11. male head and pronotum, dorsal view; 12. male mesosternum and metasternum; 13–14. male terminalia, dorsal and lateral views; 15. female subgenital plate, ventral view; 16–18. epiphallus, dorsal, anterior and lateral views; 19–21. phallic complex, anterior, lateral and dorsal views. Scale bars = 1mm.
Description
Male
(
Figs 11–21
). The main morphological characters of the species are illustrated (
Figs 11–15
), and the phallic complex is newly described here. Epiphallus with crescent outer lophi nearly projecting in a 90° angle from bridge and rounded inner lophi; anchorae with apex obtuse; anterior projections with posterior sides nearly straight in lateral view; lateral plate with external margin concave in dorsal view and posterior sides convex in lateral view; posterior projection somewhat stout and backward reaching at posterior margin of outer lophi in lateral view; bridge distinctly divided in middle (figs 16–18). Phallic complex illustrated (figs 19–21). Ectophallic membrane with an extra, spoon-shaped sclerite (fig. 20).
Remarks
Sharing the same generic characters with other four, especially on male furculae upright large and lophi crescent, the species is transferred to
Longchuanacris
from
Caryanda
. A new scientific name of
L. viridus
Mao
et
Ou
is given for
C. macrofurcula
Mao
et
Ou, 2000
to avoid a junior homonym of
type
species
L. macrofurculus
Zheng
et
Fu, 1989
.
Distribution
China
: Yunnan (Tengchong, Baoshan, Dali).
