Tylosema ronquisti Buffington


Tylosema ronquisti Buffington & van Noort

( Fig. 9 View FIGURE 9 )

Description. FEMALE. Head. Shiny on vertex and cheeks ( Fig. 9 View FIGURE 9 C), shagreened on frons and occiput ( Fig. 9 View FIGURE 9 E); setae only present on frons and occiput, area around ocelli glabrous. Antenna entirely dark brown/black, scape 1.8x length of radicle, short appressed setae present on all flagellomeres, 10 flagellomeres present, moniliform.

Mesosoma. Lateral aspect of pronotum entirely smooth, shiny, glabrous ( Fig. 9 View FIGURE 9 B). Mesopleuron entirely smooth; mesopleural carina comprised of a series of striations (not a single distinct carina); dorsal and ventral margins of mesopleural triangle clearly visible, setose ( Fig. 9 View FIGURE 9 B). Mesoscutum entirely shiny (lacking microsculpture) with few scattered setae present anteriorly between notaulices; notaulices incomplete anteriorly, parascutal impression obsolete; area between posterior junction of notaulices delineated by narrow impression ( Fig. 9 View FIGURE 9 C). Disk of scutellum smooth in center, gradually becoming more punctate and rugose around periphery; margin of disk with well-defined carina; disk gradually sloping ventrally ( Fig. 9 View FIGURE 9 C).

Metapleural-propodeal complex. Dorsal half of metapleuron with few long setae, ventral half glabrous ( Fig. 9 View FIGURE 9 B). Propodeum crenulate, sparsely covered by moderately long setae; area between propodeal carinae glabrous, smooth and shiny. Nucha smooth dorsally, slightly crenulate laterally, slightly protruding posteriorly.

Metasoma. Petiole striate no setae visible; obscured anteriorly by syntergum. Syntergum smooth and shiny; posterior portion lacking setae ( Fig. 9 View FIGURE 9 A). Entire metasoma, in lateral view, about as long as deep.

Wings. Pseudostigma strongly sclerotised such that no marginal cell is visible ( Fig. 9 View FIGURE 9 D).

Legs. Coxae and femora setose, dark brown/black; remaining portion of legs orange, evenly setose entirely to claws ( Fig. 9 View FIGURE 9 A).

MALE. Unknown.

Diagnosis. Separated from T. dayae by having rugulose sculpture around lateral and posterior margins (entirely smooth in T. dayae ) and the disk of the scutellum possessing a distinct posterior margin bounded by a carina (no carina in T. dayae ) and from T. nigerrimum by having a smoother lateral aspect of pronotum (areolate and rugulose in T. nigerrimum ).

Etymology. Named in honor of Fredrik Ronquist (Florida State University, Tallahassee, FL, USA).

Distribution. South Africa, Western Cape ( Fig. 13 View FIGURE 13 ).

Material examined. Holotype: SOUTH AFRICA. Western Cape Province. [first label] Langberg Farm, (3km 270o W Langebaanweg), 32o58.461’S 18o07.344’E, [second label] 22–30 Sep 2004, S van Noort, Malaise trap LW02-N2-M323, sand plain fynbos, [third label] SAM-HYM P0024401, [fourth label] holotype designation label. The holotype is a female mounted on a black card point. The holotype is in good condition. Deposited in SAMC.
