Subgenus Verhoeffiella Absolon, 1900

Type species: Heteromurus (Verhoeffiella) cavicola Absolon, 1900 : p. 429 Diagnosis of Heteromurus (Verhoeffiel la). The diagnosis of the subgenus provided below is provisional, as diagnostic characters are unknown in several species.

Medium to large size (1.6–5.3 mm). Eyes absent. Body white, yellowish or pale orange, usually with pigment as orange dots. Scales present, rounded, their surface covered with numerous short spicules arranged longitudinally. Mac present dorsally on head and body, in small number, with typical arrangement (not known in several species). Ant. I divided in two subsegments, Ant. II entire, Ant. III and IV annulated. Antennae of various length, slightly shorter to longer than body. Abd. IV 1.5 to 2 times as long as Abd. III (contradictory statements in the original description of H. (V.) dallai , where the ratio is given as “nearly two times” and “2.8-3 times” elsewhere in the text. This last ratio would be unusual, rather pointing to a Pseudosinella species). Unguis thin and elongate, usually with one inner pair of small basal teeth, and one inner small unpaired tooth. Tita with thin, acuminate tenent hair. Dens devoid of spines. Mucro bidentate with basal spine.

Remark. The subgenus Verhoeffiella only differs from Heteromurus by the annulation of Ant. III.
