ANOPHELINM 



ANOPHELINiE. 



Definition. — Culicidse with straight proboscis; palpi long in both 

 sexes; occiput mostly with upright forked scales, never with flat 

 lateral scales. Thorax with scales or hairs, scutellum never trilobed, 

 with scales or hairs. Post scutellum nude. Abdomen with hairs or 

 scales. Eggs laid singly, and not in rafts. Larvae without respira- 

 tory siphon. 



This is a most important subfamily, because it contains the species 

 which are known to carry malaria. The list of known carriers 

 will be found in Chapter XXXV. (p. 883) . 



It is important for the student of tropical medicine to be able 

 to recognize the genera and species of the more important Anophe- 

 linae. For this purpose we give the following tables taken from 

 Theobald's 'Manual of the Culicidae,' vol. v., 1910. For fuller 

 information the original work must be consulted, but it must be 

 admitted that there is a growing opinion that Theobald's genera 

 imperceptibly merge with one another, and are not founded on 

 essential points; and Edwards has returned to two genera, Anopheles 

 and Bironella, therefore in Chapter XXXV. (p. 883) we will give 

 another classification when considering the anophelines which carry 

 malaria. 



Subfamily Anophelin^e Theobald, 1901. 

 Table of Genera. 



A. First submarginal cell very small — Bironella Theobald. 



B. First submarginal cell large: — 



I. Antennal segments with dense lateral scale-tufts — Chagasia Cruz. 

 II. Antennal segments with outstanding scales on the second segment 

 and more appressed ones on the first. At least one abdominal 

 segment with long flat more or less spatulate scales — Calvertina 

 Ludlow. 



III. Antennal segments without dense lateral scale-tufts: — 



1. Thorax and abdomen with hair-like curved scales: — 



{a) No flat scales on head, but upright forked ones. 



(a) Basal lobe of male genitalia of one segment. 



(1) Wing scales large, lanceolate— y4wo^7«e/g5 Mei gen. 



(2) Wing scales mostly small, or narrow, or slightly 



lanceolate, costa spotted^ — Myzomyia Blanchard. 



(3) Wings similar to (2), but with fourth longitudinal 



vein very near base of third. Prothoracic lobes 

 with outstanding scales — Neomvzomyia Theo- 

 bald. 



(4) Wings with patches of large inflated scales — 



Cycloleppteron Theobald. 



(b) Basal lobe of two segments :-- — 



_. Prothoracic lobes with dense outstanding scales — 



Feltinella Theobald. 

 (6) Median area of head with some flat scales; prothoracic 

 lobes mammillated. Wing scales lanceolate — Stethomyia 

 Theobald. 



2. Thorax with narrow curved scales; abdomen hairy: — ■ 



{a) Wing scales small and lanceolate; head with normal forked 

 scales — Pyretophovus Blanchard. 

 . . (6) Wing scales broad and lanceolate; head with broad scales 

 not closely appressed, but not forked or fimbriated — • 

 Myzorhynchella Theobald.
