Type-species: Coelindroma fungosa Kramer, 1967 by original designation.

Diagnosis ( Kramer, 1967; Marques-Costa, 2008): General color faint yellow with reddish-orange maculae or band on crown, pronotum and mesonotum and large black median macula on median portion of apical third of crown ( Figs 23–25 ); carina separating face and crown ( Figs 26–28 ); ocelli on transition between crown and frons; lateral margins of clypeus with slight median constriction or parallel-sided ( Figs 2 , 13 ); forewings with four apical and two anteapical cells; male pygofer with ventral tooth or hook; anal tube without processes ( Fig. 16 ); plates fused except at apex and often with few macrosetae distally ( Figs 5 , 17 ); connective Y-shaped ( Figs 8 , 20 ); style with mesal lobe hooked ( Figs 7 , 19 ); and aedeagus elongate and simple ( Figs 9 , 22 ).

According to Kramer (1967), Coelindroma can be separated from Neocoelidiana DeLong, 1953 , by the presence of macrosetae on the subgenital plates, the elongated aedeagus, and the simple anal tube.

Coelindroma resembles Tozzita Kramer, 1964 , Neocoelindroma Marques-Costa & Cavichioli, 2007 and Tetralidia Marques-Costa & Cavichioli, 2008 , in having the forewing with indistinct venation, except apically; subgenital plates fused in the basal two thirds (except in Coelindroma cornuta sp. nov. fused in basal half), without a dorsoapical tooth and the aedeagus with the shaft long and slender. It differs from these genera in having the forewing with two anteapical cells and the anal tube without basal processes.

In a phylogenetic analysis of Neocoelidiinae genera ( Marques-Costa, 2008), Coelindroma is sister to Tozzita Kramer, 1964 , sharing the following synapomorphies: hind tibiae with anteroventral (AV) setal row present only in apical half and connective longer than half length of styles. It differs in the position of the ocelli, which in Tozzita are located on the crown near the anterior margin, but in Coelindroma are located on the anterior margin of the head, at the transition between crown and frons; the lateral margins of the clypeus in Tozzita are convergent apically, but in Coelindroma are parallel-sided or with a slight median constriction; the male pygofer has a spatulate dorsoventrally flattened apex in Tozzita , but in Coelindroma the apex is rounded or acute, never spatulate; the connective is V-shaped in Tozzita and Y-shaped in Coelindroma .

Another genus near Coelindroma is Neocoelindroma , which resembles the latter in having a black spot at the apex of the crown. Neocoelindroma differs from Coelindroma by the black coloration of the head, presence of a long coronal suture, hind tibia anteroventral (AV) setal row with two short separated setae on the apical third; while in Coelindroma , row AV has a greater number of setae distributed over its apical half; in Neocoelindroma the male pygofer has a tooth at the apical third on the ventral margin (tooth on basal half of ventral margin in Coelindroma ) and the connective is approximately one third of the length of styles.
