Diagnosis — Rostral anterior margin without incision. Lamellar cuspis without dent. Setae in short. Sensilli with verrucose globular head. Bothridia with deep incision, without swelling or projection. Depressions and dorsosejugal scissure absent. Humeral region with small triangular projection. Ten pairs of notogastral setae. Genito-anal setal formula: 6-1-2-3. Lyrifissures iad located along, near anterior margin of anal aperture. Epimeral setal formula: 3-1-3-3. Trochantera III and IV bearing carina without sharply pointed apex. Monodactylous.
Material examined — One female (NSMT-Ac 13633): from point B; 11 exs. and 2 parts of body, slides Nos. 596-604 bearing the label " Tegeocranus velatus " in the Michael collection.
Measurements — Body length 336 µm; width 229 µm. Body colour light brown.
Supplementary description — Morphological variation in shape of lamellar cuspis, sensillus, and situation of adanal lyrifissure iad, type B, B, and A used in figs 6 and 7 by Fujikawa (1999), respectively, that is, the present specimen has narrow cuspis, elongate sensillus, and enclosed angle of the adanae lyrifissure pair iad, 170º. Genital plates bearing g 1 and g 2 inserting at the same level. Measurements (µm) of segments of legs: [Right-left]: I([?-16]-[66-50]-[24-23]-[38-34]-[39-38]), II([?-31]-[71-57]-[20-27]-[34-36]-[31-31]), III([43-43]-[43-46]-[18-19]-[37-32]-[32-31]), IV([50-53]-[50-54]-[21-23]-[46-43]-[37-36]).
Distribution — Cosmopolitan.
Remarks — Three specimens from Matsushimacho belonging to the genus Tectocepheus have a body surface ornamented "as with a veil" ( Michael, 1880), and the ornamentation has densely, dark, large granules ( Fig. 15A View FIGURE ). Lyrifissure im of the present specimen aligned transversely anterior to opisthonotal gland gla.
