The new species in our study can be distinguished from other species of Schizomyia associated with Bauhinia in having palpi with an obconical
first segment (it is spherical in S.
Doryopteris triphylla follows a pattern of development that is easily ascribed to the Adiantum type (Nayar & Kaur 1969), in which a more or less obconical
meristematic cell is established in early stages of development, the evolution of which lead to the acquisition of an apical multicellular meristem.
Seeds oblong to obconical
, angulate, light-brown, epidermis papillose striate, 2-2.5 mm long.
Spines 2.65-12.0 [micro]m long (Table 2; Erdtman, 1952), usually obconical
, often with a swollen base (Fig.
, considerably longer than distance from head to cruciform elevation; black with transversely arranged ochraceous irregular markings on tergites 2-8; irregularly covered with white pollinosity on tergites 2-8; densely covered with silvery hairs.
Astrocaryum chambira differs from the other species of subgenus Astrocaryum in having the biggest fruit, with epicarp glabrate when unripe, usually smooth, sometimes sparsely spinulose, greenish to yellowish when ripe, and a distinctive massive obconical
perianth, and in having yellowish spines on the petioles of juvenile plants.
Antenna (n = 5): scape obconical
0.09-0.10 mm long, pedicel globose 0.06 mm long, and flagellomeres binodal and tricircumfilar; nodes, internodes, and necks setulose; basal and distal circumfila of each flagellomere with loops regular in length; reduced mid-circumfila (Figure 6); flagellomeres 1 and 2 connate; flagellomeres 1 + 2, 0.43-0.48 mm long; flagellomeres 3 and 4, 0.20-0.21 mm long; flagellomere 5, 0.20-0.22 mm long; flagellomere 6, 0.20-0.23 mm long; flagellomeres 7-9, 0.20-0.22 mm long; flagellomeres 10 and 11, 0.20-0.21 mm; and flagellomere 12, 0.20-0.22 mm long with setulose apical process 0.05-0.07 mm long.
