description: Martensopoda transversa sp. nov.
Figs 1–12, 26–28
Type material. Holotype male (PJ 1771) with label: 18. India: Kerala: Cardamon Hills, entre Pambanar et Peermade, 950 m, tamisages en forêt, près d'une rivière; 9.XI.1972; leg. C. Besuchet + I. Löbl. 2 female paratypes (PJ 1772–1773) with label: 49. India: Kerala: Cardamon Hills, Valara Fall; à 46 km au sud­ouest de Munnar, 450–500 m; tamisages dans la forêt près de la rivière; 25.XI.1972; leg. C. Besuchet et I. Löbl. (All material MHNG). 1 female paratype (PJ 1775) with same data as holotype. (SMF). [GPS Peermade: 9° 34' 0 0 N, 76° 58' 60 E; GPS Munnar: 10° 05' 60 N, 77° 04' 0 0 E]
Further material examined. 1 juvenile (PJ 1774) with label: 49. India: Kerala: Cardamon Hills, Valara Fall; à 46 km au sud­ouest de Munnar, 450–500 m; tamisages dans la forêt près de la rivière; 25.XI.1972; leg. C. Besuchet et I. Löbl (MHNG).
Diagnosis. Females with median septum being broader than in M. minuscula comb. nov., having an additional distinct pit at the anterior end of median septum, rims around copulatory openings building a small circle (Figs 9, 11), lateral loops of internal duct system extending posteriorly not to receptacula (Figs 10, 12). From the present material colour pattern of M. transversa sp. nov. seems to be less distinct than in M. minuscula comb. nov. (Figs 27–28).
Note. Characters of the male palp are not included as no male of M. minuscula comb. nov. is yet known. Characters are therefore listed in the genus description.
Etymology. The specific name refers to the organisation of the embolus, which is –unique within Heteropodinae– oriented transversally to the plane of the alveolus, i.e., running in a ventral loop (not in a prolateral loop as in other Heteropodinae genera); Latin: transversus – transverse; adjective.
