Zatypota mulunguensis Pádua & Sobczak sp. n.

(Figs 4A, B, C)

Type material. Holotype ♀. BRAZIL, Ceará: Mulungu, 4°18’40’’S, 38°58’05’’W, 14.xii.2015, parasitizing Anelosimus baeza spider ( Theridiidae ), (J.F. Sobczak and team legs), INPA .

Diagnosis. This species can be distinguished from all other Zatypota by the combination of the following characters: 1) lower face and frontal orbits yellowish white, with the frontal orbital stripe extending backwards beyond top of eye to curve slightly inwards behind ocelli; 2) occipital carina complete; 3) fore wing with 2rs-m short but distinct, clearly longer than broad; 4) propodeum with lateromedian longitudinal carinae quite strong, complete from anterior margin to posterior transverse carina; 5) propodeum with area petiolaris 2.3× broader than long; and 6) tergite I with lateromedian longitudinal carinae extending at least 0.9 of length of segment.

Description. Female. Body 5.2 mm; face 0.9× as broad as high (from supraclypeal suture to base of antenna), polished with rather coarse sparse setiferous punctures; malar space about 0.55× as long as basal mandibular width, subocular sulcus strong; occipital carina complete. Mesoscutum slightly deplanate; mesopleuron polished, glabrous, except for ventral 0.4 which is sparsely hirsute, slightly plan medially; mesosternum densely pubescent; metapleuron convex, anteriorly smooth with isolated, fine setiferous punctures. Propodeum dorsally rather flattened, fairly smooth centrally, rugulose posterolaterally; lateromedian longitudinal carinae quite strong, complete from anterior margin to posterior transverse carina; lateral longitudinal carinae discernible as distinct branches on posterior transverse carina, reaching until to posterior part of propodeal spiracle; area petiolaris 2.3× broader than long; pleural carina complete. Fore wing length 3.9 mm; cu-a distal to base of Rs&M by 0.5× its own length; base of 1m-cu separated from Cu1a by slightly less than the length of Cu1b; 2rs-m short but distinct, clearly longer than broad. Tergite I 1.5× as long as posteriorly broad, weakly granulate to rugulose, weakly polished, with lateromedian longitudinal carinae extending at least 0.9 of length of segment; and with oblique posterior grooves weakly impressed, slightly trans-striate; tergite II 0.85× as long as posteriorly broad, centrally from smooth and polished to granulostriate. Ovipositor 0.7× as long as hind tibia.

Coloration. Head black, lower face and frontal orbits yellowish white, with the frontal orbital stripe extending backwards beyond top of eye to curve slightly inwards behind ocelli; mouthparts whitish, except apex of mandibles black; antenna brownish, with scape, pedicel, first and second flagellar segments pallid, especially ventrally. Mesosoma reddish brown; propodeum with posterior region slightly blackish; anterolateral margin of mesoscutum and base of notaulus broadly whitish yellow; tegula and subalar prominence whitish; scutellum yellow whitish. Metasomal tergites and ovipositor sheath blackish brown; tergite I with indistinct orange marks, tergites II-V anterocentrally yellow whitish. Fore leg yellowish, with trochanteral segments, femur tibia with indistinct orange marks; mid leg similar, but with trochanter and femur proximally infuscate, femur distally whitish, tibia centrally whitish, basally and apically blackish, tarsus infuscate; hind leg with coxa and trochanter whitish with trochanter proximally and trochantellus distally infuscate; femur proximally just distal to centre infuscate, the area between yellowish, and the extreme distal apex white; tibia and tarsus blackish, the former with a narrow median white band, the basitarsus proximally pale. Wings hyaline; pterostigma brown. Ovipositor brownish with its apex pallid.

Male. Unknown.

Distribution. Brazil (Ceará state).

Etymology. The specific name refers to type locality, Mulungu in Ceará state, Brazil.

Comments. Zatypota mulungu sp. n. closely resembles Z. alborhombarta Gauld, 1991 mainly by lower face and frontal orbits yellowish white, with the frontal orbital stripe extending backwards beyond top of eye to curve slightly inwards behind ocelli; mesosoma reddish brown, anterolateral margin of mesoscutum and base of notaulus broadly whitish yellow; tegula and subalar prominence whitish. It differs from it principally by fore wing with 2rs-m short but distinct, clearly longer than broad and tergite I with lateromedian longitudinal carinae extending at least 0.9 of length of segment. Z. alborhombarta has the fore wing with 2rs-m broader than long and tergite I with lateromedian longitudinal carinae extending at least 0.4 of length of segment.
