Zatypota baezae Pádua & Sobczak sp. n.

(Figs 3A, B, C, D)

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 with triangular marks below antennal insertion and frontal orbits yellowish white, with the frontal orbital stripe extending backwards beyond top of eye to curve slightly inwards behind ocelli; 2) lower face with a longitudinal carina centrally; 3) occipital carina complete; 4) fore wing with 2rs-m short but distinct, clearly longer than broad; 5) propodeum with lateromedian longitudinal carinae quite strong, complete from anterior margin to posterior transverse carina; 6) propodeum with area petiolaris 1.6× broader than long; and 7) tergite I with lateromedian longitudinal carinae extending at least about 0.4 of length of segment.

Description. Female. Body 4.1 mm; face about 1.0× as broad as high (from supraclypeal suture to base of antenna), weakly polished with rather coarse sparse setiferous punctures, with a longitudinal carina centrally; malar space about 0.6× as long as basal mandibular width; occipital carina complete. Mesoscutum slightly deplanate; mesopleuron polished, glabrous, except for ventral 0.4 which is sparsely hirsute; mesosternum densely pubescent; metapleuron convex, smooth with isolated, fine setiferous punctures apically. Propodeum dorsally rather flattened, smooth centrally, weakly 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, not reaching posterior margin of propodeal spiracle, extending at least 0.5 of length until propodeal spiracle; area petiolaris 1.6× broader than long; pleural carina complete. Fore wing length 3.2 mm; cu- a distal to base of Rs&M by 0.4× its own length; base of 1m-cu separated from Cu1a by a distance equal to the length of Cu1b; 2rs-m short but distinct, clearly longer than broad. Tergite I about 1.3× as long as posteriorly broad, granulate to rugulose in the lateroapical margin and weakly granulate to rugulose posteriorly, weakly polished, with lateromedian longitudinal carinae extending at least 0.4 of length of segment; and with oblique posterior grooves weakly impressed, slightly trans-striate; tergite II 0.7× as long as posteriorly broad, centrally from smooth and polished to granulostriate. Ovipositor about 0.9× as long as hind tibia.

Coloration. Head black, lower face with triangular marks below antennal insertion 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 black apex of mandibles; antenna brownish, with scape, pedicel, first and second flagellar segmets pallid, specially ventrally. Mesosoma orange, with anterolateral margin of mesoscutum and base of notaulus broadly, tegula and subalar prominence, scutellum posteriorly and postscutellum yellow whitish. Metasomal tergites and ovipositor sheath blackish brown blackish; tergite I with indistinct yellow marks, tergites II-V anterocentrally yellow whitish. Fore leg and trochanter yellowish pale, with femur, tibia and tarsus orange pale; mid leg with coxa pale yellowish, femur and tibia orange with indistinct yellowish pale marks, tarsus orange and darker apically; hind leg with coxa and trochanteral segments whitish with trochanter proximally infuscate; femur darkish orange with apex pale yellowish apically; tibia blackish brown, with a narrow median white band, tarsus darkish orange, darker apically. Wings hyaline; pterostigma brown. Ovipositor brownish.

Male. Unknown.

Distribution. Brazil (Ceará state).

Etymology. Named after host.

Comments. Zatypota baezae sp. n. closely resembles Z. riverai Gauld, 1991 and Z. solanoi Gauld, 1991 mainly by having head black with triangular marks below antennal insertion and frontal orbits whitish, but differs both by presence of a longitudinal carina in the lower face and tergite I with indistinct yellow marks, tergites II-V anterocentrally yellow whitish (lower face without longitudinal carina and metasomal tergites entirely dark brown in Z. riverai and Z. solanoi ).
