Description
Genus Trogolaphysa Mills, 1938
Diagnosis. Pigmentation variable, specimens ranging from darkly pigmented to completely devoid of pigments (cave forms). Scales present, variably ciliated, covering at least Ant. I–II, dorsal and usually ventral head, dorsal trunk and ventral face of furcula; legs usually without scales. Dorsal-anterior cephalic bothriotricha present. Dorsal chaetotaxy reduced on Th. II, Th. III and Abd. I, chaetotaxy complete or almost complete in other segments, with few macrochaetae and several microchaetae. Ant. IV simple or annulated, never subdivided. 8+8 to 0+0 eyes. Labial chaeta L2 normal, never reduced. Th. II–Abd. V with ms and sens formula 10|10100 and 11|011–3, respectively. Abd. II to IV bothriotricha formula as 2+2/3+3/3+3. Manubrium lacking strong spines (at least as seen on dens), but with or without elongated thin ciliate spiniform chaetae. Dens with one or two rows of conical spines and/or elongated ciliate spiniform mac; mucro short, square or rectangular, with 3–5 teeth (adapted from Soto-Adames & Taylor 2013, Silva & Bellini 2015, Soto-Adames 2015).
Remarks on Brazilian fauna. The Brazilian species of Trogolaphysa are: T. aelleni Yoshii, 1988, T. formosensis Silva & Bellini, 2015, T. hauseri Yoshii, 1988, T. hirtipes (Handschin, 1924), T. millsi, Arlé 1939, T. tijucana (Arlé & Guimarães, 1979) and T. ernesti sp. nov. (Abrantes et al. 2012, Silva & Bellini, 2015). Most of these species present incomplete descriptions following current taxonomy of Entomobryoidea. Descriptions of ventral head, dorsal body and manubrial chaetotaxy of T. aelleni, T. hauseri, T. hirtipes, T. millsi and T. tijucana are needed to further understand such fauna. We could only compare these species with T. ernesti sp. nov. using color patterns, number of eyes, empodial and distal furcula morphology, among other few aspects.
The most dissimilar Neotropical species of Trogolaphysa is possibly T. formosensis. The species present scales on legs, enlarged Th. III and an unusual disposition of Abd. IV bothriotricha (Silva & Bellini 2015). Such characters suggest the species present a close relationship with Campylothorax (and for that, possibly Trogolaphysa as well), or even an intermediate position between both genera, hypotheses which should be tested under a phylogenetical approach.
