The name Evandromyia spelunca sp nov has been,given in regards to the meaning of cave in Latin. Results and Discussion, The morphological characters of the new species permit. included in the Evandromyia genus in the cortelezzii. complex This complex consists of three species Evan. dromyia corumbaensis Galati Nunes Oshiro Rego,1989 Evandromyia cortelezzii Brethes 1923 and. Evandromyia sallesi Galv o Coutinho 1940 These, species are morphologically close and often confused.
causing errors in its specific identification 5,The males of the genus Evandromyia present the. Figure 6 Evandromyia spelunca sp nov paratype female gonocoxite with a tuft of bristles basal and compact. Pharynx and cibarium Bar 100 m, the paramere is simple or branched the lateral lobe. apex is thin and the females present the relationship. spermatheca is globular with diameters approximately between the lengths clypeus head wider than 1 3 eye. equals to the others of group The head of the sper head less than 1 2 and spermathecae with variable. mathecae present some fine bristles inserted in the apex body The cortelezzii complex belongs to the cortelezzi. The individual and common sperm ducts are smooth series of the Barretomyia subgenus This series presents. walled the latter being short compared to the first The as main morphological characteristics males with the. individual duct is 197 199 12 4 n 8 in length and paramere and aedeagus simple the gonostyle with upper. the common duct 47 48 2 7 n 8 Cercus 119 125 external spine implanted in his middle and lower spine. 15 7 n 10 long inserted in the basal third Females with the globular.

The separation of the females from the others of the. complex is more confused and was not always possible. usually when the spermathecae are not present or totally. visible However the new species can be separated from. the Ev cortelezzii and Ev sallesi Figure 12 by sper. mathecae and characteristics of their ducts individual.

The new species can be separated from others of the. cortelezzii complex through morphological characters. All the males of the complex are very close being sepa. rated by the following characteristics paramere which. provides more similar aspect to Ev cortelezzii and Ev. sallesi however with the internal suture the curvature. and the shape of the paramere being enough to separate. the new species from the other two closer see Figures. 3 9 and 10 Ev sallesi presents the paramere with the. most consistent shape compared to all other species so. being the most robust Figure 9 The suture that, divides the inside of the paramere is more central and.
