Forewings transparent, basal cell large, costal area present (Pc+CP separated from CA), costal area lacking crossveins; forewing venation
The abdomen-legs-thorax and the genitalia subsets offered higher retention indexes (82 and 64 respectively) while the wing venation
subset offered lower retention index (Table 3).
Also, none of the three species of Lomatia recognised from early Eocene, middle Eocene and late Oligocene-early Miocene sediments in Argentina (reviewed by Gonzalez et al., 2007) were described with the support of cuticular evidence, and leaves with similar bipinnatisect/imparipinnate architecture and venation
occur elsewhere in Proteaceae.
This finding prompted a broadening of the scope of this contribution to include data on intra-specific wing venation
variability in extant species, in order to assist delimitation of related fossil species.
and setulae: Wing proportion 2.23, crossvein proportion 1.55-1.75.
Contributions to the morphology of Tectaria: venation
pattern of sterile and fertile leaves.
11) 3.6-3.8x as long as wide; venation
extending to about 0.6x length of wing, disc almost hyaline, mostly bare behind base of submarginal vein and densely setose elsewhere; the longest marginal seta 0.4-0.5x greatest width of disc.
Of the 25 remaining species, 12 present caeciliusid venation
, including the amber fossil species M.
The Charaxidae (RYDON, 1971; SALAZAR & CONSTANTINO, 2001) is a group of tropical cosmopolitan butterflies that can be distinguished, according to ACKERY, DE JONG and VANE-WRIGHT (1999), due to the shared characteristic homologous conditions: partial parapatagia or entirely sclerotized and shortly anastomosed Rs3 and Rs4 venation
Key words: Fagaceae, leaf venation
pattern, Quercus, stomates.
The genitalia and wing venation
were examined in 60% euparal solution or dried condition, respectively.
Thorax black; pronotum black, hexagonal, with a median carina strongly marked; pronotum with anterior margin straight, lateral-anterior margins straight, lateral posterior margin slightly sinuous, posterior margin grooved; scutellum brownish with slight central concavity, with horizontal grooves strongly marked; tegmina black, apical plexus of veins developed; hindwings hyaline with dark brown venation
, vein Cu1 not thickened at base; legs black; metathoracic tibia with two lateral spines (basal spine equal in size to spines in apical crown; apical spine larger than spines in apical crown); apical crown of spines on tibia consisting of two rows; basitarsus with two rows of spines covered by long setae; subungueal process present and quadrangular.
