Differential diagnosis

Orphnus mysoriensis   is similar to O. medvedevi   sp. nov. in having the pronotum with a more or less developed tubercle on the base medially and the endophallus with one group of spinules. It differs from the latter in body length (8.0–10.0 mm, as opposed to 4.6–6.0 mm in O. medvedevi   sp. nov.), spinules of endophallus as a rather dispersed group of more than 10 spinules (as opposed to a compact cluster consisting of less than 10 spinules in O. medvedevi   sp. nov., Fig. 1G View Fig vs Fig. 3G View Fig ), and tubercle on the base of pronotum normally with two punctures (as opposed to always smooth tubercle in O. medvedevi   sp. nov.).

Variation

Body length of the examined specimens varied from 8.0 to 10.5 mm (males) and from 7.0 to 9.0 mm (females). Head and pronotum armature in males varied from well-developed with long lateral pronotal processes and frontoclypeal horn ( Fig. 2A View Fig ) to excavated pronotum with gibbosities aside of the excavation and frontoclypeal tubercle ( Fig. 2C View Fig ), with intermediate variants ( Fig. 2B View Fig ).

Distribution

The species is distributed rather widely on Sri Lanka except for the eastern part ( Fig. 1H View Fig ).
