Description
. Male. General color yellowish brown, as in
Fig. 11C–F
. Surfaces smooth and lustrous; punctuation absent. Head wide and rounded (
Figs. 10
A, 11D, F); ocellar spots large; distance between eyes about 1.2 times of the eye length; distance between antennal sockets about 2.5–2.6 times of the scape length (
0.5 mm
) (about
2.2 in
specimen from
Sri Lanka
, scape length—
0.6 mm
); approximate length ratio of 3rd–5th segments of maxillary palps 1.2–1.3: 1: 1.3–1.4. Pronotum as in
Figs.10
B, 11C, E. Tegmina and wings completely developed, surpassing abdominal apex, rounded apically (
Fig. 11C
). Anterior margin of fore femur armed according to the
type
B, with 5 spines, including 1 apical one (
Fig. 10
C). Fore tibiae distinctly thickened distally (
Fig. 10
C). Structure of hind tarsi (
Fig. 10
D): metatarsus a little longer than other segments combined, with 2 unequal rows of spines along lower margin [exterior row (
Fig. 10
D,
e.r.
) consists of 27–28, interior one (
Fig. 10
D,
i.r.
)—13 spines (35 and 17 spines respectively in the specimen from
Sri Lanka
)]; 2nd and 3rd segments with 6–8/5 and 5–6/2 spines in exterior and interior rows respectively (9/5 and 6/2 spines—in specimen from
Sri Lanka
); other segments without spines along lower margin; metatarsus and 2nd–3rd segments with small apical euplantulae, 4th segment with larger euplantula (
Fig. 10
D); 2nd–3rd segments with euplantulae bordered with 2–4 "additional spines" (
Fig. 10
D,
a.s.
); claws symmetrical, simple; arolium well developed. Fore and middle tarsi similar to hind ones, but comparatively shorter. Anal plate as in
Fig. 10
E, F, with medial incision more or less expressed; paraprocts (
Fig. 10
G) and hypandrium (
Fig. 10
H) usual for the genus (
Roth 1981
;
Anisyutkin 2006
).

, males [A–H, J–V—specimens from Sri Lanka (C, D, G, J, L–N, Q–S) and South India (A, B, E, F, H, K, O, P, T–V)] and female (I).

; J, K—right phallomeres from above; L, O—sclerite L2D from above; M, N, P—apical part of sclerite L2D from above (M, P) and below (N); Q–S—sclerite L3; T–V—apical part of sclerite L3. Dotted area shows membranous parts. Abbreviations:

Male genitalia (
Fig. 10
J–V). Right phallomere (R+N) (
Fig. 10
J, K) with sclerite R1T thin and weakly sclerotized, caudal part of sclerite R1T reduced, only part situated in front of sclerite R2 present, densely covered with bristles; R2 straight; R3 long, with cranial part rod-like and caudal part curved; R4 substituted with membranous lobe; R5 large and strongly sclerotized, situated apart of other sclerites of right phallomere. Sclerite L2D (L1) divided into basal and apical parts (
Fig. 10
O, L); basal part strongly widened cranially, with "bent outgrowth" at caudal end (
Fig. 10
L, M, O, P,
b.o.
), sometimes with small rounded "additional sclerite" under basal part of L2D (
Fig. 10
L,
a.scl.
); apical part in shape of flattened, plate-like sclerite, with cranially prolonged "ventral projection" (
Fig. 10
M, N, P,
v.pr.
), and "apical tooth" in specimen from
Sri Lanka
(
Fig. 10
L–N,
ap.t.
); bristles absent. Sclerite L3 (L2d) without basal subsclerite; "folded structure" distinct, bristles absent (
Fig. 10
Q–S,
f.s.
); apex of L3 with comparatively larger "small tooth" (
Fig. 10
Q–V,
s.t.
) and more or less expressed "apical crest" (
Fig. 10
Q–V,
ap.cr.
), groove hge absent. Sclerite L4U (L3d) weakly sclerotized, elongated.
Variations
. Two specimens from South
India
are very similar in their external morphology, but the specimen from
Sri Lanka
differs in the darker coloration (cf.
Fig. 11C
and
Fig. 11E
), the larger size, the more numerous tarsal spines and the following details of the male genitalia: the shape of right phallomere (compare
Fig. 10
J and
Fig. 10
K) and the apical part of sclerite L3 (compare
Fig. 10
Q–S and
Fig. 10
T–V), and in the apical part of sclerite L2D (compare
Fig. 10
O, P and
Fig. 10
L–N).
Female. Typical for the genus (
Bey-Bienko 1969
;
Anisyutkin 1999
,
2006
), with the tegmina being reduced to the lateral flaps (
Fig.
10
I).
Measurements (mm). Head length: male 2.5–2.7, female 3.1; head width: male 2.6–2.9, female 3.5; pronotum length: male 4.0–4.5, female 4.4; pronotum width: male 5.4–6.0, female 6.8; tegmen length: male 14.0–15.2, female 3.0; tegmen width (in males—in place where
CuP
running into posterior margin of tegmen; in female—maximal width): male 4.6–5.0, female 1.8. Larger measurements attributed to specimen from
Sri Lanka
.
Note.
C. characterosa
was described in the genus
Epilampra
(
Walker 1868, p. 209
) from Bengal. Later, K. Princis described
C. tranquebarica
(
Princis, 1951
)
, also in the genus
Epilampra
, from South
India
(
Princis 1951
).
L. Roth (1981)
treated
C. tranquebarica
as a junior synonym of
C. characterosa
referring to the latter species as occurring both in
India
and in
Sri Lanka
. Species of the genus
Calolamprodes
can be distinguished by fine details in the somatic morphology and the male genitalia (
Anisyutkin 2006
). Unfortunately, the available descriptions of
C. characterosa
and
C. tranquebarica
are not detailed enough. Therefore, it is possible that both species and the specimen from
Sri Lanka
described above are not conspecific. Further studies based on a more representative material are required to resolve this problem.
