8D45952F316BFFB11B5AE1BEC625FE1D.taxon	description	BUTTERILL (2015) discussed the variation of the number and shape of papillae in the larval terminal segment among the Schizomyia species, ranging from four setose pairs to a single corniform pair, and the absence or presence of cercilike (dorsobasal) lobes in the ovipositor. Additionally, it was observed that the male gonocoxite of the Neotropical species is oblong instead as almost rectangular in non-Neotropical species of Schizomyia (Fig. 7).	en	Urso-Guimarães, Maria V.

Examined material. 2 ♂, 2 pupal exuviae, 1 pupa, 1 larva from BRAZIL, São Paulo: Ribeirão Preto (21 ° 22 ’ 10.61 ” S, 48 ° 15 ’ 58.99 ” W), reared from leaf galls of Bauhinia holophylla, collected 21. xi. 2001, emerged 25. xi. 2001; Dr. Olga Kotchetkoff-Henriques coll. and det. Gall and biology (Fig. 12). Leaf galls in Bauhinia holophylla (Fabaceae): globular, hairy, pale brown to redbrownish, changing the color as the gall matures, unilocular. Pupation occurs in the gall. New remarks to Schizomyia tuiuiu and comments on host plant. Schizomyia tuiuiu was described based on female and pupae sampled emerged from galls in Bauhinia rufa. The specimens herein described are males, exuviae and larvae emerged from galls in Bauhinia holophylla from Ribeirão Preto, SP. I compared the common structures of adult and pupa specimens and verified that the pupal characters of the two localities do not have morphological divergences, as well as the morphology of the thorax, legs and head (except for antenna, with sexual dimorphism). With the description of the larva, pupal exuvia of male and male of S. tuiuiu, it is possible to point out some differences from the congeneric species by having a discrete mediodorsal lobe on the posterior margin of the larval eighth abdominal segment, two rounded lobes on the terminal segment of the male exuvia, and apical tooth of gonostylus with a row of partially fused strong spines. The original description described the association of S. tuiuiu with Bauhinia rufa (Bong.) Steud. and the new specimens were reared from B. holophylla (Bong.) Steud., suggesting a new host plant to S. tuiuiu. But, examining the taxonomy of the Bauhinia species (VAZ, 2003, 2015), Bauhinia rufa var. cordata (Vogel) Benth. is a heterotypic synonym of Bauhinia holophylla with geographical distribution in Midwest and Southeast Brazil, instead of B. ruffa distributed only in Goiás and Minas Gerais (VAZ, 2003). Therefore, from now, the host plant of Schizomyia tuiuiu is Bauhinia holophylla due to the synonymy of these species.	en	Urso-Guimarães, Maria V.

8D45952F316EFFB41AFCE0B8C074FD39.taxon	discussion	Schizomyia maricaensis Sousa & Maia, 2007 was described from Restinga de Barra de Maricá / RJ inducing rosette bud galls in Tetrapterys phlomoides (Malpighiaceae). Herein, I am recording a new locality of geographical distribution to this species, which pupa and female emerged from swollen leaf veins of an unidentified liana with vein leaf swollen were collected in ciliary forest vegetation area in Ribeirão Preto, state of São Paulo, Brazil. The specimens were identified as S. maricaensis due to the characters of the female ovipositor (Fig. 13) and the unique terminal segment of pupa, bilobed and sclerotized (Fig. 14). Pupation occurs in the gall.	en	Urso-Guimarães, Maria V.

8D45952F316EFFB51AFCE2F8C7CDFE3A.taxon	discussion	Although adult characters are important for identification of genera in Asphondyliini, immature characters are essential for distinguishing species, once adult characters are very similar at the species level. For his reason, from the ten Neotropical species of Schizomyia, two are not included in this key because the larval instar is unknown, and the adult characters are indistinguishable: S. ipomoeae obtained from flower bud galls of Ipomoea sp. (Convolvulaceae) distributed in Guadeloupe FWI and St. Vincent, and S. stachytarphetae, obtained from seeds of Stachytarpheta cayennensis and S. jamaicensis (Verbenaceae) in Guadeloupe FWI and Trinidad. GAGNÉ & MENJIVAR (2008) divided the Western Hemisphere species of Schizomyia in two groups, the first with hook-like tarsal claws and empodia nearly as long as the claws, including the Neotropical species S. ipomoeae, S. macropillata, S. santosi, S. serjaniae, S. stachytarphetae, and S. tuiuiu, and the second with falcate tarsal claws and empodia no more than one-third of the claws length, which includes the Neotropical species S. loroco, S. manihoti, S. spherica, and S. maricaensis. Other character shared by the first group of Neotropical species of Schizomyia are the light and dark-banded flagellomeres in Schizomyia loroco, S. impatientis, and S. rivinae, also present in S. macropillata, S. santosi, S. stachytarphetae, and S. tuiuiu. Other important character to separate species of the genus is the variation in the terminal papillae of the larval terminal segment, ranging from four setose pairs to a single corniform pair (KOLESIK & BUTTERILL, 2015). To the Neotropical species with known larvae, the ranging vary from four pairs of small setiform papillae in S. spherical; three corniform and one setiform very long in S. tuiuiu and S. manihot; and one corniform and three setiform in S. macropillata, S. santosi, S. serjaniae and S. loroco. The variation in the larval and some of the adult characters in Neotropical species of Schizomyia allows the construction of a key for these species.	en	Urso-Guimarães, Maria V.
