Type
species:
Camptocladius ephemerae
Kieffer, 1924
, by original designation.
Diagnostic characters
: The straight gonostylus, elongate apical palp segment, bare wings, eyes and squama combined with extended costa will easily differentiate
Epoicocladius
adults from other genera in the subfamily Ortho- cladiinae. The ovoid thoracic horn and elongate tails on the anal lobe with the presence of numerous setae on most abdominal segments will differentiate the pupae. The larval habitat, body covered with strong setae and the strongly arched mentum with numerous teeth allows the larvae to be easily identified.
Emended diagnosis.
Based on the Chinese materials, the generic diagnosis of pupae and adult
Epoicocladius
(
Coffman
et al.
1986
,
Cranston
et al.
1989
) must be emended as follows. Pupae: three precorneals with variable length (pupal exuviae of
E. ephemerae
(Kieffer)
from
China
and Europe). Male: wing length up to
1.10–2.48 mm
; AR 0.65–2.21 (
2.21 in
E
.
itachisecundus
(Sasa
et

; anal lobe weakly to strongly developed; anal point absent or present, if present, triangular with rounded or needle shaped apex (
