Genus Carinophallus Gen. Nov.

Branchinella Daday 1910 ; Linder 1941; Tiwari 1958; Baid 1975; Hamer 1994, 1999; Belk & Brtek 1995; Brtek 1996; Brendonck & Riddoch 1997; Brtek & Mura 2000. Branchinema Wolf , in Daday 1910.

Diagnosis ( Figure 1 B). Fully extended penes extending to base of third post­genital abdominal segment. Basal portion of penes rigid, cylindrical, each bearing a single large, triangular, ventral carina with apex directed laterally. Rigid basal portion each bearing a single small, truncated, cylindrical, medial tubercle, with apical patch of denticles. Distal eversible portion of penes soft, cylindrical, with two large medial spines, two medium sized ventrolateral spines, and two medium sized apical spines. Distal portion of ventrolateral surface with small proximally directed spines. Penal apex truncate, directed apically. Brood pouch sub­cylindrical to sub­spherical, extending to the base of the first abdominal segment. Male with frontal appendage present. “Antenna­like” appendages absent.

The morphology of the eversible portion of the penes in Carinophallus and Thamnocephalus similar. One species from Africa and southern Asia (see below).
