Pachyanthidium (Trichanthidium) anoplos sp. n.

(Figs 13–14)

Diagnosis. The presence of a ventral carina on the mid femur will distinguish P. anoplos from all Pachyanthidium not in the subgenus Trichanthidium, as will the combination of hairy eyes, absence of arolia and lateral spines on T2–T5. Males can be distinguished by T6 not having lateral lobes, but is rather gently curved, T6 with tiny dorsolateral lobes, a small posteromedian and ventrolateral spines. Males differ in T7 with lateral projection stout and median spine short, not strongly acute.

Description. FEMALE. Lengths: head 2.8–3.3 mm; scutum 1.6–2.1 mm; forewing 6.8–7.8 mm; body 6.7 mm. Colour black with variable yellow to reddish-orange markings: clypeus with ventrolateral spots (Fig. 14 a) to extensively marked, mandible with maculations in middle to extensive, markings present or absent on posterior margin of vertex, gena, pronotum, lateral and ventral mesosoma, lateral axilla, lateral and posterolateral scutellum, legs, T2–T5 with dorsolateral markings that range from spots (Fig. 14 b) to comma-shaped; markings present or absent on T6 and all sterna. Structure. Preoccipital lamella distinct (longer than median ocellus diameter); eye hairy; clypeus ventral edge straight, weakly crenulate; mandible spatulate, 2 broad outer teeth, 2 very small inner teeth; lateral margin of scutum slightly lamellate; pronotal lobe strongly lamellate; omaulus strongly lamellate; forebasitarsus short and narrow, length 0.6x foretibia, width 0.3x lengths; arolia absent; T2–T5 with lateral spines, T6 gently curved laterally (Fig. 14 c).

MALE. Lengths: head 2.5 mm; scutum 1.5 mm; forewing 6.8 mm; body 5.7 mm. Male mostly reddish with yellow clypeus, mandible, inner lower paraocular area, fleck adjacent to clypeus (Fig. 14 d), comma-shaped marks on T2–T3 (Fig. 14 e), posterior T6 and entire T7. Structure (Fig. 14). Preoccipital ridge distinctly lamellate; eye hairy; supraclypeus slightly raised; subantennal suture bowed gently outwards (inconspicuous); antennal flagellum length 1.3x eye length, 4.5x scape length; clypeus with ventral edge straight, smooth; mandible 3–toothed; lateral margin of scutum slightly lamellate; forebasitarsus sparsely pubescent, not distinctly fringed; forebasitarsus length 0.6x foretibia length, 2.5x its width, anterodistal extension not visible; hind basitarsus narrow, width one-third length; arolia absent; T1 unmodified laterally; T2–T6 each with small posterolateral spine; T6 with minute point posteromedially, small spike ventrolaterally, tiny lobe dorsolaterally (Fig. 14 f); T7 with broad, rounded lateral projection, pointed median spine (Fig. 14 g); terminalia as in P. benguelense (cf. Fig.8 d-g).

Distribution. Pachyanthidium anoplos is known only from the Central African Republic and Cameroon (Fig. 13).

Etymology. This species is named for the absence of a dorsolateral spine on the male T6.
