Obelostreptus proximospinosus Krabbe, 1982

Fig. 2A–D

Obelostreptus proximospinosus Krabbe, 1982: 419 . Abb. 267.

Material examined: Holotype ♂: TANZANIA: Usambara Mts. Amani , at Dodwe River, in rotten wood, c. 1000 m, 31.vii.1974, I. Bødker-Enghoff & H. Enghoff ( ZMUC). Additional material: numerous further specimens from Amani ( ZMUC) .

Remarks: Examination of many specimens (including the holotype) housed in the ZMUC revealed that the drawing of the gonopod coxite made by Krabbe (1982) is slightly erroneous. According to Krabbe, the distal part of the coxite forms a unique lobe, but our observations clearly show that this part of the coxite is bilobed ( Fig. 2B ). Other than that, the description and drawings are adequate. SEM illustrations of first leg and gonopod are given in Fig. 2 .

Females slightly longer and wider than males; vulva poorly sclerotized, located in a pouch behind coxosternite of second legs. Valves smooth with an elongated apical appendix ( Fig. 2D ).
