Type
species.
Alluropus demangei
Silvestri, 1911
(by monotypy). This species was synonymized with
A. calcaratus
(Pocock, 1891)
(former
Rhysida calcarata
) by
Siriwut
et al.
(2018: 1029)
.
Diagnosis.
Median tooth of labrum well developed. Forcipular tooth-plates present, trochantero-prefemur with well-developed process (
Fig. 111
). Tergites lacking longitudinal keels. Sternites with paramedian sutures which may be incomplete. LBS 7 with spiracles, the spiracles with atrium (fig. 21J in
Siriwut
et al.
2018
). Legs with tarsal spur(s), legs 1 with prefemoral spur (
Fig. 111
). Coxopleural process normally developed, with spines (
Fig. 110
). Prefemur of the ultimate leg with numerous spines ventro-medially and ventro-laterally (not with “a row of shallow tubercles” as written in
Edgecombe & Bonato 2011: 402
). This prefemur with well-developed corner spine of characteristic shape: long and enlarged in males (
Fig. 110
) and visibly smaller, comb-like in females (
Fig. 112
, fig. 22H in
Siriwut
et al.
2018
). Ultimate tarsus
1 in
males considerably swollen, with short, blunt dorsodistal projection (
Fig. 110
) followed by a disproportionately slender tarsus 2; pretarsus well-developed, with accessory spines.

Remarks.
Treated as a genus in
Edgecombe & Bonato (2011: 402)
,
Siriwut
et al.
(2018: 1005)
. The latter authors wrote in the Diagnosis of
Alluropus
(p. 1029): “… leg 1 with prefemoral … spurs. … Ultimate legs with male secondary sexual characters, such as swollen structure of tarsus 1 and dorsomedian projection [= corner spine] on prefemur” and (p. 1032): “The original description of
R. calcarata
also indicated characteristics of
Alluropus
, such as … and a prefemoral process on the ultimate legs that has not been reported in most South-East Asian
Rhysida
such as
R. longipes
,
R. singaporiensis
,
R. immarginata
and
R. monticola
”. Based on re-investigation of ZMMU’s material of both
Rhysida
(see Remarks above) and
Alluropus calcaratus
(Pocock, 1891)
—an adult female
ca
30 mm
long from Central
Laos
(Rc 7161), mentioned by
Schileyko (2007: 83)
as
Rhysida calcarata
Pocock, 1891
—we confirm these characters as diagnostic for
Alluropus
. None of the re-studied specimens of
Rhysida
(from either South-East Asia or the Neotropics, see above) have a prefemoral spur on leg 1 or a corner spine on the ultimate prefemur (
Fig. 107
). The re-studied specimen of
Alluropus calcaratus
has a coxopleural process of medium length with apical and subapical + lateral (or posterior coxopleural?) spines (i.e. as in the corresponding pictures of
Siriwut
et al.
2018
), relatively short ultimate legs, the prefemur with spines and a very characteristic comb-like corner spine (figs 22G, 22H of
Siriwut
et al.
2018
). These characters are virtually identical to those of females of
A. calcaratus
as presented in
Siriwut
et al.
(2018)
.
