Note: We received five specimens from FMNH all of which we are considering as syntypes. However, we note here that all of them have different dates from Bierig (1934: p. 334, “ III. 28 de 1934”): three specimens of 30.III.34, one XI. 34 and one 12.IV.34. The last one is also from a different locality, “ Rangel ”. There are at least six provinces in Cuba with localities named as Rangel, but there is one of them named as “ El Pinar del Rangel ”, in Artemisa (t. l), which can be the locality written on that label ( GeoNames 2016).
Diagnosis. Hypotelus insulanus is similar to Hypotelus pusillus and differs in abdominal segment 8: tergite 8 of male with posterior margin somewhat truncate and sternite 8 of male with posterior margin weakly pigmented ( Fig. 52 View FIGURES 48 – 58 ), apex of median lobe of aedeagus straight in lateral view ( Fig. 61 View FIGURES 59 – 74 ); sternite 8 of female with posterior margin rounded ( Fig. 76 View FIGURES 75 – 82 ).
Redescription. BL: 2.1–3.0 mm, BW: 0.5–0.7 mm. Body slightly convex; dorsal surface glossy; light brown to brown, except elytra yellowish; appendages lighter than body, except mandibles. Dorsal integument of head and pronotum entirely with fine punctures and undulate microstriae; elytra with dispersed fine punctures and only one longitudinal finely punctate stria close to elytral suture.
Male. Head. Supra-antennal area slightly prominent. Antennae reaching half-length of elytra; antennomeres 3, 5, 7, 9 and 11 with longest setae on inner face; scape with prominent tooth on inner face; antennomeres 2 and 3 of equal length, 5–11 gradually increasing in length toward antennal apex. Mandibles symmetrical. Mentum 1.6 times wider than long.
Thorax. Pronotum wider than long (PW/PL=1.3); anterior angles rounded; apical half with somewhat parallel sides and basal half gradually narrowing toward the base; with complete internal mid-longitudinal ridge and slight longitudinal median sulcus only on basal half. Elytra somewhat longer than wide (EL/BW=1.1), covering partially or not abdominal tergite 3.
Abdomen. Tergite 8 with posterior margin somewhat truncate; sternite 8 with posterior margin rounded and weakly pigmented ( Fig. 52 View FIGURES 48 – 58 ); tergite 9 with short ventral struts; sternite 9 with posterior margin truncate and with two pairs of long setae, the internal longest; tergite 10 at posterior margin emarginate, with short fringes and four setae on each side ( Fig. 56 View FIGURES 48 – 58 ). Median lobe of aedeagus with apex rounded in ventral view; curved shape and apex straight in lateral view ( Figs. 61–62 View FIGURES 59 – 74 ).
Female. Similar to male except for: antennae shorter, scape without prominent tooth on inner face and without the longest setae on antennomeres 3, 5, 7, 9 and 11; abdominal tergite 8 with posterior margin rounded; sternite 8 with posterior margin regularly pigmented and with short setae on posterior margin ( Fig. 76 View FIGURES 75 – 82 ); tergite 9 without ventral struts; tergite 10 slightly rounded at apex ( Fig. 85 View FIGURES 83 – 108 ); bursa copulatrix as H. pusillus ; ovipositor consisting of a pair of weakly pigmented hemisternites and a pair of more apical coxites, and with many long setae on apex; spermatheca as Fig. 86 View FIGURES 83 – 108 .
Geographical records. In the current study, the species was examined from Cuba (Artemisa). Blackwelder (1943) also listed the species from Cuba (Cayamas), Jamaica (Saint Thomas and Santa Isabel), Hispaniola: Dominican Republic (La Vega) and Saint Vincent. Herman (2001) listed it from the West Indies [ Caribbean islands ]. Peck (2005) listed Cienfuegos “Ci” as a province of Cayamas ( Cuba) and cited the province Pinar del Rio “PR” as the type locality of this species ( Fig. 114 View FIGURE 114 ).
Biological notes. In the original description, Bierig (1934) commented that five specimens were found under the bark of fallen “almácigo”; according to this author, they were apparently preying on fly larvae but this behavior has not been confirmed.
Blackwelder (1943) cited that the Cuban specimens were collected “on ceiba”; that is, on a silk cotton tree, presumably under the bark; the Jamaican specimens were taken from under bark of the silk cotton tree and tropic birch, as well as ‘flying at dusk’.
