status

subgen. nov.

Subgenus Physopeltoides subgen. nov.

Type species. Physopelta (Physopeltoides) dentipes sp. nov., here designated.

Diagnosis. Body smaller (males 11.18–12.26 mm, females 11.39–12.47 mm). Antennomere 1 short, much shorter than both antennomere 2 and length of pronotum. Sexual dimorphism not expressed. Callar lobe distinctly gibbose in both sexes ( Figs 60–61 View Figs 60–63. 60–61 ). Profemora of both sexes strongly incrassate ( Figs 51 View Figs 48–51 , 60–61 View Figs 60–63. 60–61 ), ventral surface with longitudinal furrow, row of small denticles on each side of furrow, and two larger teeth anteapically on dorsal surface ( Figs 50–51 View Figs 48–51 ). Tibiae ventrally unarmed in both sexes. Ventral sides of meso- and metafemora with small denticles along their entire length. Stridulatory organs lacking, procoxa ventrally without tubercle ( Figs 48–49 View Figs 48–51 ). Peritreme of metathoracic scent gland oriented longitudinally, crescent-shaped, projecting both anteriad and posteriad of ostiole (as on Figs 68–69 View Figs 64–69 ). Paramere with apex short and narrow, outer margin basally with small angulate process ( Figs 55–59 View Figs 52–59 ).

Differential diagnosis. Physopeltoides subgen. nov. and Neophysopelta share the following characters, suggesting a possible sister relationship of both taxa: i) antennomere 1 shorter than antennomere 2; ii) profemora incrassate; iii) meso- and metafemora ventrally with longitudinal furrow of small denticles. However, in Physopeltoides subgen. nov. the characters ii) and iii) occur in both sexes, whereas in Neophysopelta these are developed only in males. Afrophysopelta subgen. nov. differs from Physopeltoides subgen. nov. In its profemora not incrassate and meso- and metafemora ventrally unarmed. On the other hand, Afrophysopelta subgen. nov. and Physopeltoides subgen. nov. share the same shape of peritreme and paramere.

Etymology. The name of the subgenus is derived from the nominotypical subgenus Physopelta using the Greek suffix - oides, meaning ‘resembling, similar to; the gender is masculine.
