Tylosema nigerrimum Kieffer

( Fig. 7 View FIGURE 7 )

Tylosema nigerrimum Kieffer 1905:112 . Type species by monotypy.

Redescription. holotype MALE: Head. Shagreened on vertex, cheeks ( Fig. 7 View FIGURE 7 B) frons and occiput ( Fig. 7 View FIGURE 7 E); sparse setae present on frons, occiput, genal area and area around ocelli. Antenna entirely dark brown/black; scape 1.7x length of radicle, short appressed setae present on all 13 flagellomeres, moniliform.

Mesosoma. Lateral aspect of pronotum strongly areolate, rugose, with few sparse setae ( Fig. 7 View FIGURE 7 B). Mesopleuron entirely rugulose/areolate dorsal of mesopleural carina; gently shagreened below mesopleural carina ( Fig. 7 View FIGURE 7 B); dorsal and ventral margins of mesopleural triangle clearly visible, setose, with distinct grooves following contours of anterior margin of mesopleural triangle ( Fig. 7 View FIGURE 7 B). Mesoscutum shagreened with moderate setation present; notaulices incomplete anteriorly, parascutal impression obsolete; area between posterior junction of notaulices delineated by a ‘pinched’ area ( Fig. 7 View FIGURE 7 C). Disk of scutellum shagreened and evenly rounded; margin of disk well defined by a distinct carina ( Fig. 7 View FIGURE 7 C).

Metapleural-propodeal complex. Metapleuron with a few scattered setae along posterior margins ( Fig. 7 View FIGURE 7 B). Propodeum crenulate with few long setae; area between propodeal carinae weakly carinate, glabrous. Nucha crenulate, not striate, slightly protruding posteriorly ( Fig. 7 View FIGURE 7 B).

Metasoma. Petiole obscured anteriorly by syntergum. Syntergum smooth and shiny; posterior portion lacking setae. Entire metasoma, in lateral view, 1.67x longer than deep.

Wings. Pseudostigma weakly sclerotised such that the marginal cell is visible ( Fig. 7 View FIGURE 7 D).

Legs. Coxae and femora setose, dark brown/black; rest of legs brown except for pale brown joints; evenly setose entirely to claws ( Figs 7 View FIGURE 7 A and B).

FEMALE. Unknown.

Diagnosis. Separated from T. dayae by having the scutellar disk shagreened and distinctly margined posteriorly (smooth and lacking margin in T. dayae ) and from T. ronquisti by having a rugulose/areolate lateral aspect of the pronotum (smooth in T. ronquisti ) and a shagreened mesoscutum (smooth in T. ronquisti ).

Distribution. Northern Africa: Algeria ( Fig. 12 View FIGURE 12 ).

Material examined. Holotype: NORTHERN AFRICA: [first label] Algeria, Tebessa, 26-4-(18)98, deGaulle, [second label] Tylosema nigerrimum K (handwriting unknown), [third label] HOLOTYPE, [fourth label] Museum Paris [see inset Fig. 7 View FIGURE 7 A for labels]. The type is a male, in good condition (c.f. Fig. 7 View FIGURE 7 A), having been remounted on a white card; the left hind leg and forewing have been mounted separately from the body. Deposited in MNHN.

Additional material. None.
