Descriptive remarks.
This species was known previously only from
one male
and
one female
from the
Cueva
de las
Maravillas in Llombai
(
Valencia
)
Wygodzinsky (1980)
.
Many
specimens (some of them incomplete or in poor condition) were collected from a nearby location.
Despite
minor differences in some of the characteristics from those presented in the original description, these specimens are assigned to
C. capolongoi
because the differences are minor; some are most likely due to intraspecific variability and others to the interpretation of some features with
OM
and now visualized with SEM
.
The size of the available specimens is slightly smaller than was given in the original description: the male length reaches
15 mm
and the female length is up to
17 mm
(up to
19.5 mm
in the
type
material). Cephalic setation is shown in
Fig. 1
. Macrosetae are moderately spiralized; the more twisted are those inserted in the coxae and pedicels, with 4 or 5 turns (
Fig. 2B
). The antennal apophyses of the male were illustrated in the original description, indicating that there are “two subapical projections closely adpressed to the glandular cone.” The SEM images reveal that the structure of the pedicellar apophysis is similar to related species (
Figs. 141–143
); the lateral plate-like projection has an indentation that resembles a division between two parts (
Fig. 143
) and is not adpressed to the glandular cone as it appears from some points of view (
Figs. 141
or 144), as it defines a median cavity (
Fig. 142
). The aspect of the antenna seen in
OM
(
Fig. 144
) is similar to Wygodzinsky’s illustrations, providing support that the examined specimens conspecific with
C. capolongoi
. In the available males, the apical part of the apophysis reaches the fifth joint of the flagellum.

Urotergite X of a male, detail of the hind border and posterolateral lobes with sensory pegs as visualized by OM. 148. SEM photograph of a posterolateral lobe of urotergite X showing some sensory pegs. Scale: 50 µm. 149. SEM photograph of a sensory peg. Scale: 7 µm. 150. SEM photograph of the paramera and stylets IX. Scale: 0.2 mm. 151. Urosternite VIII of a male. 152. Subgenital plate of a female. Scales: 0.1 mm except as noted.
The L/W ratios of the tibiae of available specimens are presented in
Table 2
. Each tibia has 2 dorsal, 1 lateral and 4 ventral spines; in some specimens, the metatibiae have some additional small basal spines (
Fig. 145
). The L/ W ratio of the metatibiae drawn by Wygodzinsky appears to be approximately 7, but in the recently found specimens, the tibiae are somewhat shorter (L/W about 5). This discrepancy can be explained by different assumptions: a) a high variability in this feature in
C. capolongoi
, with larger specimens like those studied by Wygodzinsky having longer tibiae; b) Wygodzinsky’s drawing of the tibia is not very precise; c) the specimens now available are not conspecific with
C. capolongoi
. The latter hypothesis is rejected by the large number of anatomic similarities between the specimens available and those in the original description and the geographic proximity of their localities.
Coletinia longitibia
n. sp.
has an L/W ratio very similar to Wygodzinsky’s drawings, but is different because of the different shape of the eighth urosternite in males and the higher number of sensory pegs in the tenth urotergite.
The posterior margin of the tenth urotergite of the male is straight, as originally described (
Fig. 146
). The number of sensory pegs in each lobe of the tenth urotergite is
4–5 in
the original description and
4–6 in
the available specimens. These sensory pegs were originally described as bulb-shaped and this shape as observed by
OM
is confirmed (
Fig. 147
). In SEM of
one specimen
, the pegs are subcylindrical, with striated tegument; these striations are subparallel and converge in a ventroapical furrow (
Figs. 9A
,
148, 149
). This shape and structure are very similar to those of other species that we have also observed with SEM (see
Figs. 9B and 9C
for
C. tinauti
and
C. intermedia
n. sp.
, respectively).
The tenth urotergite of the female fits the original description, slightly concave at the posterior border and with the disc covered irregularly with setae. The hind margin of the eighth urosternite of the male is protruding and convex (
Fig. 151
).
Paramera are long, approximately 6 times longer than wide, reaching the apical fourth of the tenth stylet (
Fig. 150
). The subgenital plate of the female is semielliptical, rounded posteriorly (
Fig. 152
), wider at the base than long (L/W about 0.85). The ovipositor is as originally described; the gonapophyses have 15–16 divisions. Males have 4–6 sensory pegs in the basal part of each cercus; the shape of these pegs is almost conical, more acute apically than those of the tenth urotergite (
Fig. 10
) but show the same striated tegument. The paracercus possesses a row of acute sensory spines.
