Extended diagnosis. Males of this species are distinguished from those of the large majority of Heteropoda species with a more or less distinctly pointed conductor tip by the distally widened conductor; H. schwalbachorum can be distinguished from species with a distally widened conductor, namely H. erythra Chrysanthus, 1965 and H. hirsti Jäger, 2008 by the absence of a proximal conductor apophysis, and from H. squamacea Wang, 2009 and H. jasminae Jäger, 2008 by the absence of a distinct bifurcation of the distal conductor (cf. Jäger 2008: figs 340–349, 361–365). Females of H. schwalbachorum are similar to those of H. amphora Fox, 1936 (cf. Jäger 2001: figs 16h–j) in having a broad median septum and an overall similar internal duct system, but can be distinguished by the presence of lobal wings (as anteriomedial extensions of the lateral lobes) ( Fig. 1D : LW) and a transverse rim in the median septum ( Fig. 1D : R) as well as the transversely oriented oval spermathecae ( Fig. 1E : S) (lobal wings and transverse rim absent as well as longitudinally oriented spermathecae in H. amphora ).

Description. Male: see Jäger (2008); Figs 1A–C .

Cheliceral furrow with 3 anterior teeth with median largest, and 4 posterior teeth, and with ca. 35 denticles in slightly elongated patch close to anterior teeth; margins close to fang base with one bristle. Palpal claw with 7 teeth. Sternum, ventral coxae and femora, distal legs as well as frontal chelicerae with long setae, otherwise with shorter setae.

Epigynal field with discontinuous anterior bands. Lateral lobes (LL) widely separated from each other. Median septum (MS) wide, covered partly by lateral lobes medially and posteriorly. Internal duct system with anterior part of first winding medially touching each other, looped apex rounded, situated at the margin of the first winding, posteriolaterad. Spermathecae large and oval, separated from each other by their diameter. Fertilization ducts (FD) arising posterio-medially, laterad ( Figs 1D–E ).

Colouration in ethanol: yellowish- to slightly reddish-brown. Chelicerae reddish-brown; dorsal prosoma bright reddish-brown with cuticular radial pattern and vivid pattern consisting of dark hairs. Sternum, ventral coxae and femora, gnathocoxae and labium pale yellowish, gnathocoxae and labium proximally pale yellowish-brown. Legs pale yellowishbrown with distal parts slightly darker, spine bases surrounded by deep yellowish-brown spots; ventral femora dotted. Dorsal opisthosoma dark-brown, with three median pairs of dark spots and a dark transversal wave-shaped pattern near the spinnerets. Ventral opisthosoma with bright trapezoid-shaped pattern in the median part, otherwise dark-brown without distinct pattern. Spinnerets yellowish-brown.

Distribution. China (Hainan Province) ( Fig. 2 ).
