Description

Genus Udzungwastreptus Enghoff gen. nov.

urn:lsid:zoobank.org:act: 83A888D7-740C-4F3A-AEE0-09B56F6FCA92

Type species

Udzungwastreptus marianae Enghoff gen. et sp. nov.

Other included species

None.

Diagnosis

Differs from other trachystreptoform genera by the combination of an unmodified anterior margin of the collum, largely hairless prefemoral lobes of the first pair of male legs, closely appressed to the coxosternum, a ribbon-like free part of the telopodite with a slender accessory lobe branching off ca at midlength, and a simple solenomere originating subapically from the margin of the telopodite.

Etymology

Named after the Udzungwa Mountains, in recognition of their astonishing biological richness; ‘- streptus ’ is a common ending of names of genera of Spirostreptidae, probably derived from the Greek ‘ streptos ’, meaning twisted. Masculine.

Remarks

Udzungwastreptus gen. nov. belongs in group “γ) Télopodite en gouttière ou en bandelette” (telopodite like a gutter or a ribbon) of Demange & Mauriès, 1975. In the key to trachystreptinine genera of Demange & Mauriès (1975), Udzungwastreptus runs to Calostreptus Cook, 1896 with which it shares the lamellate borders of the posttorsal telopodite and the slender solenomere originating from the margin of the telopodite. Also, the prefemoral lobes of the first pair of legs is similar in the two genera (very flat, closely appressed to coxosternum). The new genus differs from Calostreptus as shown in Table 3. See Fig. 24.
