Sphingius longipes Gravely, 1931: 270 , fig. 19A–B; Majumder & Tikader, 1991: 148, figs 311–314.

Type material. Syntype Ƌ from INDIA: Kerala: Palakkad: Pattambi (formerly in Malabar district ): beside the traveller’s bungalow, leg. F.H. Gravely, 24–28 May 1930, deposited in NZC-ZSI (no register number), examined ( Fig. 10E View FIGURE 10 ) .

Justification of the transfer. Detailed examination of the syntype of S. longipes Gravely, 1931 revealed that it has the typical somatic morphology for Cithaeronidae Simon, 1893 ( Fig. 10 View FIGURE 10 A–D) and the diagnostic features of the monotypic cithaeronid genus Inthaeron Platnick, 1991 , as illustrated for Inthaeron rossi Platnick, 1991 , the type species of the genus: highly coiled embolus, and embolus with a fringed flange (compare Fig. 11 View FIGURE 11 A–C with Platnick & Gajbe 1994: figs 1–3). Based on these observations, we propose to transfer S. longipes to Inthaeron .

Diagnosis. The male of I. longipes comb. nov. can be separated from the male of I. rossi by the following combination of features: broad retrolateral tibial apophysis (narrow in I. rossi ), fringed flange with a prolateral twist (fringed flange with retrolateral twist in I. rossi ) and absence of a median apophysis ( I. rossi with highly reduced median apophysis) (compare Figs 10F View FIGURE 10 and 11 View FIGURE 11 A–C with Platnick & Gajbe 1994: figs 1–3). Females can be separated from the females of I. rossi by an anteriorly oriented long, median tongue-like plate ( Fig. 10F View FIGURE 10 ), which is absent in the latter species ( Gravely 1931; Platnick 1991: fig. 21).

Note. With the transfer of S. longipes , the total number of known Inthaeron species is increased to two, I. rossi and I. longipes comb. nov.; both species are known from both sexes.

Remarks. The ZSI collection has one glass bottle for this species labelled as “ Type ” (1513/18), containing a male specimen in good condition, with intact pedipalps. Gravely (1931) also described the female of this species ( Fig. 10F View FIGURE 10 ), but we could not trace any female specimen in the collection.
