Subgenus Huangmyia Reinert, Harbach & Kitching, 2009

Type species: 

Stegomyia mediopunctata Theobald, 1905. 


Subfamily Culicinae, tribe Aedini, genus Stegomyia. Subgenus Huangmyia includes three of the four species included in the Mediopunctatus Subgroup of Huang (1977) ‒ the fourth species, St. rhungkiangensis, is currently without subgeneric placement. The nominotypical species includes two subspecies. Subgenus abbreviation – Hua.


The combination of characters that diagnose the subgenus in the phylogenetic study of Reinert et al. (2009) are indicated with an asterisk (*); characters that are shared with its sister subgenus Heteraspidion are indicated with a cross (†). ADULTS – *Ocular scales all narrow; maxillary palpus with white scales; scutum with broad median longitudinal pale stripe extending from anterior margin tapering posteriorly (*posterior acrostichal area with pale-scaled stripe) and forking at margin of prescutellar space, which lacks a patch of broad dark scales on either side, *scutal fossal scales all dark; †lateral patch of pale scales antealar and supraalar areas; †posterior dorsocentral area without pale-scaled stripe; dorsocentral setae absent; prescutellar setae well developed; scutellum with broad pale scales on midlobe and broad dark or white or both on lateral lobes; †postspiracular setae absent; pleura with distinct patches of broad pale scales, absent from hypostigial area, †lower prealar area and †metameron; knee spots present on mid- and hindfemora, absent on forefemur; midfemur without a median pale spot on anterior surface; all tibiae dark anteriorly, without pale bands, hindtibia with pale stripe on basoventral quarter; hindtarsus with basal white bands on tarsomeres 1,2; tarsomeres 3 and 5 entirely dark or with small basal pale band, tarsomere 5 entirely dark. FEMALE GENITALIA – Tergum IX broader than long (less than 1.5 times as wide as long), with well-developed posterolateral lobes, each with 3–5 setae. MALE GENITALIA – Tergum IX lobes separated by a large rounded median lobe; *gonocoxite without setae on basomesal area of dorsal surface; *gonostylus attached subapically, complex, shorter than gonocoxite, expanded *proximally, *narrowed distally, *with elongate lobe on lateral surface, expanded part with numerous fine setae and *scales on dorsal side, distal part with *3 or more gonostylar claws; paraproct without ventral arms. LARVAE‒ †Seta 5-P branched; setae 9,10,12-M long, single, aciculate, seta 9-M stouter than setae 10,12-M; basal spine of meso- and metapleural setal groups long, straight and pointed; comb scales in a row on a sclerotized plate; *seta 7-II similar to seta 7-I; *seta 3-VII  ≥0.94 mid-dorsal length of segment X; seta 12-VII inserted at approximately same level as seta 13-VII; seta 1-S inserted beyond and in line with pecten; *saddle of segment 10 with long conspicuous spicules, each usually pointed apically; *seta 2-X ≥0.90 length of seta 3-X. PUPAE – Seta 1-II well developed, dendritic with many branches; *seta 6-II equal to or shorter than seta 7-II; seta 2-IV,V inserted on line lateral to seta 1; genital lobe of males short and broad, about as wide as long. See genus Stegomyia.

Mattingly (1965) provided information and illustrations for St. mediopunctata (as Aedes mediopunctatus) and St. perplexa (as a subspecies of Aedes mediopunctatus), and Matsuo et al. (1974) described and illustrated its egg of St. perplexa. Huang (1977) described and illustrated the three species of the subgenus.

Phylogenetic relationships: 

Huang (1977) observed that subgenus Huangmyia (her Mediopunctatus Subgroup) shares some features with species she classified as member of two subgroups, the W-albus Subgroup (which includes two species of Stegomyia currently without subgeneric placement) and the Annandalei Subgroup (= subgenus Heteraspidion). Subgenus Huangmyia was recovered as sister to subgenus Heteraspidion in the phylogeny of tribe Aedini (Reinert et al., 2009) based on cladistic analyses of extensive morphological data. Subgenus Xyele was recovered as the sister of these two subgenera.

Bionomics and disease relations: 

Species of subgenus Huangmyia inhabit bamboo groves, forests and open woodland areas principally in hilly and mountainous areas. The immature stages are usually found in bamboo stumps and bamboo internodes, but they are sometimes also found in split and cut bamboo, holes of stumps, logs and trees, and the axils of Pandanus and Nipa palm. Females bite humans. 

Members of subgenus Huangmyia are of no apparent medical or economic importance to humans.


Species of subgenus Huangmyia are known to occur inmnortheastern and southwestern India, peninsular Malaysia, Sri Lanka and Thailand, and from southern China to Taiwan and the Philippines.
