Tinamotaecola Carriker 1944: 86 , figs 1d, e. Type species: T. andinae Carriker, 1944 (by original designation). Tinamotaecola ; Hellenthal et al. 2002: 136.

Diagnosis. A genus belonging to the “ Degeeriella -complex” of Clay (1958), identifiable by the following adult features:

Head: longer than wide ( Figs 2, 3 ), forehead rounded and circumfasciate with conspicuous marginal carina uninterrupted in the middle, and with the edge of the ventral preantennal suture thickened on each side, becoming a continuation of the ventral carina and fused distally with the complete marginal carina; dorsal preantennal suture (dprs) developed, reaching the bases of the very long anterior dorsal setae (ads); a pair of dorsal submarginal setae (dsms) displaced backwards and included within the dorsal preantennal suture; prenodal setae (pns) medium long; antennae similar in both sexes; ocular seta (os) very long and placed dorsally; preocular seta (pos) medium long and placed sub-laterally; marginal temporal setae (ts) 2, 4 and 5 very short, 1 and 3 very long.

Thorax: as in Fig. 1 . Pronotum with single, long, lateroposterior postspiracular seta. Metanotum without anterior setae, but with 9–13 marginal posterior setae, including one small spiniform seta and one long trichoid seta each side. A median elongate and pigmented sclerite (mes) extending from mid-metanotum to abdominal segment II ( Fig. 4 ). Meso and metasternal plates with 1–2 setae.

Abdomen: as in Fig. 1 . Terga without anterior setae except for an antero-medial pair on tergite II; tergites II–VIII divided at midline; IX–XI fused and with a median anterior notch. A very long postspiracular seta on each side of terga III–VIII. Without well-defined sternal plates. Male genitalia as in Figs 14–16 : basal plate longer than wide and ellipsoidal, parameres long and sharply tapered, mesosomal complex with characteristic shape, genital sac elongated with small tubercles ( Fig. 17 ), penis slender and unpigmented. Female subgenital plate roughly rounded, with two irregular rows of setae: one formed by medium fine marginal setae, another of short spiniform submarginal setae ( Fig. 18 ).

Etymology. Not specified by Carriker (1944), but Tinamotaecola is formed by the prefix Tinamotae - (= of or from Tinamotis ) and the Latin suffix - cola (= to inhabit).

Remark. Hellenthal et al. (2002) divided the four species of this genus into two well defined species-groups, a criterion followed here. The species groups are characterized as follows:
