Aedeagus of
Lesteva dabashanensis
Rougemont, 2000
(4, 6, 8, 10—GANSU: Dalijia Shan; 5, 9—HUBEI: Shennongjia; 7, 11—SICHUAN: Hailuogou): 4̅7—parameral view, 8̅11—lateral view; 4̅5—aedeagi with rolled apical lobes of the parameres (for details see the text); 6̅7̅aedeagi with disclosed apical lobes of the parameres (for details see the text). Scale bar: 0.2 mm.
Remarks.
The species was described by
Rougemont (2000)
from Shenxianhe (
1910 m
a.s.l), Langao Xian,
Shaanxi
. Measurements (n=27) of the specimens studied by me from
Gansu
,
Sichuan
and
Hubei
provinces: WH: 0.58–0.65; LH: 0.43–0.48; LA (on average): 1.55; LE: 0.20¯0.24; LT: 0.08¯0.10; LP: 0.61–0.70; WPMax: 0.65– 0.70; WPMin: 0.45–0.60; LEl: 1.10–1.25; WE: 1.20–1.50; WA: 1.15¯1.45; LAed: 0.65–0.75; TL: 3.20–3.82. Considerable variability of
L
.
dabashanensis
was observed in the coloration and proportions of the body, and in the shape of the apical part of the aedeagus. The coloration varies from yellow-brown to black; elytra unicolourous or with distinct yellow-brown to reddish brown transverse macula in first third of each elytron; antennomere yellow brown to brown, with yellow basis of antennomeres 1̄2, sometimes with fully yellow antennomeres 1̄2 or with paler apical three antennomeres; femora and tibiae yellow-brown to brown with yellow to yellow-brown apical parts; ocelli, mouthparts and tarsi yellow to yellow brown. The shape of the aedeagus is variable (
Figs. 4–11
) in the shape of its apex and apical portion of the parameres: with rounded apices, as the result of the rolling of setiferous lobes (compare
Figs. 4–5
and schematic Fig. 16a in
Rougemont 2000
) or with disclosed lobes, as in
Figs. 6–7
. The distribution of the species is illustrated in
Fig. 12
. Recently,
Rougemont (2017)
described
L. michaeli
Rougemont, 2017
based on two specimen with black forebody and “[…] apical margin of elytra narrowly brownish” (habitus as in
Fig
5
in
Rougemont 2017
), from Daba Shan range,
Hubei
(the
type
locality of it is indicated by white circle in
Fig. 12
). However, the study of the
holotype
and structure of its aedeagus (
Fig. 5
a in
Rougemont 2017
) leaves no doubt that it refers to
L
.
dabashanensis
, so that
L. michaeli
is here placed in the synonymy with it.
It is here recorded for
Sichuan and Gansu
for the first time.
