Aleiodes barnardae Quicke & Shaw , sp. n.

( Figures 7–9 )

Material examined

Holotype: Female, Uganda, Kibale Forest National Park, Kanyawara , August 2002, reared from suspended mummy of an ennomine geometrid ( NMS).

Paratypes: Three females, same locality as holotype, one collected and reared August

2002, two in August 2003.

Description Females. Length of body 4.2–4.8 mm; length of fore wing 4.0– 4.2mm; length of tergite 2+3

1.1mm.

Antenna with 40–42 segments (41 in holotype), 1.35 times longer than fore wing. Terminal flagellomere strongly acuminate, 3.4 times longer than wide. Median flagellomeres 2.25 times longer than wide. Sculptured parts of 1st and 2nd flagellomeres equally long. Third segment of maxillary palp 1.3 and 1.6 times longer than the 4th and 5th segments, respectively. Inter-tentorial distance 1.46 times tentorio-ocular distance. Width of clypeus:width of face51.0:2.3. Width of head:width of face:height of eye53.1:1.0:1.8. Face with small elongate median bulge, lateral to this with distinctly transverse rugose striae. Frons depressed and with distinct carina bordering anterior two-thirds of depression laterally, close to but separate from margin of eye. Stemmaticum coarsely rugose. Occipital carina broadly effaced medially.

Mesosoma 1.63 times longer than deep, coriaceous; mid-posterior part of mesoscutum more coarsely sculptured.

Fore wing: Lengths of veins r:3-SR:SR151.0:2.5:5.6. Lengths of veins 2-SR:3-SR:rm51.42:2.6:1.0. Vein 2-CU1 1.4 times longer than vein 1-CU1. Hind wing: Vein M+CU 1.4 times 1-M. Base of wing evenly setose.

Length of fore femur (excluding trochantellus):tibia51.0:1.15. Length of hind femur (excluding trochantellus):tibia:basitarsus52.0:2.7:1.0. Apex of hind tibia without a comb (setal fringe). Claws simple.

Metasomal tergites 2 and 3 with complete mid-longitudinal carina. Second tergite 1.38 times wider posteriorly than medially long. Third tergite 1.7 times wider posteriorly than medially long. Second suture rather weak, slightly anteriorly pointed medially. Posterior margin of 5th metasomal tergite with well-defined posterolateral emargination.. Ovipositor sheath 0.75 times length of hind basitarsus.

Yellow except the following: palps, malar region of face below anterior tentorial pits, fore and mid coxa and trochantellus, posterior half of 1st metasomal tergite, all of metasomal tergites 2–4 white; pronotum, metapleuron, middle of propodeum and hind trochanter whitish; tip of mandible, flagellum, scapus and pedicellus laterally and medially black; wing venation except basal 0.03 of fore wing vein C+SC+R, fore and mid tarsus, apical 0.05 hind tibia and hind tarsus (except paler telotarsus) dark greyish. Ovipositor sheath black with basal 0.2 whitish.

Molecular features

The ITS2 sequence of A. barnardae n. sp. is virtually identical to that of A. kasenenei n. sp ( Figure 5 ), but these two species differ in their CO1 sequences at many 3rd codon positions (see Figure 4 ).

Etymology

Named after Sue Barnard for her friendship and help during the 2002 Kibale field trip.

Figures

Figure 4. Selected contiguous fragment of the CO1 gene in individuals of the Aleiodes buzurae-group from Uganda and Kenya with bold characters indicating substitutions. Asterisks show phylogenetically informative substitutions at species level; exclamation marks show apomorphies for individual species in the buzarae group and $ sites that have both unique and informative variation.

Figure 5. Two fragments of the ITS2 region aligned by eye showing marked differences between species in the Aleiodes buzurae-group. Asterisks and bold font indicate substitutions in length-conserved regions and lines show regions of length variation. Xs indicate uncertainty about number and identity of bases.
