Mendozamiris
Carpintero & Chérot
,
n. gen.
Diagnosis.
Brownish to greyish yellow with red brown marbled
Phytocoris
-like patches. Frons rounded and narrowly striate with oblique, dark brown grooves. Vertex slightly sulcate medially, without carina. Eyes contiguous to pronotal collar. Labium reaching middle of abdomen. Pronotal disk roughly punctate, with superficial, shallow but relatively wide punctures. Pronotal collar and area of callosities obviously striate in males, narrowly striate in females. Humeral angles round, posterior margin of disk relatively straight, lateral margins strongly concave in females (a character state related to brachypterism), less concave in males. Scutellum elevated, laterally striate and practically impunctate. Mesoscutum uncovered. Dorsal pilosity sparse, with very short, prostrate, white setae (black on modified cuneus of female), practically glabrous in dorsal view at low magnification. Hemelytra roughly punctate with superficial, shallow but relatively wide punctures. Female brachypterous, apical part of corium reduced, cuneus tilted, oval, ivory white, membrane limited to a translucent area.
Type
species:
Mendozamiris chiquillanes
n. sp.
Etymology.
After “Mendoza”, the province from
Argentina
where the new genus was discovered and “
Miris
”, the
type
genus of the tribe.
Discussion.
Mendozamiris
differs from all genera of the
Phytocoris
complex (
Adphytocoris
Carvalho & Gomes, 1969
,
Euphytocoris
Poppius, 1914
,
Gracilamiris
Stonedahl & Henry, 1991,
Miridius
Fieber, 1858
,
Neosapinnius
Wagner, 1960
,
Phytocoridea
Reuter, 1906
,
Phytocoris
Fallén, 1814
,
Phytocorisca
Carvalho & Fontes, 1972
,
Sanluiza
Carvalho, 1992, and
Vissosamiris
Carvalho, 1987
) by the dorsal punctation.
Mendozamiris
has a distinctly punctate pronotum and an elevated scutellum being relatively similar to
Incamiris
Carvalho & Ferreira, 1972
. It is easily separated from this Peruvian genus by its narrow and shallow, reduced but obviously present hemelytral punctation (the hemelytra of
I. peruviensis
are smooth) and its less elongate habitus.
Mendozamiris
differs from
Derophthalma
Berg, 1883
by the elongated male habitus, the oblique (and not vertical) head and the notably anteriorly narrow pronotum. The mandibular plate of
Minasmiris
Carvalho, 1980
is visible in dorsal view and not visible in
Mendozamiris
. The eyes of
Perumiris
Carvalho, 1987
are not contiguous to the pronotal collar and are contiguous in
Mendozamiris
.
Perumiris
and
Quichuamiris cochabambensis
Carvalho, 1974
differ also by their more rounded, less elongated habitus. The females of
Stittocapsus
spp. are brachypterous, however the two genera differs by the habitus. The scutellum of
Stittocapsus
is not elevated; the dorsal punctation is narrower and less deep than in
Mendozamiris
, particularly on the pronotal disk and hemelytra, where the punctation is nevertheless slightly stronger (it is not the case in
Mendozamiris
). The dorsal pilosity of
Stittocapsus
is limited to prostate, white, silky setae and its vertex lacks a sulcus, whereas
Mendozamiris
has two different setae on the hemelytra and the vertex is sulcate.
