigricornis from Costa Rica but also some material from Brazil and Peru, and Herrera (2006)[2] examined one specimen of Apechoneura nigricornis collected in Porce (Antioquia, Colombia) in 1998 and no color variation compared to the holotype of this species was found.

Comments

Apechoneura seminigra sp. n. is so far only known from Colombia, Amazonian Region, northwest of Leticia. According to Gauld (2000)[1] there is significant sexual dimorphism in Apechoneura and the sex association is often difficult, in part because the male specimens are less frequently collected. Despite the differences between the female specimens and the male specimen of Apechoneura seminigra sp. n., especially in the hind wing venation, they are tentatively considered here as belonging to the same species, mainly because all the specimens were collected in the same exact locality, in two consecutive years.
