Lordiphosa denticeps species group View in CoL
Drosophila (Hirtodrosophila) denticeps species-group, Okada, 1967: 3.
Lordiphosa denticeps species-group: Zhang, 1993b: 144.
Diagnosis.
Male foreleg tarsomeres I to III often with sex combs (Figs 1B View Figure 1 , 2D View Figure 2 ). Surstylus with numerous recurved setae on ventral portion of inner surface in addition to primary prensisetae on caudobasal margin (Figs 1C View Figure 1 , 2F View Figure 2 ). Ventral margin of cercus tapering or truncated, fringed with a row of stout spines (Figs 1C View Figure 1 , 2F View Figure 2 ). Aedeagus membranous, hirsute apically, fused with posterior, roof-like gonopod (Figs 1E View Figure 1 , 2H View Figure 2 ). Oviscapt with numerous lateral ovisensilla (Figs 1F View Figure 1 , 2I View Figure 2 ).
Remarks.
Okada (1967) proposed the Lordiphosa denticeps group as a new species group of Hirtodrosophila (a subgenus of Drosophila at that time), including two species so far described, Lordiphosa denticeps Okada & Sasakawa, 1956 and Drosophila tripartita Okada, 1966. However, it had been noticed that these two species have aberrant morphological characters inconsistent with the definition of Hirtodrosophila . Three more species were subsequently added to this species group ( Okada 1971, Singh and Gupta 1981). Then Okada (1990) transferred the members of this species group to Lordiphosa (a subgenus of Drosophila at that time), but considered that the Drosophila denticeps group was synonymous with the Drosophila nigricolor group proposed by Laštovka and Máca (1978). Then, Grimaldi (1990) elevated Lordiphosa to the generic rank, and Zhang (1993b) resurrected and redefined the Lordiphosa denticeps group as a species group independent from the Lordiphosa nigricolor group in the genus Lordiphosa .
