Genus Macrophyllodromia Saussure and Zehnter, 1893
Type of genus: Pseudophyllodromia maximiliani Saussure, 1873 .
Diagnosis. The genus Macrophyllodromia consisting of relatively large cockroaches (about 20 mm length) with a broad, dark longitudinal band on the head stretching from interocular field to labrum (absent in M. nigrigena Hebard and M. nobile Anisyutkin) and a pair of dark longitudinal bands on the pronotum (very modified in M. multimaculata Lopes & Oliveira). Males without pheromonal tergal gland on abdomen, subgenital plate asymmetrical with obvious protrusions. Tegmina and wings in both sexes fully developed.
Distribution: Central and South America.
The genus Macrophyllodromia shows close relationship to Latiblattella Hebard, 1917, Antitheton Hebard, 1919, and Eurylestes Hebard, 1940 (after Rocha e Silva Albuquerque 1962).

Type material. Holotype male, Ecuador, Otongachi reserve, 00°19'15"S; 78°57'06"W, near the village of La Union del Toachi, 33 km E of Santo Domingo de los Colorados, elev. ca 850 m, piedmont evergreen woodland, 19–25 September 2009, Ľ. Vidlička & M. Kozánek leg., deposited at the Institute of Zoology SAS, Bratislava, Slovakia.
Description. General colour of body yellowish brown (Fig. 1 a).
Head with occiput pale, epicranium and vertex mostly black, but vertex over the ocelli with narrow irregular transverse yellow strip. Face yellow with broad longitudinal black band continued to labral suture. On clypeus band brown, but distinct. Genae black. Eyes and ocellar spots (fenestrae) yellowish. Maxillary palps yellowish, last joint brownish (Fig. 1 b). Antennae brownish, tenuous, longer than whole body.
Pronotum widest in caudal third. Two black longitudinal bands (widest caudally) beginning on front margin, not reaching hind margin of pronotum. Sides of pronotum yellowish translucent, with scattered fine but visible dark dots (Fig. 2 a). Tegmina and wings fully developed, folded and overlapping apex of abdomen. Veins reddish brown. Anal fields of forewings with eight anal veins, first vein with four rami. Interveinal areas in anal fields of forewings with narrow yellow stripes. Legs yellow, apical part of tibiae and tarsal segments on all legs black (Fig. 1 c). Tarsal joints with large distal pulvilli. Tarsal claws simple, unspecialized, between them well developed arolia with bilobed distal end. Antero-ventral margin of front femur armed with 18 heavy spines of type A (sensu Bey- Bienko 1950, Roth 2003).
Abdominal dorsal surface unspecialised. Supra-anal plate short, triangular, bilobed at apex (Fig. 1 d). Cerci elongated, composed of 15 distinctly separated segments (Figs. 1 d, e). Subgenital plate strongly asymmetrical and of complicated design (Fig. 1 e). Apical part divided into three protrusions. Protrusion on left side (LP) forming two large projections, the first extending straight back as a large, sharp horn with finely bifurcate apex (LP1), the second extending to the right as a very long, narrow rod-like sclerite (LP2), partly enclosed by small central growth (CG), and ending just right in deep groove of mitten-like right protrusion (RP) (Figs 1 e, 3a). Styli completely absent, protrusions apparently only representing projections of the subgenital plate.
Measurements. Holotype (mm): length of body 20.7, length of pronotum 4.4, width of pronotum 7, length of tegmen 21.4, width of tegmen 6.4.
Etymology. This new cockroach species named in honour of Professor Giovanni Onore, missionary, entomologist and President of the Otonga Foundation in Ecuador.
Differential diagnosis. Macrophyllodromia onorei sp. n. is similar to M. panamae in the length of the dark longitudinal bands of the pronotum (bands not reaching posterior margin of pronotum) but not in their form (Figs. 2 a, 2b). Structure of the subgenital plate is also similar in both species, but the central growth (CG) is markedly shorter in M. onorei (Figs. 3 a, 3b). The new species is similar to M. ecuadorana, M. nigrigena, M. nobile and M. amabile in the coloration of the pronotum (Figs. 2 c, 2d, 2e, 2j), but it is easily distinguishable from all those species in the presence and form of the dark longitudinal band on the face ( nigrigena and nobile have the whole face dark; see Figs. 2 d, 2e) interrupted with a narrow pale transversal strip over the ocelli. In M. ecuadorana and M. amabile this band is without interruption (Figs. 2 c, 2j).

Notes. In only five of Macrophyllodromia species have females been described. Several unnamed females also have been reported. Anisyutkin (2007) mentioned 4 females from 3 various localities in Ecuador. They probably represent at least two different species, but their assignment to the known species was not possible at that time. Roth & Naskrecki (2001) also mentioned an unknown female (probably a new species) from Costa Rica.
The transverse light stripe over the ocellar spots is characteristic for females of M. amabile and also some unnamed females from Rio Aguarico, Ecuador (Anisyutkin 2007). Macrophyllodromia onorei is the first species found in which the male has a strong transverse stripe over the ocellar spots.
