Micromartinia Amsel, 1957 , revised status, valid genus

Type species: Botys mnemusalis Walker, 1859 , type locality: Amazon Region (= M. sanguiflualis (Lederer, 1863) and M. caudalis (C. Felder, R. Felder & Rogenhofer, 1875)) ( Figs. 19–30 ).

Diagnosis: Distinct basal and antemedial lines not visible, orbicular and claviform spots adjacent to antemedial area ( Figs. 19 , 24, 26 ). Hind leg with distal spurs equal to length midleg spurs. Male genitalia ( Figs. 20–22 , 29–30 ) with an apically round uncus without a medial cleft, transtilla with posterior arms to costa of valva and anterior arms a cup-like, sclerotized, “shelf” medioposteriorly (in Pantographa the transtilla is medially flat); cornuti lacking, vesica with fine scobinations only. Second abdominal tergite with a prominent, lengthwise membranous fold with lateral triangular pouches pointing anteriorly, Pantographa lacks the lateral triangular pouches. Female genitalia ( Figs. 23 , 25, 27 ) with signum 2 unequal-sized, small, sclerotized circles, each with a short, medial spine (the medial spine absent in Pantographa ); with a highly sclerotized, elongated area at entrance of corpus bursae (not found in Pantographa ).

Description: Head: Labial palpus upturned, 2 nd segment 6 times as long as 3 rd segment; maxillary palpus short, only as long as 3 rd segment; ocellus with a dark, sclerotized band basally, clear apically; chaetosemata absent; antenna, male with scales dorsally, without scales and with long, hairlike cilia, each hair slightly longer than an antenna segment, female similar but with very short cilia. Thorax: Forewing length range= 15–19 mm. Forewing venation: Sc to 2/3 length of costa. R from about ¾ length of discal cell; Rs 1, Rs 2+3, and Rs 4 close together from anterior angle of discal cell, Rs 4 running parallel for a short distance, then diverging toward outer margin. M 1 from anterior angle of discal cell to outer margin; base of M 2 and M 3 close to CuA 1. CuA 2 from apical fourth of Cubitus vein. CuP ill-defined, very faint, slightly longer than discal cell. 1A+2A well marked to outer margin; 3A a loop slightly less than one third the length of 1A+2A. Hindwing venation: Sc+R 1 and Rs stalked for half-length of Medial vein beyond discal cell. Origin of M 1 from Rs; origin of M 2 and M 3 close to CuA 1. Three Anal veins well marked. Forewing pattern ( Figs. 19 , 24, 26 ): Basal area variable, yellow to brown, basal line not visible, white basally to claviform spot, antemedial line not visible, antemedial area adjacent to orbicular and claviform spots, spots light yellow with a brown outline, median line faint, reniform spot almost square, yellow with brown outline; postmedial line brown straight, slightly inward at M 2, often light yellow basally from M 2 to CuA 2, curving inward to posterior margin, dark brown shade from apex or Rs 4 to posterior margin; subterminal line not present; terminal line dark brown; fringe variable. Retinaculum scales anterior to CuP. Hindwing pattern ( Figs. 19 , 24, 26 ): Postmedial line variable, dark brown, one thick line, straight, or less thick and slightly curved from costa posterior margin, finger-like scalloped pattern external to postmedial line from M 2 to CuA 2; variable basal shade dark yellow to dark brown; discal spot present, variable light to dark brown; subterminal line not present; terminal line dark brown; fringe variable. Frenulum: Female with 2 spines, male with 1 spine. Legs: Foreleg with tibial epiphysis, midleg with one pair of subequal tibial spurs, hind leg with two pairs of tibial spurs, distal spurs equal to length of midleg spurs. Tympanal organ: Pons tympani prominent, post tympanal area with sclerotized outer margin, tergo-sternal sclerite highly sclerotized, processus tympani small or not visible, 2 nd segment tergite with a prominent, lengthwise membranous fold, with lateral triangular pouches pointing anteriorly, praecinctorium bilobed, membranous. Male genitalia ( Figs. 20–22 , 28–30 ): Uncus broad to tegumen, shorter than valvae, half the length of tegumen, uncus apex round without medial cleft, distally, dorsally with long, non-deciduous setae; subscaphium prominent, sclerotization variable; valvae round apically with well-developed, square-shaped, cup-like fibula, saccular medial lobe absent or very flat, well-developed group of long, deciduous scales internally on distal fourth of costa; transtilla posterior arms extending to costa of valva perpendicular to fibula, medially flat with a suture, transtilla anterior arms extending to base of valva forming a cup-like, sclerotized “shelf” medioposteriorly (not flat); juxta u-shaped, slightly sclerotized; saccus elongated and pointed; coremata lateral to saccus, elongated with 2 tufts of scales (1 tuft is sometimes deciduous) with a medially sclerotized rod; phallus with cornuti lacking, vesica with fine scobinations. Female genitalia ( Figs. 23 , 25, 27 ): Anterior apophyses as long as posterior apophyses; antrum not sclerotized, complete without bands; ductus seminalis about 1 mm anterior to ostium bursae; ductus bursae slightly longer than corpus bursae, lightly scobinated throughout; highly sclerotized, elongated entrance of corpus bursae; signum 2 round circles, 1 larger in circumference with a small, medial spine, 1 very much smaller in circumference.

Species examined: Micromartinia mnemusalis (Walker, 1863) , rev. comb. ( = sanguiflualis Lederer, 1863 , and caudalis (C. Felder, R. Felder & Rogenhofer, 1875)) ; Micromartinia gorgonalis Druce, 1895 , n. comb., rev. stat. ( Figs. 24–25 ); Micromartinia cyrisalis ( Druce, 1895) , n. comb. ( Figs. 26–30 ).

Remarks: The three species illustrated here clearly show the external diversity of the genus; M. gorgonalis is transferred from Pantographa and M. cyrisalis is transferred from Pilocrocis Lederer. Druce (1895) listed the type material of Phostria cyrisalis as three examples from Chiriqui (Coll. Staudinger), Bugaba, and Volcan de Chiriqui (NHMUK), Panama. We designate the male specimen figured by Druce from Bugaba as the lectotype to stabilize the name of this species, abdomen undissected, Lectotype designated, and 2 other specimens as paralectotypes.
