Figs 8 , 10

Diagnosis

This new species is similar to H. bawanglingensis sp. nov. ( Fig. 1A–C ) and H. strasseni Strand, 1915 ( Jäger 2014: figs 130–135) in having a freely median septum and an anterior part of IDS with more than two windings up to the turning point, but can be distinguished from the latter by the following characters: (1) anterior bands indistinct (distinct in H. bawanglingensis , and integrated in H. strasseni ); (2) median septum almost as long as epigynal field (two thirds in length of epigynal field in H. bawanglingensis and H. strasseni ); (3) median margins of lateral lobes only gently curved (distinctly curved in H. bawanglingensis and H. strasseni ); (4) parts of IDS with glandular pores anteriad (mediad in H. bawanglingensis , posteriad in H. strasseni ) ( Fig. 8A–C ).

Etymology

The specific name is derived from the Latin adjective, ʻ longus ʼ (-a, -um), meaning long, referring to the median septum of epigyne in ventral view.

Measurements of palp and legs: Palp 7.0 (2.0, 1.2, 1.3, –, 2.4); I 26.8 (7.0, 2.9, 7.0, 7.2, 2.4); II 28.4 (7.5, 2.7, 7.7, 7.8, 2.5); III 24.0 (6.6, 2.5, 6.0, 6.4, 2.2); IV 26.8 (7.2, 2.5, 6.7, 7.7, 2.6). Leg formula: II–IV–I–III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca 28 intermarginal denticles.

COPULATORY ORGAN.As in diagnosis. Epigynal field roughly triangular, slightly rounded on antero-lateral sides. Anterior bands touching epigynal field, short and slightly curved. Slit sensilla situated outside of epigynal field beside anterior bands. Lateral lobes distinctly separated from each other, only partly covering median septum, especially the middle part. First winding of IDS slightly S-shaped in dorsal view. Fertilization ducts located posteriorly, their tips dorso-mediad ( Fig. 8A–C ).

COLOURATION IN ETHANOL. Dorsal shield of prosoma dark yellowish-brown, with distinct striae, and slightly V-shaped marking located between fovea and posterior eyes (this latter area slightly more intensely reddish brown), with black lateral margins and additional submarginal narrow band on each side. Sternum yellowish-brown, with light yellowish lanceolate patch medially; ventral coxae yellowish-brown with each one lighter patch in proximal half. Labium and gnathocoxae deep brown with yellowish distal tip. Chelicerae dark brown, slightly bulged frontally, best seen in dorsal view. Opisthosoma dorsally, dark brown, with some irregular yellow pattern especially in anterior half; ventrally yellowish-brown with indistinct irregular tiny dots anteriorly to medially ( Fig. 8D–E ).

Distribution

China (Guizhou Province) ( Fig. 10 ).
