Anthidiellum (Chloranthidiellum) pamae View in CoL sp. n.

( Figs 5–7 View FIGURE 5 View FIGURE 7 )

The black circumference of the female T6 is unique to this species. It is named for my wife Pamela.

Diagnosis. The paraocular areas are mostly yellow, reaching to near upper extremes of eyes ( Fig. 4a, c View FIGURE 4 ), and the genae are mostly yellow. In A. eritrinum , the yellow reaches to little above the antennal sockets and the genae are mostly black. The scutum is mostly black, yellow laterally, and the scutellum is mostly yellow, black anteromesally ( Fig. 5b, d View FIGURE 5 ). The metasoma is usually yellow and black. The female T6 has a yellow disc circumscribed by black, as in A. polyochrum and A. absonulum , which are in a different subgenus. The integument between scutal punctures is striate in narrow inter-puncture areas and reticulate in wider area; sometimes shiny between punctures in A. eritrinum .

Description. Female. Integument of head, mesosoma and metasoma black with golden-yellow maculation on lower face, nearly entire paraocular area (narrowing towards upper inner eye margin), posterior vertex, upper gena, pronotal lobe, anterolateral scutum, axilla, lateral and posterolateral scutellum, most of femora, outer tibiae and tarsi, lateral T1, anterolateral and lateral T2, anterior and lateral T3–T5 (on T3, narrowly interrupted medially), central T6 (circumscribed with black); mandible yellowish ( Fig. 5a–b View FIGURE 5 ). Scopa very pale yellow. Lengths: face 2.4 mm; scutum 1.7 mm; forewing 5.3 mm; body 5.3 mm. Structure. Head. Epistomal suture gently incurved at epistomal pit; lower epistomal suture projection adjacent to inner antennal socket edge ( Fig. 1a View FIGURE 1 ); entire preoccipital carina well developed; scutum gently convex, uniformly punctate ( Fig. 5b View FIGURE 5 ); omaulus broadly lamellate; fore and middle femora with spinose vestiture posteriorly; hind basitarsus narrow (length 2.9x width) (cf Fig. 3a View FIGURE 3 ); propodeum striate dorsally, vertical surface mostly punctate, shiny and finely sculptured medioventrally (reticulate and striate).

Male. Integument black with golden-yellow maculation on vertex, upper gena, lower face, nearly entire upper paraocular area, most of mandible, pronotal lobe, anterolateral scutum, axilla, posterolateral scutellum, ventral fore and middle femora, distal hind femur, most tibiae and tarsi, anterolateral T1, lateral and anterior T2, most T3–T5 except translucent distal margins, T6–T7 ( Fig. 5c–d View FIGURE 5 ). Lengths: head 2.2–2.3 mm; scutum 1.5–1.6 mm; forewing 5.6– 5.7 mm; body 4.6–5.5 mm. Structure. Head. Entire preoccipital carina well developed; omaulus broadly lamellate; fore and middle femora with spinose vestiture posteriorly; propodeum striate dorsolaterally, vertical surface partly punctate, most of vertical surface shiny and finely sculptured (reticulate and striate); T6–T7 posteromedian spines (T6 obtuse, T7 acute) (Fig. 6a–b); S1–S3 unmodified; S4 with a few black, setose hairs posteromedially (about 10 thick hairs, not a comb) (Fig. 6b); S5 with black, setose comb on most of distal edge (more than half distal edge, Fig. 6b–c); S6–S8 and gonocoxa resemble those of A. eritrinum (cf. Fig. 3d–g View FIGURE 3 ).

Distribution ( Fig. 7 View FIGURE 7 ). This new species is endemic to North-East Africa.
