Aleiodes shakirae is a hymenoptera fromthe brackish wasp family (Braconidae). The species is named after the singer Shakira , because caterpillars parasitized by this brackish wasp curve and turn their abdomen in various ways and this reminded the eponymous scientists of the belly dance of Shakira.
features
female
The female holotype has a length of 6.0 millimeters, a forewing length of 5.7 millimeters and antennae 7.4 millimeters long . The body length of the paratypes varies between 4.5 and 6.2 millimeters. The head is yellow, the triangle within the point eyes ( ocelli ) is dark brown. The antennae are dark brown-black, the scapus is somewhat lighter dorsally . The mesosoma is yellow, the anterior corner of the mesopleuron , the metanotum and parts of the lunulae, the propodeum and metapleuron are dark brown-black. Near the border to the metapleuron, the mesopleuron is light yellowish-white, but blackish directly at the border. The hips ( coxae ) of the front and middle legs are whitish, the thigh ring (trochanter) and trochantellus darken towards the tip from light yellow to honey brown. The hips of the hind legs are white on the basal half, otherwise black, the thigh ring and trochantellus are black, ventrally with a white stripe. The thighs ( femora ) and splints ( tibiae ) are whitish and have darkened areas laterally-central and at the tip. The Spurs of the rails and the Telotarsen are honey-brown, the other tarsi are brown. The terga on the metasoma are black, but the fourth to seventh tergum is white on the sides. The ventral side of the metasoma is also white. The sheaths of the ovipositor are apical dark brown, basal whitish. The wings are transparent, but have a brown wing mark with a slightly lighter center.
The antennae of the holotype have 47 segments, the antenna segments (flagellomeres) are approximately twice as long as they are wide and the last antenna segment has a long tip in the shape of a baby bottle teat. The paratypes have antennae with 47 to 50 segments. The head shield ( clypeus ) is not swollen. The moderately large point eyes are close to the compound eyes: their distance is about 0.45% of the diameter of the lateral ocelli. The head has a finely granulated surface, the occiput is smooth and shiny. There are some folds on the upper part of the face just below the toruli. The mesosoma is finely granulated, the propodeum has a complete longitudinal groove in the middle. The groove on the rear edge of the mesoscutum is also complete. The forewing stigma is 4.5 times longer than it is high. No m-cu cross vein is formed in the hind wings . On the metasoma the first three terga are granulated and wrinkled, the others granulated. A complete groove runs in the middle from the first to the entire third tergum. The sheaths of the ovipositors are about the same length as the second segment of the tarsi of the hind legs.
The animals essentially only show color variation in the legs. The legs of the paratypes are slightly darker compared to those of the holotype and / or the trochantellus of the middle legs is laterally darkened.
male
The antennae of the males have 44 or 46 segments. Your point eyes are larger and the distance between the point eyes and the compound eyes is about a third of the diameter of the lateral point eyes. Their first tergite is narrower and about twice as long as it is apically wide.
Doll
The pupa is 14.0 to 18.7 millimeters long and is dark in the middle, reddish brown and light brown in the front and back. The thorax is narrow and wrinkled. The pupa is widened behind the imago's escape hole. Otherwise, their general shape is long and slender; Curved down or to the side in a V-shape to almost straight. The exit hole is dorsally behind, in front of the abdomen . In one specimen, however, it was ventral.
Occurrence
The type locality of the species is the research station "Yanayacu" in the province of Napo , Ecuador . There the type specimens - the holotype and five female and six male paratypes - were caught in a malaise trap on bamboo in the cloud forest at 2163 meters above sea level between June 10 and 16, 2010. In the years 2006 to 2011 and 2013, further specimens were caught there with malaise traps in different months, and three females and six males were reared from caterpillars.
Way of life
The previously known specimens of Aleiodes shakirae developed from a caterpillar that lived on Chusquea scandens (family of sweet grasses (Poaceae)). The unknown butterfly species is called "palito café chusquea" and is also parasitized by Aleiodes nubicola and Aleiodes mirandae . Presumably, all parasitized caterpillar specimens found that were in the second and third instar were the same species of spider. The previously known specimens of Aleiodes shakirae required 2.5 to 6 weeks from pupation to hatching of the adults . While the doll is resting, the dolls dry so differently that the middle part curves differently than the rest, resulting in a characteristic curve of the doll.
Taxonomy, systematics and diagnostic features
Aleiodes shakirae belongs to the circumscriptus / gastritor group. The V-shaped pupae on caterpillars and some color features suggest a similarity with Aleiodes townsendi , but Aleiodes shakirae differs from this species by the distance between the point and compound eyes. This is about half the diameter of the lateral ocellus, in Aleiodes townsendi it is about the same. Also in Aleiodes shakirae the metapleuron and the metasoma on the back are black, whereas in Aleiodes townsendi the former and the first tergum are predominantly white with black patterns; the hips of the hind legs are basal white and apical black and not the other way around; the rails and tarsi of the hind legs are darker; the spurs of the rear rails are yellowish to honey-yellow and not black; the structure of the first three terga of the metasoma are granulated-wrinkled and not granulated-grooved; the metasoma is much slimmer; the stalk is 1.7 to 2.0 times longer than it is wide at the tip (1.2 times in Aleiodes townsendi ) and in the hind wings there is no m-Cu cross-vein at all .
