Pycnostigmus hoerikwaggoensis n. sp. Buffington & van Noort

( Fig. 6 )

Description. FEMALE. Head. Shiny without microsculpture around ocelli and on vertex ( Fig. 6 C); frons shagreened ( Fig. 6 E), cheeks weakly striate; setae present only on frons and occiput. Antenna entirely dark brown/black; scape 1.25x length of radicle, short appressed setae present on all 13 flagellomeres, filiform.

Mesosoma. Lateral aspect of pronotum stongly rugulose, shiny, with few sparse, long setae ( Fig. 6 B). Mesopleuron with numerous strigae above and below mesopleural carina; dorsal and ventral margins of mesopleural triangle clearly visible, setose ( Fig. 6 B). Mesoscutum entirely shiny (lacking microsculpture) with several scattered setae present over entire surface; notaulices complete, originating at anterior end of parascutal impression; area between posterior junction of notaulices delineated by teardrop-shaped impression ( Fig. 6 C). Disk of scutellum strongly rugulose posteriorly; margin of disk well defined by raised, sharp carina ( Fig. 6 C).

Metapleural-propodeal complex. Metapleuron with long, thin setae on dorsal half, glabrous on ventral half ( Fig. 6 B). Propodeum crenulate, sparsely setose to entirely glabrous; area between propodeal carinae weakly carinate, glabrous ( Figs 6 B & 6C). Nucha crenulate, not striate, protruding posteriorly ( Fig. 6 B).

Metasoma. Petiole striate without setae; petiole obscured anteriorly by syntergum ( Fig. 6 B). Syntergum smooth and shiny; posterior margin of syntergum, as well as T4, with a few long setae ( Fig. 6 A). Entire metasoma, in lateral view, about as long as deep.

Wings. Pseudostigma weakly sclerotised such that marginal cell is visible ( Fig. 6 D).

Legs. Coxae and femora setose, dark brown/black, non metallic; remaining portion of legs brown except for orange, non metallic joints; legs evenly covered with long, non appressed setae entirely to claws ( Fig. 6 A).

MALE: Unknown.

Diagnosis. Separated from P. mastersonae by the head and the mesosoma being non-metallic, from P. fossilensis by having the disk of the scutellum rugose (center smooth in P. fossilensis ), from P. rostratus by lacking the deep fovea on the lateral aspects of the pronotum (foveolate in P. rostratus ) and from P. i n c o g n i t o by having numerous strigae on the mesopleuron (few to no strigae in P. incognito ).

Etymology. Named in honor of the Table Mountain National Park. The original inhabitants of the Cape, the Khoi Khoi, called Table Mountain Hoerikwaggo –"sea mountain" or "mountain in the sea". The type locality, Constantiaberg, now forms part of Table Mountain National Park.

Distribution. South Africa: Western Cape ( Fig. 13 ).
