Luodianasca
gen. n.
Type
species:
Luodianasca recurvata
n. sp.
Description.
Body robust. Head with eyes narrower than maximum width of pronotum. Vertex slightly produced medially, rounded anteriorly with transition to face rounded in profile; coronal suture distinct, extending to anterior margin of vertex. Face narrow and slightly convex in profile. Forewing with 3rd apical cell sometimes with short stalk. Hindwing with CuA bifurcated.
Abdominal apodemes weakly developed. Male pygofer short, terminally with few rigid microsetae on each side of lobe; ventral appendage absent. Anal tube large, process broad at base, subapically abruptly narrowing and turned anteriad. Subgenital plate broad basally, narrowing apicad, with large basolateral protrusion, setae of basal group unrecognizable, fine setae arising at extreme base of outer margin and macrosetae arranged in single row terminating subapically. Paramere serrate apically, preceded by setae and sensory pits. Connective lamellate with small caudal lobes. Aedeagal shaft tubular, preatrium long; without dorsal apodeme.
Etymology.
The name is derived from the
type
locality of the
type
species (Luodian,
Guizhou Province
). Gender: feminine.
Remarks.
Luodianasca
is similar to
Alebroides
Matsumura
,
Ghauriana
Thapa
,
Matsumurama
Thapa
,
Nikkotettix
Matsumura
and
Bhatasca
Dworakowska
in that the veins MP’ and RP in the forewing arise from m cell and CuA in the hindwing is branched apically. It is also similar to
Ghauriana
,
Bhatasca
and
Matsumurama
in having uniseriate lateral macrosetae of the subgenital plate, and also to
Bhatasca
in lacking the ventral pygofer appendage. The new genus differs from these genera in having the subgenital plate broad basally, the basal group setae not identifiable, anal tube appendage strongly developed, abdominal apodemes weakly developed and the coronal suture reaching the anterior margin of the vertex.
