Paraphyrosylus acrosticalis(Parent): Hardy & Kohn, 1964: 251. Conchopus acrosticalis(Parent): Takagi, 1965: 52; Masunaga et al., 2005: 439. Thambemyia acrosticalis(Parent): Meuffels & Grootaert, 1984: 152; Bickel & Dyte, 1989: 406; Nishida, 1992: 98, 1994: 92, 1997: 78, 2002: 95; Yang et al., 2006: 255.
Diagnosis. Small-sized species ( 2.9–3.2 mmin body length) characterized by 1st flagellomere twice as long as thickness; halter yellow. In male, M1+2 not thickened, apical section of M3+4 2.4 times as long as discal crossvein; fore tarsomere 1 with small basal lobe 1/3 as long as tarsomere 1, rather weak ventral bristle at midlength, and weak apical swelling; longer dorsal bristle of fore tarsomere 2 at middle; mid tibia flattened, and with long erect bristles and setae on anterior and posterior surfaces; mid tarsomere 1 short setose; ventral lobe of hypopygium very broad on apical 1/2 and slightly longer than cercus.

Distribution. Hawaiian Islands (Hawai‘i, Maui, Läna‘i, Moloka‘i).
Remarks. This species is most closely related to Conchopus ciliatus sp. nov.in having simple M1+2 and M 1 inboth sexes, and the male of the latter has the following combination of characters different from those of C. acrosticalis: thicker pollinosity of mesonotum; basal lobe of fore tarsomere 1 larger and with many shorter marginal setulae; ventral lobe of hypopygium much shorter than cercus.
