Type material
Holotype ♀: DOMINICA: Parish of St. Joseph, Springfield Estate, 13.34667°N, 61.3683°W, 430 m, 15–20 Mar. 2003, (M. E. Irwin, M. Shepard), Malaise trap [BBSL]. Allotype ♂: topotypical [BBSL]. 10 paratype ♀♀: topotypical [AMNH, BBSL (5), CUIC, NMNH, PCYU, SEMC].
Diagnosis
Females of Habralictus gonzalezi can be distinguished from Habralictus insularis by the following: face mostly green (mostly copper in Habralictus insularis), clypeus with few punctures limited to medial area (numerous punctures throughout in Habralictus insularis), supraclypeal area virtually impunctate (distinctly punctate in Habralictus insularis), pronotal lobe dark brown (yellow-orange in Habralictus insularis), and metatibial anterobasal hairs brown (off-white in Habralictus insularis).
Males of Habralictus gonzalezi can be distinguished from Habralictus insularis and Habralictus claviventris by the following: supraclypeal area and lower paraocular area imbricate, punctures obscure (smooth, distinctly punctate in Habralictus claviventris and Habralictus insularis);mesoscutum and mesoscutellum without evident punctation (punctures present albeit fine in Habralictus claviventris and Habralictus insularis); head and mesosoma bluish-green (bright green in Habralictus claviventris and Habralictus insularis).

Metatibia with brown, plumose hairs (off white on posterior surface); basoventral hairs densely pectinate (almost palmate), directed apically. Metabasitarsus with brown hairs on anterior surface. Lateral surface of propodeum with long, sparsely-branched, plumose hairs (2.5–3.5 OD). Posterior surface of propodeum with short, appressed hairs. Metasoma: Terga sparsely pubescent; anterior surface of T1 with sparse, erect hairs (1–1.5 OD). Dorsal surface of T1 and T2 largely bare. Dorsal surface of T3–T5 with posteriorly directed hairs (1–2.5 OD), longer on T5 and laterally portions of (up to 3.5 OD).
