Anthalona sp. Van Damme, 2011

Specimen examined. 10 parthenogenic female. Three mounted (two whole mounts (UST ZRC 0140, 0141, one dissected UST ZRC 0142). Five subjected to SEM. Two were damaged beyond repair.

Description. Recently established in 2011 by Van Damme, the genus can easily be recognised by their flower-like (lobed) lateral head pores. Body is oval with a prominent rostrum. Has a characteristic connected main head pores and lobed lateral head pores. Eye larger than its ocellus. Labral plate axeshaped. Post abdomen wide and short and with an S-shaped appearance. Terminal claw long with one small accessory basal spine ( Fig. 13 , 14 ). Specimen found in Lake Lanao is morphologically similar to A. alonopsiformis described by Brehm in 1933 by its terminal claw but extensive analsysis is still needed to elucidate its identity.

Distribution. Cagayan: Lake Calig; Mt. Province: Chico River; Lanao del Sur: Lake Lanao ( Fig. 7 )
