Revised diagnosis.
A subgenus of
Parapseudoconnus
showing the following differences in relation to
Parapseudoconnus
s. str.
: prothoracic hypomeral ridges complete; anterior margins of mesocoxal cavities distinctly demarcated by carina; mesocoxal sockets located on mesal surface of mesocoxal projections and therefore not visible in ventral view; posterior lobes of mesocoxal projections absent; and the internal armature of the aedeagus with long and slender flagellum projecting distally beyond the median lobe.
Redescription.
Body of male (Fig. 45) strongly convex, elongate and relatively slender, with long appendages, vestiture distinct but unremarkable.
Head (Fig. 42) as in
Parapseudoconnus
s. str.
, without important differences.
Prothorax (
Fig. 33
) differs from that of
Parapseudoconnus
s. str.
in ventral structures: internal parts of hypomera demarcated laterally by complete hypomeral ridges (
Fig. 33
;
hyr
), and pronotosternal sutures (
Fig. 33
;
nss
) strongly curved laterally, so that the basisternal part of prosternum is expanded laterally.
Mesoventrite (
Fig. 33
) as in
Parapseudoconnus
s. str.
, except for indistinctly demarcated asetose impressions (
Fig. 34
;
ai
), presence of distinct carinae demarcating antrerior margins of mesocoxal cavities (
Fig. 34
;
mscc
), and mesocoxal projections (
Fig. 34
;
mcp
), which conceal mesocoxal sockets (
Fig. 34
;
mscs
) located on their mesal margins; posterior lobes of mesocoxal projections absent.
Metaventrite (
Fig. 34
) as in
Parapseudoconnus
s. str.
, except for broader metaventral intercoxal process (
Fig. 34
:
mtvp
).
Elytra (Fig. 45) as in
Parapseudoconnus
s. str.
Legs (
Figs. 21
,
33–34
) long; femora clavate, tibiae slender, tarsi moderately elongate.
Abdominal sternites in the only studied specimen not preserved.
Aedeagus (
Figs. 35–36
) partly damaged or distorted in studied specimens, so the shape of its distal part is not possible to describe, with thin walls and complex, asymmetrical internal armature composed of a system of irregular sclerites, with long flagellum projecting distally beyond median lobe.
Distribution and composition.
Three species are known to occur in the northern part of
Peru
.
Remarks.
Specimens of
Parapseudoconnus
belonging to
Neuraphomimus
are poorly preserved in NHMW and only the male of
P. simulator
is nearly intact, while the
type
specimens of the remaining two species are partly or nearly completely damaged. The aedeagi, partly damaged or distorted during previous studies, are fragile and they were remounted only to ensure their safety and visibility in the mounting medium (previously the aedeagi were mounted in such a way that they were barely visible), as described in the Materials and Methods section. No attempts were made to obtain preparations with the aedeagi in a perfectly dorsal or ventral position, which would have required additional manipulations and might have caused further damage. Therefore, the aedeagi are here illustrated as they are embedded, not necessarily in dorsal or lateral aspects. In order to identify new specimens their aedeagi must be studied in various positions to carefully examine the shape of internal armature and compare it with that showed in
Figs. 35–36
and in Franz (1980; Fig. 205).
