Cicchino, Armando C. & Valim, Michel P., 2008, Three new species of Formicaphagus Carriker, 1957 (Phthiraptera, Ischnocera, Philopteridae), parasitic on Thamnophilidae and Conopophagidae (Aves, Passeriformes), Zootaxa 1949 (1), pp. 37-50 : 40-41

Formicaphagus mariae Cicchino and Valim , n. sp.

( Figs. 3 , 14–15, 27–29 , 30 , 33)

Diagnosis: Both sexes more slender than the remaining two species of this group (two from Conopophagidae ), having the narrowest temporal, prothoracic, pterothoracic, and abdominal widths. Male genitalia distinctive, differing in the shape of endomeral complex, and Y-shaped (instead T shaped) penial sclerite. Female without posterior tergal setae VII–VIII and fewer setae on gonapophysis (6 on each side).

Male ( Figs. 3 , 14, 28 ): general habitus as in Fig. 14. Head longer than wide ( Fig. 3 ), wider than abdominal width. Preantennal region elongated, with lateral preantennal margins concave and apical portion noticeably produced (as in Fig. 27 ); ANW deeply emarginate. Dorsal anterior plate slightly longer than wide. Temples little expanded. Tergoposterior setae present on VI, 1, VII, 1–3 setae, and VIII, 1 seta on each side. Genitalia: mesosomal complex with margin slightly rounded at posterior margin and convergent in its sides, bearing two marginal sensilla on each side; penial sclerite Y-shaped, and paramera globular ( Fig. 28 ). Measurements (n=1): HL 0.410, ANW 0.071, POW 0.276, OW 0.371, ADPL 0.139, ADPW 0.115, PL 0.152, PW 0.219, PTL 0.162, PTW 0.286, AL 0.762, AW 0.390, GLT 0.212, GLM 0.195, GW 0.068, TL 1.362.

Female ( Figs. 15, 27, 29 –30,33): habitus as in Fig. 15. Head ( Fig. 27 ) and thoracic features much as for male. Tergoposterior setae on each abdominal hemitergites VI, 0–1, and VII, 0. Vulvar margin with 20 spinose and 9 slender setae ( Fig. 29 ), subgenital plate with 12 setae, and gonapophysis with 6 setae on each side. Measurements (n=1): HL 0.438, ANW 0.071, POW 0.276, OW 0.419, ADPL 0.146, ADPW 0.122, PL 0.171, PW 0.248, PTL 0.190, PTW 0.343, AL 0.990, AW 0.467, TL 1.638.

Prevalence: the prevalence of F. mariae n. sp. is very low, 1.694 % (1 out of 59 individuals examined).

Etymology: this species is dedicated in honour of Maria Ogrzewalska (Ph.D. student Departamento de Medicina Veterinária Preventiva e Saúde Animal of Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, Brazil), in recognition of her interest in collecting and making this material available.

Specimens examined: male holotype and female paratype deposited in ECIOC, BRAZIL: São Paulo; Pontal do Paranapanema , 03-II-2006, M. Ogrzewalska col.

Type host: Rufous Gnateater , Conopophaga lineata . Usually found close to the ground, in the undergrowth of humid Atlantic Forest in southeastern Brazil , northeast Argentina and Paraguay.
