(Figs 62–64)
Holotype. Female. BRAZIL: Rio de Janeiro, January 1939, YelFevServ MESBrazil R. C. Shannon (USNM, paratype of L. varius).
Paratype. BRAZIL: Paraná, Piraquara, Mananciais de Serra, 25°29’S 48°59’W, 1050m, 22 January – 4 February 2006, A. Aguíar, am. Malaise trap (1 3, DZUP).
Diagnosis. The female of L. tupi is unique among all female Liosphex in showing the combination of the following characters: Distal margin of the mid- and hindtibia with a group of stout and thick bristles (as in Fig. 23); subantennal black marking not restricted to subantennal sclerite, reaching laterally down to cover the dorsal margin of clypeus (as in Fig. 17); and brownish mid- and hindlegs.
The male of L. tupi is unique among all male Liosphex by showing the following character combination: Subantennal black marking not restricted to subantennal sclerite, reaching laterally down to cover the dorsal margin of clypeus (as in Fig. 17); anterior margin of pronotum notched (as in Fig. 19) and brownish mid- and hindlegs.
Description of the female. Head (Fig. 62): Maximum width in frontal view 1.7 mm. UID 1.4× LID. Flagellomeres short (flagellomere II 2.9×, flagellomere VII 1.9× as long as wide). Apical bristles present on flagellomeres I–V, longer bristle on flagellomere I 0.6× its length. Lateral ocellus distad from eye by 2.4× its longitudinal diameter. OOD 1.1×, IOD 1.1×, MOD 1.0× LOD.
Mesosoma: Length of mesosoma: 3.3mm. Anterior margin of pronotum with a median notch (as in Fig. 19).
Wings: Maximum length of forewing: 7.5mm, 2.25× as long as mesosoma. Forewing 1cu-a slightly curved, basal section vertical, distad M by at least 2.2× its length. M-cu slightly curved. 1Rs 2.25× as long as high, its basal angle clearly smaller than 90° (Fig. 9). Rs of hindwing reclivous.
Legs: Forebasitarsomere short, length of antennal cleaner 0.4× its length. Mid- and hindfemur with a few bristles spread over its distal dorsal area. Mid- and hindtibia with a group of stout and thick bristles at the apical margin (as in Fig. 23).
Metasoma: Tergite I 1.9× as long as wide.
Color (as in Figs 63–64): Basically dark brown to black. Subantennal black marking not restricted to subantennal sclerite, reaching laterally down to cover the dorsal margin of clypeus (as in Fig. 17). Ventral side of antennae, area within eye notch, clypeus (except its medioventral part), labrum, gena, posterior margin of pronotum, tegula, posterior section of propodeum, forefemur (except two longitudinal stripes on its inner and outer side), foretibia, basal quarter/third of mid- and hindtibia, tibial spurs, posterior section of metasomal segment I, first quarter/third of metasomal segment II and anterior half section of metasomal segment III stramineous. Wings brownish, more intensively on distal section. Wing veins brown.
Pilosity: Body, including legs, largely covered with dense setae. Setae lacking on following structures: occiput, ventrolateral side of pronotum, ventrolateral side of scutellum, median area of mesepisternum, ventral part of metepimeron, anteroventral of metepisternum, median part of lateral side of propodeum and posteroventral half of hindfemur.
Description of the male. Head, mesosoma and metasoma as in female except the following:
Head: Maximum width in frontal view 1.4 mm. UID 1.5× LID. Flagellomere II 2.3×, flagellomere VII 1.7× as long as wide. Apical bristles present on flagellomeres I–VI, longer bristle on flagellomere I 0.7× its length.
Mesosoma: Length of mesosoma: 2.4 mm.
Wings: Maximum length of forewing: 5.9 mm, 2.45× as long as mesosoma. Forewing 1cu-a distad M by at least 1.8× its length. 1Rs cell 2.15× as long as high.
Legs: Mid- and hindtibia without a group of stout and thick bristles at its apical margin. Tarsomeres II–IV with plantulae.
Metasoma: Tergite I 1.7× as long as wide.
Life history. Nothing is known.
Etymological note. ‘ Tupí ’ is the name of an indigenous language which was spoken in a wide area all along the Brazilian Atlantic coast before and during the conquest and colonization by the Portuguese; it is a noun in apposition.
Note. The holotype of L. tupi was part of the original type series of L. varius Townes, 1977. This species shares most of the main diagnostic features with L. guarani, but the completely different coloration makes it more likely that this specimen is to be treated as a valid species. The overall coloration is not simply darker than in L. guarani, it shows furthermore a completely different pattern on the clypeus, legs and wings.
