Genus Ocnophila Brunner, 1907

(Figs 1–13)

Ocnophila Brunner, 1907: 309. Type species Ocnophila integra Brunner, 1907, by subsequent designation of Hebard (1919).

= Parapygirhynchus Brunner, 1907: 316. Type species Parapygirhynchus catenatus Brunner, 1907, by subsequent designation of Zompro (2001). Synonymized by Zompro (2001): 233. See Brock et al. (2023) for a complete reference list

Remarks. Ocnophila integra was described based on both sexes but the females were proven to belong to a different genus (Zompro 2001) and its true female was proposed to be the lectotype of the junior synonym Parapygirhynchus catenatus Brunner, 1907, from the same locality as the male lectotype of O. integra. However, the occurrence of a closely related species nearby, O. iphicla, described from both sexes, could put into question which male belongs to which female. We confirmed the matching of sexes by the significant difference in robustness of both pairs and further by records of a mating pair of O. iphicla from the citizen-science online platform iNaturalist (Maleno 2019) (Fig. 11).

Diagnosis. Apterous. Head short in dorsal view, eyes small and projecting less than hemispherical. Thorax with granules, including along the length of mesoepisternum and metepisternum. Median segment very short. Legs relatively thin, with strong swelling at the base of the metafemur. Male. Abdomen relatively short; tergum X short in relation to anterior terga, wider than long, elevated in lateral view; cerci short and slightly incurved. Sterna V and VI with circular dense tuft of setae near posterior margin.Poculum well developed, round, with anterior region of sternum IX well developed and wide. Thorn pads with one or two prominent incurved sclerotized spines each. Phallic organ with dorsal sclerite in “b” shape, i.e., a subquadrate anteriormost area with a thin, somewhat straight prolongation at right side towards posterior, and with a curled claw-shaped basal sclerite with flat base. Female. Praeopercular organ a rugose swelling. Tergum VIII longer than VII, tergum IX with dorsal posterior region elevated. Tergum X poorly elevated, short in height, with posterior margin strongly developed, dorsoventrally compressed, lanceolate to conical, duck-bill shaped. Subgenital plate short, with round posterior margin, barely reaching epiproct.
