As a subgenus of Limonia or Dicranomyia:
Limonia (Sivalimnobia)
Dicranomyia (Sivalimnobia)
Alexander, C.P. 1963. New or little-known Tipulidae from eastern Asia (Diptera). LI. Philippine Journal of Science 92: 220.
Sivalimnobia is defined by the modifications to the rostral projection of the male hypopygium. The rostral projection is strongly sclerotized and equipped with a strong spine near its apex. The basal tubercle of the spine and bend in the projection give the apex of the projection a triangular appearance. An additional slender strong spine is placed separately on the ventral gonostylus in close proximity to the base of the rostral projection.
Head: Anterior vertex suppressed. Rostrum length less than that of the remaining head. Maxillary palpus length shorter than or subequal to that of the remaining head; palpomeres subequal. Antennae: 14 articles; basal antennomeres oval, distal segments becoming elongate.
Wing: Coloration of cell and veins variable; stigma present or absent; anal angle of wing present, slightly constricted. Wing venation: Sc1 short, aligned or slightly removed from Sc2; both elements ending at or after the origin of Rs; R1+2 in near general alingment with R2; two branches of Rs (R4, R5) attaining wing margin; two Medial veins (M1+2, M3) attaining wing margin; discal cell (dm) present; CuA crossvein entering M near split of M; two Cubital veins (CuA1, CuA2) attaining wing margin; two Anal veins (A1, A2) attaining wing margin.
Male hypopygium: 9th tergite (9t) and sternite (9s) separated by lateral division; posterior margin of 9th tergite simple to medially excavated by the expansion of lateral margins. Mesoventral lobe of gonocoxite present. Gonostylus bifid, styles subequal; dorsal style a slender falcate sclerotized lobe; ventral style typically a bulbous lobe, equipted with two accessory lobes, a slender basal spine and a slender rostral projection that has a triangularly produced apex epuipped with a single stout spine. Aedeagus simple with one or two terminal openings. Proctriger simple, without modification.
Sivalimnobia is a group of 15 species at a are strongly represented in the Oriental Region (13 species) and in particular from India (9 species). As with most Oriental species their distributions are known from single collections, however, the two Palearctic species of the subgenus are both widely distributed.
The larval habits of this subgenus are unknown.
