Figs 3–4

Diagnosis

Female of this new species can be distinguished from most of the species of Heteropoda by the unique combination of having a transversal rim on a freely visible median septum ( Fig. 3A–C; Jäger 2001: fig. 16h–j; Li et al. 2013: fig. 1a–f) and is most similar to those of H. amphora Fox, 1936 and H. schwalbachorum Jäger, 2008 , but can be distinguished from the latter species by: 1. median margins of lateral lobes strongly diverging anteriorly (vs converging in H. amphora and only slightly diverging in H schwalbachorum ); 2. first winding of IDS barely covered by posterior part (vs not covered in H. amphora and H. schwalbachorum ).

Etymology

The specific name is derived from the Latin noun ‘ lucerna ’, meaning ‘oil lamp’, referring to the anterior part of IDS in dorsal view; name in apposition.

Measurements of palp and legs: palp 11.7 (3.2, 1.7, 2.3, –, 4.3); I 39.3 (9.8, 3.4, 10.6, 11.5, 3.8); II 46.8 (11.9, 4.8, 12.6, 13.8, 3.5); III 33.1 (8.9, 3.7, 8.7, 8.9, 2.6); IV 36.8 (10.8, 3.4, 9.6, 10.3, 2.6). Leg formula: II–I–IV–III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca 38 intermarginal denticles.

COPULATORY ORGAN. As in diagnosis. Epigynal field wider than long, with short and basally wide anterior bands. Lateral lobes are widely separated from each other, and not covering the median septum. Fertilization ducts are separated about one width of posterior part of IDS ( Fig. 3A–C).

COLOURATION IN ETHANOL. Dorsal shield of prosoma reddish-brown to slightly yellowish-brown, with bright transversal crescent submarginally on posterior part, and longitudinal stripes covered by hairs around fovea. Chelicerae deep reddish-brown. Sternum, labium and gnathocoxae are yellowish-brown to reddish-brown. Opisthosoma dorsally yellowish-brown, with three pairs of six dots, and a dark-colored marking at posterior part; ventrally yellowish-brown, without obvious markings ( Fig. 3D–E).
